What Are Piezoelectric Earphones?

- Aug 14, 2018-

Piezoelectric earphones: use the piezoelectric effect of piezoelectric ceramics to make sound. Advantages: high efficiency and high frequency. Disadvantages: large distortion, high driving voltage, poor low-frequency response, and poor resistance to shock. These earphones are mostly used for telegraph transmission and reception, and are now basically eliminated. A small number of headphones use piezoelectric ceramics as a high-pitched sound unit.
