Problems solved by technology

[0003] Better low-frequency characteristics can extend the acoustic performance of the micro-speaker to the lower frequency end, but the lower operating frequency will cause a larger vibration displacement of the diaphragm. At this time, the vibration system is prone to polarization problems and the sound caused by polarization. The problem of loose wires and broken wires caused by the rubbing of the ring against the magnetic circuit will reduce the reliability of the speaker and make the speaker prone to noise; at the same time, the diaphragm is prone to wrinkles at the parts where the stress is concentrated, and it is difficult to work under high-intensity conditions for a long time. In this situation, there is a risk of diaphragm deformation and film cracking, threatening the acoustic performance and reliability of the speaker system

Abstract

The invention discloses a vibrating diaphragm. The vibrating diaphragm comprises a centre part, a folding ring part and a fixed part, wherein the folding ring part surrounds the centre part; the fixed part is integrally arranged with the folding ring part; the folding ring part comprises a first straight folding ring part; the first straight folding ring part comprises two straight folding rings extending horizontally; a plurality of arc-shaped patterns are respectively arranged on the two straight folding rings; and the arc-shaped patterns are concave structures. By means of the vibrating diaphragm disclosed by the invention, polarization of the vibrating diaphragm under low-frequency and large displacement can be effectively inhibited; and thus, the reliability and the acoustic performance of a loudspeaker can be improved.

Description

technical field [0001] The present invention relates to the field of electroacoustics, and more specifically, to a vibrating membrane. Background technique [0002] In the prior art, the miniaturization of electronic terminal products such as mobile phones, tablet computers, and notebooks is increasingly obvious, and the accessories used are also increasingly miniaturized and flattened. Generally, the loudspeaker includes a shell, and a vibration system and a magnetic circuit system are arranged in the inner cavity surrounded by the shell. The vibration system includes a diaphragm and a voice coil connected together. Among them, the design of the diaphragm has always been an important factor in determining the performance of the micro-speaker system. As micro-speakers have higher and higher requirements for low-frequency characteristics, the problems faced by the diaphragm design are becoming more and more severe. [0003] Better low-frequency characteristics can extend the...
