Description

Technical Field

[0001] This utility model relates to the field of exhibition equipment technology, specifically to an immersive exhibition device. Background Technology

[0002] In modern exhibitions and trade fairs, in order to fully showcase exhibits and enhance the viewing experience, many exhibition devices use sound and light technologies to significantly enhance the immersive experience.

[0003] Traditional centralized sound reinforcement cannot adjust the volume according to the actual situation. When the sound pressure level in the exhibition hall exceeds the 65-decibel threshold (close to the noise level of a busy street), continuous exposure will trigger the body's stress defense mechanism, forcing the audience to repeatedly tug-of-war between auditory overload and information anxiety. When the reverberation time exceeds 1 second, the acoustic environment causes the speech intelligibility to drop sharply by 40%, resulting in key information being drowned out by noise. On the other hand, if the volume is deliberately reduced to avoid noise pollution, in exhibition halls with high daily traffic, the audience has to compete with background noise (including other explanatory equipment, conversations, etc.) from 3 meters away, ultimately falling into a vicious cycle of "high volume is harsh, low volume is distorted". This either-or acoustic dilemma forces the audience to constantly consume cognitive resources between "passively resisting interference" and "actively searching for the sound source", completely undermining the immersion and focus required for the exhibition narrative. Utility Model Content

[0007] Furthermore, the two support mechanisms have the same structure, including a rectangular frame fixedly connected to the lower surface of the storage box, a rotating shaft connected to the inner wall of the rectangular frame, two parallel telescopic rods fixedly connected to the rotating shaft, a connecting rod fixedly connected between the two telescopic rods, and a tightening bolt threaded onto each of the two telescopic rods.

[0008] Furthermore, a self-locking caster wheel is installed at the lower end of the telescopic rod.

[0009] Furthermore, the fixing assembly includes two rotating blocks fixedly connected to the connecting rod, a second rotating shaft rotatably connected between the two rotating blocks, a second telescopic rod fixedly connected to the second rotating shaft, and a second tightening bolt threadedly connected to the second telescopic rod.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1 to 4 An immersive exhibition device includes a display screen 1, an audio player 2 electrically connected to the display screen 1, a Bluetooth transmitter 3 electrically connected to the audio player 2, and several Bluetooth headsets 4 paired with the Bluetooth transmitter 3.

[0020] like Figures 1 to 4 As shown, in use, the immersive exhibition equipment of this utility model connects the display screen 1 and the audio player 2 via a data cable to play the exhibition content. Before the exhibition, the Bluetooth transmitter 3 is connected to the audio player 2 via an audio cable. The display screen 1 plays external sound and video normally. The Bluetooth transmitter 3 supports LEAudio broadcast mode and automatically broadcasts an audio stream (similar to a "radio station") after being powered on. After being powered on, the eight Bluetooth headsets 4 scan for signals through their built-in Bluetooth chips and automatically subscribe to the broadcast stream without manual pairing, completing a "one-to-many" connection. The entire process takes only a few seconds and supports wireless devices (actually limited by the transmitter performance). The latency is as low as 50ms, which is suitable for real-time scenarios. When visitors are very interested in this part of the exhibition content, they can wear the Bluetooth headsets 4 themselves to avoid being affected by the noisy external environment and to experience the exhibition content immersively on their own.

[0021] like Figure 2 To and Figure 4 As shown, the Bluetooth headset 4 is placed on the storage mechanism, which is equipped with two foldable support mechanisms. The two support mechanisms are fixed together by a fixing component. The storage mechanism includes a storage box 5, which is divided into several storage chambers 6. Two sets of sliding grooves 7 are provided on both sides of the inner wall of the storage box 5, and transparent cover plates 8 are slidably connected in both sets of sliding grooves 7.

[0022] Specifically, when visitors are interested in the exhibition content, they can push the transparent cover 8 to move it inside the slide 7, opening the storage chamber 6 to retrieve the Bluetooth headset 4. The volume can be adjusted on the Bluetooth headset 4 so that visitors will not hear external noise or the impact of external noise on them can be greatly reduced, thus providing an immersive experience of viewing the exhibition content. It is convenient to use.

[0023] like Figure 4 As shown, the two support mechanisms have the same structure, including a rectangular frame 9 fixedly connected to the lower surface of the storage box 5. A rotating shaft 10 is rotatably connected to the inner wall of the rectangular frame 9. Two parallel telescopic rods 11 are fixedly connected to the rotating shaft 10. A connecting rod 12 is fixedly connected between the two telescopic rods 11. Tightening bolts 13 are threadedly connected to both telescopic rods 11.

[0024] Specifically, the connecting rod 12 is pushed so that the two telescopic rods 11 rotate with the pivot 10 until the two telescopic rods 11 are perpendicular to the ground. Then, the bolt 13 is turned and tightened so that the length of the two telescopic rods 11 can be adjusted to change the height between the storage box 5 and the ground.

[0025] like Figure 4 As shown, a self-locking caster wheel 20 is installed at the lower end of the telescopic rod 11.

[0026] Specifically, the self-locking casters 20 facilitate the movement of the storage box 5 and multiple Bluetooth headsets 4, further increasing ease of use.

[0027] like Figure 4 As shown, the fixing assembly includes two rotating blocks 14 fixedly connected to the connecting rod 12, a rotating shaft 15 rotatably connected between the two rotating blocks 14, a telescopic rod 16 fixedly connected to the rotating shaft 15, and a tightening bolt 17 threadedly connected to the telescopic rod 16.

[0028] Specifically, when the telescopic rod 11 rotates with the pivot 10, the distance between the two support mechanisms changes accordingly. During this process, the telescopic rod 16 is gradually lengthened. When the telescopic rod 11 is perpendicular to the ground, tightening the bolt 17 fixes the length of the telescopic rod 16, thereby fixing the position of the two support mechanisms to ensure the balance of the storage box 5.

[0029] like Figures 2 to 4 As shown, a battery 18 is fixedly connected to the lower surface of the storage box 5. A multi-port USB charging module is provided on the battery 18. Multiple charging cables 19 are connected to the multi-port USB charging module. The charging cables 19 pass through the bottom of the storage box 5 and are connected to the Bluetooth headset 4.

[0030] Specifically, after the DC power output from battery 18 is connected to the multi-port USB charging module, the module uses its internal MCU (microcontroller) to monitor the voltage, current, and device connection status of each port in real time (such as the Bluetooth headset's battery type and real-time battery level). Based on the load detection results, the module uses an intelligent current distribution algorithm to dynamically allocate power (e.g., a single port supports a maximum of 2.4A, automatically adjusting to 1.5A / port when multiple ports are working simultaneously) to ensure charging efficiency and device safety. The charging protocol adaptation and voltage regulation module supports mainstream fast charging protocols such as QC 3.0 and PD 3.0, automatically identifying the charging requirements of the Bluetooth headset 4 (such as 5V / 1A or 9V / 1A) and dynamically adjusting the output voltage using PWM (pulse width modulation) technology to avoid charging interruptions or device overheating due to protocol incompatibility. The module also implements automatic stop logic after full charge. Battery status monitoring: The module samples the voltage and current curves of the Bluetooth headset 4 battery in real time and uses a built-in algorithm to determine whether the battery is fully charged. When the MCU detects that the battery of the Bluetooth headset connected to a certain port has reached full charge, it immediately controls the MOSFET switch of that port to cut off the current output. At the same time, the status of the port is displayed by an LED indicator (e.g., a solid green light indicates that it is fully charged). After the power supply is cut off, the module automatically enters a low-power standby state to avoid overcharging or energy waste caused by continuous power supply.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
