摘要

This paper describes a microspeaker (composed of a mechanically polished PZT bimorph diaphragm and bulk-micromachined silicon top cover) that shows flat diaphragm displacement from DC to 16kHz. The microspeaker with an encapsulating cylindrical package of about 0.5cc inside volume produces sound pressure level (SPL) of 103.6 ~ 110 dB between 1.3 and 12 kHz when measured 5 mm away from the diaphragm with 190Vpeak-topeak sinusoidal driving signal.
