  • How to use FBelec External Drive piezo element? The piezoelectric buzzer is driven by an electrical signal from an external oscillating circuit such as a multi-frequency oscillator to generate sound. In this way, the piezoelectric sensor, acts like a loudspeaker. By properly suppressing the mechanical oscillation Qm of the piezoelectric basic element, a wider sound pressure frequency band can be obtained. This method is usually applied to the switching sound of household appliances, the keying sound of office automation equipment, the alarm sound of digital electronic watches, and the composite sound used in electronic games. In addition, it is also used in electric bells, transmitters, telephone receivers, card radios and speakers of LCD TVs. If you have technical questions, welcome to discuss, we look forward to your cooperation.
