The invention relates to the technical field of electronic equipment, and discloses a microphone switching system in a hearing aid with a wireless transmission function. The microphone switching system comprises a wireless receiving device system, and the system comprises a control port of an audio output level signal, an audio signal output port, a microphone signal input port, a hearing aid signal processing system, a level signal processing unit, a microphone signal switching system and a signal channel switching system, and the system switches signals needing to be processed to be automatically selected into a hearing aid signal channel according to the level signal high-low state of a wireless transmitting device system. The microphone switching system further comprises a microphone connection system, wherein a microphone is connected to both the wireless transmitting device and a hearing aid receiving system. The Bluetooth communication function can be achieved under the condition that one microphone is used, the hearing aid function can also be achieved in the hearing aid state, convenience, conciseness and practicability are achieved, and great convenience is brought to people with weak hearing.
Description
technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a microphone switching system in a hearing aid with wireless transmission function. Background technique [0002] A hearing aid is an electronic device that improves the sound amplification function for the hearing impaired. The existing hearing aids usually only have a separate hearing aid function, and do not incorporate the wireless transmission function into the hearing aid. The microphones of traditional wireless hearing aids are also used separately, and the design concept of the hearing aid itself needs to be smaller. The present invention uses a microphone attached to the wireless receiving device system and the hearing aid signal processing system. On the one hand, it reduces the volume of the design. On the other hand, it is easier to achieve the design concept while reducing the cost. Contents of the invention [0003] In view of the shortcomings of the...
