Description

The diaphragm of loudspeaker
Technical field
The utility model relates to electroacoustic field, is specifically related to a kind of diaphragm of loudspeaker.
Background technology
Loud speaker is a kind of electro-acoustic element converting electrical signals to acoustical signal, generally include magnetic circuit system, vibrational system and auxiliary system, and vibrational system comprises voice coil loudspeaker voice coil and vibrating diaphragm.Loud speaker operationally, voice coil loudspeaker voice coil is under the effect of electromagnetic field, do the motion of the reciprocating cutting magnetic line of force, produce displacement, thus drive coupled diaphragm oscillations, sound wave is delivered to the external world by cavity passage of speaking, instigate air sounding, can say, in the structure of loud speaker, vibrating diaphragm affects the vitals that loud speaker sound puts effect.
For existing rectangle vibrating diaphragm, the height of its entirety mainly comprises height and the corner height of long and short axle.Fig. 2 Fig. 3 is respectively the vertical view of traditional rectangle diaphragm structure and the cutaway view along A-A line, can find out, rectangle surround adopts contour design, namely major and minor axis ring height d1 is equal with corner ring height d1, this design comparison is simple, and for common loud speaker, this simple vibrating diaphragm design can meet its requirement to performance and reliability aspect.But this design can make the debud mode of properties of product be limited to, for the loud speaker that some Performance And Reliability demands are higher, then cannot debug product better.
Therefore, for above problem, be necessary to improve the design of surround, make it easy to the debugging of properties of product, to meet the higher performance of product and reliability requirement.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of diaphragm of loudspeaker, when not changing vibrating diaphragm part, by adjusting the height of surround, making it design variation, carrying out the debugging of properties of product better.
To achieve these goals, the utility model by the following technical solutions: a kind of diaphragm of loudspeaker, comprises ring portion, and wherein, described vibrating diaphragm is rectangle; Described ring portion comprises two the major axis portions and two minor axis portions that lay respectively at offside; The bight of vibrating diaphragm is provided with between adjacent described major axis portion and described minor axis portion; The height in described major axis portion and described minor axis portion is equal; The height in described bight and described major axis portion, described minor axis portion is not etc.
Wherein, the height in described bight is less than the height in described major axis portion, described minor axis portion.
Wherein, the height in described bight is greater than the height in described major axis portion, described minor axis portion.
Wherein, the height in four bights in described ring portion is equal.
Wherein, described vibrating diaphragm comprises upper and lower two-layer substrate layer; Described substrate layer is polyetheretherketonematerials materials layer; Glue-line is provided with between described substrate layer; Described polyetheretherketonematerials materials layer is fixing by described glue-line bonding.
Wherein, described vibrating diaphragm is the composite construction of polyetheretherketonematerials materials layer and Thermoplastic polyurethane elastomer material layer.
Compared to existing technologies, the diaphragm of loudspeaker of the present utility model, ring bight and long and short axle adopt not contour design, make the design of ring corner more flexible, diversified, thus be more conducive to debugging properties of product, to improve distortion, optimizing product performance and improve reliability be all very helpful.

Reference numeral wherein comprises: 1, ring portion, and 2, major axis portion, 3, minor axis portion, 4, bight.
Embodiment
Below in conjunction with accompanying drawing, describe the utility model content in detail:
Embodiment one:
Consult shown in Fig. 1 and Fig. 4, the diaphragm of loudspeaker is rectangle vibrating diaphragm, comprises ring portion 1, and ring portion 1 comprises two the major axis portions 2 and two minor axis portions 3 that lay respectively at offside, is provided with the bight 4 of vibrating diaphragm between adjacent major axis portion 2 and minor axis portion 3.
As shown in Figure 5, the height in the bight 4 in ring portion 1 is d2, and the height in major axis portion 2 and minor axis portion 3 is equal, is d1, the height in the height in bight 4 and major axis portion 2, minor axis portion 3 not etc., i.e. d2 ≠ d1, and d2 < d1.
Preferably, the height in four bights 4 in ring portion 1 is equal, is d2, and operation is relatively simple, is convenient to realize.
Preferably, the diaphragm of loudspeaker of the present utility model comprises upper and lower two-layer substrate layer, and substrate layer is polyetheretherketonematerials materials layer; Glue-line is provided with, by fixing for two-layer polyetheretherketonematerials materials layer bonding between substrate layer.
Preferably, the diaphragm of loudspeaker of the present utility model is the composite construction of polyetheretherketonematerials materials layer and Thermoplastic polyurethane elastomer material layer.
Pass through technique scheme, four bights in ring portion 1 and major axis portion 2, minor axis portion 3 adopt not contour design, make the design in bight 4 more flexible and diversified, be more convenient for debugging better properties of product, contribute to the reliability improved product distortion, Optimal performance and improve product.
Embodiment two:
Fig. 6 and Fig. 7 collectively illustrates second embodiment of the utility model vibrating diaphragm, and the present embodiment is substantially identical with embodiment one, and its difference is:
The height in four bights 4 in ring portion 1 is d3, and d3 > d1.
That is, the diaphragm of loudspeaker of the technical program, the height in four bights 4 in ring portion 1 can be greater than the height in major axis portion 2, minor axis portion 3, also can be less than the height in major axis portion 2, minor axis portion 3, above, does not all affect the enforcement of the technical program.
These are only the utility model case study on implementation, be not limited to the utility model, as long as those of ordinary skill in the art modify or change according to the equivalence that the utility model institute disclosure is done, all should include in the protection range recorded in claims.
