摘要： An electroacoustic transducer has an cup chamber and a diaphragm made of deformable electrostrictive polymer, which is attached to an opening of the chamber. The electroacoustic transducer also has first and second adaptive electrode layers formed on a front surface and a rear surface of the diaphragm, across which audio signal voltage biased by a direct-current biased voltage is applied. The first and second adaptive electrode layers have shapes that are adjustable according to a change in a shape of the diaphragm. The diaphragm is formed to make maximum a difference in air pressure of the front surface and the rear surface of the diaphragm, thereby forming any one of concave and convex shapes thereof.

摘要： A loudspeaker includes a flat plate diaphragm mounted in a speaker frame and which is driven by a plurality of magnetic drivers each having a magnetic gap, a voice coil bobbin connected to the diaphragm at a respective node portion of the divided vibration mode and a voice coil in the respective magnetic gap and being wound around the voice coil bobbin therein. Rotational vibration of the diaphragm is prevented by a pole member which is connected from the center of the diaphragm to a damper supported behind the speaker frame on a damper supporting frame. The leverage due to the longer length of the pole member makes the damper member more effective in resisting rotational vibration. The damper supporting frame is mechanically connected to the speaker frame and/or magnetic drivers to add stiffness to the structure.

摘要： A diaphragm for a loudspeaker includes first and second sheet members between which a core member is sandwiched and secured so that the core member has peripheral edge portions extending between the edges of the sheet members and at which the core member is of relatively low strength. A strip-like edging member, preferably of a thermosetting resin, is secured to the peripheral edge portions of the core member and to the edges of the sheet members for increasing the rigidity of the diaphragm at its periphery and preventing unwanted vibrations thereat. A damper member may be secured to the diaphragm adjacent the edging member for movably securing the diaphragm to a loudspeaker frame.

摘要： A vibration sensor includes a substrate (7), a plate-like diaphragm (3) forming a capacitor, and holding assembly (2), (4), (6) for holding the diaphragm so as to be movable in parallel to the substrate. The diaphragm includes a plurality of flexible displacement portions (3c), (3d) for enabling the supporting portion of the diaphragm to be movable in parallel to the substrate. When vibrations are applied to the vibration sensor, the diaphragm portion of the diaphragm is vibrated and electrostatic capacity formed between the substrate and the diaphragm is changed based on the vibrations. Vibrations are detected on the basis of the change of electrostatic capacity. Since the vibration sensor includes the flexible displacement portions, the diaphragm becomes difficult to be vibrated due to a sound pressure and a vibration detected output can be prevented from being disturbed by the sound pressure.
