Estimation of loudspeaker voice-coil dynamic temperature response
碩士 === 國立成功大學 === 機械工程學系 === 102 === The efficiency of moving coil loudspeaker is very low. Roughly around 5% of electricity energy is transformed to acoustic energy and loudspeaker failure is mainly due to high temperature of voice coil. In this thesis, loudspeaker's electric, mechanical, acou...

Roughly around 5% of electricity energy is transformed to acoustic energy and loudspeaker failure is mainly due to high temperature of voice coil. In this thesis, loudspeaker's electric, mechanical, acoustical and thermal behaviors have been studied, and the relationships between them have been discussed. The thesis focuses on the influence of Eddy current heating effect and convection cooling effect to the voice coil temperature. A conjugated FEM model is also raised.
