We have theoretically and experimentally analyzed microphones with cylindrical and spherical polyvinylidenefluoride diaphragms. In particular, the response of such microphones to airborne sound and to vibrations as a function of diaphragm geometry, acoustic impedance of the surrounding medium, coupling volume, and excitation was calculated. Most importantly, a relationship between the output voltage at low frequencies and the position of resonant frequencies was established. There is good agreement between calculated and measured frequency responses.
