Abstract
The utility model provides a miniature loudspeaker, its including the casing that has an accommodating space with accept in speaker monomer in the accommodating space, the casing is equipped with out the sound hole and derives the sound that the speaker monomer sent, miniature loudspeaker still locates including the ring go out the sealing member of sound hole, the sealing member with the casing adopts double -shot moulding technology to mould plastics into a body structure. The utility model discloses miniature loudspeaker's play sound hole sealed effectual, speaker tone quality is effectual.
Description
[technical field]
The utility model belongs to electro-acoustic product technical field, particularly relates to a kind of Microspeaker.
[background technology]
In recent years along with the fast development of mobile communication technology, consumer uses the mobile communication equipment with phonetic function more and more, such as portable phone, handheld device, laptop computer, palmtop computer, multimedia player and can carry out by public or dedicated communications network other equipment of communicating.As the playing device of voice, Microspeaker design quality directly affects the speech performance of relative technological products.
Microspeaker is a kind of energy converter, and can convert electrical energy into radiating acoustic energy and go out, be parts indispensable in electro-acoustic product, Microspeaker mainly comprises housing, and in the cavity that described housing surrounds, collecting is fixed with loudspeaker monomer.
At present, the form that the Microspeaker of electro-acoustic product relevant to this case adopts side to speak, described housing side sets out sound hole, the sealing means of described sender for being sticked foam around it, but described loud speaker is in complete machine assembling process, easily producing scraping between described housing and described foam causes it to be shifted, hide described sender, described sender area is diminished, thus cause electro-acoustic product easily to produce total harmonic distortion (Totalharmonicdistortion, THD) and high order harmonic component distortion.
[utility model content]
For when solving the assembling of above-mentioned loud speaker because the scraping of its sender seal causes the technical problem being shifted and causing sender area to reduce, the utility model provides a kind of seal to fix, not easily scraping be shifted and the good Microspeaker of audio.
The utility model provides a kind of Microspeaker, it comprises the housing with receiving space and the loudspeaker monomer be contained in described receiving space, described housing is provided with the sound derivation that loudspeaker monomer sends by sender, described Microspeaker also comprises the seal being located on described sender, and described seal and described housing adopt two-shot molding process to be injection molded into integrative-structure.
In one preferred embodiment of the Microspeaker provided at the utility model, described housing comprises lug boss, and described seal comprises concave part, and concave part described in described raised portion fits fixes described seal in the periphery of described sender.
In one preferred embodiment of the Microspeaker provided at the utility model, described sender is located at the side of described housing.
In one preferred embodiment of the Microspeaker provided at the utility model, described seal is the sealing ring of quality of rubber materials.
Compared to prior art, in the described Microspeaker that the utility model provides, described sealing ring is set and is located at described sender, by the method for double-shot moulding, described seal and described housing are made of one structure, reduce the risk of complete machine assembling, avoid described seal when assembling described Microspeaker and the described sender size of displacement impact occurs, thus improve audio frequency output quality.
[accompanying drawing explanation]
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the schematic perspective view of the Microspeaker that the utility model provides;
Fig. 2 is the decomposed schematic diagram of the Microspeaker shown in Fig. 1.
[embodiment]
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, Fig. 1 is the schematic perspective view of the Microspeaker that the utility model provides.Described Microspeaker 1 comprises the housing 11 with receiving space and is contained in loudspeaker monomer (not shown) in described receiving space.Described housing 11 is provided with the sound derivation that loudspeaker monomer sends by sender 13, and described Microspeaker 1 also comprises the seal 15 being located on described sender 13 periphery.
Please refer to the decomposed schematic diagram that Fig. 2, Fig. 2 are Microspeakers shown in Fig. 1.Described sender 13 is located at the side of described housing 11, and described housing 11 is being provided with lug boss 131 around the position of described sender 13.
Described seal 15 is a rubber seal, described seal 15 is located on described sender 13, and flush with described housing 11 edge, described rubber seal 15 also comprises concave part 151, described concave part 151 coordinates fixing described seal 15 in described housing 11 with described lug boss 131, meanwhile, through two-shot molding process, described seal 15 is into a single integrated structure with described housing 11.
Arrange described seal 15 in the described Microspeaker 1 that the utility model provides and be located on described sender 13, described concave part 151 and described lug boss 131 coordinate fixing described seal 15 and described housing 11; Adopt two-shot molding process simultaneously, described seal 15 and described housing 11 are made of one structure, reduce the risk of complete machine assembling, avoid described seal 15 when assembling described Microspeaker 1 and described sender 13 size of displacement impact occurs, thus improve audio frequency output quality.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
