Abstract
The utility model discloses a vibration type loudspeaker. The loudspeaker is characterized in that the vibration type loudspeaker comprises a housing and an internal mechanical vibration unit, wherein the mechanical vibration unit comprises an elastic vibration sheet and a coil unit. The elastic vibration sheet is fixed on a vibration sheet support, wherein the vibration sheet support is fixed on the housing; the coil unit comprises coils, a rack, a magnetic core and a magnetic-core fixing iron block, wherein the coils are attached to the rack, the magnetic core is fixed between the magnetic-core fixing iron block and the rack, and the magnetic-core fixing iron block is fixed on the rack. The vibration type loudspeaker has the advantages including novel design and compact structure, wherein it is not require air, an ear cavity or an eardrum to spread sound, instead, vibrations directly stimulate auditory nerves to produce auditory senses; thus, the vibration type loudspeaker can be applied to noisy environments, and also to disabled people whose audibility is disabled but auditory nerves are sound.
Description
Technical field
The utility model relates to a kind of oscillating mode loud speaker, particularly a kind of loud speaker that can the mechanical oscillation of shell be obtained voice signal through the bone transmission.
Background technology
Traditional loud speaker is through air borne sound, obtains voice signal through vibrophone in the ear again, and in the very big occasion of ambient noise, the sound of loud speaker and outside sound get into ear simultaneously, cause ear to differentiate, and communication efficiency is low.
The utility model content
The technical problem that (one) will solve
The technical problem that the utility model will solve provides a kind of oscillating mode loud speaker that need not obtain voice signal through eardrum, thereby when receiving sound, does not receive the interference of extraneous noisy environment.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of oscillating mode loud speaker, and it comprises shell and inner mechanical vibration element, and said mechanical vibration element comprises:
Be fixed on the elastic vibration sheet on the vibrating reed support, said vibrating reed support is fixed on the shell;
Coil unit, said coil unit comprise fixedly iron block of coil, support, magnetic core and magnetic core, and said coil is attached on the said support, and said magnetic core is fixed in magnetic core fixedly between iron block and the support, and said magnetic core fixedly iron block is fixed on the support.
Fixedly be provided with pad between the iron block at said elastic vibration sheet and magnetic core.
Said elastic vibration sheet is provided with the synergy hole.
Said coil unit contains two coils, is located at said magnetic core both sides respectively.
(3) beneficial effect
The oscillating mode loud speaker of the utility model can convert the audio signal in the external world into the mechanical oscillation of vibrating reed through coil and magnetic core; The plastic casing that vibrating reed drives sealing vibrates; And then skull with housing contacts is vibrated stimulate auditory nerve, accomplish the conversion of electricity-sound.The oscillating mode loud speaker of use the utility model is applicable in the very big occasion of ambient noise and communicates, and is applicable to the hearing defectiveness but the intact individuals with disabilities of auditory nerve.
Description of drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the vertical view of the vibrating reed of the utility model.
Embodiment
Below in conjunction with accompanying drawing and execution mode the utility model is described further.
As shown in Figure 1, the oscillating mode loud speaker of the utility model is made up of with the mechanical vibration element that is fixed on enclosure the plastic casing 1 of sealing, and 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 through screw 9-1, and coil unit comprises fixedly iron block 7 of two coils 4, support 5, magnetic core 6 and magnetic core, and 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, is fixed in magnetic core fixedly between iron block 7 and the support 5, and magnetic core fixedly iron block 7 is fixed on the support through 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 through 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, vibrating effect that can enhance elasticity vibrating reed 2.
The oscillating mode loud speaker of the utility model is when work; Extraneous audio signal converts the mechanical oscillation of vibrating reed 2 into through 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, accomplish the conversion of electricity-sound.
The oscillating mode loud speaker of the utility model is novel, and compact conformation need not transmit sound through air approach and eardrum, but directly stimulate auditory nerve to produce the sense of hearing through osteoacusis vibration signal, can in noisy adverse circumstances, use.The oscillating mode loud speaker of the 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 oscillating mode 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.
Above-described only is the execution mode of the utility model; Should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; Can also make improvement, but these all belong to the protection range of the utility model.
