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 the ultrathin structural development, also just need to be to the ultrathin 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, housing is that plastic material makes, in order to guarantee the mechanical strength of loud speaker module, has certain thickness with regard to the housing that needs the loud speaker module, this thickness is generally 0.5mm, therefore adopt the housing of plastic material to be difficult to satisfy the loud speaker module to the demand for development of superthin structure.For above deficiency, increased metal insert at the loud speaker module, metal insert is a sheet metal, in order to satisfy it to the requirement of superthin structure development in the mechanical strength that guarantees the loud speaker module.At present, be to adopt the technique of injection moulding that metal insert and plastic casing are combined as a whole, adopt this kind technique just need to be provided with installation portion at the periphery of metal insert, be used for fixing metal inserts when injection moulding.The metal insert of this structure needs the installation portion on it is pruned after injection moulding finishes, and operation is loaded down with trivial details, and the processing and fabricating time of product is long, and production efficiency is low.
The utility model content
Technical problem to be solved in the utility model provides a kind of loud speaker module, and this loud speaker module production process is simple, and the processing and fabricating time of product is short, and production efficiency is high.
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 holding described loudspeaker monomer, described housing comprises the first housing and the second housing that is combined as a whole, the position of corresponding described loudspeaker monomer is provided with metal insert on described the first housing, the position that contacts with described loudspeaker monomer on the described metal insert is provided with location hole, and described loudspeaker monomer is provided with for the seal with described location hole sealing.
As a kind of improvement, described location hole is two, and described two location holes are with respect to the Central Symmetry setting of described metal insert.
As further improvement, described seal is the foam seal.
The beneficial effects of the utility model are: the position of the corresponding loudspeaker monomer of the first housing of loud speaker module described in the utility model is provided with metal insert, the position that metal insert contacts with loudspeaker monomer is provided with location hole, and loudspeaker monomer is provided with seal; Compare with the metal insert of the installation portion that is provided with assist location in the prior art, metal insert described in the utility model is that the body at metal insert is provided with location hole, when carrying out the injection moulding operation of the first housing, only the location hole on the metal insert and the alignment pin on the injection mold need to be fixed and carry out injection molding, after the injection moulding operation finishes, only need to take off the assembly working that can carry out next step from alignment pin in connection with the first housing that metal insert is arranged, and do not need to carry out the operation that the installation portion of metal insert is pruned of the prior art, in the assembling procedure that carries out the loud speaker module, seal on the loudspeaker monomer can seal location hole under the squeezing action of housing, can guarantee that outside foreign material can not enter the loud speaker module internal from location hole, therefore the utility model has reduced production process on the basis that has guaranteed the original service behaviour of loud speaker module, saved the production time of product, and then provide cost savings, improved output.
Because location hole is two, and two location holes are with respect to the Central Symmetry setting of metal insert; This metal insert that is arranged with two location holes is guaranteeing well in the location, and structure is the simplest, processes the easiest.
In sum, it is loaded down with trivial details that loud speaker module described in the utility model has solved in the prior art loud speaker module production process, produces technical problem long in time limit, has production process succinct, and the production and processing time is short, and cost is low, the output advantages of higher.

Embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.
Shown in Fig. 1, Fig. 2 Fig. 3 and Fig. 4 are common, a kind of loud speaker module, comprise loudspeaker monomer 2 and the housing that is used for holding loudspeaker monomer 2, housing comprises the first housing 11 and the second housing 12 that is combined as a whole, the position of corresponding loudspeaker monomer 2 is provided with metal insert 3 on the first housing 11, the position that contacts with loudspeaker monomer 2 on the metal insert 3 is provided with location hole 30, and loudspeaker monomer 2 is provided with for the seal 20 with location hole 30 sealings.Compare with the metal insert of the installation portion that is provided with assist location in the prior art, metal insert described in the utility model is that the body at metal insert 3 is provided with location hole 30, when carrying out the injection moulding operation of the first housing 11, only the location hole 30 on the metal insert 3 and alignment pin on the injection mold need to be fixed and carry out injection molding, after the injection moulding operation finishes, only need to take off the assembly working that can carry out next step from alignment pin in connection with the first housing 11 that metal insert 3 is arranged, and do not need to carry out the operation that the installation portion of metal insert is pruned of the prior art, in the assembling procedure that carries out the loud speaker module, seal 20 on the loudspeaker monomer can seal location hole 30 under the squeezing action of housing, can guarantee that outside foreign material can not enter the loud speaker module internal from location hole 30, therefore the utility model has reduced production process on the basis that has guaranteed the original service behaviour of loud speaker module, saved the production time of product, and then provide cost savings, improved output.
Location hole 30 is two, and two location holes are with respect to the Central Symmetry setting of described metal insert 3, and the metal insert 3 of this structure is guaranteeing well in the location, and structure is the simplest, processes the easiest.
The loud speaker module also comprises connector 4, and connector 4 is the FPCB(flexible printed circuit board), be used for being electrically connected between loudspeaker monomer 2 and the external electronic circuits.
Assembling process of the present utility model: at first metal insert 3 is fixed on the alignment pin of injection mold, carry out the injection molding of the first housing 11, take off in connection with the alignment pin of the first housing 11 that metal insert 3 is arranged from injection mold after injection molding is finished, can carry out the assembly working of next step loud speaker module; Then loudspeaker monomer 2 is installed in the inner chamber that is formed by the first housing 11 and the second housing 12, and the first housing 11 and the second housing 12 combined closely, foam on the loudspeaker monomer 2 can with location hole 30 sealings, namely have been finished the assembling procedure of above-mentioned loud speaker module under the squeezing action of housing at this moment.
