摘要： A hybrid actuator (100A) includes a magnetostrictive actuator (110) having a magnetostrictive element (111), and a moving-coil actuator (130) including a movable portion (132) having an outer periphery to which voice coils (131a), (131b) are attached. The actuator (110) is fixed to the movable portion (132) of the actuator (130) so that the direction of displacement output of a drive rod (113) becomes the same as the displacement direction of this movable portion. Since the actuator (110) is fixed to the movable portion (132) of the actuator (130), together with a displacement output in response to a high-frequency-range audio signal, which is obtained by the actuator (110), a displacement output in response to a low-frequency-range audio signal, which is obtained by the actuator (130), is also obtained at a tip of the drive rod (113). By abutting the tip of the drive rod (113) against an acoustic diaphragm, a wide band audio output can be obtained.

摘要： A speaker has a pipe member with opposed open ends, and a sounding body that is attached to any one of the opposed open ends of the pipe member on the same axle as that of the pipe member. The sounding body is driven on the basis of an acoustic signal that is applied to the sounding body. Sound wave radiated from the sounding body and passed through an inside of the pipe member vibrates with a pipe wall of the pipe member, thereby to enable sound wave corresponding to the acoustic signal to radiate from a whole of an outside surface of the pipe member to outside.

摘要： A speaker apparatus which can remove undesirable vibrations and can produce sounds of excellent quality of acoustic signals having high audio frequencies is presented by increasing a strength of a flat joint portion and by properly setting a mass ratio between a central dome-like diaphragm and an edge-like diaphragm of a speaker diaphragm. This speaker apparatus includes a diaphragm portion in which a mass ratio of the edge-like diaphragm relative to the dome-like diaphragm falls within a predetermined range near 1 and a fixed portion at which a bobbin of a voice coil or an end face of a conductive one turn ring is bonded to and fixed to a flat portion for joining the dome-like diaphragm and the edge-like diaphragm so that mechanical strength of a joint flat portion of the diaphragms can be increased.

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： In a lever-arm displacement-increasing device, two lever arms are joined at one end. The other end of one of the lever arms is connected to a fixed portion that supports the rear end of an actuator element, and the other end of the other lever arm is connected to a rigid connecting portion connected to the front end of the actuator element. The displacement force of the actuator element is transmitted to the lever arms through the connecting portion, and is further transmitted to a joint between the lever arms. The joint functions as an output displacing portion. The joint changes the displacing direction of the actuator element to a direction orthogonal thereto, and produces a displacement larger than the displacement of the actuator element.
