Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] First, it is necessary to introduce some relevant background technologies.

[0025] figure 1 Shown is the characteristic curve of the audio signal. The volume of the sound wave is shown in the figure. According to the characteristics of the sound wave, the volume heard by the human ear is the amplitude of the up and down vibration of the sound wave, and the envelope of the sound wave is obtained by connecting the highest points of vibration in the positive direction. The envelope basically responds to fluctuations in volume. When the slope of the envelope is large, it represents a rhythm of the music.

[0026] Brightness control for groups of multi-color glowing lights. Light emitting lights, such as light emitting diodes (LEDs), generally have only two states: on or off. The glow light glows when turned on, and turns off ...

Abstract

This invention discloses one lighting set device changing with music, which comprises the following parts: multi-color light set and its driving device to generate square wave signals and to control the lighting status; volume test module and searching list with each line stored with one set of light control parameters to adjust the space occupancy of the signals, wherein the said volume test module is to input volume frequency signals and get its changing rate to generate searching index; the said searching list outputs relative light controlled parameters to the drive device according to the index.

Description

technical field [0001] The invention relates to a device for controlling the brightness and color of a luminous lamp group, in particular to a device for a luminous lamp group that changes with music. technical background [0002] At present, some digital products, such as mobile phones, MP3 players, CD players and other products, usually associate the rhythm of music with LED lights in order to visually produce a rhythm effect when playing music or ringtones. Some major manufacturers now associate the rhythm of music with the on and off of LED light-emitting lights, that is, the LED light-emitting lights are turned on and off rhythmically with the rhythm of music or ringtones. Although this scheme produces a rhythmic change visually, the visual change is relatively monotonous because it only changes in light and dark but not in color. Contents of the invention [0003] The object of the present invention is: aiming at the deficiencies of the prior art, to provide a light...
