The invention discloses a music flashing light controller and a control system and method thereof. The music flashing light controller comprises a central control module, a plurality of executing modules, a plurality of light-emitting units, a power supply module, a music coding module, a player, a signal acquiring module and a signal analyzing module, wherein flashing lights are controlled to be switched on or off with the music, show a music light show effect, and are flexible in forms; and the player is not needed to be in wired connection with the signal acquiring module. The music flashing light controller has the advantages of low construction difficulty, convenience in installation, and capability of effectively reducing the cost; a music flashing light control system adopting the music flashing light controller is capable of flexibly increasing or reducing lamp banks, and has the advantage of strong expansibility. The invention also provides a control method of the music flashing light controller, and the control method ensures that the flashing lights are switched on or off with the music.

The embodiment of the invention discloses a video music matching method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining the image features of all image frames in a to-be-matched video, and determining the image change features of the to-be-matched video according to all image features; acquiring audio features of each alternative audio, and determining rhythm change features of each alternative audio according to each audio feature; and according to the similarity between the rhythm change characteristics of the alternative audios and the image change characteristics of the to-be-matched video, selecting the matched audio of the to-be-matched video from the alternative audios. According to the technical scheme provided by the embodimentof the invention, the change of the video content is matched with the change of the music rhythm, and the content expression of the video is accurately highlighted, so that when a user watches the video, the resonance of the user is more easily caused, and the watching experience of the user is improved.

The invention discloses a control method for enabling an LED lamp to flash along with music and a music rhythm flashing lamp. The control method comprises the steps that firstly, a microphone receives acoustic waves and ultrasonic waves; secondly, an ultrasonic wave detecting circuit receives ultrasonic waves sent by the microphone, and when the ultrasonic wave at a specific frequency is received, an electrical signal is generated; thirdly, a master control circuit enables a signal amplifying circuit to be closed and controls the ultrasonic wave detecting circuit to be in the dormant state at the same time; fourthly, acoustic waves received by the microphone are converted into electrical signals by the signal amplifying circuit, wherein the acoustic waves at different frequencies are converted into different electrical signals; fifthly, the master control circuit controls shining and extinguishing of the LED lamp according to the electrical samples obtained in the fourth step. By the adoption of the control method for enabling the LED lamp to flash along with music, the LED lamp can be automatically turned on through the ultrasonic wave at a specific frequency, the LED lamp can shine, be extinguished and change brightness along with change of the frequency of the acoustic wave, and therefore the purpose that the LED lamp flashes along with music is achieved.

Musical rhythm, is taught using a sequenced rhythm pattern, wherein a user's strike within a time window around each note maintains suppression of audible output. If a strike falls outside the time window, output resumes. FIG. 2 shows a smartphone / tablet app. Pad 13 is struck in harmony with a rhythmic pattern on display 1. Means 3 to 11 adjust app parameters. Means 2 control rhythm. A display preferably shows current and past states of the system during a session (e.g. metronome suppressed, metronome non-suppressed, strike detected in time window, strikes outside time window), as well as time remaining in the current session, as either a ‘clock’ or ‘pie chart’ type, or rectilinear ‘bar’ type, the ‘time remaining’ segment of the display being progressively replaced by sections e.g. of differing colour or texture corresponding to the current state, with the ‘time past’ segments displaying the past states.
