Publication number: 20120230524Abstract: A piezoelectric panel speaker has a frame, piezoelectric actuators and a vibrating diaphragm set into the hollow assembly space of the frame. Two corresponding sides of the diaphragm are fixed onto the actuator, and the other two corresponding sides are spaced with said frame. The actuator is fixed onto both sides of the diaphragm, high sound pressure is generated by the diaphragm through high deformation of the piezoelectric bimorph plates. The plates of the actuator could be driven independently by the driving voltage. This could reduce the resonance of the diaphragm through the phase of driving voltage. The diaphragm could generate smooth acoustic response. Two corresponding sides of the diaphragm spaced with said frame are linked to said frame via a flexible connector. This could reduce the clamping effect of the frame against the diaphragm, and avoid the reduction of sound pressure arising from amplitude limitation of the vibrating diaphragm.Type: ApplicationFiled: March 7, 2011Publication date: September 13, 2012Applicant: HO HSIN PROGRESSIVE TECHNOLOGY CO., LTD.Inventors: Yi-Shun CHANG, Syh-Yuh CHENG

Publication number: 20090235754Abstract: An encapsulation composition for pressure signal transmission including a flexible and low modulus epoxy resin as a substance in combination with plastic balls with pressure signal transmission properties as filler is provided. Therefore, the pressure signal is transmitted by utilizing the property of easy deformation of the flexible epoxy resin under pressure. And the effect of signal transmission is enhanced by the contact between plastic balls. The encapsulation composition is used in a sensor for transmitting pressure signals. The encapsulation composition is hydrophobic, so an electronic device of the sensor can be protected against moisture or water to extend its lifetime. Compared with traditional sensors using liquid for transmitting pressure signal, this sensor using solid encapsulation composition has advantages such as easy production and processing.Type: ApplicationFiled: June 3, 2009Publication date: September 24, 2009Applicant: Industrial Technology Research InstituteInventors: Feng-Po Tseng, Kuo-Chan Chiou, Tzong-Ming Lee, Syh-Yuh Cheng, Chih-Wei Hsu
