Problems solved by technology

The diaphragm of a traditional sounder extends outward at the edge of the ring to form a fixed part for fixing with the sounder shell, resulting in a larger size of the diaphragm in the X and Y axis directions, but the effective vibration of the diaphragm The area (Sd) is small, and the acoustic performance of the sounder will also be affected; and in the actual application of the sounder module, the structure of the fixed part has many limitations on the design of the signal lead-out structure
If the size of the fixed portion of the diaphragm is reduced, the bonding strength between the diaphragm and the shell will be affected, and the overall performance of the sounder will be affected

Abstract

The invention discloses a vibrating diaphragm and a sounder monomer comprising the same, and relates to the technical field of electroacoustic products, wherein the vibrating diaphragm comprises a central part, a folding ring part arranged around the central part and a fixing part integrally arranged with the folding ring part; the fixing part comprises a vertical part which extends downwards fromthe outer side edge of the folding ring part; the invention also discloses a sounder monomer comprising the vibrating diaphragm. According to the vibrating diaphragm and the sounder monomer comprising the same provided by the invention, the effective vibration area of the vibrating diaphragm can be remarkably increased, and the acoustic performance of a sounder product is improved.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products. More specifically, it relates to a vibrating membrane and a sound generator unit including the same. Background technique [0002] The sound generator is an important acoustic component of portable electronic equipment, which is used to complete the conversion between electrical signals and sound signals, and is an energy conversion device. The miniature sounder usually includes a sounder shell and a vibration system and a magnetic circuit system contained in the sounder shell. The magnetic circuit system includes a magnetic yoke, and the inner center of the magnetic yoke is sequentially fixed with a central magnet and a central magnetic plate. The vibration system includes a diaphragm and a voice coil. The voice coil surrounds the center magnet and the center magnetic plate, and moves up and down along with the alternating audio signal passing through it, thereby driving the di...
