Title: Jonghwa Won: Innovator in Audio Technology
Introduction
Jonghwa Won is a notable inventor based in Yongin-si, South Korea. He has made significant contributions to the field of audio technology, holding 2 patents that showcase his innovative approach to electronic devices.
Latest Patents
His latest patents include an audio device and an operating method for the audio device. The audio device features a jack slot that is detachably connectable with an audio jack. It incorporates a detection and monitor unit that constantly supplies a first and second voltage to the jack slot. This unit detects whether a conductive material is attached to the jack slot based on changes in the voltages during a first detection mode. Additionally, a determination unit assesses whether the conductive material is the audio jack based on voltage changes. If the conductive material is not the audio jack, the detection and monitor unit switches to a second detection mode, monitoring voltage changes while periodically supplying the voltages.
Another patent involves an electronic circuit designed to perform gain control and gain compression to enhance the characteristics of analog output. This circuit includes a peak detector, a gain controller, and a compressor. The peak detector identifies the peak level from a digital input, while the gain controller outputs a digital gain aimed at increasing the peak level to a target level. The compressor provides the gain controller with a compressed gain based on the detected peak level. During a compression interval, where the peak level exceeds a threshold, the output digital gain increases as the peak level decreases.
