Problems solved by technology

The shape of the existing sound cone is generally conical, and its conical surface is a smooth surface with low strength and high brittleness. It is easy to deform during long-term use, and it has a large effect on the division of sound, which is easy to cause sound distortion, thereby affecting to the effect of using the entire loudspeaker

Abstract

The invention provides a sound cone, which includes a polygonal star-shaped opening in the center, the edge of the opening extends obliquely upwards to form several V-shaped grooves whose sides are connected, and the concave part of the V-shaped groove has a straight line The side of the V-shaped groove is a straight second edge, and the first and second edges of several V-shaped grooves can extend downward and intersect at the same point. The sound cone of the present invention has a linear edge from the center to the outer edge, and compared with the existing conical sound cone, it has less influence on the linear motion of the voice coil, can effectively reduce the splitting effect on the sound, and has good rigidity , low distortion, and better sound quality of the generated sound.

Description

technical field [0001] The present invention relates to the technical field of loudspeakers, in particular to a sound cone. Background technique [0002] The sound cone is one of the important components used in speakers, and it mainly plays the role of sound radiation. The shape of the existing sound cone is generally conical, and its cone surface is a smooth curved surface, which has low strength and high brittleness. to the use of the entire speaker. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the defects of the prior art, and to provide a sound cone, which can reduce the division effect on the sound, and has good rigidity, low distortion and good sound quality. [0004] In order to achieve the above purpose, the present invention provides a sound cone, which includes a polygonal star-shaped opening in the center, and the edge of the opening extends obliquely upward to form several V-shaped grooves whose sides are connected. ...
