Introduction

Sebastian Mingjie Chang is an accomplished inventor based in Canberra, Australia. He has made significant contributions to the field of audio technology, particularly in the development of transducer apparatuses that enhance sound quality in noisy environments. With two patents to his name, Chang's work demonstrates a commitment to innovation and problem-solving in audio sensing.

Latest Patents

Chang's latest patents include a transducer apparatus designed for positioning and high signal-to-noise-ratio microphones. This invention relates to a device that captures high-quality audio signals, including speech, even in challenging acoustic environments. The apparatus utilizes a non-acoustic transducer or sensor that is adapted in two ways: first, it senses free-field acoustical sounds with directive sensitivity; second, it detects vibrations or movements on the user's skin that arise from their voice. The combination of these adaptations allows for improved audio capture, resembling the characteristics of a close-talking microphone.

Another notable patent by Chang focuses on a transducer apparatus that provides audio sensing with high noise immunity. This invention replaces traditional acoustic microphones with non-acoustic sensors that detect vibrations or movements related to the user's voice. The non-acoustic sensors, which may include accelerometers, shock sensors, gyroscopes, and vibration microphones, enhance the device's ability to function effectively in acoustically noisy environments. Various adaptations and embodiments of this invention aim to improve the polar directivity of the sensors and explore the application of multiple non-acoustic sensors alongside acoustic microphones.
