The audio mixing circuit 150 may be electrically connected to the hearing aid component 110 and the bluetooth component 130 and operatively mixes the hearing aid audio signals with the bluetooth audio signals so that the hearing aid device 100 may be used with both hearing aid functions and bluetooth headset functions. The audio mixing circuit 150 may superimpose the hearing aid audio signal and the bluetooth audio signal so that the user may hear the hearing aid audio signal and the bluetooth audio signal at the same time. In some embodiments, the audio mixing circuit 150 may directly superimpose the hearing aid audio signal and the bluetooth audio signal. In some embodiments, the audio mixing circuit 150 may also process the hearing aid audio signal and the bluetooth audio signal before superimposing them. The processing may be signal amplification processing or signal attenuation processing on the hearing aid audio signal and/or the bluetooth audio signal, so as to adjust the signal strengths of the two audio signals to be relatively balanced, and avoid that one audio signal strength is excessively high to cover the other audio signal. For example, the audio mixing circuit 150 may compare the signal strengths of the hearing aid audio signal and the bluetooth audio signal, and adjust the signal strengths of the two audio signals according to the comparison result. The superposition processing may be linear superposition averaging processing or weighted summation processing.

As shown in fig. 1, the audio mixing circuit 150 may include an op-amp summing circuit 152 and a power amplifier circuit 154. The op-amp summing circuit 152 may be electrically connected to the hearing aid component 110 and the bluetooth component 130 and may be operative to mix the hearing aid audio signal with the bluetooth audio signal.

Speaker 160 may be a bone conduction speaker and/or an air conduction speaker. When the speaker 160 is a bone conduction speaker, the vibration signal generated by the speaker 160 is transmitted to the auditory nerve of the user through the skin and the bone of the user, so that the user can hear the sound; when the speaker 160 is an air-conduction speaker, the sound signal generated by the speaker 160 is transmitted to the auditory nerve of the user through the air and the eardrum, so that the user can hear the sound; alternatively, the speaker 160 may include both a bone conduction speaker and an air conduction speaker, with the speaker 160 generating both the vibration signal and the air conduction sound signal.

The hearing device 100 provided in the present disclosure may be integrated with the bluetooth module 130 based on the hearing aid module 110, and the audio mixing circuit 150 is designed to mix and superimpose the processed hearing aid audio signal and the bluetooth audio signal, so as to output the hearing aid audio signal and the bluetooth audio signal to the speaker 160 for playing.

When the control switch circuit 170 is turned off, the connection between the hearing aid component 110 and the audio mixing circuit 150 is disconnected, and the hearing aid audio signal output from the hearing aid component 110 cannot be input to the audio mixing circuit 150; when the control switch circuit 170 is connected, the hearing aid component 110 is electrically connected to the audio mixing circuit 150, and the hearing aid audio signal output by the hearing aid component 110 may be input to the audio mixing circuit 150. The control switch circuit 170 may be in signal connection with the bluetooth module 130. The bluetooth module 130 may be operable to control the connection and disconnection of the switching circuit 170 based on the first control signal, thereby controlling the connection and disconnection of the hearing aid module 110 and the audio mixing circuit 150.

For example, when the bluetooth connection between the bluetooth module 130 and the electronic device 200 is disconnected and the control switch circuit 170 is connected, the hearing aid device 100 operates in a hearing aid mode to implement a hearing aid function. For another example, when the bluetooth module 130 is connected to the electronic device 200 by bluetooth, and the control switch circuit 170 is turned on, the hearing aid device 100 works in a mixed mode of hearing aid and bluetooth to realize both the hearing aid function and the bluetooth function, and the hearing aid function can be realized while enjoying the bluetooth function, so as to avoid missing important external sound information. For another example, when the bluetooth module 130 and the electronic device 200 are connected by bluetooth and the control switch circuit 170 is turned off, the hearing aid device 100 operates in the bluetooth mode to realize the bluetooth function, and the interference of the external environment is avoided while enjoying the bluetooth function.
