Description

Technical Field

[0001] The invention relates to the technical field of audio, and in particular to a movable bracket for outdoor audio. Background Art

[0002] The importance of audio equipment in outdoor activities such as concerts, outdoor parties or commercial promotions is self-evident. As an important auxiliary equipment to ensure the sound effect and equipment safety, the design and function of the audio stand have a significant impact on the success of the event. However, the existing technology has many inconveniences in the design and use of outdoor audio activity stands, and technical innovation and improvement are urgently needed.

[0003] Traditional outdoor audio brackets have the following major shortcomings: First, the installation and disassembly process of the audio equipment is cumbersome. Each time it is used, the user needs to install the audio on the bracket by means of screws, snap connections, etc., and then disassemble it after the activity. This not only consumes a lot of time and labor, but also causes frequent wear and tear on the connecting parts of the audio equipment and the bracket, reducing its service life.

[0004] Secondly, it is inconvenient to adjust the sound direction of the speakers. Traditional brackets are mostly fixed designs. Once the speakers are installed, their sound direction is fixed. In actual applications, the direction of the speakers often needs to be adjusted according to the changes in the on-site environment and the distribution of the audience. The current solution is usually to adjust the direction by manually moving the bracket or the speakers, which is not only troublesome to operate, but also easy to cause equipment damage. Although some brackets use a rotating mechanism to solve this problem, this type of design often makes the structure complex, increases product cost, and easily causes the bracket to overturn when used on unstable ground.

[0005] Finally, it lacks adaptability to outdoor use environments. The outdoor environment is complex and changeable, such as uneven ground, strong winds, vibrations, etc., which put forward higher requirements on the stability and seismic resistance of the bracket. The existing bracket design is often difficult to meet these harsh external conditions, especially in protecting electronic products such as audio installed on the bracket. Summary of the invention

[0006] In order to solve the above problems, the present invention provides a movable bracket for outdoor audio, which can effectively solve the deficiencies in the prior art.

[0007] The present invention is realized by the following technical scheme: a movable bracket for outdoor audio, comprising:

[0018] A central hinge rod is arranged in the second hinged bracket, and the second bracket rod is rotatably hinged on the central hinge rod through the first hinge sleeve, and the first conductive contact pieces are fixedly mounted on the central hinge rod, and the circumferential positions of each group of first conductive contact pieces arranged on the central hinge rod are the same. As the size of the floating cavity between the floating support tube and the fixed support tube changes, the speaker components in different circumferential directions can be connected.

[0019] As a preferred technical solution, the second articulated sleeve is hinged on an articulated connecting member, a third articulated sleeve is provided at one end of the first support rod, and a fourth articulated sleeve is provided at the other end of the first support rod, the first support rod is articulated on the articulated connecting member through the third articulated sleeve, the first support rod is elastically articulated in the first articulated bracket through the fourth articulated sleeve, a torsion spring is installed between the fourth articulated sleeve and the first articulated bracket, and the torsion spring is used to make the first support rod have an elastic torsional force relative to the first articulated bracket.

The bottom of the fixed support tube is fixedly installed on the support base plate, and the first articulated bracket is arranged in a circle around the support base plate.

[0021] As a preferred technical solution, the magnetic attraction control component includes an electromagnet arranged in a first positioning cavity, and a permanent magnet arranged in a second positioning cavity. When the electromagnet is energized, the electromagnet generates a magnetic attraction force to attract the permanent magnet located in the second positioning cavity, and changes the size of the floating cavity between the fixed support tube and the floating support tube by changing the magnetic attraction force of the electromagnet, thereby controlling the opening and closing of the speaker components in different circular surfaces. The electromagnet is controlled to open and close by the control host.

[0022] As a preferred technical solution, the speaker assembly includes a plurality of speakers installed in a second support rod, a mounting cavity is provided on the second support rod, a plurality of speakers are arranged in an "I" shape in the mounting cavity, and a sound outlet grille is installed at the external opening of the mounting cavity.

[0023] The beneficial effects of the present invention are as follows: when the outdoor audio active bracket of the present invention is not in use, the battery assembly is installed between the fixed support tube and the floating support tube, at which time the angle between the first bracket rod and the second bracket rod is the largest and close to 180 degrees, and the cross-sectional area of ​​the entire active bracket becomes smaller, which is convenient for carrying and storage;

[0024] When in use, the present invention can disassemble the battery assembly, and at this time a floating cavity is formed between the fixed support tube and the floating support tube. The battery assembly, as a power supply assembly and a counterweight assembly, applies gravity to the floating support tube, and the entire bracket is unfolded by the weight of the battery assembly, so that the angle between the first bracket rod and the second bracket rod becomes smaller, and the entire movable bracket is in an unfolded suspended state. By utilizing this structure in the suspended state, the seismic resistance of the entire battery assembly, the control mainboard and the speaker assembly is greatly improved, and the outdoor complex environment can be effectively coped with;

[0025] Furthermore, the present invention is a stowed bracket when not in use. When in use, the battery assembly can be disassembled to unfold the bracket and serve as a combination of a movable bracket and a speaker. Therefore, the battery assembly can be disassembled and installed on the top of the floating support tube to serve as an integrated structure of a speaker and a bracket. The integrated structure is used to complete outdoor support and sound playback. A complex bracket structure is not required, and the speaker does not need to be installed on the movable bracket. The steps are simplified, the efficiency of disassembly and installation is improved, and the use is convenient.

[0026] The most important thing is that the present invention only needs to control the magnetic control component to adjust the spacing of the floating cavity between the floating support tube and the fixed support tube. As the spacing of the floating cavities changes, the opening and closing of the speaker components in different circular surfaces can be switched accordingly. Therefore, the present invention only needs to control the floating support tube to perform lifting and lowering actions to switch the speakers in different directions to play sounds. The sound playback direction can be switched without rotation, so that the entire movable bracket is more stable when placed outdoors. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0038] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0039] like Figure 3 and Figure 4 As shown, a movable bracket for outdoor audio of the present invention comprises a fixed support tube 2, the upper end of the fixed support tube 2 has a first positioning cavity, the lower end of the fixed support tube 2 is fixedly mounted on a support frame, and the support frame is provided with a plurality of first hinged brackets 20, and a first bracket rod 17 is elastically hingedly provided in each first hinged bracket 20;

[0040] It also includes a floating support tube 13, which is installed on the upper end of the fixed support tube 2 and forms a floating cavity L with the fixed support tube 2. Figure 3 , Figure 4 as well as Figure 5 As shown, a second hinged bracket 11 is provided at the top of the floating support tube 13 corresponding to each first hinged bracket 20, a second bracket rod 15 is hingedly provided in the second hinged bracket 11, the first bracket rod 17 is hinged to the second bracket rod 15, when the entire movable bracket is stored, the hinged position between the first bracket rod 17 and the second bracket rod 15 is opened, that is, close to a vertical state, so that the entire bracket is small in size and convenient to carry, the other ends of the first bracket rod 17 and the second bracket rod 15 are also hinged, so both sides of the first bracket rod 17 and the second bracket rod 15 can be rotated, which can have greater rotation flexibility;

[0041] A speaker assembly is arranged in each second bracket rod 15, and each second bracket rod 15 is arranged around the floating support tube 13 and the fixed support tube 2 in a circle, so as to form different sound output surfaces in the circumferential direction. A magnetic control assembly is arranged on the opposite side of the floating support tube 13 and the fixed support tube 2, and the size of the floating cavity of the floating support tube 13 and the fixed support tube 2 is controlled by the magnetic control assembly, so as to switch different sound output surfaces in the circumferential direction.

[0042] like Figure 1 and Figure 2As shown, it also includes a battery assembly 3. When the battery assembly 3 is not in use, the bottom of the battery assembly 3 is positioned and installed in the first positioning cavity, and the bottom surface of the floating support cylinder 13 is provided with a second positioning cavity. The top of the battery assembly 3 is positioned and installed in the second positioning cavity, and the upper and lower ends of the battery assembly 3 are positioned and installed in the first positioning cavity and the second positioning cavity. When not in use, the floating support cylinder 13 is lifted up by the battery assembly 3, so that the hinged ends of the first bracket rod 17 and the second bracket rod 15 are stretched. At this time, the hinged end angle of the first bracket rod 17 and the second bracket rod 15 becomes larger, and the entire movable bracket is stretched longitudinally, so that the entire movable bracket can reduce the lateral area and is convenient to carry. At the same time, the battery assembly 3 can also be used as a storage component, and the battery assembly 3 is used to keep the entire movable bracket in a storage state. Only when the battery assembly 3 is removed can the entire bracket be opened, and the first bracket rod 17 and the second bracket rod 15 can be relatively rotated and opened;

[0043] When the battery assembly 3 is in use, the battery assembly 3 is disassembled and installed in the battery assembly cavity 9 at the top of the floating support tube 13. The battery assembly 3 is used to power each speaker assembly and the control mainboard in the floating support tube 13, and the battery assembly 3 is used as a downward counterweight for the floating support tube 13. The battery assembly 3 can be used to apply gravity to the movable support tube, so that the hinge angle between the first bracket rod 17 and the second bracket rod 15 becomes smaller, and the lateral area of ​​the first bracket rod 17 and the second bracket rod 15 becomes larger, and the entire bracket is automatically in an expanded use state. The battery assembly 3 can be used as a power supply component, and its gravity can be used to complete the automatic expansion and use of the bracket in one step.

[0044] In order to increase the guiding ability of the battery assembly 3 when installed in the battery assembly cavity 9, in this embodiment, the outer wall surface of the battery assembly 3 is provided with a plurality of protruding guide rods 4, the inner wall of the battery assembly cavity 9 is provided with corresponding guide slots 10, and the outer wall surfaces of the guide rods 4 are provided with buckle slots, and the positions corresponding to the buckle slots in the guide slots 10 are provided with protruding buckles. When the battery assembly 3 is installed in the battery assembly cavity 9, the buckles are buckled into the buckle slots to fix the battery assembly 3 in the battery assembly cavity 9.

[0045] like Figure 1 As shown, a conductive contact pin 8 is provided on the bottom surface of the battery assembly cavity 9, and a conductive contact point is provided at the bottom position corresponding to the battery assembly 3. When the battery assembly 3 is assembled in the battery assembly cavity 9, the conductive contact point contacts and the conductive contact pin 8 for electrical conduction. After installation, the entire speaker assembly can be powered, and disassembly and assembly are convenient.

[0046] Among them, a control host 7 is installed on the outside of the floating support cylinder 13, and a control mainboard fixedly installed in the floating support cylinder 13 is connected to the control host 7, and the control mainboard is conductively connected to the conductive contact pin 8 on the bottom surface of the battery assembly cavity 9. A plurality of control wiring positions are arranged on the control mainboard, and the output end of each group of control wiring positions is connected to a group of first conductive contact pieces 26 through a first conductive connecting line, and a group of second conductive contact pieces 27 are arranged at the hinged end of each second support rod 15 and the second hinged support 11, and each group of second conductive contact pieces 27 are connected to the speaker assembly in the second support rod 15 through a second conductive connecting line 28, such as Figure 7 shown.

[0047] Specifically, a first hinge sleeve 12 is provided at one end of the second bracket rod 15, and a second hinge sleeve 6 is provided at the other end of the second bracket rod 15. The inner circumferential surface of each first hinge sleeve 12 forms an articulated assembly cavity, and a group of second conductive contacts 27 are installed in each articulated assembly cavity. The circumferential positions of the second conductive contacts 27 in each articulated assembly cavity are different in the articulated assembly cavity. In other words, the opening orientations of the corresponding loudspeaker assemblies are different for different floating cavity sizes. For example, when the floating cavity spacing is at the maximum, several loudspeaker assemblies within a certain circumferential range are opened, while the remaining loudspeaker assemblies are in a closed state. As the floating cavity becomes smaller, the opening and closing of the loudspeakers within the circumferential range are continuously switched. Therefore, the playing direction of the loudspeaker can be switched by controlling the spacing of the floating cavity without rotating the entire structure. Through the lifting control, the entire bracket is more stable to use.

[0048] Among them, Figure 3 and Figure 6 As shown, a central hinge rod 21 is provided in the second hinged bracket 11, and the second bracket rod 15 is rotatably hinged on the central hinge rod 21 through the first hinge sleeve 12, and the first conductive contact pieces 26 are fixedly mounted on the central hinge rod 21, and the circumferential positions of each group of first conductive contact pieces 26 arranged on the central hinge rod 21 are the same. With the change of the size of the floating cavity between the floating support tube 13 and the fixed support tube 2, the speaker components in different circumferential directions can be connected. When the size of the floating cavity changes, the position of the first hinge sleeve 12 in the circumferential direction relative to the central hinge rod 21 can be changed, so as to realize the contact or separation between the conductive contacts in different orientations, and complete the switch switching of the speaker components in different orientations. When the second conductive contact piece 27 in the first hinge sleeve 12 is separated from the first conductive contact piece 26 on the central hinge rod 21, the speaker component at this position can be powered off and not work. On the contrary, the second conductive contact piece 27 contacts the speaker component at the position of the first conductive contact piece 26 to open, thereby realizing orientation switching.

[0049] Among them, the second hinge sleeve 6 is hingedly set on an hinged connecting member 16, a third hinge sleeve 5 is set at one end of the first bracket rod 17, and a fourth hinge sleeve 19 is set at the other end of the first bracket rod 17. The first bracket rod 17 is hingedly set on the hinged connecting member 16 through the third hinge sleeve 5, and the first bracket rod 17 is elastically hinged in the first hinge bracket 20 through the fourth hinge sleeve 19. A torsion spring is installed between the fourth hinge sleeve 19 and the first hinge bracket 20. Through the torsion spring, the first bracket rod 17 has an elastic torsional force relative to the first hinge bracket 20. Through the elastic torsional force, the first bracket rod 17 has the ability to elastically lift up. When pressure is applied to the battery assembly 3 from the top, the first bracket rod 17 will open outward, and the torsion spring can undergo elastic torsion.

[0050] like Figure 1-Figure 4 As shown, the support frame includes a support base plate 1 and a plurality of support legs 18 that can be folded and opened and are arranged at the bottom of the support base plate 1. The bottom of the fixed support tube 2 is fixedly installed on the support base plate 1. The first hinged bracket 20 is arranged in a circle around the support base plate 1. The support legs 18 can be opened and stored, which is convenient for the storage and opening of the entire movable bracket, and the bottom support is completed by using the support legs 18.

[0051] like Figure 4 and Figure 5 As shown, the magnetic attraction control component includes an electromagnet 22 arranged in a first positioning cavity, and a permanent magnet 23 arranged in a second positioning cavity. When the electromagnet 22 is energized, the electromagnet 22 generates a magnetic attraction force to attract the permanent magnet 23 located in the second positioning cavity, and changes the size of the floating cavity between the fixed support tube 2 and the floating support tube 13 by changing the magnetic attraction force of the electromagnet 22, thereby controlling the opening and closing of the speaker components in different circular surfaces. The electromagnet 22 is controlled to open and close by the control host 7, so when the playing direction of the speaker needs to be switched, the magnetic attraction force of the electromagnet 22 can be controlled by controlling the current of the electromagnet 22, thereby completing the spacing adjustment of the floating cavity.

[0052] The speaker assembly includes a plurality of speakers 24 installed in the second support rod 15. The second support rod 15 is provided with an installation cavity 25. The plurality of speakers 24 are arranged in a "one" shape in the installation cavity 25. A sound outlet grille 14 is installed at the external opening of the installation cavity 25.

[0053] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
