Execution mode one: based target play sound effect

As an illustrative embodiments, the target play sound effect of audio frequency to be played can be obtained; According to the position of described available audio amplifier, in described available audio amplifier, obtain L channel audio amplifier and R channel audio amplifier that play sound effect is described target play sound effect.In this embodiment, target play sound effect can meet the play sound effect demand of user, thus by meeting situation to available audio amplifier to target play sound effect, chooses appropriate L channel audio amplifier and R channel audio amplifier.

Accordingly, Fig. 3 is the flow chart that a kind of based target play sound effect according to an exemplary embodiment chooses loudspeaker box combination, and as shown in Figure 3, the method can comprise the following steps:

In step 302, all available audio amplifiers are obtained.

In step 304, the position of the available audio amplifier of every platform is obtained.

The above-mentioned step 202-204 shown in step 302-304 and Fig. 2 is consistent, repeats no more herein.

Within step 306, target play sound effect is obtained.

In the present embodiment, target play sound effect can be determined in several ways, below wherein several mode is illustrated.

1) position of target object of reference is obtained; According to the position of target object of reference, determine target play sound effect.

In the present embodiment, target object of reference can be any predefined object such as user's (with " terminal substitutes "), sofa, router, intelligent television.The position of based target object of reference, can analyze the target play sound effect that this target object of reference is corresponding.For Fig. 4, hypothetical target object of reference is the user's (being positioned at the circle centre position of dashed circle) in Fig. 4, then for the position of this user, can determine when reaching target play sound effect, L channel audio amplifier should be positioned at direction, 45 °, this user left front as much as possible, R channel audio amplifier should be positioned at direction, 45 °, user right front as much as possible, and more near better with the distance of this user.

2) according to the position of available audio amplifier, the play sound effect of the often kind of loudspeaker box combination formed between each available audio amplifier is obtained; Export audio options interface, audio options interface comprises the play sound effect of the often kind of loudspeaker box combination formed between each available audio amplifier; Select operation in response to the audio received for audio options interface, selected by audio the play sound effect of operation instruction to be defined as target play sound effect.

In the present embodiment, for all available audio amplifier got, there is various different loudspeaker box combination between these audio amplifiers, then according to the position of each available audio amplifier, the play sound effect of often kind of loudspeaker box combination can be analyzed, therefrom select required target play sound effect for user.As indicated by figures 5 a-5b, in audio options interface shown in terminal, the audio combination that user can view current existence comprises three kinds, be respectively " audio 1 ", " audio 2 " and " audio 3 ", and user can carry out audition to often kind of audio respectively, to determine the required audio selected, suppose that user have chosen " audio 1 " for target play sound effect herein.

Further, audio options interface can also comprise the positional information of each available audio amplifier.Ratio as shown in Figure 5A, when user have chosen " audio 1 ", the loudspeaker box combination " A+B " being somebody's turn to do " audio 1 " corresponding can be illustrated in audio options interface, such as audio amplifier A wherein and target object of reference (are " I " in figure, i.e. user) between angle be left-leaning 45 °, distance is 1.5m, and the angle between audio amplifier B and target object of reference being Right deviation 42 °, apart from being 1.1m, showing the relative position relation between audio amplifier and target object of reference intuitively.

And in figure 5b, except showing audio amplifier corresponding to target play sound effect that user selected, the available audio amplifier that other are all can also be shown, and the relative position relation between each audio amplifier and target object of reference is shown.Such as in figure 5b, the angle between audio amplifier D and target object of reference is close to 45 °, and distance is between the two less than the distance of audio amplifier A and target object of reference, and thus user probably changes audio amplifier A into audio amplifier D, to obtaining better result of broadcast.

It should be noted that:

When illustrating the positional information of available audio amplifier, virtual schematic diagram used in Fig. 5 A-5B can be adopted, simulate the position relationship between available audio amplifier and target object of reference etc.; Or, also outdoor scene photo can be adopted, this outdoor scene photo can carry out gathering and processing obtaining for the first-class equipment of intelligent camera in region residing for terminal or audio amplifier, then user can drag this outdoor scene photo, the operation such as convergent-divergent, walk in region residing for audio amplifier (such as in certain room) seemingly, contribute to the experience promoting user.

In step 308, analyzing the play sound effect that each loudspeaker box combination of available audio amplifier is corresponding, when meeting target play sound effect, proceeding to step 310.

In the step 310, in the loudspeaker box combination meeting target play sound effect, determine L channel audio amplifier and R channel audio amplifier.

For Fig. 4.Hypothetical target object of reference is user self, the terminal of then being carried by user is detected the available audio amplifier in preset range, the border circular areas that this preset range can be is the center of circle with user, predeterminable range R is radius, the audio amplifier A shown in Fig. 4, audio amplifier B, audio amplifier C and audio amplifier D then can be detected, and audio amplifier E cannot be detected because of hypertelorism.

So, the position of based target object of reference, can determine that target play sound effect is mentioned above: L channel audio amplifier should be positioned at direction, 45 °, this user left front as much as possible, R channel audio amplifier should be positioned at direction, 45 °, user right front as much as possible, and more near better with the distance of this user.

Therefore, as shown in Figure 4: audio amplifier A is the most close with " direction, 45 °, user left front ", and audio amplifier D is than the angle of audio amplifier A is large but distance is near, audio amplifier B is the most close with " direction, 45 °, user right front " simultaneously, so loudspeaker box combination " A+B " and loudspeaker box combination " D+B " all may meet target play sound effect.Now, a loudspeaker box combination can be chosen arbitrarily, such that audio amplifier B is R channel audio amplifier, audio amplifier A or audio amplifier D is L channel audio amplifier; Or, can determine that audio amplifier B is R channel audio amplifier, and according to the respective weights of " angle " and " distance " that preset, calculate comprehensive grading corresponding to audio amplifier A and audio amplifier D respectively, thus determine that choosing audio amplifier A or audio amplifier D is L channel audio amplifier further.

For Fig. 5 A-5B.User is by checking all audios shown in audio options interface, and can by the audition to often kind of audio, choose certain target play sound effect, the loudspeaker box combination that then this target play sound effect is corresponding, namely be considered to meet target play sound effect, such as audio amplifier A as L channel audio amplifier, audio amplifier B as the loudspeaker box combination of R channel audio amplifier.In fact, when user is selected by audio options interface, only need to be concerned about interested audio, and without the need to considering the audio amplifier that often kind of audio is corresponding, namely audio amplifier can be " transparent " for user.

Execution mode two: based target position

As another illustrative embodiments, based on the target location determined, L channel audio amplifier and R channel audio amplifier can be chosen, and form corresponding loudspeaker box combination, realize played in stereo.

Wherein, target location can for meeting the position of predefine condition.For example, target location can be the present position of playback equipment, and such as playback equipment can be television set, then target location can be the both sides of television set; Or target location can be user-defined optional position, such as user defines that a target location is sofa left front, parlor, another target location is sofa right front, parlor.

Correspondingly, by obtaining the position of available audio amplifier, situation can be met according to available audio amplifier to target location, choosing the available audio amplifier meeting target location, as L channel audio amplifier and R channel audio amplifier.

Embodiment two: play attribute based on audio frequency

Fig. 6 is a kind of flow chart choosing loudspeaker box combination based on audio frequency broadcasting attribute according to an exemplary embodiment, and as shown in Figure 6, the method can comprise the following steps:

In step 602, all available audio amplifiers are obtained.

In step 604, the audio frequency obtaining the available audio amplifier of every platform plays attribute.

In the present embodiment, the audio frequency of available audio amplifier play attribute can comprise following one of at least: frequency characteristic, signal to noise ratio, dynamic range, transient response etc., the disclosure does not limit this.Audio frequency based on the available audio amplifier of every platform plays attribute, more adequately can analyze the actual play effect of available audio amplifier.

In the present embodiment, propose with " audio frequency of available audio amplifier plays attribute " as condition, determining the technical scheme of L channel audio amplifier and R channel audio amplifier, there is multiple feasible execution mode in this technical scheme, is illustrated below to wherein several execution mode.

Execution mode one: based target play sound effect

As an illustrative embodiments, the target play sound effect of audio frequency to be played can be obtained; Audio frequency according to available audio amplifier plays attribute, obtains L channel audio amplifier and R channel audio amplifier that play sound effect is target play sound effect in available audio amplifier.

In the present embodiment, with the step 306 shown in Fig. 3 analogously, can determine target play sound effect in several ways, the disclosure does not limit this.For example:

1) position of target object of reference can be obtained; According to the position of target object of reference, determine target play sound effect.Ratio as shown in Figure 4, hypothetical target object of reference is the user's (being positioned at the circle centre position of dashed circle) in Fig. 4, then for the position of this user, can determine when reaching target play sound effect, L channel audio amplifier should be positioned at direction, 45 °, this user left front as much as possible, R channel audio amplifier should be positioned at direction, 45 °, user right front as much as possible, and more near better with the distance of this user.

2) attribute can be play according to the audio frequency of available audio amplifier, obtain the play sound effect of the often kind of loudspeaker box combination formed between each available audio amplifier; Export audio options interface, audio options interface comprises the play sound effect of the often kind of loudspeaker box combination formed between each available audio amplifier; Select operation in response to the audio received for audio options interface, selected by audio the play sound effect of operation instruction to be defined as target play sound effect.Such as can pass through the audio options interface shown in Fig. 5 A-5B, choose target play sound effect by user.

Execution mode two: based on best play sound effect

As another illustrative embodiments, attribute can be play according to the audio frequency of available audio amplifier, in available audio amplifier, obtain the loudspeaker box combination of play sound effect the best, using as L channel audio amplifier and R channel audio amplifier.

In the present embodiment, based on the play sound effect of the often kind of loudspeaker box combination formed between each available audio amplifier and correspondence thereof, can by play sound effect corresponding to each loudspeaker box combination of terminal automatic comparison, thus automatically choose the loudspeaker box combination of play sound effect the best, and manually participate in without the need to user, improve automation and the intellectuality that process chosen by audio amplifier.

It is to be noted:

Determine in the processing procedure of loudspeaker box combination based on " position of audio amplifier " and " audio amplifier broadcasting attribute " respectively above-mentioned, if result is relevant to the position of target object of reference, then because the change in attitude, position etc. may occur target object of reference in audio frequency playing process, such as this target object of reference is user, and user may turn round in audio frequency playing process, the behavior such as to walk about, thus the broadcasting demand of user to audio amplifier is caused to change.

For example, assuming that user have chosen the audio amplifier A shown in Fig. 4 and audio amplifier B originally, then, when user moves to the lower right corner, become near user by causing audio amplifier A away from user, audio amplifier C and be positioned at the audio amplifier on the left of user.

Again for example, assuming that user is in the diagram towards the direction (i.e. the top of Fig. 4) residing for audio amplifier A and audio amplifier B, back to audio amplifier C, thus choose that audio amplifier A is L channel audio amplifier, to choose audio amplifier B be R channel audio amplifier; And when turning round towards audio amplifier C in the process of user at listening to audio, will the left side that audio amplifier A is changed to the right side of user, audio amplifier B is changed to user be caused.

Therefore, under a kind of mode, after determining the loudspeaker box combination chosen, can no longer close the motion conditions of target centroid object of reference; And under another kind of mode, can detect the position of target object of reference according to predeterminated frequency, and when position changes, the corresponding loudspeaker box combination chosen of adjustment in time, to be adapted to the situation after changing.

Embodiment three: select based on user
