Abstract
An electronic device has a shell with an interior, an exterior and a resonant frequency of, for example, 100 Hz. A transducer located in the interior of the shell is operatively coupled to control circuitry. The control circuitry is capable of sending a low frequency audio signal to the transducer which utilizes an electromagnetic force as a source of vibration excitation to cause the shell to vibrate around the resonant frequency of the shell. A low frequency sound is produced by the vibration of the shell.
