Abstract
Methods and apparatus for improving the acoustical performance associated with a speaker, such as a piezoelectric speaker, are disclosed. According to one aspect, an apparatus includes a substrate, a can mounted on the substrate, and a piezoelectric speaker arrangement. The piezoelectric speaker arrangement is at least partially mounted on the can. In one embodiment, the substrate is a printed circuit board (PCB) and the can is an electromagnetic interference (EMI) shielding can.
