Abstract
The utility model relates to a full digital hearing-aid. A shell body (1) is provided with programming holes (2), a battery chamber (3), a loudspeaker (4) and a microphone (5), and each port of a digital signal processor (6) arranged inside the shell body is respectively connected with the microphone (5), the loudspeaker (4) and a programmer, wherein a battery arranged inside the battery is connected with the loudspeaker (4), the digital signal processor (6) and the programmer. The utility model has the advantages of comfortable wearing, convenient use and favorable effect of hearing loss compensation.
Description
Technical field:
The utility model is relevant with hearing aids.
Background technology:
At present, hearing aids miscellaneous is arranged on the market, but be analog hearing aids mostly, analog hearing aids has following shortcoming:
The traditional analog hearing aids uses linear amplifier circuit usually, even some high-grade hearing aids provides non-linear enlarging function, but because technical limitations makes the user of some local hearing serious defects use hearing aids can not obtain gratifying effect.
The traditional analog hearing aids has static noise, is quietly making the people uncomfortable in the environment.
Though traditional hearing aid also has very high sensitivity, in noisy environment, do not hear the other side's one's voice in speech.
Voice environment varies, and when voice environment changes, easily makes external drive saturated, and at this moment hearing aids can generation makes us insufferable and utters long and high-pitched sounds.
Power consumption is big, and battery life is short.Disguised poor, wear uncomfortable.
The content of utility model:
The purpose of this utility model provides that a kind of volume is very little, power consumption is little, can be according to the customization of people's ear, wear comfortable, good concealment, easy to use, the compensation hearing loss, it is good to listen to comfort level, effectively strengthens the digital hearing aid of listening barrier person speech intelligibilty.
The utility model is a digital hearing aid, programming hole (2), battery compartment (3), loud speaker (4) and microphone (5) are arranged on the housing (1), each port of digital signal processor (6) in the housing is connected with programmable device with microphone (5), loud speaker (4) respectively, and the battery in the battery compartment is connected with programmable device with loud speaker (4), digital signal processor (6).
The pre-amplifying circuit of series connection successively of the output linking number word signal processor (6) of the utility model microphone (5), mould/number conversion circuit, time domain/frequency domain change-over circuit, wide dynamic range compression processing circuit, noise processing circuit, frequency response control circuit, frequency time domain treatment circuit, frequency domain/time domain change-over circuit, D/A switch circuit, output attenuatoin circuit, terminating loud speaker (4).
The utility model digital signal processor (6) is Toccata chip I TK-100 or CTK-110 or the Toccata Plus chip of Dspfactory.
The utility model microphone (5) is EM4346 or TM4546 or EK3024, be connected with the pin (Vreg, Mic, ycin) of volume potentiometer (10) and Toccata chip or Toccata Plus chip, the PC programmable device is by the pin (DaiaRx of programming socket (CS44) with Toccata chip or ToccataPlus chip, Daia Tx) connect, loud speaker (4) is that the CLASS-Dreceiver of Knowles is connected with the pin (Rcvt, Dclk, Batt) of Toccata chip or Toccata Plus chip.
The utility model housing (1) is hard of hearing formula or duct-type or inner ear type or dark duct-type.
The utility model is by meticulous frequency response control of 16 wave bands and channel width dynamic range compression Characteristics Control, the person's that can good coupling listens to the barrier hearing loss situation, fully hearing is tested the requirement of joining, thereby the hearing loss of recovering the user better improves its speech intelligibilty.The utility model has fully satisfied the user to listening to comfortable requirement by noise processing circuit harmony feedback inhibition circuit.The utility model whole system can be according to the customization of patient's ear size, all hidden in the duct depths, there is not external device, good concealment, comfortable when wearing, and low in energy consumption (operating current is about 1 milliampere, use the 13# zinc-air cell normally to use more than 15 days), do not hinder daily study and work.

Embodiment:
The utility model is by shell, the EM4346 of Knowles company or TM4546 or EK3024 microphone, the CLASS-D loud speaker of Knowles company, the Toccata ITK-100 of Dspfactory company or CTK-110 digital signal processor, volume knob, battery compartment, the programmable device interface is formed.Wide dynamic range compression processing, noise treatment, frequency response control are finished by digital signal processor, and the user wears the sound that can hear after the processing, to reach the purpose of part or all of recovery normal good hearing.
Sound around the microphone collection, an A/D converter transfers the voice signal that collects to digital signal, finishing the wide dynamic range compression by digital signal processor then handles, frequency response control, noise reduction process, behind automatic gain control etc., the process D/A switch,, import patient Er Nei into through loud speaker output.
