Description

Technical Field

[0001] The present invention relates to the technical field of sound protection, in particular to a household anti-collision and anti-electromagnetic interference sound device. Background Art

[0002] Audio equipment is an electronic device used to play sound. It is mainly composed of sound source, audio processor, power amplifier and speaker. 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, public places, etc.

[0003] At present, when most cylindrical home audio devices are in use, when they are hit, the collision object and the audio device are in direct contact, so that the force generated by the collision directly acts on the audio device, causing the audio device to fall, resulting in damage to the audio device, and affecting the service life of the audio device. Secondly, most cylindrical home audio devices have holes on the outer surface to facilitate the transmission of sound, but during long-term use, the holes are easily clogged with dust, affecting the sound quality of the audio device. In response to the above problems, the inventors propose a household anti-collision and anti-electromagnetic interference audio device to solve the above problems. Summary of the Invention

[0009] Preferably, a connecting rod is hingedly installed at the top of the base, and a counterweight is fixedly installed at the bottom of the connecting rod.

[0014] Preferably, a cross bar is rotatably installed at the bottom of the fixed seat, fans are fixedly installed at both ends of the cross bar, a second bevel gear is fixedly installed on the outer surface of the cross bar, a motor is fixedly installed at the top of the fixed seat, a first bevel gear is fixedly installed at the bottom end of the motor output shaft, the first bevel gear and the second bevel gear are meshed with each other, and an air inlet slot is opened in the mounting seat and connected to the fixed seat.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, a stabilizing mechanism is provided to prevent the device from falling due to the impact of a collision, which would damage the speaker and extend the service life of the speaker. Secondly, a cleaning mechanism is provided to clean the elastic protective net to prevent the holes in the elastic protective net from being clogged, which would affect the sound quality of the speaker.

[0017] 2. The present invention provides a counterweight, a damping spring telescopic rod, an annular groove and sand to increase the speed at which the device returns to an upright state, thereby preventing repeated shaking from affecting the electronic components inside the speaker and shortening its service life.

[0018] 3. In the present invention, a beating rod is provided to beat the elastic protective net back and forth, so that the elastic protective net is vibrated and cleaned, thereby avoiding clogging of the elastic protective net and affecting the sound quality of the main body of the speaker.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example: Figure 1-8 As shown, the present invention provides a household anti-collision and anti-electromagnetic interference audio device, including a protective mechanism 1, an audio body 2 for playing is provided inside the protective mechanism 1, which is used to play various music, voices and sound effects, and the audio body 2 is provided with anti-electromagnetic interference to avoid electromagnetic interference on the audio body 2. A stabilizing mechanism 3 is provided at the bottom of the protective mechanism 1 to prevent falling, which is used to prevent the audio body 2 from falling and causing damage to the audio body 2. A cleaning mechanism 4 is provided inside the protective mechanism 1 to clean the protective net, which is used to clean the elastic protective net 102 to avoid clogging of the holes in the elastic protective net 102.

[0031] The protective mechanism 1 includes a mounting base 101, on the upper surface of which an elastic protective net 102 is rotatably mounted, and the elastic protective net 102 is hollow cylindrical and used to protect the audio body 2, and a locking screw cover 103 is rotatably mounted on the top of the elastic protective net 102, and the locking screw cover 103 is used to install the elastic protective net 102 to protect the audio body 2. During use, when a collision occurs, the impact force generated by the collision is absorbed and dispersed by the elastic protective net 102, and the impact force generated by the collision is deflected by the rotation setting of the elastic protective net 102, thereby avoiding the impact force generated by the collision from affecting the audio body 2.

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

[0033] The outer surfaces of the upper and lower ends of the speaker body 2 are provided with threads. The bottom end of the speaker body 2 is threadedly connected to the inside of the cleaning mechanism 4, and the locking screw cover 103 is threadedly connected to the top end of the speaker body 2, which is used to install the speaker body 2 and facilitate 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, and the base 301 is detachably mounted on the bottom of the mounting base 101. The outer surface of the bottom end of the mounting base 101 is located on a thread for mounting between the mounting base 101 and the base 301. A circular groove 305 is provided in the bottom of the base 301, and counterweight sand is placed in the circular 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 state. Since the annular groove is an annular space formed around the bottom center of the base 301, the sand is distributed in a ring shape in the circular groove 305. When the base 301 is tilted, the sand will flow in the circular groove 305 and transfer from one side to the other, so that the stability of the base 301 in all directions is more balanced. No matter which direction the base 301 tilts, the sand can play a corresponding counterweight role to help the base 301 return to a 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 the upright state.

[0037] A connecting rod 302 is hingedly installed at the top of the base 301, and a counterweight block 303 is fixedly installed at the bottom of the connecting rod 302. When the base 301 shakes, the counterweight block 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 part of the shaking energy and allow the base 301 to return to a balanced position faster.

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

[0039] The bottom of the counterweight 303 is hingedly installed with a damping spring telescopic rod 304, and the bottom end of the damping spring telescopic rod 304 is hingedly connected 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 shaking amplitude of the base 301 to gradually decrease and stabilize faster, which is used to increase the speed at which the base 301 returns to an upright state. When the counterweight 303 shakes, the elastic force of the damping spring telescopic rod 304 can help the counterweight 303 return to its initial position faster, thereby driving the base 301 as a whole to return to an upright state faster. 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 converted into each other, making the movement of the counterweight 303 more regular and directional, thereby 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 fixing seat 401, which is fixedly mounted on the mounting seat 101, and the bottom end of the speaker body 2 is threadedly connected to the inside of the fixing seat 401. A number of beating rods 403 are rotatably mounted on the upper surface of the fixing seat 401, and the beating rods 403 are in active contact with the elastic protective net 102 on the side away from the center point of the fixing seat 401, so as to clean the elastic protective net 102. When in use, the beating rods 403 swing, and when the beating rods 403 contact the elastic protective net 102, the elastic protective net 102 vibrates, thereby cleaning the elastic protective net 102 and avoiding the elastic protective net 102 from being blocked, which affects the diffusion of the sound of the speaker body 2, causing the treble part to become blurred and the details to be lost, affecting the clarity and layering of the overall sound quality.

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

[0043] The upper surface of the fixed seat 401 is in movable contact with a moving ring 402, and a number of rotating bars 404 are rotatably installed on the upper surface of the moving ring 402, and the number of rotating bars 404 is twice that of the beating rod 403. Two adjacent rotating bars 404 are rotatably connected to the beating rod 403 at one end away from the moving ring 402, and an electric telescopic rod 405 is symmetrically installed on the top of the fixed seat 401, and the top of the electric telescopic rod 405 is fixedly connected to the moving ring 402, which is used to drive the beating rod 403 to swing. When in use, the electric telescopic rod 405 is turned on to drive the moving ring 402 to move, and the movement of the moving ring 402 drives the rotating bar 404 to swing, and the swing of the rotating bar 404 drives the beating rod 403 to swing, so that the beating rod 403 is in contact with the elastic protective net 102.

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

[0045] Collection boxes 406 are symmetrically installed in the bottom of the fixed base 401, and a collection port is provided at the top of the side where the two collection boxes 406 are away from each other, and a filter is provided at the top of the side where the two collection boxes 406 are close to each other. The ends of the two collection boxes 406 close to each other are fixedly installed with mounting blocks, and the two opposite mounting blocks are movably inserted into the inside of the fixed base 401, and two locking screws 407 are installed on the outer surface of the fixed base 401, and the locking screw 407 is threadedly connected to two mounting blocks threadedly connected to the inside of the fixed base 401 for installing the collection box 406. During use, when the locking screw 407 is screwed in, the locking screw 407 is threadedly connected to the two mounting blocks threadedly connected to the inside of the fixed base 401, and the installation of the collection box 406 is completed at this time.

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

[0047] A cross bar 408 is rotatably installed at the bottom of the fixed base 401, and fans 409 are fixedly installed at both ends of the cross bar 408. A second bevel gear 412 is fixedly installed on the outer surface of the cross bar 408, and a motor 410 is fixedly installed at the top of the fixed base 401. The bottom end of the output shaft of the motor 410 is fixedly installed with a first bevel gear 411, and the first bevel gear 411 and the second bevel gear 412 are meshed 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. When in use, the motor 410 is turned on to drive the first bevel gear 411 to rotate, and the second bevel gear 412 is rotated by the rotation of the first bevel gear 411, and the cross bar 408 is rotated by the rotation of the second bevel gear 412, and the fan 409 is rotated by the rotation of the cross bar 408. At this time, the suction force generated by the rotation of the fan 409 collects the cleaned dust.

[0048] By adopting the above technical solution, the fan 409 can 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 pushes the device 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 state. In addition, when the sand flows in the annular groove 305, friction and collision will occur between the sand particles and between the sand and the annular groove 305, consuming the energy of the swing of the base 301 and playing a damping role, so that the swing amplitude of the base 301 gradually decreases, stopping the swing more quickly and returning to the equilibrium position;

[0051] Then, during the shaking process, 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 part of the shaking energy and allows the base 301 to return to the equilibrium position faster. At the same time, the elastic force of the damping spring telescopic rod 304 can help the counterweight 303 return to the initial position faster, thereby driving the base 301 as a whole to return to an upright state faster. 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 converted into each other, making the movement of the counterweight 303 more regular and directional, thereby accelerating the recovery speed of the base 301;

[0052] Finally, when the elastic protective net 102 needs to be cleaned, the audio body 2 is first turned off, the motor 410 is turned on to drive the first bevel gear 411 to rotate, and the rotation of the first bevel gear 411 drives the second bevel gear 412 to rotate, and the rotation of the second bevel gear 412 drives the cross bar 408 to rotate, and the rotation of the cross bar 408 drives the fan 409 to rotate, and then the electric telescopic rod 405 is turned on to drive the moving ring 402 to move back and forth, and the movement of the moving ring 402 drives the rotating bar 404 to swing, and the swing of the rotating bar 404 drives the slapping rod 403 to swing, so that the slapping rod 403 and the elastic protective net 102 contact, and the elastic protective net 102 vibrates, thereby cleaning the elastic protective net 102, and at the same time, the suction generated by the rotation of the fan 409 collects the cleaned dust, and the dust is stored inside the collection box 406.

[0053] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
