Embodiment

[0017] Embodiment: The sensor adopts an acceleration sensor.

[0018] (1) The user switches the player to the "rhythm recognition" function state to play music,

[0019] (2) The user vibrates the acceleration sensor according to the rhythm of the music,

[0020] (3) The acceleration sensor collects a group (such as 5) motion signals and sends them to the processor. At this time, the music ends.

[0021] (4) The processor calculates the average period or average frequency according to the signal duration and the number of signals,

[0022] (5) The processor stores the calculation result into the memory, corresponding to the music file.

[0023] (6) Continue to process the next piece of music.

Abstract

A music rhythm distinguishing method for digital music player, including: the memory, the the processor, the audio outputting unit, the inputting unit, the power managing unit, and the sensor groupware. The invention is: plays music that the operator makes the same rhythm signal with the music rhythm; the sensor senses rhythm signal; the processor computes the processing speed information of the music time according to the rhythm signal; saves the time processing speed information into the memory according to the corresponding mode with the music file. The invention can achieve the nicety distinguish of the music beat processing speed, gets the better practicability if the invention assorts with application ' the method that the digital music player play the corresponding rhythm music automatically according to moving rhythm' (the application number: 200510021639.9).

Description

technical field [0001] The invention relates to a music rhythm recognition method for a digital music player. technical background [0002] The rhythm of the music, especially the rate of the beat, has a great influence on the movement process of the athlete, and the appropriate rate of the beat makes the exercise easy and pleasant. Movements of different rhythms require music performed at different tempos. [0003] With the rapid development of electronic technology, the computer automatic recognition technology of music rhythm has made great progress, but the speed and accuracy of its recognition still need to be further improved. Under the existing technical conditions, the computer recognition of music rhythm needs to be completely accurate, and the hardware technology still needs to reach a new level. [0004] Closer techniques are: [0005] (1) The method described in the following website: http: / / music.ee.ntu.edu.tw / beat_tracking.htm, [0006] (2) The method descr...
