ARM microprocessor transmits signal to the acceleration sensor circuit at an interval of 40 milliseconds to collect acceleration value of the user. The microprocessor presets threshold value for illuminating and dimming, and generates the second signal after analysis and evaluation of the acceleration value. When the acceleration value exceeds threshold value for illuminating, the microprocessor generates the second signal to illuminate the LED light through the LED light driver circuit. When the acceleration values is below threshold value for dimming, the LED light dims automatically. When the acceleration value falls between the threshold values for illuminating and dimming, the LED light remains in original state of illumination. When one is in motion, acceleration value is in constant change with it on the high side when the foot steps back on or bounces off the ground and on the low side when the foot moves in the air. Thus, the light illuminates when the foot steps back on the ground and dims when it bounces off the ground. Therefore, the LED light equipped on the earphone illuminates and dims on real time with the motion of the user.
