Low frequency oscillator, the omni-directional type low frequency underwater acoustic transducer using the same and the cylindrical radiation type low frequency underwater acoustic transducer using the same |
摘要 |
A low frequency oscillator includes a plurality of drum-shaped oscillators. Each of the drum-shaped oscillators is constructed so that a pair of disk-shaped flexural vibrators is attached on both open ends of a conductive cylinder so as to be arranged face to face. And a conductive elongated coupling member is fixed to adjacent the drum-shaped oscillators at a central portion thereof so as to electrically connect between adjacent the disk-shaped flexural vibrators and thereby coupling the drum-shaped oscillators along a central axis thereof.
