ABSTRACT:
An acoustic transducer with a piezoelectric acoustic oscillator member that has a first surface with a common electrode, and a second surface with a predetermined electrode pattern. In some instances the electrodes are individually connected off of the transducer. In other instances some of the electrodes are connected together in sets. Each set is then connected off of the transducer. The individually connected electrodes are connected to an adjacent pedestal supporting a pad that is adapted to be soldered or wired to a wire member. When the electrodes are connected together in sets, the connecting member is supported on a plateau or pedestal so that a wire may be connected to any part of the connector. In one preferred embodiment, where two sets of electrodes are connected to two connectors, the connectors are parallel conductive side rods positioned on opposite edges of and adjacent to the oscillator member.
The connectors or pads are sufficiently built up that the electric field produced by voltage distributions on such connectors or pads, and they do not influence the steering of the acoustic beam launched by the transducer.
