Abstract
The utility model relates to a vibratory loudspeaker, which is composed of a housing and an internal mechanical vibration unit, the mechanical vibration unit comprises an elastic vibration sheet welded on a vibration sheet bracket, the vibration sheet bracket is arranged fixedly on the housing by screws; a winding unit comprising a winding, a bracket, a magnetic core and a magnetic core fixing block, the winding is clung onto the bracket, the magnetic core is arranged between the magnetic core fixing block and the bracket, the magnetic core fixing block is arranged fixedly on the bracket by screws; a gasket is arranged between the elastic vibration sheet and the magnetic core fixing block. The vibratory loudspeaker has novel conception and compact structure, and can transfer sound in no need of air, ear cavity and eardrum, and can directly vibrate and stimulate auditory to generate hearing, and is practical in severe environment, the vibratory loudspeaker is suitable for handicapped persons with defective hearing and perfect auditory nerve.
Description
Technical field
The utility model relates to a kind of vibrating speaker, particularly a kind of loud speaker that the mechanical oscillation of shell can be obtained voice signal by the bone transmission.
Background technology
Traditional loud speaker is through air borne sound, obtains voice signal by vibrophone in the ear again, and in the very big occasion of ambient noise, the sound of loud speaker and outside sound enter ear simultaneously, cause ear to differentiate, and communication efficiency is low.
The utility model content
In order to overcome the problems referred to above, the utility model provides a kind of vibrating speaker that does not need to obtain by eardrum voice signal, thereby is not subjected to the interference of extraneous noisy environment when receiving sound.
Vibrating speaker of the present utility model is made up of shell and inner mechanical vibration element,
Wherein, mechanical vibration element comprises:
Be welded on the elastic vibration sheet on the vibrating reed support, the vibrating reed support by screw on shell;
Coil unit comprises fixedly iron block of coil, support, magnetic core and magnetic core, and coil is attached on the support, magnetic core be fixed in magnetic core fixedly between iron block and the support, magnetic core fixedly iron block by screw on support;
Fixedly be provided with pad between the iron block at elastic vibration sheet and magnetic core.
Preferably, said elastic vibration sheet is provided with the synergy hole; Said coil unit contains two coils, is located at the both sides of magnetic core respectively; Said pad is the stainless steel gasket of 0.1 millimeter thickness; Said pad is provided with two.
Vibrating speaker of the present utility model can be converted to the audio signal in the external world mechanical oscillation of vibrating reed by coil and magnetic core, the plastic casing that vibrating reed drives sealing vibrates, and then skull with housing contacts is vibrated stimulate auditory nerve, finish electricity-sound conversion.Use vibrating speaker of the present utility model to be applicable in the very big occasion of ambient noise and communicate, and be applicable to the hearing defectiveness but the intact individuals with disabilities of auditory nerve.
Description of drawings
Fig. 1 is the front view of vibrating speaker.
Fig. 2 is the vertical view of vibrating reed.
Wherein, 1 is shell, and 2 is vibrating reed, and 3 is the vibrating reed support, and 4 is coil, and 5 is support, and 6 is magnetic core, and 7 are the fixing iron block of magnetic core, and 8 is pad, and 9-1,9-2,9-3 are screw, and 10 are the synergy hole.
Embodiment
As shown in Figure 1, vibrating speaker of the present utility model is made up of with the mechanical vibration element that is fixed on enclosure the plastic casing 1 of sealing, mechanical vibration element comprises elastic vibration sheet 2, elastic vibration sheet 2 is welded on the vibrating reed support 3, vibrating reed support 3 is fixed on the shell 1 by screw 9-1, coil unit comprises two coils 4, support 5, magnetic core 6 and magnetic core be iron block 7 fixedly, coil 4 is attached on the support 5, be located at the two ends of support 5 respectively, magnetic core 6 is positioned at the central authorities of two coils 4, be fixed in magnetic core fixedly between iron block 7 and the support 5, magnetic core fixedly iron block 7 is fixed on the support by screw 9-3, fixedly be provided with the stainless steel gasket 8 of two 0.1mm thickness between the iron block 7 at elastic vibration sheet and magnetic core, 9-2 fixes by screw.As shown in Figure 2, vibrating reed 2 is weldingly connected with vibrating reed support 3, and elastic vibration sheet 2 evenly is placed with synergy hole 10, can strengthen the vibrating effect of elastic vibration sheet 2.
Vibrating speaker of the present utility model is when work, extraneous audio signal is converted to the mechanical oscillation of vibrating reed 2 by coil 4 and magnetic core 6, vibrating reed 2 drives the sealed plastic shell 1 that is attached thereto and vibrates, and then otica with housing contacts is vibrated stimulate auditory nerve, finish electricity-sound conversion.
Vibrating speaker of the present utility model is novel, and compact conformation does not need to transmit sound by air approach and eardrum, but directly stimulates auditory nerve to produce the sense of hearing by osteoacusis vibration signal, can use in noisy adverse circumstances.Vibrating speaker of the present utility model can be applicable to most occasions, and a very important person auditory nerve is intact, and the aurally handicapped also can hear sound, therefore can be used as hearing aids to a certain extent and use.This vibration loud speaker is specially adapted in wireless operator, battlefield soldier, broadcasting station TV announcer, the fire fighter who gos deep into the scene of a fire, the lowered in field environment staff of conversation and live report, also is applicable to the hearing defectiveness but the intact individuals with disabilities of auditory nerve.
