Preferably, according to each loudspeaker relative to the location information for listening to place, and based on parameter setting rule come really
The step of broadcast time-delay of fixed each loudspeaker includes step S133 and step S134: step S133: according to each loudspeaker phase
For listening to the location information in place, to determine each loudspeaker by sound transmission to the time difference listened at place；Step
S134: determining broadcast time-delay opposite between each loudspeaker according to time difference, so that the sound that each loudspeaker issues
It synchronously arrives at and listens to place.
Firstly, according to each loudspeaker relative to the location information for listening to place, to determine that each loudspeaker passes sound
Cast to the time difference listened at place.
Specifically, being first depending on each loudspeaker and establishing relative to the location information for listening to place includes multiple loudspeaker phases
For listening to the coordinate system of place position relationship；Then, each loudspeaker is calculated separately relative to listening on ground according to the coordinate system
The distance of point；The speed difference propagated in air subsequently, based on each loudspeaker relative to the distance and sound for listening to place
Determine each loudspeaker by sound transmission to the time for listening to needs at place；Finally, being based on each loudspeaker for sound transmission
Determine each loudspeaker by sound transmission to the time difference listened at place respectively to the time needed at place is listened to.
Finally, broadcast time-delay opposite between each loudspeaker is determined according to time difference, so that each loudspeaker is sent out
Place is listened in synchronous sound arrival out.
For example, 4 loudspeakers are respectively loudspeaker A, loudspeaker B, loudspeaker C and loudspeaker D, loudspeaker A, loudspeaker B,
Loudspeaker C and loudspeaker D is respectively 1 meter, 2 meters, 1 meter and 2 meters relative to the distance for listening to place where user；Based on 4
Loudspeaker determines loudspeaker relative to the distance for listening to place and the speed 340M/s that propagates in air of sound where user
A, the time for listening to place needs where sound transmission to user is respectively by loudspeaker B, loudspeaker C and loudspeaker D
2.9ms, 5.9ms, 2.9ms and 5.9ms；Then, place needs will be listened to where sound transmission to user based on 4 loudspeakers
Time determine loudspeaker A, loudspeaker B, loudspeaker C and loudspeaker D by where sound transmission to user listen to place when
Between difference be 3ms；Finally, determining that loudspeaker A, loudspeaker C postpone 3ms relative to loudspeaker B, loudspeaker D according to time difference
Sound is played, so that the sound that 4 loudspeakers issue is there are different distances relative to the place of listening to where user
In the case of synchronously arrive at and listen to place where user.
In another example 3 loudspeakers are respectively loudspeaker A, loudspeaker B and loudspeaker C, loudspeaker A, loudspeaker B and loudspeaking
Device C is in the position on three vertex of equilateral triangle, and is respectively 1 relative to the distance for listening to place where user
Rice, 2 meters and 1 meter；Based on 3 loudspeakers relative to the distance for listening to place and the speed propagated in air of sound where user
340M/s is spent, determines loudspeaker A, loudspeaker B and loudspeaker C by the time for listening to place needs where sound transmission to user
Respectively 2.9ms, 5.9ms and 2.9ms；Then, place needs will be listened to where sound transmission to user based on 3 loudspeakers
Time determine loudspeaker A, loudspeaker C relative to loudspeaker B by the time difference for listening to place where sound transmission to user
Value is 3ms；Finally, determine that loudspeaker A, loudspeaker C play sound relative to loudspeaker B delay 3ms according to time difference, so that
The sound that issues of 3 loudspeakers relative to the place of listening to where user, there are synchronously arrive in the case where different distances
Place is listened to where user.Step S140: set the parameters to adjust the sound of each loudspeaker based on broadcasting, so that each
The synchronous sound that loudspeaker issues, which reaches, listens to place, and is listening to volume having the same at place position.
Specifically, based on the volume and/or broadcast time-delay generation broadcasting control signal for each loudspeaker, with control
The synchronous sound that system adjusts each loudspeaker sending, which reaches, listens to place, and is listening to volume having the same at place position.
It should be noted that there are the more factors for influencing sound result of broadcast, in addition to root when loudspeaker makes a sound
Outside according to sound transmission caused by the difference of sound transmission distance to non-circular stereo sound effect fruit caused by listening at place, by
Encountering the echo caused by barrier returns in sound can also interfere with the effect of sound broadcasting.When above-mentioned interference is greater than preset do
When disturbing threshold value, biggish negative effect can be brought to the audio experience degree of user, since echo is interfered, the sound that loudspeaker issues
Acoustic Wave Propagation to user where there is deformation when listening to place, the sound that user hears can lose original tone color.Therefore,
A kind of technical solution is provided below to weaken the interference that sound encounters the echo caused by barrier returns, is broadcast to improve sound
The overall effect put improves user experience.
It should be noted that a kind of common echo interference is as caused by pectination effect.The sound that loudspeaker issues leads to
It crosses two kinds of approach arrival and listens to place, one is straightline propagation to user, referred to as direct sound wave, another kind is by wall, day
The surface of the barriers such as card, floor carries out one or many reflection arrival and listens to place, referred to as echo.Since echo passes through
The path length crossed listens to that the place time is late therefore poor in communication process generation time, and the time difference is mapped to sound than direct sound wave arrival
Corresponding phase difference can be generated in wave.According to the interference theory of wave, echo and direct sound wave are listening to generation interference effect at place,
To make the frequency response curve of sound wave generate pectination effect.
Pectination effect can make frequency response serious deterioration, it is thus regarded that echo is harmful.Pectination effect mainly due to
The envelope of the different sound of the frequency acoustic or phase of different wave occurs being formed by after synergistic effect containing labyrinth
Sound waveform.
Optionally, sound playing method further includes step S150, step S160 and step S170: step S150: being obtained more
The frequency of the broadcasting sound of a loudspeaker；Step S160: relative to barrier and place is listened to according to frequency and multiple loudspeakers
Location information, to determine echo degree of disturbance corresponding with each loudspeaker；Step S170: if echo degree of disturbance is greater than preset
Interference threshold is then adjusted correspondingly the broadcasting setting parameter of each loudspeaker.
Preferably, the step of broadcasting of each loudspeaker setting parameter being adjusted correspondingly include: according to frequency and
Multiple loudspeakers are relative to barrier and listen to the location information in place, and the broadcasting to determine opposite between each loudspeaker is prolonged
