Abstract
A method and apparatus for generating vibration based on sound characteristics in a mobile terminal are provided. The method includes converting audio data into an audio signal upon generation of a sound play request; determining whether to generate vibration based on a sound volume of the audio signal; setting an actuator to be driven for the audio signal among at least two actuators based on frequency distribution characteristics of the audio signal if it is determined upon determining to generate the vibration; and driving the actuator being set for the audio signal when outputting the audio signal.
Claims14
An apparatus for generating vibration based on sound characteristics in a mobile terminal, the apparatus comprising:
- at least two actuators including first and second actuators for generating vibration;
- an actuator driver for driving the actuators to vibrate according to an actuator drive signal;
- an audio unit for converting audio data into an audio signal upon generation of a sound play request and outputting the audio signal to an audio output device;
- and
- a controller for determining whether to generate vibration according to whether a sound volume of the audio signal exceeds a reference sound volume, setting an actuator to be driven for the audio signal among the at least two actuators based on frequency distribution characteristics of the audio signal and a respective response time of each of the at least two actuators upon determining to generate the vibration, and generating the actuator drive signal for driving the set actuator to vibrate while the audio unit outputs the audio signal to the audio output device,
- wherein the response time of an actuator indicates a time taken for an intensity of vibration generated by driving of the actuator to reach a first predetermined vibration intensity from a second predetermined vibration intensity.
