Cinema is as the place showed a film exclusively for spectators, viewing experience and its vision of the movie theater of each cinema
Effect and auditory effect are closely bound up.Existing movie theater can ensure the sound of stereo set 120 to improve the viewing experience of spectators
Sound is consistent with the content shown described in display screen, and improves the audio effect of the display quality and sound effect device that show screen
Equal measures are experienced to improve the viewing of spectators, and the embodiment of the present invention does not make excessive introduction to this part.
User is during carrying out viewing, due to not having staff to carry out management and control at the scene, for example, beginning in film
Before, what is generally shown is all advertisement, and these advertisements are not relevant for for spectators, and presumable spectators can also be in
The process of chat can't generate interest to advertisement, then at this moment if the sound of stereo set 120 is excessive, it can be to spectators
Poor impression is brought, if after film starts projection, if the sound of stereo set 120 is too small, due to again can be with
The approach of feedback, thus the operations such as volume adjustment can not be carried out, if but be equipped with an earphone to each spectators, then at
This requirement then can be very big, so, an embodiment of the present invention provides a kind of audio play control methods.

Applied to above-mentioned control device 110, described method includes following steps：
Step S110：Obtain multiple volume adjustments request of multiple user feedbacks.
In cinema, a volume feedback button can be arranged in the side at each seat, i.e. spectators can be fed back by volume
Button triggers volume adjustment request, and volume feedback button can be that volume turns key down and volume tunes up key, then a volume adjustment
Request can be that multiple volumes turn request down or multiple volumes tune up request.For example, if spectators feel current stereo set 120
Volume is smaller, it is desirable to tune up a bit, then the volume that can be pressed on seat tunes up button, and volume tunes up button and can touch this as a result,
It signals, i.e., volume tunes up request and is sent to control device 110.
Certainly, volume adjustment request can also obtain by other means, for example, user can be set by mobile terminal to middle control
Standby 110 send etc..
Step S120：The quantity of the multiple volume adjustment request of acquisition is counted after preset duration.
If spectators feed back volume adjustment request to control device 110 one by one, control device 110 can not unite
Meter, then can again be counted after preset duration, such as behind ten minutes that film starts, and the volume adjustment request of acquisition is counted
Quantity, request is tuned up for volume and volume turns request down and can carry out quantity statistics respectively.
Step S130：Judge the quantity of the multiple volume adjustment request whether more than a preset value.
For example, tuning up request to the volume of acquisition carries out quantity statistics, if it is 60 to count volume at this time to tune up request such as,
And the seating capacity of movie theater is 100 at this time, it is assumed that in the case of having a full house, then preset value can be set as to 45, at this point, volume tunes up request
Quantity is more than preset value, can perform step S140：The multiple stereo set 120 is carried out pair according to volume adjustment request
The volume that the volume adjustment answered, i.e. control device 110 control multiple stereo sets 120 is tuned up.If on the contrary, counting volume
It is 60 to turn request down, and preset value is set as 45, then it is more than preset value that volume, which turns number of requests down, then control device 110 controls multiple
The volume of stereo set 120 is turned down.
When volume adjustment request is not above preset value, then the current volume size of stereo set 120 is kept, is not adjusted
Section.As a result, when spectators want that the volume of stereo set 120 is tuned up or turned down, volume adjustment can be asked to feed back to
Control device 110, control device 110 count the quantity of volume adjustment request after preset duration, are more than a preset value in quantity
When, corresponding volume adjustment is carried out to stereo set 120, then spectators can feed back oneself to the volume of stereo set 120
Demand completes the volume adjustment to stereo set 120, improves the viewing experience of spectators.
In addition, in order to realize effective adjusting to the volume of stereo set 120, in the multiple sounds for obtaining multiple user feedbacks
After amount adjusts request, before the quantity of the multiple volume adjustment request that acquisition is counted after preset duration, the method
Further include：
The address information at multiple seats is obtained according to the request of the multiple volume adjustment, wherein each volume adjustment request
The address information at a corresponding seat；It obtains the first of the multiple seat according to the address information at the multiple seat and uses and divide
Cloth characteristic information.
Specifically, if volume adjustment request is that spectators are triggered on seat, each volume adjustment request corresponds to
The address information at one seat is sending the address information that can carry the seat when volume adjustment request, thus can be based on sound
Amount adjusts the address information that request obtains seat, is then believed using distribution characteristics according to the first of the multiple seats of address information acquisition
Breath, when the quantity of the multiple volume adjustment request is more than a preset value, first based on the seat uses distribution characteristics
Information and volume adjustment request carry out corresponding volume adjustment to the multiple stereo set 120, to realize basis
Distribution situation of the crowd in movie theater carries out volume adjustment to stereo set 120, and the viewing to improve spectators is experienced.
Volume adjustment button on each seat can correspond to an address information, can be arranged according to the seat number of movie theater
Address information, for example, 11, indicate the volume adjustment request that first row number one seat is sent, it is assumed that control device 110 is receiving
The volume adjustment request that volume adjustment button on to first row 1,2,4,5, No. 9 seats is sent, can in volume adjustment request
Carry address information, you can the address information at corresponding seat is obtained according to volume adjustment request.
Then obtain multiple seats according to the address information at seat first uses distribution characteristics information, such as address information
It is 11,12,13,22,24, it can be seen that the distribution of its seat is close, and the first use distribution characteristics information can be the close of seat
Distributed degrees are obtained according to the address information carried in the request at this time for example, it is that volume tunes up request to obtain volume adjustment request
After obtaining address information, judge that the distribution situation at seat, specific judgment rule can be according to address information：Due to believing in advance address
Breath be encoded to 11,12,13...21, the numbers such as 22, thus can multiple address informations of acquisition be carried out with variance calculating, side
Difference can indicate the dispersion degree at seat, i.e. tightness degree, and a preset value can be stored in control device 110, that is, is being calculated
When the variance of the address information at the seat arrived is more than preset value, indicate that these seats are more dispersed, it is likely that each in movie theater
Spectators at a position experience bad for the volume of stereo set 120, then mutually should can carry out volume tune to stereo set 120
Greatly, if the variance being calculated is less than or equal to the preset value, indicate that these seats compare concentration, it may be for some region
Acoustics is not fine, then only can carry out volume to the stereo set 120 of part and tune up, such as subregional stereo set 120.
Since in order to save the cost of stereo set 120, stereo set 120 can be arranged at different positions in advance,

Stereo set 120 is installed as first position on the wall in domain, second is used as on the wall of the second area of the position rearward of movie theater
Stereo set 120 is installed in position, i.e. the control device 110 has preset first area corresponding with the first position, with institute
State the corresponding second area in the second position, the first area and the second area combine to be constituted as movie theater whole seat
Viewing region.For example, by taking the cinema hall of 6*9 as an example, the 3*9 region corresponding close to first three row of screen is first area,
And the regions 3*9 corresponding to rear three row far from screen are second area.
Can also be using the acquisition methods of distribution characteristics information for first：Determine the address letter at the multiple seat
It ceases in the first distributed intelligence of the first area and the address information at determining the multiple seat in the second area
Second distributed intelligence；Obtain the multiple seat according to first distributed intelligence and second distributed intelligence first uses
Distribution characteristics information；When the quantity of the multiple volume adjustment request is more than a preset value, first based on the seat makes
The sound equipment of at the first position and/or second place is set with distribution characteristics information and volume adjustment request
Standby 120 carry out corresponding volume adjustment.
For example, it is as stated above, by taking the cinema hall of 6*9 as an example, it can be prestored in control device 110 for place
Stereo set 120 at first position can be in corresponding first area seat number be 11-39, for being in the second place
Stereo set 120 can be in corresponding second area seat number be 41-69, as a result, can after the address information for obtaining seat,
Statistics is in the number (i.e. the first distributed intelligence) of corresponding seat number in first area and is in corresponding in second area
The number (i.e. the second distributed intelligence) of seat number, the address information such as obtained include：11,12,33,45,57,61,77, then wherein
First distributed intelligence is 3, and the second distributed intelligence is 4.Institute is obtained according to first distributed intelligence and second distributed intelligence
State multiple seats first uses distribution characteristics information, specifically, may compare the first distributed intelligence and second distributed intelligence
Difference and obtain first use distribution characteristics information, for example, the first distributed intelligence be 19, the second distributed intelligence be 10,
Obtain first is then using distribution characteristics information：The difference of first distributed intelligence and the second distributed intelligence uses distribution as first
Characteristic information, if such as its difference is 9, when pre-set predetermined threshold value is if 5 in control device 110, then its difference is more than
When predetermined threshold value, the size of the first distributed intelligence and the second distributed intelligence is then judged, if the first distributed intelligence is than the second distribution
Information is 9 more, then the volume of the stereo set 120 at first position is in based on volume adjustment requesting adjustment, if the first distribution
Information is 9 more than the second distributed intelligence, then the volume based on the stereo set 120 for adjusting the requesting adjustment second place, if its
When difference is less than or equal to predetermined threshold value, then the sound equipment of at the first position and second place is asked while adjusted based on volume adjustment
