Abstract

Aspects of a method and system for processing audio signals for handset vibration are provided. In this regard, an electronic device may control vibrations generated by a vibration transducer based on audio signals processed by the electronic device. The vibration transducer may be started and/or stopped based on the audio signal. For example, the vibration transducer may be controlled based on a rhythm and/or tempo of the audio signal and/or a content type of the audio signal. The electronic device may control a pattern and/or a frequency at which the transducer is started and/or stopped based on the audio signal. An intensity of generated vibrations may be varied based on the audio signal. A duration of the generated vibrations may be controlled based on the audio signal. The vibration transducer may be controlled based on an event occurring on the electronic device that triggered the processing of the audio signal.
