Abstract
The invention discloses a hearing aid with a flexible plug, which is used for solving the problem that the function of the current hearing aid is single. The shell of the hearing aid with the self flexible plug in the invention is provided with a programming hole, a cell cabin, a loudspeaker and a microphone. Each port of a digital signal processor arranged in the shell is respectively connected with the microphone, the loudspeaker and a programming unit. Cells in the cell cabin are connected with the loudspeaker, the digital signal processor and the programming unit. The edge of the lower end of the shell is provided with a U-shaped groove, and a device for flexibly adjusting the electric-wires is installed in the inner part of the U-shaped groove.
Description
Technical field
The present invention is relevant with hearing aids, is a kind of hearing aids that carries flexible plug specifically.
Background technology
Hearing aids is that all help hearing disabilities person to improve dysacousis, and then instrument, unit and the instrument etc. of raising and his conference communicative competence.Hearing aids electric power arranged with two types of non-electricity, the latter goes out of use at present.The former has two kinds of electron tube and transistor types again.The transistor type hearing aids is the dexterousst light, has replaced electron tube and generally employing of quilt after coming out in nineteen fifty.
All in a broad sense various devices that can be effectively import sound into ear can be seen hearing aids as; Say on the narrow sense that hearing aids is exactly an electroacoustic amplifier; The deaf person had been heard originally the sound amplification through it and can not hear clearly, unheard sound, this device is exactly a hearing aids.
The patent No. is that 02245143.9 Chinese utility model patent discloses a kind of digital hearing aid; Programming hole, battery compartment, loud speaker and microphone are arranged on the housing; Each port of digital signal processor in the housing is connected with microphone, loud speaker and programmable device respectively, and the battery in the battery compartment is connected with loud speaker, digital signal processor and programmable device.Comfortable wearing, just with convenient, the compensation hearing loss is effective.Use but can not be inserted on the players such as computer or MP3.
Summary of the invention
The purpose of this invention is to provide that a kind of volume is little, power consumption is little, can be according to the customization of people's ear, wear comfortable, good concealment; Easy to use, function is many, the compensation hearing loss; It is good to listen to comfort level, effectively strengthens the hearing aids that carries flexible plug of listening barrier person speech intelligibilty.
The present invention is the hearing aids that carries flexible plug; Programming hole, battery compartment, loud speaker and microphone are arranged on the housing; Each port of digital signal processor in the housing is connected with microphone, loud speaker and programmable device respectively; Battery in the battery compartment is connected with loud speaker, digital signal processor and programmable device, and it is characterized in that: the housing lower end has the edge to be provided with a U type groove, and there is the electric wire tunable arrangement that stretches U type groove inside.
Said earphone cord is directly connected to the inner audio input end of hearing aids through the flexible tunable arrangement of electric wire, through the U type groove of outer faucal plug cord is derived then and uses, and chamber can be used for storing plug specially.
The flexible tunable arrangement of said electric wire is made up of box body and the coil tension spring, power line, locating clip, Power cord fastener, back-moving spring, the reference column that are arranged in the box body.
Said box body two side correspondence respectively is provided with line outlet, and a line outlet place is provided with locating clip, and corresponding another line outlet box body inboard is provided with electrical wire fastener; The reference column that is provided with below the electrical wire fastener is fixed on the box body; Back-moving spring is inserted in reference column and is attached thereto, and plug cord is around investing coil tension spring and placing in the box body, and earphone cord one end that is connected in hearing aids device mainboard is positioned box body one side by locating clip; Plug stretches out outside the box body through electrical wire fastener, also is provided with the fixing hole that is connected with electrical equipment on the box body.
The preparatory amplifying circuit of series connection successively of the output linking number word signal processor of said microphone; 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; The D/A switch circuit, output attenuatoin circuit, terminating loud speaker.
Said digital signal processor is Toccata chip I TK-100 or CTK-110 or the ToccataPlus chip of Dspfactory.
Said microphone is EM4346 or TM4546 or EK3024; Be connected with the pin (Vreg, Mic, yein) of volume potentiometer and Toccata chip or Toccata Plus chip; Pc case journey device is through the pin (DaiaRx of programming socket (CS44) with Toccata chip or ToccataPlus chip; Dais Tx) connect, loud speaker is that the CLASS-Drcceiver of Knowles is connected with the pin (Rcvt, Dclk, Batt) of Toccata chip or ToccataPlus chip.
Said housing is hard of hearing formula or duct-type or inner ear type or dark duct-type.
The present invention carries telescopic plug; The present invention is through 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, thus the hearing loss of recovering the user better improves its speech intelligibilty.The present invention has fully satisfied the user to listening to comfortable requirement through noise processing circuit harmony feedback inhibition circuit.Whole system of the present invention can be according to patient's ear sized, and all hidden do not have external device in the duct depths, good concealment, comfortable when wearing, and low in energy consumption (operating current uses 13 about 1 milliampere.Zinc-air cell can normally use more than 15 days), do not hinder daily study and work.
