The inner frame 653 is fixedly connected to the inner wall of the base frame 64. An outer frame 652 is located inside the base frame 64 and below the inner frame 653. The ventilation mesh 651 is fixedly connected to the inner wall of the outer frame 652. Fixing boxes 654 are fixedly connected to both sides of the outer frame 652 away from the inner frame 653. A movable plate 657 is slidably connected inside the fixing box 654. A pull rod 655 is fixedly connected to one side of the movable plate 657. A return spring 656 is fixedly connected between the movable plate 657 and the fixing box 654, and around the pull rod 655. A fixing post 658 is fixedly connected to the other side of the movable plate 657. A fixing groove is provided inside the base frame 64 at the position corresponding to the fixing post 658.

[0027] By adopting the above technical solution, the pull rod 655 drives the moving plate 657 to move. The movement of the moving plate 657 drives the fixed column 658 to move and retract into the fixed box 654, compressing the return spring 656. Then, the outer frame 652 is moved and placed inside the bottom support frame 64, making it fit against the side wall of the inner frame 653. Then, the pull rod 655 is released, the return spring 656 loses the external force and returns to its original state, driving the moving plate 657 to move. The movement of the moving plate 657 drives the fixed column 658 to move and insert into the fixed groove. The fixed column 658 can be used to insert and fix the outer frame 652 and the bottom support frame 64, which facilitates the disassembly and assembly of the ventilation net 651. During the subsequent operation of the motor 7, the ventilation net 651 can ensure air circulation inside the bottom support frame 64 and the protective cover 61.

[0029] By adopting the above technical solution, when it is necessary to perform maintenance operations on the motor 7, rotate the fixing nut 62 above the protective cover 61 to move it to the top of the fixing screw 63, then move the protective cover 61 up, and then rotate the fixing nut 62 below the protective cover 61 to move it to fit against the side wall of the protective cover 61, so as to facilitate the lifting and lowering operation of the protective cover 61, thereby facilitating the operator to perform maintenance operations on the motor 7.

[0030] In this embodiment, the pull rod 655 drives the moving plate 657 to move. The movement of the moving plate 657 causes the fixed column 658 to move and retract into the fixed box 654, compressing the return spring 656. Then, the outer frame 652 is moved and placed inside the bottom support frame 64, making it fit against the side wall of the inner frame 653. Then, the pull rod 655 is released, and the return spring 656 returns to its original position without external force, driving the moving plate 657 to move. The movement of the moving plate 657 causes the fixed column 658 to move and insert into the fixed groove. The fixed column 658 can be used to insert and fix the outer frame 652 and the bottom support frame 64, facilitating the disassembly and assembly of the ventilation screen 651. Then, the protective cover 61 is moved to fit against the top of the bottom support frame 64, and one of the fixing nuts 62 is rotated to rotate and move along the fixing screw 63 to fit against the protective cover 652. The top wall of 1, under the action of the bottom support frame 64 and the protective cover 61, can provide protection for the motor 7, preventing dust and other debris from falling onto the motor 7, thus preventing the motor 7 from being contaminated or even damaged, and ensuring the normal service life of the motor 7. During the operation of the motor 7, under the action of the ventilation component 65, the air inside the bottom support frame 64 and the protective cover 61 can be ensured to circulate, preventing the working environment temperature of the motor 7 from being too high, thus ensuring the normal service life of the motor 7. The fixing bracket 2 is installed on the wall at the location where the speaker body 4 is used, and then the speaker body 4 is installed inside the two clip frames 3. Then, the motor 7 drives the lifting mechanism 1 to work. The lifting mechanism 1 moves upward, causing the clip frames 3 to move upward, and the clip frames 3 move upward, causing the speaker body 4 to move upward, which facilitates the installation operation of the speaker body 4.

[0031] Example 2

[0032] The difference between this embodiment and Embodiment 1 is that the anti-touch component 5 includes a contact plate 51, a moving rod 52, a connecting sleeve 53, a connecting spring 54, and a rubber pad 55. The connecting sleeve 53 is fixedly connected to the side wall of the frame 3. The moving rod 52 is slidably connected inside the connecting sleeve 53. The connecting spring 54 is fixedly connected between the moving rod 52 and the connecting sleeve 53. The end of the moving rod 52 away from the connecting sleeve 53 is fixedly connected to the contact plate 51. The rubber pad 55 is fixedly connected below the contact plate 51.

[0033] Specifically, a limiting slider is fixedly connected to one end of the moving rod 52 near the connecting sleeve 53, and a limiting groove is formed on the inner side wall of the connecting sleeve 53 at the position corresponding to the limiting slider.

[0034] By adopting the above technical solution, the moving rod 52 moves and drives the limiting slider to move inside the limiting groove. Under the sliding cooperation of the limiting slider and the limiting groove, the movement of the moving rod 52 can be guided, thereby improving the stability of the movement of the moving rod 52.

[0035] In this embodiment, when maintenance is required on the speaker body 4, the motor 7 drives the lifting mechanism 1. The lifting mechanism 1 moves the frame 3 downward, which in turn moves the speaker body 4 and the contact floor 51 downward. When the contact floor 51 moves and comes into contact with the ground, it moves under the pressure of the ground. Under the action of the rubber pad 55, the contact floor 51 is prevented from colliding with the ground and causing damage. The movement of the contact floor 51 moves the moving rod 52 along the connecting sleeve 53. The moving rod 52 presses the connecting spring 54. Under the action of the contact floor 51, the frame 3 is prevented from directly contacting the ground, thus preventing the impact force from being transmitted to the speaker body 4 and causing damage to the speaker body 4.

[0036] The structure and principle of the lifting mechanism 1, which consists of a housing, lead screw, telescopic rod, push ring, first insert, rotating ring, first annular groove, bushing, slot, second annular groove, steel rope, crossbar, guide wheel, bracket, slider, guide rail, second cavity, driving wheel, driven wheel, track, first locking rod, rotating shaft, external thread, moving sleeve, connecting rod, second locking rod, magnetic block, second insert, and bolt, have been disclosed in a wall-mounted speaker disclosed in Chinese patent application number 202310306033.8. Its working principle is as follows: a housing is fixedly connected to the top surface of the fixed frame 2; a motor 7 is mounted on the end face of the housing; a lead screw is fixedly connected to the output end of the motor 7; and a telescopic rod is fixedly connected to the end face of the motor 7. A push ring is fixedly connected to the other end of the telescopic rod. The ring has a first insert fixed to one end of the push ring. A rotating ring is fitted onto the outer surface of the first insert. A first annular groove is formed on the end face of the rotating ring, and a retaining strip is fixed to the outer surface of the rotating ring. A bushing is slidably fitted onto the outer surface of the retaining strip. A retaining groove and a second annular groove are formed on the inner surface of the bushing, and a steel rope is wound around the outer surface of the bushing. A crossbar and a guide wheel are slidably fitted onto the outer surface of the steel rope. Both ends of the guide wheel are rotatably connected to a bracket. A retaining frame 3 is fixed to the end of the steel rope. The lead screw and the telescopic rod both extend into the housing. The telescopic rod is symmetrically arranged about the lead screw. The push ring and the rotating ring are both engaged with the outer surface of the lead screw. The first insert is fitted into the first annular groove. Both ends of the bushing are rotatably connected to the inner end face of the housing. The retaining groove and the second annular groove are connected. The retaining strip and the retaining groove are connected. The sliding sleeve has a locking strip and a slot that are evenly distributed about the axis of the lead screw. The steel ropes wound around the two ends of the bushing rotate in opposite directions. The crossbar is located at the center of the steel rope and is fixed to the inner surface of the housing. The bracket is fixed to the top surface of the fixed frame, and the bracket and guide wheel are symmetrically arranged about the housing. Both ends of the steel rope pass through the housing and the fixed frame. The lead screw does not have self-locking properties. A guide rail is fixed to the inner top surface of the fixed frame. Slider blocks are fixed to the side walls of the card frame 3, and magnetic blocks are fixed to the contact surfaces of the card frames. A second insert is fixed to the bottom end face of one card frame, and a bolt is engaged with the bottom surface of the other card frame. The second insert is engaged with the first card frame, and the bolt is engaged with the second insert. The end face of the housing and the top wall of the fixed frame are respectively provided with a first cavity and a second cavity. The two cavities are respectively equipped with a driving wheel and a driven wheel rotatably connected to the side walls of the first and second cavities. Tracks are slidably fitted onto the outer surfaces of both the driving and driven wheels. A first locking rod and a rotating shaft are fixed to the end faces of the driving and driven wheels, respectively. An external thread is fixed to the outer surface of the other end of the rotating shaft, and a movable sleeve is fitted onto the outer surface of the external thread. A connecting rod is fixed to the outer surface of the movable sleeve. A second locking rod is fixed to the side wall at the bottom end of the connecting rod. One end of the second cavity is connected to the first cavity, and the other end of the second cavity penetrates the top wall of the fixed frame. The connecting rod is slidably fitted onto the end of the second cavity. The second locking rod is engaged with the side wall of the first locking frame. The first locking rod extends into the bushing and is slidably fitted onto the inner end face of the housing. The first locking rod is also engaged with the end face of the rotating ring.Furthermore, the first locking rods are evenly distributed about the central axis of the drive wheel. The rotating ring drives the driven wheel and the shaft to rotate via the first locking rod, the drive wheel, and the track. In use, the motor 7 is started, causing the motor 7 to drive the lead screw to rotate in the opposite direction, thereby causing the push ring and the rotating ring to move in the opposite direction and drive the bushing to rotate, causing the bushing to rewind the steel rope, thereby gradually shortening the length of both ends of the steel rope, so that the steel rope lifts the frame 3 and the sound body 4 until the top surface of the frame 3 is close to the inner top surface of the fixed frame 2. At this time, the locking strips on the rotating ring move from the locking groove to the first locking rod. The second ring groove transitions, engaging the rotating ring with the first locking rod. As the rotating ring continues to rotate, the lifting of the speaker body 4 is synchronized with the translation of the second locking rod until the locking strip disengages from the groove. At this point, the top surface of one of the locking frames 3 contacts the inner top surface of the fixing frame 2 and stops. Meanwhile, the second locking rod continues to translate and engages with the rear wall of one of the locking frames 3. The second locking rod secures the locking frame 3 to the fixing frame 2, allowing the wall-mounted speaker to automatically lock in place after reaching the designated height. This enables synchronized control of the wall-mounted speaker's lifting and fixing.

[0037] The working principle and usage process of this utility model are as follows: The pull rod 655 drives the moving plate 657 to move. The movement of the moving plate 657 causes the fixed column 658 to move and retract into the fixed box 654, compressing the return spring 656. Then, the outer frame 652 is moved and placed inside the bottom support frame 64, fitting against the side wall of the inner frame 653. The pull rod 655 is then released, and the return spring 656, freed from external force, returns to its original position, driving the moving plate 657 to move. The movement of the moving plate 657 causes the fixed column 658 to move and insert into the fixed groove. The fixed column 658 allows the outer frame 652 to be positioned. 2. The base frame 64 is inserted and fixed to facilitate the disassembly and assembly of the ventilation screen 651. Then, the protective cover 61 is moved to fit against the top of the base frame 64, and one of the fixing nuts 62 is rotated to rotate and move along the fixing screw 63 to fit against the top wall of the protective cover 61. Under the action of the base frame 64 and the protective cover 61, the motor 7 can be protected, preventing dust and other debris from the external environment from falling onto the motor 7, thereby preventing the motor 7 from being contaminated or even damaged, and ensuring the normal service life of the motor 7. During the operation of the motor 7, under the action of the ventilation component 65, it can... To ensure air circulation within the base frame 64 and protective cover 61, and to prevent the operating temperature of the motor 7 from becoming too high, thus guaranteeing the normal service life of the motor 7, the mounting bracket 2 is installed on the wall at the location where the speaker body 4 will be used. The speaker body 4 is then installed inside the two mounting frames 3. The motor 7 then drives the lifting mechanism 1, which moves the mounting frames 3 upwards, facilitating the installation of the speaker body 4. When maintenance is required on the speaker body 4, the motor 7 drives the lifting mechanism 1, which in turn moves the mounting frames 3 upwards. The frame 3 moves down, which in turn moves the speaker body 4 and the ground contact 51 down. When the ground contact 51 moves and comes into contact with the ground, it moves under the pressure of the ground. Under the action of the rubber pad 55, the ground contact 51 can be prevented from bumping against the ground and causing damage to the ground contact 51. The movement of the ground contact 51 causes the moving rod 52 to move along the connecting sleeve 53. The moving rod 52 presses the connecting spring 54. Under the action of the ground contact 51, the frame 3 can be prevented from directly contacting the ground, thereby preventing the impact force generated from being transmitted to the speaker body 4 and causing damage to the speaker body 4.
