Description

Technical Field

[0001] This invention relates to the field of audio protection technology, specifically to a home-use, impact-resistant, electromagnetic interference-proof audio device. Background Technology

[0002] Audio equipment is an electronic device used to play sound. It mainly consists of a sound source, an audio processor, a power amplifier, and speakers. It can convert audio signals into sound, allowing people to hear various music, voices, sound effects, etc. It is widely used in various occasions such as homes, conference rooms, cinemas, stage performances, and public places.

[0003] Currently, most cylindrical home audio equipment suffers from damage when impacted. The impacting object directly contacts the audio equipment, causing it to tip over and resulting in damage and shortening its lifespan. Furthermore, while most cylindrical home audio equipment has holes on its outer surface for sound transmission, these holes easily become clogged with dust over time, affecting sound quality. To address these issues, the inventor proposes a home-use impact-resistant, electromagnetic interference-resistant audio device. Summary of the Invention

[0004] In order to solve the problems of damage to audio equipment during collisions and audio equipment falling over, the purpose of this invention is to provide a home-use impact-resistant and electromagnetic interference-proof audio device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a household anti-collision electromagnetic interference audio device, including a protective mechanism, an audio main body for playing music inside the protective mechanism, a stabilizing mechanism to prevent falling at the bottom of the protective mechanism, and a cleaning mechanism for cleaning the protective net inside the protective mechanism.

[0006] Preferably, the protective mechanism includes a mounting base, on the upper surface of which an elastic protective net is rotatably mounted. The elastic protective net is a hollow cylindrical shape used to protect the speaker body. A locking screw cap is rotatably mounted on the top of the elastic protective net, and the locking screw cap is used to install the elastic protective net.

[0007] Preferably, the outer surfaces of both the top and bottom ends of the speaker body are threaded, the bottom end of the speaker body is threadedly connected to the inside of the cleaning mechanism, and the locking cap is threadedly connected to the top end of the speaker body.

[0008] Preferably, the stabilizing mechanism includes a base, which is detachably mounted on the bottom of the mounting base. The outer surface of the bottom end of the mounting base is threaded for mounting the mounting base and the base. The bottom of the base has an annular groove, and counterweight sand is placed in the annular groove to adjust the center of gravity of the base and increase the speed at which the base returns to an upright position.

[0009] Preferably, a connecting rod is hinged to the top of the base, and a counterweight is fixedly installed at the bottom of the connecting rod. When the base shakes, the counterweight will move relatively independently due to inertia, generating a trend opposite to the overall shaking direction of the base, which helps to offset some of the shaking energy and allows the base to return to the balance position more quickly.

[0010] Preferably, a damping spring telescopic rod is hinged to the bottom of the counterweight, and the bottom end of the damping spring telescopic rod is hinged to the bottom of the counterweight. When the base tilts to one side, the elastic force generated by the stretching or compression of the damping spring telescopic rod hinders the movement of the counterweight. At the same time, the damping force consumes energy, so that the swaying amplitude of the base gradually decreases and stabilizes more quickly.

[0011] Preferably, the cleaning mechanism includes a fixed base, which is fixedly installed on the mounting base, and the bottom end of the speaker body is threadedly connected to the inside of the fixed base. Several striking rods are rotatably installed on the upper surface of the fixed base, and the sides of the striking rods away from the center point of the fixed base are in active contact with the elastic protective net.

[0012] Preferably, the upper surface of the fixed base is in movable contact with a movable ring, and the upper surface of the movable ring is rotatably mounted with a number of rotating bars, the number of which is twice that of the striking rod. The ends of two adjacent rotating bars away from the movable ring are rotatably connected to the striking rod. Electric telescopic rods are symmetrically installed at the top inside the fixed base, and the top end of the electric telescopic rods is fixedly connected to the movable ring.

[0013] Preferably, collection boxes are symmetrically installed at the bottom of the fixing base. A collection port is opened on the top of the side of the two collection boxes that are far apart from each other. A filter screen is provided on the top of the side of the two collection boxes that are close to each other. An installation block is fixedly installed at the end of the two collection boxes that are close to each other. The two opposite installation blocks are movably inserted into the fixing base. Two locking screws are installed on the outer surface of the fixing base, and two installation blocks are threadedly connected to the locking screws and threadedly connected to the inside of the fixing base.

[0014] Preferably, a crossbar is rotatably mounted at the bottom of the fixed base, and fans are fixedly mounted at both ends of the crossbar. A second bevel gear is fixedly mounted on the outer surface of the crossbar. A motor is fixedly mounted at the top of the fixed base, and a first bevel gear is fixedly mounted at the bottom end of the motor output shaft. The first bevel gear and the second bevel gear mesh with each other, and an air inlet slot is provided in the mounting base and connected to the fixed base.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In this invention, a stabilizing mechanism is set up to prevent the device from falling over due to the impact of collisions, which would damage the speaker and extend its service life. Secondly, a cleaning mechanism is set up to clean the elastic protective net, preventing the holes in the elastic protective net from becoming blocked and affecting the sound quality of the speaker.

[0017] 2. In this invention, by setting up a counterweight, a damping spring telescopic rod, an annular groove, and sand, the speed at which the device returns to an upright state is increased, avoiding repeated shaking that could affect the electronic components inside the speaker and thus shorten its lifespan.

[0018] 3. In this invention, a striking rod is used to repeatedly strike the elastic protective net, causing it to vibrate and clean it, thus preventing blockage and ensuring the sound quality of the speaker is not affected. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example: Figure 1-8 As shown, the present invention provides a home-use anti-collision electromagnetic interference-resistant audio device, including a protective mechanism 1. The protective mechanism 1 has an internal audio body 2 for playing various music, voice, and sound effects. The audio body 2 is equipped with electromagnetic interference protection to prevent electromagnetic interference from affecting the audio body 2. The bottom of the protective mechanism 1 has a stabilizing mechanism 3 to prevent the audio body 2 from falling and being damaged. The protective mechanism 1 also has a cleaning mechanism 4 inside to clean the elastic protective net 102 and prevent the holes of the elastic protective net 102 from becoming blocked.

[0031] The protective mechanism 1 includes a mounting base 101. An elastic protective net 102 is rotatably mounted on the upper surface of the mounting base 101. The elastic protective net 102 is a hollow cylindrical shape used to protect the speaker body 2. A locking screw cap 103 is rotatably mounted on the top of the elastic protective net 102. The locking screw cap 103 is used to install the elastic protective net 102 and to protect the speaker body 2. In use, when a collision occurs, the elastic protective net 102 absorbs and disperses the impact force generated by the collision. At the same time, the rotation setting of the elastic protective net 102 deflects the impact force generated by the collision, thereby preventing the impact force generated by the collision from affecting the speaker body 2.

[0032] By adopting the above technical solution, the elastic protective net 102 can protect the speaker body 2.

[0033] The outer surfaces of both the top and bottom ends of the speaker body 2 are threaded. The bottom end of the speaker body 2 is threadedly connected to the inside of the cleaning mechanism 4, and the locking cap 103 is threadedly connected to the top end of the speaker body 2. This is used to install the speaker body 2 and facilitate the disassembly, replacement and maintenance of the speaker body 2.

[0034] By adopting the above technical solution, the screw thread can be used to install the speaker body 2.

[0035] The stabilizing mechanism 3 includes a base 301, which is detachably mounted on the bottom of the mounting base 101. The outer surface of the bottom end of the mounting base 101 is threaded for mounting the mounting base 101 and the base 301. The bottom of the base 301 has an annular groove 305, and counterweight sand is placed in the annular groove 305 to adjust the center of gravity of the base 301 and increase the speed at which the base 301 returns to an upright position. Since the annular groove is a ring-shaped space formed around the center of the bottom of the base 301, the sand is distributed in a ring shape in the annular groove 305. When the base 301 tilts, the sand will flow in the annular groove 305 and transfer from one side to the other, making the stability of the base 301 more balanced in all directions. No matter which direction the base 301 tilts, the sand can play a corresponding counterweight role to help the base 301 return to the balanced position.

[0036] By adopting the above technical solution, the annular groove 305 and the sand can increase the speed at which the base 301 returns to an upright state.

[0037] A connecting rod 302 is hinged to the top of the base 301, and a counterweight 303 is fixedly installed at the bottom of the connecting rod 302. When the base 301 shakes, the counterweight 303 will move relatively independently due to inertia, generating a trend opposite to the overall shaking direction of the base 301, which helps to offset some of the shaking energy and allows the base 301 to return to the balance position more quickly.

[0038] By adopting the above technical solution, the counterweight 303 can increase the speed at which the base 301 returns to an upright state.

[0039] A damping spring telescopic rod 304 is hinged to the bottom of the counterweight 303, and the bottom end of the damping spring telescopic rod 304 is hinged to the bottom of the counterweight 303. When the base 301 tilts to one side, the elastic force generated by the stretching or compression of the damping spring telescopic rod 304 hinders the movement of the counterweight 303. At the same time, the damping force consumes energy, causing the swaying amplitude of the base 301 to gradually decrease and stabilize more quickly, thereby increasing the speed at which the base 301 returns to an upright state. When the counterweight 303 sways, the elastic force of the damping spring telescopic rod 304 helps the counterweight 303 return to its initial position more quickly, thereby driving the base 301 to recover to an upright state more quickly. During the swaying process of the base 301, the elastic potential energy of the damping spring telescopic rod 304 and the kinetic energy of the counterweight 303 are mutually converted, making the movement of the counterweight 303 more regular and directional, and accelerating the recovery speed of the base 301.

[0040] By adopting the above technical solution, the damping spring telescopic rod 304 can increase the speed at which the base 301 returns to the upright state.

[0041] The cleaning mechanism 4 includes a fixed base 401, which is fixedly installed on the mounting base 101. The bottom end of the speaker body 2 is threaded into the fixed base 401. Several tapping rods 403 are rotatably installed on the upper surface of the fixed base 401. The side of the tapping rods 403 away from the center point of the fixed base 401 is in active contact with the elastic protective net 102 to clean the elastic protective net 102. In use, the tapping rods 403 swing and vibrate when they come into contact with the elastic protective net 102, thereby cleaning the elastic protective net 102 and preventing the elastic protective net 102 from becoming blocked, which would affect the sound diffusion of the speaker body 2, causing the high frequencies to become blurry and unclear, lose details, and affect the clarity and layering of the overall sound quality.

[0042] By adopting the above technical solution, the slapping rod 403 can clean the elastic protective net 102.

[0043] The upper surface of the fixed base 401 is in contact with a movable ring 402. Several rotating bars 404 are rotatably mounted on the upper surface of the movable ring 402, and the number of rotating bars 404 is twice that of the striking rod 403. The ends of two adjacent rotating bars 404 away from the movable ring 402 are rotatably connected to the striking rod 403. Electric telescopic rods 405 are symmetrically installed at the top inside the fixed base 401, and the top end of the electric telescopic rods 405 is fixedly connected to the movable ring 402 to drive the striking rod 403 to swing. In use, the electric telescopic rod 405 is opened to move the movable ring 402. The movement of the movable ring 402 drives the rotating bars 404 to swing, and the swing of the rotating bars 404 drives the striking rod 403 to swing, so that the striking rod 403 comes into contact with the elastic protective net 102.

[0044] By adopting the above technical solution, the electric telescopic rod 405 can drive the slapping rod 403 to swing.

[0045] A collection box 406 is symmetrically installed inside the bottom of the fixing base 401. A collection port is opened on the top of the side of the two collection boxes 406 that are far apart from each other. A filter screen is provided on the top of the side of the two collection boxes 406 that are close to each other. An installation block is fixedly installed at the end of the two collection boxes 406 that are close to each other. The two opposite installation blocks are movably inserted into the fixing base 401. Two locking screws 407 are installed on the outer surface of the fixing base 401. Two installation blocks are threadedly connected to the locking screws 407 and are threadedly connected to the inside of the fixing base 401 for installing the collection box 406. When in use, when the locking screws 407 are screwed in, the locking screws 407 and the two installation blocks are threadedly connected to the inside of the fixing base 401, and the installation of the collection box 406 is completed.

[0046] By adopting the above technical solution, the locking screw 407 can be used to install the collection box 406.

[0047] A crossbar 408 is rotatably mounted at the bottom of the fixed base 401. Fans 409 are fixedly mounted at both ends of the crossbar 408. A second bevel gear 412 is fixedly mounted on the outer surface of the crossbar 408. A motor 410 is fixedly mounted at the top of the fixed base 401. A first bevel gear 411 is fixedly mounted at the bottom of the output shaft of the motor 410. The first bevel gear 411 and the second bevel gear 412 mesh with each other. An air inlet slot is provided in the mounting base 101 and is connected to the fixed base 401 to drive the fan 409 to rotate. In use, the motor 410 is turned on to drive the first bevel gear 411 to rotate. The rotation of the first bevel gear 411 drives the second bevel gear 412 to rotate. The rotation of the second bevel gear 412 drives the crossbar 408 to rotate. The rotation of the crossbar 408 drives the fan 409 to rotate. At this time, the suction generated by the rotation of the fan 409 collects the cleaned dust.

[0048] By adopting the above technical solution, the fan 409 is able to collect the cleaned dust.

[0049] Working principle: First, when a collision occurs, the elastic protective net 102 absorbs and disperses the impact force generated by the collision. At the same time, the rotation setting of the elastic protective net 102 deflects the impact force generated by the collision, thereby preventing the impact force generated by the collision from affecting the speaker body 2.

[0050] Secondly, the impact force generated by the collision causes the equipment to shake. At this time, the sand will flow in the annular groove 305 and transfer from one side to the other, adjusting the center of gravity of the base 301 and increasing the speed at which the base 301 returns to the upright position. As the sand flows in the annular groove 305, friction and collision will occur between the sand grains and between the sand and the annular groove 305, which consumes the energy of the swing of the base 301 and plays a damping role, so that the swing amplitude of the base 301 gradually decreases, stops the swing more quickly, and returns to the equilibrium position.

[0051] Then, during the shaking process, the counterweight 303 will move relatively independently due to inertia, generating a tendency opposite to the overall shaking direction of the base 301. This helps to offset some of the shaking energy, allowing the base 301 to return to the equilibrium position more quickly. At the same time, the elasticity of the damping spring telescopic rod 304 helps the counterweight 303 return to the initial position more quickly, thereby driving the base 301 to return to an upright state more quickly. During the shaking process of the base 301, the elastic potential energy of the damping spring telescopic rod 304 and the kinetic energy of the counterweight 303 are mutually converted, making the movement of the counterweight 303 more regular and directional, and accelerating the recovery speed of the base 301.

[0052] Finally, when it is necessary to clean the elastic protective net 102, first turn off the main body of the audio system 2, turn on the motor 410 to drive the first bevel gear 411 to rotate, the rotation of the first bevel gear 411 drives the second bevel gear 412 to rotate, the rotation of the second bevel gear 412 drives the crossbar 408 to rotate, the rotation of the crossbar 408 drives the fan 409 to rotate, then turn on the electric telescopic rod 405 to drive the moving ring 402 to move up and down back and forth, the movement of the moving ring 402 drives the rotating bar 404 to swing, the swing of the rotating bar 404 drives the slapping rod 403 to swing, so that the slapping rod 403 comes into contact with the elastic protective net 102, causing the elastic protective net 102 to vibrate, thereby cleaning the elastic protective net 102. At the same time, the suction generated by the rotation of the fan 409 collects the cleaned dust and stores the dust inside the collection box 406.

[0053] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
