Description

Bone conduction earphone

Technical field

The utility model relates to a kind of bone conduction earphone, and particularly a kind of noise is little, and bass is abundant, and the bone conduction earphone that gives great volume.

Background technology

Traditional PlayGear Stealth generally all is that earphone is attached to ear hole or plug in the ear hole, and earphone is by vibrate air, and air vibrates people's ear-drum again, and sound is passed to human brain.This PlayGear Stealth, owing to need in use earphone to be attached to the ear hole or to fill in the ear hole, like this, during sound in people are listening earphone, outside sound user is difficult to hear, like this, when facing a danger situation, as go across the road, just can't hear the sound of blowing a whistle of automobile, that is quite dangerous; In addition,, can cause people's tinnitus, seriously can cause hearing to descend if this earphone of long-term big volume ground use is influential to people's ear-drum.In order to address the above problem, people's utility model a kind of bone conduction earphone, this earphone is that the signal of telecommunication is become vibration signal, by contacting with the ear bones of human body, make the people hear sound, sound does not need through air borne, therefore, earphone also needn't be attached to the ear hole or fill in the ear hole, like this, when people when using the bone conduction earphone listening, can't influence the auditory function of people's ear, simultaneously, can people's ear-drum not had any impact yet.As the disclosed a kind of bone conduction earphone of Korean Patent document KR10-2010-0097869, a kind of product comes to this, it comprises loam cake (promptly being attached to the lid on the ear bones) and lower cover, in the cavity of described loam cake and lower cover formation, be provided with the bone-conduction speaker assembly, described loam cake is made up of two parts, loam cake main body and metal clips, described metal clips be fixed together by screw, described bone-conduction speaker assembly comprises magnet, coil, the three-jaw elastic component, described magnet is fixedlyed connected with described lower cover, described coil is enclosed within on the described magnet, is provided with the three-jaw elastic component above the skeleton of described coil, and the top of described three-jaw elastic component withstands on the metal clips of described loam cake.When coil electricity, along with the power variation of the signal of telecommunication, described coil is under the effect in magnetic field, coil vibrates, thereby drive described three-jaw elastic component vibration, the top of described three-jaw elastic component makes the metal clips vibration again, thereby can make people's ear bones hear sound.This bone conduction earphone, though be some problems that solved PlayGear Stealth, but, because the restriction of this body structure of this bone conduction earphone, when the volume of this earphone is big slightly, will be between the top and metal clips of three-jaw elastic component, or between metal clips and loam cake main body, produce noise, and influence the purity of sound; In addition, the bass of this bone conduction earphone is bad, makes the people sound uncomfortable, especially when listening to the music, feels that distortion is very serious.

The utility model content

The purpose of this utility model is to overcome above shortcoming, and providing a kind of to society does not almost have noise, and bass is abundant, bone conduction earphone simple in structure.

The technical solution of the utility model is: a kind of bone conduction earphone is provided, comprise loam cake and lower cover (promptly being attached to the lid part on the ear bones), after described loam cake and lower cover fasten, be formed for the cavity of hold bone conduction loudspeaker assembly, in described cavity, be provided with the bone-conduction speaker assembly, described lower cover is a single injection-molded, described lower cover has a plane of oscillation, described bone-conduction speaker assembly comprises magnet, coil and buffering ring, described magnet is fastened on the inwall of the plane of oscillation of described lower cover, on described magnet, be with buffering ring, on described buffering ring, be provided with described coil.

As to improvement of the present utility model, between the inwall of the plane of oscillation of described lower cover and described magnet, also be provided with metal clips, described metal clips is fixed on the inwall of the described plane of oscillation, and described magnet is fastened on the described metal clips.

As to further improvement of the utility model, described buffering ring is made of sponge; Perhaps make of silica gel; Perhaps use the EVA material; Perhaps make of rubber.

As to further improvement of the utility model, described magnet can be square column type or cylindrical;

Preferably, the longitudinal section of described magnet also can be T shape, and the plane of T shape magnet replaces metal clips directly to be fixed on the inwall of the described plane of oscillation.

Preferably, the longitudinal section of described magnet can also be E shape, and the plane of E shape magnet replaces metal clips directly to be fixed on the inwall of the described plane of oscillation.

In the above-mentioned various scheme, on described magnet, all can also be provided with iron core, to add the magnetic field conduction of strong magnet.Described iron core also can be cylindrical, square column type, T type or E type structure.

The lid part of fitting with otica that the utility model will have bone conduction earphone now, change once injection moulding into by traditional two parts (metal clips and cap body), and the structure that the transmission of sound is withstood on metal clips by traditional coil by the three-jaw elastic component, change into magnet or magnet are added the structure that metal clips is directly fixedlyed connected with the inwall of the plane of oscillation of lower cover, like this, just eliminate generation noise root, fundamentally solved souffle problem; Secondly, directly with the plane of oscillation of lower cover or fixedly connected above the metal clips, another side is gone to the bottom with coil and is fixedlyed connected with the buffering ring one side, like this, when coil vibrated, buffering ring can directly play the effect of buffering to the vibration of coil, so, can enrich the bass component of earphone.The utility model lacks than the number of spare parts of traditional bone conduction earphone, just have simple in structure, advantage with low cost.In sum, the utlity model has does not almost have noise, and bass is abundant, advantage simple in structure, with low cost.
