  • Multilayered electrostatic transducer
    Patent number: 12707206
    Abstract: An electrostatic transducer includes first and second flexible conductive membranes; and first and second conductive stators. The membranes and the stators are assembled in a layered configuration with the membranes between the stators and with an enclosed volume of air sealed between the first and second membranes. The electrostatic transducer is arranged in use to apply an electrical potential which gives rise to an electrostatic force between the membranes and the stators that causes the membranes to move relative to the stators.
