Title:

INDEPENDENT TUNING OF AUDIO DEVICES EMPLOYING ELECTROACTIVE POLYMER ACTUATORS

Document Type and Number:

WIPO Patent Application WO/2014/160757

Kind Code:

A3

Abstract:

The disclosure provides a device (500) having first and second electroactive polymer actuators (5181,5182), each one of the electroactive polymer actuators comprising an electroactive polymer film, a pair of opposing compliant electrodes, and at least one mechanical output region. The mechanical output region is configured to move in response to an activation signal being applied to the electroactive polymer film to provide a movement. The first and second electroactive polymer actuators are independently tunable in frequency and amplitude to provide motion independently. Also disclosed are audio devices configured as over-the ear-headphones and in-the-ear headphones.
