Method for automatically switching incoming call signal output mode from vibration to ringtone using vibration detection unit in mobile communication terminal
First Claim
1. A mobile communication terminal, comprising:
- a vibrator configured to generate vibration when an indication mode is set to a vibration mode;
a speaker configured to output an audible sound when the indication mode is set to a ringtone mode;
a vibration detection sensor configured to measure an actual intensity of vibration of the terminal changed according to external circumstances of the terminal when the vibrator operates and to detect an intensity of energy supplied to drive the vibrator; and
a controller configured to calculate a vibration transfer energy transferred to an outside of the terminal using both the measured actual intensity of the vibration and the detected intensity of energy, and to output an indication mode control signal,wherein the controller outputs the indication mode control signal for switching the indication mode of the terminal from the vibration mode to the ringtone mode when the calculated vibration transfer energy is lower than a reference value.

Abstract
A method for automatically switching an incoming call signal output mode in a mobile communication terminal is disclosed. The method comprises the steps of determining whether or not a present incoming call signal output mode is a vibration mode when receiving incoming call, driving a vibrator to output vibration if it is determined that the present incoming call signal output mode is set to the vibration mode, detecting an intensity of actual vibration of the terminal via a vibration detection sensor when the vibration is output, followed by calculating transfer energy using the intensity of the actual vibration on the terminal, and automatically switching the incoming call signal output mode from the vibration mode to a ringtone mode according to comparison of the calculated transfer energy with a reference value. With the method, a user can easily recognize the incoming call signal.
