Multi-channel hearing aid device

Abstract

The invention discloses a multi-channel hearing aid device. The device comprises an earphone and a main body connected with the earphone, the main body comprises a sound input module, a controller, aDSP chip and a sound output module. The DSP chip comprises a left channel DSP and a right channel DSP. The sound output module comprises a left channel output module and a right channel output module;the sound input module comprises a microphone array input module, the microphone array input module is connected with the left channel DSP and the right channel DSP, the left channel DSP is connectedwith the left channel output module, the right channel DSP is connected with the right channel output module, and the left channel output module and the right channel output module are both connectedwith the earphone. According to the multichannel hearing aid device, the advantage of large internal space of a box type hearing aid is effectively utilized, the defects of sound collection and DSP systems of various hearing aids are overcome, the form of sound collected by the left ear and the right ear of a human body is effectively simulated, and the listening effect in a noise environment isgreatly improved.

Description

technical field [0001] The invention relates to the field of hearing aids, in particular to a multi-channel hearing aid device. Background technique [0002] Usually, the hearing aid has only one microphone system, which is responsible for collecting sound; there is also a speaker speaker system, which is responsible for outputting the sound amplified by the DSP circuit of the hearing aid, for deaf users to compensate for hearing and listen. This design is very convenient to use, but the hearing aid effect is not good. In addition to the poor sound processing effect caused by the circuit design of the hearing aid, another important reason is the single ear hearing aid. Most cases of deafness are hearing loss in both ears, and the hearing effect of both ears is better than that of one ear, even for people with normal hearing. Due to the defects of single-ear hearing aids of box hearing aids, this economical and applicable hearing aid method is being replaced by expensive ea...

Problems solved by technology

These two kinds of hearing aids are made smaller and smaller, because people with hearing impairment are not willing to let others know their hearing defects. In order to achieve the most beautiful appearance, manufacturers blindly change small hearing aids. The number and location of microphones are limited, so modern hearing aids are often not effective in noisy environments

At present, many manufacturers try to improve the listening effect by developing new DSP systems, but the problem not only has no obvious breakthrough, but also causes the price of hearing aids to be expensive, which makes it unaffordable for a large number of hearing-impaired people, and finally chooses to give up wearing hearing aids.

However, if you choose a low-priced behind-the-ear or ear canal hearing aid, the listening effect will be poor, and it will be more difficult for users to accept it.
