Background technology
In-the-ear hearing aid is current most popular customized hearing-air, this hearing aids needs according to the duct model of different patient different shell customized. and its outside primary structure is customized shell, panel, internal structure is made up of microphone, digital signal processing chip (band integrated amplifier), receiver, battery, this is a kind of product structure general in the world, advantage be fairly simple, be easy to produce, shortcoming is that the characteristic of sound changes small on physical condition.Mainly connect hearing aids with PC computer at present, changed the electroacoustic index of hearing aids by the parameter of the integrated amplifier regulating digital signal processing chip, this can be called that software adjusts, and uses upper deficiency certain in addition for some specific crowds.In addition, part also can produce Occlusion effect after listening barrier patient wear hearing aid.
Utility model content
The purpose of this utility model is to provide a kind of band physics to lead sound module hearing aids, band physics provided by the utility model leads the intermediate-frequency gain frequency response that sound module hearing aids can strengthen hearing aids, cuts down the impurity of high frequency simultaneously, reduces the acoustic feedback of hearing aids, promotes clearness.
Technical solutions of the utility model are as follows:
A kind of band physics leads sound module hearing aids, this hearing aids comprises customized shell and is covered in the face equipment of customized shell outer openings, described customized shell inside forms acoustic internal chamber, described face equipment comprises panel and is installed on sound collection hole, microphone, circuit board, digital signal processing chip, receiver, the supply unit on panel respectively, this hearing aids also comprise be installed on that being used in acoustic internal chamber transmit voice signal in duct lead sound module, described lead sound module comprise more than one group superpose successively lead sound unit, often group is led sound unit and is comprised ear mold supporting bracket and be installed on phonocatheter in ear mold supporting bracket, the phonocatheter that often group leads sound unit spirals into bending roundabout shape on the ear mold support plate of its correspondence, often group leads the front and back sides that the voice entry of the phonocatheter of sound unit and sound outlet are arranged at this ear mold support plate respectively, last sound outlet of leading the phonocatheter of sound unit docks mutually with a rear adjacent voice entry of leading sound unit, the voice entry of leading the phonocatheter of sound unit near panel side is connected with receiver, the sound outlet of leading the phonocatheter of sound unit away from panel side extends to the duct outlet of customized shell.
Further,
The aperture of the sound outlet part of described phonocatheter is 1.35-1.55mm, is preferably 1.45mm.
Described panel is also provided with the air vent hole penetrating panel.
At least one group of phonocatheter of leading sound unit bends to S type.
Described microphone, circuit board, digital signal processing chip, receiver, supply unit are installed on inside panel respectively, described sound collection hole is arranged at panels outside, and described face equipment also comprises and is installed on panels outside and inwardly penetrates the program switching push button that panel is connected with circuit board.
Described face equipment also comprises and is installed on magnetic induction switch on panel and download program interface.
The operation principle that band physics of the present utility model leads sound module hearing aids is as follows: be made up of several different sound because of each word.Energy contained in language, has 60% to be concentrate on below 500HZ (low frequency), namely more than simple or compound vowel of a Chinese syllable; The concentration of energy of 35% is at 500-1000HZ (medium frequency); Remained by extremely small energy just exist and understand on closely bound up high-frequency sound with voice.So the utility model object is the intermediate-frequency gain frequency response strengthening hearing aids physically by changing the structure leading sound module is connected with receiver inside hearing aids, and cut down the impurity of sound high-frequency signal, reduction hearing aids acoustic feedback, make sonic profile more level and smooth, promote clearness.In addition, be made up of the sound unit of leading that more than a group superposes successively owing to leading sound module, therefore can according to the size of customized shell during design, determine use one group or more than two lead sound unit, thus can need according to patient the peak value regulating hearing aids easily and fast.When use more than two lead sound unit time, only last sound outlet of leading the phonocatheter of sound unit need be docked mutually with a rear adjacent voice entry of leading sound unit.
Compared to prior art, band physics provided by the utility model is led sound module hearing aid instrument and is had the following advantages:
1) band physics provided by the utility model leads that sound module hearing aids can improve the maximum output of hearing aids physically, HF on average exports, hearing aid gain, and the peak value of hearing aids can be regulated to adapt to the condition required for patient.Because the characteristic of peak value is determined by loudspeaker, lead before sound module just can be adjusted to 2000Hz the peak value of hearing aids by this, can allow the intermediate frequency sound of hearing aids sounds abundanter, loudness is larger, speech is more clear like this; And the general peak value of hearing aids of the prior art is all after 2000Hz, and also cannot be adjusted by software, so mixed some and do not reach effect testing.
2) strengthen the intermediate-frequency gain frequency response of hearing aids, cut down the impurity of high frequency simultaneously, reduce the acoustic feedback of hearing aids, promote clearness.
3) panel is also provided with the air vent hole penetrating panel, effectively can avoids the generation of Occlusion effect.
