Vibration diaphragm and loudspeaker provided with same

Abstract

The invention discloses a vibration diaphragm and a loudspeaker provided with the same and belongs to the electro acoustic product technical field. The vibration diaphragm comprises a frame; the frame is provided with an edge portion, a folding ring portion and a center portion which are distributed from outside to inside sequentially and are connected with one another to form an integrated body; a plurality of open holes are distributed in the folding ring portion; the outer side of the frame is provided with a film coated layer; the frame and the film coated layer are both made of polymer materials; the material hardness of the fame is greater than that of the film coated layer; and the material of the film coated layer has elasticity. With the vibration diaphragm and the loudspeaker provided with the same of the invention adopted, technical problems such as little possibility of realizing smoothness adjustment of a vibration diaphragm in the prior art can be solved. The smoothness adjustment of the vibration diaphragm of the invention is flexible; the stiffness coefficient distribution space of the vibration diaphragm is large; the stability and reliability of the vibration diaphragm are higher; and therefore, with the vibration diaphragm adopted, the acoustic performance of the loudspeaker can be excellent, the sound quality of the loudspeaker is high, and the service life of the loudspeaker is long, and people's requirements for high sound quality of electronic equipment can be satisfied.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a vibrating membrane and a loudspeaker provided with the vibrating membrane. Background technique [0002] The loudspeaker is an important acoustic component in portable electronic equipment, which is used to convert sound wave electrical signals into sound signals, and is an energy conversion device. Loudspeakers usually include a vibration system and a magnetic circuit system. The vibration system includes a combined diaphragm and voice coil. The diaphragm includes an edge part, a ring part and a ball top that are sequentially combined from the outside to the inside. The diaphragm is an important part of the speaker. The loudspeaker's sound reproduction performance plays a vital role, which determines the conversion quality of the loudspeaker from electrical energy to sound energy.

AI Technical Summary

Problems solved by technology

[0003] The existing diaphragm is usually made of a single-layer or multi-layer plastic sheet. When the diaphragm is made of a single-layer plastic sheet, its compliance is good, but its heat resistance is poor, its rigidity is poor, and it is easy to deform and break ; When the diaphragm is made of multi-layer plastic sheets, its rigidity is good, but its compliance is poor

Therefore, it is difficult to achieve a balance between the rigidity and compliance of the existing diaphragm, and it is difficult to adjust. The comprehensive performance of the diaphragm is poor, and it is difficult to meet people's requirements for high sound quality of electronic equipment.
