Description

Technical Field

[0001] The present invention relates to the technical field of active sound boxes, and in particular to an active sound box with an anti-fall structure. Background Art

[0002] Active speakers, as audio output devices, have been widely used in various occasions, such as home entertainment, conference presentations, outdoor activities, etc. With the advancement of technology and changes in user needs, active speakers not only need to have high-quality audio output capabilities, but also need to have higher durability and portability. Among them, anti-drop performance has become an aspect that users are increasingly concerned about, especially when used in outdoor activities or complex environments, the anti-drop performance of active speakers is particularly important.

[0003] A Chinese patent with announcement number CN110784787B discloses a Bluetooth speaker with an anti-fall function, including a protective shell, pillars are fixedly connected at the four corners of the lower end of the protective shell, rollers are rotatably connected to the lower ends of the pillars, positioning covers are sleeved on the outer walls of the pillars, a push-pull mechanism is fixedly connected to one side of the protective shell, a cover is clamped on the push-pull mechanism, a protective cover is fixedly connected to the upper end of the other side of the protective shell, and a number of lighting lamps are fixedly connected to the inside of the protective cover. Although the above patent can protect the active speaker, the second compression spring will become fatigued and deformed after long-term use, and the active speaker falls at a large angle, resulting in greater force generated by the tipping, causing vibration damage to the active speaker. Both factors affect the effect of protecting the active speaker.

[0004] The present invention aims to solve the problems existing in the above-mentioned patents. To this end, an active speaker with an anti-fall structure is proposed, which can immediately support and limit a tilted active speaker to prevent the active speaker from falling at too large an angle and causing damage, thereby improving the protection effect. Summary of the invention

[0005] In order to overcome the disadvantages that the second compression spring may become fatigued and deformed after long-term use, and that the force generated by the tipping is greater due to the large angle at which the active speaker falls, causing vibration damage to the active speaker, and both factors affect the protection effect of the active speaker, the present invention provides an active speaker with an anti-fall structure that can immediately support and limit a tipped active speaker to prevent the active speaker from being damaged due to excessively large falling angles, thereby improving the protection effect.

[0006] The present invention is achieved through the following technical approaches: An active speaker with a anti - fall structure includes a hemispherical body and a base fixedly connected to the bottom of the hemispherical body. Folding guide wheels are symmetrically installed on the base. N - shaped rods are fixedly connected to the top of the hemispherical body at equal intervals along the circumference. An active speaker is embedded and fixedly connected in the middle of the top of the hemispherical body. It also includes an arc - shaped support plate, a limit frame, a rotating shaft, a swinging rod, a scroll spring I and a trigger component. Four groups of grooves are evenly spaced along the circumference of the hemispherical body. The number of each group of grooves is two. A rotating shaft is rotatably connected to the upper part of each groove. A swinging rod located in the groove is fixedly sleeved on the rotating shaft. A scroll spring I is connected between the swinging rod and the rotating shaft. An arc - shaped support plate is rotatably sleeved on the N - shaped rod. The four arc - shaped support plates contact each other to form a conical plate. A limit frame is fixedly connected to the inner side of the N - shaped rod to limit the arc - shaped support plate. A trigger component is arranged on the hemispherical body. The trigger component is used to drive the arc - shaped support plate to swing outwards, and the trigger component makes the swinging rod swing out of the groove under the action of the scroll spring I, so that the arc - shaped support plate and the swinging rod support and limit the active speaker during the tipping process.

[0007] Further explanation, the trigger component includes a winding wheel rotatably sleeved on the N - shaped rod. The winding wheel is fixedly connected to the shaft part of the arc - shaped support plate. A pull rope is wound on the winding wheel. U - shaped plates are fixedly connected to the top of the hemispherical body at equal intervals along the circumference. An iron ball is placed in the U - shaped plate. The iron ball is fixedly connected to the tail end of the pull rope to drive the movement of the pull rope. A limit component is arranged between the iron ball and the hemispherical body to limit the swinging rod.

[0008] Further explanation, the limit component includes U - shaped rods fixedly connected to the outer side of the hemispherical body at equal intervals along the circumference. The U - shaped rods correspond to the grooves. Guide grooves are symmetrically opened on the grooves. A limit block is slidably connected between the two guide grooves in each groove. The limit block contacts the swinging rod to limit the swinging rod. A pull wire is connected between the outer sides of the limit blocks on each side. The pull wire is fixedly connected to the iron ball. The pull wire passes through the inner side of the U - shaped rod.

[0009] Further explanation, the active speaker with a anti - fall structure also includes a dust - proof component. The dust - proof component includes rotating rods rotatably connected to the hemispherical body at equal intervals. The heights of the rotating rods on the left and right sides are lower than those of the rotating rods on the front and back sides. A dust - blocking cloth for blocking dust is wound on the rotating rods. The active speaker is located between the four dust - blocking cloths. Four groups of fixing rings are fixedly connected to the inner side of the hemispherical body at equal intervals. The number of each group of fixing rings is two. The rotating rod passes through the fixing ring. A scroll spring II is connected between the fixing ring and the rotating rod. A locking component is arranged between the dust - blocking cloth and the arc - shaped support plate to lock and limit the dust - blocking cloth.

[0010] Further explanation, the locking component includes an iron bar fixedly connected to the top of the dust - blocking cloth. A fixing plate is fixedly connected to the arc - shaped support plate. A magnet magnetically contacting the iron bar is fixedly connected to the fixing plate.

[0011] Further description, the active speaker with a fall-proof structure further includes a buffer block rotatably connected to the swing rod for buffering the swing rod, and a torsion spring is connected between the buffer block and the swing rod.

[0012] Further description, the active speaker with a fall-proof structure further includes a counterweight block fixed to the inner side of the hemisphere.

[0013] Further description, it further includes sponge sleeves symmetrically and fixedly sleeved on the n-shaped rod.

[0014] The significant progress of the present invention lies in: 1. Whenever the device is impacted by an external force, the active speaker, the hemisphere and the base are tilted, so that the iron ball is tilted and separated from the hemisphere. The hemisphere drives the winding wheel to rotate through the pulling rope, and the winding wheel drives the arc-shaped support plate to swing outwards. At the same time, the iron ball drives the limiting block to move upwards through the pulling wire and separates from the swing rod. Due to the action of the scroll spring I, the swing rod swings outwards to the outside of the groove, and the swing rod and the arc-shaped support plate cooperate to support and limit the device, that is, to support and limit the active speaker. Under the action of the swing rod and the arc-shaped support plate, it can prevent the active speaker from falling too much and being damaged, thereby improving the protection effect.

[0015] 2. Under the action of the baffle cloth, whenever the active speaker is not in use, the four baffle cloths cooperate with the arc-shaped support plate to cover the active speaker. The baffle cloth and the arc-shaped support plate block the dust, which can prevent dust from adhering to the active speaker and affecting subsequent use, thereby ensuring the cleanliness of the active speaker and facilitating subsequent use.

[0016] 3. Under the action of the buffer block, whenever the swing rod supports and limits the device, the buffer block can buffer the contact between the swing rod and the ground, and prevent the large impact force generated by the violent contact between the swing rod and the ground from affecting the active speaker, thereby further ensuring the safety of the active speaker during use.

Detailed implementation manners

[0026] First of all, it should be pointed out that in different described embodiments, the same components are provided with the same reference numerals or the same component names. Among them, the disclosure content included in the entire specification can be meaningfully applied to the same components with the same reference numerals or the same component names. The position descriptions selected in the specification, such as up, down, lateral, etc., also refer to the directly described and illustrated drawings and are meaningfully applied to the new positions when the positions change.

[0027] Example: An active speaker with a anti-falling structure, please refer to Figures 1 - 4As shown in the figure, it includes a hemispherical body 1 and a base 2 fixedly connected to the bottom of the hemispherical body 1. Folding guide wheels 3 are symmetrically installed on the left and right sides of the base 2. Four n-shaped rods 4 are fixedly connected to the top of the hemispherical body 1 at equal intervals along the circumference. Sponge sleeves 6 are symmetrically and fixedly sleeved on the upper parts of the n-shaped rods 4. An active speaker 5 is embedded and fixedly connected to the middle of the top of the hemispherical body 1. It also includes an arc-shaped support plate 7, a limit frame 8, a rotating shaft 9, a swinging rod 10, a scroll spring I 11 and a trigger assembly. Four groups of grooves 101 are evenly spaced along the circumference of the hemispherical body 1. The number of grooves 101 in each group is two. A rotating shaft 9 is rotatably connected to the upper part of each groove 101. A swinging rod 10 is fixedly sleeved in the middle of the rotating shaft 9. The swinging rod 10 is located in the groove 101. A scroll spring I 11 is connected between the swinging rod 10 and the rotating shaft 9. The upper parts of the four n-shaped rods 4 are rotatably sleeved with an arc-shaped support plate 7 in the middle. The four arc-shaped support plates 7 are in contact with each other to form a conical plate. Limit frames 8 are fixedly connected to the middle of the inner tops of the four n-shaped rods 4. When the arc-shaped support plate 7 swings outwards and contacts the limit frame 8, the limit frame 8 can limit the arc-shaped support plate 7. A trigger assembly is arranged on the hemispherical body 1. The trigger assembly is used to drive the arc-shaped support plate 7 to swing outwards, and the trigger assembly makes the swinging rod 10 swing outwards to the outside of the groove 101 under the action of the scroll spring I 11, so that the arc-shaped support plate 7 and the swinging rod 10 support and limit the active speaker 5 during the tipping process.

[0028] Please refer to Figure 3 As shown in the figure, the trigger assembly includes a U-shaped plate 12, an iron ball 121, a pull rope 122, a winding wheel 123 and a limit assembly. Winding wheels 123 are rotatably sleeved in the middle of the upper parts of the four n-shaped rods 4. The winding wheels 123 are fixedly connected to the shaft parts of the arc-shaped support plates 7. A pull rope 122 is wound around the winding wheels 123. Four U-shaped plates 12 are fixedly connected to the top of the hemispherical body 1 at equal intervals along the circumference. An iron ball 121 is placed in the U-shaped plate 12. The four iron balls 121 are respectively fixedly connected to the tail ends of the four pull ropes 122. When the iron ball 121 is separated from the hemispherical body 1, the iron ball 121 can drive the pull rope 122 to move. A limit assembly is arranged between the iron ball 121 and the hemispherical body 1. The limit assembly can limit the swinging rod 10; the limit assembly includes a limit block 131, a pull wire 132 and a U-shaped rod 133. Four U-shaped rods 133 are fixedly connected to the upper part of the outer side of the hemispherical body 1 at equal intervals along the circumference. The four U-shaped rods 133 correspond to the four groups of grooves 101 respectively. Guide grooves 13 are symmetrically opened on the grooves 101. A limit block 131 is slidably connected between the two guide grooves 13 in each groove 101. The inner side of the limit block 131 contacts the lower part of the swinging rod 10. The limit block 131 can limit the swinging rod 10. A pull wire 132 is connected between the outer sides of the two limit blocks 131 on each side. The pull wire 132 is fixedly connected to the iron ball 121. The pull wire 132 passes through the inner side of the U-shaped rod 133.

[0029] Initially, the scroll spring I 11 is in a compressed state. First, hold the sponge sleeve 6 and pull the device to move it through the folding guide wheel 3 so that the device moves to the use position. Due to the function of the sponge sleeve 6, the hand can pull the device more stably. Subsequently, push the folding guide wheel 3 to retract, so that the folding guide wheel 3 folds into the base 2. The base 2 contacts the ground to support the device. Then press the active speaker 5 to start, so that the active speaker 5 plays music. When the device is impacted by an external force, the active speaker 5, the hemisphere 1 and the base 2 are toppled. The toppling of the hemisphere 1 drives the iron ball 121, the swing rod 10 and the n-shaped rod 4 to topple. The toppling of the n-shaped rod 4 drives the arc-shaped support plate 7 to topple. The iron ball 121 corresponding to the toppling direction falls from the hemisphere 1 due to the action of gravity. The remaining three hemispheres 1 are blocked by the U-shaped plate 12 and are difficult to fall from the hemisphere 1. The falling of the iron ball 121 corresponding to the toppling direction drives the pull rope 122 to move. The movement of the pull rope 122 drives the winding wheel 123 to rotate. The rotation of the winding wheel 123 drives the arc-shaped support plate 7 to swing outwards and contact the limit frame 8. The limit frame 8 limits the arc-shaped support plate 7. At the same time, the falling of the iron ball 121 drives the pull wire 132 to move. The pull wire 132 drives the limit block 131 to move upwards to the maximum stroke in the guide groove 13 through the U-shaped rod 133. The upward movement of the limit block 131 disengages from the swing rod 10. Due to the action of the scroll spring I 11, the swing rod 10 swings outwards to outside the groove 101. Subsequently, the swing rod 10 and the arc-shaped support plate 7 continue to topple and contact the ground. The swing rod 10 and the arc-shaped support plate 7 support and limit the toppled active speaker 5 through the n-shaped rod 4 and the hemisphere 1 to immediately buffer and protect the active speaker 5. And under the action of the swing rod 10 and the arc-shaped support plate 7, it can prevent the active speaker 5 from falling down at too large an angle and being damaged, thereby improving the protection effect. Subsequently, the operator holds the sponge sleeve 6 and pulls the hemisphere 1 to swing back to its original position through the n-shaped rod 4, which also makes the active speaker 5 swing back to its original position. Then put the iron ball 121 back inside the corresponding U-shaped plate 12. The movement of the iron ball 121 back to its original position relaxes the movement of the pull rope 122 and the pull wire 132. Pull the arc-shaped support plate 7 to swing inwards to its original position and contact the remaining three arc-shaped support plates 7. Then push the swing rod 10 to swing inwards to its original position, and the scroll spring I 11 is compressed. Subsequently, push the limit block 131 to move downwards to its original position to continue to limit the swing rod 10. The reset of the limit block 131 pulls the pull wire 132 to move back to its original position, and the active speaker 5 can be used continuously. And under the action of the four arc-shaped support plates 7, it can block the dripping rainwater to prevent the rainwater from dripping on the top of the active speaker 5 and causing short-circuit damage, thereby ensuring the safety of the use of the active speaker 5. In this way, no matter which direction the active speaker 5 topples from the four sides, the swing rod 10 and the arc-shaped support plate 7 corresponding to the toppling direction can support and limit the active speaker 5. When the active speaker 5 is not in use, turn off the active speaker 5, pick up the device so that the base 2 is disengaged from the ground contact, and then pull out the folding guide wheel 3 from the base 2.Make the folding guide wheel 3 contact the ground, and the device can be pulled to move by the folding guide wheel 3.

[0030] Please refer to Figure 5 and Figure 6 As shown, the active speaker 5 with a fall-proof structure further includes a dust-proof component installed between the hemispherical body 1 and the arc-shaped support plate 7. The dust-proof component includes a rotating rod 14, a fixing ring 141, a scroll spring II 142, a blocking cloth 143 and a locking component. Four rotating rods 14 are rotatably connected at equal intervals on the inner side of the upper part of the hemispherical body 1. The heights of the left and right rotating rods 14 are lower than those of the front and rear rotating rods 14. The middle parts of the four rotating rods 14 are all wound with the blocking cloth 143. The active speaker 5 is located between the four blocking cloths 143. The blocking cloth 143 can block dust to prevent dust from adhering to the active speaker 5 and affecting subsequent use. Four groups of fixing rings 141 are fixedly connected at equal intervals on the inner side of the upper part of the hemispherical body 1. The number of each group of fixing rings 141 is two. The rotating rod 14 passes through the fixing ring 141. A scroll spring II 142 is connected between the fixing ring 141 and the rotating rod 14. A locking component is arranged between the blocking cloth 143 and the arc-shaped support plate 7. The locking component can lock and limit the blocking cloth 143. The locking component includes an iron bar 144, a fixing plate 145 and a magnet 146. Iron bars 144 are fixedly connected to the tops of the four blocking cloths 143. Fixing plates 145 are fixedly connected to the lower parts of the four arc-shaped support plates 7. Magnets 146 are fixedly connected to the sides of the four fixing plates 145 close to each other. The four magnets 146 are in magnetic contact with the four iron bars 144 respectively to lock and limit the blocking cloth 143.

[0031] Initially, the scroll spring II 142 is in a compressed state. When the active speaker 5 moves to the use position, first pull the four iron bars 144 downward to disengage from the magnets 146. Due to the action of the scroll spring II 142, the rotating rod 14 rotates to wind up the blocking cloth 143, so that the blocking cloth 143 moves downward and stops blocking the active speaker 5, and then the active speaker 5 can be used. When the active speaker 5 does not need to be used, pull the four iron bars 144 upward to drive the four blocking cloths 143 to move upward. The upward movement of the blocking cloth 143 drives the rotating rod 14 to rotate in the reverse direction, and the scroll spring II 142 is compressed. When the iron bar 144 moves upward and contacts the magnet 146, the magnet 146 attracts and fixes the iron bar 144 by magnetic force, thus locking the blocking cloth 143. The four blocking cloths 143 and the arc-shaped support plate 7 cooperate to cover the active speaker 5, and the blocking cloth 143 and the arc-shaped support plate 7 block the dust. In this way, it can prevent dust from adhering to the active speaker 5 and affecting subsequent use, so as to ensure the cleanliness of the active speaker 5 and facilitate subsequent use.

[0032] Please refer to Figure 7As shown in the figure, the active speaker 5 with a fall-proof structure further includes a buffer block 15 and a coil spring 151. Buffer blocks 15 are rotatably connected to the lower parts of the adjacent sides of the eight swing rods 10. When the buffer block 15 contacts the ground, the buffer block 15 can buffer the swing rod 10, and a coil spring 151 is connected between the buffer block 15 and the swing rod 10.

[0033] Please refer to Figure 8 As shown in the figure, the active speaker 5 with a fall-proof structure further includes a counterweight 16, and the counterweight 16 is fixedly connected to the middle part inside the hemisphere 1.

[0034] Initially, the coil spring 151 is in a compressed state. When the swing rod 10 swings outwards to the outside of the groove 101, the swing rod 10 drives the buffer block 15 to swing outwards. The buffer block 15 swings outwards to the outside of the groove 101. Due to the action of the coil spring 151, the buffer block 15 swings a certain distance, and then the swing rod 10 drives the buffer block 15 to swing and contact the ground. The swing rod 10 buffers and protects the hemisphere 1 through the buffer block 15, that is, buffers and protects the active speaker 5. At the same time, under the action of the coil spring 151, the buffer block 15 can buffer and protect the swing rod 10. When the swing rod 10 swings inwards to reset, the swing rod 10 drives the buffer block 15 to swing inwards into the groove 101. The buffer block 15 contacts the groove 101, and the groove 101 pushes the buffer block 15 to swing and retract, and the coil spring 151 is compressed. In this way, it can prevent the swing rod 10 from contacting the ground violently and generating a large impact force on the active speaker 5, thereby further ensuring the safety of the active speaker 5 during use.

[0035] When the active speaker 5 is in use, the counterweight 16 can provide gravity to the base 2, which makes the base 2 placed more stably, thereby improving the stability of the device.

[0036] Finally, it is necessary to explain that the above content is only used to help understand the technical solution of the present invention and cannot be construed as a limitation on the protection scope of the present invention; non-essential improvements and adjustments made by those skilled in the art based on the above content of the present invention all fall within the scope required to be protected by the present invention.
