ACOUSTIC TRANSDUCER COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide a waveguide supporting mechanism and a damping mechanism which are easily manufactured and assembled. SOLUTION: A waveguide suspension 2 and a module-type mechanism to an acoustic waveguide 4 have a damping element 6 to be used with the waveguide 4 for generating torsional strain waves or longitudinal strain waves by transmitting current pulses. The damping element 6 is used for preventing the reflection of acoustic strain waves and has both a sleeve 27 for surrounding the waveguide and a mechanism 29 for adding pressure to the sleeve 27. The sleeve 27 prevents the reflection of acoustic strain waves by adding pressure to the waveguide 4 and gradually damping the energy of the acoustic strain waves along the length of the waveguide 4 surrounded by the sleeve 27 of the damping element. A return conductor 1 is positioned by a response of a measuring system to suppress ringing of signals received from a pickup coil 13 to a minimum. COPYRIGHT: (C)2006,JPO&NCIPI
