DETAILED DESCRIPTION

[0031] Embodiment 1:

[0032] See also Figures 1 to 6 The embodiment of the present invention provides a strip noise reduction speaker, which is mainly used to realize the fast switching between wired connection and wireless connection on the basis of effective protection. The speaker includes a speaker body 1, and a groove 101 is provided on the rear side of the speaker body 1, and a plurality of audio interfaces 102 are arranged in the groove 101. A protective component 2 for closing the groove 101 is provided on the rear side of the speaker body 1, and the protective component 2 includes a lower filter plate 201 and an upper filter plate 202, and the lower filter plate 201 and the upper filter plate 202 are relatively limited by a limiting component 4.

[0033] In actual use, the connecting wire can be inserted into the groove 101 through the protective component 2 and connected with the audio interface 102. When the connecting wire is inserted, the positions of the lower filter plate 201 and the upper filter plate 202 remain unchanged, and it can still play an effective protective role.

[0034] In this embodiment, a noise reduction module (not shown) is provided inside the audio body 1, which can reduce noise. The noise reduction module, the audio interface 102 and the connecting line are all existing mature technologies and will not be described in detail here.

[0035] Reference Figures 3 to 6 In this embodiment, preferably, the protection component 2 further includes a placement hole 203 for the connection line to pass through, and a plurality of shielding blocks 3 for closing the placement hole 203 are arranged inside the placement hole 203. When the connection line passes through the placement hole 203, the plurality of shielding blocks 3 can automatically open to avoid the connection line; when the connection line is pushed out of the placement hole 203, the plurality of shielding blocks 3 can automatically close to restore the closure of the placement hole 203.

[0036] In this embodiment, the placement hole 203 is a circular hole and is disposed on the upper filter plate 202, and the number of the shielding blocks 3 is four; in actual applications, the number of the shielding blocks 3 can be increased or decreased according to demand.

[0037] In the above structure, the shielding block 3 can be a quarter-circular plate, in which case the circular plate is rigid and is rotatably connected to the hole wall of the placement hole 203 through a rotating shaft and a torsion spring, and the torsion spring makes the circular plate have a tendency to rotate to be flush with the surface of the upper filter plate 202. Figure 6 As shown, the circular plate can also be rotated to the rear side of the placement hole 203 , and at this time, the insertion of the connecting wire through the placement hole 203 will not interfere with the shielding block 3 .

[0038] In the above structure, the circular plate can also be designed to be elastic and made of existing rubber and other materials. At this time, the circular plate is fixedly connected to the hole wall of the placement hole 203. At this time, the insertion of the connecting line through the placement hole 203 will still not interfere with the blocking block 3, but the blocking block 3 cannot be fully rotated to the back side of the placement hole 203.

[0039] It should be noted that the lower filter plate 201 and the upper filter plate 202 are both L-shaped, with filter holes that can play a role in filtering and protection, and the two are in an upper and lower relative state. The lower filter plate 201 and the upper filter plate 202 are in a U-shaped state as a whole when viewed from the left and right directions. The height dimension of the top surface of the lower filter plate 201 based on the sound body 1 needs to be lower than the height dimension of the audio interface 102 based on the sound body. At this time, the placement of the placement hole 203 and the blocking block 3 based on the upper filter plate 202 can correspond to the audio interface 102, which can effectively reduce the bending of the connecting line after the audio interface 102 is plugged in.

[0040] It should also be noted that the lower filter plate 201 is fixedly connected to the groove 101, while the upper filter plate 202 is slidably connected to the groove 101, and is slidably connected up and down; when the upper filter plate 202 slides down based on the groove 101, it is simultaneously in a corresponding state with the lower filter plate 201. At the same time, the lower filter plate 201 is preferably fixedly connected by a snap-fit ​​type to facilitate the rapid removal of the lower filter plate 201 and the upper filter plate 202.

[0041] Reference Figure 4 and Figure 5 In this embodiment, preferably, the limiting assembly 4 includes a boss 401 fixedly connected to the upper filter plate 202 and a slide groove 402 opened inside the lower filter plate 201, the boss 401 is fixedly arranged inside the upper filter plate 202 and corresponds to the slide groove 402 up and down, and when the boss 401 descends with the upper filter plate 202, the front surface of the boss 401 can be in contact with the inner wall of the lower filter plate 201, and at this time it also corresponds to the slide groove 402.

[0042] Furthermore, a lower triangular bar 403 is installed inside the slide groove 402 in a sliding manner, and an upper triangular bar 404 is elastically connected to the front surface of the boss 401 via a first spring 405. Under the action of gravity, the lower triangular bar 403 is in a state of descending to the bottom of the groove based on the slide groove 402, and the upper triangular bar 404 can slide back and forth based on the boss 401 through the first spring 405, and has a tendency to slide out relatively; of course, the upper triangular bar 404 will not be separated from the boss 401.

[0043] In the above structure, both the lower triangular bar 403 and the upper triangular bar 404 have inclined surfaces, and the inclined surfaces of the lower triangular bar 403 and the upper triangular bar 404 are inclined in opposite directions, so that when the upper triangular bar 404 descends with the boss 401, if it encounters the lower triangular bar 403, it will automatically shrink into the boss 401 and squeeze the first spring 405.

[0044] There is also a certain distance between the lower triangular bar 403 and the top wall of the slide groove 402, which allows the lower triangular bar 403 to slide up along the slide groove 402, and allows the upper triangular bar 404 to be inserted therein to form a stop. At the same time, the length of the lower triangular bar 403 along the front-to-back direction is greater than or equal to the length of the slide groove 402 along the front-to-back direction. At this time, the upper triangular bar 404 is not affected by the lower triangular bar 403 descending and driving the lower triangular bar 403 to rise, and the upper triangular bar 404 will not be stuck in the slide groove 402 after being separated from the lower triangular bar 403.

[0045] Reference Figure 4 and Figure 5 In this embodiment, preferably, a distance is provided between the upper filter plate 202 and the lower filter plate 201, and the distance allows the upper filter plate 202 to continue to slide downward after being flush with the top surface of the acoustic body 1, and is larger than the distance between the top surface of the lower triangular bar 403 and the top wall of the slide groove 402. Of course, in normal use, the distance will be blocked by the boss 401, so that the boss 401 not only has the function of accommodating the upper triangular bar 404 and the first spring 405, but also has the function of blocking the distance and closing the groove 101.

[0046] When in use, the speaker body 1 is placed at the position to be placed to play a broadcasting role, and the top surface of the upper filter plate 202 is flush with the top surface of the speaker body 1, and the upper triangular bar 404 is engaged between the top surface of the lower triangular bar 403 and the top wall of the chute 402. When a wired connection is required, the upper filter plate 202 is pressed downward to drive the boss 401 and the upper triangular bar 404 to continue to descend. At this time, the upper triangular bar 404 contacts the lower triangular bar 403 and shrinks into the boss 401, and then the boss 401 can drive the upper triangular bar 404 to move below the upper triangular bar 404. Then, the upper filter plate 202 is lifted upward, driving the boss 401 and the upper triangular bar 404 to rise. At this time, the upper triangular bar 404 can push the lower triangular bar 403 to rise synchronously until the lower triangular bar 403 abuts against the top wall of the groove 402. Then, the lower triangular bar 403 can no longer rise, causing the upper triangular bar 404 to shrink into the boss 401 and continue to rise along the inner wall of the lower filter plate 201 until they are completely separated. At this time, the upper filter plate 202 and the lower filter plate 201 are also separated.

[0047] Next, the connecting wire is inserted into the placement hole 203, and the shielding block 3 is automatically opened to avoid it, and then the connecting wire is plugged into the audio interface 102. Finally, the upper filter plate 202 is slid downward based on the groove 101, so that the upper triangular bar 404 contacts the top surface of the lower filter plate 201 and shrinks into the boss 401. When it moves into the slide groove 402, the upper triangular bar 404 can automatically extend and engage between the top surface of the lower triangular bar 403 and the top wall of the slide groove 402 through the first spring 405; thereby, the upper filter plate 202 and the lower filter plate 201 are relatively fixed.

[0048] In summary, through the coordination of the upper filter plate 202, the lower filter plate 201, the boss 401 and the slide 402, the groove 101 and the audio interface 102 can be effectively protected to prevent dust and other debris from entering and affecting the use of the audio interface 102; and after switching to a wired connection, the state between the upper filter plate 202 and the lower filter plate 201 remains unchanged, and can still play an effective protective role. The overall structure is concise and easy to use. The way of sliding the upper filter plate 202 up and down is more conducive to user operation, which can ensure the overall cleanliness of wired and wireless use. The space occupied by the two usage methods remains unchanged and will not affect the overall layout. The upper filter plate 202 can be effectively limited to avoid affecting the plug-in quality of the connecting line; at the same time, the detachable assembly of the upper filter plate 202 and the lower filter plate 201 is also more convenient for overall cleaning in the later stage, and is more practical.

[0049] Embodiment 2:

[0050] See also Figures 1 to 8 On the basis of the first embodiment, in order not to affect the insertion of the connecting line when the upper filter plate 202 is moved, the positions of the placement hole 203 and the blocking block 3 are improved: at this time, the placement hole 203 and the blocking block 3 are set on the lower filter plate 201, and the height of the lower filter plate 201 along the up and down directions is increased, so that the top surface height dimension of the lower filter plate 201 based on the audio body 1 is higher than the height dimension of the audio interface 102 based on the audio body 1; of course, there is still a distance between the upper filter plate 202 and the lower filter plate 201, and the blocking block 3 here can also be designed elastically.

[0051] Furthermore, the lengths of the slide groove 402 , the upper triangular bar 404 and the lower triangular bar 403 along the left-right direction can be relatively reduced, thereby forming a left-right avoidance with the placement hole 203 and the shielding block 3 .

[0052] When in use, the upper filter plate 202, the lower filter plate 201 and the upper triangular bar 404 and other structures are used to effectively protect the groove 101 and the audio interface 102 and ensure the same protection effect for wired use and wireless use. The working process and effect of this part are the same as those in the first embodiment and are not repeated here. The difference is that when making a wired connection, the upper filter plate 202 is removed, inserted through the placement hole 203 on the lower filter plate 201 and plugged with the audio interface 102, and then the upper filter plate 202 is slid downward to complete the limit.

[0053] In the first embodiment, the connection line is plugged in through the placement hole 203 of the upper filter plate 202. When the upper filter plate 202 is reset to limit the position, the connection line in the placement hole 203 will be pulled, thereby affecting the connection quality between the connection line and the audio interface 102. In severe cases, the connection line and the audio interface 102 may fall off, which has certain limitations in use.

[0054] Compared with the first embodiment, the connection line is connected through the connection hole 203 of the lower filter plate 201 through the coordination of the structures such as the lower filter plate 201, the placement hole 203 and the shielding block 3, so that it will not interfere with the disassembly and assembly of the upper filter plate 202, thereby ensuring the overall use effect after the connection line is plugged in. The overall solution is combined with the placement of the lower filter plate 201, which can also ensure the same protection effect for wired use and wireless use, and the plugging effect of the connection line will not be affected when the upper filter plate 202 is removed later, which is also more conducive to later cleaning (dust is mainly concentrated on the upper filter plate 202), and has stronger applicability.

[0055] Embodiment three:

[0056] See also Figures 1 to 10 On the basis of the second embodiment, in order to improve the overall application range, the connection between the placement hole 203 and the shielding block 3 is improved: the cross section of the placement hole 203 is T-shaped, and a plurality of sliding components 5 are slidably installed in the placement hole 203. The number of sliding components 5 is equal to that of the shielding block 3 and is used to rotatably place the shielding block 3, that is, the shielding block 3 is rotatably connected to the sliding components 5. In this embodiment, there are four sliding components 5 and four shielding blocks 3.

[0057] When the connecting wire is inserted from the mounting hole 203, on the one hand, the four blocking blocks 3 can be automatically opened, and the four sliding components 5 can also be moved away from each other. At the same time, when the four sliding components 5 move away from each other, they can automatically fill the gap generated after moving away from each other, so that only the middle through hole is left for the connecting wire to pass through.

[0058] Reference Fig. 9 and Fig.10In this embodiment, preferably: the sliding assembly 5 includes a base 501 that is slidably matched with the placement hole 203 and is used to rotatably install the shielding block 3. The assembly of the shielding block 3 and the base 501 is also through a rotating shaft and a torsion spring; the end of the base 501 is elastically connected to the hole wall of the placement hole 203 through a second spring 502, and the second spring 502 makes the base 501 have a tendency to approach the center of the placement hole 203. The surface of the base 501 close to the sound body 1 is slidably installed with two fan-shaped plates 503 through an arc groove 505. The two fan-shaped plates 503 are elastically connected by a third spring 504, and the third spring 504 makes the two fan-shaped plates 503 have a tendency to move away from each other.

[0059] In the above structure, the base 501 can only reciprocate in a single direction based on the placement hole 203, and the fan-shaped plate 503 can slide based on the sliding of the arc groove 505 and the placement of the third spring 504, so that the corresponding fan-shaped plates 503 on two adjacent bases 501 can fit each other. In order to ensure the fitting state of the fan-shaped plates 503, the arc groove 505 can be set as a part of the annular groove.

[0060] It can be understood that the surface of the fan-shaped plate 503 away from the second spring 502 and the surface of the base 501 away from the second spring 502 are designed to have the same arc, and the four bases 501 are combined with the eight fan-shaped plates 503 to form a circle with a space in the middle. This circle is closed when the blocking block 3 is closed and is used for the insertion of the connecting line.

[0061] When in use, the upper filter plate 202, the lower filter plate 201 and the upper triangular bar 404 and other structures are used to effectively protect the groove 101 and the audio interface 102 and ensure the same protection effect for wired use and wireless use. The lower filter plate 201, the placement hole 203 and the shielding block 3 and other structures allow the connection line to be connected through the placement hole 203 of the lower filter plate 201 and to be separated from the upper filter plate 202. The working process and effect of this part are the same as those in the second embodiment and will not be repeated here. The difference is that when the connection line is inserted, the four shielding blocks 3 can be automatically pushed open. When the diameter of the connection line is large, the four bases 501 can also move away from each other and squeeze the second spring 502. When the base 501 moves, the two fan-shaped plates 503 on the base 501 can also move away from each other under the action of the third spring 504, so that the two adjacent fan-shaped plates 503 can maintain a fitted state.

[0062] In the second embodiment, the diameter of the connecting wire needs to be smaller than the diameter of the mounting hole 203. However, most existing connecting wires are provided with plugs, and the sizes of the plugs and the connecting wires are different, so that the mounting hole 203 cannot be well adapted to different connecting wires and plugs, which affects the connection between the connecting wire and the audio interface 102 through the mounting hole 203, and there are certain limitations in use.

[0063] Compared with the second embodiment, through the cooperation of the structures such as the shielding block 3, the placement hole 203, the base 501 and the fan-shaped plate 503, the base 501 can slide relatively based on the placement hole 203 and drive the shielding block 3 to move synchronously, and the adjacent fan-shaped plates 503 can maintain a fitting state when moving, so that it can be used for connecting wires and plugs of different diameters, effectively improving the overall scope of application. The overall solution is combined with the placement of the shielding block 3, and the second spring 502 can also enhance the limiting effect of the connecting wire, avoid the separation of the connecting wire from the audio interface 102, and reduce the gap between the connecting wire and the base 501 and the shielding block 3; at the same time, the movable design of the base 501 allows the connecting wire to be slightly bent and avoided when plugged in, avoiding the excessive bending angle of the connecting wire affecting the service life, and meeting more needs in actual use.
