Abstract

PURPOSE:To obtain wide-band characteristics with low impedance by arranging two piezoelectric ceramic plates in the lengthwise direction of an inflection oscillation transducer and at right angles to the displacement direction while their residual polarization directions are opposite. CONSTITUTION:Between constantly elastic metallic plates 10 and 11 made of ironnickel alloy, piezoelectric ceramic plates 13 and 14 performing thickness slide oscillation are sandwiched in parallel, while their residual polarization directions 15 and 16 are opposite, and connected together being soldered. The electrode parts 17 of the piezoelectric ceramic plates 13 and 14 are edged to prevent short circuits with the metallic plates 10 and 11. Then, a lead wire from one electrode part of the ceramic plate 13 and another lead wire from one electrode part of the ceramic plate 14 are short-circuited into a lead wire 18 and when an AC voltage applied between it and a lead wire 19 from the common electrode part of the two ceramic plates, slide oscillations are performed by the ceramic plates as shown by arrows 20 and 21, so tht the transducer performs inflection oscillation as shown by dotted lines.
