PZ1000K071
Ultrathin 0.15mm Piezo Disc Piezo Diaphragm for Buzzer
Dimension:
Diameter: 15mm±0.5
Thickness: 0.15mm±0.03
Electrode: Silvering silvering
Radial frequency Fr:135 KHz ± 10KHz
Operating temperature:-20~ +70
Storage temperature:-30~ +80
range of piezo disc to produce:
Diameter: 2mm-120mm
Thickness:0.1mm-30mm
Application:
Piezoelectric buzzers, or piezo buzzers, as they are sometimes called, were invented by Japanese manufacturers and fitted into a wide array of products. A buzzer or beeper is an audio signalling device, which may be mechanical, electromechanical, or piezoelectric (piezo for short). Typical uses of buzzers and beepers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke.
A piezoelectric element may be driven by an oscillating electronic circuit or other audio signal source, driven with a piezoelectric audio amplifier. Sounds commonly used to indicate that a button has been pressed are a click, a ring or a beep.Interior of a readymade loudspeaker, showing a piezoelectric-diskbeeper (With 3 electrodes ... including feedback electrode ( the central, small electrode joined with red wire in this photo), and an oscillator to selfdrive the buzzer.A piezoelectric buzzer/beeper also depends on acoustic cavity resonance or Helmholtz resonance to produce an audible beep.
