发明人： DOWNS, Edward, F., Jr. , PRESTON, Dean, C.
IPC分类号： H04R25/00
CPC分类号： H04R1/083 , H04R1/1008 , H04R1/1083 , H04R5/0335 , H04R17/005 , H04R2460/13
摘要： Directional piezoelectric devices (10) and methods for their manufacture are provided that improve the quality of piezoelectric device mediated signal detection and provide new thermal imaging devices. The devices can provide over an order of magnitude improved signal to noise ratio compared with previously known devices. The devices (10) may be used along with new head mounted acoustic technologies for improved voice communication systems in inherently noisy environments. The head mounted technologies utilize microphones that are activated by pressure wherein the applied trigger pressure further serves to improve efficiency of the microphones. Also provided are head pieces that include both microphones and speakers that are particularly useful for harsh environments such as those encountered by fire fighters. The head pieces are capable of further functions related to contact with the head of the user, such as reporting physiological variables of the user, along with oral communications.
