AI Technical Summary

Technical Problem

Traditional miniature loudspeakers struggle to meet the performance requirements of electronic devices in terms of low-frequency extension, low distortion, and high sensitivity, especially in low-frequency output.

Method used

The center mount design with rolled edges allows the voice coil to be moved down and arranged in a mirror symmetrical manner in the height direction, increasing the local thickness of the center mount and forming a recessed part as a channel and airflow channel, thus optimizing the spatial layout of the magnetic circuit unit.

Benefits of technology

It improves the low-frequency performance of the speaker, increases the effective amplitude, improves the driving force conversion factor and sound quality, and achieves better low distortion and high sensitivity.

Abstract

This disclosure relates to a loudspeaker assembly (100), characterized in that the loudspeaker assembly (100) comprises: a magnetic circuit unit (30), the magnetic circuit unit (30) including a top plate (36) and defining a magnetic gap (38); a support unit (20) connected to the magnetic circuit unit (30); and a vibration unit (10), the vibration unit (10) connected to the support unit (20) and including an upper diaphragm (12), a voice coil (14), and a center mount (16). The voice coil (14) extends at least partially into the magnetic gap (38), wherein the center patch (16) includes a center patch body (160) and at least two rolled edges (162, 164) surrounding the center patch body (160), wherein the center patch (16) abuts against the top side of the voice coil (14) by means of the rolled edges (162, 164), thereby positioning the top plate (36) of the magnetic circuit unit (30) in the height direction (z) at the center of the voice coil (14).
