Problems solved by technology

[0004] However, the above-mentioned technical solution only provides automatic switching between the function mode and the sleep mode. In many cases, the user needs to set some parameters of the hearing aid, such as volume, tone, etc., and this technical solution is powerless; There is no display of the set parameters, and the user cannot clearly understand the working status of the hearing aid

Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] Please refer to figure 1 As shown, the hearing aid of the present invention includes a main controller MCU, a sound signal amplifier connected to the MCU, a volume adjustment module, a tone adjustment module, an LCD display module, a membrane switch and a power supply module.

[0024] The main controller MCU is used to complete the conversion between the sound signal and the electrical signal, the switch between the use mode and the setting mode, and the setting and display of the parameters. It has 4KB flash memory FLASH, 256B SRAM, 256B electrical Erasable read-only memory EEPROM, 12 channels of 10-bit analog / digital A / D channels, two 8-bit timer counters, and one 16-bit timer counter. please combine figure 2 As shown, the main controller MCU includes a chip U11, a capacitor C32, and a resistor R35.

[0025] The sound signal amplifier is used to amplify ...

Abstract

The invention provides a hearing aid which comprises a main control unit (MCU) used for finishing the transformation between aural signals and electric signals, and the switch between a use-mode and a set-mode, and setting up and displaying parameters, an aural signal amplifier used for amplifying collected sound, a volume regulating module used for regulating the volume of a left and a right sound channels respectively, a pitch regulating module used for regulating the pitch of the left and the right sound channels respectively, an LCD displaying module used for displaying the working state of the hearing aid and parameters, a thin-film switch and a power module used for supplying power. The aural signal amplifier, the volume regulating module, the pitch regulating module, the LCD displaying module, the thin-film switch and the power module are respectively connected with the MCU. The hearing aid of the invention provides the function of switch between the use-mode and the set-mode, thus leading the use to be more convenient for users. In addition, the hearing aid displays the set parameters, thereby being beneficial to knowing the working state of the hearing aid more clearly by the users.

Description

technical field [0001] The invention relates to a hearing aid and a control method thereof. Background technique [0002] A hearing aid (Hearing Aid) is a small amplifying device used by the deaf to compensate for hearing loss. It usually includes a microphone (microphone or microphone) for receiving sound and converting it into an electrical signal, and a microphone for amplifying the electrical signal. An amplifier, earphones (receivers) for converting electrical signals into acoustic signals, and a power supply. With the development of technology, hearing aids are endowed with more and more functions, and their performance is gradually improving and improving. [0003] In Chinese invention patent application No. 200510065844.5 published on October 19, 2005, a hearing aid that can automatically switch between a full-function mode and a sleep mode according to the location of the hearing aid is disclosed. The hearing aid includes a hearing aid module for processing an inp...
