  • Headphone amplifier circuit for headphone driver, operation method thereof, and USB interfaced headphone device using the same
    Patent number: 10149081
    Abstract: Provided herein are a headphone amplifier circuit for a headphone driver, an operation method thereof, and a universal serial bus (USB) interfaced headphone device using the same. The output stage of the headphone amplifier circuit is improved to have a differential output structure so as to effectively solve the crosstalk issue and increase the isolation between the left and the right channels such that the audio content presents a spatial perception and a distance perception more specifically.
    Type: Grant
