[0002] In the field of audio equipment, wall-mounted speakers are widely used in living rooms, bedrooms, conference rooms, and small home theaters due to their space-saving advantages and ability to avoid occupying floor space. Currently, most wall-mounted speakers on the market use a fixed installation structure, meaning the speaker body is directly connected to the wall via a bracket or mounting plate. After installation, the speaker's sound direction remains essentially fixed, and the angle cannot be flexibly adjusted according to actual usage needs, which to some extent limits the speaker's applicability.
[0003] As users' demands for audio experience continue to rise, fixed-angle wall-mounted speakers are gradually revealing obvious shortcomings: In home use, when users move around in different positions (such as sofa, dining table, and desk), fixed-directional speakers cannot ensure that each area can obtain uniform and clear sound field coverage; in multi-person use scenarios such as conference rooms, fixed-angle speakers are even less able to meet the listening needs of listeners in different seats, and are prone to problems such as weak sound or sound quality distortion in some areas. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing fixed-direction speakers, which cannot ensure uniform and clear sound field coverage in every area; in multi-user scenarios such as conference rooms, fixed-angle speakers are even less able to meet the auditory needs of listeners in different seats, and are prone to weak sound or sound quality distortion in some areas. Therefore, a wall-mounted speaker device is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A wall-mounted speaker device includes a speaker and a wall mount. The speaker has a mounting groove on its back, and a threaded hole is formed in the inner wall of the mounting groove. The wall mount includes a connecting block fixedly connected to the mounting groove. A rotating arm is rotatably connected to the outer wall of the connecting block. The end of the rotating arm away from the connecting block is connected to a mounting box through a left-right angle adjustment structure. A tilt angle adjustment mechanism is provided below the rotating arm, and the mounting box controls the tilt angle of the speaker through the tilt angle adjustment mechanism.
[0007] Preferably, the left and right angle adjustment structure includes a worm gear rotatably connected to the bottom of the inner wall of the mounting box, a fixed rod fixedly connected to the top of the worm gear, and a worm rotatably connected to the inner wall of the mounting box; the top end of the fixed rod passes through the top of the mounting box and is fixedly connected to the rotating arm, and the worm and the worm gear mesh with each other.
[0008] Preferably, one end of the worm gear passes through the side wall of the mounting box and extends outward, and the extended end has a rectangular hole for inserting a tool to drive its rotation.
[0009] Preferably, the tilt angle adjustment mechanism includes a rotating block rotatably connected to the connecting block, a slide rod fixedly connected to the rotating block, and a sliding sleeve rotatably connected to the outer wall of the mounting box; the slide rod is inserted into the inner wall of the sliding sleeve and can slide along its axial direction.
[0010] Preferably, the slide rod and the slide sleeve are provided with a plurality of corresponding limiting holes spaced apart along the axial direction on their side walls, and the tilt angle adjustment mechanism further includes bolts and nuts that can be inserted into the limiting holes to lock the relative positions of the slide rod and the slide sleeve.
[0011] Preferably, the outer wall of the back plate of the mounting box is fixedly connected with a plurality of bolt sleeves for fixing to the wall, and the back plate of the mounting box is provided with through holes for fasteners to pass through at the position of each bolt sleeve.
[0012] Preferably, the number of bolt sleeves is four, and they are arranged in a rectangular array.
[0013] Preferably, the axis of the worm gear is perpendicular to the axis of the fixed rod.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. In use, this utility model can overcome the limitations of traditional fixed-direction speakers through the combination design of "rotating arm + left and right angle adjustment structure + tilt angle adjustment mechanism": the left and right directions can be precisely adjusted by worm gear drive, and the tilt direction can be flexibly adjusted by the multi-position limit holes of the slide rod and slide sleeve, so as to achieve all-round adaptation of the speaker orientation. It can adjust the sound field coverage for different seats of the audience in multi-person scenarios such as conference rooms, effectively avoid the problem of weak sound or sound quality distortion in some areas, and improve the overall auditory consistency.
[0016] 2. When using this utility model, four rectangular array bolt sleeves and through holes are set on the outer wall of the mounting box.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] Reference Figures 1-4 A wall-mounted speaker device includes a speaker 1 and a wall mount 2. The speaker 1 is preferably made of ABS engineering plastic or 5052 aluminum alloy in one piece, which can reduce the overall weight and adapt to the needs of wall mounting. A mounting groove 3 is provided in the center of the back of the speaker 1. The inner wall of the groove has 3-4 M5 threaded holes 4 evenly provided along the length direction. The depth of the threaded holes 4 is 8-10mm, and the spacing between adjacent threaded holes 4 is 30-35mm, which are used to achieve detachable fixation to the wall mount 2 by means of hexagonal bolts.
[0024] The wall mount 2 includes a connecting block 5 that fits into the mounting groove 3. The connecting block 5 is made of Q235 galvanized steel sheet and its shape is consistent with the inner wall contour of the mounting groove 3 to ensure that there is no loose gap after embedding. The outer walls of the connecting block 5 are symmetrically welded with stainless steel pins with a diameter of 6-8mm. The pins are rotatably connected to one end of the rotating arm 6 through clearance fit, and both ends of the pins are fitted with elastic retaining rings to prevent the pins from falling off during rotation. The rotating arm 6 is also made of Q235 galvanized steel sheet bent into shape (U-shaped cross section). The end away from the connecting block 5 is connected to the mounting box 7 through a left and right angle adjustment structure.
[0025] Below the rotating arm 6, there is also a tilt angle adjustment mechanism 8. The mounting box 7 drives the rotating arm 6 and the speaker 1 to rotate around the pin of the connecting block 5 by extending, retracting and rotating the tilt angle adjustment mechanism 8, thereby realizing the adjustment of the tilt angle of the speaker 1.
[0026] The left and right angle adjustment structure includes: a worm gear 9 rotatably connected to the bottom of the inner wall of the mounting box 7, a fixing rod 10 fixedly connected to the top of the worm gear 9, and a worm 11 rotatably connected to the inner wall of the mounting box 7; wherein, the mounting box 7 is formed by bending and welding cold-rolled steel plate, the bottom of the worm gear 9 has an integrally formed rotating shaft, the rotating shaft is rotatably connected to the bottom of the inner wall of the mounting box 7 through a deep groove ball bearing, the outer ring of the bearing is interference fit with the inner wall of the mounting box 7, and the inner ring is transition fit with the rotating shaft to reduce the coefficient of rotational friction; the bottom of the fixing rod 10 is connected to the keyway at the top of the worm gear 9 through a flat key, and the top is fixed to the end of the rotating arm 6 away from the connecting block 5 by full welding to ensure that the power transmission is slip-free.
[0027] The worm gear 11 is adapted to the worm wheel 9. Its two ends are rotatably connected to the left and right inner walls of the mounting box 7 through tapered roller bearings. The outer ring of the bearing is interference-fitted with the inner wall of the mounting box 7, and the inner ring is transition-fitted with the worm gear 11 to improve the radial load capacity of the worm gear 11. One end of the worm gear 11 passes through the outer wall of the mounting box 7 and has a rectangular hole 12 along the axial direction to accommodate a conventional adjusting wrench. During adjustment, the wrench is inserted into the rectangular hole 12 and rotated. The worm gear 11 drives the worm wheel 9 to rotate through tooth meshing. The worm wheel 9 then drives the rotating arm 6 and the speaker 1 to rotate left and right around the axis of the fixed rod 10 through the fixed rod 10. The adjustment angle range is -60° to +60° (0° with the equipment in a vertical installation state). Because the worm gear structure has a self-locking characteristic, no additional locking parts are needed after adjusting to the target angle to maintain the angle stability.
[0028] The tilt angle adjustment mechanism 8 includes: a rotating block 13 rotatably connected to the connecting block 5, a slide rod 14 fixedly connected to the rotating block 13, and a slide sleeve 15 rotatably connected to the outer wall of the mounting box 7; wherein, the rotating block 13 is made of brass (H62) and has a hole on one side that matches the pin of the connecting block 5, so that rotation is achieved through clearance fit; the slide rod 14 is a stainless steel round rod, one end of which is fixed to the other side of the rotating block 13 by welding, and the other end is inserted into the slide sleeve 15 along the axial direction; the slide sleeve 15 is a stainless steel sleeve, the outer wall of which is fixed to the rotating shaft by welding, and the rotating shaft is rotatably connected to the ear plate on the outer wall of the mounting box 7 through clearance fit.
[0029] Both the slide rod 14 and the slide sleeve 15 have limiting holes 16. The slide rod 14 has 6-7 limiting holes 16 evenly distributed along its length, and the slide sleeve 15 has one corresponding limiting hole 16. M5 bolts and nuts 17 are installed in the limiting holes 16. During adjustment, first loosen the bolts and nuts 17, push the slide rod 14 to slide along the inner wall of the slide sleeve 15, drive the rotating block 13 to rotate around the connecting block 5, and thus make the speaker 1 tilt around the pin of the connecting block 5. When the tilt angle reaches the target value (adjustment range: -15° to +30°, downward tilt is negative, upward tilt is positive), align the limiting holes 16 on the slide rod 14 and the slide sleeve 15, and then tighten the bolts and nuts 17 to fix the slide rod 14 and the slide sleeve 15 relative to each other, thereby locking the tilt angle of the speaker 1.
[0030] The outer wall of the mounting box 7 (the side away from the adjustment structure) is fixedly connected with four bolt sleeves 18 arranged in a rectangular array. The bolt sleeves 18 are made of M10 cylindrical nuts and are fixed to the outer wall of the mounting box 7 by full welding. The four bolt sleeves 18 are located at the four corners of the outer wall of the mounting box 7 to ensure that the force is evenly distributed during installation.
[0031] The outer wall of the mounting box 7 has through holes 19 corresponding to the positions of each bolt sleeve 18. The diameter of the through holes 19 is 11mm (1mm larger than the inner diameter of the bolt sleeve 18) to facilitate the passage of the bolts. During installation, the accessories are selected according to the wall material: M10 expansion bolts (effective anchoring depth ≥55mm) are used for concrete walls, and M10 self-tapping screws with plastic expansion tubes (expansion tube length ≥35mm) are used for brick / plasterboard walls. After the bolts pass through the through holes 19, they are threaded into the bolt sleeves 18 and tightened to firmly fix the mounting box 7 to the wall. Its rated load-bearing capacity is ≥8kg, which meets the installation weight requirements of the speaker 1.
[0032] Working principle:
[0033] First, the device is fixedly installed. The mounting box 7 is placed close to the wall, and the bolts are passed through the 11mm through hole 19 on its outer wall and threaded into the M10 bolt sleeve 18 of the rectangular array on the box wall. Then, the mounting groove 3 on the back of the speaker 1 is aligned with the connecting block 5 of the wall mount 2 and inserted. The hexagonal socket head cap screws are passed through the M5 threaded hole 4 on the inner wall of the mounting groove 3 to achieve detachable fixing of the speaker 1 and the connecting block 5.
[0034] Next, the angle adjustment operation is performed: When adjusting the left and right angles, the conventional adjustment wrench is inserted into the rectangular hole 12 at the end of the worm gear 11 and rotated. The worm gear engages and drives the worm wheel 9 to rotate. The worm wheel, through the fixed rod 10, drives the U-shaped rotating arm 6 and the speaker 1 to rotate around the axis of the fixed rod to -60° to +60°. The angle is stabilized by the self-locking characteristic of the worm gear and worm wheel. When adjusting the tilt angle, the M5 bolt and nut 17 of the slide rod 14 and the slide sleeve 15 are loosened. The slide rod is pushed to slide along the slide sleeve, which drives the rotating block 13 to rotate around the pin of the connecting block 5, so that the speaker 1 is tilted to -15° to +30°. After aligning the limit holes 16 of the two, the bolt and nut 17 are tightened to complete the tilt angle locking.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
