In step s101, the target position of active user is obtained.
With the development of technology, terminal has been not only a kind of means of communication, while being also a kind of converter tools.User
Often using terminal listens to music or sees video etc..When user needs using terminal to play audio file, in order to avoid
The sound put outside interferes other users or audio content is learnt by other users, and the user usually needs to use earphone
Listen audio.However, listening its operation of audio relatively complicated using earphone.
In the step S101 of the embodiment of the present application, for example, terminal, which can be obtained first, to be worked as when needing to play audio file
Position where preceding user, i.e. target position.
In step s 102, the first frequency for needing the audio played is obtained.
For example, after getting the target position of active user, the frequency of the available audio for needing to play of terminal, i.e.,
First frequency.
In step s 103, according to the target position and the first frequency, at least two ultrasonic frequencies are determined, and are
Different preset components distributes the different ultrasonic frequencies in the terminal.
For example, terminal can after the first frequency for the audio that the target position and needs for getting active user play
To determine at least two ultrasonic frequencies according to the target position and first frequency.Then, terminal can will be determined not
Same ultrasonic frequency distributes to different preset components.That is, the number for the ultrasonic frequency determined and of preset component
Number is equal.
In step S104, the preset component is controlled according to the ultrasonic frequency being assigned to towards the target position sending sound
Wave, so that ultrasonic frequency is mixed in the target position and parses the first frequency.
For example, terminal can control each default portion after being assigned with different ultrasonic frequencies for different preset components
Part issues sound wave according to the target position where the ultrasonic frequency towards active user being assigned to, so that all ultrasonic wave frequencies
Rate is able to carry out mixing in the target location, and parses first frequency, so that active user be enable to hear terminal plays

Sound wave, therefore the present embodiment will not interfere the user in other regions.
Referring to Fig. 2, Fig. 2 is another flow diagram of the playback method of audio provided by the embodiments of the present application, process
May include:
In step s 201, when detecting that active user needs to play the file comprising audio, when terminal obtains current
Between.
For example, terminal is available first to be obtained currently when detecting that active user needs to play the file comprising audio
Time.For example, terminal detects that active user picks up terminal, when having selected a song and click play button, terminal can be with
First obtain current time.
After getting current time, terminal can detecte whether the current time belongs to preset working time section.Example
Such as, preset working time section is workaday 9:00 to 18:00.It is understood that working time section can be by user certainly
Row setting, such as also can be set as 08:30 to 17:30, etc., it is not specifically limited herein.
In one embodiment, calendar used in terminal has the mark on working day and festivals or holidays, then obtaining
To after current time, terminal the current time corresponding date can be compared with the date in calendar, when judging current
Between the corresponding date whether belong to working day.
If judging, current time is not belonging to preset working time section, for example current time is not belonging to workaday work
Period, then terminal can directly play the file that this includes audio.For example, in the case where being not connected to earphone, eventually
End directly can put the audio using loudspeaker outside.
If judging, current time belongs to preset working time section, then can enter step in S202.
In step S202, if detecting, the current time belongs to preset working time section, and terminal is taken the photograph by wide-angle
As mould group obtains the image of this terminal surrounding.
For example, the current time that terminal is got is the morning 10:00 of Monday, belong to workaday working time section, that
Terminal can obtain the image of this terminal surrounding by wide-angle imaging mould group.For example, active user's handheld terminal, and terminal
Plane on the vertical direction at place and the plane on the vertical direction where user are close to parallel, then terminal can open
Image around the shooting of wide-angle imaging mould group.
After getting the image of this terminal surrounding, terminal can judge that this terminal surrounding whether there is according to the image and work as
Preceding other users with open air.
If judging this terminal surrounding, there is no other users outside active user, then terminal can execute other behaviour
Make.For example, terminal directly can put the audio using loudspeaker outside in the case where being not connected to earphone.
If judging this terminal surrounding, there are other users outside active user, then can enter step in S203.
In step S203, if according to the image determine this terminal surrounding there are the other users outside active user,

Receiver or microphone etc..
In step S207, terminal control preset component is according to the ultrasonic frequency being assigned to towards target position sending sound
Wave, so that ultrasonic frequency is mixed in the target position and parses first frequency.
For example, after two ultrasonic frequencies that will be determined are respectively allocated to two different preset components, terminal
Each preset component be can control according to the ultrasonic frequency being assigned to simultaneously towards the target position sending sound where active user
Wave so that all ultrasonic frequencies are able to carry out mixing in the target location, and parses first frequency, to make current
User can hear the audio of terminal plays.
In the present embodiment, when obtaining the target position of active user, terminal is available to utilize range sensor, obtains
Take the target range between active user and terminal.Then, terminal can be according to the target range and the audio for needing to play
First frequency, to determine at least two ultrasonic frequencies.That is, the first frequency in the audio for needing to play is identical
In the case where, if terminal is different from the distance between active user, then it is determined that the ultrasonic frequency come out is also different.For example,
The first frequency for the audio for needing to play is f1, then when the distance between terminal and active user are 30 centimetres, terminal root
According to first frequency f1 and 30 centimetres of distance, determine two ultrasonic frequencies, for example, the two ultrasonic frequencies be respectively f2 and
f3.When the distance between terminal and active user are 40 centimetres, terminal is determined according to first frequency f1 and 40 centimetres of distance
Two ultrasonic frequencies, such as the two ultrasonic frequencies are respectively f4 and f5.Wherein, the ultrasonic frequency group that f2 and f3 is constituted
It closes and combines difference with the f4 and f5 ultrasonic frequency constituted.That is, terminal can according to its between active user away from
From difference, adjustment ultrasonic frequency it is also different, to guarantee that active user can clearly hear in target location by surpassing
The audio for the audible sound that sound wave mixing parses.
In one embodiment, it obtains and works as when detecting that active user needs to play the file comprising audio in S201
