Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in figure 1, the invention provides a kind of loudspeaker module 100, including the housing 1 with receiving space and collecting Loudspeaker monomer 2 in housing 1.
Housing 1 includes the bottom wall for surrounding receiving space and the side wall from the bending extension of the edge of bottom wall 12, and side wall includes and bottom The relative upper surface of wall 12.Bottom wall 12 includes inner surface and outer surface on the other side.Use is provided with the inner surface of bottom wall 12 In the monomer fixed part 11 of fixed loudspeaker monomer 2.Specifically in the present embodiment, monomer fixed part 11 is located in bottom wall Centre so that the sidewall spacers of loudspeaker monomer 2 and housing 1 after installation are set.Wherein monomer fixed part 11 is around being located at loudspeaker The periphery of monomer 2, it is end to end circular step.The overlapping edges of loudspeaker monomer 2 are on the step.
Receiving space is divided into the preceding operatic tunes and the rear operatic tunes by loudspeaker monomer 2.Specifically in the present embodiment, loudspeaker list Body 2 is magnetic speaker, specifically includes vibrating diaphragm and the voice coil loudspeaker voice coil of driving vibration, and vibrating diaphragm includes ring and the ball on ring that is sticked Top.The vibrating diaphragm side of loudspeaker monomer 2 loads in monomer fixed part 11.Between the vibrating diaphragm and bottom wall 12 of loudspeaker monomer 2 before shape The preceding operatic tunes of loudspeaker module is formed between the vibrating diaphragm and bottom wall 12 of the operatic tunes, specially loudspeaker monomer;Loudspeaker monomer 2 and shell The rear operatic tunes of loudspeaker module is formed between body 1, plays a part of expanding the rear operatic tunes of loudspeaker monomer, low frequency sound can be improved It and should can significantly reduce F0.Certainly, loudspeaker monomer 2 can also be other kinds of microphone device, and its principle is identical.
Matching with loudspeaker monomer 2, monomer fixed part 11 is long strip type structure, including two first along long axis direction Two second edges 1102 along short-axis direction of two first edges 1101 of edge 1101 and connection.Specifically in the present embodiment, Monomer fixed part 11 forms a rectangular configuration.
Loudspeaker module includes the passage 13 of speaking extended to from monomer fixed part 11 outside side wall, and passage 13 of speaking is arranged on The side of vibrating diaphragm is simultaneously vertically arranged with the direction of vibration of vibrating diaphragm, and the preceding operatic tunes is connected by passage 13 of speaking with the external world.Monomer is fixed The through hole 130 for connecting speak passage 13 and the preceding operatic tunes is correspondingly offered in portion 11.,
As shown in Fig. 2 the inner surface of bottom wall 12 include close to speak the side of passage 13 the first inner surface 121, away from go out The second inner surface 122 and the extended surface 123 of the first inner surface 121 of connection and the second inner surface 122 of the side of sound passage 13.The One inner surface 121 is corresponding with passage 13 of speaking in the width spoken on direction of loudspeaker module;Second inner surface 122 is being raised one's voice The width spoken on direction of device module exceeds the first inner surface 121.
First inner surface 121 is connected with the second inner surface 122, the both ends of extended surface 123 respectively with the first inner surface 121 and Second inner surface 122 seamlessly transits.Second inner surface 122 is connected with first edge 1101, extended surface and the phase of second edge 1102 Even.
As in Figure 2-4, if using the plane where the top dome of vibrating diaphragm as horizontal plane, where the first inner surface 121 Angle between plane and horizontal plane is sharp angle α, and the angle between plane and horizontal plane where the second inner surface 122 is acute angle β, and sharp angle α < acute angles betas.Namely cause, in the preceding operatic tunes, the bottom wall of face vibrating diaphragm is spoken apart from the distance of vibrating diaphragm from close The side that the one of passage 13 is laterally away from passage 13 of speaking reduces.The outer surface of bottom wall is preferably a plane parallel to top dome. I.e. as shown in Fig. 2 d1 > d2., can be along due to the Action of Gravity Field of water so that after the preceding operatic tunes inner inlet of loudspeaker module Second inner surface 122 flows to the first inner surface 121 of lower, so as to which water be discharged from acoustic aperture 130 is gone out.
Second inner surface 122 is from the side of laterally closer first inner surface 121 away from the first inner surface 121 with raising one's voice The distance between device monomer 2 gradually increases, i.e., the drainage direction of d2 as shown in Figure 2 along the second inner surface 122 gradually increases.Its In the second inner surface 122 can be inclined-plane, or curved surface, be to implement as long as drainage can be played.It is excellent Choosing, the second inner surface 122 forms at least one inclined-plane.
Preferably, also there is certain angle between the second inner surface 122 and extended surface 123, so, can further function as The convergence effect of ponding so that ponding drains into the more easily along the boundary line between the second inner surface 122 and extended surface 123 One inner surface 121, improve the drainage performance of product.
Loudspeaker module 100 can also include the cover plate that a lid is connected on housing 1, and cover plate lid is connected on the upper surface of side wall 11 And set with case bonding, so that the rear operatic tunes of loudspeaker module forms the operatic tunes of closing.In other selectable implementations In mode, loudspeaker module can also be directly installed on the mounting surface in the external world, such as the plane such as the mainboard of electronic product, housing On, and can implement.
The bottom wall of loudspeaker module face vibrating diaphragm of the present invention apart from vibrating diaphragm distance from close to the one lateral remote of passage of speaking Side from the passage of speaking reduces.Allow and the passage and eventually through going out acoustic aperture of speaking is flowed into the water in the preceding operatic tunes Discharge, it can so avoid producing ponding in corner, so as to influence the performance of product.
Although embodiments of the invention have been shown and described above, it is to be understood that above-described embodiment is, example Property, it is impossible to limitation of the present invention is interpreted as, one of ordinary skill in the art within the scope of the invention can be to above-mentioned Embodiment is changed, changed, replacing and modification.
