大きさにした超音波セラミックマイクロホン。A bimorph oscillator is constructed by attaching a diaphragm with a larger diameter to one side of a piezoelectric ceramic oscillator with lead wires connected to electrodes formed on both sides, and a conical oscillator on the surface of the diaphragm. Installation: Glue the above bimorph vibrator to the cylindrical protrusion of the mounting base using elastic adhesive.
The lead wire is inserted into a slit formed from the edge of the mounting base and fixed with adhesive, and the bimorph vibrator, conical vibrator, and mounting base are housed in a case, and the case is in the conical shape. An ultrasonic ceramic microphone whose size is such that the tip position of the vibrator is approximately equal to the position of the through hole formed in the case.
