Piezoelectric ultrasonic trance due sir which possesses, the internal electrode for bandwidth promotion and mode control

摘要

One for ultrasonic trance due sir, the bandwidth which is expanded and/or the device which transmits the ultrasonic energy which possesses supuriusumodo which is controlled is disclosed. In one execution example, the ultrasonic picture conversion system, has the system chassis and the plural stacks which generate the ultrasonic signal and the trance due sir assembly which is connected to the system chassis which possesses the plural stacks which are formed from the intermediate electrode of one or more where each one is inserted between piezoelectric layer and, has possessed. This assembly furthermore has the 1st electrode which is arranged on the 1st end of each stack, the 2nd electrode in the 2nd end of opposite side is arranged on, the 1st electrode and the 2nd electrode is connected by the system chassis of the ultrasonic picture conversion system, the intermediate electrode the 1st electrode or is connected to the 2nd electrode.
