Abstract
The utility model relates to a digital BTE (behind-the-ear) aid, which comprises a BTE type main body and an externally-connected receiver which are connected through a metal conducting wire, a hearing aid chip, a microphone, an induction coil, a program switching button, a programming interface, a circuit board and a battery compartment are arranged in the BTE type main body, and the externally-connected receiver comprises a receiver, a receiver protection cavity, an externally-connected receiver earplug or an externally-connected receiver housing. The microphone of the hearing aid and the receiver are arranged in different cavities, the microphone of the BTE type hearing aid is arranged in the BTE type main body, while the receiver is arranged in the auditory meatus of a patient, and thedistance between the microphone of the hearing aid and the receiver is enlarged, thereby eliminating acoustical feedback; at the same time, since the microphone of the hearing aid and the receiver are separated, the volume of the BTE type main body of the hearing aid is reduced.
Description
Technical field
The utility model relates to a kind of digital ear-level hearing aid, especially a kind of the hearing aids receiver is separated with hard of hearing formula casing, and receiver is positioned at the ear-level hearing aid of duct, is applicable to that hearing loss is heavy, simultaneously to the demanding user of the aesthetics of hearing aids.
Background technology
At present the hearing aids of listening the barrier patient to use always of China has three kinds: the boxlike hearing aids, hard of hearing be hearing aids and customized type hearing aids.
Boxlike machine profile is as the rectangle box of a matchbox size, and the microphone of hearing aids, amplifier and battery pack are mounted in it, and the outside connects earphone and earplug by a long lead.This type of hearing aids volume is bigger, be generally used for the movable inconvenient people of the elderly or finger, but volume is big, disguise is poor, lead is fragile, big, the easily distortion of this bulk noise.
The duroplasts tack that ear-level hearing aid depends on a crooked semicircular in shape is hung on the hearing aids behind the ear, and microphone, amplifier and receiver all are embedded in machine intimate.Though the ear-level hearing aid gain is big, the hard of hearing formula main body that has comprised all parts accordingly also can be bigger.If use skeleton ear mold or general button, common powerful hearing aids volume can only reach about 1/3, otherwise will cause and utter long and high-pitched sounds, and uses the good plain edition ear mold of sealing, again can be more vexed, wear uncomfortable.
The customized type hearing aids is to make according to patient's concha auriculae and external auditory meatus shape, is most widely used in the world at present hearing aids type.Though it is littler on the volume than ear-level hearing aid; but also just because the restriction of volume causes the performance of hearing aids not too complete; and power also can be less relatively; can't satisfy severe hearing loss patient's hearing compensation; in addition the duct-type hearing aids cause easily the user stifled ear effect (stifled ear effect is meant: after cavity of concha or external auditory canal opening are stopped up by ear mold or hearing aids shell, the hearing aids wearer feel own voice like the echo sample or sound that sensation is dull and natural).
No matter existing hearing aids product is hard of hearing machine or customization machine, electronic unit all is in the cavity, under the normal condition, the sound that hearing aids is accepted is into from the outside delivered to the receiver sounding after amplifying, and being the mode of a part by acoustic propagation of receiver acoustic energy, the acoustic feedback phenomenon passes to microphone, the phenomenon of uttering long and high-pitched sounds of being amplified by microphone again and causing, so microphone of hearing aids, receiver distance between the two is very big to the feedback influence of hearing aids, the volume that is also limiting to hearing aids, therefore present hearing aids can't be in aesthetic in appearance and function, comfort level reaches perfect unification.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art and provide a kind of two advantage---ear-level hearing aids of external receiver in conjunction with hard of hearing formula and customized type hearing aids, this hearing aids can avoid acoustic feedback, comfortable wearing, stifled ear effect, tonequality good; Be high-power performance and wear the aesthetics perfect adaptation.
The technical scheme in the invention for solving the above technical problem is: this numeral ear-level hearing aid; comprise hard of hearing formula main body and external receiver; hard of hearing formula main body is connected by plain conductor with external receiver; be provided with hearing aids chip, microphone, inductance coil, program switching push button, DLL (dynamic link library), wiring board and battery compartment in the hard of hearing formula main body, external receiver comprises receiver, receiver protection chamber, external receiver earplug or external receiver shell.With in receiver is divided into different cavitys, the microphone of described ear-level hearing aid places in the hard of hearing formula main body with the microphone of hearing aids, and receiver is placed on patient's duct, has widened the distance between hearing aid microphone and the receiver, eliminates acoustic feedback; Because the microphone of hearing aids separates with receiver, cause the smaller volume of the hard of hearing formula main body of hearing aids simultaneously.
Microphone described in the utility model, plain conductor interface, program switching push button and DLL (dynamic link library) are connected with the hearing aids chip respectively, and hearing aids chip one side is provided with inductance coil, and the hearing aids chip is fixing in the circuit board with inductance coil.
Receiver described in the utility model is outside equipped with one deck receiver protection chamber, and plain conductor is arranged in the sebific duct, and receiver links to each other with plain conductor interface on the hard of hearing formula main body by plain conductor.
The utility model compared with prior art has following beneficial effect: (1) places microphone and receiver respectively in the hard of hearing formula main body behind the ear and in the duct, because each has lacked parts, therefore volume dimerous all has dwindling clearly, does not have ear mold, and disguise is better.(2) receiver is transferred to the outside from hard of hearing machine main body, be placed in user's duct with open earplug or customized type shell, so just increased the distance between microphone and the receiver, can effectively suppress acoustic feedback, increase actual gain, especially high-frequency gain.(3) selectivity flexibly: can select corresponding open earplug for the ear canal shapes that different patients are different, perhaps select open customized shell according to needs of patients, open earplug is highly suitable for falling suddenly the light moderate hearing loss crowd of type hearing, can effectively suppress stifled ear effect and acoustic feedback, and the customized type ear mold is applicable to the crowd that hearing loss is heavier.(4) connected system of the uniqueness of external receiver can make the frequency response of hearing aids obtain optimization, obtains level and smooth output frequency response curve, makes the frequency compensation scope wideer, improves tonequality; Reduce stifled ear effect simultaneously.(5) plain conductor that is used to connect between main body fuselage and receiver can be divided into multiple length and flexibility specification according to the ear size, to adapt to different patients' needs.
