Abstract

The embodiment of the invention provides a loudspeaker diaphragm and a loudspeaker. The loudspeaker diaphragm comprises a central portion, a folding ring portion and a fixing portion, which are sequentially connected from the inside to the outside; and a plurality of patterns across the folding ring portion and the fixing portion are arranged on the diaphragm; and the first end of each pattern extends toward the peripheral edge of the fixing portion, and the second end of the pattern extends out from the peripheral edge of the folding ring portion to extend onto the folding ring portion. The technical scheme provided by the invention can not only effectively divide the stress of a stress concentration region of the fixing portion but also can increase the strength of the fixing portion, thereby effectively avoiding the problem of warpage and deformation after the diaphragm is formed, and improving the diaphragm yield.

Description

technical field [0001] The invention belongs to the technical field of electroacoustic conversion devices, in particular, the invention relates to a loudspeaker diaphragm and a loudspeaker. Background technique [0002] A speaker is a device that converts electrical energy into sound energy, and is widely used in electronic devices such as mobile phones and computers. [0003] The diaphragm is the core generating part of the speaker. The diaphragm generally includes a central part, a ring part and a fixing part, and the diaphragm is fixed on the housing of the speaker through the fixing part. At present, the design of the compliance performance of the diaphragm is getting more and more limited. Therefore, it is necessary to increase the width of the ring part by reducing the width of the fixed part, so as to improve the compliance performance of the diaphragm. However, the design of the ring part will cause stress concentration in the fixed part, and coupled with the reduct...
