Abstract
A longitudinal vibrator assembly comprising at least one piezoceramic, magnetostrictive or electrostrictive transducer (130) having a coaxial housing (200a, 200b or 200c) comprised of at least one slotted or complete cylindrical flexural member vibrating in a circumferential or radial direction and excited by a solid state transduction material.
Claims14
An underwater Tonpilz or piston assembly operative in a first longitudinal vibrational mode comprising:
- an active housing operative for radiating sound at a substantially different frequency from the longitudinal vibrational mode.
A longitudinal vibrator assembly comprising at least one piezoceramic, magnetostrictive or electrostrictive transducer having a coaxial housing comprised of at least one slotted or complete cylindrical flexural member vibrating in a circumferential or radial direction and excited by a solid state transduction material.
A transducer device comprising a Tonpilz element having a vibrating housing actuated by ceramic, magnetostrictive alloy or electrostrictive means, said housing having a flexural or circumferential or radial mode for increasing the effective bandwidth of the device.
