Step 11, the current motion state of user is sensed by magnetometric sensor.
Specifically, user carries the terminal with magnetometric sensor, magnetometric sensor is held to the motion state of user
Continuous detection.In the present embodiment, the movement rhythm of user is predominantly detected, is such as run.Thus, it is usually required mainly for obtain human body amplitude
Change information.Embodiment is as follows：
One piece of magnet is arranged on earphone, specific position is not limited, and the working face of earphone upper magnet has two kinds of poles of N, S
Property, when human motion, earphone motion is driven, the magnetic field that the contained magnet of earphone is produced can pass through the surface of magnetometric sensor, when
When earphone is with man-machine tempo variation, the relative position of magnet and magnetometric sensor in earphone also changes, and constitutes one
The magnetic field of change, i.e.,：The size of magnetic field intensity also changes within the specific period, can produce electrical potential difference, magnetic force sensing
Device is judged the electrical potential difference of special time, it can be deduced that human body is with specific tempo variation.From the point of view of experimental data,
When the magnet and the distance of magnetometric sensor on earphone are 50 centimetres, when magnetic field intensity is 1000 tesla, electrical potential difference exceedes
During 5V, it is believed that the displacement of earphone is the displacement of the running generation of human body.
In addition, the electrical potential difference more than 5V is in 1 second, the rhythm changed repeatedly is more than 4 times, you can existed with being inferred to human body
Jog；During more than 6 times, hurried up with being inferred to human body.It is above-mentioned to be recorded by the counter of magnet sensor, generation fortune
Dynamic amplitude.
Step 12, the sensing data of the sensor is handled, motion amplitude versus time curve is obtained.Specifically,
The magnetometric sensor can be obtained motion amplitude and be changed with time song by classical blending algorithm
Line.
Step 13, calculated according to the change curve and obtain motion frequency；
Motion frequency is obtained specifically, being calculated according to the change curve, so as to learn the human body variation rule of user.
Step 14, according to the mapping table of motion frequency and state value, user's current state value is determined.
In addition, in order to be able to play out suitable music from terminal, store in the terminal on user's current state with
The corresponding relation of music, for example, when user is in relatively slow motion state, to play the music releived, and works as user
When handling allegro motion state, strong, the cheerful and light-hearted music of rhythm is played.Thus, the shape for representing user movement state
State value has the music that multiple, different values represent different rhythm.Thus, when obtaining user's current state according to sensing data
After value, the selection standard of music file just can be determined, so as to select suitable music.
On the mapping table of motion frequency and state value, because user is different, even at equal state, it is moved
Frequency has certain difference, even if same user, and each motion frequency when being likely to be at same state also has
Certain difference, thus, according to many experiments, the different motion frequencies of same state are obtained, so as to obtain same shape
The corresponding motion frequency scope of state.Thus, the mapping table of the motion frequency and state value can essentially be motion frequency
The mapping table of rate scope and state value.After motion frequency is obtained according to change curve calculating, by the motion frequency
Rate is compared with predetermined threshold value (two end values up and down of a certain motion frequency scope), so that it is determined that current kinetic frequency belongs to
In which motion frequency scope；According to the scope, phase is determined in the mapping table from the motion frequency with state value
The state value answered.For example, the mapping table of motion frequency and state value is as shown in table 1, it should be noted that, the data in the table
Only as a kind of example, not normal data, motion frequency scope is also suitable because of people, with different setting values.

Album name；F M13i：Artist name；F M14i：Movement rhythm.As shown in table 2：
Table 2
Different features, the discrete set of its characteristic value is different, for example, for this feature of FM11i, because it represents sound
Only one of which value in music file title, its usual characteristic value collection, there is the music file of alias for some, such as, different languages
The title of speech, might have multiple values.For F M13i, it represents artist name, for same first song, might have different
Singer sings, and thus, the name of all singers is had in its characteristic value collection.
User's current motion state of the present invention is one of feature, it is assumed that the character string of the feature is
FM14i, obtained state value is then characterized a particular value in value set.The set of state value i.e. described in table 1 is
This feature value set.
Audio index sequence number S (n) can be determined by one or more of characteristic set characteristic value, for example, S
(n)={ FM [n (mi)] }, just can be with when the characteristic value of one of feature is different from the characteristic value in other call numbers
Index number is determined, if identical characteristic value, then compares other characteristic values, until distinguishing index number.
For example：In artist name this feature, for the singer of a determination name, then the characteristic value of this feature is true
It is fixed, but might have a plurality of index and meet this feature, it is now continuous using new in the index aggregate relay for meeting this feature
Feature distinguish, such as other features of album name.
In the disclosed embodiments, premised on the characteristic value of other features in this feature set is for known to, i.e., true
During accordatura music file, the characteristic value of other features has been known parameters.For example, for user before running, having set will
