摘要： A pressure reducer includes a piston slidably accommodated in a cylinder to define a decompression chamber and a pressure adjusting chamber. A seal member includes an elastic member and a sliding portion. The sliding portion is pressed by the elastic member such that the sliding portion slides on an inner circumferential surface of the cylinder. An annular member is located on an outer circumferential surface of the piston and between the seal member and the pressure adjusting surface. The annular member is pressed against the inner circumferential surface of the cylinder with a force that is less than a force with which the sliding portion is pressed against the inner circumferential surface of the cylinder. Thus, the pressure reducer prevents the piston from being moved by an excessive amount with highly accurately adjusting pressure.

摘要： An acoustic resistor placed at a tone aperture portion of an electroacoustic transducer is made of a mesh, a part of which is filled with a filler to create an acoustically opaque portion at which the acoustic resistor is secured to the tone aperture portion of the transducer. The acoustic impedance of the resistor is independent of whether it is secured to the transducer, since the non-filled part of the mesh is not altered when the resistor is attached to the transducer. The invention further makes it possible to obtain an acoustic impedance at the tone aperture portion which is independent of the accuracy in dimensions of the tone aperture by making an acoustic resistor in such a manner that the portion other than the acoustically opaque portion may be located within the tone aperture area.
摘要翻译：放置在电声换能器的色调孔部分处的声电阻器由网状物制成，其中一部分填充有填充物，以产生声学不透明部分，声学电阻器固定在换能器的色调孔部分处。电阻器的声阻抗与其是否固定在换能器无关，因为当电阻器连接到换能器上时，网格的未填充部分不会改变。本发明还可以通过制造声阻抗器来获得音调孔部分处的声阻抗，该声阻抗与音腔的尺寸精度无关，使得声透镜部分之外的部分可以位于音孔区域。
