Piezoelectric buzzer: piezoelectric buzzer uses piezoelectric ceramic buzzer to generate positive and negative movement direction under the action of external changing electric field, so as to produce deformation and sound. When installed in the external resonance box to form a buzzer, the sound can be increased!
Advantages and characteristics of piezoelectric buzzer: low power consumption, low current, wireless ring contact, so it has long service life, no noise, thin thickness, wide frequency range and no magnetic field.
At present, the main products in the market are turning to energy saving, high loudness and low current. Integrating various requirements, piezoelectric buzzer will be applied in more fields.
