    • PROBLEM TO BE SOLVED: To increase a harmonic component, and at the same time, attenuates a fundamental wave component when transmitting/receiving the harmonic wave using a multilayer piezoelectric body.SOLUTION: When transceiving a third harmonic wave using the three-layer piezoelectric body, the three layers are not laminated arranging a polarization direction of the three layers in order, while letting a direction of a part be inverse direction, and electrode wiring is devised. As a concrete target, electrodes of separated sides of the adjoining piezoelectric bodies are connected each other, and respectively connected to two terminals. When making a direction of residual polarity of the piezoelectric body 1 (+P) as a reference, if the piezoelectric body 2 is of the same direction (+P), and the piezoelectric body 3 is of the inverse direction in parallel (-P), sensitivity is negated for λ/4 resonance, and enhanced for 3λ/4 resonance in an electric displacement between terminals. In the way, it is possible to suppress the fundamental wave, and extract the third harmonic waves without using a filter or an amplifier.
    • 要解决的问题:为了增加谐波分量,并且同时在使用多层压电体发送/接收谐波时衰减基波分量。解决方案:当使用三层压电体收发三次谐波时 三层不是按顺序排列三层的偏振方向,而是使一部分的方向为反方向,并设计电极布线。 作为具体目标,相邻的压电体的分离侧的电极彼此连接,并且分别连接到两个端子。 当以压电体1(+ P)的残留极性方向作为参考时,如果压电体2具有相同的方向(+ P),并且压电体3的平行反方向(-P ),对于λ/ 4谐振,灵敏度被否定,并且在端子之间的电位移中的3λ/ 4谐振增强。 这样,可以抑制基波,并且不使用滤波器或放大器来提取三次谐波。
