[1] The present invention relates to a small size adaptor type MP3 digital recorder having a XLR-female input directly engaged to a broadcast microphone, and in particular to an adaptor type MP3 digital recorder having a direct engagement function for a broadcast microphone capable of a XLR-female connector input is integrally engaged to a MP3 recorder body in a small size MP3 recorder in such a manner that a small size adaptor type MP3 digital recorder is directly connected to a XLR-male connector that is an output terminal of a broadcast microphone, so that a broadcast equipment having a compact size, lightness and high performance is achieved. Background Art
[2] Generally, a journalist or report uses a recording apparatus in such a manner that an audio cable is connected with an interview microphone when collecting news or recording interview. In this case, the constructions of a microphone, audio cable, recording apparatus and monitor earphone are complicated. In addition, a recording equipment is heavy, so that it is inconvenient to use the above apparatuses.
[3] As a recording equipment that has been mainly used, there are a portable DAT, small size MD, portable cassette recorder, etc. In this case, a mechanical error frequently occurs in the above apparatuses. In addition, a motor is generally adapted in the above apparatuses. Therefore, battery consumption is increased.
[4] When journalist or report collects news or perform interview, the convenience is most important. However, in the conventional art, the interview recording system is complicated and heavy and has a short recording time and a short battery time. In addition, a mechanical error frequently occurs. Disclosure of Invention Technical Solution
[5] Accordingly, it is an object of the present invention to provide an adaptor type MP3 digital recorder having a direct engagement function for a broadcast microphone capable of overcoming the problems encountered in the conventional art.
[6] It is another object of the present invention to provide an adaptor type MP3 digital recorder having a direct engagement function for a broadcast microphone that does not
need a connection audio cable between a microphone and a recorder in such a manner that a small MP3 digital recorder is directly engaged to a broadcast microphone by an adaptor method and that is capable of achieving a compact size, lightness and high performance using a MP3 digital recorder instead a mechanical type audio recorder.
[7] In the present invention, an audio signal of a broadcast microphone having a XLR- male connector output is directly received by a XLR-female connector input and is amplified to 60dB through a microphone amplifier for thereby setting a certain recording level with a desired volume VR. An output of a microphone signal varied to a desired volume is connected with a line input of a MP3 digital recorder and is encoded. The encoded audio signal is stored as a digital signal and is reproduced when needed, so that the signal is used for monitor or broadcast. In addition, the files stored through USB port are stored in a computed and are edited. The files may be posted on the Internet. Description of Drawings
[8] The preferred embodiments of the present invention will be described with reference to the accompanying drawings.

[12] The present invention will be described in detail with reference to the accompanying drawings.
[13] Figure 1 is a view illustrating the construction in which a XLR-female input connector 1 and a MP3 digital recorder 10 are integrally engaged. Second, third and third input pins are MIC input terminals of XLR-female connector, and a first input pin is earth 2, and the second input pin is hot 4, and third input pin is cold 3, and the microphone is connected with three XLR input pins, so that a microphone audio signal is transferred.
[14] The XLR connector is generally called a canon connector, and male is '+' type, and female is '-' type. In the drawings, reference numeral 5 represents an engaging member of the canon collector and has a locking function capable of achieving a stable engagement when engaging with the MIC and preventing unlocking. In addition, reference numeral 6 represents a member capable of unlocking a locking state in such
a manner that the engaging member 5 is inwardly moved in the inner direction of the body of the connector when it is pushed in order to disengage the MIC. It returned to its original position by an inner spring.
[15] Reference numeral 10 represents a MP3 digital recorder, and 11 through 19 are operation switches of the MP3 digital recorder, and 11 is an operation handle by which it is possible to select various menu such as a recording level adjusting, an earphone volume adjusting, a recorded file movement, etc. 12 represents a display window for displaying an operation state and level of the operating MP3. 13 represents a hold switch for preventing an error operation. 14 is a MIC/LINE input selection switch for selecting a microphone and a line level for thereby recording. 15 is a microphone selection switch for thereby selecting dynamic and condenser microphones. When the condenser type microphone is selected, power is supplied to the condenser type microphone. 16 is a REC button (record button) during recording, and 17 is a play/ pause button. 18 is a stop button, and 19 is a power switch. 20 is a bottom structure of the present invention. 21 is a battery cover opened and closed when exchanging the battery. 22 us a USB port capable of moving the stored files to a computer or storing. 23 is a line output terminal (line output, 3.5mm stereo Jack), namely, an analog signal output jack used when reproducing a recorded audio signal wherein a line level (OdB) signal is outputted and is inputted into an audio editor and is used for broadcasting after it is edited. 24 is an earphone jack (phone output, 3.5mm stereo jack) capable of monitoring recording states by inserting the earphone during recording. When monitoring recording contents, it may be used by inserting the earphone.
[16] Figure 2 is a block diagram of the present invention. When an audio signal of - 60dB of the broadcast microphone 30 is transferred through the XLR-female connector 32 of the MP3 digital recorder directly connected with the XLR-male output connector 31, the audio level of 60dB is amplified by the MIC amplifier when selecting MIC based on a MIC/LINE selection cooperation switches 33 and 34 and is outputted as a line level signal. The signal is transferred to the MP3 input with a proper level based on an input level adjusting volume 35 and is encoded as a digital signal. Reference numeral 37 is a power supply circuit of the condenser type microphone. The power is supplied to the microphone by a phantom power SW 36. It is operated only when the MIC is selected by the MIC/LINE selection switch for thereby using the condenser type microphone. When recording with a signal of the line level, the MIC/LINE selection switch is selected to the line input for thereby recording, so that an audio input of OdB may be recorded.
[17] Figure 3 is a view illustrating an engagement of the present invention and illustrating a direct engagement of the present invention. It is directly engaged with the broadcast microphone integrally. It is a compact size and lightness. A very convenient structure is achieved. Industrial Applicability
[18] As described above, in the present invention, an adaptor type small size MP3 digital recorder having a XLR-female input is directly engaged to the broadcast microphone having a XLR-male connector output terminal for thereby achieving an integrated structure. Therefore, in the present invention, an audio cable between the conventional microphone and the recorder is not used. An integration structure is achieved. A small size and light recording system is achieved. Reporter or journalist can fast perform an interview with viewers, and a high quality recording is achieved.
[19] Since the present invention relates to an adaptor type small size MP3 digital recorder having a XLR-female, the user can select a microphone based on a desired recording characteristic. The system according to the present invention is inserted into the MP3 digital recorder input.
