摘要： PURPOSE:To obtain an excellent required band characteristic by adhering a piezoelectric element to the inner flat face or its rear face of a non-circular recessed part being in the outer peripheral shape formed to an elastic thin plate so as to attenuate remarkably the high-order resonance level. CONSTITUTION:A metallic plate 5 forms a dish as an elastic thin plate and the recessed part 6 whose outer peripheral shape is non-circular and circular piezoelectric element thin plate 2 is adhered on a plane 7 in the recessed part 6. When the plane with a recessed part is a non-circle such as ellipse or oblong circle, the resonance frequency of the major axis and the minor axis is different. Although the difference of the resonance frequency at the major axis and the minor axis is not so much large, the high-order resonance is larger in comparison with the 1st resonance and the energy of resonance is scattered. Then the high-order resonance level is attenuated remarkably by selecting the ratio of the major and minor axes to apropriate value.

摘要： PURPOSE:To flatten sound-voltage frequency characteristics and to obtain a piezoelectric type electrical sound converter with satisfactory reproducibility by covering a sound leaking hole which is provided at a back-pressure air chamber plate by a sound-resistant material in the receiver such as a telephone set or an interphone. CONSTITUTION:A pre-air chamber 32 is formed between a metallic diaphragm 23 and a dome-like case 21 which has plural sound discharging holes 22. The metallic diaphragm 23 is bonded closely by a ceramic piezoelectric body 24 and adhesives, and an oscillator 31 is constituted by both. A back-pressure air chamber 33 is formed between the oscillator 31 and a back-pressre air chamber plate 25, and a sound leaking hole 26 and an input terminal 27 are provided at the back- pressure air chamber plate 25. a sound-resistant material 28 is stuck to the sound leaking hole 26, and suppressed by a terminal plate 29. Since the value of sound resistance and the permeability degree of the sound-resistant materiala 28 have a high correlation, a piece of woven fabric having the small planar fluctuation width of the permeability degree is selected for the sound-resistant material, and the value is set to 15-40cc/cm /sec.

摘要： PURPOSE:To attain free setting of an acoustic characteristic by providing a convex and concave on the surface of a case and regulating vibration mode of the case itself to adjust the resonance frequency of the case itself. CONSTITUTION:An electric signal from input terminals 28 and 29 acts on a piezo-electric vibrator 20 and causes the vibrator 20 to generate machine strain according to the input electric signal. The machine strain generated in the vibrator 20 propagates to a front case 23 and a rear case 26 via the support part of a metallic diaphragm 22, causing the case 23 itself to vibrate. However, the convex and concave provided on the surface of the cases 23 and 26 restrict the case vibration mode. Therefore, proper selection of degree of the convex and concave makes the control of acoustic charactetistic of a piezo-electric electroacoustic transducer possible.

摘要： PURPOSE: To detect a pressed point on a film by using a polymer piezoelectric film which is subjected to uniaxial orientation and polarization processing.
CONSTITUTION: The orienting directions of polymer piezoelectric films 1 and 2 are set rectangular to fixed parts 5 and 6 as well as adhered parts 9 and 10 respectively. A polymer film 4 is stuch to the films 1 and 2 with no malformation such as shrinkage, etc. Then these films are fixed with adhesion on a transparent substrate 3. The AC power given from an oscillator 16 is applied to an electric/mechanical converter 7. Thus the film 1 extends and contracts in its orienting direction. These vibrations form the longitudinal waves and unified at a film adhered part 9 to propagate approximately in parallel into the film 4. These waves are converted again into electric signals by pickups 8aW8h. When the film 4 is pressed with a finger, etc., the pickup output is reduced at the area near the pressed point on the film. Thus the pressed point can be detected on a film.

摘要翻译：目的：通过使用经受单轴取向和偏振处理的聚合物压电膜来检测膜上的压制点。构成：聚合物压电薄膜1和2的取向方向分别设置成固定部分5和6以及粘附部分9和10。聚合物膜4与薄膜1和2接触，没有畸变，例如收缩等。然后将这些薄膜粘附在透明基板3上。将由振荡器16给出的AC电力施加到电/机械转换器因此，胶片1在其定向方向上延伸并收缩。这些振动形成纵波，并且在膜粘附部分9处一体化，以大致平行地传播到膜4中。这些波通过拾取器8a-8h再次转换成电信号。当用手指等按压胶片4时，胶卷上的按压点附近的拾取输出减少。因此，可以在胶片上检测按压点。
