The hearing-aid device comprises a microphone, a first capacitor and a second capacitor, wherein a positive electrode end of the microphone is connected to a first resistor, and a negative electrode end of the microphone is connected to a negative electrode of a power supply; the first resistor is connected to an earphone jack, and the earphone jack is connected to a positive electrode of the power supply; the first capacitor is connected to a common end of the microphone and the first resistor, a second end of the first capacitor is connected to a second resistor, the second resistor is connected to a first end of an adjustable resistor, a second end of the adjustable resistor is connected to an input end of a COMS amplifier, an output end of the COMS amplifier is connected to a sliding end of the adjustable resistor through the third resistor; the first end of the second capacitor is connected to the output end of the COMS amplifier, the second end of the second capacitor is connected to a base electrode of a PNP transistor, a collector of the PNP transistor is connected to the positive electrode of the power supply, and an emitter of the PNP transistor is connected to the negative electrode of the power supply and connected to the base electrode thereof through a fourth resistor.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a hearing aid device. Background technique [0002] Existing hearing aids are expensive, bulky, and power-consuming. It is very inconvenient for the elderly to turn on the switch to aid hearing. [0003] The large size of the hearing aid device is mainly determined by the power supply. The power conversion efficiency of the power supply is low, which must be compensated by the battery capacity. How to improve the power conversion efficiency of the power supply, reduce the battery volume, and then reduce the overall volume of the hearing aid device. Enhancing the user's wearing experience is an urgent problem to be solved at present. Contents of the invention [0004] The invention provides a hearing aid device, which solves the problems of high price, large volume and power consumption of the existing hearing aid device. [0005] Technical scheme of the present invention ...
