摘要

It is necessary to use dynamic speaker for some cellular phones to achieve high quality sound A dynamic speaker, a mechanical component in personal communication devices, needs to be smaller, lighter and flatter in its frequency responses. In this paper, a design tool considering mechanical and electromagnetic coupling effects is proposed using finite element method and confirmed by experiments. After a sensitivity analysis of mechanical and electromagnetic design parameters, a new design is also proposed with wider frequency range and higher sound pressure level.
