  • Audio Amplifier
    Publication number: 20230402978
    Abstract: The present disclosure provides an audio amplifier circuit, including: a modulator circuit configured to modulate an audio input signal into a pulse width modulation (PWM) signal; a switch stage circuit configured to receive the PWM signal and amplify the PWM signal; a demodulator circuit configured to receive and demodulate the amplified PWM signal to obtain a demodulated audio signal, and to output the demodulated audio signal to a speaker; and a feedback circuit configured to feed back the demodulated audio signal output by the demodulator circuit, and to output a feedback signal to an input end of the modulator circuit. Here, the feedback circuit includes an analog-to-digital converter and a loop filter. The switch stage circuit includes a driver and two gallium nitride (GaN) field effect transistors (FETs).

  • Systems and methods for vehicle sound enhancement
    Patent number: 11843909
    Abstract: Embodiments are disclosed for enhancing engine sound. An example method for a vehicle comprises acquiring a signal including harmonic content generated by an engine of the vehicle, upmixing the signal into a plurality of channels for a given number of engine orders, adjusting an order filter for each engine order of the given number of engine orders based on operating conditions of the engine, filtering each channel of the plurality of channels with the corresponding order filter, mixing the filtered channels into a mono output, and outputting the mono output to at least one speaker in the vehicle. The mono output is delayed based on a position of the at least one speaker such that an occupant of the vehicle perceives the mono output as originating from the engine.

  • Methods for forming a hidden audio assembly
    Patent number: 11827162
    Abstract: Methods and systems are provided for a vehicle headliner. In one example, a method for forming the headliner includes forming a recess and an opening for a support structure in a base substrate layer of the headliner during heat treatment of the base substrate layer. The method further includes inserting the support structure in the recess and the opening and covering the base substrate layer with a skin. A positioning of the support structure within the base substrate layer allows an outline of the support structure to be undetectable through the skin by sight or touch.

  • SYSTEM AND METHOD FOR MULTI-BEAM CONSTANT BEAMWIDTH TRANSDUCER ARRAY
    Publication number: 20230379647
    Abstract: In at least one embodiment, a system for providing a multi-beam constant beamwidth transducer (CBT) array is provided. The system includes an array of transducers and at least one controller. The array of transducers generates a first sound beam in a listening environment. The at least one controller is programmed to determine a first time delay for each transducer to virtually curve the array of transducers to provide a first beamwidth for the first sound beam and to determine a second time delay for each transducer to virtually rotate the array to steer the first sound beam one of off-axis and on-axis. The at least one controller is programmed to sum the first time delay for each transducer and the second time delay for each transducer to steer the first sound beam with the first beamwidth at a first angle from the array of transducers into the listening environment.

  • Detachable mixed-source portable speakers
    Patent number: 11820295
    Abstract: Methods and systems are provided for use of a portable speaker system both as part of a vehicular audio system and as a stand-alone audio system. A speaker may be attached to an internal speaker receptacle of a vehicle and coupling to an audio amplifier of the vehicle. Audio performances received by the speaker from the audio amplifier may then be played by the speaker. The speaker may also be decoupling from the audio amplifier of the vehicle and detached from the internal speaker receptacle of the vehicle. Audio performances received by the speaker from a wireless interface coupled to the speaker may then be played by the speaker.

  • Active noise cancellation system and method with time division multiplexing
    Patent number: 11823654
    Abstract: In at least one embodiment, an active noise cancellation system. The system includes a first controller, a data bus, and a second controller. The first controller receives first information from a plurality of noise sensing devices and second information from an audio system. The first controller employs a time division multiplexing scheme to generate a multiplexed stream of data including the first information and the second information. The data bus transmits the multiplexed stream of data on a single data channel. The second controller receives the multiplexed stream of data on the single data channel and separates the first information from the second information on the multiplexed stream of data to perform ANC functionality.
