摘要: Electro-active actuators (310) and methods of manufacturing such actuators are described with such actuators (310) having a plurality of electro-active segments (311) arranged along a curved line with each segment (311) being essentially planar and coupled to adjacent segments (311) through joint sections (312) placed at opposite corners of the segment (311). The actuators (310) exhibit a displacement in a different direction than the direction of displacement of a segment when seen in isolation. They can be made from a continuous tape of material, preferably by die punching.

摘要: A piezoelectric device comprising a continuous piezoelectric element (10) extending alternately back and forth to form a plurality of parallel, straight portions (14) arranged in a stack with intermediate linkage portions (15) at alternate ends of the straight portions (14). Each straight portion (14) is constructed and arranged with electrodes (12, 13) to bend, on activation, in the stacking direction in which the straight portions (14) are stacked with opposite curvature in two halves (16, 17) of the straight portion (14) to create displacement between the ends of the straight portion (14) in the stacking direction adding in series through the stack. The continuous nature of the piezoelectric element (10) eases manufacture. Devices with two types of construction are disclosed. Firstly, the continuous piezoelectric element (10) may have a bender construction such as a bimorph bender construction. Secondly, the continuous piezoelectric element (101) may be a sheet of piezoelectric material having overlapping slits (102) extending from alternate sides to form the straight portions (103) between the slits (102), with opposed electrodes (105) arranged on each major surface of the sheet in pairs separated across, and extending along, the straight portions (103).

摘要: A loudspeaker comprising: a support, a sound-generating element mounted to the support for vibration to generate sound; and an electro-active device coupled between the support and the sound-generating element for vibrating the sound-generating element in response to an electrical signal. The electro-active device comprises a structure extending along a minor axis which extends in a curve around a major axis parallel to the vibration direction of the sound-generating element, the structure comprising successive electro-active portions arranged with electrodes to bend around the minor axis on activation in response to application of the electrical signal to the electrodes, and coupled together such that bending of successive portions causes concomitant rotation of adjacent portions around the minor axis adding incrementally along the minor axis, which rotation causes concomitant change of the axial length of the structure along the major axis.

摘要: An equivalent to the spatial separation either side of a nominal median plane that is inherent in a bimorph (with one piezoelectric layer on one side, and the second on the other side of the plane) is attained by structurally shaping the cross-section of a simple, single piezoelectric layer (11) such that it has a multiplicity of piezoelectric portions arranged in two generally-planar groups one either side of a median plane, so that any dimension change undergone by a portion on one side of that plane will tend to bend the whole device in the opposite direction to the same sense dimension change undergone by a portion on the other side of that plane. The simple, single layer acts as though it were a bimorph if elongate and beam-like, bending along its length, one end moving up/down, or back/forth, relative to the other but with any need for an internal, electrode.
