摘要： An elastic wave control element includes a piezoelectric material which is inserted into a propagation path for an elastic wave or installed in an oscillator to allow the elastic wave in a selected frequency to be damped, reflected, or transmitted. The piezoelectric material is provided with a pair of electrodes between which a negative capacitance circuit is connected to allow a loss factor of the negative capacitance circuit in a selected frequency or frequency band to be matched with a dielectric loss factor of the piezoelectric material.
摘要翻译：弹性波控制元件包括插入弹性波的传播路径中或安装在振荡器中以允许所选频率中的弹性波被衰减，反射或传输的压电材料。压电材料设置有一对电极，在该对电极之间连接有负电容电路，以使所选频率或频带中的负电容电路的损耗因数与压电材料的介电损耗因数相匹配。

摘要： A sound insulation/absorption structure, a sound insulation/absorption device, and a structure having these applied thereto and a member constituting the same, are capable of insulating or absorbing sound by stiffness control. The sound insulation/absorption structure comprises a film member, such as a polymer film or metal foil, and a frame body having at least one annular opening, the film member being fixed to the frame body, the section of the film member surrounded by the frame body being of a curved shape such as a dome, wherein the resonance frequency of the in-plane stretching of this curved shape is set at a frequency equal to or higher than the audible frequency band, so as to insulate or absorb sound by the elastic force of the film. The film member may be replaced by an acrylic, polyethylene terephthalate or other plastic plate, an aluminum or other metal plate, or a veneer or other plate member, molded into a curved shape, such as a dome, a semi-cylinder and a cone.
摘要翻译：隔音/吸收结构，隔音/吸收装置以及这些结构应用于其上的构件和构成它们的构件能够通过刚度控制来绝缘或吸收声音。隔音/吸收结构包括诸如聚合物膜或金属箔的膜构件和具有至少一个环形开口的框架体，膜构件固定到框架体，膜构件被包围的区段框架体是圆弧状的弯曲形状，其中，该弯曲形状的面内拉伸的共振频率被设定为等于或高于可听频带的频率，以便绝缘或吸收声音胶片的弹性力。膜构件可以由丙烯酸，聚对苯二甲酸乙二醇酯或其它塑料板，铝或其他金属板，或者被成型为弯曲形状的单板或其它板构件代替，例如圆顶，半圆筒和锥体。
