Multi-Layered Piezo Speaker

PUI Audio’s piezo speakers with frequency ranges from 300 to 20,000 Hz

Image of PUI Audio Inc's Multi-Layer Piezo SpeakersLess than 1.5 mm deep, PUI Audio's multi-layer piezo speakers reproduce sound, voice, and music. These ultra-thin speakers are available in four styles to suit many applications.

The APS3008S-R is mounted in a stainless steel chambered housing for increased sound output and performance.

The APS2718S-T-R has double-sided adhesive tape designed to optimize sound for maximized performance when flat panel mounted.

Two sizes, the APS2509S-T-R and APS2709S-T-R, are offered without a stainless steel housing to aid in space-saving. They are fitted with a thicker double-sided adhesive which automatically chambers sound output after mounting.

Each style offers a wide frequency range of 300 to 20,000 Hz along with the low current draw of traditional piezo devices. The small size of these speakers allows them to be mounted on touch panel displays, camera equipment, and other handheld devices where other devices would be too thick.
