Arcuately tensioned piezoelectric diaphragm microphone |
摘要 |
A lightweight piezoelectric microphone using a metallized piezoelectric diaphragm arcuately bowed by a boss on a slotted baffle plate held in close parallel proximity to the diaphragm is disclosed. Slotted Helmholtz resonators provide frequency response shaping and wide band noise cancellation. Electrical contact between the diaphragm and an electrical conductor is provided by a conductive, elastic material compressed by parts of the microphone housing, into electrical contact with the conductor and a metallized side of the diaphragm.
