(Sending audio data from teacher to student)
With reference to FIG. 5, a series of processes of the hearing aid system 1 will be described.
When the teacher transmits the voice transmission mode button 18a (S101), the teacher transceiver 10 transmits a voice transmission mode switching command to the voice data exchange 30 (S102).
When receiving the voice transmission mode switching command, the voice data exchange 30 switches to the voice data reception mode (S103). This is for enabling the teacher transceiver 10 to transmit audio data.

The voice data carried through the Bluetooth transmission path is received by the Bluetooth module 34 of the voice data exchange 30 and input from the Bluetooth module 34 to the voice distributor 32 (S105).

Here, the network connection determination means determines whether or not the student transceiver 20 is normally detected by the Bluetooth module 34 of the voice data exchange 30 (S106).
If it is determined that the Bluetooth module 34 has detected it normally, the audio data is transmitted to all of the connected student transceivers 20 via the Bluetooth transmission path (S107).
When the student transceiver 20 receives the audio data (S108), the student transceiver 20 outputs the audio data from the earphone 25 of the student transceiver 20 (S114).

On the other hand, when it is determined that the student transceiver 20 is not normally detected by the Bluetooth module 34, the detection signal transmitting means transmits a detection signal to detect the student transceiver 20 that is not connected ( S109). This detection signal is displayed on the display unit 35 (S110). For this reason, the teacher can grasp the students who cannot receive the voice data.
When the student transceiver 20 is detected by the transmitted detection signal, the student transceiver 20 transmits a response signal indicating the detection to the voice data exchange 30 (S111).
When the response signal is returned from the student transceiver 20, the voice data exchange 30 transmits the voice data to the student transceiver 20 (S <b> 112).
When the student transceiver 20 receives the sound data (S113), the student transceiver 20 outputs the sound data from the earphone 25 of the student transceiver 20 (S114).

That is, the audio data transmitted from the teacher transceiver 10 to the student transceiver 20 uses Bluetooth. For this reason, it is not necessary to assign the frequency to be used for each classroom, which is a problem in an environment where the conventional FM hearing aid is used.
In addition, since the Bluetooth connection confirmation can be realized by the display unit (35), the teacher can check the student attendance at a glance by looking at the display unit 35 at hand, which contributes to the improvement of convenience.

  Further, the student transceiver 20 is configured such that the Bluetooth unit 22 is detachably attached to the hearing aid 21.

When the student transmitter / receiver 20 presses the voice transmission mode button 28b when making a question to the teacher (S201), the student transmitter / receiver 20 transmits a voice transmission mode switching command to the voice data exchange 30 (S202).
When receiving the voice transmission mode switching command, the voice data exchange 30 switches to the voice data reception mode (S203).

Subsequently, when the student inputs voice data to the microphone 24 of the student transceiver 20, the inputted voice data is transmitted from the communication unit 27 of the Bluetooth unit 22, and is carried through the Bluetooth transmission path to be sent to the voice data. It is transmitted to the exchange 30 (S204).
The voice data carried through the Bluetooth transmission path is received by the Bluetooth module 34 of the voice data exchange 30 and input from the Bluetooth module 34 to the voice distributor 32 (S105).

Here, the network connection determining means determines whether or not the teacher transceiver 10 is normally detected by the Bluetooth module 34 of the voice data exchange 30 (S206).
When it is determined that the Bluetooth module 34 has detected it normally, the audio data is transmitted to the connected teacher transceiver 10 through the Bluetooth transmission line (S207).
When the teacher transceiver 10 receives audio data (S208), the sound output from the earphone 15 is transmitted to the teacher via the amplifier unit 16 (S213).

On the other hand, when it is determined that the teacher transceiver 10 is not normally detected by the Bluetooth module 34, the detection signal transmitting means transmits a detection signal to detect the teacher transceiver 10 (S209).
When the teacher's transceiver 10 detects its own device based on the transmitted detection signal, the teacher's transceiver 10 transmits a response signal indicating that it has been detected to the voice data exchange 30 (S210).
When the response signal is returned from the teacher transceiver 10, the voice data exchanger 30 transmits the voice data to the teacher transceiver 10 (S211).
When the teacher transceiver 10 receives the audio data (S212), the sound output from the earphone 15 is transmitted to the teacher via the amplifier unit 16 (S213).

  In other words, the voice data can be transmitted from the student transceiver 20 as well.
