Description

A kind of loud speaker module
Technical field
The utility model relates to electroacoustic field, is specifically related to a kind of loud speaker module.
Background technology
Loud speaker module comprises loudspeaker monomer and accommodates the fixedly peripheral frame of loudspeaker monomer, and peripheral frame employing plastic material, because the intensity of plastic material is lower, needs the thickness of plastics peripheral frame larger in order to reach desirable strength conventionally conventionally.In prior art, peripheral frame is combined as a whole by a plurality of independently housings conventionally, and the thickness that wherein affects the housing of peripheral frame short transverse can directly have influence on the thickness of peripheral frame or loud speaker module.And at present due to over against loudspeaker monomer top shell or bottom shell all adopt thicker plastic material, therefore be unfavorable for reducing the thickness of loud speaker module, or the space of loud speaker module internal can be restricted in the situation that loud speaker module thickness is certain, accordingly just the size of loud speaker module internal part need to be reduced, thereby the acoustical behavior of loud speaker module can be reduced.
Therefore, be necessary the loud speaker module of this structure to improve, to avoid above-mentioned defect.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of loud speaker module, the inner space that can increase loud speaker module, the acoustical behavior of raising product.
To achieve these goals, the utility model provides a kind of loud speaker module, comprise loudspeaker monomer and accommodate the peripheral frame of fixing described loudspeaker monomer, described peripheral frame is integrated by mode secure bond such as bondings by some housings, wherein, the housing that is positioned at loud speaker module end face and/or bottom surface is metal material, and the described housing of metal material and other housings are by the mode secure bond of bonding.
In addition, preferred scheme is that described metal shell is laminated structure.
In addition, preferred scheme is, described peripheral frame comprises the first housing, the second housing and the 3rd housing, described the first housing and/or described the 3rd housing adopt metal material, it is plastic material that described the second housing is incorporated between described the first housing and described the second housing, and described the first housing and/or the 3rd housing and described the second housing are by the mode secure bond of bonding.
In addition, preferably scheme is, the edge of described the first housing and/or the 3rd housing and described the second housing gluing secure bond.
In addition, preferably scheme is, described loudspeaker monomer involving vibrations system and magnetic circuit system, and described the first housing is that metal material is arranged at described magnetic circuit system one side, is provided with the hole of dodging of material formation on described the first housing over against a side of described magnetic circuit system.
In addition, preferably scheme is, described loudspeaker monomer involving vibrations system and magnetic circuit system, and described the 3rd housing is metal material, described the 3rd housing is arranged at described vibrational system one side.
Adopt after technique scheme, compare with traditional structure, the top of the utility model loud speaker module peripheral frame and/or the housing of bottom adopt metal material, because the thickness of shell of metal material hour can reach larger intensity, thereby can increase the inner space of loud speaker module, improve the size of loudspeaker monomer and the volume of internal cavities, thereby be conducive to improve the acoustical behavior of product.
Accompanying drawing explanation
By below in conjunction with accompanying drawing, the utility model being described, above-mentioned feature of the present utility model and technological merit will become apparent and easily understand.
Fig. 1 is the stereo decomposing structural representation of the utility model loud speaker module;
Fig. 2 is the perspective view of the utility model loud speaker module.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to further detailed description.
As depicted in figs. 1 and 2, loud speaker module comprises loudspeaker monomer and accommodates the peripheral frame of fixing described loudspeaker monomer, wherein loudspeaker monomer involving vibrations system and magnetic circuit system, the present embodiment peripheral frame is by 13 3 of the first housing 11, the second housing 12 and the 3rd housings housing connecting shaping independently.The vibrational system of loudspeaker monomer comprises vibrating diaphragm 21 and the voice coil loudspeaker voice coil that is incorporated into vibrating diaphragm 21 1 sides, and magnetic circuit system comprises washer, magnet 22 and the magnetic conductive board 23 of combination successively, and magnetic circuit system forms the magnetic gap of accommodating voice coil loudspeaker voice coil.In the present embodiment, vibrating diaphragm 21, the second housing 12 middle parts of the second housing 12 and the 3rd housing 13 secure bond vibrational systems hollow out and can be used for accommodating whole vibrational system and magnetic circuit system, and the first housing 11 is arranged at a side at magnetic circuit system place.
In the present embodiment, the first housing 11 is metal material, the second housing 12 and the 3rd housing 13 adopt plastic material, on the first housing 11, over against the position of magnetic circuit system magnetic conductive board 23, be provided with accommodate fixing vibrational system dodge hole 110, dodging hole 110 can make magnetic circuit system be exposed to the outside of the first housing 11, thereby be conducive to increase the size of magnetic circuit system, be conducive to improve the acoustical behavior of product.Wherein, the first housing 11 and the second housing 12 are by the mode secure bond of gluing, on the second housing 12, corresponding to a side of the first housing 11, are provided with the faying face 120 with the first housing 11 secure bond.This metal shell and plastic casing directly can more be saved the space of product by the mode of gluing secure bond, thereby are conducive to improve the size of loudspeaker monomer or the volume of the rear operatic tunes of increase, thereby are conducive to improve the acoustical behavior of product.
In addition, the first housing 11 is laminated structure, and the edge of sheet the first housing 11 and the second housing 12 are integrated by the mode secure bond of bonding.With first the metalwork of laminated structure is injected in plastic casing, and then the housing of injection moulding metalwork is compared with the structure of other housing secure bond, whole housing over against loudspeaker monomer in this peripheral frame all adopts the structure of metal material more can save space, be conducive to improve the size of loudspeaker monomer or the volume of the rear operatic tunes of increase, thereby be conducive to improve the acoustical behavior of product.
