Latest Patents

Kanai's latest patents include innovative designs for piezoelectric transducers. The first patent describes a piezoelectric transducer with electrodes formed on both surfaces. This transducer features a piezoelectric base molded as a curved plate, which can converge sound fields of acoustic waves at an arbitrary point. It effectively reduces noise or reverberation in a lateral direction caused by unnecessary vibrations. Notably, at least one of the electrodes is divided concentrically, and the piezoelectric material used is preferably porous PZT, which has a small electromechanical coupling factor in the lateral direction.

The second patent involves a piezoelectric transducer composed of multiple elements that generate mechanical vibrations converging substantially on one point. This design allows for control over the convergent point by insulating the piezoelectric transducer elements mechanically, arranging them concentrically, and driving them independently and separately from each other.
