Symbols. Cs, capacitance. d, piezoelectric charge constant (C / N). E0, permittivity of free space ( x farad / m). fr, resonance frequency ( minimum impedance frequency) (Hz).
F, force. g, piezoelectric voltage constant ( Vm / N). h, height (thickness) of ceramic element (m). ID, inside diameter of ceramic element (m). Langevin ultrasonic transducer. This ultrasonic transducer, the piezoelectric element in between the metal block is nipped, is the ultrasonic vibrator of integral structure. Since it was invented by P. Langevin (France), it has been called a Langevin type vibrator. Many of these, by tightening a ring-shaped piezoelectric.

30 Sep Introduction. The sandwiched piezoelectric ultrasonic transducer vibrating in longitudinal mode is also called the Langevin composite transducer. It consists of metal front and back masses, piezoelectric ceramic stack, metal electrodes and the prestressed bolt.
Based on the conventional design theory about.
Description:In the phase diagram, the experimental points of Table 1 are plotted. The raw material of the transparent piezoelectric transducer is obtained by the manufacturing process as thus far described. The voltage V at the source is directly proportional to the applied force, pressure, or strain. In such microelectronic devices, the miniaturization and the integration are required, while decorative factors are also involved, so that the utilization of transparent transducers which do not spoil the display effect when used in display portions has been attempted.
