Ultrasonic piezoelectric speaker application:

The ultrasonic piezoelectric speakers are commonly employed to generate sound in digital quartz watches and other electronic devices, and they are also utilized as tweeters in less-expensive speaker systems like computer speakers and portable radios. They’re also used for ultrasonic animal repellers.

Piezoelectric speakers advantages:

Piezoelectric speakers have numerous advantages over traditional loudspeakers: they are resistant to overloads that would ordinarily damage most high-frequency drivers, and their electrical qualities allow them to be utilized without a crossover.

There are drawbacks as well: some amplifiers can oscillate while driving capacitive loads, such as most piezoelectrics, resulting in distortion or amplifier damage.

Furthermore, in most situations, their frequency response is worse than that of other technologies, particularly in the bass and midrange. As a result, they’re most commonly employed in situations when volume and high pitch are more crucial than sound quality.
