Piezo film speaker for sale

The piezoelectric film speaker is known by a variety of names, including piezo, buzzer, and crystal loudspeaker. It is, in essence, a speaker that generates sound using the piezoelectric effect. The initial mechanical motion is created by delivering a voltage to a piezoelectric material. Additionally, diaphragms and resonators are commonly used to translate motion into audible sound.

What is the definition of a piezo film speaker?

The piezoelectric speaker is known by a variety of names, including piezo, buzzer, and crystal loudspeaker. It is, in essence, a speaker that generates sound using the piezoelectric effect. The initial mechanical motion is created by delivering a voltage to a piezoelectric material. Additionally, diaphragms and resonators are commonly used to translate motion into audible sound. When compared to other speaker designs, piezoelectric speakers are relatively simple to drive. Piezoelectric speakers work effectively in the range of 1-5 kHz and up to 100 kHz in ultrasonic applications.
