The most comprehensive and advanced piezo driving technology, addressing wearables, smartphones, tablets, TVs and automotive. PiezoDrive™ is not just a piezo driver IC product line: it’s a complete system solution, from DSP to amplifier to transducer, ready to produce sound through any surface you can think of.
Up to 80% power reduction, increasing average battery life span.
Piezo vs dynamic speaker: less power use
Piezoelectric speakers require high voltage and low current: modeled as capacitive.
Dynamic speakers require high current and lower voltage: modeled as inductive + resistive.
Using the display panel as a transducer, the technology produces sound in high quality directly from the screen eliminating the classic micro-speakers.
Possibility to make the device 100% waterproof with the complete removal of the holes of the dynamic speakers (e.g. smartwatch).
Detects pressure level: touch recognition with direct haptic feedback for a unique and full immersive user experience.
Thin, the vibration replaces traditional speakers and LRA motor saving space. More space for battery.
Suitable for portable devices with display (smartphones, tablets, laptops, smartwatches) and any surface.
Piezo transducers can be attached to any surface (e.g. display) via double sided tape or other methods.
Speakers: Piezoelectric material expands or shrinks when electric charge is applied.
Haptics: Piezoelectric material expands or shrinks in a very quick timing and can generate haptics feedback.
Force feedback: Piezoelectric material can be charge when material deforms.
IVM6303 and algorithms are uniquely designed to drive a piezo transducer, producing sound as a traditional dynamic speaker would.
Vibrational modes on a surface excited by a piezo.
Sound pressure generated by the vibration of the surface by means of the implementation of the piezoelectric.
