This simple STM setup utilises a piezoelectric actuator constructed by deliberately cutting a piezo speaker into four quadrants. With individual drive wires attached to the four quadrants.

Will piezoelectric-based speakers replace traditional speakers over the coming years in space-constrained devices? We have definitely seen the use of piezo transducers in e.g. high-end televisions … ...

Trends, opportunity and forecast in the global piezoelectric speaker market from 2017 to 2028 by product type (active piezo and passive piezo), application (automotive electronics, alarm, toy ...

KYOCERA Develops Ultra-Thin, Lightweight 'Piezo Film Speaker' for TVs, PCs, Tablets High audio quality "Smart Sonic Sound" utilized in flat-screen TV for first time ...

Kyocera Corporation has combined a piezoelectric actuator with a special resin film to produce Smart Sonic Sound – a piezo film speaker that is thinner and lighter than conventional speakers yet ...

The vibrating piezoelectric film moves the surrounding air, thus producing sound. Increasing the voltage across the speaker increases the piezo element deflection, creating more sound pressure and ...

The Piezo Film speakers are thinner that paper and measure just 80 microns thick yet are capable of producing rich sounding audio and are now available to back over on the Kickstarter ...

We first started reporting on the world's first solid-state speakers in early 2023, but xMEMS has been around since 2018. During that time, it has been using MEMS to make miniature piezoelectric ...

Piezoelectric speaker will let researchers talk with dolphins. A team of Japanese researchers from the Tokyo University of Marine Science and Technology may become the first people to communicate ...

Current ceramic speakers available on the market have a capacitance on the order of 1 μF. The impedance of the speaker is 20 Ω at 8 kHz and 10 Ω at 16 kHz. Future ceramic speakers may have a larger ...
