Description

Silicone diaphragm

technical field

The utility model relates to a silicone vibrating membrane, in particular to a design in which several convex ribs are provided on the inner surface of the hanging edge, and the center of gravity of each convex rib is located outside the center line of the hanging edge.

Background technique

The diaphragm consists of a center part and an edge part surrounding the center part. The center part is responsible for the treble, while the edge part is responsible for the bass; therefore, the center part should be thin and rigid, and the edge part should be soft enough to provide the vibration when the diaphragm moves. The required compliance, resilience, and proper damping are required to play the bass; however, since the diaphragms of thin speakers are very thin, if the strength of the hanging edge is not enough, the speaker cannot provide enough sound when it is subjected to high power. The force is controlled to exert a damping effect, causing the diaphragm to experience polarization distortion due to power intolerance.

Secondly, the current overhang adopts the hot pressing forming process, and the overhang of a diaphragm is formed by hot pressing, and in order to further change the strength and compliance of the overhang, some wrinkles are also set on the overhang surface , but because the wrinkles are formed by hot pressing, it is difficult to precisely control their size, resulting in unstable quality of the produced diaphragm, which will naturally affect the performance of volume and sound quality.

Utility model content

In order to solve the problem of unstable quality in the prior art, the utility model provides a silicone diaphragm, which has the effect of stable quality; it has the effect of strengthening the strength and compliance of the hanging edge, and improving the power of the speaker.

The technical scheme that the utility model solves its technical problem adopts is:

A silicone vibrating membrane, comprising a central portion, an edge portion surrounding the central portion, a joining portion connecting the central portion and the edge portion, and a fixing portion surrounding the periphery of the edge portion, and the edge portion has a flat surface , and there are several convex ribs on the inner surface of the hanging edge; wherein, the hanging edge is in a raised shape, and the center of gravity of each convex rib is located outside the center line of the hanging edge.

In addition, each of the convex ribs is gradually thickened in one direction from the inside to the outside of the hanging edge; wherein, the limit of the starting point of each of the convex ribs is the apex of the hanging edge, and the limit of the ending point of each of the convex ribs The limit is the outer peripheral edge of the hanging edge; or, the limit of the starting point of each rib is the inner peripheral edge of the hanging edge, and the limit of the ending point of each rib is the outer peripheral edge of the hanging edge. In addition, each of the convex ribs takes the apex of the hanging edge as the limit of the starting point, and gradually thickens toward the inner peripheral edge and the outer peripheral edge in two directions, and the thickness of the outer convex rib is larger than that of the inner convex rib. of thickening.

Furthermore, the height of the connecting portion is higher than or equal to the height of the fixing portion; the height of the fixing portion is higher than the height of the connecting portion; the apex of the hanging edge portion is located outside the central line.

Thereby, the inner surface of the hanging edge has several convex ribs, and the center of gravity of each of the convex ribs is located outside the center line of the hanging edge, and the strength and smoothness of the hanging edge are strengthened by each of the convex ribs. It is flexible and can be produced by injection molding technology. The product quality is very stable, and it has stable quality, strengthens the strength and compliance of the hanging edge, exerts a proper damping effect, and improves the power of the speaker.

The beneficial effect of the utility model is that it has the effect of stable quality; it has the effect of strengthening the strength and compliance of the hanging edge and improving the power bearing of the loudspeaker.
