Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically to a loudspeaker grille with an adjustable angle. Background Technology

[0002] There are many types of loudspeakers, which are used to transmit messages. As an efficient one-to-many communication method, loudspeakers are widely used in many fields such as stations, airports, factories, mines, schools, and hotels. The loudspeaker mesh is a mesh structure component installed in front of the loudspeaker, which mainly serves to protect, decorate, and improve sound quality. The protruding loudspeaker mesh can increase the diffraction of sound and make the sound coverage area larger, while the concave loudspeaker mesh can concentrate the sound propagation range and increase the sound penetration.

[0003] A search revealed a utility model patent with publication number CN223007642U, which discloses an adjustable-angle horn bracket system. The system includes a horizontal rotation mechanism, a sliding device, and a pitch adjustment mechanism. The horizontal rotation mechanism includes a base with a rotating disk rotatably mounted on its upper part. The sliding device includes a sliding base plate fixedly mounted above the rotating disk. The upper surface of the sliding base plate has a groove, and a slider matching the groove is also provided. A rotating shaft is rotatably mounted on the upper end of the slider. The pitch mechanism includes a connecting arm and an adjusting bolt, with one end of the connecting arm movably connected to the rotating shaft. This utility model's adjustable-angle horn bracket system, through the combination of horizontal rotation, sliding adjustment, and pitch adjustment, provides users with a comprehensive, multi-angle adjustment solution, greatly improving the practicality and convenience of the horn bracket.

[0004] Although the aforementioned patent provides users with a comprehensive, multi-angle adjustment solution through a combination of horizontal rotation, sliding adjustment, and pitch adjustment, greatly improving the practicality and convenience of the speaker bracket, the speaker angle still requires manual adjustment by the operator, and the adjustment accuracy cannot be precisely controlled. Furthermore, the speaker mesh needs to adopt different concave or convex structures depending on the different needs of use, resulting in the need for frequent disassembly and replacement of the speaker mesh on the outer wall of the speaker.

[0005] Therefore, it is necessary to propose an adjustable-angle speaker grille to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an adjustable-angle horn grille. By adjusting the cooperation between the internal parts of the mechanism, the angle of the horn device itself can be adjusted, and the adjustment angle of the horn device can be precisely controlled. Through the cooperation between the internal parts of the elastic mechanism, the horn grille can be deformed into concave and convex shapes, so that the horn grille can switch between concave and convex shapes during use without frequent replacement of the horn grille. This solves the problem that in the prior art, the horn angle still needs to be manually adjusted by the operator, and the adjustment accuracy cannot be precisely controlled. In addition, the horn grille needs to adopt different concave or convex structures according to different needs during use, which leads to the problem of frequent disassembly and replacement of the horn grille on the outer wall of the horn.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable angle horn mesh, including a horn device, a turntable base rotatably connected to the bottom end of the horn device, adjustment mechanisms installed on both sides of the horn device, and an elastic mechanism slidably connected inside the horn device and mechanically connected to the adjustment mechanisms.

[0008] The adjustment mechanism includes a horn grille, which is threadedly installed on the left side of the horn device.

[0009] The elastic mechanism includes a reciprocating screw, which is rotatably connected to the inside of the horn device. A slide is sleeved on the outer wall of the reciprocating screw and slidably connected to the inside of the horn device. A connecting frame is mechanically fixed to the top of the slide. A connecting rod is rotatably connected to the inner wall of the horn grille and extends through the inside of the connecting frame.

[0010] Preferably, the adjustment mechanism further includes a servo motor, which is fixed to the right side of the horn device by bolts, and a gearbox is installed inside the servo motor. The output end of the servo motor is mechanically connected to a transmission rod through a coupling, and the left side of the transmission rod is mechanically connected to a reciprocating screw. A transmission gear is sleeved and fixed on the outer wall of the transmission rod and rotatably connected to the inside of the horn device. A support gear is installed and fixed on the top of the turntable base and rotatably connected to the inside of the horn device through a bearing, and is located on one side of the bottom end of the transmission gear.

[0011] Preferably, the speaker device has multiple speaker generators arranged in a ring inside and powered by cables. The left side of the speaker device has a threaded groove that matches the speaker grille. The turntable base is fixed to the wall or bracket by bolts.

[0012] Preferably, the transmission gear and the support gear mesh with each other through tooth grooves, the transmission gear is a small gear, the support gear is a large gear, and the inside of the horn device is provided with a transmission groove that matches the transmission gear and the support gear.

[0013] Preferably, the slide block is installed inside the slide block and matches the slide groove on the outer wall of the reciprocating screw. The horn device has a slide groove inside that matches the slide block and the connecting frame. The left side of the reciprocating screw is mechanically fixed with a limit ring.

[0014] Preferably, the top of the connecting frame and the surface of the connecting rod are provided with threaded holes that match the bolts, the surface of the connecting frame is provided with mating grooves that match the connecting rod, and the speaker grille is made of rubber with a honeycomb mesh structure.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By starting the servo motor, the servo motor drives the transmission rod to rotate, the transmission rod rotates the transmission gear, the transmission gear rotates the support gear, and the support gear rotates the turntable base through the bearing. The turntable base then rotates the horn device at the top through the bearing. Since the transmission gear is a small gear and the support gear is a large gear, the transmission gear drives the support gear to rotate slowly, thereby enabling the horn device to complete the angle adjustment and facilitating precise control of the horn device's adjustment angle.

[0017] 2. By bringing the horn grille close to the outer wall of the horn device and fixing the connecting rod to the connecting frame with bolts, the installation and fixation between the horn grille and the horn device are completed by rotating the horn grille and using threads. When the transmission rod rotates, the rotation of the transmission rod drives the reciprocating screw to rotate, which in turn drives the slide to slide back and forth through the threads. The sliding of the slide drives the connecting rod to extend and retract through the connecting frame, causing the connecting rod to stretch or compress the horn grille. At the same time, the horn grille is made of rubber and has a honeycomb mesh structure, which makes the horn grille have a certain degree of elasticity. As a result, the horn grille undergoes concave and convex deformation, changing the shape and structure of the horn grille. This allows the horn grille to meet different usage requirements, thus eliminating the need for frequent replacement of the horn grille. Attached Figure Description

[0026] This utility model provides, for example Figure 1-4 An adjustable angle horn mesh is shown, including a horn device 1, a turntable base 101 rotatably connected to the bottom end of the horn device 1, an adjustment mechanism 2 installed on both sides of the horn device 1, and an elastic mechanism 3 slidably connected inside the horn device 1 and mechanically connected to the adjustment mechanism 2.

[0027] The adjustment mechanism 2 includes a horn grille 205, which is threadedly installed on the left side of the horn device 1;

[0028] The elastic mechanism 3 includes a reciprocating screw 301, which is rotatably connected to the inside of the horn device 1. A slide block 302 is sleeved on the outer wall of the reciprocating screw 301 and slidably connected to the inside of the horn device 1. A connecting frame 303 is mechanically fixed to the top of the slide block 302. A connecting rod 304 is rotatably connected to the inner wall of the horn grille 205 and extends through the inside of the connecting frame 303.

[0029] By adjusting the cooperation between the internal parts of the adjustment mechanism 2, the angle of the speaker device 1 can be adjusted, and the adjustment angle of the speaker device 1 can be precisely controlled. By adjusting the cooperation between the internal parts of the elastic mechanism 3, the speaker grille 205 can be deformed into concave and convex shapes, so that the speaker grille 205 can meet the concave and convex switching during use, without the need to frequently replace the speaker grille 205.

[0030] Refer to the instruction manual appendix Figure 1-4The adjustment mechanism 2 also includes a servo motor 201, which is fixed to the right side of the horn device 1 by bolts. A gearbox is installed inside the servo motor 201. The output end of the servo motor 201 is mechanically connected to a transmission rod 202 through a coupling. The left side of the transmission rod 202 is mechanically connected to a reciprocating screw 301. A transmission gear 203 is sleeved and fixed on the outer wall of the transmission rod 202 and rotatably connected to the inside of the horn device 1. A support gear 204 is installed and fixed on the top of the turntable base 101 and rotatably connected to the inside of the horn device 1 through a bearing. It is located on one side of the bottom end of the transmission gear 203. By cooperating with each other, the adjustment angle of the horn device 1 can be precisely controlled.

[0031] Refer to the instruction manual appendix Figure 1-4 The speaker device 1 has multiple speaker generators arranged in a ring inside and powered by cables. The left side of the speaker device 1 has a threaded groove that matches the speaker grille 205. The turntable base 101 is fixed to the wall or bracket by bolts. The threaded groove on the left side of the speaker device 1 that matches the speaker grille 205 facilitates the connection between the speaker grille 205 and the speaker device 1.

[0032] Refer to the instruction manual appendix Figure 1-4 The transmission gear 203 and the support gear 204 mesh with each other through tooth grooves. The transmission gear 203 is a small gear and the support gear 204 is a large gear. The inside of the horn device 1 is provided with a transmission groove that matches the transmission gear 203 and the support gear 204. The transmission gear 203 and the support gear 204 mesh with each other through tooth grooves. The transmission gear 203 is a small gear and the support gear 204 is a large gear. This makes it easy for the transmission gear 203 to drive the support gear 204 to rotate slowly, and makes it easy to accurately control the adjustment angle of the horn device 1.

[0033] Refer to the instruction manual appendix Figure 1-4 The slide block 302 is equipped with a slider that matches the slide groove on the outer wall of the reciprocating screw 301. The horn device 1 has a slide groove that matches the slide block 302 and the connecting frame 303. The left side of the reciprocating screw 301 is mechanically fixed with a limit ring. The slide block 302 slides back and forth on the outer wall of the reciprocating screw 301.

[0034] Refer to the instruction manual appendix Figure 1-4The top of the connecting bracket 303 and the surface of the connecting rod 304 are provided with threaded holes that match the bolts. The surface of the connecting bracket 303 is provided with mating grooves that match the connecting rod 304. The speaker grille 205 is made of rubber and has a honeycomb mesh structure. The fact that the speaker grille 205 is made of rubber and has a honeycomb mesh structure makes it easy for the speaker grille 205 to have a certain degree of elasticity and to undergo concave and convex deformation.

[0035] The working principle of this practical application is as follows:

[0036] Refer to the instruction manual appendix Figure 1-4 By starting the servo motor 201, the servo motor 201 drives the transmission rod 202 to rotate. The rotation of the transmission rod 202 drives the transmission gear 203 to rotate. The rotation of the transmission gear 203 drives the support gear 204 to rotate. The rotation of the support gear 204 drives the turntable base 101 to rotate through the bearing. This causes the turntable base 101 to drive the horn device 1 at the top to rotate through the bearing. Since the transmission gear 203 is a small gear and the support gear 204 is a large gear, it is easy for the transmission gear 203 to drive the support gear 204 to rotate slowly, thereby enabling the horn device 1 to complete the angle adjustment, which is convenient for precise control of the adjustment angle of the horn device 1.

[0037] Refer to the instruction manual appendix Figure 1-4 By bringing the horn grille 205 close to the outer wall of the horn device 1 and fixing the connecting rod 304 and the connecting frame 303 together with bolts, the horn grille 205 is rotated, and the installation and fixation between the horn grille 205 and the horn device 1 is completed by threads. When the transmission rod 202 rotates, the transmission rod 202 rotates and drives the reciprocating screw 301 to rotate, so that the reciprocating screw 301 rotates and drives the slide 302 to slide back and forth through the threads. The reciprocating sliding of the slide 302 drives the connecting rod 304 to move telescopically through the connecting frame 303, so that the connecting rod 304 moves back and forth to stretch or compress the horn grille 205. At the same time, the horn grille 205 is made of rubber and the mesh structure is honeycomb, which makes the horn grille 205 have a certain degree of elasticity. Thus, the horn grille 205 undergoes concave and convex deformation, so that the shape structure of the horn grille 205 can be changed, so that the horn grille 205 can meet different usage requirements, thereby eliminating the need for frequent replacement of the horn grille 205.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
