Abstract

The transducer of the present invention is diced into sub­ elements which have a height-to-width ratio which deter­ mines the modality of their vibration. The subelements are then electrically connected to provide a transducer having the desired electrical configuration, i.e., an annular array trans­ ducer. Using the present invention, the electro-acoustic characteristics of the transducer are not determinitive of the vibrational characteristics of the individual subelements.
