Summary:
Loud speakers, which are representative transducers, have non-linearity, thus that requires for speaker researchers to measure loud speakers precisely. In particular, micro-speakers, which are used in potable devices as smartphones, have poor situation for generating sound compared to other sound emitting objects. Thus, more careful measurement is necessary. In this paper, the effect of heating coil through the pre-driver in the micro-speakers with a voice coil is presented. The experimental results related to coil heating is shown, and from the result, we can know coil heating is necessary for precise measurement of micro-speakers.
