For rectangular speaker vibrating diaphragm, the width of surround entirety mainly comprises the width of long and short axle ring and the width of ring corner.Existing rectangle vibrating diaphragm, the width of its ring corner and long and short axle ring is commonly wide design, and this kind of design can meet the demand that miniature loudspeaker power is less, vibrational system amplitude is less.But, along with the increase of product power and vibrational system amplitude, some speaker products are when amplitude is larger, had higher requirement for the resistance to tension of vibrating diaphragm in reliability and film fold ability, and the wide design of above-mentioned existing vibrating diaphragm can not meet speaker product at the performance of high-power lower work and reliability requirement.
Therefore, be necessary to improve the structural design of vibrating diaphragm, the demand to properties of product and reliability aspect when relatively high power works can be met.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of diaphragm of loudspeaker, by the improvement designed ring overall width, improves the resistance to tension of vibrating diaphragm and solves film pleat problem.
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; Bight is respectively arranged with between adjacent described major axis portion and described minor axis portion; The width in described bight and described major axis portion, described minor axis portion is not etc.
Improve as one, the width in described bight is greater than the width in described major axis portion, described minor axis portion.
Improve as one, described major axis portion is equal with the width in described minor axis portion.
Improve as one, four bight width in described ring portion are equal.
Improve as one, 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.
Improve as one, 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, four bights in its ring portion and major axis portion, minor axis portion is not wide design, the width of corner ring is greater than length, the width of minor axis ring, ring width under highly constant prerequisite in corner increases, be equivalent to the length increasing corner ring, reduce the stress of corner ring, this design can improve the resistance to tension of the diaphragm of loudspeaker, film pleat problem can be solved simultaneously, when loud speaker works in relatively high power, vibrational system amplitude is larger, the diaphragm of loudspeaker of the present utility model can meet the performance of speaker product and the demand of reliability aspect.

Reference numeral wherein comprises: 1, ring portion, 11, major axis portion, 12, minor axis portion, 13, bight.
Embodiment
Below in conjunction with accompanying drawing, describe the utility model content in detail:
Embodiment:
Consult shown in Fig. 1, Fig. 2 and Fig. 3, the diaphragm of loudspeaker of the present utility model is rectangular configuration, comprises ring portion 1, wherein, ring portion 1 comprises two the major axis portions 11 and two minor axis portions 12 that lay respectively at offside, is respectively arranged with bight 13 between adjacent major axis portion 11 and minor axis portion 12.
The diaphragm of loudspeaker of the present utility model, the width in the width in its bight 13 and major axis portion 11, minor axis portion 12 is unequal.Consult Fig. 4, Fig. 5 and Fig. 6 jointly shown in, major axis portion 11 is d1 with the width in minor axis portion 12, and the width in bight 13 is d2, wherein, d1 ≠ d2.
During concrete enforcement, the width d2 in bight 13 is greater than the width d1 in major axis portion 11, minor axis portion 12, this is because this kind of structural design is when the whole height in surround portion 1 is constant, the width increasing bight 13 is equivalent to the length increasing four bights 13, reduce the stress of corner ring, thus improve the resistance to tension of the diaphragm of loudspeaker, film pleat problem can be solved simultaneously, when loud speaker works in relatively high power, vibrational system amplitude is comparatively large, can meet the performance of speaker product and the demand of reliability aspect under this kind of situation like this.
Preferably, major axis portion 11 is equal with the width in minor axis portion 12, consult shown in Fig. 4 and Fig. 5, the width in major axis portion 11 and minor axis portion 12 is d1, that is, in the present embodiment, be only that four bights 13 in ring portion 1 are not wide design with major axis portion 11, minor axis portion 12, but two major axis portions 11 and two minor axis portions 12 are wide design.
Preferably, the width in four bights 13 in ring portion is equal, consult shown in Fig. 6, the width in bight 13 is d2, that is, in present embodiment, the width in bight 13 is greater than the width in major axis portion 11, minor axis portion 12, but the width being arranged at four bights 13 between adjacent major axis portion 11 and minor axis portion 12 is equal.It should be noted that, during concrete enforcement, the width in four bights 13 also not can be designed as not etc., but itself and major axis portion 11 should be met, minor axis portion 12 is not wide design, and, preferred scheme is, the width in each bight all should be greater than the width in major axis portion 11, minor axis portion 12, is convenient to realize the technique effect that the diaphragm of loudspeaker of the present utility model will reach.
Preferably, the diaphragm of loudspeaker of the present utility model comprises upper and lower two-layer substrate layer, substrate layer is polyetheretherketonematerials materials layer (PEEK), is provided with glue-line between substrate layer, and two-layer polyetheretherketonematerials materials layer (PEEK) is fixing by middle glue-line bonding.That is, the diaphragm of loudspeaker can be the three-layer composite structure of PEEK+ glue-line+PEEK, and wherein, glue-line is filled by the material with damping characteristic.
Preferably, the diaphragm of loudspeaker of the present utility model is the composite construction of polyetheretherketonematerials materials layer (PEEK) and Thermoplastic polyurethane elastomer material layer (TPU).That is, the diaphragm of loudspeaker can also be the double-layer structure of PEEK+TPU.
It should be noted that, the exemplary illustration that the structure of above-mentioned two kinds of diaphragms of loudspeaker is only used to the technical program is described and makes, during concrete enforcement, the diaphragm of loudspeaker of the present utility model, its structure is not limited to above-mentioned two kinds of composite constructions, can also be other structure, concrete material composition not also be limit by this, as long as its four bights 13 meeting ring portion 1 are designed for not wide with major axis portion 11, minor axis portion 12.
