Title: Hsu-Ching Liao: Innovator in Electret Loudspeaker Technology
Introduction
Hsu-Ching Liao is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of electret loudspeaker technology, holding two patents that showcase his innovative approach to sound devices. His work is primarily associated with National Taiwan University, where he continues to advance research in this area.
Latest Patents
Hsu-Ching Liao's latest patents focus on the development of electret loudspeaker devices. The first patent describes an electret loudspeaker device that includes a diaphragm, a first perforated electrode, and a first spacer. This device features a diaphragm composed of a first electret, a second electret, a polymer layer, and an electrode layer. Notably, at least one layer of the first or second electret is formed from expanded polytetrafluoroethylene. The second electret is positioned on one side of the first electret, while the electrode layer is on the opposite side. The polymer layer, made from a hydrophobic material, is placed on the second electret. The first perforated electrode is situated close to the polymer layer, supported by the first spacer, which defines a first chamber.
The second patent also pertains to an electret loudspeaker device, which includes a diaphragm with an electret layer and an electrode layer. In this design, the first perforated electrode is stacked on a side of the diaphragm near the electret layer and features multiple holes. The first spacer is positioned between the diaphragm and the first perforated electrode, containing a first distribution area and several second distribution areas. The first distribution area has openings that penetrate through the spacer, each with a specific volume between the diaphragm and the first perforated electrode. The second distribution areas also have openings, with a notable difference in volume between the first and second openings being greater than 10%.
