Title: Method for adjusting frequency characteristic of piezoelectric transducer
Inventor: KOBAYASHI TERUO
IPC: H04R1/22
Filed: 1985-04-24
Abstract: PURPOSE:To suppress the extension of distribution of acoustic characteristics to reduce the cost and to improve the yield even if parts of general precision are used, by providing a minute hole on a back air chamber plate which forms a back air chamber between this plate itself and a piezoelectric oscillator and changing the diameter or/and the length of this minute hole. CONSTITUTION:The capacity of the back air chamber and a small hole of the back air chamber plate are designed newly, and an acoustic resistance material is disused, and the diameter and the length of the small hole are adjusted. A back air chamber plate 5 is provided with a minute hole 7 and does not use the acoustic resistance material. Though the diameter and the length of the minute hole 7 are designed with the center value of distribution of the resonance frequency of a piezoelectric oscillator 4, the flatness of the frequency characteristic is lost if the resonance frequency is high. In case of production without adjusting, the acoustic pressure level rises greatly near A2kHz. If this frequency characteristic is shown, the diameter of the minute hole 7 is increased as shown by a broken line in the figure to make the frequency characteristic flat as shown by a broken line B.

Filed: 1983-05-19
Abstract: PURPOSE:To enable to smoothly slide and deliver the titled device without setting the angle of inclination of a shoot rail at a steep angle by forming three or mor projections on the back surface of a resin sealed case. CONSTITUTION:Three or more projections 22a-22c e.g. of semisphere are formed on the back surface 21a of the resin sealed case 21. When said device thus constructed is carried by means of the T-shaped shoot rail 14, only the projections 22a-22c come into contact, and accordingly the coefficient of friction between said case 21 and the shoot rail 14 largely decreases. Therefore, it becomes possible to smoothly slide and carry said device without the necessity to set the angle of inclination of the shoot rail at a steep angle, and the heat dissipating efficiency of this semiconductor device itself can be improved.
