This abstract first appeared for US patent application 18829640 titled 'ULTRASONIC TRANSDUCER AND PARAMETRIC SPEAKER INCLUDING THE SAME

Original Abstract Submitted

A dimension in a longitudinal direction inside one or more frame bodies is equal to or greater than four times a dimension in a short direction orthogonal or substantially orthogonal to the longitudinal direction inside the one or more frame bodies and is greater than a minimum dimension in the longitudinal direction of one or more ultrasonic vibrators. An average length in the longitudinal direction of a gap between an edge on at least one side in the longitudinal direction of an inner circumferential surface of the one or more frame bodies and an edge on the at least one side in the longitudinal direction of a surface of the one or more ultrasonic vibrators on a frame body side is equal to or less than about 1.3 times a dimension in the short direction inside the one or more frame bodies.
