The audio signal for stating sound to be played is modulated according to R channel, obtains the second audio signal corresponding with R channel.
In the optional embodiment, distance value and user by ambient noise value, user terminal and user's ear
The current media volume value of terminal is modulated the main Oscillation Amplitude and/or vibration frequency included to audio signal to audio signal
The modulation of rate, can either ensure user heard in more noisy environment user terminal play sound, and can enough ensure to
User brings relatively good stereophonic effect.
In another optional embodiment, when step 203 testing result for it is no when, and perform step 204 it
Before, following operation should can also be included based on the method for sound channel control audio signal transmission：
User terminal detection has whether the application of sound broadcasting demand is that privacy classes are more than or equal to default privacy classes
A certain application, when the application for detecting that sound plays demand is a certain application, detection is corresponding with sound broadcasting demand
Whether contact person is to preset one of them in important relation people, when weight is artificially preset in the contact for detecting sound broadcasting demand
When wanting one of them in contact person, triggering performs the behaviour that the head feature of user is identified above by the camera of user terminal
Make.
It is further alternative, wherein one in detecting that sound plays the artificial default important relation people of contact of demand
, should be based on sound channel control audio letter after individual, and before the head feature of user is identified by the camera of user terminal
Number transmission method can also include following operation：
User terminal detects in the particular content of sound to be played whether include preset keyword, is somebody's turn to do when detecting to include
During preset keyword, triggering performs the operation that the head feature of user is identified above by the camera of user terminal.
In another optional embodiment, it should can also be included based on the method for sound channel control audio signal transmission following
Operation：
Whether user terminal detection user terminal is in mobile status, when detecting that user terminal is in mobile status,
Retriggered performs above-mentioned steps 204- steps 208, can also retriggered execution step 204, step 206 and step 208.
So can be according to the position of mobile status real-time tracing user's human ear of user, to ensure the stereophonic effect of user.
It can be seen that the method based on sound channel control audio signal transmission implemented described by Fig. 2 can be by the head that identifies
Portion's feature determines the position of human ear, and by corresponding audio signal orientation passes respectively with L channel and R channel after modulation
The left ear of user and the auris dextra of user are transported to, so user can not only be allowed to experience stereosonic effect, ensure that user
Audio experience, additionally it is possible to the privacy of transfer voice is improved by way of directional transmissions, improve user use body
Test, and the wearing state of earphone and earphone is detected before the head feature of user is identified by camera, and
It is not detected by and establishes the earphone of wireless connection with user terminal or when earphone is not in by wearing state, is just identified by camera
The head feature of user, advantageously reduce the power consumption of user terminal.
Embodiment three
Referring to Fig. 4, Fig. 4 is a kind of structural representation of user terminal disclosed in the embodiment of the present invention.As shown in figure 4,
The user terminal 400 can include detection unit 401, recognition unit 402, determining unit 403, modulating unit 404 and orientation
Transmission unit 405, wherein：
Detection unit 401, for detecting whether there is sound to play demand.
Recognition unit 402, for when detection unit 401 has detected that sound plays demand, passing through user terminal 400
Camera identifies the head feature of user.
Detection unit 401, the facial characteristics inspection that the above-mentioned head feature for being additionally operable to be identified according to recognition unit 402 includes
Survey whether user is authorized user.
Determining unit 403, for when it is authorized user that detection unit 401, which detects user, being known according to recognition unit 402
The above-mentioned head feature not gone out determines that the left ear of user is relative relative to the first position of user terminal 400 and the auris dextra of user
In the second place of user terminal 400.
Modulating unit 404, for being modulated to the audio signal of sound to be played according to L channel and R channel, obtain
The first audio signal corresponding with the L channel and the second audio signal corresponding with the R channel.
Directional transmissions unit 405, for being determined according to left ear of the above-mentioned first position that determining unit 403 is determined to user
Obtained above-mentioned first audio signal and determined according to determining unit 403 above-mentioned the are modulated to transmission modulating unit 404
Obtained above-mentioned second audio signal is modulated to the auris dextra directional transmissions modulating unit 404 of user in two positions.
It can be seen that the user terminal 400 implemented described by Fig. 4 can determine the position of human ear by the head feature identified
Put, and corresponding audio signal directional transmissions will be distinguished to the left ear and use of user with L channel and R channel after modulation
The auris dextra at family, so user can not only be allowed to experience stereosonic effect, ensure that the audio experience of user, additionally it is possible to pass through
The mode of directional transmissions improves the privacy of transfer voice, improves the usage experience of user.
In an optional embodiment, determining unit 403, it can be also used in modulating unit 404 to sound to be played
Audio signal be modulated according to L channel and R channel, obtain the first audio signal corresponding with the L channel and with this
Before second audio signal corresponding to R channel, ambient noise value, the user terminal 400 of the local environment of user terminal 400 are determined
