    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： An improved audio frequency speaker comprises a speaker cone suspended for movement to generate air displacement, a voice coil having at least one winding attached to the cone and a magnet having a magnetic field. The magnet is located such that at least a portion of the coil is within the magnetic field to thereby cause the coil and the cone to move when a current from an audio frequency drive signal flows through the coil winding. At least one piezoelectric actuator is secured to the cone and is adapted to receive the audio frequency drive signal. The at least one piezoelectric actuator moves the cone, at least at higher order frequencies of the audio frequency range, to thereby enhance the performance range of the speaker at the higher order frequency so that a single speaker covers the entire audio frequency range.

    摘要： A multi-driver, coaxially mounted loud speaker array utilizing a high frequency bi-morph driving element that is totally contained within the hollow core of the voice coil former of a lower frequency loud speaker. The outwardly radiating conical edge of the high frequency device's diaphragm is annularly fixed by a compliance to the inner surface of the referenced voice coil former or to the diaphragm which radiates outwardly therefrom and is excited by the former. A significant advancement in the art is acquired by the realization of a cavity between the situs of the bi-morph driving element and the back of the former--excited diaphragm, behind the annular compliance. This feature allows a design engineer to literally tune the response of the higher frequency loud speaker by deliberately varying the volume of the cavity.
