    Introduction to the structure and principle of piezoelectric diaphragm buzzer
    The piezo sounder ceramic element buzzer is a piezoelectric ceramic crystal that is pressed by a high pressure and adhered to a vibrating metal piece. When an AC voltage is applied, mechanical deformation stretching and contraction occur due to the piezoelectric effect, and this characteristic is us

    The basic principle of piezoelectric ceramic buzzer and the application of piezoelectric buzzer
    Piezoelectric ceramic buzzer is a device used in piezoelectric ceramic sheets. It is more common to form titanium and piezoelectric ceramic sheets (pzt) sintered with zirconium and lead oxides. Since the human ear is most sensitive to the audio signal of 3khz, the resonant frequency of the piezo ele

    The acoustic range of piezoelectric ceramic element buzzer and the audio design of piezoelectric ceramic buzzer
    Piezo element film buzzer In general, a human's audio range is between approximately 20 Hz and 20 kHz. The most audible audio is 2kHz to 4kHz.Therefore, most piezoelectric sound elements are used in this audio range. At the same time, the buzzer resonance frequency (f0) is generally selected to be

    Electroacoustic component - piezoelectric ceramic pronunciation chip
    Piezo sounder ceramic element is a piezoelectric ceramic that can vibrate and sing under the excitation of an alternating electric field after being bonded to a metal substrate. However, because the acoustic impedance of the air does not match, the sound emitted is very small; the high-decibel buzze
