Title: Method and apparatus for audio bass enhancement in a electronic device

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