[0053] As introduced in the background technology, in the existing solution, the adjustment of the two receiving microphones needs to be done manually to improve the two receiving microphones, which takes a long time and results in low efficiency, and user satisfaction is also poor, so that the adjustment of the receiving microphones takes up a lot of time. In order to solve the problem that in the existing solution, the adjustment of the two receiving microphones needs to be done manually to improve the two receiving microphones, which takes a long time and results in low efficiency, the embodiments of the present application provide a control method, central control device, medium, product and system for a receiving microphone.

[0054] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0055] In the present embodiment, a control method for a radio microphone is provided, which is applied to a central control device of a radio microphone system. The radio microphone system further includes a first radio microphone, a second radio microphone, a first ranging sensor and a second ranging sensor. The first radio microphone and the second radio microphone are installed at two ends of the same wall of a radio recording location. The first ranging sensor is installed at the center of the wall where the first radio microphone and the second radio microphone are located. The second ranging sensor is installed at the center of a wall adjacent to the wall where the first radio microphone and the second radio microphone are located. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0056] Figure 1 FIG. 1 is a flow chart of a control method for a sound pickup microphone provided according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0057] Step S101, when it is determined that there is a speaker in the sound receiving place, the distance of the speaker collected by the first distance measuring sensor and the second distance measuring sensor is obtained in real time to obtain a first distance and a second distance, and a plane coordinate system is constructed based on the wall surface on which the first distance measuring sensor is installed and the wall surface on which the second distance measuring sensor is installed, wherein the origin of the plane coordinate system is the intersection of the wall surface on which the first distance measuring sensor is installed and the wall surface on which the second distance measuring sensor is installed;

[0058] Specifically, Figure 2 As shown, a plane coordinate system is constructed based on the wall equipped with the above-mentioned first ranging sensor (i.e., wall A) and the wall equipped with the above-mentioned second ranging sensor (i.e., wall B), and the intersection of wall A and wall B is regarded as the origin of the plane coordinate system, wall A is the x-axis, and wall B is the y-axis.

[0059] Step S102, determining the coordinate position of the speaker in the plane coordinate system as the target position according to the first distance and the second distance, and determining the first position and the second position as the coordinate positions of the tail end of the first pickup microphone and the tail end of the second pickup microphone in the plane coordinate system respectively;

[0060] Specifically, the right-angled side of the fitted right triangle can be calculated based on the first distance and the second distance, so that the coordinate position of the speaker in the plane coordinate system is calculated as the target position.

[0061] The two microphones are selected with the microphone receiving end as the axis.

[0062] Step S103, compare the horizontal axis coordinate of the first position with the horizontal axis coordinate of the target position, rotate the first microphone counterclockwise or clockwise, compare the horizontal axis coordinate of the second position with the horizontal axis coordinate of the target position, rotate the second microphone counterclockwise or clockwise.

[0063] In the above steps, a plane coordinate system is constructed based on the wall surface equipped with the above-mentioned first distance measuring sensor and the wall surface equipped with the above-mentioned second distance measuring sensor, and the coordinate position of the above-mentioned speaker in the above-mentioned plane coordinate system is determined as the target position according to the above-mentioned first distance and the above-mentioned second distance, so that the coordinates of the speaker can be determined more accurately, and finally the horizontal axis coordinate of the above-mentioned first position is compared with the horizontal axis coordinate of the above-mentioned target position, the above-mentioned first sound receiving microphone is rotated counterclockwise or clockwise, the horizontal axis coordinate of the above-mentioned second position is compared with the horizontal axis coordinate of the above-mentioned target position, and the above-mentioned second sound receiving microphone is rotated counterclockwise or clockwise, so that the microphone receiving end of the sound receiving microphone can be accurately aimed at the speaker to improve the sound receiving quality, thereby solving the problem that the adjustment of the two sound receiving microphones in the existing solution needs to be manually adjusted to improve the sound quality of the two sound receiving microphones, and the time required is long, resulting in low efficiency.

[0064] In one embodiment of the present application, comparing the horizontal axis coordinate of the first position with the horizontal axis coordinate of the target position, rotating the first sound pickup microphone counterclockwise or clockwise, comparing the horizontal axis coordinate of the second position with the horizontal axis coordinate of the target position, and rotating the second sound pickup microphone counterclockwise or clockwise, includes:

[0065] When the horizontal axis coordinate of the first position is smaller than the horizontal axis coordinate of the target position, rotating the first sound receiving microphone clockwise;

[0066] When the horizontal axis coordinate of the first position is greater than the horizontal axis coordinate of the target position, rotating the first sound receiving microphone counterclockwise;

[0067] When the horizontal axis coordinate of the second position is smaller than the horizontal axis coordinate of the target position, rotating the second sound pickup microphone clockwise;

[0068] When the horizontal axis coordinate of the second position is greater than the horizontal axis coordinate of the target position, the second sound pickup microphone is rotated counterclockwise.

[0069] Specifically, Figure 3 As shown, at this time, the horizontal axis (i.e., x-axis) coordinate of microphone A is smaller than the horizontal axis coordinate of the speaker, then rotate microphone A clockwise, and the horizontal axis (i.e., x-axis) coordinate of microphone B is larger than the horizontal axis coordinate of the speaker, then rotate microphone B counterclockwise, so that the microphone receiving ends of the two microphones are aimed at the speaker.

[0070] Similarly, if the horizontal axis (i.e., x-axis) of microphone A is greater than the horizontal axis of the speaker, then rotate microphone A counterclockwise. If the horizontal axis (i.e., x-axis) of microphone B is less than the horizontal axis of the speaker, then rotate microphone B clockwise, so that the microphone receiving ends of the two microphones are aimed at the speaker.

[0071] If the horizontal axis (ie, the x-axis) of the coordinates of microphone A is equal to the horizontal axis coordinates of the speaker, microphone A is not rotated. The same is true for microphone B and will not be described in detail here.

[0072] In one embodiment of the present application, after rotating the first sound receiving microphone counterclockwise or clockwise, the method further includes:

[0073] Acquire the decibel value of the sound emitted by the speaker received by the first sound receiving microphone in real time to obtain a first decibel value;

[0074] After the first sound pickup microphone is rotated clockwise, and the change trend of the first decibel value is from increasing to decreasing, the first sound pickup microphone is rotated counterclockwise by a preset angle and then the first sound pickup microphone is stopped;

[0075] After the first sound pickup microphone is rotated counterclockwise and the first decibel value changes from increasing to decreasing, the first sound pickup microphone is rotated clockwise by the preset angle and then the rotation of the first sound pickup microphone is stopped.

[0076] For example, each adjustment is made with a step size of 5°. After the first sound receiving microphone is rotated clockwise, and the first decibel value changes from increasing to decreasing, it is determined that the microphone receiving end of the first sound receiving microphone is aimed at the speaker. However, as time goes by, the first sound receiving microphone is still rotating. In order to eliminate this error as much as possible, the first sound receiving microphone is rotated counterclockwise by 5° (i.e., the preset angle).

[0077] The same process is performed after the first sound receiving microphone is rotated counterclockwise, which will not be described in detail here.

[0078] In one embodiment of the present application, after rotating the second sound pickup microphone counterclockwise or clockwise, the method further includes:

[0079] Acquire in real time the decibel value of the sound emitted by the speaker received by the second sound receiving microphone to obtain a second decibel value;

[0080] After the second sound pickup microphone is rotated clockwise, and the second decibel value changes from increasing to decreasing, the second sound pickup microphone is rotated counterclockwise by a preset angle and then stopped rotating;

[0081] After the second sound pickup microphone is rotated counterclockwise and the second decibel value changes from increasing to decreasing, the second sound pickup microphone is rotated clockwise by the preset angle and then the rotation of the second sound pickup microphone is stopped.

[0082] Specifically, similar to the first sound receiving microphone, for example, the adjustment step is 5° each time. Then, after the second sound receiving microphone is rotated clockwise, and the change trend of the second decibel value is from increasing to decreasing, it is determined that the microphone receiving end of the second sound receiving microphone is aimed at the speaker. However, as time goes by, the second sound receiving microphone is still rotating. In order to eliminate this error as much as possible, the second sound receiving microphone is rotated counterclockwise by 5° (i.e., the preset angle).

[0083] The same process is performed after rotating the second microphone counterclockwise, which will not be described in detail here.

[0084] In one embodiment of the present application, when it is determined that there are at least two speakers in the sound receiving location, the method further includes:

[0085] Acquire the coordinates of each of the above-mentioned speakers in the above-mentioned plane coordinate system in real time to obtain coordinates of multiple speakers;

[0086] Constructing a target common circle as the minimum common circle of all speaker coordinates in the plane coordinate system, and determining the target circle center coordinates as the coordinates of the center of the target common circle in the plane coordinate system;

[0087] Compare the horizontal axis coordinate of the first position with the horizontal axis coordinate of the target circle center coordinate, rotate the first sound pickup microphone counterclockwise or clockwise, compare the horizontal axis coordinate of the second position with the horizontal axis coordinate of the target circle center coordinate, rotate the second sound pickup microphone counterclockwise or clockwise.

[0088] Specifically, Figure 4 As shown, the coordinates of speaker A and speaker B in the above plane coordinate system are obtained in real time;

[0089] A target common circle is constructed based on the coordinates of the two, and the target center coordinates are determined as the coordinates of the center of the target common circle in the plane coordinate system. Then, by comparing the horizontal axis coordinate of the first position with the horizontal axis coordinate of the target center coordinate, the first sound receiving microphone is rotated counterclockwise or clockwise, and by comparing the horizontal axis coordinate of the second position with the horizontal axis coordinate of the target center coordinate, the second sound receiving microphone is rotated counterclockwise or clockwise.

[0090] When the horizontal axis coordinate of the first position is smaller than the horizontal axis coordinate of the target circle center coordinate, rotating the first sound receiving microphone clockwise;

[0091] When the horizontal axis coordinate of the first position is greater than the horizontal axis coordinate of the target circle center coordinate, rotating the first sound receiving microphone counterclockwise;

[0092] When the horizontal axis coordinate of the second position is smaller than the horizontal axis coordinate of the target circle center coordinate, rotating the second sound pickup microphone clockwise;

[0093] When the horizontal axis coordinate of the second position is greater than the horizontal axis coordinate of the target circle center coordinate, the second sound pickup microphone is rotated counterclockwise.

[0094] like Figure 4 As shown, in the presence of target center A and target center B, a target common circle is constructed, and with the target center as a reference, when the horizontal axis (i.e., x-axis) coordinate of microphone A is smaller than the horizontal axis coordinate of the target center, microphone A is rotated clockwise, and when the horizontal axis (i.e., x-axis) coordinate of microphone B is larger than the horizontal axis coordinate of the target center, microphone B is rotated counterclockwise, so that the microphone receiving ends of the two microphones are aligned with the target center.

[0095] Similarly, if the horizontal axis (i.e., x-axis) of microphone A is greater than the horizontal axis of the target circle center, then rotate microphone A counterclockwise. If the horizontal axis (i.e., x-axis) of microphone B is less than the horizontal axis of the target circle center, then rotate microphone B clockwise, so that the microphone receiving ends of the two microphones are aligned with the target circle center.

[0096] If the horizontal axis (ie, x-axis) of the coordinates of microphone A is equal to the horizontal axis coordinates of the center of the target circle, microphone A is not rotated. The same is true for microphone B and will not be described in detail here.

[0097] When there is a speaker, the two distance measuring sensors may be infrared sensors or distance sensors.

[0098] When there are at least two talkers, the two distance measuring sensors may be infrared sensors.

[0099] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the control method of the radio microphone of the present application will be described in detail below in combination with specific embodiments.

[0100] The present embodiment relates to a specific control method for a radio microphone, which is applied to a central control device of a radio microphone system. The radio microphone system further includes a first radio microphone, a second radio microphone, a first distance measuring sensor and a second distance measuring sensor. The first radio microphone and the second radio microphone are installed at two ends of the same wall of a radio recording location. The first distance measuring sensor is installed at the center of the wall where the first radio microphone and the second radio microphone are located. The second distance measuring sensor is installed at the center of a wall adjacent to the wall where the first radio microphone and the second radio microphone are located. Figure 5 As shown, the following steps are included:

[0101] When it is determined that there is a speaker in the sound receiving place, the distance of the speaker collected by the first distance measuring sensor and the second distance measuring sensor is obtained in real time to obtain the first distance and the second distance, and a plane coordinate system is constructed based on the wall surface equipped with the first distance measuring sensor and the wall surface equipped with the second distance measuring sensor, wherein the origin of the plane coordinate system is the intersection of the wall surface equipped with the first distance measuring sensor and the wall surface equipped with the second distance measuring sensor;

[0102] According to the first distance and the second distance, determine the coordinate position of the speaker in the plane coordinate system as the target position, and determine that the first position and the second position are the coordinate positions of the tail end of the first sound pickup microphone and the tail end of the second sound pickup microphone in the plane coordinate system respectively;
