Abstract
Systems for generating audible sound, including one or more elongate rods attached to one or more flexible membranes, such that longitudinal vibrations of the rods cause vibrations of the membranes, thereby producing audible sound. In some cases, an input audio signal may cause an electromotive actuator to vibrate, and the actuator may be coupled to one of the elongate rods. In some cases, one actuator may be provided for each elongate rod. In some cases, each actuator may receive a different channel of a multi-channel audio signal, such as a stereo signal.
