Description
Technical field
The utility model relates to electroacoustic field, especially relates to a kind of Microspeaker.
Background technology
Microspeaker of the prior art generally includes vibrating diaphragm, and in the Microspeaker course of work, the up-down vibration of vibrating diaphragm produces sound.In order to ensure the acoustical behavior of Microspeaker, vibrating diaphragm is formed by multilayer material conventionally, but because thickness in each layer of vibrating diaphragm forming process exists certain error, causes vibrating diaphragm variable thickness to cause, and vibrating diaphragm consistency is poor, affects the acoustical behavior of product.Improve as one, can adopt the silicon rubber vibrating diaphragm of individual layer, but silicon rubber vibrating diaphragm is softer, need to adopt with silicon rubber and shake membrane-bound support portion by silicon rubber vibrating diaphragm and other structure secure bond of Microspeaker.The stability that the silicon rubber vibrating diaphragm of traditional structure is combined with support portion is not high, in the Microspeaker course of work, easily produces the phenomenon that silicon rubber vibrating diaphragm and support portion depart from, and Microspeaker reliability is caused to adverse effect.
Therefore, be necessary the Microspeaker structure of traditional structure to improve, to avoid above-mentioned defect.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Microspeaker, makes vibrating diaphragm and strutting piece strong bonded, improves stability and the reliability of Microspeaker.
To achieve these goals, the utility model is by the following technical solutions:
A kind of Microspeaker, comprise vibrating diaphragm assembly, described vibrating diaphragm assembly comprises vibrating diaphragm and is incorporated into the support portion at described vibrating diaphragm edge, described vibrating diaphragm is silicon rubber vibrating diaphragm, described vibrating diaphragm and described support portion are fixed, and: described support portion comprises the inwall fixing with described vibrating diaphragm, on the inwall of described support portion, is provided with depression away from described vibrating diaphragm direction, the corresponding described support portion of described vibrating diaphragm depression is provided with the contact site of protrusion, and inwall depression in described support portion is combined closely with described vibrating diaphragm contact site.
As the preferred technical scheme of one, described vibrating diaphragm assembly is rectangle, and described support portion and described vibrating diaphragm are rectangle, and inwall depression in described support portion is arranged at described rectangular four bights, and described vibrating diaphragm contact site correspondence is arranged at four bights.
As the preferred technical scheme of one, inwall depression in described support portion is arc, and the corresponding described depression of described vibrating diaphragm contact site is also arc.
As the preferred technical scheme of one, described support portion is metal material, and described vibrating diaphragm and described support portion are adhesively fixed.
As the preferred technical scheme of one, described support portion is plastic material, and described vibrating diaphragm and the injection moulding of described support portion are fixed.
The utility model Microspeaker, silicon rubber vibrating diaphragm and strutting piece inwall secure bond, on strutting piece inwall, be provided with depression away from vibrating diaphragm direction, the corresponding strutting piece inwall depression of silicon rubber vibrating diaphragm is provided with the contact site of protrusion, contact site and depression secure bond, can effectively increase the bonded area of silicon rubber vibrating diaphragm and support portion, improve the fastness that silicon rubber vibrating diaphragm is combined with support portion, thereby avoid in the Microspeaker course of work silicon rubber vibrating diaphragm and support section from, improve the reliability and stability of Microspeaker.

Embodiment
By reference to the accompanying drawings, describe the utility model Microspeaker structure in detail below.
As shown in drawings, the vibrating diaphragm assembly of the utility model Microspeaker, comprise silicon rubber vibrating diaphragm 2 and the support portion 1 with silicon rubber vibrating diaphragm 2 secure bond, as depicted in figs. 1 and 2, support portion 1 is arranged at silicon rubber vibrating diaphragm 2 outsides, silicon rubber vibrating diaphragm 2 is combined by other structures of support portion 1 and Microspeaker, plays a supporting role to silicon rubber vibrating diaphragm 2 in support portion 1.
As shown in accompanying drawing 2, accompanying drawing 3 and accompanying drawing 4, the fixing inwall of support portion 1 and silicon rubber vibrating diaphragm 2 is provided with the depression 12 that material forms, as shown in Figure 2 and Figure 4, depression 12 on 1 inwall of the corresponding support portion of rubber vibrating diaphragm 2 is provided with the contact site 22 of protrusion, contact site 22 is corresponding with depression 12 shapes, and contact site 22 is combined closely with depression 12.The vibrating diaphragm assembly of the utility model Microspeaker, silicon rubber vibrating diaphragm 2 and support portion 1 inwall secure bond, and the depression 12 of support portion 1 is combined closely with the contact site 22 of silicon rubber vibrating diaphragm 2, the structure of the utility model Microspeaker vibrating diaphragm assembly has effectively increased the bonded area of silicon rubber vibrating diaphragm 2 with support portion 1, improve the fastness of silicon rubber vibrating diaphragm 2 and support portion 1 combination, thereby avoid silicon rubber vibrating diaphragm 2 in the Microspeaker course of work to separate with support portion 1, improve the reliability and stability of Microspeaker.
As shown in drawings, as an embodiment of the present utility model, diagram vibrating diaphragm assembly is rectangle structure, support portion 1 and silicon rubber vibrating diaphragm 2 are rectangle structure, the depression 12 of support portion 1 is arranged at four bights of rectangle structure, corresponding with it, the contact site 22 of silicon rubber vibrating diaphragm 2 is corresponding four bights that are arranged at rectangle structure also, to improve the firm degree of combination of silicon rubber vibrating diaphragm 2 and support portion 1.
As shown in drawings, as the preferred technical scheme of one, the support portion 1 inwall depression 12 of the utility model Microspeaker is arcuate structure, corresponding with it, the contact site 22 of silicon rubber vibrating diaphragm 2 is also arcuate structure, the depression 12 of arcuate structure can be combined better with the contact site 22 of arcuate structure, improves the bonded area of silicon rubber vibrating diaphragm 2 and support portion 1, improves the firm degree of silicon rubber vibrating diaphragm 2 and support portion 1 combination.
In actual application, support portion 1 can be metal material, can be also plastic material, does not all affect the advantage applies of the utility model Microspeaker.In order to ensure the firm degree of combination of silicon rubber vibrating diaphragm 2 and support portion 1, in the time that support portion 1 is metal material, support portion 1 adopts bonding mode to fix with silicon rubber vibrating diaphragm 2; In the time that support portion 1 is plastic material, support portion 1 adopts the mode of injection moulding to fix with silicon rubber vibrating diaphragm 2.
These are only the utility model case study on implementation, be not limited to the utility model, as long as the equivalence that those of ordinary skill in the art do according to the utility model institute disclosure is modified or changed, all should include in the protection range of recording in claims.
