  • Piezoelectric buzzer with circuit elements mounted on nodal areas
    Patent number: 4600851
    Abstract: A piezoelectric buzzer includes a tone generator formed by bonding, to a resilient thin plate, a piezoelectric element having deposited thereon thin film electrodes, and an oscillation circuit formed by electronic parts connected to the electrodes. A conductive carrying area of a predetermined pattern is formed on the upper surface of the piezoelectric element along nodal points of vibration of the tone generator, and the electronic parts are fixedly mounted on the carrying area to constitute the oscillation circuit.
