Abstract
The electroacoustic transucer comprises a dome-shaped carrier on whose inner side are mounted piezoelctric elements and which furthermore is also provided with piezoelectric elements on its outer side. The piezoelectric elements on the inner and on the outer side are switched in separate groups and can be triggered such that the sound waves produced by them can be synchronized, by which means the power intensity in the focus can be increased.
