[0043] The application will be further described below in combination with the drawings and embodiments.

[0044] Figure 1 A classroom sound system is composed of some embodiments. The classroom sound system includes an interactive large screen 100, a wireless microphone 300, and a plurality of wireless sound boxes 200. The interactive large screen 100 is arranged on a podium, the plurality of wireless sound boxes 200 are arranged on the walls of a classroom, and the wireless microphone 300 is configured at least one. The interactive large screen, the wireless microphone, and the plurality of wireless sound boxes are all configured with a wireless communication module to realize wireless communication among them. Preferably, the wireless microphone 300 is matched with a support 400 and a clip, the support 400 can be placed on a teacher's desk, and the wireless microphone can be placed on the support 400 for use, or the wireless microphone can be worn on the teacher's clothes for use through the clip.

[0045] The auxiliary configuration method of the embodiment is used to assist the installer to quickly complete the configuration of the wireless sound box of the classroom sound system. Optionally, the auxiliary configuration method is specifically executed by the interactive large screen 100.

[0046] Referring to Figure 2 The auxiliary configuration method comprises the following steps:

[0047] Step S1, after receiving the position measurement instruction, output a test sound signal to the sound equipment of the podium, output a classroom simulation diagram containing a plurality of test positions to the display device, obtain the sound intensity of the plurality of test positions, and generate the installation position of the sound box in the classroom simulation diagram according to the radiation radius of the sound box and the obtained sound intensity.

[0048] The installation personnel can click the “position measurement” virtual key on the interactive large screen 100 to issue the position measurement instruction.

[0049] The interactive large screen 100 is preferably used as the sound equipment and the display device of the podium to play the test sound and display the classroom simulation diagram.

[0050] Preferably, the classroom simulation diagram is a top-down plan view. Before use, the staff inputs the length and width data of the classroom through the interactive large screen 100, and preferably also inputs the width and length data of the podium, and the interactive large screen automatically generates the classroom simulation diagram and the plurality of test positions according to the input data.

[0051] Preferably, the plurality of test positions are formed by a plurality of horizontal lines and a plurality of vertical lines equally dividing the student area. More preferably, the plurality of test positions are a nine-square grid, i.e., the student area is divided into nine rectangular areas of equal area, each rectangular area being a test position, and preferably the center of the rectangular area is the test position. Figure 3 Fig. 2 schematically shows a classroom simulation diagram containing a plurality of test positions, wherein the numbers 1-9 represent nine test positions.

[0052] Preferably, a wireless microphone matched with the classroom sound system is used as the test sound collection and feedback device.

[0053] Specifically, the step S1 of outputting the classroom simulation diagram containing a plurality of test positions to the display device and obtaining the sound intensity of the plurality of test positions comprises:

[0054] Mark one of the test positions in the classroom simulation diagram as the current test position, and wait for the feedback signal of the wireless microphone;

[0055] Optionally, a specific color or brightness is used to mark in the classroom simulation diagram to guide the installer to the corresponding position. After the installer carries the wireless microphone 300 to the current test position, presses the control button on the wireless microphone 300, the wireless microphone 300 starts to collect the test sound, and ends after a period of time. Optionally, the collection time is controlled by the installer, and the collection start and collection end are controlled by pressing the button on the wireless microphone 300, or the collection time is controlled by the program, and the collection time is preset in the program, for example, 5 seconds. After the collection is completed, the wireless microphone 300 will feed back the collected sound to the interactive large screen 100 after analog-to-digital conversion and other processing;

[0056] When the feedback signal of the wireless microphone is received, the wireless audio signal is extracted from the feedback signal, and the sound intensity of the current test position is formed by processing the wireless audio signal. Specifically, the amplitude of the wireless audio signal can be extracted as the sound intensity;

[0057] According to the above method, the test positions in 1-9 in the classroom simulation diagram are processed respectively to obtain the sound intensity of the test positions. Figure 3

[0058] Specifically, the installation position of the sound box in the classroom simulation diagram in step S1 is generated according to the radiation radius of the sound box and the obtained sound intensity, which includes:

[0059] Determine the test position whose sound intensity does not meet the standard. Specifically, the sound intensity extracted as described above can be compared with the standard value. When it is less than the set interval, it is determined that the sound intensity of the current test position does not meet the standard. Since the test sound in step S1 comes from the podium position, the closer to the podium, the greater the sound intensity, and the farther away from the podium, the smaller the sound intensity;

[0060] Mark all test positions whose sound intensity does not meet the standard on the classroom simulation diagram to form a to-be-enhanced area, Figure 4 The to-be-enhanced area is schematically represented by a dashed line in the classroom simulation diagram;

[0061] Obtain the radiation radius of the sound box. The radiation radius of the sound box is related to its power. The greater the power, the greater the radius of the sound that can be radiated, and the radiation radius can be obtained through the parameters of the sound box or through testing;

[0062] Mark the installation position on the edge line of the to-be-enhanced area according to the radiation radius of the sound box to form a simulation diagram of the sound box installation position. Preferably, the radiation areas of two adjacent sound boxes have partial overlap. The radiation radius of the sound box is preferably not selected as the radius of the sound that can be radiated at the maximum volume of the sound box.

[0063] ​The installer can quickly locate and install the wireless sound box 200 according to the generated simulation diagram of the sound box installation position. After installation, step S2 is performed.

[0064] Step S2, after receiving the equalization adjustment instruction, control each sound box to play a test sound, and again acquire the sound intensity of the plurality of test positions, filter out the test positions with unbalanced sound intensity, and send a fine adjustment instruction to make the corresponding sound box produce fine adjustment until the sound intensity is balanced.

[0065] The installer can click the "equalization adjustment" virtual key on the interactive large screen 100 to issue an equalization adjustment instruction.

[0066] After receiving the equalization adjustment instruction, the interactive large screen 100 sends a set of digital signals to each wireless sound box 200, and each wireless sound box plays a test sound at the same time after receiving the set of digital signals. Optionally, the test sound signal can be built into the wireless sound box 200, or can be included in the set of digital signals and transmitted to the wireless sound box 200 by the interactive large screen 100.

[0067] Specifically, the control of each sound box to play a test sound in step S2, and the acquisition of the sound intensity of the plurality of test positions again, comprises:

[0068] Mark one of the test positions in the classroom simulation diagram as the current test position, and wait for the feedback signal of the wireless microphone;

[0069] Optionally, a specific color or brightness is used for marking in the classroom simulation diagram to guide the installer to the corresponding position. After the installer carries the wireless microphone 300 to the current test position, presses the control button on the wireless microphone 300, the wireless microphone 300 starts to collect the test sound, and after a period of time, the collection is ended. Optionally, the collection time is controlled by the installer, and the collection start and collection end are controlled by pressing the button on the wireless microphone 300, or the collection time is controlled by the program, and the collection time is preset in the program, for example, 5 seconds. After the collection is ended, the wireless microphone 300 feeds back the collected sound to the interactive large screen 100 through the wireless communication module after analog-to-digital conversion and other processing;

[0070] When the feedback signal of the wireless microphone is received, the wireless audio signal is extracted from the feedback signal, and the sound intensity of the current test position is formed by processing the wireless audio signal. Specifically, the amplitude of the wireless audio signal can be extracted as the sound intensity;

[0071] According to the above method, the sound intensity of the test positions 1-9 in Table 1-9 is processed respectively. Figure 3

[0072] ​The test position with uneven sound intensity refers to a test position where the sound intensity extracted at the test position is obviously smaller than that at other test positions or obviously larger than that at other test positions. An optional algorithm is as follows: the mean value of the sound intensity at each test position is calculated, and then the sound intensity at each test position is compared with the mean value. When the difference is greater than a set interval, it is determined that the sound intensity at the test position is too large, and when the difference is less than the set interval, it is determined that the sound intensity at the test position is too small. Regardless of being too large or too small, it is determined that the sound intensity at the test position is uneven.

[0073] Specifically, the step of screening the test position with uneven sound intensity in step S2 and sending a fine-tuning instruction to make the corresponding sound box produce fine-tuning until the sound intensity is balanced includes:

[0074] selecting a test position with uneven sound intensity as a current test position;

[0075] After sending the fine-tuning instruction to the sound box corresponding to the current test position, the sound box 200 will perform the fine-tuning action according to the instruction. Preferably, the fine-tuning instruction includes the code of the sound box, front-back translation data, rotation angle data, and volume data. The rotation angle data includes data with the X-axis as the rotation center, data with the Y-axis as the rotation center, and data with the Z-axis as the rotation center. The front-back translation data is adjustment data in the front-back direction of the classroom, which can control the sound box to adjust in the front-back direction of the classroom, adjust in the X-axis direction, adjust in the Y-axis direction, adjust in the Z-axis direction, and adjust the volume to realize multi-dimensional adjustment. After the sound box 200 performs the fine-tuning action, a feedback signal is fed back to the interactive large screen 100;

[0076] After receiving the feedback signal of the sound box 200, the sound intensity at the current test position is acquired again to determine whether it is balanced;

[0077] The above steps are repeated until the sound intensity at the current test position is balanced; and

[0078] The above steps are repeated to complete the processing of all test positions with uneven sound intensity.

[0079] After completion, the configuration of the wireless sound box of the classroom sound system is completed.

[0080] After using the above auxiliary configuration method, the installer only needs to hold the wireless microphone 300 to the test position to feed back the signal and install the sound box 200 according to the generated sound box installation position, which greatly simplifies the manual operation and can be installed successfully at one time.
