Description
Technical field
The utility model relates to the electro-acoustic product technical field, particularly a kind of loud speaker module.
Background technology
Along with the develop rapidly of electronic industry, portable type electronic product has more and more tended to ultra-thinization structural development, also just need be to ultra-thinization architecture advances as the loud speaker module of important acoustical device in the electronic product.Existing loud speaker module comprises loudspeaker monomer and is used for accommodating the fixedly housing of loudspeaker monomer, loudspeaker monomer involving vibrations system and magnetic circuit system, vibrational system comprises vibrating diaphragm and voice coil loudspeaker voice coil, vibrating diaphragm comprises ball top and the ring portion of starting of oscillation action usefulness, be surrounded with edge part around the ring portion, edge part is fixed in the location that is used for vibrating diaphragm on the housing.Housing is that plastic material makes, in order to guarantee the mechanical strength of loud speaker module, have certain thickness with regard to the housing that needs the loud speaker module, this thickness is generally 0.5mm, so adopt the housing of plastic material to be difficult to satisfy the loud speaker module to the demand for development of superthin structure.
Slimming design for the ease of product, prior art usually on housing the position over against loudspeaker monomer be provided with metal insert, metal insert is the flake structure of metal, under less thickness, can reach the housing desirable strength, be provided with in the position over against loudspeaker monomer simultaneously and be beneficial to the size that increases loudspeaker monomer and the oscillation space of vibrating diaphragm, improve the module acoustical behavior.But, metal insert is less with the position plastic cement amount that the housing injection moulding is combined in the loud speaker module of existing structure, this is in order not increase the thickness of loud speaker module, so metal insert can produce resonance when vibrating diaphragm vibrates, even can rupture with the position that the housing injection moulding is combined at metal insert, shortened the useful life of loud speaker module.
The utility model content
Technical problem to be solved in the utility model provides a kind of loud speaker module, and the metal insert of this loud speaker module and the position mechanical strength height that the housing injection moulding is combined have effectively suppressed the resonance of metal insert and the generation of housing crack conditions.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of loud speaker module, comprise loudspeaker monomer and the housing that is used for accommodating described loudspeaker monomer, vibrating diaphragm position corresponding to described loudspeaker monomer on the described housing is provided with metal insert, be enclosed with the plastic stent for fixing described metal insert around the described metal insert, the position that is enclosed with described metal insert on the described plastic stent is provided with the reinforcing band that stretches out to the inner chamber of described loud speaker module, described reinforcing band corresponding with the edge part of described vibrating diaphragm and and described vibrating diaphragm between leave the vibration gap.
Wherein, described reinforcing band is the curved wall suitable with described ring portion with respect to the sidewall of the ring portion of described vibrating diaphragm.
Wherein, described reinforcing band is the raised strip with described plastic stent integrative-structure.
Wherein, described housing comprises first housing, and described first housing is by described metal insert and plastic stent injection moulding be combined into.
Owing to adopted technique scheme, the beneficial effects of the utility model are: the vibrating diaphragm position corresponding to loudspeaker monomer on the housing of the present utility model is provided with metal insert, be enclosed with the plastic stent for the fixing metal inserts around the metal insert, the position that is enclosed with metal insert on the plastic stent is provided with the reinforcing band that stretches out to the inner chamber of loud speaker module, reinforcing band corresponding with the edge part of vibrating diaphragm and and vibrating diaphragm between leave the vibration gap.The reinforcing band that stretches out to loud speaker module inner chamber on the plastic stent has increased the plastic stent thickness of metal insert and housing junction, increased the mechanical strength of metal insert and housing junction, can effectively suppress the phenomenon that metal insert and vibrating diaphragm resonate in the existing loud speaker module, the phenomenon that has also prevented simultaneously the fracture of metal insert and housing junction takes place, effectively raise the acoustical behavior of loud speaker module, prolonged the useful life of loud speaker module.Reinforcing band is corresponding with the edge part of vibrating diaphragm, and the Oscillation Amplitude of vibrating diaphragm is less herein, sets up other structure that reinforcing band can not influence the loud speaker module herein.
As seen, the utility model fully and has cleverly utilized the inner space of loud speaker module, the metal insert that has solved loud speaker module in the prior art under the condition of the volume that does not increase the loud speaker module easily and vibrating diaphragm resonates and the technical problem of metal insert and housing junction easy fracture, increase the overall performance of loud speaker module, prolonged the useful life of loud speaker module.
