Technical problem to be solved in the utility model is to provide a kind of loud speaker module, and this loud speaker module group assembling is easy, and the die sinking difficulty is low, and intracavity space is large, helps the lifting of loud speaker module acoustical behavior.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of loud speaker module, comprise the first housing and the second housing that are combined as a whole, contain loudspeaker monomer in the cavity that described the first housing and the second housing surround, described the first housing is provided be used to the shell fragment that connects described loudspeaker monomer and module external circuit, is provided with the shell fragment draw-in groove for fixing described shell fragment in described the first housing; Described shell fragment comprises the Access Division of inserting in described shell fragment draw-in groove, and described shell fragment also comprises that an end is connected with described Access Division, the bending part that the other end exposes described the second housing and with described module external circuit, is electrically connected to; Described Access Division is plate-like structure.
Wherein, connect as one by connecting portion between described Access Division and described bending part.
Wherein, described connecting portion and described Access Division are perpendicular.
Wherein, described the second housing is provided with for the retaining wall against described connecting portion.
Wherein, described retaining wall is step structure, and a cascaded surface and the described connecting portion of described step structure lean, and another cascaded surface of described step structure and the shape of described bending part are suitable.
Wherein, described the second housing is provided with the bar shaped perforate that passes for described bending part, a side of described perforate be on described retaining wall with the suitable cascaded surface of described bending part shape.
Wherein, described shell fragment draw-in groove is provided with two, two staggered be arrangeding in parallel of described shell fragment draw-in groove.
Wherein, described shell fragment is the drawing shell fragment.
After having adopted technique scheme, the beneficial effects of the utility model are:
, because the first housing of the utility model loud speaker module is provided with for the shell fragment that connects loudspeaker monomer and module external circuit, be provided with the shell fragment draw-in groove for fixation spring tab in the first housing; Shell fragment comprises the Access Division of inserting in the shell fragment draw-in groove, and shell fragment also comprises that an end is connected with Access Division, the bending part that the other end exposes the second housing and with the module external circuit, is electrically connected to; Access Division is plate-like structure.Shell fragment is combined with the first housing at shell plating shell with after drying technique, therefore not there will be the situation that the coating of shell fragment is destroyed or shell fragment is out of shape; And in conjunction with the time only the flat Access Division of shell fragment need to be inserted into the combination that can realize shell fragment and the first housing in shell fragment draw-in groove on the first housing, the plug-type combination of this kind is compared with injection moulding combination of the prior art, has the following advantages:
One, directly will get final product in the shell fragment draw-in groove on shell fragment insertion the first housing, fitting operation is easy;
Two, the plug-in type shell fragment does not need the first housing to have larger thickness, takes up room less, does not increase the die sinking difficulty, easily realizes;
Three,, for the product of limited space, can farthest for acoustic element, vacate the space of expansion, help the lifting of loud speaker module acoustical behavior.
Because the second housing is provided with for the retaining wall against the shell fragment connecting portion, retaining wall can firmly be fixed on shell fragment in the shell fragment draw-in groove, prevent that shell fragment from becoming flexible because of vibration or external impacts, thereby prevented because of loosening loudspeaker monomer and the loose contact of module external circuit that causes of shell fragment or opened circuit, having improved stability and the reliability of loud speaker module.
Be arranged in parallel because two shell fragment draw-in grooves are staggered, effectively utilized the structure of the first housing, take up room less, vacateed the space of expansion for acoustic element, help the raising of loud speaker module acoustical behavior.
In sum, the utility model loud speaker module has solved in prior art that loud speaker module processing and manufacturing difficulty is large, the technical problem such as the acoustical behavior room for promotion is little.The utility model loud speaker module group assembling is easy, and the die sinking difficulty is low, and intracavity space is large, helps the lifting of acoustical behavior; And stability and reliability are high.
