Technical Field

[0001] The present invention relates to the field of speakers, and particularly to a speaker with waterproof and dustproof functions. Background Art

[0002] The speaker, commonly known as the "loudspeaker", is a very commonly used electro-acoustic transducer. Its performance has a great impact on the sound quality. The speaker is mainly composed of components such as a paper cone, a chassis, a voice coil, a permanent magnet, and an elastic sheet. Among them, components such as the voice coil, the permanent magnet, and the elastic sheet are all located at the rear end of the paper cone. Each component cooperates to drive the paper cone to vibrate and produce sound. Patent: CN221263976U discloses a speaker with a dustproof structure, including a speaker body. A shell cover is installed on one side of the outer surface of the speaker body, a protective net is installed on the other side of the speaker body, a horn mouth is opened on the inner surface of the speaker body, an annular groove is opened on one side of the outer surface of the speaker body, a clamping groove is opened on the inner surface of the annular groove, a fixing block is installed at one end of the outer surface of the horn mouth, and a spring is fixedly installed between the two fixing blocks. This device realizes the function of moving the position of the speaker by setting a handle on the speaker, and can block dust from floating into the interior of the speaker through the protective net. At the same time, it can provide convenience for cleaning the protective net through the clamping block, prevent the blockage of the protective net, improve the service life of the speaker, and facilitate the use of the speaker. Dust prevention through the protective net in the above technology cannot achieve a waterproof effect, and the disassembly method of the protective net is complex, and the device itself does not have a shock absorption and buffering effect, so it needs to be improved. For this reason, we propose a speaker with waterproof and dustproof functions. Summary of the Invention

The outer side wall of the rack is meshed with the outer side wall of the toothed ring.

[0005] Furthermore, the front surface of the cover plate is located between the dust-proof mechanism and the waterproof mechanism, and two through-type sound outlets are provided inside the cover plate and located inside the two toothed rings. Two through-type arc-shaped grooves are provided on the front surface of the cover plate and located outside the sound outlets.

[0006] Furthermore, an extrusion column is fixedly connected to the front surface of the toothed ring and located inside the arc-shaped groove. The extrusion column is slidably connected to the arc-shaped groove.

[0007] Furthermore, the dust-proof mechanism includes a mounting sleeve. The mounting sleeve is located outside the sound outlet. The rear surface of the mounting sleeve is fixedly connected to the front surface of the housing. A dust-proof net is snap-fitted inside the mounting sleeve.

[0008] Furthermore, two snap-fitting openings are provided on the outer side wall of the dust-proof net. Two wedge-shaped plugging blocks are slidably connected to the outer side wall of the mounting sleeve. Springs are fixedly connected between the wedge-shaped plugging blocks and the mounting sleeve. The wedge-shaped plugging blocks are adapted to the extrusion columns.

[0009] Furthermore, the sound mechanism includes a mounting seat. Two air cavities are provided inside the mounting seat. A first air pipe is fixedly connected and communicated between the air cavity and the first air box. A second piston plate is slidably connected inside the air cavity. Two connecting rods are fixedly connected to the front surface of the second piston plate. The front ends of the plurality of connecting rods all penetrate to the front of the mounting seat and are commonly fixedly connected to a mounting plate. The mounting plate is slidably connected to the first air pipe. Two loudspeaker bodies are embedded and mounted inside the mounting plate. An electric push rod is fixedly connected between the mounting plate and the mounting seat. A sealing ring is fixedly connected to the front surface of the mounting seat and located outside the connecting rod.

[0010] Furthermore, the shock-absorbing and buffering mechanism includes a bottom plate, which is located on the inner side of the base and is slidably connected to the base. The lower surface of the bottom plate is fixedly connected to a lifting seat, and the upper surface of the bottom plate is fixedly connected to the lower surface of the shell.

[0011] Furthermore, an air box 2 is provided on the lower surface of the lifting seat, and a piston plate 3 is slidably connected to the inside of the air box 2. The opposite sides of the two piston plates 3 are located on the outside of the air box 2 and are fixedly connected to a traction rod. The end of the traction rod away from the piston plate 3 is fixedly connected to a U-shaped connecting rod, and the lower surface of the U-shaped connecting rod is rotatably connected to a movable rod through a rotating shaft, and the end of the movable rod away from the U-shaped connecting rod is rotatably connected to a rotating part 4 through a rotating shaft.

[0012] Furthermore, a second ventilation pipe is fixedly connected between the second air box and the two air cavities.

[0013] Beneficial effect: When playing sound, the electric push rod extends, the speaker body moves forward, the gas inside the air cavity is passed into the inside of the air box, the control rack extends, the gear ring is turned to rotate, and the multiple sealing plates are controlled to open, so that the speaker body can sound through the speaker port. When the speaker body is closed, the electric push rod retracts, the control rack retracts, and the gear ring is turned to reset, so that the multiple sealing plates are closed, thereby achieving a waterproof effect on the speaker body inside the shell; When multiple sealing plates are combined and closed, the extrusion column moves away from the wedge-shaped plug-in block. At this time, the wedge-shaped plug-in block is affected by the spring pull, and only part of the tapered end is inserted into the inside of the snap-fit opening. At this time, the dust screen can be rotated to make the tip of the wedge-shaped plug-in block disengage from the snap-fit opening, and then the dust screen can be removed from the inside of the mounting sleeve to facilitate disassembly and cleaning. When the multiple sealing plates are separated and opened, the extrusion column will squeeze the wedge-shaped plug-in block into the inside of the snap-fit opening to position the dust screen and prevent it from falling off. The device is supported on the bottom of the shell through the shock-absorbing telescopic seat, which has a shock-absorbing and buffering effect on the device body. The speaker body moves forward to make sound under the control of the electric push rod, or moves backward to close. At the same time, the air cavity inflates or exhausts air into the inside of air box one, and also exhausts or inflates air into the inside of air box two, so that the two traction rods drive the two U-shaped connecting rods to move relative to or away from each other, so that the buffer seat is pulled to rotate under the pulling of the movable rod, so that the two shock-absorbing telescopic seats set on the upper surface of the buffer seat can be controlled to alternately support when the speaker is in different positions, thereby extending the service life of the shock-absorbing telescopic seat and making it more applicable.

[0016] To make the technical solution of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments.

[0017] Embodiment 1 As Figure 1 and Figure 5As shown, a speaker with waterproof and dustproof functions is provided, comprising a housing 1, a cover plate 2 is detachably mounted on the front surface of the housing 1, and two waterproof mechanisms 3 are symmetrically arranged on the rear surface of the cover plate 2; The waterproof mechanism 3 includes multiple sealing plates 301. The outer wall of the sealing plate 301 is integrally formed with a rotating member 1 302 and a rotating member 2 303. The rotating member 1 302 is rotatably connected to the rear surface of the cover plate 2 via a rotating shaft. The outer wall of the rotating member 2 303 is rotatably connected to an arc-shaped pull rod 304 via a rotating shaft. A gear ring 305 is commonly provided on the outer sides of the multiple sealing plates 301. The gear ring 305 is rotatably connected to the opposite side of the cover plate 2 via a rotating shaft. The end of the arc-shaped pull rod 304 away from the rotating member 2 303 is rotatably connected to the rotating member 3 306 via a rotating shaft. The outer wall of the rotating member 306 is fixedly connected to the inner side of the gear ring 305. When the waterproof mechanism 3 is in use, the gear ring 305 can be turned to rotate, and the multiple sealing plates 301 can be driven to rotate along the rotating member 1 302 under the pull of the arc-shaped pull rod 304, and then the multiple sealing plates 301 can be controlled to merge and close or separate and open.

[0018] like Figure 1 、 Figure 4 、 Figure 6 、 Figure 7 As shown, two dust-proof mechanisms 4 are symmetrically provided on the front surface of the cover plate 2; The dustproof mechanism 4 includes a mounting sleeve 401 , which is located outside the speaker port 9 . The rear surface of the mounting sleeve 401 is fixedly connected to the front surface of the housing 1 , and a dustproof net 402 is engaged with the inner side of the mounting sleeve 401 .

[0019] The outer wall of the dust screen 402 is provided with two engaging openings 403. The outer wall of the mounting sleeve 401 is slidably connected to two wedge-shaped plug-in blocks 404. A spring 405 is fixedly connected between the wedge-shaped plug-in blocks 404 and the mounting sleeve 401. The wedge-shaped plug-in blocks 404 are adapted to the extrusion column 11. The front surface of the cover plate 2 is located between the dustproof mechanism 4 and the waterproof mechanism 3, and has two through-type speaker openings 9 on the inner side of the two gear rings 305. The front surface of the cover plate 2 has two through-type arc-shaped grooves 10 on the outer side of the speaker openings 9. The front surface of the gear ring 305 is located inside the arc groove 10 and is fixedly connected to an extrusion column 11, which is slidably connected to the arc groove 10; When the multiple sealing plates 301 of the waterproof mechanism 3 are combined and closed, the extrusion column 11 is away from the wedge-shaped plug-in block 404. At this time, the wedge-shaped plug-in block 404 is pulled by the spring 405, and only part of the tapered end is inserted into the inside of the engaging opening 403. At this time, the dust screen 402 can be rotated to make the tip of the wedge-shaped plug-in block 404 disengage from the engaging opening 403, and then the dust screen 402 can be removed from the inside of the mounting sleeve 401, so as to achieve the effect of easy disassembly and cleaning; When the multiple sealing plates 301 are separated and opened, the squeezing column 11 squeezes the wedge-shaped plug-in block 404 to be inserted into the engaging opening 403 to position the dustproof net 402 and prevent the dustproof net 402 from being separated.

[0020] like Figure 5 As shown, the rear surface of the housing 1 is provided with linkage mechanisms 5 on the outside of the two waterproof mechanisms 3; The linkage mechanism 5 includes an air box 501, which is fixedly connected to the opposite side of the cover plate 2.

The outer wall of the rack 503 is meshed with the outer wall of the gear ring 305. By inflating or deflating the air box 501, the piston plate 502 is controlled to slide along the inside of the air box 501, so that the rack 503 drives the gear ring 305 to rotate, thereby controlling the opening or closing of multiple sealing plates 301.

[0021] like Figure 3 As shown, a speaker mechanism 6 is provided inside the housing 1; The speaker mechanism 6 includes a mounting base 601, which has two air cavities 602 defined therein.

An electric push rod 608 is fixedly connected between the mounting plate 606 and the mounting base 601. A sealing ring 609 is fixedly connected to the front surface of the mounting base 601, located outside the connecting rod 605. When the device needs to play sound, the electric push rod 608 is controlled to extend, pushing the mounting plate 606 and the speaker body 607 forward. At this time, the internal gas of the air cavity 602 will pass into the air box 501 through the ventilation tube 603, the rack 503 is controlled to extend, and the gear ring 305 is turned to rotate, and then the multiple sealing plates 301 are controlled to open, so that the speaker body 607 can make a sound through the speaker port 9. After the speaker body 607 is closed, the electric push rod 608 is controlled to retract. At this time, the air cavity 602 will draw out the internal gas of the air box 501, the rack 503 is controlled to retract, and the gear ring 305 is turned to reset, so that the multiple sealing plates 301 are closed, thereby having a waterproof effect on the speaker body 607 inside the shell 1.

[0022] like Figure 1 、 Figure 2 、 Figure 8 and Figure 9 As shown, a base 7 is provided on the lower surface of the housing 1, and a shock absorbing and buffering mechanism 8 is provided between the base 7 and the housing 1; The shock absorbing and buffering mechanism 8 includes a bottom plate 801, which is located inside the base 7 and is slidably connected to the base 7. The lower surface of the bottom plate 801 is fixedly connected to the lifting seat 802, and the upper surface of the bottom plate 801 is fixedly connected to the lower surface of the shell 1; An air box 2 803 is provided on the lower surface of the lifting seat 802, and a piston plate 3 804 is slidably connected to the inside of the air box 2 803. The opposite sides of the two piston plates 3 804 are located on the outside of the air box 2 803 and are fixedly connected with a traction rod 805. The end of the traction rod 805 away from the piston plate 3 804 is fixedly connected to a U-shaped connecting rod 806. The lower surface of the U-shaped connecting rod 806 is rotatably connected to a movable rod 807 through a rotating shaft. The end of the movable rod 807 away from the U-shaped connecting rod 806 is rotatably connected to a rotating member 4 812 through a rotating shaft. The outer wall of the rotating member 4 812 is fixedly connected to a buffer seat 808. The center of the lower surface of the buffer seat 808 is rotatably connected to the inner lower surface of the base 7 through a rotating shaft. The upper surface of the buffer seat 808 is fixedly connected to two shock-absorbing telescopic seats 809, and the top of the shock-absorbing telescopic seat 809 is integrally formed with a sphere 810. The second air box 803 and the two air cavities 602 are fixedly connected to each other via a second ventilation pipe 811; The device is supported at the bottom of the housing 1 by the provided shock-absorbing telescopic seat 809, which has a shock-absorbing and buffering effect on the device body. Moreover, under the control of the electric push rod 608, the speaker body 607 moves forward to emit sound, or moves backward to close. When the air cavity 602 inflates or deflates into the first air tank 501, it also pumps air out of or inflates the second air tank 803 at the same time, causing the two traction rods 805 to drive the two U-shaped connecting rods 806 to move relative to or away from each other. Thus, under the pull of the movable rod 807, the buffer seat 808 is pulled to rotate, so that the two provided on the upper surface of the buffer seat 808 can alternately support the shock-absorbing telescopic seat 809 when the speaker is in different positions, extending the service life of the shock-absorbing telescopic seat 809 and having stronger applicability.

[0023] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the invention patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
