ABSTRACT:

SUMMARY OF THE INVENTION
Embodiments of the present invention advantageously satisfy the above identified need in the art, and provide acoustical antennas which are low in edge diffractions and side lobes. In particular, an embodiment of an inventive acoustical antenna comprises a body, which further comprises a skirt, and a serrated-roll edge.
In a preferred embodiment of the present invention, the antenna body is tightly jointed with the body or the supporting structure of its hosting acousducer. Irregularities of the antenna body and the joint to its host will create internal reflections, which disturbs the sound generated by the acousducer. In a further preferred embodiment, the antenna body and the joint all are smooth and continuous. Any unavoidable irregularities should be kept as minimum as possible.
