ABSTRACT:
Wide pass band elastic wave omnidirectional transducer.
It comprises a magnetostrictive material membrane (34, 36) provided with two electrical connections at two diametrically opposite points. The potential difference between these connections is proportional to the elastic wave transmitted or received by said membrane. A continuous polarization means of the magnetostrictive membrane is also provided. It comprises a high magnetic permeability part (40, 42), whose shape substantially corresponds to that of the membrane and which is placed in the vicinity of the latter, and a permanent magnet (38) in contact with said part.
Application to the transmission of high frequency elastic waves in water (hydrophone) and to high fidelity sound reproduction in air.
