Abstract

PURPOSE:To easily work and produce a converging system which is similar to the spherical convergence, by distributing two cylindrical converging systems orthogonal to each other. CONSTITUTION:A crystal 50 is worked into a semicircular column, and a cylindrical hole 60 is formed to the flat plate surface orthogonally to a column shaft. A piezoelectric element 40 is stuck to the column surface to be opposite to the hole 60, and a lead wire or the like is distributed so that the RF electric signal can be applied. In such constitution, the RF electric signal is applied to the element 40. As a result, the element 40 vibrates as a cylinder oscillator, and the generated sound waves are laterally converged. The converged sound wave propagates within the crystal 50 and then receives the longitudinal convergence on a cylindrical interface between the crystal 50 and a medium.
