Transducers for focusing sonic energy in transmitting and receiving device
First Claim
1. A transducer for focusing sonic energy comprising, an enclosed housing defining an internal open area, at least one generally concavely curved sonic energy radiating element within said open area in oriented space relationship to at least one arcuate energy reflecting surface, an opening in said housing through which focused sonic energy passes either from or toward said at least one energy reflecting surface and wherein said at least one sonic energy radiating element and said at least one energy reflecting surface are so configured that sound paths from substantially any point along said at least one sonic energy radiating element to said at least one sound reflecting surface and to an area of energy focus exteriorly of said housing are generally equal.

Abstract
Ultrasonic transducers which include at least one internally directed generally concavely configured sonic energy radiating element which directs sonic energy toward at least one arcuate energy reflecting surface which redirects and focuses the energy through an opening in a housing defining the transducer. The configuration of the at least one radiating element and the at least one energy reflecting surface are such that sound waves from substantially any point along the radiating element to the reflecting surface and to a focus exteriorly of the opening are substantially equal. The transducers function to focus energy either as transmitters or receivers.
