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 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： 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.

摘要： A loudspeaker comprises the casing (22) of a portable electronic device, having mounted thereon a sound generating element (21) which may be a transparent cover for a display. The sound generating element (21) is driven to generate sound by a piezoelectric actuator (1) extending along a sector of a circle and coupled at one end (7) to the casing (22) by a first block (24) and at the other end (8) to the edge (26) of the sound generating element (21) by a second block (25). The first block (24) and the second block (25) each have stop surfaces spaced apart from each other and capable of engaging each other to limit the amount of relative movement of the ends (7) and (8) of the actuator (1) to prevent damage to the actuator (1). The sound generating element (21), the first and second blocks (24) and (25) and the actuator (1) form an assembly which may be manufactured for subsequent assembly to the casing (22).

摘要： A loudspeaker comprises a sound generating element mounted on a support structure, and two rotary actuators I mounted at opposing edges of the sound generating element. The actuators are operable to drive motion of the sound generating element relative to the support structure including a component of rotation. The loudspeaker produces a greater sound output than if driven at one edge only, and is particularly suitable for use in a portable electronic device such as a mobile telephone, in which case the support structure may be a portion of the casing of the, device and the sound generating element maybe a transparent panel covering a display device.

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.
