摘要： A vibration actuator that is capable of bringing a vibration body into pressure contact with a driven body stably during long time while reducing obstruction of excitation of vibration in the vibration body by the pressure force. The driven body is in contact with the vibration body by pressure force given by a pressing member. A vibration isolation member is arranged between the vibration body and the pressing member. The vibration body and the driven body move relatively by vibrations in first and second vibration modes that are excited in the vibration body by applying alternating voltage to a piezoelectric device on the vibration body. Face pressure that acts to the piezoelectric device by the pressure force from the pressing member in first and second areas that respectively include nodal lines in the first and second vibration modes and their vicinities is higher than that in the other area.

摘要： Piezoelectric Micromachined Ultrasound Transducer (pMUT) arrays for ultrasonic imaging, and related apparatuses, systems, and methods are disclosed. In one embodiment, an ultrasonic imaging assembly comprises a substrate and a plurality of array elements arranged on the substrate in an array. Each array element comprises at least one pMUT disposed on the substrate each having a geometry configured to accept a predetermined fundamental mode vibration. The plurality of array elements are configured to transmit and receive at least one ultrasound beam based on the predetermined fundamental mode vibration. By sizing the pMUTs to correspond to a desired fundamental mode vibration, the pMUT array has improved sensitivity, and can be produced relatively cheaply compared to conventional dicing methods.

摘要： The invention relates to a piezoelectric transducer particularly for use in transit time measurements. The object of the invention is to provide a piezoelectric transducer which ensures an in-phase two-dimensional pulse emission which, independent of the selection of a definite excitation frequency, substantially closely follows the electric excitation at a low time deformation of the pulse owing to transient and dying-out operations and which permits to obtain sufficiently high sound levels at low amplitudes of the excitation voltage. These objects are realized according to the invention in that the center of mass of the entire transducer system is remote from a sound emitting and sound receiving, respectively, surface (4) and in that at least one piezoelectric sheet (1) is provided which via one of its narrow sides (21) is connected to at least one rigid, geometrically and variably adaptable cover plate (3) of low mass, compared to the entire transducer and sheet mass, respectively, in such a manner that the entire surface (4) of the cover plate (3), at least in the sound emitting mode, is substantially and completely covered by the surface lines (5) of an emission angle (.alpha.) under which the piezoelectric sheet irradiates said cover plate (3), and only to said surface (4) the function of being a sound emitting and/or a sound receiving area is assigned.
