Play the very big variation on the effect.This variation has only very little may produce positive effect
Really.Under present scientific and technological background, software can't be write out artistic work, and a head is by software
The music of revising will inevitably be had a greatly reduced quality to the beneficial effect of motion.
Summary of the invention
The objective of the invention is to overcome aforementioned weak point, for people provide a kind of method that makes digital music player play the corresponding rhythm music automatically by user's movement rhythm, it can select the adaptive user's of music who is in step with the movement rhythm height motion, makes motion become a kind of enjoyment as dancing.
Employed digital music player is except comprising storer, processor, and audio output unit, input block, and outside the Power Management Unit, at least also include sensor module.
For achieving the above object, the technical solution adopted in the present invention is that implementation step is as follows:
(1) perceive motion signal,
(2) calculate movement rhythm according to motor message,
(3) be as the criterion with movement rhythm, select to have the music file broadcast that corresponding bat carries out speed,
(4) when movement rhythm changes, carry out above all or part of step again.
Described sensor module can be mechanical, for example microswitch; Also can be electronic type, for example acceleration transducer, pressure transducer, photoelectric sensor etc., audio sensor, flow sensor etc.
Described movement rhythm is meant the number of times of the periodicity action of finishing in the unit interval.
Described bat carries out speed, is meant the bat number of playing back music in the unit interval.
The bat of music carries out speed can calculate (the method for putting down in writing in following network address for example: http://music.ee.ntu.edu.tw/beat_tracking.htm by default methods analyst by processor; The method put down in writing of Chinese patent CN 88 2 02072 u for example again); Perhaps directly use to have the music file (seeing that application number is 200510021724.5 patented claim) that bat carries out the speed mark, perhaps use is corresponding with melody, contains the file that this melody bat carries out rate information.
Processor is according to movement rhythm, and specific tolerance and specific corresponding relation are selected music file by first-selection and play, or generates playing sequence tabulation broadcast again.This corresponding relation is seen (a).(a) nX-A≤Z≤nX+A or X/n-A '≤Z≤X/n+A '
X: movement rhythm n: non-zero natural number Z: bat carries out speed A: tolerance (non-negative) A ': tolerance (non-negative)
Movement rhythm X comprises two types, and a kind of is instant movement rhythm X ', and a kind of is mean motion rhythm X ":
(b)1/t＝X′
T: the duration X ' in individual signals cycle: instant movement rhythm X ": mean motion rhythm n: non-zero natural number
In practical operation, can only use wherein a kind ofly, also can two kinds be used.Two kinds when being used, mean motion rhythm X " be used to select melody, instant movement rhythm X ' is used for mean motion rhythm X " is with relatively to judge whether that this reselects the melody broadcast.
Tolerance is more little, and the music file of selecting is few more, and the beat of music file carries out speed more near movement rhythm.Under less tolerance, the user finely tunes the music that oneself movement rhythm can and play and is in step with fully.Therefore, alternative melody quantity is the bigger the better; Under the prerequisite that can select the right quantity music file, tolerance is the smaller the better.
When generating the playing sequence tabulation, selected melody sorts according to ad hoc fashion.For example, can come the front by the melody that the n value is less; Perhaps, melody is staggered according to the size of n value; Perhaps with the melody random alignment.In the practical operation, the value of n is big (as n≤4) too.
Processor calculates on the backstage and the monitoring movement rhythm, and when the variation of movement rhythm surpasses particular value, and after this variation continued specific duration, the step before then getting back to circulated; Perhaps by the user when changing movement rhythm, ACTIVE CONTROL circulates the step of processor before getting back to.
Advantage of the present invention is: the player carrier can enjoy the music of being in step with the movement rhythm height at the volley at any time, makes the whole motion process relaxation and happiness.
