[0015] In summary, the utility model mainly has the following beneficial effects:

[0016] 1. The utility model sets a protective plate. When the pickup is not in use, the electric guide rail is started, and the electric guide rail drives the slider on its outer wall to move. After the slider moves, it drives the protective plate to move. Therefore, the two sets of protective plates move toward each other to achieve the closure of the two sets of protective plates. At this time, the sound hole will be wrapped by the protective plate on its inner side, so as to effectively prevent dust and other impurities from affecting the sound hole. Similarly, when in use, the electric guide rail is started to run in the reverse direction. At this time, the slider drives the two sets of protective plates to move back to each other, so that the sound hole is exposed and the pickup can be used normally.

[0017] 2. The utility model sets a filter, and when the two groups of protective plates are unfolded, the filter located in the two groups of protective plates will be unfolded under the action of the two groups of protective plates moving away from each other. Specifically, the driving roller will pull the filter when following the movement of the protective plate, so that the filter in the other group of protective plates drives the driven roller to rotate, thereby meeting the unfolding requirement of the filter. Therefore, after the protective plate is unfolded, a filter defense line will be unfolded on the outside of the sound hole, thereby providing protection for the sound hole of the pickup during operation.

[0027] A box-type pickup that protects the sound hole, such as Figure 1-Figure 2 As shown, the pickup body 1 comprises a sound pickup body, a sound hole 2 for sound pickup is opened at the end of the sound pickup body 1, and protective plates 3 for protecting the sound hole 2 are arranged on both sides of the sound hole 2.

[0028] Furthermore, in this embodiment, the top and bottom ends of the protective plate 3 are both provided with a slide groove 4 opened on the end surface of the pickup body 1, and an electric guide rail 5 is installed inside the slide groove 4, and a slider 6 adapted to the electric guide rail 5 is sleeved on the outer wall of the electric guide rail 5;

[0029] In addition, the end of the slider 6 extends to the top of the protective plate 3 and is fixedly connected to the top of the protective plate 3, so that the movement of the slider 6 drives the protective plate 3 to move.

[0030] Embodiment 2

[0031] like Figure 3-Figure 5 As shown, it is the second embodiment of this scheme. In the first embodiment, the protective plate 3 is used to protect the sound hole of the pickup when it is not in use, while in this embodiment, a filter screen 7 is added to protect the sound hole of the pickup when it is in use.

[0032] Specifically, a filter screen 7 is provided on the outer side of the sound hole 2 between the two sets of protection plates 3 to further protect the sound hole 2;

[0033] Furthermore, the side walls of the two sets of protection plates 3 are provided with through holes 8 for the auxiliary filter screen 7 to be unfolded, and both sides of the filter screen 7 extend to the inside of the two sets of protection plates 3, and the inside of the two sets of protection plates 3 are provided with cavities 9 to accommodate the filter screen 7;

[0034] In addition, in the present embodiment, a driving roller 10 is installed inside a group of protective plates 3 located in the cavity 9, and one end of the filter screen 7 is wrapped and connected to the outer wall of the driving roller 10; another group of protective plates 3 is located inside the cavity 9 and is rotatably connected to a driven roller 11 through a bearing, and the filter screen 7 is sleeved on the outer wall of the driven roller 11 to achieve the deployment of the auxiliary filter screen 7.

[0035] See also Figure 5 The bottom end of the driving roller 10 is located in the protective plate 3, and a driving motor 12 is installed with an output end portion and synchronously connected to the driving roller 10. The driving motor 12 is electrically connected to the counter inside the pickup body 1 through the single-chip microcomputer to realize the driving effect on the driving roller 10, thereby completing the replacement of the filter 7.

[0036] The working principle of the utility model is as follows: when the pickup is not in use, the electric guide rail 5 is started, and the electric guide rail 5 drives the slider 6 on its outer wall to move, and the slider 6 moves to drive the protective plate 3 to move, so that the two sets of protective plates 3 move toward each other to achieve the closure of the two sets of protective plates 3, and at this time, the sound hole 2 is wrapped inside by the protective plate 3, so as to effectively prevent dust and other impurities from affecting the sound hole;

[0037] Similarly, when in use, the electric guide rail 5 is started to run in the reverse direction, and the slider 6 will drive the two sets of protective plates 3 to move in opposite directions, so that the sound hole 2 is exposed and the pickup can be used normally;

[0038] Furthermore, when the two groups of protection plates 3 are unfolded, the filter screens 7 in the two groups of protection plates 3 will be unfolded under the action of the two groups of protection plates 3 moving in opposite directions. Specifically, the driving roller 10 will pull the filter screen 7 when following the movement of the protection plates 3, so that the filter screen 7 in the other group of protection plates 3 will drive the driven roller 11 to rotate, thereby meeting the unfolding requirement of the filter screen 7. Therefore, after the protection plates 3 are unfolded, a line of filter screen 7 defense will be unfolded on the outside of the sound hole 2, so that the sound hole can also be protected for the pickup during operation.

[0039] In addition, it is worth noting that a driving system is added in the present embodiment to realize regular replacement of the filter 7. Specifically, when the number of pickup starts reaches the set value of the counter, the counter will control the operation of the drive motor 12 through the single-chip microcomputer. After the drive motor 12 is running, it will drive the drive roller 10 to rotate, thereby causing more filter 7 to be wrapped around the drive roller 10, thereby realizing the replacement of the filter 7 and further improving the protective effect of the filter 7.
