Abstract

The present invention discloses a miniature sound production device. The device comprises a vibration system consisting of a voice coil and a centering disk made of an insulating material; the centering disk comprises a central portion located at the center, an edge portion located at the periphery, and a cantilever located between the central portion and the edge portion; one end of the voice coil in an axial direction is fixed at the central portion; the voice coil comprises a body portion and a lead wire, the lead wire is led out along the cantilever and is fixed on the cantilever; the centering disk is a single-layer structure made of one material layer; or, the centering disk is of a multi-layer structure composed of a plurality of material layers or a multi-layer structure composed of a plurality of material layers and glue layers, and the material layers are made of the same material or different materials; the material layers are made of a high molecular polymers; and the thickness of the centering disk is 8 to 225 microns.

Description

technical field [0001] The present invention relates to the technical field of electroacoustic conversion, and more particularly, relates to a miniature sound generating device. Background technique [0002] Miniature sound generating devices usually include a vibration system and a magnetic circuit system. The vibration system includes a diaphragm and a voice coil. One end of the voice coil is fixed at the center of the diaphragm, and the other end is inserted into the magnetic gap of the magnetic circuit system. Miniature sound-generating devices face the problem of polarization. An increase in volume will increase the polarization amplitude of the vibration system, resulting in a loss of sound quality. To reduce polarization, in some instances, the vibration system is provided with a damper. The spider is fixed between the diaphragm and the voice coil. The damper creates an elastic support force that effectively reduces polarization. [0003] Existing dampers are usu...
