[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Example 1, please refer to Figure 1 As shown, the sound reinforcement method based on active sound field control described in this embodiment includes the following steps:

[0047] S1. Determine the sound field information and construct a sound field propagation model according to the sound field information;

[0048] S2. Construct a sound field monitoring network corresponding to the sound field propagation model, collect sound field information from the sound field monitoring network and transmit it to the sound field propagation model for demonstration, and obtain demonstration results;

[0049] S3, tracing back the corresponding sound reinforcement equipment in the sound field propagation model according to the demonstration results and adjusting it to obtain an adjustment model;

[0050] S4, collecting the sound field information after the sound reinforcement equipment is adjusted through the sound field monitoring network to continuously adjust the sound reinforcement equipment to stabilize it at the sound field threshold;

[0051] As described in the above steps S1-S4, active sound field control, also known as active sound control, is based on the principle of wave interference, that is, the waves generated by two or more sound sources interfere with each other to form the desired sound field distribution; by accurately controlling the phase and amplitude of the secondary sound source, noise elimination or enhancement can be achieved, which is achieved here by using a phase modulator. However, in a sound field space, in addition to controlling the phase and amplitude of the secondary sound source, it is also necessary to control the loudness and frequency in the sound field space. Since the sound reinforcement equipment affects each other, it is necessary to control the sound reinforcement equipment corresponding to the sound field in the space when performing sound field control. However, it is currently difficult to perform corresponding control according to the sound propagation path of the sound reinforcement equipment during the sound field control process, and it is difficult to achieve accurate control of the sound field. In the present application, the sound field threshold that can be set corresponding to the sound field monitoring point is the expected sound reinforcement information at the position, and the gap information and the corresponding sound field monitoring point are marked on the sound field propagation model as a demonstration result, which can be used for subsequent adjustment based on the gap information and the corresponding sound field monitoring point to trace back to the corresponding sound reinforcement equipment to achieve effective control of the sound field, so that the control of the sound reinforcement information in the sound field is more accurate and effective.

[0052] In one embodiment, the step S1 of determining the sound field information and constructing the sound field propagation model according to the sound field information includes:

[0053] S11, determining scene space structure information and corresponding size information as sound field information;

[0054] S12, performing three-dimensional construction according to the sound field information to obtain a three-dimensional model of the sound field;

[0055] S13, collecting the setting position of the sound reinforcement equipment in the scene space, and constructing the sound reinforcement equipment in the three-dimensional model of the sound field according to the setting position;

[0056] S14, marking a propagation path of the sound reinforcement device in the three-dimensional sound field model according to the sound propagation direction of the sound reinforcement device to obtain a sound field propagation model;

[0057] As described in the above steps S11-S14, the scene spatial structure information and the corresponding size information are determined as the sound field information, wherein the scene spatial structure information is the spatial structure in the sound reinforcement scene, for example, the sound reinforcement environment is a cubic spatial structure, and then after obtaining the corresponding size information, a three-dimensional construction can be performed to obtain a three-dimensional model of the sound field, which can specifically display the sound field usage scene information. The steps for constructing the three-dimensional model of the sound field are: Image-based three-dimensional reconstruction: It integrates computer graphics, computer vision and other technologies, and "reverses" restores the three-dimensional structure of the target scene through two-dimensional images. According to the number of cameras, it can be divided into monocular vision method, binocular vision method and multi-eye vision method. Among them, the Structure From Motion (SFM) method is the main multi-view reconstruction method, which is applied to the three-dimensional reconstruction of disordered image sequences. SFM uses the imaging of the same feature point in space on images of different viewing angles, detects and matches the feature points between image sequences, and uses the optimal matching point set combined with the triangulation method to restore the three-dimensional structure of the scene, and then obtains a three-dimensional model of the sound field; in the sound reinforcement scene space, it is necessary to collect the setting position of the sound reinforcement equipment, so as to facilitate the subsequent adjustment of the sound reinforcement equipment to ensure the stable output of the sound quality, and then the sound reinforcement equipment is constructed in the three-dimensional model of the sound field according to the setting position, which has a good environmental collection and display effect, and can greatly improve the subsequent adjustment of the sound reinforcement equipment in the scene space. Since the setting position of the sound reinforcement equipment will affect the output state of the sound quality, it is necessary to mark the propagation path of the sound reinforcement equipment in the three-dimensional model of the sound field according to the sound propagation direction of the sound reinforcement equipment, and obtain the sound field propagation model. According to the sound field propagation model, the sound propagation path of the sound reinforcement equipment can be obtained, which can better facilitate the subsequent adjustment of the sound reinforcement equipment according to the sound reinforcement information;

[0058] In one embodiment, the corresponding sound field propagation model constructs a sound field monitoring network, collects sound field information from the sound field monitoring network and transmits it to the sound field propagation model for demonstration, and step S2 of obtaining a demonstration result includes:

[0059] S21, determining a plurality of sound field monitoring points at the edge of the sound field propagation model, and configuring corresponding cloud servers corresponding to the plurality of sound field monitoring points;

[0060] S22, connecting adjacent sound field monitoring points to obtain a monitoring network, and connecting corresponding cloud servers to obtain a sound field monitoring network according to the connection relationship between the sound field monitoring points in the monitoring network;

[0061] S23, corresponding acquisition terminals are respectively set in the scene space corresponding to the multiple sound field monitoring points, the multiple acquisition terminals are connected according to the connection relationship between the sound field monitoring points in the monitoring network, and the acquisition terminals are communicated with the cloud servers of the corresponding sound field monitoring points;

[0062] S24, determining the target sound and setting the sound field thresholds corresponding to the multiple sound field monitoring points respectively, playing the target sound through the sound reinforcement equipment, collecting the sound field information through the sound field monitoring network and transmitting it to the sound field propagation model for demonstration, and obtaining the demonstration result;

[0063] As described in the above steps S21-S24, in order to better understand the sound quality in the subsequent sound field space, it is necessary to determine multiple sound field monitoring points at the edge position of the sound field propagation model. The edge position of the sound field propagation model is the contour surface in the sound field three-dimensional model. Multiple sound field monitoring points are selected on the contour surface, and corresponding cloud servers are configured for the multiple sound field monitoring points. The sound field monitoring points here are used to monitor the sound amplification information at the edge position of the sound field space, wherein the sound amplification information includes information such as sound amplification loudness and frequency. The cloud server corresponding to the sound field monitoring point is used to store the sound amplification information collected by the sound field monitoring point and for subsequent connection between adjacent sound field monitoring points. After the adjacent sound field monitoring points are connected, a monitoring network is obtained. The cloud servers are connected through a network protocol. The network protocol is, for example, HTTP (HyperText Transfer Protocol) is a protocol used to transmit data between a Web server and a client. The above setting connection is a virtual setting connection. Then, in the actual scene space, the corresponding acquisition terminal is configured for the sound field monitoring point in the sound field monitoring network. The acquisition terminal here is used to collect sound field information. Then, multiple acquisition terminals are connected according to the connection relationship between the sound field monitoring points in the monitoring network, which is equivalent to communication connection between adjacent acquisition terminals. The acquisition terminal is communicated with the cloud server of the corresponding sound field monitoring point. After the acquisition terminal and the connection of the acquisition terminal are set in the scene space, whether the sound field space meets the requirements can be tested. First, the target sound needs to be determined, and the sound field thresholds corresponding to multiple sound field monitoring points are set. The sound field threshold here is the sound reinforcement parameter range set according to the target sound and the distance of sound propagation as the sound reinforcement information under qualified conditions. Then, the target sound is played through the sound reinforcement equipment, and then the sound reinforcement information of the corresponding position is collected through the acquisition terminal in the actual scene space. The sound field information is collected through the sound field monitoring network and transmitted to the sound field propagation model for demonstration to obtain the demonstration result.

[0064] In one embodiment, the step S24 of collecting sound field information through the sound field monitoring network and transmitting it to the sound field propagation model for demonstration to obtain the demonstration result includes:

[0065] S241, obtaining the influence relationship between the sound reinforcement equipment and the sound field monitoring point according to the sound field propagation model;

[0066] S242, collecting the sound field information of the target sound playback through the collection end and transmitting it to the corresponding cloud server, and comparing the sound field information with the sound field threshold corresponding to the corresponding sound field monitoring point to obtain the gap information;

[0067] S243, marking the gap information and the corresponding sound field monitoring points on the sound field propagation model as a demonstration result;

[0068] As described in the above steps S241-S243, the sound field propagation model is a model of the propagation path of the sound reinforcement equipment displayed in the three-dimensional sound field model. Here, since the sound reinforcement equipment has its own propagation path, the propagation path here is a mainly involved sound reinforcement range. For example, in the sound field space, the sound reinforcement equipment faces a direction, then it is a main propagation path in this direction, and other azimuth ranges are not regarded as a mainly involved sound reinforcement range. Then, the sound reinforcement range involved in the sound reinforcement equipment is matched with the sound field monitoring point to obtain the influence relationship between the sound reinforcement equipment and the sound field monitoring point. In determining the influence relationship between the sound reinforcement equipment and the sound field monitoring point, After the sound relationship is established, the sound field information is displayed through the target sound, and then the sound field information of the target sound is collected through the acquisition end and transmitted to the corresponding cloud server, and the sound field information is compared with the sound field threshold corresponding to the corresponding sound field monitoring point to obtain the gap information. The sound field threshold set at the corresponding sound field monitoring point here is the expected sound reinforcement information at this position, and then the gap information and the corresponding sound field monitoring point are marked on the sound field propagation model as a demonstration result, which can be used to trace back to the corresponding sound reinforcement equipment according to the gap information and the corresponding sound field monitoring point for adjustment, so that the sound field can be effectively controlled, and the control of the sound reinforcement information in the sound field is more accurate and effective.

[0069] In one embodiment, the step S3 of tracing back the corresponding sound reinforcement equipment in the sound field propagation model according to the demonstration result and adjusting it to obtain the adjusted model includes:

[0070] S31, taking the sound field monitoring point with gap information as the abnormal detection point, and tracing the sound reinforcement equipment corresponding to the abnormal detection point as the abnormal equipment based on the influence relationship;

[0071] S32, adjusting the sound amplification of the abnormal device according to the adjustment key until the sound field threshold set at the sound field monitoring point is met, and using the sound field propagation model after the abnormal device is adjusted as the adjustment model;

[0072] As described in the above steps S31 and S32, when there is a gap between the sound reinforcement information collected at the collection end and the corresponding sound field threshold, the sound field monitoring point corresponding to the gap information is used as an abnormal detection point, and the sound reinforcement equipment at the corresponding abnormal detection point can be traced back according to the influence relationship, and the sound reinforcement equipment is used as an abnormal equipment, and then the abnormal equipment is adjusted. The adjustment method is to adjust the sound reinforcement parameters of the sound reinforcement equipment. After the adjustment, the sound emitted by the sound reinforcement equipment can meet the expected sound reinforcement demand when it reaches the abnormal detection point, and the sound reinforcement equipment can be better adjusted according to the expected sound reinforcement demand;

[0073] In one embodiment, the step S32 of adjusting the sound amplification of the abnormal device according to the adjustment key until the sound field threshold set at the sound field monitoring point is met includes:

[0074] S321, setting an adjustment key corresponding to the sound field monitoring point in the sound field propagation model, wherein the adjustment key includes a plurality of adjustment points arranged in sequence, and the plurality of adjustment points respectively represent corresponding adjustment degrees;

[0075] S322, establishing an adjustment channel between the adjustment key and the corresponding sound reinforcement device based on the influence relationship;

[0076] S323, dividing the adjustment channel into multiple adjustment sub-channels according to the number of adjustment points, establishing a corresponding relationship between the adjustment sub-channels and the adjustment points, and connecting them;

[0077] S324, setting an adjustment level bar for the corresponding sound reinforcement equipment, establishing a corresponding relationship between multiple adjustment sub-channels and the adjustment level bar according to the adjustment point and connecting them;

[0078] S325, adjusting the sound amplification of the abnormal equipment according to the adjustment key until the sound field threshold set at the sound field monitoring point is met;

[0079] As described in the above steps S321-S325, an adjustment key is set in the sound field propagation model corresponding to the sound field monitoring point. The adjustment key is a port display of an adjustment range. The sound reinforcement information collected by the acquisition end is compared with the sound field threshold to obtain the gap information, and then the sound reinforcement parameters that need to be adjusted can be obtained according to the gap information. In order to more quickly control the sound reinforcement equipment in the adjusted sound reinforcement parameters, the sound reinforcement parameters that need to be adjusted can be displayed on the adjustment key. Then, according to the number of adjustment parts, there are multiple ones, each representing a different adjustment degree. The adjustment degree here is the adjusted sound reinforcement parameter, which is used as the setting here. On the cloud server corresponding to the sound field propagation model, as a port for multiple adjustment degrees of the corresponding sound field monitoring points, the sound field propagation model and the cloud server are integrated here. The sound field propagation model is the appearance display of the cloud server. Then, an adjustment channel is established between the cloud server and the corresponding sound reinforcement equipment. The adjustment channel here is established based on the influence relationship. The influence relationship is the sound field monitoring point affected by the sound reinforcement equipment on the propagation path. When the sound reinforcement information corresponding to the sound field monitoring point does not meet the sound field threshold, the corresponding sound reinforcement equipment is also adjusted. Therefore, in order to adjust the sound reinforcement equipment more quickly, the adjustment channel is adjusted according to the number of adjustment points. The same number of divisions are used to obtain multiple adjustment sub-channels, and a corresponding relationship between the adjustment sub-channels and the adjustment points is established and connected. After that, an adjustment degree bar needs to be set on the sound reinforcement equipment. According to the adjustment points, a corresponding relationship between multiple adjustment sub-channels and the adjustment degree bars is established and connected. The adjustment degree bar is a command bar for controlling the change of sound reinforcement equipment parameters. According to the adjustment points, a corresponding relationship between multiple adjustment sub-channels and the adjustment degree bars is established and connected. The adjustment points here represent the degree of sound reinforcement parameters that need to be adjusted, so they are corresponding command bars for different sound reinforcement parameters. According to the adjustment key, the abnormal equipment is adjusted for sound reinforcement until the sound field monitoring point is satisfied. The sound field threshold is set, and after the adjustment key is triggered, the command is triggered by adjusting the sub-channel on the adjustment degree bar. Here, the adjustment sub-channel does not serve as the information for transmitting regulation, but only as the trigger of a signal. The adjustment sub-channels are isolated from each other and there is no confusion during the process of triggering the command. The sound reinforcement equipment can be adjusted quickly, thereby ensuring that the information that does not meet the sound field threshold is quickly adjusted when collecting sound field information, greatly improving the response ability to sound field regulation, making the quality of sound field regulation better, reducing the time of bad experience caused by sound field information that does not meet expectations, and making the regulation response more rapid.

[0080] In one embodiment, the step S4 of collecting the adjusted sound field information of the sound reinforcement device through the sound field monitoring network and continuously adjusting the sound reinforcement device to stabilize at the sound field threshold comprises:

[0081] S41, collecting the sound field information after the sound reinforcement equipment is adjusted through the sound field monitoring network, comparing the adjusted sound field information with the corresponding sound field threshold and continuously adjusting the sound reinforcement equipment;

[0082] S42, adjusting the sound reinforcement equipment until the sound reinforcement information at the sound field monitoring point is stabilized at the sound field threshold;

[0083] As described in the above steps S41 and S42, the adjustment of the sound reinforcement equipment is ongoing. The content above step S4 is introduced as a process of one regulation. It is continuously adjusted during the use of the sound reinforcement equipment, which can ensure that the sound reinforcement needs are always met during the playback of the target sound, and can greatly improve the regulation of the sound reinforcement equipment. In the process of continuous regulation, the adjustment key and the adjustment degree bar are still used for rapid regulation, which can quickly adjust the sound reinforcement equipment, thereby ensuring that when collecting sound field information, the information that does not meet the sound field threshold is quickly responded to and adjusted, greatly improving the response ability to the sound field regulation, making the quality of the sound field regulation better, reducing the time of the bad experience caused by the sound field information that does not meet the expectations, and making the regulation response faster.
