FM MP3/MP4 Wireless hearing aid with FM/MP3/MP4 watch-typed remote controller

摘要

In the case of a conventional hearing aid, the hearing loss is simply amplified and used to listen to the external sound, but in the case of the present invention, the FM radio, MP3, and MP4 functions are first mounted on the clock-type transmission remote control unit 22 and the data is transmitted. The RF modulation and transmission module 12 is used to transmit to the reception hearing aid unit 31 through the transmission antenna 13, and the signal is received by the RF reception antenna 19a embedded in the reception hearing aid to receive the RF inside the reception hearing unit. The module 19b. The demodulator 20 and the hearing aid module 21 allow the hearing person to select and listen to FM radio broadcast, MP3 music, and MP4 video as well as external sound through the receiver 37. Even if you are listening to or watching broadcasts, music, or video, there is an advantage that the hearing function works when you listen to the external sound at all. There is also a clock-type transmission remote control unit 22. You can easily operate with the desired function by using the operation key (27), and you can see the clock function time through the display window 26, and sometimes you can also see the MP4 video. It was very inconvenient to operate the operation key because the hearing aid was not inserted into the case, but in the case of the present invention, there is an advantage that the operation is very convenient by adopting a watch-type transmission remote control unit worn on the wrist.;From now on, the operation principle and operation sequence of this paper will be explained (refer to Fig. 2 to 6).;First, Figure 2 is a block diagram of the clock-type transmission remote control unit 22, when the user wants to use only as a simple hearing aid, the user presses the microphone key to operate the microphone 4 from the operation key input unit 18, the corresponding microphone key is The microcontroller 16 is input to the microcontroller 16 and the microcontroller 16 recognizes this and outputs a related control signal so that the microphone 4 and the width width 5 are activated to start operation, and the switch 1 6 has an internal contact. When the sound signal absorbed from the microphone 4 is amplified by the amplifying unit 5, the amplification unit 5 is properly amplified and input to the mixer 11 through the switch 1 6, and the switch 2 9 inside the switch. Since it is controlled by the microcontroller 16 so as to be located at the contact point 3, and the FM receiving module 8 and the MP3 / MP4 playback module 10 are controlled by the microcontroller 16 to be inactive, the switch From 2 (9) ah No sound signal is also input to the mixer 11, so that only the signal input from the switch 1 (6) is output to the mixer output, and is input to the RF modulation and transmission module 12. The appropriately modulated signal is amplified through the transmission module. After that, it is output as a radio wave through the transmission antenna (7). Mic key is a single key that operates alone and is toggled at the same time. It is turned on once and turned off again, and it is turned on again when pressed again.;At this time, if the FM receiving key is pressed so that the FM receiving module is selected from the operation key input unit 18 while the microphone key is turned on, the corresponding key is input to the microcontroller 17 and recognized, and then the associated control from the microcontroller. The signal is output to activate the FM receiving module 8, and by moving the internal terminal of the switch 2 (9) to the position of the contact point 1, the FM broadcast signal received by the FM receiving module 8 is detected inside the sound After the signal is converted into a signal from the FM receiving module (8) is input to the terminal 1 of the switch 2, the output from the switch 2 is input to the mixer 11 and merged with the acoustic signal input from the microphone and then the RF modulation and transmission module ( 12) is RF modulated, amplified by the transmission module and then output as a radio wave through the transmission antenna (13). In this state, when the microphone operation is turned off by pressing the microphone key again, the sound signal input from the microphone 4 is cut off, so that the user can adjust only the FM radio signal. The FM receive key is independent of the microphone key but interoperable with the MP3 / MP4 play keys described below, so only one of the two keys is turned on.;The microcontroller recognizes this by automatically turning on the MP3 / MP4 play key to operate the MP3 / MP4 play module 10 while the FM receive key 8 is turned on so that the FM receive module 8 operates. By turning off and activating the MP3 / MP4 playback module and moving the internal terminal of switch 2 (9) from contact 1 to contact 2, the acoustic signal output from the MP3 / MP4 playback module 10 is connected to contact terminal 2 of switch 2. When there is an acoustic signal input through the output from the switch 2, input to the mixer, and the microphone, the two acoustic signals are combined with each other and then input to the RF modulation and transmission module 12, RF-modulated, and then amplified in the transmission module Radio waves are output through the transmission antenna 13;The LCD driver and display unit 15 displays the input source currently selected and operating on the display window 26 using an icon form or a character and simultaneously displays time information input from the clock module 14. The video information is input from the MP3 / MP4 playback module 10 and displayed on the LCD screen.;The clock module 14 is configured to perform a clock function, and has the same configuration as a general electronic clock. The clock controller 14 is capable of performing and setting a time adjustment and an alarm function through a microcontroller.;In addition, when receiving and displaying a video signal from the MP4 player in the MP3 / MP4 playback module 10, the time display automatically disappears and the display changes to a video screen, and the time is temporarily displayed when the user wants to know the time. The operation key input unit 18 is provided with a time display button for performing the operation.;The clock function is always operated so that the time can be seen at any time. Even when the alarm is set, the alarm sound is transmitted from the clock module 14 and synthesized with the signals input through the mixer 11 when the alarm is set. It is output through the modulation and transmission module 12 and the transmission antenna 13. 3 is a block diagram of the reception hearing aid unit 31, after the RF modulated signal is detected through the RF reception antenna 19a, amplified by the RF reception module 19b, and then output to the demodulator 20. After the demodulated signal is separated from the demodulated signal, the additional identification signal is separated, and then the identification signal is decoded to confirm the coupling with the transmitter, and then the audio signal is determined to be a stereo signal or a mono signal. After determining whether the signal is on the right or left signal, the left receiver receives only the left signal and the right signal receives only the right receiver. In the case of mono, the hearing aid module determines whether to receive the left and right signals.
