Description

Technical Field

[0001] The present application belongs to the technical field of microphone sound pickup, and specifically relates to a zone explanation method, device and system. Background Art

[0002] Zoning explanation is a kind of explanation method used in exhibition halls or museums. It mainly realizes multi-directional voice explanation by automatically sensing the movement of the tour guide. The general zoning explanation mainly includes automatic sensing, wireless amplification, area switching and multi-team simultaneous explanation. Zoning explanation can significantly improve the visitor's visiting experience and provide high-quality explanation services.

[0003] The existing partition explanation method is that one microphone communicates with multiple wireless boards of multiple broadcast hosts using the same communication frequency, which means that the entire method only supports the use of a few microphones. Moreover, the communication frequency that the wireless board of each broadcast host can receive from the microphone is fixed and the same. If you want to support multiple microphones with different frequencies for partition explanation, you need multiple broadcast hosts to pick up and amplify the sound, which results in high equipment costs and low flexibility. Summary of the invention

[0004] The present application proposes a zoned explanation method, device and system, which can amplify audio signals of different zones using one host by switching communication frequencies, thereby reducing equipment investment costs and improving the flexibility of zoned explanations.

[0005] A first aspect of the present application provides a partition explanation method, the method comprising:

[0006] According to the positioning signal sent by the first microphone, the current communication frequency is set to the first communication frequency;

[0007] Receiving an audio signal sent by a first microphone via a first communication frequency;

[0008] Integrating the positioning signal and the audio signal to obtain a positioning-audio signal;

[0009] By locating the output channel corresponding to the audio signal, the audio signal is amplified to the partition where the first microphone is located.

[0010] The above scheme first receives the positioning signal emitted by the first microphone to determine the current zone where the first microphone is located, and switches the current communication frequency to the first communication frequency for receiving the audio signal emitted by the first microphone, so that only one host can switch the communication frequency to locate and support the sound pickup and amplification of multiple microphones, thereby reducing the equipment cost of the zoned explanation. Then the positioning signal containing the position information of the first microphone and the corresponding audio signal are integrated to obtain the positioning-audio signal containing the position information of the first microphone. The positioning-audio signal can be used to determine which zone the audio signal should be transmitted to for amplification, so that the audio signal emitted by each microphone can be accurately amplified to the corresponding zone, thereby improving the flexibility of the zoned explanation.

[0011] In a possible implementation method of the first aspect, setting the current communication frequency to the first communication frequency according to the positioning signal sent by the first microphone is specifically:

[0012] Obtaining a first communication frequency of a first microphone according to the positioning signal, and setting a current communication frequency as the first communication frequency;

[0013] When the first microphone enters a new zone, the first microphone will send the first communication frequency.

[0014] The above scheme determines the communication frequency corresponding to the first microphone according to the positioning signal, and then adjusts the communication frequency of the host to be the same as that of the first microphone, so that the host can receive the audio signal emitted by the first microphone, providing data support for the subsequent accurate partition sound amplification of the audio signal. Moreover, whenever the first microphone switches its partition, it will send out the first communication frequency to remind the host to switch the communication frequency, ensuring that the host can always clearly locate the microphone and ensure the continuity of sound amplification.

[0015] In a possible implementation method of the first aspect, the positioning signal and the audio signal are integrated to obtain a positioning-audio signal, specifically:

[0016] When the microphone ID of the audio signal is consistent with the microphone ID of the positioning signal, integrating the positioning signal and the audio signal to obtain a positioning-audio signal including the position information of the first microphone;

[0017] When the microphone ID of the audio signal is inconsistent with the microphone ID of the positioning signal, the audio signal is not amplified.

[0018] The above scheme compares the microphone ID of the audio signal with the microphone ID of the positioning signal to determine the partition position where the audio signal needs to be amplified, and integrates the two signals to obtain a positioning-audio signal containing microphone position information, thereby improving the accuracy of partition amplification.

[0019] In a possible implementation method of the first aspect, the audio signal is amplified to the partition where the first microphone is located by locating an output channel corresponding to the audio signal, specifically:

[0020] Performing sound effect processing on the positioning-audio signal, and determining a corresponding output channel according to the first microphone position information of the positioning-audio signal after the sound effect processing;

[0021] The audio signal is transmitted to the sound reinforcement equipment of the partition where the first microphone is located through the output channel and amplified.

[0022] In a possible implementation method of the first aspect, the method further includes:

[0023] Determine the azimuth of the first microphone according to the positioning signal sent by the first microphone; wherein a corresponding measurement distance can be set according to the azimuth;

[0024] The zone where the first microphone is located is determined according to the azimuth angle and the measurement distance.

[0025] In the above scheme, the positioning signal also includes the azimuth of the first microphone from the host. And the corresponding measurement distance can be set according to the azimuth, so that the partitions of different shapes can be covered by the azimuth and the measurement distance, so that the area of ​​the partition explanation is no longer limited to the set shape, which greatly improves the flexibility of the partition explanation.

[0026] A second aspect of the present application provides a partition explanation device, the device comprising: a communication frequency switching module, an audio signal receiving module, a signal integration module and a partition sound amplification module;

[0027] Wherein, the communication frequency switching module is used to set the current communication frequency to the first communication frequency according to the positioning signal sent by the first microphone;

[0028] The audio signal receiving module is used to receive the audio signal sent by the first microphone through the first communication frequency;

[0032] The communication frequency switching unit is used to obtain the first communication frequency of the first microphone according to the positioning signal, and set the current communication frequency to the first communication frequency; wherein, when the first microphone enters a new partition, the first microphone will send the first communication frequency.

[0033] In a possible implementation of the second aspect, the signal integration module includes: a signal integration unit;

[0034] The signal integration unit is used to integrate the positioning signal and the audio signal to obtain a positioning-audio signal containing the position information of the first microphone when the microphone ID of the audio signal is consistent with the microphone ID of the positioning signal; when the microphone ID of the audio signal is inconsistent with the microphone ID of the positioning signal, not amplifying the audio signal.

[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] It should be understood that the step numbers used in this article are only for the convenience of description and are not intended to limit the order in which the steps are executed.

[0048] First embodiment

[0049] For exhibition areas with a larger scope, there are often multiple different partitions, and each partition requires a tour guide to give explanations. If a tour guide needs a microphone, then when the tour guide moves to give explanations, the microphone needs to move between multiple partitions to complete the partition explanations. However, the communication frequency between the wireless board and the microphone of the existing broadcast host is fixed, and the microphone often needs to be switched to the host of different partitions to achieve the partition explanation. This requires that each partition has a host for sound amplification, resulting in high equipment costs and lack of flexibility. Therefore, the embodiment of the present application is to solve how to use only one host to achieve sound amplification when multiple microphones move between multiple partitions.

[0050] like Figure 1 As shown, Figure 1 A specific flow chart of a partition explanation method is provided for a certain embodiment of the present application. The partition explanation method of this embodiment includes steps S1 to S4, which are described in detail as follows:

[0051] Step S1, setting the current communication frequency to the first communication frequency according to the positioning signal sent by the first microphone.

[0052] In the embodiment of the present application, a partition explanation host is used to pick up and amplify the sound of multiple partitions. The partition explanation host includes an audio wireless receiving module, a processor, a positioning module, an audio processing module and a power amplification module. The microphone for picking up sound includes a sound pickup module and a positioning module.

[0053] Among them, the positioning module is based on UWB positioning technology, which can measure the angle within the partition and measure the positioning range of different distances according to different angles, so that the area of ​​the partition explanation is no longer limited to the set shape, which greatly improves the flexibility of the partition explanation. The UWB technology is a wireless communication technology that can be used for close-range precise indoor positioning. Therefore, when the speaker uses a microphone based on UWB technology to give a lecture, the partition explanation host can determine the area where the speaker is located through the microphone positioning, and then determine the source of the audio signal based on the audio signal received with the same microphone ID, thereby specifying the audio signal to be output to the corresponding area speaker through the power amplifier module for sound amplification.

[0054] The implementation of the embodiment of the present application is based on a partition explanation host, which is responsible for receiving audio signals from multiple microphones in multiple partitions and performing corresponding sound amplification. In order to better demonstrate how a partition explanation host manages multiple partitions, Figure 2 A multi-zone architecture diagram is provided. As shown in the figure, the sound reinforcement range of a zone explanation host is a rectangle, which contains 4 zones, and each zone has a speaker for sound reinforcement. When speaker 1 uses microphone 1 in zone 2, the zone explanation host will reinforce the sound in zone 2 according to its position, and when speaker 2 uses microphone 2 in zone 4, the zone explanation host can also realize the designated sound reinforcement in zone 4 at the same time. Multiple microphones can be used in multiple zones at the same time, and multiple microphones can be located in the same zone and used at the same time. Similarly, Figure 2 On the right is the partition architecture diagram of another partition explanation host. Since one partition explanation host can support multiple microphones for sound amplification in multiple partitions, multiple partition explanation hosts can realize the pickup and sound amplification of dozens or hundreds of microphones in different partitions.

[0055] In addition, the sound amplification range of the partition explanation host is not limited, and it can also be various shapes such as fan-shaped, rectangular, etc.

[0056] When the speaker enters a new zone with the first microphone, the positioning module of the first microphone will send a positioning signal with the first microphone ID and the communication frequency information of the first microphone to the zone explanation host. The zone explanation host determines the first communication frequency corresponding to the first microphone according to the positioning signal and the communication frequency information, and sets the first communication frequency to send and receive audio signals with the first microphone. In this way, when the original zone and the new zone overlap, sound amplification can be performed in the two areas to ensure the continuity of sound amplification.

[0057] In this way, when multiple microphones are used at the same time, each time each microphone enters an area, the positioning module of the microphone transmits its communication frequency to the partition explanation host, allowing the partition explanation host to switch to the corresponding communication frequency, realizing automatic frequency switching of the partition explanation host. When multiple partition explanation hosts are installed in multiple partitions of a large exhibition hall, and a partition explanation host supports multiple communication frequencies, such as the common 2-channel, 4-channel, etc., it can be realized through automatic frequency switching technology that each partition explanation host uses several communication frequencies. Multiple partition explanation hosts can achieve dozens or hundreds of communication frequencies without frequency crosstalk.

[0058] Step S2: receiving an audio signal emitted by a first microphone via a first communication frequency.

[0059] In the embodiment of the present application, when the speaker is giving a lecture, the sound pickup module of the first microphone will pick up the speaker's voice and convert it into an audio signal with a microphone ID to the partition explanation host, and at the same time send a positioning signal with the microphone ID to the partition explanation host.

[0060] Specifically, the speaker's voice is first picked up and converted into an audio signal, and then the microphone ID of the first microphone is added to the audio signal through the processor of the first microphone, and then the audio signal with the microphone ID is sent to the audio wireless receiving module of the partition explanation host for reception through the audio wireless transmitting module 1.

[0061] Figure 3 The working principle diagram of the microphone and the partition explanation host is provided. As shown in the figure, the microphone includes a sound pickup module, a positioning module, a processor and an audio wireless transmission module 1; the partition explanation host includes an audio wireless receiving module, a processor, a positioning module, an audio processing module and a power amplifier module, wherein the power amplifier module is connected to the speaker for sound amplification, and the audio signal needs to pass through the audio processing module and then the power amplifier module for sound amplification.

[0062] Step S3: Integrate the positioning signal and the audio signal to obtain a positioning-audio signal.

[0063] In an embodiment of the present application, after receiving the audio signal and the positioning signal, the audio signal and the positioning signal with the same microphone ID are integrated into a positioning-audio signal with the first microphone position information. Wherein, when the microphone ID of the audio signal is inconsistent with the microphone ID of the positioning signal, the audio signal is not amplified.

[0064] Step S4, amplifying the audio signal to the partition where the first microphone is located by locating the output channel corresponding to the audio signal.

[0065] In the embodiment of the present application, the positioning-audio signal is then sent to the audio processing module for sound effect processing, and then power amplification processing is performed to improve the quality of the audio. After the power amplification is completed, the corresponding output channel is selected according to the first microphone position information of the positioning-audio signal for audio output, and the audio is output to the sound reinforcement equipment of the partition where the first microphone is located for sound reinforcement.

[0066] As an improvement to the above scheme, the azimuth of the first microphone can also be determined according to the positioning signal emitted by the first microphone, and then the corresponding measurement distance can be set according to the azimuth to cover the sound reinforcement range of the partitioned explanation host. For example, the measurement distance set for a 1° azimuth is 10 meters, and the measurement distance set for a 2° azimuth is 11 meters. By analogy, the area in the range of 0° to 90° can be set as area 2, and the area in the range of 90° to 180° can be set as area 4, so that the shape of the sound reinforcement range is not limited, and can be various shapes such as a sector, a rectangle, etc.

[0067] Implementing the embodiments of the present application has the following beneficial effects:

[0068] The embodiment of the present application first receives the positioning signal emitted by the first microphone to determine the partition where the first microphone is currently located, and switches the current communication frequency to the first communication frequency for receiving the audio signal emitted by the first microphone, so that positioning and supporting the sound pickup and amplification of multiple microphones can be achieved by switching the communication frequency through only one host, thereby reducing the equipment cost of the partitioned explanation. Then the positioning signal containing the position information of the first microphone and the corresponding audio signal are integrated to obtain a positioning-audio signal containing the position information of the first microphone. The positioning-audio signal can be used to determine which partition the audio signal should be transmitted to for amplification, so that the audio signal emitted by each microphone can be accurately amplified to the corresponding partition, thereby improving the flexibility of the partitioned explanation.

[0073] When the first microphone leaves the current zone, the first microphone will send the first communication frequency.

[0074] The audio signal receiving module 202 is used to receive an audio signal sent by a first microphone via a first communication frequency.

[0075] In the embodiment of the present application, when the speaker is giving a lecture, the sound pickup module of the first microphone will pick up the speaker's voice and convert it into an audio signal with a microphone ID to the partition explanation host, and at the same time send a positioning signal with the microphone ID to the partition explanation host.

By analogy, the area in the range of 0° to 90° can be set as area 2, and the area in the range of 90° to 180° can be set as area 4, so that the shape of the sound reinforcement range is not restricted, and can be various shapes such as sectors and rectangles.

The UWB technology is a wireless communication technology that can be used for close-range precise indoor positioning. Therefore, when the speaker uses a microphone based on UWB technology to give a lecture, the partition explanation host can determine the area where the speaker is located through the microphone positioning, and then determine the source of the audio signal based on the audio signal received with the same microphone ID, thereby specifying the audio signal to be output to the corresponding area speaker through the power amplifier module for sound amplification.

When multiple partition explanation hosts are installed in multiple partitions of a large exhibition hall, and a partition explanation host supports multiple communication frequencies, such as the common 2-channel, 4-channel, etc., it can be realized through automatic frequency switching technology that each partition explanation host uses several communication frequencies. Multiple partition explanation hosts can achieve dozens or hundreds of communication frequencies without frequency crosstalk.
