Abstract
The utility model relates to glasses with a hearing aid for the deaf. In the technical proposal, one side of the glasses legs is provided with a hearing aid system which comprises a microphone (7), a signal amplification circuit board (5), a rechargeable battery (9), a charging jack (10), a micro electromagnetic sound transmitter (11) and the like. The glasses are characterized in that the sound uttered by the micro electromagnetic sound transmitter (11) is transmitted to the auditory canal of the user through a soft, delicate and curved acoustic hose (12), thereby achieving the function of the hearing aid for the deaf. The utility model satisfies the comprehensive requirements of people for the hearing aid with the beauty, applicability, concealment, comfort and convenience to some extent, and has certain values for promotion and application.
Description
Technical field
The utility model relates to extraordinary manufacturing glasses field, especially about a kind of glasses that the hidden deaf-aid set is installed in the mirror leg.
Background technology
Commercial osophone has polytype and styles such as boxlike, hard of hearing formula, duct-type on existing osophone market, but the hearing aid glasses that osophone is installed in the mirror leg were seen in the market sale product more.Chinese patent 92204338.8, name is called spectacle frame formula osophone and discloses and a kind of deaf-aid set is installed in technical scheme in the leg of spectacles, the simple structure practicality, but these designs all be unable to do without the traditional insert earphone of use fills in hearing aid mode in the ear, this traditional hearing aid mode is not only wanted to use osophone not hear sound but also is wanted to keep the comfortable clog-free sense of duct for those, and keep the attractive in appearance of ear outside, the hidden consumer of receiver is unsatisfactory, if use dark duct-type Mini-otophone of ensconcing in the duct to cost an arm and a leg again, the battery short shortcoming of changing battery trouble service time, the existence of these present situations has directly influenced the convenience that the consumer uses.
Summary of the invention
In order to overcome above defective, the purpose of this utility model is to provide a kind of glasses with deaf-aid set, the comfortableness that kept again in the sound clearly in user's duct and the aesthetic property and the sound conduction disguise of ear's outward appearance can be provided the wearer to deafness, the convenience that battery uses satisfies hard of hearing person on can being implemented in to greatest extent and requires the request for utilization that reaches.
The technical solution of the utility model realizes in the following manner: a kind of glasses with deaf-aid set, the hearing assistance system of being made up of microphone, signal amplification circuit plate, rechargeable battery and charging socket, micro electromagnetic acoustical generator etc. has been installed in a side of mirror leg, the sound that sends in the micro electromagnetic acoustical generator extends in user's the duct via acoustic conductance flexible pipe soft, very thin bending, realizes the hearing aid effect to the aurally handicapped.
Above-mentioned signal amplification circuit plate is made up of discrete electronic component circuit, special-purpose integrated hearing aid chip circuit or DAB sound circuit, discrete electronic devices and components are made pre-amplifier, the audio output circuit of integrated amplifier chip manufacturing, after triode amplifies, deliver to the integrated amplifier chip by the voice signal of microphone induction and carry out power amplification output, be transmitted in user's duct by the acoustic conductance flexible pipe after the vibration of drive micro electromagnetic acoustical generator is sounded, volume is regulated by volume adjustment knob.
Above-mentioned acoustic conductance flexible pipe is a silicon rubber.
The utility model has satisfied attractive in appearance, suitable, hidden, comfortable, the easily composite request of people to the osophone product to a certain extent, has certain application value.
Description of drawings
Fig. 1 is a cut-open view of the present utility model.
Fig. 2 is an electrical schematic diagram of the present utility model.
Fig. 3 is a micro electromagnetic acoustical generator sound conduction synoptic diagram of the present utility model.
Embodiment
Know by Fig. 1, the glasses of present embodiment band osophone comprise that picture frame 1, left and right sides eyeglass 2, left mirror leg 3, right mirror leg 4, signal amplification circuit plate 5, volume adjustment knob 6, microphone 7, power switch 8, rechargeable battery 9, charging socket 10, electromagnetic tone generator 11, acoustic conductance flexible pipe 12 form, above-mentioned components and parts are assembled in the mirror leg on the left side of glasses or right side, form complete, a hidden hearing assistance system.Signal amplification circuit plate 5 can use the discrete electronic component circuit of known technology, special-purpose integrated hearing aid chip circuit or DAB sound circuit to make, the utility model has adopted discrete component to make pre-amplifier for being fit to mass consumption, the audio output circuit that integrated amplifier chip DA2822 makes has that output power is big, tonequality good, can satisfy the deaf serious advantage that the people uses, cost is low.
Know by Fig. 2, it is the osophone electrical schematic diagram, after triode 9014 amplifies, deliver to DA2822 by the voice signal of microphone 7 inductions and carry out power amplification output, be transmitted in user's duct by acoustic conductance flexible pipe 12 after 11 vibrations of drive electromagnetic tone generator are sounded, volume is regulated by volume adjustment knob 6.
Being known by Fig. 3, is electromagnetic tone generator sound conduction synoptic diagram, and principle of work is with common insert earphone, be made up of superpower magnet steel and the coil and the vibrating diaphragm that are wrapped on the framework, difference is to adaptation is installed on the mirror holder, making frivolous especially, thickness is 3-4mm only, diameter of phi 10mm.The acoustic conductance flexible pipe uses silastic material to make, soft high resilience, and outer dia Φ 3mm, interior through Φ 2mm, length can be chosen according to individual demand.Osophone rechargeable battery 9 adopts the 3.7V lithium battery power supply, for the method maintenance electric power that the work and rest custom that is fit to people is taked to work by day and charged night, has removed the trouble that the user often changes battery from.
Eyeglass 2 can be prepared arbitrarily according to individual demand by the user, such as using presbyopic, myopia, zero diopter, asymptotic, polarized lenses all can.The utility model has satisfied attractive in appearance, suitable, hidden, comfortable, the easily composite request of people to the osophone product to a certain extent, has certain application value.
