In order that technical problem, technical scheme and beneficial effect that the utility model is solved are more clearly understood, below With reference to drawings and Examples, the utility model is further elaborated.It should be appreciated that specific implementation described herein Example only to explain the utility model, is not used to limit the utility model.

As shown in Figure 1 and Figure 2, the In-Ear Headphones of low magnetism leakage half, including the earphone outer covering with host cavity, the host cavity There are framework 2, sounding component and magnetic circuit component 2, the surface of the magnetic circuit component is provided with reverse magnet 3.Produced by magnet Raw magnetic field, can partly be leaked to outside earphone outer covering, form magnetic dispersion, and reverse magnet can lead leakage to the part outside earphone outer covering It is back in internal magnetic circuit, this programme will be used to solving the reverse magnet of earphone magnetic leakage problem being placed on magnet assembly, for producing The raw reverse magnet for leading back to magnetic field can reduce magnetic dispersion, instead of the mode that tradition is placed on earphone cover, not only can be with Cover magnetic flux leakage is effectively reduced, and simplifies cover production process technology, it is to avoid cover occurs and scratches, glue phenomenon.

Further, the magnetic circuit component includes washer 4, be used to producing on the side of the washer magnetic field make it is described The magnet of sounding component vibrations, the reverse magnet 3 is on the opposite side opposite with the magnet side.Described washer 4 Effect with magnetic conduction, no washer means no uniform magnetic field, and earphone does not have higher sensitivity and relatively low distortion. Washer provides the uniform magnetic field required for voice coil loudspeaker voice coil motion.Its thickness and voice coil loudspeaker voice coil determines the bass distortion of loudspeaker around wide cooperation Size.

Further, the framework 2 is collar plate shape, and the center of the framework offers center recess 201, the magnetic Road component is on the center recess 201.Framework 2 is fixed in earphone outer covering, then based on framework, each sounding group Part, magnetic circuit component, washer etc. can be mounted respectively on framework, complete the installation of this product earphone, and its structure is more simple.

Yet further, installation omission 202 is offered on the outer circumference surface of the framework, facilitates framework to be fixedly installed to earphone In the host cavity of shell.

Also further, the washer 4 is circular magnetic conductive board, and the reverse magnet 3 is cylindrical type, the radius of the washer It is greater than the radius of the reverse magnet.The reverse magnet is a cylindrical type magnetic conduction sheet, and the magnetic conduction sheet is attached on the side of washer, So as to effectively reduce the cover magnetic flux leakage of earphone, and simplify the mounting means of the magnetic conduction sheet.

Specifically, the earphone outer covering includes earphone bonnet 102 and the cover 101 combined with the earphone bonnet, the magnetic Body is located at towards the side of cover, and reverse magnet is located at towards the side of earphone bonnet.The magnet is used to produce magnetic field, the magnetic field Drive shakes to touch sends sound with voice coil loudspeaker voice coil vibrations.And just effectively reduce the cover of earphone in oppositely arranged reverse magnet of magnet Magnetic flux leakage.

More specifically, be additionally provided with out acoustic aperture on the earphone outer covering, it is described go out acoustic aperture connected with host cavity.This goes out acoustic aperture can Individually it is located on cover, or is together combined with earphone bonnet by cover；

Specifically, the outer surface side wall of the earphone bonnet 102 is provided with arc notch, the outer surface of the cover 101 Breach corresponding with the arc notch also is provided with the wall of side, is set after the earphone bonnet is combined with cover on its outer surface side wall Have and acoustic aperture 103 be combined into out by the arc notch and the breach, it is described go out acoustic aperture connected with host cavity.Go out acoustic aperture connection outer The sound sent after boundary's environment and the host cavity in earphone outer covering, its internal sounding component vibrations mainly goes out acoustic aperture by this and passed Go out.

Further, opposite side relative with magnetic circuit component on the framework is provided with pcb board.Pcb board is used to receive earphone The electric signal of transmission, and noise reduction elements can be increased on pcb board, lift the tonequality and performance of earphone.

Further, the sounding component also includes the vibrating diaphragm and voice coil loudspeaker voice coil with the common side of the magnet.The voice coil loudspeaker voice coil is Current coil, is the important component of sounding component vibration component, and the performance of voice coil loudspeaker voice coil can influence the sound pressure frequency characteristic of earphone, Sound pressure level, impedance curve, distortion, transient response, earphone parameter, tonequality etc., particularly relation earphone bear power and life-span.

Further, some sound regulating holes 104, institute are additionally provided with the outer surface side wall of the cover 101 and earphone bonnet 102 Sound regulating hole is stated to connect with host cavity.The vibrating diaphragm of earphone bass part is when front and rear vibration, except will earphone outer covering forward , also can be towards radiative acoustic wave in earphone outer covering outside external radiation sound wave, the acoustic wave segment energy of the interior radiation of earphone outer covering is just wasted, The electro-acoustic conversion efficiency of earphone is natively low to have pity on, generally only a few percent, so waste really unfortunate.Therefore think To several sound regulating holes are opened up on earphone, the low-frequency sound wave being radiated in case is discharged again so that the electroacoustic of earphone turns Change more efficient, and the tonequality of enhancing earphone.

Also further, it is described to go out to be provided with Air Filter between acoustic aperture and sound regulating hole and the host cavity.Air Filter plays one Surely isolation external environment condition and the effect of host cavity in earphone outer covering, effectively prevent the particles such as dust from entering the collecting of earphone outer covering Intracavitary, to protect the sounding component and magnetic circuit component that it is internal, can increase the service life of earphone.

Following table is respectively that earphone is arranged on cover without using reverse magnet, reverse magnet, reverse magnet is arranged on magnetic circuit The magnetic flux leakage that three kinds of situations are tested cover on component, unit is mT

The utility model concrete principle：

Earphone outer covering is made up of earphone bonnet and cover, and sounding component and auxiliary for producing sound are provided with inside it The magnetic circuit component of sounding, mainly produces magnetic field by the magnetic circuit component, sounding component is produced the principle sounding of vibrations.And in magnetic The reverse magnet with magnet direction is placed on the framework of body component, the magnetic circuit magnetic field leaked at cover is led back into magnetic circuit, so that The purpose of reduction cover magnetic leakage is reached, as seen from the above table, reverse magnet, which is placed on magnetic circuit component, not only can effectively drop Bottom surface lid magnetic flux leakage, and simplify cover production process technology, it is to avoid there is cover and scratch, glue phenomenon.

It is to combine one or more embodiments that particular content is provided as described above, does not assert tool of the present utility model Body is implemented to be confined to these explanations.It is all approximate with method of the present utility model, structure etc., identical or new for this practicality Some technologies are made under type concept thereof to deduce, or replacement should all be considered as protection domain of the present utility model.
