Description
technical field [0001] The present invention relates to the field of electronic technology, in particular to a hearing aid device. Background technique [0002] The existing hearing aid device is expensive, bulky, and consumes electricity. When the elderly use it, the switch needs to be turned on for hearing aid, which is very inconvenient. [0003] The large size of the hearing aid device is mainly determined by the power source. The power conversion efficiency of the power source is low, which must be compensated by the battery capacity. How to improve the power conversion efficiency of the power source, reduce the battery size, and then reduce the overall size of the hearing aid device, Enhancing the user's wearing experience is an urgent problem to be solved at present. SUMMARY OF THE INVENTION [0004] The present invention provides a hearing aid device, which solves the problems of high price, large volume and power consumption of the existing hearing aid device. ...
