Show affiliationsThis paper presents an experimental study of the shallow spherical shell piezoceramic RAINBOW actuator, to follow up the theoretical modeling and numerical studies of this actuator reported in a previous paper. A comparison of theoretically predicted and experimentally determined natural frequencies of the RAINBOW actuator with free edge boundary conditions is presented in the paper. Also presented are results from experiments performed on a prototype of a low profile piezoelectrically driven baffled acoustic piston developed at the Smart Trim Technology Laboratory. Experimentally generated volume velocity curves of the piston are presented. The possible use of this device in active noise control applications is discussed.
