Abstract

This invention relates to a method to make digital music play relative music according to movement, which adds vibration sensor in player with beat frequency label; the vibration sensor senses the vibration signals and the central processor computes out movement beat frequency to select music play; if user movement frequency changes, the central processor judges whether to re-select music play.

Description

Make digital music player play the method for corresponding rhythm music by movement rhythm

Technical field

The present invention relates to a kind of method that makes digital music player play the corresponding rhythm music automatically by movement rhythm.

Technical background

The develop rapidly of electronic technology in recent years makes the digital music player increased popularity, and their volumes are little, capacity is big, function is strong, and the also built-in vibration perceptron of some player has step function.Development of electronic technology also makes computer that the automatic accuracy of identification of music rhythm is further improved.

The rhythm of music has very big influence to sporter's motion process, and suitable rhythm makes the relaxation and happiness that become of moving.The motion of different rhythm needs different rhythm music.But present digital music player does not possess the function of playing the corresponding rhythm music by movement rhythm automatically, and what the sporter can only be manual selects melody to cooperate current movement rhythm.If run duration is long or movement rhythm changes, this process of selecting repeats again and again, and consuming time taking great energy makes the sporter often abandon selecting and make the effect of music have a greatly reduced quality.

Summary of the invention

The objective of the invention is to overcome above-mentioned 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.

For achieving the above object, the technical solution adopted in the present invention is:

In the hardware of digital music player, increase the vibration perception component.

Melody is carried out rhythm identification pre-service, and melody is added the rhythm frequency mark.

The vibration signal of vibration perception component collection calculates the rhythm frequency that the user moves via central processing unit,

Central processing unit is a standard with this frequency, plays according to the melody that default rule is selected to have the corresponding rhythm frequency,

When user's movement rhythm frequency changes, perhaps judge whether recomputate the movement rhythm frequency, select corresponding melody to play according to signal and default rule that the vibration perception component transmits by central processing unit; Perhaps whether recomputate the movement rhythm frequency, select corresponding melody to play by user's ACTIVE CONTROL.

Advantage of the present invention is: the player carrier can hear at any time at the volley and be fit to the music of movement rhythm at that time, makes the whole motion process relaxation and happiness.

Embodiment

Below in conjunction with embodiment, the invention will be further described.

The vibration perception component of player adopts the high sensitivity integrated circuit acceleration transducer that does not have bascule, and it can change in the small action of perception.

The melody that is stored in the player music libraries is analyzed according to presetting method by central processing unit, calculates the frequency of playing of melody, and this melody is made to go up the rhythm frequency mark.In addition, also can directly the melody input player music libraries of rhythm frequency mark will be had.

Player is provided with state switch, player can be switched between normal state and vibration perception state of the present invention.The user carries the player setting in motion that is under the vibration perception state, acceleration transducer transmits vibration data to central processing unit, central processing unit is got rid of the interference of anomaly number certificate according to default disposal route, calculates the frequency of user's movement rhythm.With this frequency is standard frequency, cooperates suitable tolerance, and central processing unit selects corresponding melody to play or generate playlist.

In the playlist that generates, the melody that rhythm frequency is identical with standard frequency comes first of playlist, rhythm frequency is second that the melody of 2 times of standard frequencies or 1/2 times comes playlist, and rhythm frequency is the 3rd that the melody of 4 times of standard frequencies or 1/4 times comes playlist.Because multiple is greater than 4 times or have little significance for motion less than 1/4 times melody, so remaining melody random alignment is positioned at the 5th of playlist in all music libraries.Player is play according to tab sequential.

After user's motion frequency took place to change significantly and continues for some time, central processing unit recomputates user's motion frequency, reselect melody play or generates playlist.Establish reset button on the player in addition, when the user changes motion frequency, can manually make player recomputate user's motion frequency, reselect the melody broadcast or generate playlist.

Claims

1. one kind makes digital music player play the method for corresponding rhythm music by movement rhythm, and its digital music player that adopts comprises the vibration-sensing assembly, and its melody that adopts has the rhythm frequency mark, the method is characterized in that implementation step is as follows:

(1) vibration signal of vibration perception component collection calculates the rhythm frequency that the user moves via central processing unit,

(2) central processing unit is a standard with this frequency, play according to the melody that default rule is selected to have the corresponding rhythm frequency,

When (3) user's movement rhythm frequency changes, perhaps judge whether carry out above step again according to signal and default rule that the vibration perception component transmits by central processing unit; Perhaps whether carry out above step again by user's ACTIVE CONTROL.
