Voice coil support for miniature loudspeakers

Abstract

A voice coil support for a miniature loudspeaker includes a support body and a dome. The support body includes a longitudinal connecting portion, a transverse dome connecting portion, and a transverse voice coil connecting portion. The dome is located at the center of the diaphragm and is connected to the transverse dome connecting portion. This allows the transverse voice coil connecting portion to be connected to the top of the voice coil, enabling the support body to be positioned between the voice coil and the diaphragm. This ensures that the entire voice coil is within the effective magnetic field region during operation, thereby maximizing the electromagnetic force between the voice coil and the magnetic return assembly, thus improving sound quality and volume.

Claims
