摘要:
A method is provided for abruptly stopping a vibration motor providing tactile feedback (406) to the user of a portable communication device (100). The method comprises providing a drive waveform (401) including an attack signal (402), and a stop signal (411) out of phase with the attack signal (402), to one of the vibration motor (235) or the multi-function transducer (130) to quickly stop the vibration. The drive waveform may include an optional sustain signal (407) subsequent to the attack signal (402) and prior to the stop signal (411). A file stored in memory (212) is accessed to provide the drive waveform (401).
