Dsr speaker elements and methods of manufacturing thereof

There is provided a dsr speaker comprising at least a central moving element, a plurality of peripheral flexure benders, each flexure bender comprising at least a pair of electrodes and at least a piezoelectric material layer, the flexure benders being connected to said moving element and being configured to move said moving element along an axis perpendicular to a moving element surface, in response to an electrical stimulus applied to said electrodes, in order to produce sound, and at least a mechanical stopper which is configured to limit the motion of said moving element. Various manufacturing methods are also described.. ... Audio Pixels Ltd

Microelectromechanical apparatus for generating a physical effect

A microelectromechanical apparatus for generating a physical effect, including an array of moving elements, each coupled to a mechanical support by at least one flexure which is associated with at least one piezoelectric member which is operable to be strained by an electrical field applied to the piezoelectric member, thereby flexing the flexure to which the piezoelectric member is coupled; an electrical wiring, including a group of electrodes, wherein each electrode out of the group of electrodes is coupled to at least one of the piezoelectric members; wherein the electrical wiring is operable to concurrently transfer different sequences of electric fields to different piezoelectric members, thereby controllably inducing movement of moving elements of the array for creating the physical effect; and a motion restriction mechanism for maintaining a maximal motion distance for each of the moving elements when actuated via the corresponding flexure and piezoelectric member.. . ... Audio Pixels Ltd

Apparatus and methods for individual addressing and noise reduction in actuator arrays

Apparatus for generating a target physical effect, at least one attribute of which corresponds to at least one characteristic of a digital input signal sampled periodically, the apparatus comprising a multiplicity of electrostatic actuator elements, each comprising a moving element moving between first and second electrodes, the multiplicity of electrostatic actuator elements including nr first subsets (r-subsets) of actuator elements and nc second subsets (c-subsets) of actuator elements, wherein a first partitioning of the multiplicity of actuator elements yields the nr first subsets (r-subsets) and a second partitioning of the multiplicity of actuator elements yields the nc second subsets (c-subsets); a first plurality of nr electrical connections (r-wires) interconnecting the moving elements of actuator elements in each r-subset, such that the moving element of any actuator element in each individual r-subset is electrically connected to the moving elements of all other actuator elements in the individual r-subset, and electrically isolated from the moving elements of all actuator elements not in the individual r-subset; a second plurality of nc electrical connections (a-wires) interconnecting the first electrodes of actuator elements in each c-subset, such that the first electrode of any actuator element in each individual c-subset is electrically connected to the first electrode of all other actuator elements in the individual c-subset, and electrically isolated from all actuator elements not in the individual c-subset; a third plurality of nc electrical connections (b-wires) interconnecting the second electrodes of actuator elements in each c-subset, such that the second electrode of any actuator element in each individual c-subset is electrically connected to the second electrode of all other actuator elements in the individual c-subset, and electrically isolated from all actuator elements not in the individual c-subset; and a controller electrically.. . ...
