Abstract
A method of countering a residual resonance experienced by an electronic communication device due to an activation of an actuator within the housing of the electronic communication device. The method includes determining an effective vibration behavior of the electronic communication device when activating the actuator according to a predetermined pattern, determining, based on the effective vibration behavior, a desired counter actuation signal, activating the actuator according to the predetermined pattern for a predetermined period of time, and upon expiration of the predetermined period of time, activating the actuator according to the desired counter actuation signal to counter an residual resonance experienced by the electronic communication device.
