Abstract
An electronic device and method of operating comprises a housing; a base coupled to the housing; and an electro-mechanical transducer coupled to the base, the electro-mechanical transducer configured to operate in a resonant mode and output a haptic effect upon receiving a drive signal at a predetermined drive frequency. In an embodiment, the electro-mechanical transducer further comprises a plurality of electro-mechanical transducers, each electro-mechanical transducer configured to operate in its respective resonant mode and output a respective haptic effect upon receiving a drive signal having a predetermined drive frequency. Alternatively or additionally, the electro-mechanical transducer further comprises a plurality of spaced apart electro-mechanical devices coupled thereto in a serial fashion between a first end proximal to the base and a second end distal to the base.
