DETAILED DESCRIPTION

[0020] The present application will be further described below in conjunction with examples.

[0021] Example 1: As Figures 1 to 6 ​As shown, a suspension resonance suppression type sound device includes a sound device body 1, a two-stage constraint mechanism 2 is arranged on the sound device body 1, the two-stage constraint mechanism 2 includes: The constraint assembly one includes two hole plates 21, the upper and lower ends of the two hole plates 21 are provided with positioning holes, and the positioning holes at the upper and lower ends of the hole plates 21 are used for penetrating rivets, which are not shown in the figure for convenient display. The rivets are fastened to the wall surface. And the side of the hole plate 21 close to the sound device body 1 is provided with a constraint hole 22, the constraint hole 22 is distributed in multiple on the hole plate 21 from top to bottom, and the two constraint holes 22 at the same height are both threadedly connected with a constraint bolt 23; The end of the constraint bolt 23 away from the hole plate 21 is provided with an adjusting assembly 4, and the adjusting assembly 4 is provided with a constraint rope 24, which is made of steel woven rope or ultra-high molecular weight polyethylene fiber rope. The rope body is tightly wound in a spiral direction by a plurality of steel wire ropes to form a nonlinear distribution mode. The geometric nonlinear friction and wave scattering effect is used to realize efficient dissipation of vibration energy, reduce and reduce vibration transmission; The end of the constraint rope 24 away from the hole plate 21 is detachably connected with the sound device body 1 through the connecting assembly 3; The constraint assembly two includes a damping rotating shaft 25 rotatably connected between the bottoms of the two hole plates 21 through a damping structure, the outer wall of the middle part of the damping rotating shaft 25 is fixedly connected with an extension plate 27, and the end of the extension plate 27 away from the damping rotating shaft 25 is fixedly provided with an adaptive supporting plate 28. Specifically, the top surface of the adaptive supporting plate 28 is provided with a first groove, and an energy absorption plate one 281 is slidably connected in the first groove. The two ends of the adaptive supporting plate 28 are symmetrically fixedly connected with adaptive protective plates 29, and the positions corresponding to the adaptive supporting plate 28 and the adaptive protective plates 29 on the sound device body 1 are provided with inner grooves. The adaptive supporting plate 28, the adaptive protective plates 29 and the inner grooves are connected in a clamping manner. The sound device body 1 is limited by the clamping connection of the inner grooves and the two, to prevent sliding or displacement. Specifically, the side of the adaptive protective plates 29 close to each other is provided with a second groove, and an energy absorption plate two 291 is slidably connected in the second groove. The energy absorption plate one 281 and the bottom groove surface of the first groove, and the energy absorption plate two 291 and the lateral groove surface of the second groove are respectively connected with buffer springs 210; The buffer springs 210 are arranged in a rectangular array between the energy absorption plate one 281 and the first groove, and between the energy absorption plate two 291 and the second groove. The buffer springs 210 arranged in a rectangular array can more evenly buffer the vibration generated by the sound device body 1 during work.

[0022] Specifically, the energy absorption plate one 281 and the energy absorption plate two 291 are made of polyurethane foaming material or EVA foaming material, which has high buffering and energy absorption efficiency and is convenient to process.

[0023] Specifically, the damping structure includes annular friction plates sleeved on both ends of the damping shaft 25, and axial holes opened on the bottom of the two perforated plates 21 and corresponding to the ends of the damping shaft 25. The ends of the damping shaft 25 are interference fit with the axial holes through the annular friction plates. Specifically, the friction force of the damping structure at both ends of the damping shaft 25 is much greater than the gravity of the speaker body 1. That is, when the speaker body 1 is placed on the extension plate 27 and the adapter support plate 28, the damping shaft 25 will not rotate under the action of the damping structure. The annular friction plate is made of ceramic fiber, and the surface that fits the shaft hole wall is frosted to ensure a good damping effect.

[0024] Furthermore, a hexagonal bolt 26 is threadedly connected to one end of the damping shaft 25, and a hexagonal hole 261 is provided on the perforated plate 21 corresponding to the hexagonal bolt 26. The end of the hexagonal bolt 26 away from the damping shaft 25 is adapted to be engaged with the hexagonal hole 261, and the damping shaft 25 is fastened by the hexagonal bolt 26 and the hexagonal hole 261 to further ensure the stability of the damping shaft 25, the extension plate 27, the adapter support plate 28 and the audio body 1.

[0025] When in use: First, the staff places the two perforated plates 21 in parallel, inserts rivets through the positioning holes at the upper and lower ends, embeds the rivets into the wall and tightens them, so that the perforated plates 21 form a fixed connection with the wall, which serves as a fixed basis for hanging the audio body 1.

[0026] Then, based on the required hanging height of the speaker body 1, a restraining hole 22 at the same height is selected on the same side of the perforated plate 21. A restraining bolt 23 is threaded into the restraining hole 22. The release length of the restraining rope 24 is adjusted using the adjustment assembly 4. The other end of the restraining rope 24 is fastened to the speaker body 1 via the connecting assembly 3, completing the upper suspension restraint. Note: The detailed principles of the connecting assembly 3 and the adjusting assembly 4 will be described in the subsequent Examples 2 and 3, respectively.

[0027] When the bottom of the speaker body 1 is placed on the energy absorbing plate 1 281 of the adapter support plate 28, and the two sides are fitted with the energy absorbing plate 2 291 of the adapter guard plate 29, under the action of the gravity of the speaker body 1, the four restraint ropes 24 are always stretched straight. At the same time, the adapter support plate 28 and the adapter guard plate 29 form constraints on the bottom and sides of the speaker body 1 to prevent the speaker body 1 from sliding down or shifting left and right. The overall installation of the speaker body 1 is now completed.

[0028] The vibration generated by the sound body 1 is transmitted to the upper restraint rope 24, and the flexible characteristics of the restraint rope 24 replace the traditional rigid support to avoid direct "rigid transmission" of the vibration to the perforated plate 21, thereby reducing the direct conduction of the vibration to the wall surface; and the perforated plate 21 is connected with the wall surface through rivets, and only a small amount of vibration transmitted to the perforated plate 21 is dispersed to a large area of the wall. The vibration at the bottom of the sound body 1 drives the energy-absorbing plate one 281 and the energy-absorbing plate two 291 to slide in the first groove and the second groove respectively, and extrudes the buffer spring 210 arranged in a rectangular array; the spring absorbs vibration energy through elastic deformation, converts kinetic energy of the vibration into elastic potential energy, and reduces the energy transmitted outward.

[0029] Embodiment two: As shown in Figure 1 , Figures 6 to 8 , the suspension resonance suppression type sound also includes a connecting assembly 3, which includes four boxes 31 fixedly arranged at the four corners of the back of the sound body 1. The top of each box 31 is provided with an opening, and a sliding cover 32 is slidingly connected to the position corresponding to the opening. A carabiner plate 33 is fixedly arranged in the inner cavity of the box 31 close to the side surface of the sound body 1. A lobster buckle 34 is snap-connected to the carabiner plate 33. A swivel ring 341 is sleeved to the end of the lobster buckle 34 away from the carabiner plate 33. The swivel ring 341 is fixedly connected to the end of the restraint rope 24. The box 31 is provided with an opening slot 35 through which the restraint rope 24 passes.

[0030] Further, an opening sliding block 36 is slidingly arranged in the opening slot 35. The two side outer walls of the opening sliding block 36 are provided with spherical protrusions which are slidingly arranged in the opening slot 35. A through hole is formed in the middle of the opening sliding block 36 for the restraint rope 24 to pass through. The function of the through hole is to avoid friction between the restraint rope 24 and the sound body 1, thereby preventing friction damage.

[0031] In use: After the sliding cover 32 is slid open along the opening at the top of the box 31, the lobster buckle 34 can be snap-connected or detached with the carabiner plate 33 to realize quick connection / separation of the restraint rope 24 and the sound body 1. The swivel ring 341 is sleeved to the end of the lobster buckle 34, so that the restraint rope 24 can rotate relative to the lobster buckle 34, thereby facilitating adaptive rotation of the restraint rope 24 during installation of the sound body 1.

[0032] Embodiment three: As shown in Figure 1 , Figures 9 to 11As shown in the figure, the above suspension resonance type sounder further comprises an adjusting assembly 4, which comprises a frame-shaped plate 41 fixedly connected to the end of the restraint bolt 23, the side of the frame-shaped plate 41 away from the restraint bolt 23 is provided with a through slot 42 for the restraint rope 24 to pass through, and the frame-shaped plate 41 is rotatably connected with an adjusting rod 43, the adjusting rod 43 is fixedly provided with a take-up reel 44, and the restraint rope 24 is wound on the take-up reel 44, that is, the part of the restraint rope 24 away from the end of the swivel ring 341 is wound on the take-up reel 44, and the end of the wound part is fixedly connected with the take-up reel 44. The adjusting rod 43 is fixedly connected with a ratchet disc 45 on the outside of the take-up reel 44, and the frame-shaped plate 41 is fixedly provided with a slot plate 46 on the side of the ratchet disc 45. The slot plate 46 is internally slidably connected with a slot block 47, and the slot plate 46 is a slot body structure similar to a cross shape with an open top and an open side edge, the slot block 47 is adapted to slide in the slot plate 46 and ensures that the slot plate 46 can only slide and displace in the horizontal direction. The top of the slot block 47 is provided with a tab for easy manual operation to drive the slot block 47 to translate in the slot plate 46. The bottom of the slot block 47 is rotatably connected with a pawl 48, and the pawl 48 is engagedly connected with the ratchet disc 45. Specifically, the ratchet disc 45 and the pawl 48 constitute a ratchet and pawl one-way rotation structure, wherein the part of the pawl 48 rotatably connected with the slot block 47 is provided with a torsion spring, and as shown in the figure, when the ratchet disc 45 rotates clockwise, the torsion spring is deformed under force, and at the same time, the pawl 48 can be deflected and not engaged with the teeth on the ratchet disc 45 after deflection. Conversely, when the ratchet disc 45 rotates counterclockwise, the pawl 48 is blocked by the side baffle of the slot block 47 and cannot rotate, thereby limiting the reverse rotation of the ratchet disc 45. Note that the torsion spring and the baffle are not marked in the figure, but can be known from the description. Figure 11 When the ratchet disc 45 rotates clockwise, the torsion spring is deformed under force, and at the same time, the pawl 48 can be deflected and not engaged with the teeth on the ratchet disc 45 after deflection. Conversely, when the ratchet disc 45 rotates counterclockwise, the pawl 48 is blocked by the side baffle of the slot block 47 and cannot rotate, thereby limiting the reverse rotation of the ratchet disc 45. Note that the torsion spring and the baffle are not marked in the figure, but can be known from the description. Figure 11 It can be known that the horizontal spring 49 is fixedly connected between the side wall of the slot block 47 and the slot surface of the slot plate 46.

[0033] In use: when it is necessary to adjust the inclination angle of the sounder main body 1, the damping shaft 25 can be first rotated by force to adjust the angle of the adaptive supporting plate 28 and the adaptive supporting plate 29, and then the angle of the sounder main body 1 is adjusted. Then, the staff rotates the adjusting rod 43 to drive the take-up reel 44 to rotate clockwise, the restraint rope 24 is wound and tightened, and the adjustment of the suspension angle of the sounder main body 1 is realized. At this time, the ratchet disc 45 rotates clockwise with the adjusting rod 43, the pawl 48 is deflected by the torsion spring and does not hinder the rotation. If part of the restraint rope 24 needs to be released, the tab at the top of the slot block 47 is held by hand, the horizontal spring 49 is compressed to make the slot block 47 translate, the pawl 48 is separated from the teeth of the ratchet disc 45, and the adjusting rod 43 can be reversely rotated to release the restraint rope 24.
