  • Patent number: 11936349
    Abstract: The present disclosure provides an audio circuit capable of inhibiting a current when mute is deactivated. An output terminal of a class D amplifier circuit is connected to an electroacoustic conversion element through a low-pass filter. An output node of a bridge circuit is connected to the output terminal. An integrator integrates and outputs, in a non-mute period in which a mute control signal is negated, a difference between an input signal and a feedback signal corresponding to an output signal generated at the output terminal, and outputs a predetermined bias voltage in a mute period in which the mute control signal is asserted. A PWM comparator compares the output of the integrator with a periodic voltage. A driver switches, in the non-mute period, the bridge circuit according to an output of the PWM comparator, and fixes an output of the bridge circuit in the mute period.

  • Patent number: 11910156
    Abstract: Implementations of the subject technology provide an acoustic module with fins integrated within the acoustic module to reduce acoustic noise. Airflow caused by pressure changes due to an oscillating diaphragm can be diverted by the fins within the acoustic module. The diverted airflow provide a more uniform airflow distribution within the acoustic module, which leads to a lower peak velocity and less unwanted noise. Fins may include a curved or crescent shape and may be spaced in a certain manner to divert the airflow.
