Multi-Diaphragm Micro-Speaker Vs. Single-Diaphragm Micro-Speaker

EasyChair Preprint 8147

Abstract

With wearable devices becoming increasingly popular, there is a foreseen paradigm shift for small format or miniature audio transducers in the near future. Small single diaphragm micro-speaker transducer no longer meets the new expectations both in low frequency performance and overall sound pressure level. In this paper a new multi-diaphragm micro-speaker is presented. The acoustic performance of the transducer is simulated using COMSOL Multiphysics. Furthermore, this paper analyzes the low frequency performance between the single diaphragm micro-speaker and the multi-diaphragm micro-speaker.

Keyphrases: Impedance, Radiation, SPL, audio transducer, loudspeaker, wearable，
