Abstract
Disclosed in the utility model is a loudspeaker module that comprises a first housing, a second housing, a single loudspeaker body contained between the first housing and the second housing, and an electric connection device electrically connected with the single loudspeaker body and an external electronic circuit. Specifically, the electric connection device is a circuit board that is fixed between the first housing and the second housing by direct stitching. The disclosed loudspeaker module has advantages of high reliability and high utilization rate of the module space.
Description
Technical field
The utility model relates to a kind of loud speaker module, and it is high especially to relate to a kind of reliability, the loud speaker module that the module space availability ratio is high.
Background technology
Along with the development of electroacoustic techniques, loudspeaker techniques is constantly ripe, and the application of loud speaker is also more and more wider, and the client is also more and more higher for the requirement of loud speaker.Extensive application in the portable type electronic product makes people also more and more higher to the reliability requirement of loud speaker module.
The loud speaker module of conventional art, loudspeaker monomer and external electronic circuits are electrically connected by arrangements of electric connection.Described arrangements of electric connection and the welding of loudspeaker monomer pad, after extend the loud speaker module and be electrically connected with external electronic circuits, its stationarity is poor, in the experiment of loud speaker module reliability and actual use procedure, arrangements of electric connection easily not firmly produces displacement with the loud speaker module because of fixing, thereby cause the pad open circuit, the loud speaker module performance is impacted, the loud speaker module reliability is reduced.
Therefore, be necessary the loud speaker module that provides a kind of reliability high.
The utility model content
Technical problem to be solved in the utility model provides the high loud speaker module of a kind of reliability, and can improve the space availability ratio of loud speaker module.
To achieve these goals, the utility model has adopted following technical scheme: a kind of loud speaker module, comprise the first housing, the second housing, be contained in the loudspeaker monomer between described the first housing and the second housing, and the arrangements of electric connection that is electrically connected described loudspeaker monomer and external electronic circuits, wherein, described arrangements of electric connection is circuit board, and described circuit board is fixed between described the first housing and the second housing by direct pressing.
As a kind of preferred technical scheme, described circuit board and described housing pressing partly are provided with location hole, and described the second housing correspondence position is provided with positioning convex.
As a kind of preferred technical scheme, the position that the corresponding described circuit board of described the second housing extends described loud speaker module is provided with locating notch, and the corresponding described locating notch of described the first housing position is provided with locating piece.
As a kind of preferred technical scheme, the circuit board of telling is electrically connected by inserting mode with described external electronic circuits.
Because circuit board directly is pressed together between the two housings, and two housings has Position Design, and the stationarity of circuit board and loud speaker module is good, but the reliability and stability of Effective Raise loud speaker module; Simultaneously, because press fit of circuit boards is between two housings, circuit board does not take loud speaker module internal space, has improved the space availability ratio of loud speaker module.Therefore, the utility model loud speaker module has the reliability height, the advantage that space availability ratio is good.
Description of drawings
Fig. 1 is the utility model embodiment stereogram.
Fig. 2 is the utility model embodiment exploded view.
Embodiment
Below in conjunction with accompanying drawing, describe the utility model loud speaker module in detail.Should know, below only be an embodiment of the utility model loud speaker module, is used for specifically describing the utility model, is not limited to the utility model.
See also Fig. 1, loud speaker module of the present utility model comprises the first housing 1, the second housing 2, is contained in the loudspeaker monomer between the first housing 1 and the second housing 2, and the arrangements of electric connection 3 that is electrically connected described loudspeaker monomer and external electronic circuits.The arrangements of electric connection of the utility model loud speaker module adopts circuit board.Circuit board 3 and described loudspeaker monomer pad welding are electrically connected with external electronic circuits after extending the loud speaker module.
See also Fig. 2, the fixed part 32 of circuit board 3 is between the contact-making surface that the first housing 1 and the second housing 2 connect, when the first housing 1 and 2 assembling of the second housing, circuit board 3 is fixed between the first housing 1 and the second housing 2 by fixed part 32 pressings, can effectively guarantees the fixation degree of circuit board 3.Simultaneously, be provided with location hole 31 on the fixed part 32 of circuit board 3, corresponding with location hole 31, be provided with positioning convex 21 on the second housing 2 with on fixed part 32 contact-making surfaces, during assembling, positioning convex 21 inserts in the location hole 31, has further fixed circuit board 3, has made things convenient for simultaneously the assembling of loud speaker module.
As shown in Figure 2, the position that the second housing 2 corresponding circuits plates 3 extend the loud speaker module offers locating notch 22, and is corresponding with locating notch 22, is provided with locating piece 12 on the first housing 1, and during installation, locating piece 12 is plugged in locating notch 22 inside.When circuit board 3 extends the loud speaker module, be fixed in the second housing by locating notch 22, avoided the lateral displacement of circuit board 3 extensions with respect to the loud speaker module, simultaneously, the locating piece 12 of the first housing 1 is plugged in the locating notch 22, has avoided the vertical displacement of circuit board 3 extensions with respect to the loud speaker module.
As shown in Figure 2, be provided with golden finger 4 on the circuit board 3, circuit board 3 is electrically connected by the mode of pegging graft with external electronic circuits by golden finger 4, has simplified the assembling of utility model loud speaker module and external electronic circuits.
Should be noted in the discussion above that a kind of as circuit board of flexible printed circuit (FPCB), can be applied to equally the utility model loud speaker module, do not affect enforcement of the present utility model and application.
It below only is an implementation case of the present utility model; be not limited to the utility model; as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection range of putting down in writing in claims.
