Diodes Inc. has launched its PAM8907 piezoelectric sounder driver, designed to maximize the sound pressure level (SPL) from a ceramic/piezo sounder. The piezo sounder driver has a built-in synchronous ...

With its built-in boost converter, the PAM8907 piezoelectric sounder driver from Diodes is capable of driving a ceramic/piezo sounder with up to a 31-V PP output. The part maximizes sound pressure ...

Japan's Kyocera Corporation has combined a piezoelectric actuator with a special resin film to produce a proprietary, piezo film speaker that is considerably thinner and lighter than conventional ...

Like all ceramics, piezo ceramics are brittle materials that are well suited to handling compressive loads but are highly sensitive to bending, shear and tensile loads. A number of mechanical ...

The thinner our devices become, the less room there is for speakers and other thicker components. Kyocera has a solution, however: it just modified its Smart Sonic Receiver conduction technology for ...

Integrating a multi-mode charge pump boost converter, the PAM8904 from Diodes drives piezoelectric sounders at up to 18Vpp from a 3V power supply. Bringing higher volume at a lower operating current ...

Sporting a form-factor consistent with common piezo indicators, but generating roughly double the sound pressure, is how the company characterizes the KPI-800 family. The new 26-mm diameter by 22-mm ...
