Abstract: PURPOSE:To eliminate the generation of high tension charge along with focal electric effect and piezoelectric effect, and prevent spark discharge from being generated and prevent a power device from being damaged, by connecting the resistance unit of a specified value in parallel with and between the electrodes of piezoelectric elements. CONSTITUTION:When AC voltage is applied to piezoelectric elements 1, 2, then longitudinal oscillation is generated, and at the disc section 5' of a twist coupling element 5, curvature oscillation with the fulcrum of a bolt 6 is excited. As a result, on the rectangular beam section 5'' of the twist coupling element 5, elliptic oscillation is generated, and via a frictional force, rotational torque is applied to a rotor 7. In order to discharge an electric charge due to the focal electric effect of the piezoelectric elements 1, 2 which is generated by difference between temperatures under operation and under rest, the resistance unit 11 of a value higher sufficiently than the working impedance of a motor and with discharge time-constant lower sufficiently then thermal time-constant is connected in parallel with and between terminal sheets 1', 2'.

Filed: 1989-03-14
Abstract: PURPOSE:To obtain a strong sound pressure for a sound wave only in a special direction from a speaker by providing plural sound absorbing panels in front of at least one speaker close to the speaker and acoustic panels whose plate face is arranged at a prescribed interval in the radiation direction. CONSTITUTION:A component in a reference axis direction (in this figure, a radiation axis and a center axis of a speaker are coincident) of a sound wave radiating from the front face of a speaker 1 accommodated in a cabinet 4 passes through a gap of a sound absorbing panel 5 and reaches a listening point as shown in the arrow A. On the other hand, in the directions of the arrows B, C obliquely deviated from the reference axis, the sound wave is in touch with the panel 5 and a transmission loss is caused due to its sound absorbing property in the case of transmission and the sound pressure is attenuated. In this case, the direction of the arrow C is absorbed more the number of times than the direction of the arrow B by the sound absorbing panel 5, then the attenuation is increased. An optimum value exists for a sound absorbing panel 5 shown in figure with interval (d), length L and width B depending on the absorbed frequency band and the interval (d) is selected as 3-7 times with respect to the thickness (t) of the sound absorbing panel 5.
