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 device includes an acoustic-vibration member, an actuator that is driven on the basis of a sound signal and that includes a displacement-output unit that can obtain the displacement corresponding to the sound signal, and a displacement-output-transfer member configured to connect the displacement-output unit to a point predetermined on a face of the acoustic-vibration member. A displacement output of the actuator is transferred to the predetermined point via the displacement-output-transfer member, and the acoustic-vibration member is excited in a face direction from the predetermined point according to the displacement output.
