Abstract (en)
[origin: WO9213338A1] The invention relates to accoustic transducers of the flextensor type wherein a body having an oblong cross-section is acted upon by a motor along the long axis of such cross-section. The invention aims at using visco-elastic means (104) to absorb slow deformations of the case (401) under the immersion effect. These visco-elastic means present an important stiffness to frequencies of utilisation of the transducers so as to efficiently transmit the vibrations from the motor to the case. The invention allows to produce a flextensor transducer which may withstand an important immersion without breaking the motor and whose efficiency is higher than 75 %.
