Multi-function transducers (130, 700) that are suitable for use in
handheld devices such as cellular telephones (100, 900) and are capable
of emitting audio, and generating accelerations of sufficient magnitude,
and at frequencies that can be sensed by tactile sensation and which
exhibit resonant modes that are characterized by center frequencies
within a frequency range that can be sensed by tactile sensation, and
specifically located between two musical notes on a musical scale are
provided. Devices (100, 900) including such transducer are provided, and
methods of operating such transducers are provided.
