Abstract

Various embodiments of low-mass sound generators each having a wide frequency band are disclosed. In some embodiments, the acoustic transducer acting as the sound generator is constructed of four layers of PVDF film (16). The top (18) and bottom (20) bi-laminate members are separately formed in a pre-curved manner to form a rippled geometry.
