  • Methods and apparatuses for driving audio and ultrasonic signals from the same transducer
    Patent number: 11856366
    Abstract: Driver circuitry is disclosed for driving an electroacoustic transducer to provide an output comprising both ultrasonic and audio signal components. The driver circuitry comprises an adjustment module configured to reduce the level of said ultrasonic component signal in response to an increase in an operational variable indicative of a level of said audio signal component, while also increasing the pulse duration, duty cycle, repetition frequency or frequency span or bandwidth of the ultrasonic component.
    Type: Grant
    Filed: October 26, 2020
    Date of Patent: December 26, 2023
    Assignee: Cirrus Logic Inc.
    Inventors: John Paul Lesso, Cedric Andrieu, Calum Cuthill
