Description

Technical Field

[0001] This invention relates to the field of intelligent signage technology, specifically to a multi-faceted intelligent electronic display signage. Background Technology

[0002] Scenic areas, as important venues for public visits and tours, typically feature various signs to guide visitors, provide information about attractions, and remind them of safety precautions. With the development of intelligent technology, electronic display signs are becoming increasingly common in scenic areas. These signs not only display text and images on electronic screens but also incorporate voice announcements to provide multimodal guided tours. Existing electronic display signs mostly employ single-sided or double-sided structures, using built-in voice modules to provide fixed-volume voice prompts, thereby enhancing the convenience of information access for visitors.

[0003] However, in actual scenic area environments, the voice broadcast function of existing signs has significant shortcomings due to the significant variations in visitor density and on-site noise levels over time and at different locations. On the one hand, when signs are located in areas with high visitor traffic, the ambient noise level is high, and the fixed volume of the voice broadcast may be too low, making it difficult for visitors who need to hear the audio to clearly obtain the information. On the other hand, in relatively quiet areas with dense visitor flow, the fixed volume may be too high, easily causing noise interference, affecting the visitor experience of nearby visitors, and even becoming a source of complaints. Furthermore, existing electronic signs have a limited number of display surfaces and restrict the direction of information display, making it difficult to cater to visitor groups from multiple directions in open spaces within scenic areas, resulting in incomplete information coverage and insufficient visibility.

[0004] Therefore, there is an urgent need for an intelligent electronic display sign that can automatically adjust the voice volume in different environments and has the ability to display information on multiple sides, so as to improve the quality of information services and the tourist experience in scenic areas. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-faceted intelligent electronic display sign to solve the technical problems of existing scenic spot signs, such as the inability to adaptively adjust the volume according to environmental changes and the difficulty in accommodating tourists from multiple directions, thus affecting the tourist experience.

[0006] To achieve this objective, the present invention adopts the following technical solution: A multi-faceted intelligent electronic display signboard includes a display component and a control terminal. The display component includes a housing and a display screen. The housing includes a main housing and side housings, with the side housings rotatably disposed on both sides of the main housing. The display screens are respectively disposed on the main housing and the side housings. The housing contains a camera component, a sound source acquisition component, and a voice adjustment component, all communicatively connected to the control terminal. The camera component is used to collect pedestrian traffic information around the signboard. The sound source acquisition component is used to collect and monitor the sound distribution in the surrounding spatial environment. The voice adjustment component outputs voice. The control terminal adjusts the volume of the voice output from the voice adjustment component based on the pedestrian traffic information and also adjusts the position of the voice output from the voice adjustment component based on the sound distribution.

[0007] Optionally, the voice adjustment component includes a speaker, a sliding member, and a slide rail. The slide rail is disposed inside the housing along the length direction of the housing. The sliding member drives the speaker to slide along the slide rail under the control of the control terminal. The housing is provided with a sound hole, which is disposed directly opposite to the speaker.

[0008] Optionally, a guide plate is provided inside the sound hole. The guide plate, which is located on the left side along the length direction of the outer shell, is positioned in a first position inside the sound hole to transmit the sound source of the speaker to the left side of the outer shell. The guide plate, which is located in the middle along the length direction of the outer shell, is positioned in a second position inside the sound hole to transmit the sound source of the speaker to the front side of the outer shell. The guide plate, which is located on the right side along the length direction of the outer shell, is positioned in a third position inside the sound hole to transmit the sound source of the speaker to the right side of the outer shell.

[0009] Optionally, the guide plate includes a first partition and a second partition, and an opening and closing assembly is also provided in the sound hole.

The second rotating block is provided with a second connecting post, which is inserted into the second limiting groove. The actuator is provided on the guide frame and is used to drive the slider to slide along the guide frame.

[0012] Optionally, the voice adjustment component further includes a conductive track and an electrical contact. The extension direction of the conductive track is the same as the extension direction of the slide rail. The electrical contact is electrically connected to the speaker. The conductive track is provided with a groove along its length. A conductive sheet is provided on the bottom surface of the groove. The conductive sheet is connected to an external power source. The electrical contact slides along the groove and is electrically connected to the conductive sheet.

[0014] Optionally, the sound source acquisition component includes a microphone, and multiple microphones are provided, which are respectively arranged on the housing along the length direction of the housing. They are used to collect the sound from different locations around the sign and transmit the collected information to the control terminal. The control terminal compares the sound from different locations and instructs the sliding member to drive the speaker to slide towards the position with the highest volume.

[0015] Optionally, a filter screen is provided on the outer peripheral surface of the sound hole.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This embodiment of the invention features displays on both the main housing and side housings, enabling the electronic display signage to display information from multiple angles. Simultaneously, by incorporating camera components within the multi-faceted intelligent electronic display signage, real-time data collection of pedestrian traffic around the signage is achieved. The control terminal dynamically adjusts the output volume of the voice adjustment component based on feedback from the camera components, allowing the voice broadcast function to adaptively adjust to changes in pedestrian traffic in the environment. Furthermore, this embodiment uses a sound source acquisition component to detect and collect sound distribution in the surrounding environment in real time, enabling the control terminal to determine the direction of the sound sources from visitors. When visitors inquire or interact with the signage via voice, the control terminal adjusts the output direction of the voice adjustment component based on the sound source location, ensuring more precise targeting of the system's voice feedback to the user, thereby improving the directionality and clarity of the interaction.

[0025] This embodiment provides a multi-sided intelligent electronic display signboard, which can be applied in scenic spots, shopping malls or public places to display information to tourists or people in multiple directions and provide voice prompts and interactions. In this embodiment, by improving the structure of the multi-sided intelligent electronic display signboard, adaptive adjustment of information display in multiple directions and voice output is realized, making the broadcast content clear, the direction accurate and enhancing the interactive experience of tourists.

[0026] Please see Figures 1-10 The multi-faceted intelligent electronic display sign provided in this embodiment includes a display component 10 and a control terminal 20. The display component 10 includes a housing 110 and a display screen 120. The housing 110 includes a main housing 111 and a side housing 112. The side housing 112 is rotatably disposed on both sides of the main housing 111. The display screen 120 is disposed on the main housing 111 and the side housing 112 respectively. The housing 110 is provided with a camera component 30, a sound source acquisition component 40 and a voice adjustment component 50, all of which are communicatively connected to the control terminal 20. The camera component 30 is used to collect pedestrian traffic information around the sign. The sound source acquisition component 40 is used to collect and monitor the sound distribution in the spatial environment around the sign. The voice adjustment component 50 is used to output voice. The control terminal 20 adjusts the voice output volume of the voice adjustment component 50 according to the pedestrian traffic information and also adjusts the voice output position of the voice adjustment component 50 according to the sound distribution.

[0027] Specifically, a display screen 120 is provided on the main housing 111 and the side housing 112 respectively. The display screen 120 can be an existing mature display device such as an LCD screen, an LED display screen 120 or an OLED display screen 120. The sign can display graphic and textual information in multiple directions, expanding the display range of the single-sided sign, so that tourists from different directions can see the displayed content at the first time, and improve the coverage and visibility of public information dissemination.

[0028] The camera component 30 can be a conventional high-definition camera, infrared camera, or depth camera, all of which are existing mature image acquisition devices capable of collecting pedestrian traffic information around the sign. The sound source acquisition component 40 can be a microphone array, directional microphone, or other sound acquisition devices capable of monitoring and locating the sound distribution in the spatial environment. Both the camera component 30 and the sound source acquisition component 40 described in this embodiment can be selected according to the actual installation environment. Their hardware structures are existing mature solutions that can be easily understood by those skilled in the art; therefore, this specification does not elaborate on the specific circuit structure.

[0029] The voice adjustment component 50 is used to output voice commands from the control terminal 20. It can employ devices such as a conventional speaker 510, a directional sound field speaker 510, or a variable directivity sound source device to achieve controllable volume and propagation direction. In this embodiment, the pedestrian flow information acquired by the camera component 30 is analyzed in real time by the control terminal 20, and the volume of the voice adjustment component 50 is automatically adjusted according to the pedestrian density. For example, in scenic area entrances, squares, or key areas with high pedestrian flow, the control terminal 20 can appropriately increase the volume of the voice broadcast to ensure that tourists can clearly receive the broadcast content even in noisy environments; in areas with low pedestrian flow, the volume is automatically reduced to avoid noise interference caused by continuous high-volume playback, thus maintaining a suitable sound output level in different environments, improving information transmission efficiency, and improving the sound environment of public spaces.

[0030] Meanwhile, the sound source acquisition component 40 continuously monitors the sound distribution around the electronic display sign and identifies the location of tourists using a spatial sound source localization algorithm. When tourists ask for directions or engage in other voice interactions, the control terminal 20 adjusts the direction of the voice adjustment component 50 based on the sound source location, concentrating the voice feedback towards the tourist's location. This improves the targeting and clarity of the voice interaction, enhances the interactive experience of the sign, reduces sound interference to unrelated tourists, and improves the overall user experience.

[0031] Furthermore, the voice adjustment component 50 includes a speaker 510, a sliding member 520, and a slide rail 530. The slide rail 530 is disposed within the housing 110 along its length. Under the control of the control terminal 20, the sliding member 520 drives the speaker 510 to slide along the slide rail 530. The housing 110 is provided with a sound hole 101, which is directly opposite to the speaker 510. Specifically, the slide rail 530 can be a conventional sliding mechanism such as a metal slide rail 530, a plastic slide groove 541, or a linear guide rail with a ball bearing structure. These structures are all mature mechanical components well known to those skilled in the art and can ensure the smooth movement of the sliding member 520 on the slide rail 530. The sliding member 520 can be a stepper motor push rod structure, a lead screw slider 722 structure, or a rack and pinion structure, etc. Its function is to realize the controllable position adjustment of the speaker 510 inside the housing 110, so that the speaker 510 can switch positions according to the sound source direction information fed back by the sound source acquisition component 40.

[0032] The loudspeaker 510 is used to output voice content. It can be a conventional full-range loudspeaker 510, a directional loudspeaker 510, or a narrow-angle beam loudspeaker 510, etc., as the sound source output device. The specific model and specifications can be selected according to actual application requirements. It is a mature existing acoustic device. The sound hole 101 corresponds to the position of the loudspeaker 510 on the slide rail 530, ensuring that the loudspeaker 510 can effectively transmit sound through the sound hole 101 when moved to different positions. The sound hole 101 can be a single opening structure or a long slot-shaped acoustic opening structure.

[0033] When the sound source acquisition component 40 detects the location of the tourist's sound source, the control terminal 20 sends a control command according to the location of the sound source, driving the sliding component 520 to move the speaker 510 along the slide rail 530, so that the sound output position of the speaker 510 is closer to the direction of the line connecting with the tourist, thereby forming a clearer directional output of the sound source, making the output sound wave have a clearer physical direction, and enabling the voice feedback to act more concentrated on the tourist interacting with the sign, reducing the waste of sound energy and noise interference caused by the sound spreading to other directions.

[0034] Furthermore, the sound source acquisition component 40 includes microphones 410, with multiple sets of microphones 410 respectively disposed on the housing 110 along its length. These microphones are used to acquire sound from different locations around the sign and transmit the acquired information to the control terminal 20. The control terminal 20 compares the sound from different locations and instructs the sliding component 520 to drive the speaker 510 to slide towards the position with the highest volume. Specifically, the microphones 410 can employ acoustic acquisition devices such as condenser microphones, electret microphones, or miniature digital pickup modules. These devices are all mature and reliable sound sensing components in the prior art, capable of effectively sampling the spatial sound intensity and source direction.

[0035] In practical operation, each microphone 410 transmits its own location's sound sampling data to the control terminal 20 in real time. The control terminal 20 compares the sound intensity and time difference from different pickup points, and by comparing and analyzing the changes in sound volume and distribution differences, determines the current location of the tourist's voice. Combining the recognition results from the sound source acquisition component 40, the control terminal 20 sends a control command to the sliding component 520, causing the sliding component 520 to drive the speaker 510 along the slide rail 530 towards the pickup point with the highest sound intensity, so that the speaker 510 is ultimately positioned closest to the direction from which the tourist's sound originates. Since the slide rail 530 is arranged along the length of the outer casing 110, the speaker 510 can move continuously in this direction. Through physical position adjustment, it achieves stronger sound source directivity, making the output speech more concentrated and radiating to the tourist's area, enhancing the clarity and recognizability of the sound during interaction.

[0036] Furthermore, a guide plate 60 is provided inside the sound hole 101. The guide plate 60, located on the left side along the length of the outer casing 110, is positioned in a first position within the sound hole 101, used to transmit the sound source of the speaker 510 to the left side of the outer casing 110. The guide plate 60, located in the middle along the length of the outer casing 110, is positioned in a second position within the sound hole 101, used to transmit the sound source of the speaker 510 to the front side of the outer casing 110. The guide plate 60, located on the right side along the length of the outer casing 110, is positioned in a third position within the sound hole 101, used to transmit the sound source of the speaker 510 to the right side of the outer casing 110. Specifically, the guide plate 60 can adopt conventional acoustic structures such as plastic acoustic reflectors, metal sound guides, or composite material acoustic guides. These structures can deflect and converge sound waves by changing their propagation path.

[0037] A guide plate 60, located on the left side along the length of the outer casing 110, is positioned at a first position within the sound hole 101. When the speaker 510 slides to the left region under the drive of the sliding member 520, the sound output by the speaker 510 is reflected or deflected by the guide plate 60 at the first position, causing the sound waves to propagate towards the left side of the outer casing 110. A guide plate 60, located in the middle of the length of the outer casing 110, is positioned at a second position within the sound hole 101. When the speaker 510 is in the middle region, this guide plate 60 guides the sound waves to be output towards the front of the outer casing 110, making it most suitable for tourists or patrol personnel facing the front of the signboard, achieving clear forward broadcasting. A guide plate 60, located on the right side along the length of the outer casing 110, is positioned at a third position within the sound hole 101. It is used to deflect the sound to the right side of the outer casing 110 when the speaker 510 slides to the right region, enabling this embodiment to cover the audio needs of tourists on the right side. This achieves a wider sound propagation range, effectively expands the coverage area of ​​the voice broadcast, and improves the overall audio propagation effect.

[0038] Furthermore, the guide plate 60 includes a first partition 610 and a second partition 620. An opening / closing assembly 70 is also provided within the sound hole 101. The opening / closing assembly 70 includes a mounting post 710 and a driving component 720. The first partition 610 and the second partition 620 are rotatably mounted on the mounting post 710. The driving component 720 is communicatively connected to the control terminal 20 and is used to drive the first partition 610 and the second partition 620 to rotate along the mounting post 710 in a direction that moves closer to or further away from each other. Specifically, the first partition 610 and the second partition 620 are both rotatably connected to the mounting post 710, forming a structure that can rotate and open or close around the mounting post 710. The driving component 720 is communicatively connected to the control terminal 20. The control terminal 20 sends control commands to the driving component 720 based on the usage status of the sign, visitor detection information, or working hours, causing the driving component 720 to drive the partitions to rotate along the mounting post 710 in an angle that moves closer to or further away from each other. When the scenic area is open or when a visitor is detected approaching the sign, the control terminal 20 sends a start command to the drive unit 720, causing the drive unit 720 to drive the first partition 610 and the second partition 620 to rotate synchronously in a direction of mutual approach, so that the two partitions fit together, thereby forming a sound guiding channel with a certain shape and direction inside the sound hole 101. This guiding channel can converge the sound waves emitted by the speaker 510, so that the sound waves are transmitted to the outside more concentratedly and efficiently from the sound hole 101, reducing energy loss, thereby improving the sound propagation effect of the speaker 510, achieving audio coverage over a longer distance and stronger directionality, so that visitors can hear more clearly when interacting.

[0039] When the park is closed or no visitors approach the signage for an extended period, the control terminal 20 instructs the drive unit 720 to rotate the first partition 610 and the second partition 620 in a direction away from each other. This causes the two partitions to be in a substantially parallel state and cover the inside of the sound hole 101, thus forming a shielding structure for the sound hole 101. This prevents dust, rainwater, insects, or other external impurities from entering the interior of the outer casing 110, avoiding contamination or corrosion of internal components and ensuring the long-term stable operation of internal components such as the speaker 510, sliding member 520, and drive unit 720. Compared with the traditional structure of the sound hole 101 using a fixed dustproof net or fixed louvers, the automatic closing partition of this embodiment provides more stringent protection when the equipment is not in operation. At the same time, it fully opens the sound channel during operation without affecting sound quality or sound propagation efficiency, structurally achieving the dual functions of sound guidance and equipment protection.

[0040] Furthermore, a first rotating block 611 is provided on the first partition 610, and a second rotating block 621 is provided on the second partition 620. The driving component 720 is used to drive the first rotating block 611 and the second rotating block 621 to rotate along the mounting column 710. Specifically, the driving component 720 is communicatively connected to the control terminal 20. When the control terminal 20 detects that the scenic area is open or that tourists are approaching, the driving component 720 drives the first rotating block 611 and the second rotating block 621 to rotate along the mounting column 710 according to the instruction, so that the first partition 610 and the second partition 620 gradually twist towards each other and finally fit together to form a sound guiding channel. The sound guiding channel is essentially a channel structure that limits the direction of sound wave propagation, so that tourists can obtain clear voice prompts from multiple angles and directions.

[0041] When there are no visitors or the park is closed, the control terminal 20 sends another control command to the drive unit 720, causing the drive unit 720 to drive the first rotating block 611 and the second rotating block 621 to rotate in opposite directions. This causes the first partition 610 and the second partition 620 to gradually unfold along the mounting column 710 in a direction away from each other, and finally to a basically parallel unfolded position. At this time, the two partitions together shield the sound hole 101, forming a protective shielding structure that can effectively prevent external impurities such as dust, leaves, small particles, and rainwater from entering the housing 110 through the sound hole 101, avoiding contamination or moisture damage to the speaker 510 or internal electronic components, thereby improving the durability and long-term operational stability of the equipment.

[0042] Further, the driving component 720 includes a guide frame 721, a slider 722, and an actuator 723. The guide frame 721 is fixed inside the housing 110. The slider 722 is provided with a first limiting groove 7221 and a second limiting groove 7222. A first connecting post 612 is provided on the first rotating block 611 and is inserted into the first limiting groove 7221. A second connecting post 622 is provided on the second rotating block 621 and is inserted into the second limiting groove 7222. The actuator 723 is disposed on the guide frame 721 and is used to drive the slider 722 to slide along the guide frame 721. Specifically, the actuator 723, disposed on the guide frame 721, can be a micro motor, a stepper motor, a gear and rack mechanism, or an electromagnetic drive mechanism, and is used to provide a controllable linear driving force for the slider 722 along the guide frame 721. The actuator 723 is connected to the control terminal 20 and can accurately control the sliding speed and position of the slider 722 according to the equipment status or the approach of tourists.

[0043] During operation, when the control terminal 20 issues a command to open the park or for visitors to approach, the actuator 723 drives the slider 722 to slide along the guide frame 721. Since the first connecting post 612 is inserted into the first limiting groove 7221 and the second connecting post 622 is inserted into the second limiting groove 7222, the linear movement of the slider 722 causes the two connecting posts to slide synchronously, thereby causing the first rotating block 611 and the second rotating block 621 to rotate simultaneously on the mounting post 710. The synchronous rotation of the first rotating block 611 and the second rotating block 621 causes the first partition 610 and the second partition 620 to move closer to each other around the mounting post 710, forming a sound guiding channel. This allows the sound waves emitted by the speaker 510 to propagate in a concentrated direction, improving the directivity and coverage efficiency of the sound, and enhancing the experience and clarity of visitors' voice interaction in front of the sign.

[0044] Conversely, when the park is closed or there are no visitors, the control terminal 20 issues a command to cause the actuator 723 to move the slider 722 in the opposite direction. The first connecting post 612 and the second connecting post 622 move accordingly, and the first rotating block 611 and the second rotating block 621 rotate synchronously, causing the first partition 610 and the second partition 620 to move away from each other and into a parallel state. This covers the sound hole 101, forming a shield to prevent dust, rainwater, or other external impurities from entering the interior of the outer casing 110, thereby protecting the normal operation of the internal speaker 510 and electronic components. Through the linkage design of the slider 722, the limiting groove, and the connecting post, this embodiment achieves high-precision synchronous control of the partition opening and closing action. The structure is simple and reliable, taking into account both the sound propagation effect and the equipment protection performance, significantly improving the practicality, durability, and user experience of the multi-faceted intelligent electronic display sign in outdoor environments.

[0045] Furthermore, the voice adjustment component 50 also includes a conductive track 540 and an electrical contact 550. The extension direction of the conductive track 540 is the same as that of the slide rail 530. The electrical contact 550 is electrically connected to the speaker 510. The conductive track 540 has a groove 541 along its length, and a conductive sheet 542 is provided on the bottom surface of the groove 541. The conductive sheet 542 is connected to an external power supply. The electrical contact 550 slides along the groove 541 and is electrically connected to the conductive sheet 542. Specifically, the conductive track 540 can be made of copper strip, aluminum alloy strip, or composite conductive material, which has good conductivity and mechanical durability and is a structural form well known to those skilled in the art. When the speaker 510 moves along the slide rail 530 with the sliding member 520, the electrical contact 550 slides into the groove 541 of the conductive track 540 and makes contact with the conductive sheet 542, thereby ensuring that the speaker 510 can receive power normally throughout the sliding process.

[0046] In practice, when the speaker 510 moves along the slide rail 530 to the left, middle or right position, the electrical contact 550 slides along the slide groove 541 and maintains reliable contact with the conductive sheet 542, so that the speaker 510 can continuously output sound without being affected by position changes, and avoids the problem of voice broadcast interruption or volume instability caused by power interruption.

[0047] Furthermore, the slide groove 541 has a first groove 543 recessed on both sides, and a first rolling element 544 is rotatably installed in the first groove 543, abutting against the side wall of the electrical contact 550; the slide groove 541 has a second groove 545 recessed on the top wall, and a second rolling element 546 is rotatably installed in the second groove 545, abutting against the top surface of the electrical contact 550. Specifically, the first rolling element 544 and the second rolling element 546 can be ball bearings, rollers, or rollers, and their function is to provide vertical and lateral support for the electrical contact 550, so that the electrical contact 550 remains stable during sliding and avoids tilting or deviation, thereby ensuring stable and reliable contact between the electrical contact 550 and the conductive sheet 542.

[0048] In practical implementation, when the speaker 510 and its associated electrical contact 550 move along the slide rail 530, the first rolling element 544 contacts the side wall of the electrical contact 550, and the second rolling element 546 contacts the top surface of the electrical contact 550, providing good mechanical constraint and support for the electrical contact 550 in both the horizontal and vertical directions. Through the rotational support of the rolling elements, the frictional resistance of the electrical contact 550 is reduced as it slides within the conductive track 540, ensuring smooth sliding operation and reducing the wear on the electrical contact 550 and the conductive sheet 542, thereby extending their service life.

[0049] Furthermore, a filter 102 is provided on the outer peripheral surface of the sound hole 101. Specifically, the filter 102 can be made of metal mesh, plastic mesh, or composite fiber mesh. Its main function is to block dust, impurities, insects, and other small particles from entering the sound hole 101, while not significantly affecting the sound propagation emitted by the speaker 510. The filter 102 is fixed to the outer peripheral surface of the sound hole 101 by means of threads, snaps, or embedded installation, ensuring a stable installation and facilitating later cleaning and replacement. The filter 102, while ensuring air and sound wave circulation, improves the protection level of the equipment and extends the service life of internal components.

[0050] In summary, the multi-faceted intelligent electronic display signage provided in this embodiment achieves multi-directional information display and adaptive adjustment of voice output, making the broadcast content clear, the direction accurate, and enhancing the interactive experience for tourists.
