[0038] See also Figures 1 to 8 , the present invention provides a technical solution:

[0039] Embodiment 1:

[0041] The fixing mechanism includes an inner cavity 10 provided on the inner rear side of the fixing shaft 8, the inner cavity 10 is rotatably connected to the rotating shaft 9, the outer surface of the rotating shaft 9 is provided with a thread groove 11, the outer surface of the thread groove 11 is spirally connected to a thread slide 12, the thread slide 12 is slidably connected to the inner cavity 10, a support shell 13 is fixedly installed between the outer surface of the fixing shaft 8 corresponding to the inner cavity 10 and the outer shell 2, the support shell 13 and the inner cavity 10 are communicated with each other, a sealing plate 14 is slidably connected to the inner surface of the support shell 13, an insertion rod 15 is fixedly installed on the upper end of the sealing plate 14, and a fixing groove 4 is provided on the inner wall of the slot 3 corresponding to the insertion rod 15;

[0042] The transmission mechanism is arranged inside the housing 2 and is in transmission connection with the azimuth adjustment mechanism, driving the azimuth adjustment mechanism to adjust the azimuth of the speaker body 5;

[0043] The azimuth adjustment mechanism is arranged at the rear side of the speaker body 5, and is used to adjust the four-way tilt angle of the speaker body 5 through the transmission mechanism, thereby increasing the practicality of the device;

[0044] The protective mechanism is arranged on the outside of the speaker body 5 to protect the speaker body 5 . When the speaker body 5 is in use, the protective mechanism can be opened to perform secondary fixation with the base 1 , thereby improving the stability of the speaker body 5 .

[0045] Existing speakers are generally fixed directly to the wall with bolts, and the installation method is relatively cumbersome. In addition, when the equipment is disassembled for maintenance, the bolts need to be removed before it can be taken down, which delays the maintenance efficiency. Therefore, this solution sets a fixing mechanism, and the base 1 is fixed to the wall by bolts. The shell 2 is inserted into the slot 3, and the motor 26 reverses to drive the shaft 9 to rotate. By squeezing the gas, the insertion rod 15 extends from the inside of the equipment and is inserted into the fixing slot 4, thereby realizing convenient fixation of the equipment and improving the installation and disassembly efficiency of the equipment. Specifically: For the installation of the equipment, first, the base 1 needs to be fixed to the wall by bolts. When the equipment needs to be installed , the shell 2 can be inserted into the slot 3 on the base 1, and then the motor 26 is started, so that the output shaft of the motor 26 drives the gear 27 to reverse, and the gear 27 is meshed with the gear 28, and the shaft 9 is driven to rotate under the action of the one-way bearing. The shaft 9 is connected with the threaded slide plate 12 through the threaded groove 11 on the outer surface, so that the threaded slide plate 12 is displaced backward inside the inner cavity, and the gas inside the inner cavity 10 is squeezed into the inside of the support shell 13, and the sealing plate 14 slidably connected inside the support shell 13 is slid outward, and the insertion rod 15 is pushed out of the shell 2 and inserted into the fixing groove 4 to complete the fixed installation of the equipment.

[0046] Embodiment 2:

[0047] The protection mechanism includes an inner cavity 16 opened on the inner front side of the fixed shaft 8, the rotating shaft 9 extends into the interior of the inner cavity 16, and a thread groove 17 is opened on the outer surface, the outer surface of the thread groove 17 is spirally connected to a thread slide 18, and the thread slide 18 is slidably connected to the inner cavity 16.

[0048] A support shell 21 is fixedly installed between the outer surface of the fixed shaft 8 corresponding to the inner cavity 216 and the outer shell 2. The support shell 219 is connected to the inner cavity 216. A sealing plate 20 is slidably connected inside the support shell 19. A rack 21 is fixedly installed on the upper end of the sealing plate 20. Support members 22 are fixedly installed on both sides of the upper end surface of the rectangular cover 44. A protective plate 23 is rotatably connected between the two groups of support members 22. A tooth 24 is fixedly installed on the lower end of the protective plate 23. The tooth 24 is meshed with the rack 21. There are four groups of support shells 219, sealing plates 20, racks 21, protective plates 23 and teeth 24, which are correspondingly arranged and dispersed in a ring shape. A suction cup 25 is fixedly installed on the rear end surface of the protective plate 23. The suction cup 25 is made of rubber.

[0049] The existing speaker body 5 is generally directly exposed to the outside world. During the transportation process, there is a risk of collision damage and the safety is low. Therefore, this solution sets a protective mechanism. The rotation of the shaft 9 will drive the protective mechanism to operate, and also squeeze the gas inside the device to retract the rack 21 into the interior of the device. At the same time, the protective plate 23 will be deflected to open the protection of the speaker body 5. At the same time, the suction cup 25 on the protective plate 23 will be adsorbed and fixed to the base 1. Secondly, the device is reversed, and the protective plate 23 is combined to form a protective effect on the speaker body 5 while the device is disassembled. Specifically: for equipment protection, when the shaft 9 rotates, the same shaft 9 is spirally connected with the threaded slide plate 2 18 through the threaded groove 2 17 opened on the outer surface, so that the threaded slide plate 2 18 is displaced to the rear end inside the inner cavity 2 16 and the support shell 2 19 is supported. The gas is drawn into the inner cavity 16, and the sealing plate 20 slidably connected in the supporting shell 19 will slide inward, and the rack 21 will be received into the interior of the supporting shell 19, and the teeth 24 on the protective plate 23 will mesh with the rack 21, so that the protective plate 23 in the vertical protection state will be deflected and become horizontal with the base 1, opening the protection state for the speaker body 5, and at the same time, the suction cup 25 will be adsorbed and fixed to the base 1 to enhance the fixing effect. When it is necessary to disassemble the equipment and protect the speaker body 5, the continuous drive motor 26 can be reversed. Since the thread groove 11 and the thread groove 2 17 are both loop grooves on the reciprocating screw, the threaded slide 1 12 and the threaded slide 2 18 will return to their original positions, so that the above-mentioned transmission structure can be reversed, the insertion rod 15 is received into the interior of the outer shell 2, and the protective plate 23 becomes vertical to safely protect the speaker body 5.

[0050] Embodiment 3:

[0051] The transmission mechanism includes a fixed shaft 8 having an outer surface with a toothed disc 29 rotatably connected to the rear side, a motor 26 fixedly mounted on the inner rear end surface of the housing 2, a gear 27 fixedly mounted on the end of the front output shaft of the motor 26, a gear 28 meshing with one side of the gear 27, a rear end of the rotating shaft 9 extending to the interior of the housing 2 and fixedly connected with the gear 2 28, the toothed disc 29 meshing with the gear 1 27, a one-way bearing being arranged inside the gear 2 28, a magnet 1 30 and a magnet 2 31 fixedly mounted on the front end surface of the toothed disc 29, and the magnet 1 30 and the magnet 2 31 being symmetrically arranged.

[0052] The azimuth adjustment mechanism includes a support frame 32 rotatably connected to the outer surface of the fixed shaft 8, two sets of sliding sleeves 33 are fixedly installed on the rear side of the outer surface of the fixed shaft 8, the two sets of sliding sleeves 33 are symmetrically arranged, a sliding rod 35 is slidably connected inside the sliding sleeve 33, a magnet three 34 is fixedly installed on the rear end surface of the sliding rod 35, a connecting piece two 40 is fixedly installed on both sides of the rear end surface of the support frame 32 and the front end surface of the sliding rod 35, a connecting rod one 36 is rotatably connected between the two sets of connecting pieces two 40, and the magnet one 30 and the magnet three 34 are magnetically attracted to each other. Magnet 2 31 and magnet 34 repel each other, a support sleeve 39 is fixedly installed on the rear end surface of one side of the speaker body 5, the rear end of the support platform is slidably connected to the transmission rod 42, a fixed plate 41 is fixedly installed on the rear end of the transmission rod 42, a spring 43 is fixedly installed between the fixed plate 41 and the speaker body 5, a connecting piece 1 37 is fixedly installed on the rear end surface of the fixed plate 41, a connecting rod 2 38 is rotatably connected between the connecting piece 1 37 and the end of the support frame 32, and four groups of azimuth adjustment mechanisms are arranged, and are dispersedly arranged in a ring shape.

[0053] The existing wall-mounted speakers are not easy to adjust the angle of the speakers after installation. Moreover, after the speakers are installed, the speakers will vibrate to a certain extent because they play music. After long-term use, the installation bolts on the speakers may become loose. Therefore, this scheme sets a transmission mechanism and an azimuth adjustment mechanism. The motor 26 can drive the transmission mechanism in the forward rotation, so that the toothed disc 29 carries the magnet 1 30 and the magnet 2 31 to rotate. The magnet 1 30 and the magnet 2 31 are respectively attracted and repelled by the magnet 3 34, so that the support frame 32 is deflected, and then the speaker body 5 is driven to deflect, so as to achieve the purpose of adjusting the angle of the speaker body 5. At the same time, the setting of the spring 43, the transmission rod 42 and the support sleeve 39 can play a buffering and protective effect on the speaker body 5. Specifically: for the angle adjustment of the speaker body 5, the motor 26 can be driven to rotate forward. At this time, under the action of the one-way bearing, the rotating shaft 9 will not rotate, and the gear 1 27 will only drive the toothed disc 29 to rotate. The rotation of the toothed disc 29 will carry the magnet 1 30 and the magnet 2 31 to move. When the symmetry When the magnet 1 30 and the magnet 2 31 are rotated to the horizontal position, the magnet 1 30 magnetically attracts the magnet 34 on the horizontal slide bar 35, and the magnet 34 repels the corresponding magnet 34, thereby causing the two sets of slide bars 35 symmetrically arranged in the horizontal direction to move, one set of slide bars 35 moves backward, and the other set of slide bars 35 symmetrically arranged moves forward. The two sets of slide bars 35 are rotatably connected to the two ends of the support frame 32 through the connecting rod 1 36, thereby driving the support frame 32 to deflect, and the support frame 32 is supported. The support frame 32 is rotatably connected to the fixed plate 41 through the connecting rod 2 38, and the fixed plate 41 is fixedly connected to the speaker body 5 through the support sleeve 39, the transmission rod 42 and the spring 43 assembly, so that the speaker body 5 will be driven to deflect, thereby achieving the purpose of adjusting the angle. When adjustment in the opposite direction is required, the toothed plate 29 can be rotated ninety degrees, and the positions of the magnet 1 30 and the magnet 2 31 can be exchanged to achieve angle adjustment in the opposite direction. The same is true for the angle adjustment in the vertical direction.

[0054] A method for using an adjustable wall-mounted speaker comprises the following steps:

[0055] S1: Fixed installation: The base 1 is fixed to the wall by bolts, the housing 2 is inserted into the slot 3, the motor 26 is reversed to drive the shaft 9 to rotate, and the insertion rod 15 is extended from the inside of the device and inserted into the fixing slot 4 by squeezing the gas, thereby realizing convenient fixing of the device and improving the efficiency of installation and disassembly of the device;

[0056] S2: Equipment protection: The rotation of the shaft 9 will drive the protection mechanism to operate, and also squeeze the gas inside the equipment, so that the rack 21 retracts into the interior of the equipment, and at the same time, the protection plate 23 will deflect, opening the protection of the speaker body 5, and at the same time, the suction cup 25 on the protection plate 23 will be adsorbed and fixed to the base 1. Secondly, the equipment is reversed, and the protection plate 23 is combined to form a protection effect on the speaker body 5 while the equipment is disassembled;

[0057] S3: Azimuth adjustment: The forward rotation of the motor 26 can drive the transmission mechanism, so that the toothed disc 29 carries the magnet 1 30 and the magnet 2 31 to rotate, and the magnet 1 30 and the magnet 2 31 are respectively attracted and repelled by the magnet 3 34, so that the support frame 32 is deflected, and then the speaker body 5 is driven to deflect, so as to achieve the purpose of adjusting the angle of the speaker body 5.

[0058] Instructions for use: For the installation of the equipment, first, the base 1 needs to be fixed to the wall by bolts. When the equipment needs to be installed, the shell 2 can be inserted into the slot 3 on the base 1, and then the motor 26 is started to make the output shaft of the motor 26 drive the gear 27 to reverse, and the gear 27 is meshed with the gear 28. Under the action of the one-way bearing, the shaft 9 is driven to rotate. The shaft 9 is connected with the threaded slide plate 12 through the thread groove 11 on the outer surface, so that the threaded slide plate 12 is displaced backward inside the inner cavity, and the gas inside the inner cavity 10 is squeezed into the inside of the support shell 13, and the sealing plate 14 slidingly connected inside the support shell 13 is slid outward, the insertion rod 15 is pushed out of the shell 2, and inserted into the fixed The fixed installation of the equipment is completed in the fixed groove 4. For equipment protection, when the rotating shaft 9 rotates, the same rotating shaft 9 is connected with the threaded slide plate 18 through the threaded groove 17 opened on the outer surface, so that the threaded slide plate 18 is displaced to the rear end inside the inner cavity 16, and the gas in the support shell 19 is drawn into the inner cavity 16. The sealing plate 20 slidably connected in the support shell 19 will slide inward, and the rack 21 will be received into the interior of the support shell 19, and the teeth 24 on the protective plate 23 will mesh with the rack 21, so that the protective plate 23 in the vertical protection state will be deflected and become horizontal with the base 1, opening the protection state of the speaker body 5, and at the same time, the suction cup 25 will be adsorbed and fixed with the base 1 to strengthen The fixing effect is that when it is necessary to dismantle the equipment and protect the speaker body 5, the motor 26 can be continuously driven to reverse. Since the thread groove 11 and the thread groove 2 17 are both loop grooves on the reciprocating screw, the threaded slide 12 and the threaded slide 2 18 will return to their original positions, so that the above-mentioned transmission structure can be reversed, the insertion rod 15 is retracted into the interior of the shell 2, and the protective plate 23 becomes a vertical state to safely protect the speaker body 5. Secondly, for the angle adjustment of the speaker body 5, the motor 26 can be driven to rotate forward. At this time, under the action of the one-way bearing, the shaft 9 will not rotate, and the gear 1 27 will only drive the toothed disc 29 to rotate. The rotation of the toothed disc 29 will carry the magnet 1 30 and the magnet 2 31 to move. When the symmetrically arranged magnet 1 30 and When magnet 2 31 rotates to the horizontal orientation, magnet 1 30 magnetically attracts magnet 3 34 on the horizontal slide bar 35, and magnet 34 repels corresponding magnet 34, thereby causing two sets of symmetrically arranged slide bars 35 to move horizontally, one set of slide bars 35 moves backward, and the other set of symmetrically arranged slide bars 35 moves forward. Both sets of slide bars 35 are rotationally connected to the two ends of the support frame 32 through connecting rod 1 36, thereby driving the support frame 32 to deflect, and the support frame 32 is rotationally connected to the fixed plate 41 through connecting rod 2 38, and the fixed plate 41 is fixedly connected to the speaker body 5 through the support sleeve 39, the transmission rod 42 and the spring 43 assembly, thereby driving the speaker body 5 to deflect, thereby achieving the purpose of adjusting the angle.When the opposite direction adjustment is required, the toothed disc 29 can be rotated 90 degrees, and the positions of the magnet 1 30 and the magnet 2 31 can be exchanged to achieve the angle adjustment in the opposite direction. The same is true for the angle adjustment in the vertical direction.

[0059] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
