<p>A ceramic microphone is described which comprises a diaphragm (4) for receiving sound waves, a thin ceramic plate (1) attached to the diaphragm (4) for transducing the sound waves to electric signals, and a plurality of electrodes (2a,2b,2c,2d;3a,3b,3c,3d) on each of the opposite aides of the ceramic plate (1), the plurality of electrodes being polarized so that each of a pair of the electrodes (2a,3a;2b,3b; 2c,3c;2d,3d) faces across the ceramic plate forms a capacitor and the opposite-polarity electrodes (2a,2b;2c,2d;3b,3c) of each of the capacitors are serially connected to each other.</p> |
