Abstract
The utility model relates to an earplug type bone-conduction voice receiver. An alnico (4) is provided in a shell (1), a coil (5) encircles the alnico (4) and is connected with an input line (9), a soft magnetic body (6) is arranged on the upper end of the alnico (4) via an elastic sheet (7), and an oscillator (8) is fixed on the soft magnetic body (6). The utility model can directly convert voice information into mechanical vibration that acts on the ear canal, and is contacted with the part nearing the cochlea in the skull to directly transmit the vibration information of the voice information to the auditory nerve, and therefore a person with hearing difficulty can relatively clearly hear the voice information.
Description
The utility model relates to a kind of ear type bone-conduction receiver, belongs to electroacoustic transducer manufacturing technology field.
Along with the arrival with the information age of improving constantly of people's quality of life, the ear handicapped person exchanges the raising of quality with the people, with social information, has become the important component part that this crowd's life, work quality improve.What can help at present that the residual people of ear improves one's hearing is inner ear type conductance receiver, and it mainly remedies the reduction of ear-drum ability to accept by improving sound level.But because its sensitivity is always limited, thus no ear-drum person is acted on not quite, to wearing out because of older ear-drum, the old of high frequency attenuation, tend to because of low frequency is heavy, reduced definition and run counter to desire, most of hearing decay person joins reason that hearing aids is reluctant again to be used always that Here it is.
The purpose of this utility model is to design a kind of ear type bone-conduction receiver, language message can be converted into the duct that mechanical oscillation act on the people, the position that is bordering on people's cochlea contacts with connecting in the skull, the vibration signal of language message is directly passed auditory nerve in the people, thereby make hearing decay person hear acoustic information relatively clearly.
Design of the present utility model: a kind of ear type bone-conduction receiver, be provided with magnet steel (4) in the shell (1), be wound with coil (5) on the magnet steel (4), and coil (5) joins with incoming line (9), soft magnetic bodies (6) is arranged on the upper end of magnet steel (4) by flexure strip (7), is fixed with ticker (8) on the soft magnetic bodies (6).
The top perk left of ticker (8), its shape and people's duct matches.Flexure strip (7) is an annular.Coil (5) joins by terminal block (10) and incoming line (9).Shell (1) is made of protecgulum (2), housing (3) and bonnet (11), and protecgulum (2) is positioned at the upper end of housing (3), and bonnet (11) is positioned at the lower end of housing (3).
Advantage that the utility model compared with prior art has and effect:
1, because the utility model can be converted into language message the duct that mechanical oscillation act on the people, the position that is bordering on people's cochlea contacts with connecting in the skull, the vibration signal of language message is directly passed auditory nerve in the people, thereby make hearing decay person hear acoustic information relatively clearly.It is hands-free to be used for mobile phone, has solved the problem that the residual person of ear uses mobile phone to communicate.
2, the utlity model has good high frequency response, be used for hearing aids, can solve the residual person of ear excessive worry of noise when using common hearing aids.
3, the utility model person that is particularly suitable for not having the ear-drum uses, through testing its result of use far above inner ear type conductance receiver.
Fig. 1 is a structural representation of the present utility model.
1 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.
A kind of ear type bone-conduction receiver, be provided with magnet steel (4) in the shell (1), be wound with coil (5) on the magnet steel (4), and coil (5) joins with incoming line (9), soft magnetic bodies (6) is arranged on the upper end of magnet steel (4) by flexure strip (7), is fixed with ticker (8) on the soft magnetic bodies (6).The top perk left of ticker (8), its shape and people's duct matches.Flexure strip (7) is an annular.Coil (5) joins by terminal block (10) and incoming line (9).Shell (1) is made of protecgulum (2), housing (3) and bonnet (11), and protecgulum (2) is positioned at the upper end of housing (3), and bonnet (11) is positioned at the lower end of housing (3).
Operation principle: when passing through the alternating current of incoming line input language signal in the coil, the polar form of magnet steel will change along with the variation of alternating current direction, soft magnetic bodies is by the poles attract of alternation or push away and put, ticker is vibrated thereupon, and its vibration frequency is identical with the frequency of speech signal, and amplitude is directly proportional with the amplitude of speech signal.Thereby the vibration signal of language message is directly passed auditory nerve in the people, make hearing decay person hear acoustic information relatively clearly.As long as be inserted into duct during use, rotation direction gets final product its perk position, ticker top behind brain.
