Embodiment Construction

[0028] The present invention provides a method for automatically flashing a flashlight in an audio playback environment, referring to figure 1 , including:

[0029] Step S1: first open or provide a piece of audio music, and extract the pulse code modulation data of the audio music.

[0030] Step S2: Calculate the extracted PCM data to obtain the real-time value of the rhythm of the piece of music.

[0031] Step S3: Determine the value and compare it with the preset threshold range. If it is within the threshold range, the flashlight will be turned on; if it is not within the threshold range, the flashlight will be turned off, so as to realize the flashing of the flashlight and automatic switching of lighting Features.

[0032] Further, the step S2 includes:

[0033] Sub-step S201: Low-pass filtering is performed on the pulse code modulation data of the audio music, and a variance operation is performed to obtain a rhythm value.

[0034] Sub-step S202: Perform a smoothing a...

Abstract

The invention provides a method and device for enabling a flashlight to automatically flicker in an audio playing environment, and the method comprises the steps: obtaining real-time (FFT) fast Fourier transform data of an audio through the analysis of an audio, setting a threshold value interval, and turning on the flashlight if the audio is in the threshold value interval; and if not, turning off the flashlight, so that the flashlight flickers intelligently and conveniently.

Description

technical field [0001] The invention relates to a method for automatically turning on and off a flashlight, in particular to a method and a device for automatically flashing a flashlight in an audio playback environment. Background technique [0002] For the existing mobile phones currently on the market, if you need to turn on the flashlight, you need to turn on the screen. Through the relevant interface settings of the mobile phone, through the flashlight function, turn on the flashlight and turn it off again; Separate button to activate the flashlight. Along with the popularity of playing software such as music and video, in order to enhance the user's sense of rhythm when listening to music, it is impossible for the user to realize the simplification of opening and closing functions of the flashlight. Contents of the invention [0003] In order to solve the deficiencies and shortcomings in the prior art, the purpose of the present invention is to provide a method for ...
