Description

Laser pointer, power supply, laser pointer control method, and power supply control method

The present invention relates to a laser pointer, a power supply, a laser pointer control method, and a power supply control method, and more particularly, inserted into a sound output terminal of an electronic device such as a mobile phone, a smartphone, an MP3, an audio device, and the like. Control method of laser pointer, power supply and laser pointer operated by sound source and circuit, and control method of power supply to maintain constant output regardless of manufacturer, model name, sales region, manufacturing region, etc. of electronic equipment It is about.

In general, the laser pointer is composed of a lens in the front of the laser diode, the rear of the battery consists of a power supply and a switch for supplying and cutting off the battery, the user operates the switch to supply the power of the battery to the laser diode When the laser diode is turned on, the laser is irradiated to the front of the laser pointer.

Such a laser pointer serves as an indicator rod for indicating a chart or a presentation screen at a meeting, a construction site, and a briefing session. Therefore, laser pointers are mostly miniaturized to be portable and easy to use.

Recently, a laser pointer is constructed in a portable terminal used by many people, such as Korean Patent Laid-Open Publication No. 10-2004-0026806, "Mobile communication terminal with a laser pointer." By providing an improved laser pointer integrated with a portable terminal, it is possible to prevent the hassle, such as battery replacement that can occur in a stand-alone laser pointer.

However, in the case of a portable terminal integrated laser pointer such as Korean Patent Laid-Open Publication No. 10-2004-0026806, in order for a user to use the laser pointer, the portable terminal and the portable terminal configured with the laser pointer or the laser pointer are configured. There is a problem in that the mobile terminal must be purchased separately.

In order to solve this problem, a removable laser pointer connected to an input / output port of a mobile terminal is also provided, such as Korean Patent Publication No. 10-2004-0014695 "Mobile communication terminal having a removable laser pointer."

In the case of a laser pointer using an internal power supply terminal of a portable terminal, there is a problem in that power is used differently for each portable terminal, so that each device must be developed separately.

In addition, in the case of the laser emitting device configured in the laser pointer, since the corresponding laser pointer can perform its basic function (instructing function) only by using a voltage higher than the voltage of the speaker terminal of the portable terminal, In case of 10-2004-0014695, there is a problem in that a sufficient voltage is not supplied to the laser emitting device of the laser pointer.

Advantages and features of the present invention and methods for achieving them will be apparent with reference to the embodiments described below in detail with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various forms, and only the embodiments are to make the disclosure of the present invention complete, and common knowledge in the art to which the present invention pertains. It is provided to fully inform the person having the scope of the invention, which is defined only by the scope of the claims. In addition, like reference numerals refer to like elements throughout.

Hereinafter, a laser pointer according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 13.

1 is a perspective view of a laser pointer according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of the laser pointer of FIG. 1, and FIG. 3 is a cross-sectional view taken along line A-A of the laser pointer of FIG. 1. 4 is a partial cross-sectional view for describing the operation of the laser pointer of FIG. 1.

First, referring to FIG. 1, a laser pointer 1 according to an embodiment of the present invention includes a body 10 having a laser outlet 11 formed therein, and an input terminal coupled to the body 10 and receiving power ( 60). The laser pointer 1 is input terminal 60 is inserted into the earphone jack of the portable electronic device, that is, the sound output terminal, and operates using the acoustic signal provided from the portable electronic device. That is, the left sound signal and the right sound signal applied from the earphone jack of the portable electronic device are used as a driving power source for driving the laser module (see 40 in FIG. 2) including the laser emitting device (see 100 in FIG. 5). .

On the other hand, the input terminal 60 to which the left sound signal and the right sound signal are input and the booster circuit unit (see B1 in FIG. 5) provided inside the laser module 40 have a power supply device for supplying power to the laser pointer 1. Configure. Such a power supply device supplies power by using an acoustic signal of a portable electronic device, and uses information of the portable electronic device from each device having various specifications according to the model of the portable electronic device or the country of use of the electronic device. It is controlled to reliably supply the appropriate size of power.

In addition, the configuration and control method of the power supply device need not be limited to the laser pointer 1, and various electronic modules (usable for short-range information communication from an optical module such as a camera module) that can be used in connection with a portable electronic device. Communication module such as a Wi-Fi module, or a variety of electronic modules that can be mounted on the existing or future portable electronic devices can be included.

Hereinafter, the laser pointer 1 will be mainly described, but the power supply device and its control method will be described in more detail later.

Meanwhile, the left sound signal and the right sound signal mean a control signal for outputting a sound output to the left speaker and a sound output to the right speaker among stereo sounds.

In the present specification, the sound signal is a signal of all bandwidths that can be applied through an audio output terminal such as an audio jack (or an audio terminal) of an electronic device, and not only human voice, but also various sounds and human hearing ranges. It is a signal that can output various kinds of sounds.

2 and 3, the laser pointer 1 will be described in detail. The laser pointer 1 includes a body 10, a diffusion lens 20, an elastic member 30, a laser module 40, and The input terminal 60 is included. The input terminal 60 may be coupled to the body 10 through the holder 50.

The body 10 is formed with a laser emission port 11 for emitting a laser on one side, and accommodates a laser module 40 for generating a laser therein. An input terminal 60 including a first terminal 61, a second terminal 62, and a third terminal 63 is coupled to one side of the body 10.

The input terminal 60 may be a passage through which driving power for driving the laser module 40 is input, and may be inserted into an earphone jack of a portable electronic device (not shown) to receive an audio signal. That is, the input terminal 60 is a structure that can receive a stereo sound signal from the earphone jack or headphone jack of various acoustic devices.

The input terminal 60 includes a first terminal 61, a second terminal 62, and a third terminal 63 to receive a general stereo sound signal. That is, the first terminal 61 receives the left sound signal, the second terminal 62 receives the right sound signal, and the third terminal 63 is used as a "signal return" from the earphone jack of the acoustic device. It is electrically connected to the common pin (ground pin). In this case, the first terminal 61 and the second terminal 62 are arbitrarily determined, and the terminal receiving either one of the left sound signal and the right sound signal is the first terminal 61 and the terminal receiving the other one. May be referred to as a second terminal 62.

The apparatus may further include a fourth terminal 64 through which a microphone signal is input / output or a control signal is input / output. However, the 3rd terminal 63 and the 4th terminal 64 are not necessarily a structure in the structure of the laser pointer 1, and can be added as needed.

The laser pointer 1 receives an AC sound signal from an earphone jack of various electronic devices for outputting sound and generates a driving voltage for emitting a laser. A process of converting an AC signal into a drive signal will be described later in detail.

The laser module 40 drives the laser diode by using the left sound signal, the right sound signal, and the booster circuit unit received from the input terminal 60. The left sound signal and the right sound signal may be configured as at least one of an AC signal and a square wave (pulse wave) and a sine wave (sine wave).

The laser module 40 includes a boost circuit section (see B1 in FIG. 5) and a laser emitting device (see 100 in FIG. 5). According to an embodiment of the present invention, the booster circuit unit B1 and the laser emitting device 100 are configured as one circuit in the laser module 40, but are not limited thereto. 100 may be used in connection with each other after being configured in a separate circuit. When the booster circuit part B1 is formed separately, the power supply device may be formed together with the input terminal 60 to be separated from the laser pointer 1 to be easily used to configure another electronic module.

The left sound signal and the right sound signal generated by a general audio device are usually AC signals. Therefore, a special sound source is required to operate most of the laser modules 40 controlled by direct current signals using the left sound signal and the right sound signal. Here, the special sound source means that the phase of any one of the left sound signal and the right sound signal is earlier or later than the other phase, and the phase difference between the left sound signal and the right sound signal is preferably 180 degrees.

Accordingly, the laser module 40 receives a signal adjusted so that the phase of either the left sound signal and the right sound signal is faster or later than the other phase, and uses the two signals as driving signals. The left sound signal and the right sound signal input to the laser module 40 preferably have a phase difference value of 180 degrees.

The boosting circuit (multiplication circuit) included in the laser module 40 will be described later in detail.

The laser is generated in the laser module 40, passes through the diffusion lens 20, and is emitted to the outside of the body 10 through the laser emission port 11. The diffusion lens 20 is accommodated in the body 10 and is interposed between the laser emission port 11 and the laser module 40. Therefore, the diffusion lens 20 contacts the at least some of the lasers generated by the laser module 40 to diffuse the laser, and emits a part of the diffused laser to the outside through the laser confirmation hole 12.

The laser confirmation hole 12 is formed through one end of the body 10, and at least a portion of the laser confirmation hole 12 overlaps the diffuse lens 20 so that a portion of the laser light diffused by the diffuse lens 20 is emitted to the outside. The laser light emitted through the laser confirmation hole 12 indicates that the laser pointer 1 is normally operating to emit the laser.

Since the laser light is a straight light, it is difficult to easily recognize the emission from the surroundings, and there is a danger of blindness when seen directly by the eye. However, the laser light emitted through the laser confirmation hole 12 has a very low light intensity, so that the operation of the laser pointer 1 can be safely confirmed.

The diffuser lens 20 has a laser through hole 21 through which a laser passes, and a diameter of the laser through hole 21 is preferably smaller than the width of the laser generated by the laser module 40. . The diffusion lens 20 need not be completely accommodated in the body 10, and may be attached to one side of the body 10 and exposed to the outside.

The elastic member 30 is interposed between the diffusion lens 20 and the laser module 40 to transmit an elastic force to the diffusion lens 20. The elastic member 30 provides a constant elastic force between the diffusion lens 20 and the laser module 40 to fix the diffusion lens 20 and the laser module 40. The diffusing lens 20 and the laser module 40 may have processing tolerances during processing or gaps during use. In this case, the elastic member 30 may prevent the diffusion lens 20 and the laser module 40 from shaking. Therefore, the diffusion lens 20 is always fixed at a constant position. The elastic member 30 may be a coil spring through the center.

Meanwhile, the laser module 40 and the input terminal 60 are fixed to the body 10 by the holder 50. Holder 50 may be formed in the receiving space of the input terminal 60 on the inside, one end is inserted into the body 10 can easily support the laser module 40.

Referring to FIG. 4, when the laser light L1 is emitted from the laser module 40, the laser light L1 is emitted to the outside of the body 10 through the diffusion lens 20. In this case, the width of the laser light L1 generated from the laser module 40 is greater than the diameter of the laser passing hole 21 of the diffusion lens 20. Among the laser beams L1 generated from the laser module 40, the laser beam L3 in contact with the diffusion lens 20 is emitted to the outside of the body 10 through the laser confirmation hole 12. In addition, the remaining laser light L2 is emitted to the outside through the laser emission port 11.

Hereinafter, a circuit included in the laser module will be described in detail with reference to FIGS. 5 to 9.

FIG. 5 is a circuit diagram of the laser module of FIG. 2, FIG. 6 is a graph showing waveforms of a left voice signal and a right voice signal, and FIG. 7 is a signal at nodes 'N1', 'N2' and 'N3' of FIG. 8 is a circuit diagram showing a modification of the laser module of FIG. 5, and FIG. 9 is a graph showing signal waveforms at nodes 'N1', 'N2' and 'N3' of FIG.

Referring to FIG. 5, two sound signals input to the input terminal 60 of the laser pointer 1 may be input to the boosting circuit unit B1 with a phase difference of 180 degrees. The left sound signal LS and the right sound signal RS are respectively input to the first terminal 61 and the second terminal 62 of the input terminal 60.

Referring to FIG. 6, the waveforms of the left sound signal LS and the right sound signal RS have a phase difference of 180 degrees with each other. The left sound signal LS of FIG. 6 shows a waveform between the first terminal 61 and the third terminal 63, and the right sound signal RS shows the second terminal 62 and the third terminal 63. It shows the waveform between.

The left sound signal LS and the right sound signal RS are out of phase with each other and are a kind of AC voltage having voltages of + a to -a.

The signal input to the first terminal 61 and the second terminal 62 and to the booster circuit unit B1 is an output signal of the node 'N1', as shown in the N1 graph of FIG. 7. That is, the left sound signal RS and the right sound signal LS of FIG. 6 are combined to generate a signal having a large amplitude.

The booster circuit unit B1 serves to increase the voltage of the input signal, and may increase a minimum voltage of the input signal (the voltage of the node 'N1') to a reference voltage (ground voltage). For example, when the input signal is a pulse wave having a voltage of + b to -b (where b is about 2a), the booster circuit part B1 sets the input signal to a voltage of + b 'to 0 (where b' is about). Can be converted into a pulse wave having 2b). In one embodiment, the booster circuit part B1 may include a capacitor connected in series to the input terminal and a diode connected in parallel to the input terminal.

The smoothing circuit unit B2 may perform a function of converting the boosted input signal into a direct current. Since the left sound signal and the right sound signal input to the input terminal 60 are basically analog signals, the smoothing circuit unit B2 converts the input signal into a DC voltage. For example, the smoothing circuit unit B2 may convert an input signal of a pulse wave having a voltage of + b 'to 0 into a direct current voltage having a voltage of b "(where b" is slightly lower than b'). . In one embodiment, the smoothing circuit unit B2 may include a diode connected in series to the input terminal and a capacitor connected in parallel to the input terminal.

The stabilization circuit unit B3 may perform a function of controlling the output of the laser emitting device 100 to be stable. For example, the DC voltage output from the smoothing circuit unit B2 may include a small pulsation voltage. This pulsation voltage may cause a change in output (brightness change) of the laser output from the laser emitting device 100 or may cause damage to the laser emitting device 100. Therefore, the stabilization circuit unit B3 may perform a function of preventing the output change of the laser due to the pulsation voltage. In an exemplary embodiment, the stabilization circuit part B3 may include a feedback control circuit including two transistors.

In addition, the laser emitting device 100 may include a light emitting device 100a for generating a laser and a light receiving device 100b for detecting light. The light receiving device 100b may receive a laser generated by the light emitting device 100a to generate a feedback signal. For example, when the output of the laser light generated by the light emitting device 100a is low, the output of the laser light may be increased by receiving a feedback signal from the light receiving device 100b. In addition, when the output of the laser light generated by the light emitting device 100a is high, the feedback signal of the light receiving device 100b is reduced to lower the output of the laser light so that the laser does not emit and fail. That is, the output of the laser light can be automatically controlled by using the light emitting device 100a and the light receiving device 100b.

Meanwhile, as shown in FIG. 8, the laser module (see 40 of FIG. 2) is deformed to include another type of booster circuit portion B1 ′ and stabilization circuit portion B2 ′, and in the booster circuit portion B1 ′. The step of boosting the input signal more than once may be to generate a boost signal. This will be described below.

Referring to FIGS. 8 and 9, as described above, the waveforms of the left sound signal (see LS of FIG. 6) and the right sound signal (see RS of FIG. 6) are 180 degrees out of phase with each other to form waveforms inverted from each other. Can be formed. At this time, the left sound signal LS is measured between the first terminal 61 and the third terminal 63, and the right sound signal RS is between the second terminal 62 and the third terminal 63. As measured at, it has the same pattern as shown in FIG. 6.

The signal input to the first terminal 61 and the second terminal 62 and to the booster circuit unit B1 ′ is an output signal of the node 'N1' shown in FIG. 8, and is the same as the N1 graph shown in FIG. 9. Has a pattern. That is, the sum of the left sound signal RS and the right sound signal LS is inputted with a large amplitude converted signal.

The acoustic signal passing through the node 'N1' reflects a relative potential difference between the first terminal 61 and the second terminal 62, and a specific reference potential (eg, the above-described ground pin may provide the reference potential). Based on the reference value), each measured voltage value is an AC signal having a potential difference as much as the sum of them.

10 and 11 are outputted while continuously changing a sound source having a frequency of 100Hz ~ 20KHz to each electronic device and measured the current in the short circuit. The short-circuit current is the current flowing when the terminals of the power supply are short-circuited. The magnitude of the current is the value obtained by dividing the terminal voltage by the internal impedance of the power supply when there is no load. The more output, the better.

17 and 18, a laser pointer control method, a power supply device, and a control method of the power supply device according to an embodiment of the present invention will be described in turn.

17 is a diagram illustrating a control screen of a portable electronic device.

Since the laser pointer 1 is driven by being supplied with power by a power supply device configured in the laser pointer 1, a specific control method of the laser pointer 1 may be the same as or similar to the control method of the power supply device. . Therefore, a detailed description of the control method of the laser pointer 1 will be described briefly with respect to the control method of the laser pointer 1 instead of the control method of the power supply device described later.

A control method of the laser pointer 1 will be briefly described by way of example with a portable electronic device (see 200 in FIGS. 12 and 13). The portable electronic device 200 provides a left sound signal and a right sound signal to the first terminal 61 and the second terminal 62 of the laser pointer 1, respectively.

As described above, the left sound signal and the right sound signal are either faster or later than the other phase, and preferably have a phase difference of 180 degrees. The left sound signal and the right sound signal may be configured of at least one of a square wave and a sine wave, and when the smoothing circuit is embedded, the left sound signal and the right sound signal may be converted into direct current and provided to the laser pointer 1.

The setting area 223 may be an area in which an icon is formed to control vibration, volume of a sound, and sensitivity of a mouse. As such, the laser pointer 1 may be easily controlled by touching the touch screen 220 or the like of the portable electronic device 200.

Hereinafter, a power supply device and a control method thereof will be described in detail with reference to FIG. 18.

18 is a flowchart illustrating a control process of a power supply device.

As described above, the power supply includes an input terminal (see 60 in FIG. 5) including a first terminal (see 61 in FIG. 5), a second terminal (see 62 in FIG. 5), and a boost circuit section (B1 in FIG. 5). Reference). One and the other of the left sound signal and the right sound signal of the electronic device are respectively input to the first terminal 61 and the second terminal 62, and the input signal is boosted by the booster circuit part B1 to increase the laser module and It can be used as a power source for driving various electronic modules connected to electronic devices. Such a power supply can be easily controlled in conjunction with a control program installed in the electronic device.

For example, a portable electronic device such as a smart phone (see 200 of FIGS. 12 and 13) may include a program therein for controlling a power supply. Such a program may be embedded in the portable electronic device 200 itself. If not, the program may be downloaded from the outside of the device through an app store or the like.

When a program for controlling a power supply device is installed in the portable electronic device 200, first, the portable electronic device 200 collects electronic device information (S100). Here, the electronic device information means information included in the electronic device such as the manufacturer, model name, sales region, manufacturing region (or country) of the electronic device on which the program for controlling the power supply is installed, program information installed in the OS electronic device, and the like. do.

The electronic device information is used to obtain the output value of the acoustic signal of the electronic device in which the program for controlling the power supply is installed. The electronic device information may be directly input by the user, for example, by providing an information input window to the user, and the electronic module inserted or connected to the electronic device or driven by the power supply device. When the control program of the is installed, it may be automatically extracted from the electronic device by the program. Alternatively, information may be obtained from a carrier through wired or wireless communication.

The output value of the acoustic signal of the electronic device is set differently for every electronic device, and the output value of the acoustic signal affects the driving voltage of the power supply device. When driving the laser module, the output value of the laser generated through the power supply device It will also have a significant impact on the output value. Therefore, in order to keep the laser output value constant, the output value of the acoustic signal must be kept constant.

In order to keep the output value of the sound signal constant, the output value unique to each electronic device is found, and the sound source is controlled accordingly.

The sound signal output value of the electronic device may also vary depending on the type of the laser module (see 40 of FIG. 2) driven by the power supply device. That is, the output control of the electronic device should be made according to the characteristics of the laser that the laser module 40 can output, which is done manually by inputting the serial number of the laser module 40 or the serial of the laser module 40. It can be done automatically by transmitting a signal containing the module information such as a number to the electronic device. The signal generated from the laser module 40 can be easily transmitted to the electronic device through the other terminal, not the first terminal 61 or the second terminal 62 of the input terminal 60, such a terminal is an example. For example, the terminal may be a microphone terminal for inputting / outputting a voice signal external to the electronic device.

That is, the output signal of the sound output terminal of the electronic device can be adjusted according to the information of the laser module 40 as well as the model information of the electronic device itself. In other words, a program for extracting and analyzing information of an electronic device, for example, an App, analyzes a transmission signal of the laser module 40 transmitted through a microphone terminal, and types of the electronic device and the laser module 40. The output can be adjusted flexibly according to the type of). This is very useful for the power supply to drive other modules other than the laser module 40. This enables the power supply to reliably supply power to not only the laser pointer but also various other electronic equipment by exchanging the modules. have.

Hereinafter, the control method of the power supply will be described in more detail.

Specifically, first, the output value of the sound output signal of the electronic device is extracted from the electronic device output data using the electronic device information (S110).

The electronic device output data means an output value of a sound output signal for each model of each electronic device. The electronic device output data compares the electronic device information with the electronic device output data, and compares the acoustic output signal of the electronic device with a program for controlling the laser pointer. Find the output. The electronic device output data may be data stored in the electronic device or stored in an external storage means to be connected and loaded through a wired or wireless communication network.

Knowing the output value of the sound output signal of the electronic device, the program can calculate the output range of the laser that can be generated, for example, via the power supply. Therefore, after extracting the output value of the sound output signal, the electronic device 200 controls the intensity of the sound source according to the output value of the sound output signal of the electronic device (S120).

The sound source may be generated inside the electronic device, or may be selected from among the one stored in the electronic device or the sound source pattern stored in the electronic device. The sound source may be stored outside the electronic device, for example, in a wired or It may be loaded after connecting through a wireless communication network.

The beam output of the laser pointer is often regulated by each country in consideration of safety. Therefore, it is possible to adjust the laser output according to the user's region, condition, etc. through the electronic device information. In addition, the voltage value of the sound signal itself is fundamentally small, and the regulation of the sound signal is also regulated differently from country to country, which also grasps electronic device information and provides appropriate output.

The sound source provided through the adjustment process of the control program is a stereo sound source capable of generating a left sound signal and a right sound signal. The sound source may be in the form of a wave, MP3, or the like, or may be generated in real time by the electronic device itself. By converting the sound source through the above-described process to generate an input signal and amplifying it one or more times, various types of electronic modules can be driven not only by the laser pointer but also by various kinds of electronic devices.

In addition, when the power supply device drives the laser module 40, in the region where the output of the acoustic signal is limited to a lower value than necessary, the output of the laser may be below an appropriate value even after the amplification process described above. In this case, the output of the laser may be increased by storing the driving signal of the laser module 40 in the form of pulse and intermittently applying it. At this time, if the frequency of the driving signal driven intermittently is properly adjusted, it is possible to obtain the effect that the continuous laser light is emitted. In the meantime, the intensity of the sound source may be adjusted by adjusting at least one of an amplitude and a frequency of the signal. The sound source may be generated in an electronic device, selected from a sound source pattern stored in the electronic device, or stored outside the electronic device, and may be loaded by being connected through a wired or wireless communication network.

Subsequently, the left sound signal and the right sound signal are output according to the sound source (S130).

The left sound signal and the right sound signal refer to a control signal for outputting sound through an audio jack of an electronic device, and one of the left sound signal and the right sound signal may be set earlier or later than the other phase. Preferably, the left sound signal and the right sound signal may have a phase difference value of 180 degrees with each other.

The left sound signal and the right sound signal are composed of at least one of a square wave and a sine wave, and may have a square wave or a sine wave or a mixed waveform thereof. The left sound signal and the right sound signal may be intermittently output.

Finally, the left sound signal and the right sound signal is provided to the power supply (S140).

The left sound signal and the right sound signal are used as driving power of the power supply device, and are provided to the laser emitting device (see 100 of FIG. 5) through a boosting process inside the power supply device.

In this way, the power supply device can stably provide the driving power by using the acoustic signal of the portable electronic device, and the various types of modules connected thereto can be driven regardless of the specifications of the electronic device and the national constraints. . As mentioned above, the power supply can also be easily used to drive an electronic module having a function other than the laser module 40 through this control method.

I can understand that. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive.
