From the above description, the beneficial effects of the utility model are as follows: by arranging the pattern group 21 with the convex pattern 211, the compliance of the vibrating diaphragm in the vibrating process is improved, the polarization is improved, so that the distortion is improved, meanwhile, the convex pattern 211 is provided with a pattern plane 2111, the distortion improving effect is further improved, and the sound quality of a loudspeaker applying the vibrating diaphragm is improved.

Further, the annular portion 2 is rectangular, and the pattern group 21 is provided at each corner of the annular portion 2.

As is clear from the above description, the corner portions of the folded ring portion 2 are provided with the pattern groups 21, which is advantageous in improving the compliance of the corner portions of the diaphragm, thereby improving the acoustic performance of the diaphragm.

Further, the two pattern groups 21 of the folded ring portion 2 on the same major axis side or the same minor axis side are symmetrically arranged.

As is clear from the above description, this structure is advantageous in that the diaphragm is more stable when vibrating.

Further, the number of the raised patterns 211 in the pattern group 21 is 12.

As can be seen from the above description, increasing the number of the raised patterns 211 in the pattern group 21 is beneficial to further improving the compliance of the diaphragm.

Further, in the pattern group 21, the pitch of the adjacent two convex patterns 211 near the end of the fixing portion 3 is larger than the pitch near the end of the central portion 1.

As is apparent from the above description, this structural arrangement improves the compliance of the diaphragm on the one hand, and on the other hand, since the voice coil is connected to the center portion 1, the stress at the connection of the center portion 1 and the gimbal portion 2 is concentrated during vibration, and thus the structural arrangement is also advantageous for dividing the stress of the stress concentrating region.

Further, the width of the convex pattern 211 gradually increases from both ends thereof to the middle thereof.

Further, the convex pattern 211 extends from an end near the center portion 1 to an end near the fixing portion 3.

From the above description, the arrangement of the structure improves the compliance of the diaphragm, and effectively suppresses polarization, thereby improving the stability and acoustic performance of the diaphragm.

Further, the pattern planes 2111 of the plural raised patterns 211 are located on the same plane.

Further, the pattern plane 2111 is tangential to the top of the turn-up portion 2.

As can be seen from the above description, the pattern planes 2111, which are plural in number, are located on the same plane and are tangential to the top of the folded ring portion 2, so that on one hand, the compliance of the diaphragm is further improved, and thus the distortion is improved, and on the other hand, a sufficient margin of vibration is given above the diaphragm to ensure the amplitude, and the sound quality of a speaker to which the diaphragm is applied is improved.

A loudspeaker comprises the vibrating diaphragm.

From the above description, the diaphragm is applied to a loudspeaker, so that the sound quality of the loudspeaker can be effectively improved.

Example 1

Referring to fig. 1, a first embodiment of the present utility model is as follows: a vibrating diaphragm and a loudspeaker with the vibrating diaphragm are applied to terminals such as mobile phones, flat plates, game palm machines and the like.

The vibrating diaphragm comprises a central part 1, a folded ring part 2 and a fixed part 3 which are sequentially connected from inside to outside, wherein the folded ring part 2 is provided with a plurality of pattern groups 21, each pattern group 21 comprises a plurality of convex patterns 211 which are arranged at intervals, and the top of each convex pattern 211 is provided with a pattern plane 2111. The diaphragm is provided with compliance by stretching and shrinking the material, deformation of the diaphragm can influence the compliance of displacement of the diaphragm after being stressed, and the compliance of the diaphragm can be effectively improved by arranging the convex pattern 211 and the pattern plane 2111, namely, the distortion of the diaphragm in the vibration process is improved. In addition, by adjusting the arrangement and number of the convex patterns 211, the problem of wrinkling and folding of the folded ring portion 2 can be improved, thereby suppressing polarization and further improving the effect of improving distortion.

Specifically, the ring-folding portion 2 is rectangular, and the pattern group 21 is disposed at each corner of the ring-folding portion 2. The corners of the folded ring part 2 are areas where stress is concentrated when the vibrating diaphragm vibrates, and the pattern groups 21 are arranged at the corners, so that the compliance of the corners of the vibrating diaphragm can be better improved, and the stress can be split; in addition, since the corner portions of the folded ring portion 2 are extremely likely to have wrinkles or folds, which results in high distortion, and the folded ring portion 2 is fatigued and is unlikely to pass the reliability test, the problems can be improved by this arrangement.

Preferably, the two pattern groups 21 of the folded ring part 2 on the same long axis side or the same short axis side are symmetrically arranged, and the arrangement of the structure ensures that the compliance of each corner part of the vibrating diaphragm is kept consistent, which is beneficial to ensuring the stability of the vibrating diaphragm in the vibrating process.

Alternatively, the number of the raised patterns 211 in the pattern group 21 is 12. The number of the convex patterns 211 is gradually increased, the compliance of the diaphragm is further improved, and a corresponding number of the convex patterns 211 can be set according to the available space on the folded ring part 2 and the actual requirement.

Preferably, in the pattern group 21, a distance between two adjacent raised patterns 211 near one end of the fixing portion 3 is larger than a distance between two adjacent raised patterns near one end of the central portion 1. The voice coil in the central part 1 and the loudspeaker are connected, the joint of the folded ring part 2 and the internal fixing part 3 is also a stress concentration area, the distance between the convex patterns 211 close to the central part 1 is reduced, the convex patterns 211 are gathered relatively in the stress concentration area, the stress is effectively divided, the compliance of the vibrating diaphragm in the vibrating process is further improved, and therefore the distortion is reduced.

Preferably, the width of the convex pattern 211 is gradually increased from both ends to the middle thereof, further improving the compliance of the diaphragm.

Preferably, the convex pattern 211 extends from an end near the center portion 1 to an end near the fixing portion 3, which improves the compliance of the diaphragm on the one hand and suppresses polarization on the other hand, which is advantageous in improving the stability and acoustic performance of the diaphragm.

Example two

Specifically, through the above-mentioned structure setting, on the one hand improved the compliance of vibrating diaphragm to improve the distortion, the other party has given the vibration allowance that is enough above the vibrating diaphragm, guarantees the amplitude of vibrating diaphragm. Preferably, the pattern plane 2111 is tangent to the top of the folded ring portion 2, that is, the maximum vibration margin is provided above the diaphragm, so that the maximum amplitude of the diaphragm is ensured, and the sound quality of the loudspeaker is improved.

In summary, the diaphragm and the loudspeaker provided by the utility model have the advantages that the pattern group with the convex patterns is arranged, so that the compliance of the diaphragm in the vibration process is improved, the problem of polarization of the diaphragm is solved, the distortion is improved, and meanwhile, the convex patterns are provided with pattern planes, so that the distortion improving effect is further improved; in addition, the pattern groups are symmetrically arranged on the folded ring part and span the folded ring part, so that the stress of the vibrating diaphragm can be effectively balanced, the polarization is improved, the pattern plane is tangent to the top of the folded ring part, the maximum amplitude of the vibrating diaphragm is ensured, and the loudspeaker applying the vibrating diaphragm is beneficial to improving the tone quality and stability.
