Title: Innovations of Leyi Yin in Audio Technology
Introduction
Leyi Yin is a prominent inventor based in Austin, TX, known for his significant contributions to audio technology. With a total of nine patents to his name, he has made remarkable advancements in the field of audio amplification and processing. His work focuses on enhancing audio quality and performance through innovative engineering solutions.
Latest Patents
Among Leyi Yin's latest patents is a system for equalization in a multi-path audio amplifier designed to cancel variations due to multi-path output impedance differences. This multi-path audio amplification system provides an output drive signal to electromechanical output transducers, resulting in improved undistorted headroom, reduced path switching noise, and enhanced frequency response performance. The system features multiple signal amplification paths that receive an audio input signal, each with differing output impedances. A mode selector is employed to choose an active amplification path to supply the output drive signal. Additionally, at least one of the signal amplification paths includes an equalization filter to compensate for phase or gain differences caused by the interaction between the differing output impedances and the impedance of the electromechanical transducer.
Another notable patent focuses on low-latency audio output with variable group delay. This system includes a digital delta-sigma modulator that quantizes a digital audio input signal into a quantized signal. A filter then processes this quantized signal to generate a filtered quantized signal, which features a variable group delay. Finally, a current-mode digital-to-analog converter converts the filtered quantized signal into an equivalent current-mode analog audio signal.
