When the highest rhythm of the music of the preset length calculated and the difference of lowest tempo are greater than predetermined threshold value, by the tempo range Nonlinear Mapping of the music of preset length be or level specific pressure to be condensed to the rhythm that pre-sets corresponding with the motion frequency obtained interval.Wherein, the tempo range of the music of preset length is determined by the highest rhythm of the music of this preset length and lowest tempo.
Playing module, for playing the music of preset length according to the rhythm after adjustment.
Further, this device also comprises reminding module, enters the interface of adjustment music rhythm for pointing out user by interactive interface.
Further, adjusting module, can also be used for: according to the rhythm of the music of the fixing rhythm interval adjustment preset length of user's setting.
It should be noted that, the acquisition module in this device can arrange in sensing cell 140 in FIG, and processing module and adjusting module can arrange in controller 180 in FIG, and playing module and reminding module can be arranged in output unit 150 in FIG.
Fig. 4 is the process flow diagram that the present invention adjusts the method for music rhythm, as shown in Figure 4, when needs adjustment music rhythm, comprising:
Step 401: obtain the motion frequency of mobile terminal and obtain the music of preset length.
Wherein, the motion frequency obtaining mobile terminal comprises: the movable information being obtained mobile terminal by acceleration transducer;
The motion frequency of mobile terminal is calculated according to the movable information of the mobile terminal obtained.
Wherein, movable information comprises instantaneous accekeration and the direction etc. of acceleration.The motion frequency calculating mobile terminal according to the direction etc. of instantaneous accekeration and acceleration about how belongs to conventional techniques means well-known to those skilled in the art.
Further, also comprise before the method: prompting user enters the interface of adjustment music rhythm by interactive interface.
Step 402: the rhythm number analyzing the music of the preset length obtained.
Wherein, this step specifically comprises: the number of the single-tone that duration of music of the preset length that statistics obtains is the shortest; Summation operation is carried out to the number of statistics; Numerical value after summation operation is the rhythm number of the music of the preset length of acquisition divided by the value of preset length gained.
Wherein, single-tone refers to the single note in music field.
Step 403: when the rhythm number analyzed and acquisition motion frequency not etc. time, the rhythm of the music of the preset length analyzed according to the motion frequency adjustment obtained.
This step specifically comprises:
Determine the highest rhythm and the lowest tempo of the music of the preset length obtained;
Calculate the highest rhythm of music and the difference of lowest tempo of the preset length determined;
When the highest rhythm of the music of the preset length calculated and the difference of lowest tempo are less than or equal to predetermined threshold value, be the rhythm that the pre-sets interval corresponding with the motion frequency obtained by the tempo range linear mapping of the music of preset length;
When the highest rhythm of the music of the preset length calculated and the difference of lowest tempo are greater than predetermined threshold value, by the tempo range Nonlinear Mapping of the music of preset length be or level specific pressure to be condensed to the rhythm that pre-sets corresponding with the motion frequency obtained interval.Wherein, the tempo range of the music of preset length is determined by the highest rhythm of the music of this preset length and lowest tempo.
It should be noted that how to obtain the tempo range of music, the highest rhythm and lowest tempo and belong to conventional techniques means well-known to those skilled in the art, do not repeat them here.
It should be noted that, according to incompletely statistics, the prehuman musical works tempo range of order is [20,200] in BPM, therefore when the rhythm being mapped to [120,140] BPM is interval, need to adopt linear or nonlinear mapping technique, wherein, Nonlinear Mapping can also be referred to as geometric ratio compression.Such as, the overall tempo range of one section of music is [70,80] BPM, belongs to and changes within 20BPM, then can pass through linear mapping, be changed to [120,130] BPM; The overall tempo range of another section of music is [100,160] BPM, then [100,120] Partial shrinkage is to [120,127], [120,140] Partial shrinkage is to [127,133], [140,160] Partial shrinkage is to [133,140] BPM.That is example above, needs the change considering whole music rhythm, if the rhythm of whole section of music all relatively unifies (changing within 20BPM), then can map directly in joyful interval ([120,140] BPM); As front and back tempo variation is comparatively large, exceedes 20BPM, then needed to carry out geometric ratio compression or Nonlinear Mapping.About how to carry out Nonlinear Mapping or geometric ratio compression and carry out linear mapping, belong to the common practise of this area, be not used for limiting the present invention, do not repeat them here.
Further, when the rhythm number analyzed is equal with the motion frequency of acquisition, the method also comprises: the music of play-overing the preset length of acquisition.
Step 404: the music playing preset length according to the rhythm after adjustment.
Further, the method can also comprise: according to the rhythm of the music of the fixing rhythm interval adjustment preset length of user's setting.Further, the method also comprises: the music playing the preset length obtained according to the rhythm of the music of the preset length after the fixing rhythm interval adjustment of user's setting.
In the inventive method, by the motion frequency adjustment music segments of mobile terminal, the motion frequency achieving the music rhythm after adjustment and user self mates, and enhances the experience sense of user.
