Embodiment Construction

[0029] Below in conjunction with accompanying drawing, the technical scheme of invention is described in detail: figure 1 A binaural hearing aid device used in conjunction with a Bluetooth headset is shown. The invention collects the sound of the external environment, and after a series of audio processing such as noise reduction processing, differential signal processing, and independent two-channel power amplification, the audio signal is sent out through Bluetooth technology. After being used with a commercially available stereo bluetooth headset (8), the function of binaural hearing aid can be realized.

[0030] When using the present invention for the first time, the user needs to pair it with the stereo bluetooth earphone (8). First turn on the power switch, the power indicator LED on the fuselage will light up and display the approximate power status, and the LED pairing indicator will flash, indicating that it is not currently paired. The user sets the commercially a...

Abstract

The invention relates to a binaural hearing-aid device cooperating with a Bluetooth earphone for use. A sound pickup module (1) collects environment sound and transmits the environment sound to an audio signal processing module (2), and the audio signal processing module (2) sequentially carries out noise reduction and differential signal processing of audio signals. A two-channel power amplification module (3) amplifies a left-channel differential signal and a right-channel differential signal. The two-channel power amplification module (3) is connected with an audio input end of a Bluetooth SRC audio signal source module (4). The Bluetooth SRC audio signal source module (4) serves as Piconet main equipment, searches a stereophonic Bluetooth earphone (8) within the range of 10m, and achieves default building of wireless audio data connection of an ACL asynchronous link. The amplified left-channel and right-channel differential signals are transmitted to the stereophonic Bluetooth earphone (8) for playing, thereby achieving the binaural hearing aid.

Description

technical field [0001] The invention relates to a binaural hearing aid device used in conjunction with a bluetooth earphone, belonging to the technical field of hearing aids. Background technique [0002] The decline of hearing function in the elderly is a common phenomenon, and it increases year by year with age. Generally, electronic hearing aids can be used for those who are ineffective in drug treatment. It is a small loudspeaker device for the hearing-impaired to compensate for hearing loss. Since 1878, American scientist Bell invented the first carbon hearing aid. Hearing aids have been continuously improved and designed for more than 100 years. Today, the most popular types are box type, glasses type, behind-the-ear type, customized type, hidden type, open type, standard ear canal and other types. [0003] Among them, box-type hearing aids are mostly used by children and the elderly. This type of hearing aid has a large volume and can be equipped with multiple funct...
