Abstract
The invention relates to an electromagnetic type bone conduction telephone receiver which comprises a shell (1) and a cover (2); a lower pole shoe (3) is fixed in the shell (1) and is provided with magnetic steel (4) and a coil (5); an upper pole shoe (6) is fixed on a vibration sheet (7) and arranged above the magnetic steel (4); and the vibration sheet (7) is fixed on the shell (1). In the invention, the sound can be conducted by using the property that human bones can conduct sound to conduct sound; when in use, the telephone receiver is put on cheekbones in front of ears so that the wholeears can be exposed to an environmental sound field; and sound signals sent by communication equipment are converted by the telephone receiver into mechanical vibration signals which are directly transmitted into human skulls, and then to cochlea and finally to human brains; in such a way, human eardrums are directly exposed to the environmental sound field and receive information transmitted by air vibration at all times, while communication information is transmitted by the skulls, thereby achieving the transmission of both the environmental information and the communication information.
Description
Technical field
The present invention relates to a kind of electromagnetic type bone conduction telephone receiver.
Background technology
The receiver that is used for various communication equipments at present is air-conduction type, promptly by air transmitted acoustic pressure is acted on acceptor's the ear-drum, and by ear bones, the cochlea of ear-drum by the people, sound imports people's brain into the most at last.The subject matter of air-conduction type receiver is: it must be buckled on the auricle (earphone) during use or get lodged in duct mouth (earplug), like this, when the people puts on earphone or earplug, just can not listen attentively to effectively, analyze acoustic information, make some should hear that the service condition that must understand environmental information of living in again from the communication equipment voice signal can not satisfy from surrounding environment.
Summary of the invention
The technical problem that the present invention solves: design a kind of electromagnetic type bone conduction telephone receiver, utilize skeleton that the transport properties of sound is carried out sound conduction.During use receiver is placed on the cheekbone of people's ear the place ahead, allow people's ear all be exposed in the environment sound field, the acoustical signal that communication equipment sent is converted into mechanical oscillation signal by receiver and directly passes skull in the people, imports cochlea into by skull and enters brain then.People's ear-drum is directly exposed in the environment sound field like this, the information of accepting air vibration at any time and being transmitted, and the communication information has solved the problem that communication and environmental information are neglected neither then by the skull transmission.
Technical solution of the present invention: a kind of electromagnetic type bone conduction telephone receiver, comprise housing (1) and lid (2), housing (1) internal fixation has following pole shoe (3), magnet steel (4) and coil (5) are housed on the following pole shoe (3), last pole shoe (6) is fixed on the vibrating reed (7), and making pole shoe (6) be positioned at the top of magnet steel (4), vibrating reed (7) is fixed on the housing (1).
Described pole shoe (3) down is fixed on the bottom of housing (1), and coil (5) is on following pole shoe (3), and magnet steel (4) is sleeved on the coil (5).
Be shaped on pillar (8) in the described housing (1), vibrating reed (7) is fixed on the upper end of pillar (8).
Be shaped on line hole (9) on the described housing (1).
Advantage that the present invention compared with prior art has and effect:
1, the technical indicator that reaches:
A. impedance: 600 ± 30% Ω (1000Hz).
B. frequency sweep sensitivity: 〉=78dB/ref 1 μ N (200Hz～4000Hz).
C. in frequency response: 200Hz～4000Hz scope, frequency response curve should meet the shape of product standard defined, and resonance frequency should be in the scope of 900Hz ± 15%.
D. rated power: 10mW.
E. the limit is not damaged power: 100mW.
2, result of use: the present invention is used for the bone conduction formula electrophone group of our company, through repeatedly with the communication equipment joint-trial, communication effect is preferable, and can liberate user's ears, make it can pick up other acoustic informations in the environment, solved the problem that communication and environmental information are neglected neither.
3, the present invention adopts all-sealed structure, and is waterproof, dustproof, anti-salt fog.Ability with good anti-adverse environment.

Embodiment:
1,2,3,4,5 a kind of embodiment of the present invention is described in conjunction with the accompanying drawings.
A kind of electromagnetic type bone conduction telephone receiver comprises housing (1) and lid (2), and following pole shoe (3) is fixed on the bottom of housing (1), and coil (5) is on following pole shoe (3), and magnet steel (4) is sleeved on the coil (5).Be shaped on pillar (8) in the housing (1), vibrating reed (7) is fixed on the upper end of pillar (8).Last pole shoe (6) is fixed on the vibrating reed (7), and makes pole shoe (6) be positioned at the top of magnet steel (4).Be shaped on line hole (9) on the housing (1).
The structure that the present invention adopts interchange magnetic circuit and dc circuit magnetic loop to go the same way, select for use aluminium nickel cobalt 5 to make magnet steel as permanent magnet with certain permeability, pole shoe and following pole shoe are as magnetic conductor in the higher iron-nickel alloy 1j50 making of permeability, ensureing higher gap flux density value, and make it be operated in best operating point by magnetic circuit size reasonable in design.
Pole shoe plays movable magnetic pole in the present invention in magnetic circuit, works to increase the weight of quality again in vibrational system.The special shape of vibrating reed and the suitable weight of last pole shoe, make vibrational system be in the quality control state below the resonance frequency at it, and be different from common receiver vibrating diaphragm, make vibrational system not have the function of acoustic radiation substantially, but the vibrational energy major part is passed in the receiver housing, cause the body vibration of housing.
Operation principle: when leading to an alternating current in the coil, just there is an alternating magnetic field to add thereon on the permanent magnetic field in the magnetic circuit, magnetic field intensity in the magnetic circuit is changed up and down on the basis of field intensity when static former, the variation of magnetic field intensity, magnetic circuit is changed along with the variation of alternating current direction the suction of vibrating reed, like this, vibrating reed has produced the vibration identical with the alternating current frequency because of being subjected to suction.The signal of telecommunication so has been converted into force signal.The vibration of vibrating reed can cause the body vibration of product shell, and product closely contacts with the human skull during use, and our brain is just directly imported in the vibration of acoustical signal into through skull, realized the reception to acoustical signal.People's ear-drum is directly exposed in the environment sound field like this, the information of accepting air vibration at any time and being transmitted, and the communication information has solved the problem that communication and environmental information are neglected neither then by the skull transmission.
