In some embodiments, at least part of the data lines and / or conductive wires can be arranged in the wire arrangement slot, and at least part of the data lines and / or conductive wires can pass through the wire arrangement slot.

[0054] In some embodiments, the wire arrangement slot is provided with a wire arrangement hole through which the data lines and / or conductive wires can pass. Different data lines and / or conductive wires pass through different wire arrangement holes. By providing the wire arrangement module, at least part of the data lines and / or conductive wires can be stored in the wire arrangement module, avoiding the mutual entanglement of multiple data lines and / or conductive wires, which makes it difficult to arrange. By making the data lines and / or conductive wires pass through the corresponding wire arrangement holes, the data lines and / or conductive wires can be easily identified and managed.

[0055] In some embodiments, the cable management module includes a first cable management groove 171 and a second cable management groove 172. Data cables can pass through the first cable management groove 171 and connect to the interface 121, while conductive wires can pass through the second cable management groove 172 and connect to the socket 161.

[0056] In some embodiments, the housing 100 has multiple layers of storage space. Functional modules are located in at least two of the multiple layers of storage space.

[0057] In some embodiments, the accommodating space can be arranged horizontally, and multiple accommodating spaces can be arranged vertically (e.g., Figure 4 The receiving space is disposed within the housing 100 in the Z direction. In some embodiments, the receiving space may be arranged along the vertical direction (e.g., Figure 4 The Z-direction setting allows for multi-layered storage spaces to be set horizontally within the housing 100.

[0058] In some embodiments, such as Figure 4 As shown, the functional modules are arranged in at least two layers of the multi-layered storage space. For example, the control panel module 140 and Bluetooth module 150 are arranged in the same layer. The smart host module 110 and the first cable management channel 171 are arranged in the same layer.

In some embodiments, the first cable management channel 171 and the second cable management channel 172 are located on different sides of the PoE switch module 120. This facilitates the separation of data cables and conductive cables, thereby simplifying their management.

[0059] Arranging functional modules in layers according to their storage space makes their distribution neater and helps improve the utilization of space within the enclosure.

[0060] The rollers 300 can be used to support the housing 100 and move the housing 100 by rotating, making the movement of the housing 100 more convenient. In some embodiments, the rollers 300 are distributed at the corners of the bottom surface of the housing 100. In some embodiments, the rollers 300 are rotatably connected to the housing 100. In some embodiments, the rotation centers of the plurality of rollers are parallel and / or collinear with each other.

[0061] As an example only, the bottom of the housing 100 is provided with four rollers 300, with each pair of rollers 300 forming a group, and the rotation centers of the rollers 300 within each group being collinear. The rotation centers of the corresponding rollers 300 in the two groups are parallel.

[0062] In some embodiments, the rollers 300 are made of an elastic material, such as at least one of rubber or silicone. This reduces vibration when the housing 100 moves, preventing components within the functional modules from becoming loose or damaged due to vibration, and preventing loosening of data cables and / or conductive wire connections.

[0063] In some embodiments, the roller 300 and the housing 100 are connected by an elastic structure. This elastic structure may include at least one of a spring, an elastic pad, etc. Using an elastic structure can reduce vibrations transmitted from the roller 300 to the housing 100.

[0064] In some embodiments, the rollers 300 may be casters. This facilitates changing the direction of movement of the housing 100.

[0065] The cover 200 protects the enclosure 100 and its internal functional modules. When the enclosure 100 is moved, the cover 200 connects to the enclosure 100 to prevent external impurities from entering. In some embodiments, two covers 200 are provided, one connected to the side of the enclosure 100 with the receiving space and the other to the side with the playback hole 101. When using the enclosure 100, the cover 200 can be removed to expose the playback hole 101 and the functional modules.

[0066] In some embodiments, the lid 200 and the body 100 are detachably connected in a variety of ways, such as snap-fit, fastening, etc.

[0067] In some embodiments, one side of the lid 200 can be rotatably connected to the box body 100. For example, the side of the lid 200 near the bottom of the box body 100. In some embodiments, the side of the lid 200 that fits against the box body 100 can be rotated to a horizontal position. After flipping the lid 200 over, it can be used as a platform to place other items.

[0068] In some embodiments, the lid 200 is flexibly connected to the body 100. For example, an elastic gasket is provided between the lid 200 and the body 100 to prevent collisions between the lid 200 and the body 100 when the body 100 is moved.

[0069] like Figure 2 As shown, the cover 200 is equipped with multiple microphones (not shown in the figure). The microphones are communicatively connected to the smart host module 110.

[0070] The microphone can collect a sound signal and transmit the sound signal to the intelligent host module 110, so that the intelligent host module 110 can subsequently process the sound signal. For example, the sound signal is amplified and played through the sound box module 130. In some embodiments, the microphone can be connected to the intelligent host module 110 in various ways. For example, at least one of wired connection, wireless connection, etc.

[0071] By providing the microphone, the user can input the sound signal that the user wants to play to the intelligent host module, thereby enhancing the interactivity and functionality of the audio amplification system and the user.

[0072] In some embodiments, the box cover 200 is provided with a plurality of microphone grooves 210. The microphone grooves 210 are adapted to the microphone, and the microphone grooves 210 are detachably connected to the microphone.

[0073] The microphone groove 210 is used to install the microphone, so that the microphone can sink into the inside of the box cover 200, avoiding the formation of a protruding structure of the microphone relative to the surface of the box cover 200, and avoiding the contact between the microphone and the functional module to cause extrusion when the box body 100 is connected to the box cover 200.

[0074] In some embodiments, the microphone groove 210 and the microphone are connected in various ways, for example, at least one of clamping, buckling, etc.

[0075] In some embodiments, the inner surface of the microphone groove 210 is provided with a plurality of elastic pads. When the microphone is installed in the microphone groove 210, the microphone can extrude the elastic pads to be clamped in the microphone groove 210. In this way, the connection strength of the microphone groove 210 and the microphone can be improved, and the vibration transmitted to the microphone can be reduced to prevent the microphone from being damaged or falling off due to vibration.

[0076] Some embodiments of the present specification provide an audio amplification system. The audio amplification system is provided with a plurality of functional modules, and the plurality of functional modules are arranged in the box body. The plurality of functional modules can be installed in the box body according to actual needs, thereby improving the practicability and applicability of the audio amplification system.

[0077] Figure 5 is a structural schematic diagram of an audio amplification system according to some embodiments of the present specification.

[0078] As shown in Figure 5 , one side of the box body 100 is provided with a support 400. The support 400 can be detachably connected to the microphone.

[0079] The support 400 can serve as a support base for supporting the microphone. When the audio amplification system is in use, the user can temporarily place the microphone on the support 400 after taking out the microphone, without the need to frequently place the microphone in or take the microphone out of the microphone slot 210, thereby facilitating unified management of the microphone and subsequent reuse of the microphone.

[0080] In some embodiments, the support 400 has a height dimension along a vertical direction (e.g., the Z direction in the coordinate system shown in FIG. 1). For example, 1.2 m, 1.5 m, or other values, and the specific dimension can be set according to actual needs. This facilitates the user to take out or place the microphone without bending over. Figure 5

[0081] Figure 6 FIG. 4 is a structural schematic view of a transverse portion of a support according to some embodiments of the present specification.

[0082] In some embodiments, the support 400 has a T-shaped structure, and the support 400 includes a transverse portion 410 and a vertical portion 420.

[0083] In some embodiments, the transverse portion 410 is arranged at the top (e.g., the end portion upward along the Z direction in the coordinate system shown in FIG. 1) of the vertical portion 420. Figure 5

[0084] In some embodiments, the transverse portion 410 is provided with a groove or a connecting hole 411. The microphone can be clamped with the groove or the connecting hole 411. In some embodiments, as shown in FIG. 4, when the connecting hole 411 is arranged on the transverse portion 410, the axis of the connecting hole 411 can be parallel to the vertical direction (e.g., the Z direction in the coordinate system shown in FIG. 1). The connecting hole 411 can be distributed along the length direction of the transverse portion 410. Figure 6 Figure 5

[0085] In some embodiments, the inner surface of the connecting hole 411 can be adapted to the outer surface of a part of the handle of the microphone.

[0086] In some embodiments, the inner surface of the groove or the connecting hole 411 can be provided with an elastic pad layer, which is used to flexibly contact the microphone, so as to avoid damage to the microphone or the transverse portion 410 due to collision between the microphone and the transverse portion 410.

[0087] The vertical portion 420 is used to support the transverse portion 410 and control the height of the transverse portion 410. In some embodiments, the length direction of the vertical portion 420 is parallel to the vertical direction (e.g., the Z direction in the coordinate system shown in FIG. 1). Figure 5

[0088] In some embodiments, the vertical portion 420 has a plate-shaped structure. In this way, the strength and carrying capacity of the vertical portion 420 can be increased. ​​​​​

[0089] In some embodiments, the vertical part 420 can also have other shapes. For example, cylindrical, prismatic, etc. The specific shape can be set according to actual needs.

[0090] In some embodiments, the vertical part 420 can be provided with two or other numbers, so as to increase the overall strength and carrying capacity of the vertical part 420. The specific number can be set according to actual needs.

[0091] In some embodiments, the vertical part 420 is a telescopic structure.

[0092] In some embodiments, the vertical part 420 can include a plurality of support units, and adjacent two support units can be connected in a sliding manner, and the sliding direction is parallel to the vertical direction (for example, the Z direction in FIG. Figure 5 ).

[0093] The vertical part is designed as a telescopic structure, so that the height of the vertical part can be adjusted according to needs to adapt to different user needs.

[0094] The support adopts a T-shaped structure, which can increase the surface area by using the horizontal part, thereby providing sufficient mounting space for the microphone.

[0095] In some embodiments, the support 400 and the box 100 are rotatably connected. In some embodiments, the rotation center of the support 400 relative to the box 100 is perpendicular to the vertical direction (for example, the Z direction in FIG. Figure 5 ). In this way, the angle between the support 400 and the box 100 can be adjusted. In some embodiments, the bottom of the support 400 and the position close to the bottom of one side of the box 100 are rotatably connected.

[0096] In some embodiments, the support 400 and the box 100 can be rotatably connected through a damping structure. After adjusting the angle between the support 400 and the box 100, the position of the support 400 can be kept fixed.

[0097] By rotatably connecting the support and the box, the support can be used as a handle, and the angle between the support and the box can be adjusted according to needs. For example, when going uphill or downhill, adjusting the angle between the support and the box can make the box better adapt to the slope, and the user experience can be improved.

[0098] In some embodiments, the box 100 is provided with a support groove (not shown in the figure).

[0099] The bracket slot is a groove structure recessed inwardly relative to the outer surface of the box 100. The bracket slot can provide a mounting position and positioning for the bracket 400 as a mounting base. At least part of the bracket 400 is detachably connected with the bracket slot. In some embodiments, at least part of the bracket 400 can be rotated into or out of the bracket slot when the bracket 400 is rotated. When the bracket 400 is rotated into the bracket slot, the bracket 400 can be fixed in the bracket slot.

[0100] In some embodiments, the bracket 400 and the bracket slot can be connected in various ways. For example, at least one of clamping, buckling, and the like.

[0101] In some embodiments, the shape of the bracket slot is adapted to at least part of the bracket 400. In some embodiments, when the vertical part 420 of the bracket 400 is a telescopic structure, the bracket slot can be T-shaped. After the vertical part 420 is shortened, the vertical part 420 and the horizontal part 410 can be simultaneously fitted into the bracket slot, avoiding the formation of a protruding structure on the outer surface of the box 100 and the existence of a safety hazard.

[0102] When the bracket is used to support the microphone, the bracket can be fixed in the bracket slot to improve the stability of the bracket and avoid the microphone from falling due to the collapse of the bracket. When the bracket is used as a handle, the bracket can be taken out of the bracket slot to adjust the angle of the bracket according to actual needs, having the advantage of flexible use.

[0103] By providing the bracket that can be used to support the microphone and as a handle, the functionality of the bracket is increased, which is conducive to improving the user experience.

[0104] Figure 7 is a structural schematic view of a storage bag and a protective bag according to some embodiments of the present specification.

[0105] As shown in Figure 7 , the box 100 is provided with a storage bag 500, and the storage bag 500 is provided with a protective bag 510.

[0106] The storage bag 500 is used to store the protective bag 510. In some embodiments, the storage bag 500 is arranged on one side of the box 100.

[0107] The protective bag 510 can play a role of isolation and protection. In some embodiments, the protective bag 510 is configured to be sleeved on the box 100, thereby playing a role of protecting the box 100. In some embodiments, the protective bag 510 is provided with at least one opening, and the protective bag 510 can be sleeved on the box 100 through the opening.

[0108] In some embodiments, the shape of the protective bag 510 after being unfolded is adapted to the shape of the box 100. For example, when the box 100 is hexahedral, the protective bag 510 is also hexahedral after being unfolded.

[0109] In some embodiments, the protective bag 510 is made of elastic material, for example, elastic cloth, which can be deformed adaptively during the process of sleeving the box 100.

[0110] In some embodiments, the opening of the protective bag 510 is provided with an elastic elastic structure. When the protective bag 510 is sleeved on the box 100, the elastic structure is in a contracted state. By tightening the opening with the elastic structure, the gap between the protective bag 510 and the box 100 can be reduced, and the protection effect of the protective bag 510 can be enhanced. During the process of sleeving the box 100, or during the process of removing the protective bag 510, the elastic structure can be deformed adaptively.

[0111] In some embodiments, the protective bag 510 can be detachably connected with the storage bag 500 in various ways. For example, by a zipper. In this way, the protective bag 510 can be detached for replacement, cleaning, etc. as needed.

[0112] By setting the protective bag, the protective bag can be sleeved on the box in the case of wet road surface, rain, dust, etc. so as to protect the box and prevent impurities from entering the box to cause pollution or damage. By setting the storage bag, the protective bag can be conveniently stored, and the space occupied by the protective bag can be reduced.

[0113] Figure 8 is a structural schematic view of a roller according to some embodiments of the present specification.

[0114] As shown in Figure 8 , the box 100 is provided with a plurality of mudguards 310, which are located above the roller 300.

[0115] The mudguard 310 can be used to shield the dust raised by the roller 300 when rotating, so as to prevent the dust raised by the roller 300 from entering the box 100 to cause pollution or damage. In some embodiments, the mudguard 310 can be an arc structure.

[0116] In some embodiments, the mudguard 310 can be detachably connected with the box 100 in various ways. For example, at least one of clamping, threaded connection, etc. In this way, the mudguard 310 can be conveniently detached and replaced as needed.

[0117] In some embodiments, the fender 310 can have a groove-shaped structure in cross section. The cross section of the fender 310 refers to a cross section formed on the fender 310 after the fender 310 is cut by a plane passing through the axis of the roller 300. In some embodiments, at least a portion of the roller 300 can be located in the groove of the fender 310. In this way, the protection effect of the fender 310 can be enhanced.

[0118] In some embodiments, the fender 310 can be provided with a cleaning brush 320 on the surface facing the roller 300.

[0119] The cleaning brush 320 is used to remove impurities attached to the roller 300, so as to avoid the impurities being stuck between the roller 300 and the box 100, thereby increasing the resistance of the roller 300 or preventing the roller 300 from rotating.

[0120] In some embodiments, the cleaning brush 320 can be detachably connected to the fender 310 in various ways. For example, at least one of clamping, threaded connection, etc.

[0121] In some embodiments, the protective bag 510 can be detachably connected to the fender 310 in various ways. For example, at least one of clamping, buckling, etc.

[0122] When the protective bag is sleeved on the box, detachably connecting the protective bag to the fender can improve the stability of the protective bag and can position the protective bag, thereby facilitating the user to quickly sleeve the protective bag. When the protective bag is not needed, the protective bag can also be quickly stored.

[0123] By providing the fender, dust and other impurities raised by the roller can be prevented from entering the box, thereby playing a protection role, and the application range of the audio amplification system can be expanded.

[0124] The above has described the basic concept. Obviously, for those skilled in the art, the above detailed disclosure is only used as an example and does not limit the present specification. Although it is not explicitly stated herein, those skilled in the art can make various modifications, improvements and corrections to the present specification.
