| description | PURPOSE:To obtain a miniaturized, lightweight wave transmitter and receiver with excellent cahracteristics by providing a miniaturized electroacoustic transducing part for wave reception made of a piezoelectric or electrostrictive material in contacting with the acoustic-wave radiation surface of an electroacoustic transducing part for wave transmission. CONSTITUTION:The Langevin type oscillator consisting of a front mass 1, electrostrictive material 2, and rear mass 3 has volume aout 10 as large as the element for wave reception for the purpose of wave transmission. During the wave transmission, a signal is transmitted from the front mass 1. The electrostrictive material 4 for wave reception is supported on its rear surface side by something like a hard complete steel body and receives sound pressure efficiently. The wave transmission and reception are performed by the different elements to hold high the both efficiencies. Further, their structures are put together in one body to reduce the entire size. |
