The digital signal controls the analog circuit, and the light-emitting unit 21 is controlled by the dimming unit 232 to convert the light-emitting brightness or color. For example, the change of the light-emitting brightness of the light-emitting unit 21 can be divided into five brightnesses from full dark to full bright, and each time a vibration is sensed, the dimming unit 232 can control the light-emitting unit 21 to convert a brightness; The change of the illuminating color of the illuminating unit 21 is divided into seven kinds of changes such as pink, red, orange, blue, light blue, green and yellow, and each time a vibration is sensed, a color is converted, and when the shaking is stopped, the sensing is performed. When the light-emitting unit 21 is in a stationary state, the color or brightness is locked. Herein, the changes in the light-emitting luminance and the light-emitting color of the light-emitting unit 21 are merely examples, and are not available to limit the creation.
