Cinema theatres are venues dedicated to showing movies for the audience, and the viewing experience of the theatre of each cinema theatre is closely related to its visual effect and auditory effect. In order to improve the viewing experience of audiences, the conventional movie hall can ensure that the sound of sound equipment is consistent with the displayed content of a display screen, and improve the display quality of the display screen and the sound effect of sound effect equipment and other measures to improve the viewing experience of the audiences, and the embodiment of the invention does not introduce the part too much.
In the process of viewing a movie, for example, before a movie is started, advertisements are generally shown, but the advertisements are not concerned by viewers, and some viewers may also be in the process of chatting and do not have interest in the advertisements, at this time, if the sound of the sound equipment is too loud, the viewers may feel bad, if the sound of the sound equipment is too loud after the movie starts to be shown, if the sound of the sound equipment is too loud, operations such as volume adjustment cannot be performed because a feedback path does not exist, but if each viewer is equipped with an earphone, the cost requirement is very high, so the embodiment of the invention provides a sound playing control method.
Referring to fig. 1, fig. 1 is a block diagram of a sound playing control system 100 according to an embodiment of the present invention, where the sound playing control system 100 includes a central control device 12 and a plurality of sound devices 120, and the central control device 12 is connected to the plurality of sound devices 120 and is configured to control the plurality of sound devices 120.
Referring to fig. 2, fig. 2 is a flowchart of a sound playing control method according to an embodiment of the present invention, where the method is applied to the central control device 12, and the method includes the following steps:
step S110: a plurality of volume adjustment requests for a plurality of user feedbacks is obtained.
In a movie theater, a volume feedback key can be arranged beside each seat, namely, a volume feedback key can be used for triggering a volume adjustment request by a viewer, the volume feedback key can be a volume down key and a volume up key, and the volume adjustment request can be a plurality of volume down requests or a plurality of volume up requests. For example, if the viewer feels that the current sound volume of the audio device 120 is small and wants to turn up a little, the volume up key on the seat may be pressed, and thus the volume up key may transmit the trigger signal, i.e., the volume up request, to the center control device 12.
Of course, the volume adjustment request may also be obtained in other manners, for example, the user may send the volume adjustment request to the central control device 12 through the mobile terminal.
Step S120: and counting the number of the obtained volume adjustment requests after a preset time length.
If the audience continuously feeds back the volume adjustment request to the central control device 12, and the central control device 12 cannot perform statistics, the statistics may be performed after a preset time duration, for example, after ten minutes from the beginning of the movie, the number of the obtained volume adjustment requests may be counted, and the number statistics may be performed for the volume up request and the volume down request respectively.
Step S130: and judging whether the number of the volume adjustment requests exceeds a preset value.
For example, the obtained volume up requests are counted, if the volume up request is counted as 60, and the number of seats in the living room is 100, assuming that the seats are full, the preset value may be set as 45, and the volume up request number exceeds the preset value, step S140 may be executed: and performing corresponding volume adjustment on the plurality of audio devices 120 according to the volume adjustment request, that is, the central control device 12 controls the volume of the plurality of audio devices 120 to be increased. On the contrary, if the volume reduction requests are counted as 60 and the preset value is set as 45, the number of volume reduction requests exceeds the preset value, and the central control device 12 controls the volume of the plurality of audio devices 120 to be reduced.
When the volume adjustment request does not exceed the preset value, the current volume of the audio device 120 is maintained and is not adjusted. Therefore, when the audience wants to turn up or turn down the volume of the audio device 120, the volume adjustment request can be fed back to the central control device 12, the central control device 12 counts the number of the volume adjustment requests after the preset time duration, and when the number exceeds a preset value, the corresponding volume adjustment is performed on the audio device 120, so that the audience can feed back the demand of the audience on the volume of the audio device 120 to complete the volume adjustment on the audio device 120, and the audience viewing experience is improved.
In addition, in order to achieve effective adjustment of the volume of the audio device 120, after obtaining a plurality of volume adjustment requests fed back by a plurality of users, before counting the number of the obtained plurality of volume adjustment requests after a preset time period, the method further includes:
obtaining address information of a plurality of seats according to the volume adjustment requests, wherein each volume adjustment request corresponds to the address information of one seat; and acquiring first use distribution characteristic information of the plurality of seats according to the address information of the plurality of seats.
Specifically, if the volume adjustment requests are triggered by the audience on the seats, each volume adjustment request corresponds to address information of one seat, that is, address information of the seat can be carried when the volume adjustment request is sent, so that the address information of the seat can be obtained based on the volume adjustment request, then the first usage distribution characteristic information of a plurality of seats is obtained according to the address information, and when the number of the volume adjustment requests exceeds a preset value, the volume adjustment is correspondingly performed on the plurality of acoustic devices 120 based on the first usage distribution characteristic information of the seat and the volume adjustment request, so that the volume adjustment is performed on the acoustic devices 120 according to the distribution situation of people in the movie hall, and the viewing experience of the audience is improved.
The volume adjustment key on each seat may correspond to one address information, and the address information may be set according to the seat number of the living room, for example, 11, which indicates a volume adjustment request sent by the first row seat, and if the central control device 12 receives a volume adjustment request sent by the volume adjustment keys on the first row seats 1, 2, 4, 5, and 9, the volume adjustment request may carry the address information, that is, the address information of the corresponding seat may be obtained according to the volume adjustment request.
Then, first usage distribution characteristic information of the plurality of seats is obtained according to the address information of the seats, for example, the address information is 11, 12, 13, 22, 24, so that the distribution of the seats is seen to be tight, the first usage distribution characteristic information may be the tight distribution degree of the seats, for example, the obtained volume adjustment request is a volume increase request, at this time, after the address information is obtained according to the address information carried in the request, the distribution situation of the seats is judged according to the address information, and the specific judgment rule may be: since the address information is encoded in advance into numbers 11, 12, 13.. 21, 22, etc., variance calculation can be performed on the obtained multiple pieces of address information, the variance can represent the discrete degree, i.e., the tightness degree, of the seats, a preset value can be stored in the central control device 12, i.e., when the variance of the address information of the calculated seats is greater than the preset value, it represents that the seats are relatively dispersed, and it is likely that the sound volume of the sound device 120 is not well felt by the audience at each position in the studio, the sound volume of the sound device 120 can be correspondingly adjusted to be larger, and when the variance is less than or equal to the preset value, it represents that the seats are relatively concentrated, and the sound effect of a certain area is not good, the sound volume of only part of the sound device 120 can be adjusted to be larger, such as the sound device 120 with partitioned areas.
Since the audio devices 120 can be arranged at different positions in advance in order to save the cost of the audio devices 120, as shown in fig. 3, the audio devices 120 at different positions can be controlled individually, for example, the wall of a first area close to the display screen is used as the first position to install the audio devices 120, and the wall of a second area at a rear position of the studio is used as the second position to install the audio devices 120, i.e., the central control device 12 is preset with a first area corresponding to the first position and a second area corresponding to the second position, and the combination of the first area and the second area is a viewing area formed by all seats of the studio. For example, taking a 6 x 9 cinema as an example, the 3 x 9 area corresponding to the first three rows close to the screen is the first area, and the 3 x 9 area corresponding to the last three rows far away from the screen is the second area.
The method for acquiring the first usage distribution feature information may further include: determining first distribution information of the address information of the plurality of seats in the first area and second distribution information of the address information of the plurality of seats in the second area; obtaining first usage distribution characteristic information of the plurality of seats according to the first distribution information and the second distribution information; when the number of the volume adjustment requests exceeds a preset value, performing corresponding volume adjustment on the audio device 120 at the first location and/or the second location based on the first usage profile information of the seat and the volume adjustment requests.
For example, as described above, in the case of the cinema hall of 6 × 9, the central control device 12 may store in advance seat numbers 11 to 39 in the first area corresponding to the audio device 120 at the first position and seat numbers 41 to 69 in the second area corresponding to the audio device 120 at the second position, so that the number of the seat numbers corresponding to the first area (i.e., the first distribution information) and the number of the seat numbers corresponding to the second area (i.e., the second distribution information) may be counted after obtaining the address information of the seats, and the obtained address information may include: 11. 12, 33, 45, 57, 61, 77, the first distribution information is 3, and the second distribution information is 4. Obtaining first usage distribution characteristic information of the plurality of seats according to the first distribution information and the second distribution information, specifically, comparing the difference between the first distribution information and the second distribution information to obtain first usage distribution characteristic information, for example, the first distribution information is 19, the second distribution information is 10, and the first usage distribution characteristic information is obtained by: a difference between the first distribution information and the second distribution information is used as the first usage distribution characteristic information, for example, if the difference is 9, if a preset threshold preset in the central control device 12 is 5, the difference is greater than the preset threshold, then the sizes of the first distribution information and the second distribution information are determined, if the first distribution information is 9 more than the second distribution information, the volume of the audio device 120 at the first position is adjusted based on the volume adjustment request, if the first distribution information is 9 less than the second distribution information, the volume of the audio device 120 at the second position is adjusted based on the adjustment request, and if the difference is less than or equal to the preset threshold, the volumes of the audio devices 120 at the first position and the second position are adjusted simultaneously based on the volume adjustment request, so that the audio device 120 can be flexibly adjusted as needed.
In addition, it is also possible to obtain the distribution of seats based on the obtained address information, and then adjust the volume of the audio device 120 at the first location and/or the second location according to the distribution of seats. For example, if the distribution of seats is close to the first position, the audio device 120 at the first position may be adjusted based on the volume adjustment request, for example, taking seat numbers 11 to 100 as an example, the central control device 12 may store in advance that the seat numbers 11 to 49 may correspond to the audio device 120 at the first position, and the seat numbers 51 to 100 may correspond to the audio device 120 at the second position, so that after obtaining the address information of the seats, the number of seat numbers corresponding to the first position and the number of seat numbers corresponding to the second position may be counted, for example, the obtained address information includes: 11. 12, 33, 45, 57, 61, 77, and then comparing the number of seat numbers corresponding to the first position with the number of seat numbers corresponding to the second position, if the number of seat numbers corresponding to the first position is greater than the number of seat numbers corresponding to the second position, then the volume of the audio device 120 at the first position is adjusted accordingly, and if the number of seat numbers corresponding to the first position is equal to the number of seat numbers corresponding to the second position, the sound equipment 120 at the first position and the sound equipment 120 at the second position can be adjusted in volume at the same time, if the number of the seat numbers corresponding to the first position is smaller than that of the seat numbers corresponding to the second position, the sound equipment 120 at the second position is adjusted in volume, the volume adjustment of the audio device 120 is based on whether the volume adjustment request is an up or down request, and thus the audio device 120 can be flexibly adjusted as needed.
In addition, in order to avoid that some seats are not used, that is, the seats are not used, and the nearby audience triggers the volume adjustment button on the seat, so that the central control device 12 also receives the volume adjustment request correspondingly sent by the seats, then some spurious information is caused for the subsequent volume adjustment request statistics and the calculation of the first usage profile information is disturbed, so that the obtained first usage profile information is not accurate, it is also possible that after the first usage distribution characteristic information of the plurality of seats is acquired based on the address information of the plurality of seats, when the number of the volume adjustment requests exceeds a preset value, before performing corresponding volume adjustment on the sound devices 120 based on the first usage profile information of the seats and the volume adjustment requests, the method further includes: obtaining the use information of each seat in the photo hall, which is acquired by the information acquisition device 111, wherein the use information of each seat corresponds to the address information of one seat; acquiring address information corresponding to the used seats according to all the acquired use information; acquiring second use distribution characteristic information according to the address information of the used seat; obtaining final usage distribution characteristic information based on the first usage distribution characteristic information and the second usage distribution characteristic information, and then performing corresponding volume adjustment on the plurality of audio devices 120 based on the final usage distribution characteristic information of the seat and the volume adjustment request when the number of the volume adjustment requests exceeds a preset value.
Specifically, referring to fig. 4, the information collecting device 111 is in communication connection with the central control device 12, and the information collecting device 111 is configured to collect usage information of each seat in the living room and send all the collected usage information to the central control device 12, where each usage information corresponds to one address information, that is, the information collecting device 111 also carries address information corresponding to the seat when sending the usage information, so that when the central control device 12 receives all the usage information, the central control device obtains address information corresponding to a used seat according to all the obtained usage information, then obtains second usage distribution characteristic information according to the address information of the used seat, and then obtains final usage distribution characteristic information based on the first usage distribution characteristic information and the second usage distribution characteristic information, when the number of the volume adjustment requests exceeds a preset value, based on the distribution characteristic information of the final use of the seats and the volume adjustment request, the volume adjustment is correspondingly performed on the plurality of sound equipment 120, so that the sound equipment 120 is adjusted in volume according to the distribution situation of people in the movie hall, and the movie watching experience of audiences is improved.
As an embodiment, the information collecting apparatus 111 includes: the system comprises a collecting sensor arranged below each seat in the auditorium and a data collector 112 arranged below any seat in each row of seats in the auditorium, wherein each collecting sensor in each row is connected with the data collector 112 in the row, and each data collector 112 is connected with the central control device 12. For the sake of understanding, the photo hall with 6 × 9 is taken as an example for explanation, and it is assumed that the photo hall has 6 rows of seats, each row has 9 positions, and the number of the above-mentioned acquisition sensors is 54 and the number of the data collectors 112 is 6, where the 9 acquisition sensors in one row are all connected to one data collector 112 in the row, that is, the data collector 112 in each row is responsible for summarizing the usage information of the seat in the row and then sending the summarized usage information to the central control device 12.
It should be noted that the above illustration is only one embodiment of the present embodiment, and it is also possible that a plurality of rows of collecting sensors correspond to one data collector 112, or a plurality of rows of collecting sensors correspond to several data collectors 112, and different setting rules and numbers of data collectors 112 are different, which results in different structures of the information collecting device 111. Furthermore, the above schematic figures, such as the number of seats in the living room, are only examples for illustrating the arrangement of the collecting sensors and the data collector 112, and should not be construed as limiting the present invention.
The acquisition sensor can be a pressure sensor, and can detect whether someone sits down on the seat, namely whether this seat is used, and when someone or nobody are on the seat, the signal of its transmission is different, can judge the in service behavior of this seat according to the signal of difference. The pressure sensor may be a pressure sensor commonly used at present, such as a semiconductor pressure sensor, a strain gauge pressure sensor, a load cell, or the like. The collection sensor may be a compound key switch, for example, which is turned on or off when the seat is occupied, so that the data collector 112 can know whether the seat is occupied according to the signal of the switching device.
When receiving the acquisition information transmitted by the acquisition sensor connected to the data collector 112, each data collector 112 performs address marking on the acquisition information transmitted by the acquisition sensor to obtain usage information, and transmits the usage information to the central control device 12. Each acquisition sensor corresponds to address information, and the address information of each acquisition sensor can be set according to the seat number of the living room, for example, 11, identifies the sensor at the first row of the first seat position, and assumes that the data collector 112 located at the first row carries out address marking on the acquisition information transmitted by the acquisition sensor at the first row of the seat number 1, 2, 4, 5, 9 when receiving the acquisition information transmitted by the acquisition sensor at the first row of the seat number 1, 2, 4, 5, 9, the acquisition information transmitted by the acquisition sensor at the first row of the position 1 is marked with 11 to obtain usage information, and the acquisition information transmitted by the acquisition sensor at the first row of the position 2 is marked with 12 to obtain usage information.
For example, the usage information may be divided into 1 and 0, where 1 indicates that the seat is used, 0 indicates that the seat is not used, if the seat with address information of 11 is used, the usage information may be represented as 1 to 11, and if the seat with address information of 13 is not used, the usage information may be represented as 0 to 13.
It should be noted that the above illustration is only an example of the present embodiment, and the present invention is not limited thereto.
Further, as an alternative embodiment, as shown in fig. 5, each data collector 112 includes a first controller 1121, a wireless transmission module 1122, and an encoder 1123.
