Description
Technical field
The present invention relates to a kind of auditory prosthesis.
Background technology
Existing hearing aids is made up of microphone, Microspeaker and sound signal processing circuit, battery etc.Due to the reason of people's ear load, it is too huge that hearing aids can not do, otherwise people's ear can't bear the heavy load, on the other hand, hearing aids do large a little a bit, also just may cause to wearer and wear discrimination, so existing hearing aid apparatus do all as far as possible little, the ability which limits its signal processing system can not be too strong, and high-end metal-air cell also selected by battery, energy consumption can not be too high, and such compromise makes this hearing aid effect very limited, often occur that noise is serious, the problems such as sense of hearing distortion.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of auditory prosthesis, easy to use, effectively improves hearing aid effect.
Realize the technical scheme of the object of the invention:
A kind of auditory prosthesis, comprises microphone, Microspeaker and sound signal processing circuit, it is characterized in that: microphone and Microspeaker composition earphone, be provided with separate cavities between microphone and Microspeaker; Also comprise hearing aid terminal, sound signal processing circuit is arranged in hearing aid terminal, and the signal output part of microphone connects the signal input part of sound signal processing circuit through ADC module, and the signal output part of sound signal processing circuit connects micro-letter loud speaker through DAC module.
Said hearing aid terminal can be mobile phone.
Sound measurement module is provided with between sound signal processing circuit and DAC module.
Sound signal processing circuit, ADC module, DAC module, sound measurement module are all positioned at hearing aid terminal, hearing aid terminal and earphone wired connection.
Sound signal processing circuit, sound measurement module are positioned at hearing aid terminal, and ADC module, DAC module are arranged on earphone, hearing aid terminal and earphone wireless connections, and earphone and hearing aid terminal are equipped with wireless sending module and wireless receiving module.
On earphone, the encoded module of signal output part of ADC module connects wireless sending module, and the signal output part of wireless receiving module connects DAC module through decoder module; In hearing aid terminal, the signal output part of wireless receiving module connects sound signal processing circuit, and the signal output part of sound signal processing circuit connects wireless sending module through sound measurement module.
The beneficial effect that the present invention has:
The present invention, by microphone and Microspeaker composition earphone forms, conveniently wears use, effectively prevent and wear discrimination.Sound signal processing circuit, due to by microphone and Microspeaker composition earphone, can be separately set in hearing aid terminal, have stronger sound processing capabilities, obtain better hearing aid effect by the present invention.Sound measurement module is provided with between sound signal processing circuit of the present invention and DAC module, when user uses first, this module plays the reference signal of the different loudness of different frequency by earphone, carry out the Listening Ability of Ethnic curve of test subscriber's ear, in follow-up hearing aid process, just can carry out hearing compensation by this Listening Ability of Ethnic curve, obtain better hearing aid and experience.Hearing aid terminal of the present invention can realize wired or wireless connection with earphone, further facilitates use.Hearing aid terminal of the present invention can be mobile phone, by sound signal processing circuit, ADC module, DAC module, sound measurement module installation in mobile phone, realizes a tractor serves several purposes, easy to use.
Accompanying drawing explanation
