Diaphragm and loudspeaker

Abstract

The invention discloses a vibrating diaphragm and a loudspeaker, the vibrating diaphragm comprises a central part and a folding ring part, and the folding ring part is connected to the outer peripheryof the central part and extends along the circumferential direction of the central part to form a ring shape. The folding ring part comprises a long shaft section, a short shaft section and an arc-shaped section for connecting the long shaft section and the short shaft section, and the length of the long shaft section is larger than that of the short shaft section. The long-axis section is wavy and is provided with a plurality of first wave crests and a plurality of first wave troughs which are arranged in the length direction of the long-axis section. According to the technical scheme, the stress concentration phenomenon of the folded ring part of the vibrating diaphragm can be reduced, and the performance reliability of the loudspeaker is improved.

Description

technical field [0001] The invention relates to the technical field of sound energy conversion, in particular to a diaphragm and a loudspeaker. Background technique [0002] When the compliance and amplitude of the speaker diaphragm are relatively large, in addition to the severe vibration of the four corners of the diaphragm, the vibration of the long-axis surround and the short-axis surround is also very severe. Moreover, in some products with a larger length ratio between the long-axis surround and the short-axis surround, the vibration of the long-axis surround is more severe. When vibrating, large-amplitude pulls cause vibration imbalance and stress concentration on the surround, which affects the reliability of the diaphragm and is prone to membrane rupture or delamination, thereby affecting the acoustic performance of the speaker. Contents of the invention [0003] The main purpose of the present invention is to provide a diaphragm, aiming at reducing the stress co...

Moreover, in some products with a large length ratio between the long-axis surround and the short-axis surround, the vibration of the long-axis surround is more severe

When vibrating, the ring is prone to vibration imbalance and stress concentration due to large-amplitude pulling, which will affect the reliability of the diaphragm, and it is prone to membrane rupture or delamination, which will affect the acoustic performance of the speaker.
