[0003] There are many existing explanation methods. The first method is to distribute headphones to each visitor, and the visitor listens to the explanation of the explainer through the headphones. This method has problems such as inconvenient headphone recycling and low comfort, and is inefficient; the second method is that the explainer carries a loudspeaker to explain, and the sound is directly played out, and the visitors do not need to wear headphones, but when the number of people in the team is large, the visitors in the back row will not be able to hear clearly, and the loudspeaker is relatively bulky, which is inconvenient for the explainer to carry for a long time; the third method is to use a handheld microphone for voice explanation, and the visitors can hear the sound of the pre-installed audio system on site, but the receivers, power amplifiers, speakers, controllers and other devices in the existing explanation system are also wired and the locations are relatively scattered, which is not convenient for installation and maintenance.

However, the present application can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0057] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present application. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0058] With the development of society and the improvement of people's material and cultural level, some activity venues such as museums, exhibition halls and commodity fairs have become the first choice for people to travel. These activity venues usually need to explain the exhibits to visitors so that visitors can have a deep understanding and learning. There are many existing explanation methods, such as visitors using headphones to listen to the explanation of the explainer, the explainer using an external loudspeaker to explain, and the explanation method of handheld explainers combined with pre-installed loudspeakers. However, these existing explanation methods have the problems of low efficiency, poor user experience and comfort, inconvenient installation and maintenance, and cannot meet the needs of multiple team visits.

[0059] In view of the above problems, this application provides a partition explanation method, as follows Figure 1 As shown, the partition explanation method includes the steps of:

[0060] Step S1: the explanation device sends a location sensing signal;

[0061] Step S2: The zoned sound amplification device determines the real-time status of the explanation device based on the position sensing signal;

[0062] Step S3: The explanation device sends out an audio signal, the zoned sound amplification device receives the audio signal, and based on the real-time status of the explanation device, controls or processes the audio signal according to preset instructions, and controls the output of the played audio.

[0063] It should be noted that the zoned sound amplification equipment is pre-installed in each exhibition hall, and one zoned sound amplification equipment can be set up for each exhibition hall. The explanation equipment can be carried by the explainer, or it can be placed in each exhibition hall, and the explainer can use it when he arrives at the exhibition hall. The played audio can be real-time explanation audio based on the audio signal of the explanation equipment, or it can be background audio pre-stored in the zoned sound amplification equipment, such as light music. Optionally, the explanation equipment can be a microphone or a mobile phone, as long as it can communicate wirelessly with the zoned sound amplification equipment.

[0064] In the present application, a position sensing signal is sent out by the explanation device, and the partitioned sound amplification device determines the real-time status of the explanation device based on the position sensing signal; when the explanation device sends out an audio signal, the partitioned sound amplification device receives the audio signal, and controls or processes the audio signal based on the real-time status of the explanation device, and controls the output of the played audio. In the present application, the partitioned sound amplification device is installed in each exhibition area, and the partitioned sound amplification device communicates with the explanation device wirelessly. The partitioned sound amplification device can process and output the audio signal based on the real-time status of the explanation device, which is more efficient, and provides a higher user experience and comfort, and multiple teams will not interfere with each other when visiting.

[0065] Specifically, for step S1, when the tour guide holds the tour guide device and walks towards the corresponding exhibition area with the visiting group, the tour guide can manually control the tour guide device in advance to make the tour guide device send out a position sensing signal to facilitate communication between the tour guide device and the partition sound amplification device. The position sensing signal sent out by the above-mentioned tour guide device can be an infrared light sensing signal, an RFID sensing signal, a Bluetooth signal, an UWB signal, a radar signal, an ultrasonic signal, or the position sensing information can be the image information of the tour guide device, etc. As long as wireless communication between the tour guide device and the partition sound amplification device can be achieved, the wireless communication method facilitates the movement of the tour guide.

[0066] Optionally, in some embodiments, a two-way authentication mechanism, such as an SSL two-way authentication mechanism, is established between the lecture device and the zoned sound amplification device to prevent interference caused by unauthorized devices.

[0067] Specifically, for step S2, the zoned sound amplification device determines the real-time status of the explanation device based on the position sensing signal.

[0068] Among them, when the position sensing signal is an infrared light sensing signal, an RFID sensing signal, a Bluetooth signal, an ultrasonic signal, or the position sensing signal can be the image information of the explanation device, the partitioned sound amplification device can judge the relative position relationship between the explanation device and the explanation device according to the strength of the position sensing signal. When the position sensing signal is continuously strengthened, it indicates that the explanation device is gradually approaching the partitioned sound amplification device. At this time, the explainer holding the explanation device is following the visiting team to the exhibition area corresponding to the partitioned sound amplification device. When the position sensing signal is continuously weakened, it indicates that the explanation device is gradually moving away from the partitioned sound amplification device. At this time, the visiting team may have completed the visit to the exhibition area and is preparing to go to the next adjacent exhibition area; when the position sensing signal is a UWB signal or a radar signal, the explanation device can be directly located to obtain the real-time status of the explanation device; when the position sensing signal is the image information of the explanation device, the real-time status of the explanation device can be obtained through image recognition.

[0069] In some embodiments, Figure 3As shown, the partitioned sound amplification device determines the real-time status of the explanation device based on the position sensing signal and further includes:

[0070] Step S21: Preset a first perimeter boundary line and a second perimeter boundary line, wherein the first perimeter boundary line is the perimeter boundary line of the exhibition area, and the second perimeter boundary line is formed by expanding outwards by a preset distance on the basis of the first perimeter boundary line; the area enclosed by the first perimeter boundary line is the first perimeter area, and the area between the first perimeter boundary line and the second perimeter boundary line is the second perimeter area;

[0071] Step S22: When the explanation device is located in the first perimeter area, the zoned sound amplification device determines that the explanation device is in an arrival state;

[0072] Step S23: When the explanation device is located in the second perimeter area, the zoned sound amplification device determines that the explanation device is in a proximity state;

[0073] Step S24: When the explanation device is located outside the first perimeter area and the second perimeter area, the zoned sound amplification device determines that the explanation device is in a distant state.

[0074] Combine the following Figure 6 To introduce in detail, the perimeter of the first exhibition area 10 is the first perimeter 101, and the second perimeter 102 is formed by expanding outward at a preset distance on the basis of the first perimeter 101. The preset distance can be adjusted as needed, for example, the preset distance can be 1 meter, 2 meters or 2.5 meters. The area enclosed by the first perimeter 101 is the first perimeter area 103, and the area between the first perimeter 101 and the second perimeter 102 is the second perimeter area 104. When the explanation device is at position P1, it is located outside the first perimeter area 103 and the second perimeter area 104, and the explanation device is in a distant state; when the explanation device is at position P2, it is located in the second perimeter area 104, and the explanation device is in a nearby state; when the explanation device is at position P3, it is located in the first perimeter area 103, and the explanation device is in an arrived state.

[0075] Specifically, for step S3, combined with Figure 4 As shown, the explanation device sends out an audio signal, and the partition sound amplification device processes the audio signal based on the real-time status of the explanation device, and the output of the controlled audio playback also includes:

[0076] Step S31: when the explanation device is in a remote state, the zoned sound amplification device controls or processes the audio signal based on the first preset instruction, and controls the output of the played audio;

[0077] Step S32: When the explanation device is in the proximity state, the zoned sound amplification device controls or processes the audio signal based on the second preset instruction, and controls the output of the played audio;

[0078] Step S33: When the explanation device is in the arrival state, the zone sound amplification device controls or processes the audio signal based on the third preset instruction, and controls the output of the played audio.

[0079] It should be noted that the first preset instruction, the second preset instruction and the third preset instruction are pre-set in the zone sound amplification device.

[0080] In some embodiments, the played audio includes background audio pre-stored in the zoned sound amplification device and real-time explanation audio based on the audio signal of the explanation device;

[0081] The first preset instruction may be: the zoned sound amplification device remains silent or the zoned sound amplification device only plays background audio, etc.;

[0082] The second preset instruction may be: lowering or turning off the background audio, and directly playing the real-time explanation audio according to the preset normal volume, or gradually increasing the volume of the real-time explanation audio from the mute state to the preset normal volume.

[0083] The third preset instruction may be: only play the real-time explanation audio or lower the volume of the background audio while playing the real-time explanation audio.

[0084] In some embodiments, the first preset instruction is only to play background audio;

[0085] The second preset instruction is to reduce the volume of the background audio, and the volume of the real-time explanation audio is gradually increased from a mute state to a preset normal volume, and the preset normal volume can be pre-set in the zoned sound amplification device;

[0086] The third preset instruction is to play the real-time explanation audio only at a preset normal volume.

[0087] Combination Figure 6As shown, when the explanation device is at position P1, the explanation device is far away from the exhibition area 10, and the explanation device is in a distant state. The partition sound amplification device processes the audio signal according to the first preset instruction and controls the output of the played audio, that is, the partition sound amplification device only plays the background audio at this time, and does not play the real-time explanation audio; when the explanation device is at position P2, the explanation device is already located near the exhibition area 10, and the explanation device is in a neighboring state. At this time, the partition sound amplification device processes the audio signal according to the second preset instruction and controls the output of the played audio, that is, reduces the volume of the background audio, and gradually increases the volume of the real-time explanation audio from the mute state to the preset normal volume; when the explanation device is at position P3, the explanation device has arrived at the exhibition area 10, and the explanation device is in an arrived state. The partition sound amplification device controls or processes the audio signal according to the third preset instruction and controls the output of the played audio, that is, the partition sound amplification device only plays the real-time explanation audio at the preset normal volume, and does not play the background audio. When the explanation device moves between multiple exhibition areas, the audio signal of the explanation device can fade in and out between the exhibition areas without interruption, achieving seamless connection, with the sound starting when people arrive and stopping when people leave. Moreover, the audio signal of the explanation device is output in two adjacent exhibition areas at most. When multiple teams visit different areas, they will not be affected by each other, meeting the needs of multiple teams visiting.

[0088] When the tour group visits on their own, in some embodiments, such as Figure 2 As shown, the partition explanation method also includes:

[0089] Step S4: The zoned sound amplification equipment detects human body information in the exhibition area in real time;

[0090] Step S5: The zoned sound amplification device controls the actions of multiple types of auxiliary explanation devices based on human body information.

[0091] Among them, the detection method of the partition sound amplification equipment can be infrared detection, ultrasonic detection or image recognition, etc., and the various types of auxiliary explanation equipment can be lighting, multimedia equipment or air conditioning, etc. The partition sound amplification equipment controls the actions of various types of auxiliary explanation equipment based on human body information, such as lighting brightens when people enter or dims when people leave, and air conditioning turns on when people enter or turns off when people leave, etc., so as to reduce energy consumption while ensuring the comfort and experience of the visiting team during the visit.

[0092] Specifically, for step S4 and step S5, in some embodiments, Figure 5 As shown, the human body information includes the moving speed and moving direction of the visitors in the exhibition hall.

[0093] The zoned sound amplification device controls the actions of various types of auxiliary explanation devices based on human body information, including:

[0094] Step S510: the zoned sound amplification device predicts the movement trajectory of the visitor based on the movement direction of the visitor, and estimates the arrival time of the visitor to the next exhibition area along the movement trajectory based on the movement speed;

[0095] Step S520: The zoned sound amplification device communicates with the zoned sound amplification device of the next exhibition area in advance based on the arrival time, and the zoned sound amplification device of the next exhibition area controls the corresponding multi-type auxiliary explanation devices to start.

[0096] When a visitor is in a certain exhibition area, the zoned explanation equipment corresponding to the exhibition area detects the visitor's moving speed and direction, predicts the visitor's moving trajectory based on the visitor's moving direction, and estimates the visitor's arrival time at the next adjacent exhibition area based on the visitor's moving speed. This enables the control of multiple types of auxiliary explanation equipment in the next exhibition area before the visitor arrives at the next exhibition area, such as turning on lights or air conditioning in advance, to improve the comfort and experience of the visit.

[0097] Based on the same inventive concept, the present application also provides a partition explanation system, such as Figure 7 As shown, it includes an explanation device 1 and a zoned sound amplification device 2. The explanation device 1 is used to send out position sensing signals and audio signals, and to communicate wirelessly with the zoned sound amplification device 2. The zoned sound amplification device 2 is used to receive the position sensing signals and control the output of the played audio based on the position sensing signals.

[0098] Specifically, in some embodiments, the partition sound amplification device 2 includes: a partition sensing module 21, a partition control module 22, an audio receiving module 23, an audio power amplification module 24 and a playback module 25;

[0099] The partition sensing module 21 is used to receive the position sensing signal of the explanation device 1 and perform wireless communication with the explanation device 1. The position sensing signal may be an infrared light sensing signal, an RFID sensing signal, a Bluetooth signal, a UWB signal, a radar signal, an ultrasonic signal, or the position sensing signal may be image information of the explanation device, etc.;

[0100] The partition control module 22 includes a computing unit such as an MCU or a CPU, which is used to determine the real-time state of the explanation device 1 based on the real-time position, and control the output of the playback audio based on the real-time state;

[0101] The audio receiving module 23 is used to receive the audio signal of the explanation device 1 and transmit the audio signal to the audio power amplifying module 24;

[0102] The audio power amplification module 24 is used to amplify the audio signal transmitted from the audio receiving module 23, and transmit the amplified audio signal to the playback module 25;

[0103] The playing module 25 is used to play the audio signal transmitted from the audio power amplifying module 24 .

[0104] The explanation device 1 sends out a position sensing signal, and the partition sound amplification device 2 determines the real-time status of the explanation device 1 based on the position sensing signal; when the explanation device 1 sends out an audio signal, the partition sound amplification device 2 receives the audio signal, and based on the real-time status of the explanation device 1, controls or processes the audio signal to control the output of the played audio. In the present application, the partition sound amplification device 2 integrates a partition sensing module 21, a partition control module 22, an audio receiving module 23 and an audio power amplification module 24, and the entire partition sound amplification device 2 can be directly installed in each exhibition area without multiple cable connections, which is more convenient during installation and has low requirements on the proficiency of the installer. The partition sound amplification device 2 can process and output the audio signal based on the real-time status of the explanation device 1, which is more efficient, and provides a higher user experience and comfort, and multiple teams will not interfere with each other when visiting.

[0105] In some embodiments, Figure 7 As shown, the partitioned sound amplification device 2 also includes a human body sensing module 26, which is used to detect human body information in the exhibition area and upload the human body information to the partition control module 22. The partition control module 22 controls the actions of multiple types of auxiliary explanation devices based on the human body information. The human body information includes the moving speed and moving direction of visitors in the exhibition hall. The multiple types of auxiliary explanation devices can be lights, multimedia equipment or air conditioners. The partitioned sound amplification device 2 controls the actions of multiple types of auxiliary explanation devices based on the human body information, thereby improving the comfort and experience of the visiting team during the visit.

[0106] In the existing exhibition hall explanation system, the receiver, power amplifier, speaker, controller and other devices of the explanation system are all connected by wires. The connection wires are prone to problems such as connector oxidation, physical damage or electromagnetic interference, which will cause the explanation system to fail to work properly. In addition, the installation locations of the receiver, power amplifier, speaker and controller are relatively scattered, which makes it very inconvenient to install them all on the ceiling, and requires a high level of experience and professionalism from the installation implementers.

[0107] Based on the same inventive concept, the present application also provides a partition sound amplification device, such as Figure 8 As shown, the zone sound amplification device 2 includes a housing 27 , a speaker 28 and a control circuit board 29 . The speaker 28 is installed in the housing 27 , and the control circuit board 29 is arranged inside the housing 27 . The control circuit board 29 is communicatively connected with the speaker 28 .

[0108] Specific, combined Figure 7 and Figure 8As shown, the control circuit board 29 integrates a partition sensing module 21, a partition control module 22, an audio receiving module 23, and an audio power amplifying module 24.

[0109] The partition sensing module 21 is used to receive the position sensing signal of the explanation device 1 and perform wireless communication with the explanation device 1. The position sensing signal may be an infrared light sensing signal, an RFID sensing signal, a Bluetooth signal, a UWB signal, a radar signal, an ultrasonic signal, or the position sensing signal may be image information of the explanation device, etc.;

[0110] The partition control module 22 includes a computing unit such as an MCU or a CPU, which is used to determine the real-time state of the explanation device 1 based on the real-time position, and control the output of the audio based on the real-time state;

[0111] The audio receiving module 23 is used to receive the audio signal of the explanation device 1 and transmit the audio signal to the audio power amplifying module 24;

[0112] The audio power amplifier module 24 is used to amplify the audio signal transmitted from the audio receiving module 23 and transmit the amplified audio signal to the speaker 28;

[0113] The speaker 28 is used to play the audio signal transmitted from the audio power amplification module 24 based on the control signal of the partition control module 22 .

[0114] The control circuit board 29 in the partition sound amplification device 2 integrates the partition sensing module 21, the partition control module 22, the audio receiving module 23, and the audio power amplification module 24. There is no need to use wired cables to connect them during installation. The control circuit board 29 and the speaker 28 are pre-connected during production and manufacturing. The partition sound amplification device 2 can be directly fixed to the ceiling, which requires less experience and expertise from the installation implementation personnel. In addition, the partition sensing module 21 directly communicates wirelessly with the explanation device 1, and there is no problem of reduced sound quality due to cable failure or excessively long cables, and the user experience is also better.
