摘要： A piezoelectric speaker driving system includes a band splitter, a plurality of gain producers, an adder, a piezoelectric speaker, a sound compensator and a gain-adjusting device. The band splitter receives a first audio signal and splits the first audio signal into band signals. The gain producers gain the band signals respectively. The adder receives the gained band signals to generate a second audio signal. The piezoelectric speaker outputs a sound according to the second audio signal. The sound compensator analyzes a sound pressure level of the sound to generate a control signal. The gain-adjusting device adjusts the gains of the gain producers according to the control signal.

摘要： Methods are disclosed for separating beads and cells from a host fluid. The method includes flowing a mixture containing the host fluid, the beads, and the cells through an acoustophoretic device having an ultrasonic transducer including a piezoelectric material driven by a drive signal to create a multi-dimensional acoustic standing wave. A drive signal is sent to drive the at least one ultrasonic transducer to create the multi-dimensional acoustic standing wave. A recirculating fluid stream having a tangential flow path is located substantially tangential to the standing wave and separated therefrom by an interface region. A portion of the cells pass through the standing wave, and the beads are held back from the standing wave in the recirculating fluid stream at the interface region. Also disclosed is an acoustophoretic device having a coolant inlet adapted to permit the ingress of a cooling fluid into the device for cooling the transducer.

摘要： An ultrasonic transducer with housing contains a transducer assembly, an outer housing surface being fixed against a barrier surface for transferring ultrasonic waves to and from a barrier. The housing has an inner surface with plateau. A cap closes the housing and the transducer assembly has a piezoelectric transducer with a pressure surface around its outer perimeter and an opposite vibration surface engaging the plateau. A ring engages the pressure surface for biasing the vibration surface against the plateau. A holder engages the cap, transducer and ring for positioning and a plurality of springs are spaced around the transducer perimeter and between the cap and ring for biasing the vibration surface toward or against the raised plateau. A viscous couplant is between the vibration surface and plateau for enhancing transmission of the ultrasonic waves.

摘要： An ultrasonic generator that includes an ultrasonic generating element and a first acoustic path. The ultrasonic generating element includes a frame including a through hole in its central portion, a first transducer being flat-shaped and bonded to a first principal surface of the frame, and a second transducer being flat-shaped and bonded to a second principal surface of the frame and is configured to generate ultrasonic waves in a buckling tuning-fork vibration mode where the first transducer and the second transducer vibrate in mutually opposite phases. The first acoustic path is disposed so as to be adjacent to at least one of both principal surfaces of the ultrasonic generating element and configured to compress the ultrasonic waves generated from the ultrasonic generating element and to allow the ultrasonic waves to propagate therethrough in a direction along the principal surface of the ultrasonic generating element.
