Description

Technical Field

[0001] The present invention belongs to the technical field of wall-mounted speakers, and particularly relates to a wall-mounted speaker. Background Art

[0002] A speaker refers to other sounds except human language and music, including sounds of the natural environment, animal sounds, sounds of machine tools, and various sounds made by human actions, etc. A speaker generally includes a set of components such as a power amplifier, peripheral equipment, mixing console, microphone, and display device, etc. Among them, a speaker is a sound output device, such as speakers and subwoofers, etc. A speaker includes high, low, and mid-range speakers, and there may not necessarily be three speakers. The development history of technology can be divided into four stages: vacuum tube, transistor, integrated circuit, and field effect tube.

[0003] After retrieval, Chinese patent CN218041674U discloses a wall-mounted waterproof speaker, which includes a round box. A placement mechanism is rotatably connected to the outside of the round box, and a protection mechanism is fixedly installed inside the round box; the placement mechanism includes an outer ring rotatably connected to the outside of the round box. One side of the outer ring is fixedly installed with a placement box. The inner side wall of the outer ring is fixedly installed with a toothed ring, and the inner side of the toothed ring is meshed with a gear. One end of the gear is fixedly installed with a rotating column, and the outside of the rotating column is rotatably connected to the inner side wall of the round box. The placement mechanism further includes a limiting column rotatably connected to the inner side wall of the placement box. The beneficial effect of the present invention is that the placement box can be used to place the device for playing the picture, and it is fixed at the position of the fixing plate through the fixed spring and the fixed buckle provided.

[0015] In one example, the positioning block and the positioning groove are movably sleeved together, the mounting rod is threadedly connected to the connecting groove, the driving motor is a motor with a speed reducer, the adjusting block is composed of a hexagonal steel, a cylinder and a hexagonal plate, and the clamping block is made of a metal material.

[0016] In one example, two protective tubes are provided in the mounting box, the rope is movably sleeved with the protective tube, and one end of the connecting rod is fixedly connected to one end of the driving shaft of the driving motor.

[0017] The wall-mounted audio device proposed by the present invention can bring the following beneficial effects:

[0018] 1. For this wall-mounted audio device, first, the mounting box is fixed in a suitable position, and then the audio body is fixed between two positioning frames. At this time, the staff adjusts the position of the adjusting block. After several clamping blocks are movably sleeved with the storage tube, the driving motor is started. The driving shaft of the driving motor can drive the adjusting block to rotate through the connecting rod, so that the rotating adjusting block can drive the storage tube to rotate through the clamping blocks. At this time, the two ropes can be wound and unwound outside the storage tube, so as to facilitate the adjustment of the positions of the two positioning frames. At the same time, after adjusting the height of the audio body, when the positioning frame is on the ground, it is convenient for maintenance personnel to maintain the audio later, reducing the difficulty of maintaining the audio body, thereby improving the maintenance efficiency of the staff.

[0019] 2. For this wall-mounted audio device, after the staff places the mounting box at the position to be fixed, the position of the adjusting block is adjusted so that several clamping blocks can be movably sleeved with the rotating tube. The driving motor is started. At this time, the driving shaft of the driving motor can drive the rotating tube to rotate through the adjusting block. Since there is a rotating belt between the rotating shaft and the rotating tube, the first gear meshes with the two second gears, and the second gear meshes with the third gear, so that the rotating tube can drive the two lead screws to rotate when rotating. The rotating lead screw can drive the screw rod to rotate and move inside the mounting box, thereby adjusting the position of the bolt, so that the bolt rotating out of the mounting box can be threadedly connected to the plate to fix the mounting box in a suitable position.

[0020] 3. The wall-mounted speaker is provided with an adjusting rod. After the staff fix the two positioning frames at the bottom of the adjusting rod, they rotate the adjusting rod to adjust the angle of the speaker body, so that the speaker body can play music in different directions. At the same time, after the top and bottom surfaces of the two nuts are respectively attached to the top and bottom surfaces of the connecting block, the adjusting rod can be limited, so as to prevent the adjusting rod from rotating randomly inside the adjusting block, enabling the speaker body to finely adjust the playing angle in different directions. Since a number of magnets are provided inside both the receiving tube and the rotating tube, when the magnets are magnetically attracted to the clamping blocks, the adjusting block can be prevented from moving randomly. After the positioning block and the positioning groove are movably sleeved together, by rotating the two mounting rods, the two positioning frames can move closer to each other. When one side of the positioning block is attached to one side inside the positioning groove, the two fixing frames can be fixed to the bottom of the adjusting rod. BRIEF DESCRIPTION OF THE DRAWINGS

Between the two positioning frames 2, an audio body 3 is provided. On one side of the positioning frame 2, two protrusions are provided. When the protrusions are movably sleeved with the rectangular grooves, the two positioning frames 2 can be snap-connected together, which is convenient for fixing the audio body 3 in the later stage. Inside the positioning frame 2, a rubber pad is provided, which effectively reduces the vibration generated during the operation of the audio body 3 from being transmitted to the positioning frame 2 and improves the stability of the positioning frame 2. On one side of the positioning frame 2, a number of ventilation holes are provided, which is beneficial to the heat dissipation of the audio body 3 during operation. On the top surface of the installation box 1, two positioning plates 4 are provided. Inside the two positioning plates 4, a storage tube 5 is rotatably installed. At one end of the storage tube 5, a number of card slots are provided, and the number of card slots are equally angularly provided at one end of the storage tube 5. Two ropes 6 are wound around the outside of the storage tube 5. Inside the installation box 1, two protection tubes 30 are provided. The ropes 6 are movably sleeved with the protection tubes 30. The protection tubes 30 can protect the ropes 6 during movement and reduce the wear of the ropes 6. When the storage tube 5 rotates, the two ropes 6 can be retracted and released at the same time, so that the ropes 6 can pull the audio body 3 to move through the connecting components, so that the height of the audio body 3 can be adjusted at any time, which is convenient for reducing the height of the audio body 3 for maintenance in the later stage;

[0035] On the top surface of the installation box 1, there is a driving motor 7. The driving motor 7 is a motor with a speed reducer. A transmission component is arranged inside the storage tube 5. The driving shaft of the driving motor 7 can drive the storage tube 5 to rotate through the transmission component. The transmission component includes a connecting rod 8 rotatably installed inside the storage tube 5. One end of the connecting rod 8 is fixedly connected to one end of the driving shaft of the driving motor 7, so that the driving shaft of the driving motor 7 can drive the connecting rod 8 to rotate. A hexagonal groove is opened at the other end of the connecting rod 8. An adjusting block 9 is movably installed inside the connecting rod 8. The adjusting block 9 is composed of a hexagonal steel, a cylinder and a hexagonal plate. The adjusting block 9 can move inside the connecting rod 8 to facilitate adjusting the positions of several clamping blocks 10. The clamping blocks 10 are made of metal materials. Several clamping blocks 10 are movably sleeved on the storage tube 5. When the driving motor 7 is working, the driving shaft of the driving motor 7 can drive the adjusting block 9 to rotate through the connecting rod 8. The rotating adjusting block 9 can drive the storage tube 5 to rotate through the clamping blocks 10, so that the two ropes 6 can be wound and unwound outside the storage tube 5, thereby adjusting the positions of the two positioning frames 2 at the bottom of the installation box 1 and controlling the height of the audio body 3, enabling maintenance personnel to directly repair the lowered audio body 3. On the top surface of the installation box 1, there is a partition 11. A round hole is opened on one side of the partition 11. The partition 11 is movably sleeved on the storage tube 5. The partition 11 can block the two ropes 6 to prevent the two ropes 6 from being wound together when being stored;

[0036] The connecting component includes a connecting block 12. The connecting block 12 is arranged on the bottom surface of the installation box 1. A threaded hole is opened on the top surface of the connecting block 12. The bottom ends of the two ropes 6 are both connected to the top surface of the connecting block 12, so that the two ropes 6 can pull the connecting block 12 to move when moving, thereby adjusting the position of the connecting block 12 at the bottom of the installation box 1. An adjusting rod 13 is threadedly connected inside the connecting block 12. The outside of the adjusting rod 13 is provided with threads. Two nuts 14 are threadedly connected to the outside of the adjusting rod 13. When the top and bottom surfaces of the two nuts 14 are respectively in contact with the top and bottom surfaces of the connecting block 12, the adjusting rod 13 can be positioned to prevent the adjusting rod 13 from rotating randomly inside the connecting block 12. After the two positioning frames 2 are fixed to the bottom of the adjusting rod 13, by adjusting the angle of the adjusting rod 13 inside the connecting block 12, the orientation of the audio body 3 can be controlled, so that when the audio body 3 plays music, it can play music according to the adjusted direction. When multiple installation boxes 1 are fixed at different positions, at this time, multiple audio bodies 3 can play music in different directions. Listeners can feel the width and depth of the sound through the sounds emitted by different audio bodies 3, thereby creating a more realistic music scene and enhancing the immersive experience of the listeners.

[0037] Since a number of positioning grooves 15 are provided on the outer wall surface of the adjusting rod 13, and two positioning blocks 16 are provided on the top surface of the positioning frame 2. After the positioning blocks 16 and the positioning grooves 15 are movably sleeved together, and one side of the positioning block 16 is attached to one side inside the positioning groove 15, it is convenient to fix the two positioning frames 2 at the bottom of the adjusting rod 13 in the later stage, so as to position and install the two positioning frames 2. A connecting groove 17 is provided on one side of the positioning frame 2. Among them, one positioning frame 2 has a connecting groove 17 opened on the upper side and the other has a connecting groove 17 opened on the lower side.

When rotating, the second gear 24 can drive the lead screw 25 to rotate. At this time, when rotating, the lead screw 25 can drive the screw rod 27 to rotate, so that the screw rod 27 moves inside the installation box 1, thereby adjusting the position of the bolt 29 fixed at one end of the screw rod 27, so that the bolt 29 can move out of the inside of the installation box 1. By connecting the rotating bolt 29 to the wall, the installation box 1 can be fixed at the position to be fixed. Two support plates 28 are provided inside the installation box 1. One side of the support plate 28 is provided with a threaded hole. The screw rod 27 is threadedly connected with the support plate 28. The support plate 28 can support one end of the screw rod 27, so that the screw rod 27 can maintain a horizontal state when moving, avoiding shaking of the screw rod 27 when moving. A plurality of magnets 31 are provided inside both the storage tube 5 and the rotating tube 20. When the magnet 31 is magnetically attracted to the clamping block 10, the clamping block 10 is prevented from moving out of the inside of the storage tube 5 or the rotating tube 20 at will, thereby limiting the adjusting block 9.
