Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically to a bendable loudspeaker mesh adapted to irregularly shaped loudspeakers. Background Technology

[0002] A loudspeaker is both a musical instrument and a device that converts electrical signals into sound. When electronic energy is transferred to the coil, it generates a magnetic field that interacts with the paper disc and causes it to vibrate. As the electronic energy changes, the coil in the loudspeaker also moves, and the air changes due to differences in density, thus producing sound.

[0003] To prevent excessive dust from entering the horn's opening and affecting the normal vibration of the internal structure, a horn mesh needs to be installed at the horn opening for protection. The horn openings of irregularly shaped horns also have different shapes, and traditional horn meshes cannot be adapted to the shape of the horn's opening, nor are they convenient to fold and store.

[0004] Now, a novel bendable speaker mesh adapted to irregularly shaped speakers is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a bendable speaker grille that is compatible with irregularly shaped speakers, so as to solve the problem of inconvenience in folding and storing mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bendable speaker grille adapted to an irregularly shaped speaker, comprising an elastic mesh cover, an elastic band fixed around the outer edge of the elastic mesh cover, a left frame sleeved on the left side of the elastic band, a right frame sleeved on the right side of the elastic band, connecting blocks fixed at the top and bottom of the right side of the left frame and the left side of the right frame, a housing sleeved between the left and right connecting blocks, a second gear disk longitudinally movably connected to the right side of the housing, a first gear disk longitudinally movably connected to the left side of the housing, a worm gear fixed below the first gear disk, a worm movably connected between the front and rear of the lower left corner of the housing, a handle movably connected to the lower left corner of the front end of the housing, and mounting holes provided at the top and bottom of the left side of the left frame and the right side of the right frame.

[0007] As a further technical solution of this utility model, the first gear is meshed with the left side of the second gear, and the worm is meshed with the left side of the worm wheel.

[0008] As a further technical solution of this utility model, the rear of the handle is fixedly connected to the worm gear, and the first gear plate and the second gear plate are respectively fixedly connected to the connecting block.

[0009] As a further technical solution of this utility model, grooves are respectively provided at the upper and lower ends of the left frame and the right frame, and pressure plates are movably hinged inside the grooves. Toothed nails are respectively fixed laterally behind the pressure plates. Slots are respectively provided inside the left frame and the right frame, and two bolts are respectively threaded inside the pressure plates on both sides.

[0010] As a further technical solution of this utility model, the pressure plate flips up and down in the groove, and the groove and the pressure plate are on the same horizontal plane.

[0011] As a further technical solution of this utility model, hidden grooves are respectively provided at the upper and lower parts of the front and rear ends of the left and right frame sides, and a toggle block is movably connected between the front and rear of the hidden groove. The toggle block has a hole inside, and a rope is fixedly connected between the front and rear holes. Two sets of screw holes are respectively provided on the front and rear sides of the left and right frame sides, and a bolt is threaded into the screw hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the bendable speaker mesh adapted to the irregular speaker not only realizes the folding of the speaker mesh and makes it easy to open the speaker mesh, but also prevents the elastic mesh cover from loosening;

[0013] (1) By connecting the housing between the left and right connecting blocks, the front handle is rotated at the upper and lower housings respectively, guiding the worm gear connected behind it to rotate the worm wheel in place in the housing, guiding the worm wheel and the toothed disc connected to its top to push the toothed disc to rotate the toothed disc, so that the toothed disc and the toothed disc rotate in opposite directions, and then the left frame and the right frame are closed in opposite directions between the upper and lower housings to accommodate the speaker mesh. The wider surface of the elastic mesh can also cover the slots of various irregularly shaped speakers for dust protection.

[0014] (2) The pressure plates are hinged to each other in the groove. The pressure plates installed in the upper and lower grooves are flipped in advance. The elastic mesh cover is fixed between the slots of the left frame and the right frame by the elastic band. The pressure plate and elastic band are locked in the groove by the bolts. This makes it easy to disassemble the elastic band and elastic mesh cover and also allows for quick installation. Both the elastic band and the elastic mesh cover are elastic and can deform as the outer frame is folded and unfolded.

[0015] (3) By moving the toggle block between the front and back inside the hidden groove, pull out the toggle block at the opening of the hidden groove on the side of the left frame and the right frame until the object fits against the side of the front and back ends of the elastic mesh cover. Screw the bolt into the screw hole on the surface for reinforcement, and then insert the rope between the holes of the corresponding toggle blocks at the front and back for reinforcement. This can prevent the two sides of the elastic mesh cover from separating from the left frame and the right frame respectively, so as to achieve the purpose of tightening the elastic mesh cover.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 An embodiment of this utility model provides: a bendable speaker mesh adapted to an irregularly shaped speaker, including an elastic mesh cover 4, an elastic band 3 fixed around the outer edge of the elastic mesh cover 4, a left frame 1 sleeved on the left side of the elastic band 3, a right frame 2 sleeved on the right side of the elastic band 3, connecting blocks 12 fixed at the upper and lower positions on the right side of the left frame 1 and the left side of the right frame 2, a housing 11 sleeved between the left and right connecting blocks 12, a gear disk 20 longitudinally movably connected on the right side inside the housing 11, a gear disk 19 longitudinally movably connected on the left side inside the housing 11, a worm gear 21 fixed below the gear disk 19, a worm 18 movably connected between the front and rear of the lower left corner inside the housing 11, a handle 17 movably connected to the lower left of the front end of the housing 11, and mounting holes 7 provided at the upper and lower positions on the left side of the left frame 1 and the right side of the right frame 2.

[0023] Gear 19 is meshed with the left side of gear 20, worm 18 is meshed with the left side of worm wheel 21, and the rear of the handle 17 is fixedly connected to worm 18. Gear 19 and gear 20 are fixedly connected to connecting block 12 respectively.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, rotating the front handle 17 at the upper and lower housings 11 respectively guides the worm gear 18 connected behind it to rotate the worm wheel 21 in place within the housing 11. This guides the worm wheel 21 and the gear disc 19 connected to its top to push the gear disc 20 through the gear disc 19, causing the gear disc 19 and gear disc 20 to rotate in opposite directions. Subsequently, the left frame 1 and the right frame 2 are closed opposite to each other between the upper and lower housings 11 to accommodate the speaker grille.

[0025] The left frame 1 and the right frame 2 are provided with grooves 8 at the top and bottom of the front end, and pressure plates 9 are movably hinged inside the grooves 8. Toothed nails 10 are fixed horizontally behind the pressure plates 9. The left frame 1 and the right frame 2 are provided with slots 16 inside. Bolts 13 are threadedly connected to the inside of both sides of the pressure plates 9. The pressure plates 9 can flip up and down in the grooves 8, and the grooves 8 and the pressure plates 9 are on the same horizontal plane.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, the pressure plate 9, which is installed in the upper and lower grooves 8, is flipped over beforehand. The elastic mesh cover 4 is then fixed between the slots 16 of the left frame 1 and the right frame 2 by the elastic band 3. The pressure plate 9 and the elastic band 3 are locked in the groove 8 by the bolt 2 13. This allows the elastic band 3 and the elastic mesh cover 4 to be removed and installed quickly. It is also very convenient to replace the new elastic mesh cover 4.

[0027] Hidden grooves 14 are provided at the top and bottom of the front and rear ends of the sides of the left frame 1 and the right frame 2, and a toggle block 15 is movably connected between the front and rear of the hidden groove 14. The toggle block 15 has a hole 22 inside, and a rope 23 is fixedly connected between the front and rear holes 22. Two sets of screw holes 5 are provided on the front and rear sides of the left frame 1 and the right frame 2, and a bolt 6 is threaded in the screw hole 5.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, at the opening of the hidden groove 14 on the side of the left frame 1 and the right frame 2, pull out the toggle block 15 until it fits against the sides of the front and rear ends of the elastic mesh cover 4. Screw in the screw hole 5 on the surface with a bolt 6 for reinforcement. Then, insert a rope 23 between the holes 22 of the corresponding toggle blocks 15 at the front and rear ends for reinforcement. This can prevent the two sides of the elastic mesh cover 4 from detaching from the left frame 1 and the right frame 2 respectively.

[0029] Working principle: When using this utility model, first flip the pressure plate 9 that is movably installed in the upper and lower grooves 8. Then, fix the elastic mesh cover 4 between the slots 16 of the left frame 1 and the right frame 2 using the elastic band 3. Lock the pressure plate 9 and the elastic band 3 in the groove 8 with bolt 13. This facilitates the disassembly of the elastic band 3 and the elastic mesh cover 4, and also allows for quick installation. Then, pull out the actuating block 15 from the opening of the hidden groove 14 on the side of the left frame 1 and the right frame 2 until the block is attached to the sides of the front and rear ends of the elastic mesh cover 4. Finally, screw in bolt 6 into the screw hole 5 on the surface for reinforcement. Then, a rope 23 is inserted between the holes 22 of the corresponding front and rear actuating blocks 15 for reinforcement, which can prevent the two sides of the elastic net cover 4 from detaching from the left frame 1 and the right frame 2 respectively. Then, the front handle 17 is rotated at the upper and lower shells 11 respectively, guiding the worm gear 18 connected behind it to rotate the worm wheel 21 in place in the shell 11. The worm wheel 21 and the toothed disc 19 connected to its top are guided to push the toothed disc 20 through the toothed disc 19, so that the toothed disc 19 and the toothed disc 20 rotate in opposite directions, and then the left frame 1 and the right frame 2 are closed in opposite directions between the upper and lower shells 11.
