1. Field of the Invention
The present invention relates to an application of MP3 player, and more particularly to a MP3 player having an exercise meter, which can play the music and at the same time detect the exercise amount and pulse rate of the user.
2. Description of the Related Art
In the prior art, the conventional audio players, such as MP3 player, CD player, can play music from the recording medium of compact disk, and provide the convenience for the user carrying with. Following with the increased functionalities, the new MP3 player product uses a repeatable read/write flash memory as the recording medium for the audio data. Except for the original music playing function, it also adds a data interface for updating the memory content as the user's data storage and a microphone interface for real-time recording the sound data as the user's recorder. Moreover, the music playing is not interrupted due to the affection caused by the user's vibration when using the flash memory as the recording medium for MP3 player. Thus, the sport enthusiasts often carry the MP3 players to enjoy both exercising and listening music.
Busy Modern life and diet habit have caused the danger to the people's health. So, it is necessary to have suitable exercise for the modern people. Normally, people will go to the gym or buy the running machine and other instruments for suitable exercising. But, because the busy life leads most people having no time for exercise, and no ideas about if it is enough for the exercising. Thus, there are some measuring meters in the market, for example the easy-to-carry pedometer, to provide the modern people calculating the daily exercise amount. However, in the prior art, the exercise meter and the MP3 player are in the same category of portable electronic products but not related application products developed. It is inconvenient for the sport enthusiasts needing to carry both products. Also, the conventional exercise meters only provide the real-time measuring display, but have no timing generator and memory for recording of the measuring data, which cannot provide the evaluation of the exercise amount over few days, one week or one month span.
Based on the related application products for exercise meter and MP3 player not developed in the prior art, the object of the present invention is to provide a MP3 player with the function of the exercise meter, which can detect the exercise amount of the user when playing music.
One object of the present invention is to provide a MP3 player with exercise meter for detecting the pulse rate of the user when playing music.
Another object of the present invention is to provide a MP3 player with exercise meter for recording the measuring data from exercise meter when playing music.
In a preferred embodiment according to the present invention, an audio player includes a memory unit for storing the compressed audio files; a DSP (Digital Signal Processing) processor for decoding the compressed audio file to generate the audio signal in a playing operation; an earphone for converting the audio signal into the sound; and a key input unit for transmitting the command by user's request to the DSP processor; which is characterized in:
the audio player further includes a vibration sensing component, wherein the vibration sensing component will generate a first signal following with the user's vibration and transmit to the DSP processor. The voltage variation for the first signal caused by vibration is used as the input signal for stepping counts, and the stepping input signal will be used as the walking-step counting value through the processing and accumulation of the DSP processor;
wherein the audio player further includes a display unit, and the DSP processor can output the message for walking-step counting value on the display unit;
wherein the audio player further includes a timing generator, so that the DSP processor can record the exercising time based on the first signal;
wherein the DSP processor can obtain the personal information for the user, such as height, weight, and step span, by the key input unit, and record in the non-volatile memory unit. The DSP processor can calculate the information of calorie consumption or exercising distance according to the personal information and the walking-step counting value for each exercising metering, and display and make records.
In another embodiment according to the present invention, an audio player further includes a memory unit for storing the compressed audio file; a DSP processor for decoding the compressed audio file to generate the audio signal in a playing operation; an earphone for converting the audio signal into the sound; and a key input unit for transmitting the command by user's request to the DSP processor; which is characterized in:
the audio player 20 further includes a heartbeat sensor, and the heartbeat sensor detects the heartbeat status of the user, and generates a second signal and transmits to the DSP processor, and the second signal is in response to the pulsing of the user, and is processed and accumulated by the DSP processor to become the heartbeat value;
wherein the audio player further includes a display unit, and the DSP processor can output the message for the heartbeat value on the display unit.
The MP3 player according to the present invention has the function of exercise meter. During the playing of MP3 files, the MP3 player can simultaneously receive the signals detected by the vibration sensing component or the heartbeat sensor, then the detected signals are processed and accumulated; and the messages about physical capacity after conversion are displayed on the display. Thus, the user can be acknowledged about the exercise achievement during exercising and listening music, and evaluate the long-term exercise amount based on the records of each exercising, or output the measuring record data for usage.
Although the present invention will be described in details with the attached figures from the preferred embodiments according to the present invention, the skilled artisan in the art should realize that they can modify the invention described in the application, and achieve the same effect as the present invention. Thus, it should be noted that the following description is only a broad disclosure to the skilled artisan in the art, and the contents should not be construed as the limitation to the present invention.
Firstly referring to
The MP3 player 20 according to the first embodiment further includes a vibration sensing component 22 for generating a first signal following with the user's vibration; and a signal filtering circuit 21 connected between the vibration sensing component 22 and the DSP processor 4. In the first embodiment according to the present invention, the first signal is in response to the user's vibration to generate the voltage variation, and the voltage variation is processed by the signal filtering circuit 21 as the step counting input signal. The step counting signal is transmitted to the DSP processor 4, and processed and accumulated by the DSP processor 4 to obtain the measured walking-step counting value. The measured walking-step counting value is then displayed on the display unit 23.
Furthermore, the DSP processor 4 can obtain the personal information of the user, such as height, weight, step span, from the key input unit 25, and record in the non-volatile memory unit 26. The DSP processor 4 can calculate the information of calorie consumption or exercising distance according to the personal information and the walking-step counting value for each exercising metering, and display and make records, and can also output the measuring record data for usage.
Further referring to
Furthermore, the DSP processor 4 can real-time detect the continuous heartbeat status, so as to monitor the loading of the user's physical capacity status. The DSP processor 4 can analyze the heartbeat status indicated by the second signal, and when occurring the abnormal conditions, such as too fast the heartbeat, the DSP processor 4 can interrupt the music playing, and generate an alert audio signal to the earphone 2 to remind the user. Therefore, the MP3 player 20 can be used as a monitor for the user with potential heart disease.
According to the embodiments shown in
Furthermore, according to the embodiments shown in
After the detailed descriptions of the preferred embodiments according to the present invention, the skilled artisan in the art can appreciate the various changes and modification without departing from the following claims and spirit. And, the present invention is also not limited to the implementation method of the embodiments of the present application. For example, the DSP processor in the MP3 player according to the present invention can further compute and process the detected signals and values to calculate the calorie consumption or fat burning index for the user.
