[0002] A speaker is a device that converts audio signals into sound. It has a built-in power amplifier that can amplify the audio signal and then emit sound. The speaker is the terminal of the entire audio system and is an important component of the audio system.

[0003] Traditional desktop speakers are provided with sound holes in their speaker part to facilitate the normal operation of the speaker, and a dustproof net is provided inside the sound hole to prevent dust from entering the speaker. However, since the sound hole is exposed to the outside, dust will adhere to the sound hole during actual use. At this time, the contact between the dust and the water vapor in the air will cause the sound hole to be blocked, affecting the sound effect of the speaker. There are certain deficiencies in its use. For this reason, we propose a waterproof and dustproof structure for the speaker. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-4A waterproof and dustproof structure of a speaker comprises a base 1, a non-slip pad 2 is installed on the top of the base 1, a support column 3 is fixed on the top of the base 1, a mounting plate 4 is fixed on the support column 3, a protective cover mechanism 5 is slidably sleeved on the support column 3, the protective cover mechanism 5 comprises a spline sleeve 51 sleeved on the support column 3, a movable plate 52 is fixed on the spline sleeve 51, a supporting spring 53 is installed between the movable plate 52 and the base 1, a protective cover 54 is rotatably connected to the movable plate 52, a fixing block 55 is fixed on the inner wall of the protective cover 54, the supporting spring 53 is sleeved on the support column 3, a spline groove is opened on the surface of the support column 3, the support column 3 and the spline sleeve 51 are slidably connected, the number of the fixing blocks 55 is several groups, the several groups of fixing blocks 55 are located on the inner wall of the protective cover 54 and are symmetrically distributed, the fixing blocks 55 are slidably connected to the mounting plate 4 through a slide groove, and a speaker mechanism 6 is fixed on the mounting plate 4 The speaker mechanism 6 includes a shell 61 fixed on the top of the mounting plate 4. The shell 61 is a hollow cylindrical structure. A speaker body 62 is installed inside the shell 61. A partition net 63 is installed on the side of the shell 61. A threaded sleeve 64 is installed inside the shell 61. The inside of the threaded sleeve 64 is connected with a connecting column 66 through a thread. A cover plate 65 is installed on the top of the connecting column 66. The connecting column 66 is inserted into the inside of the shell 61 and is connected with an activated carbon filter element 67. The speaker mechanism 6 is located inside the protective cover mechanism 5. By setting the protective cover mechanism, the speaker mechanism installed on the mounting plate is exposed by moving the protective cover mechanism, which is convenient for protecting the speaker mechanism when idle and preventing dust from adhering to the partition net. At the same time, an activated carbon filter element is arranged inside the speaker mechanism, which can effectively prevent water vapor in the air from polluting the speaker body and improve the service life of the speaker body. The device has a simple structure and is very convenient to use.

[0020] When the device is in use, it is placed on the desktop through the base 1. The setting of the anti-skid pad 2 can effectively prevent the device from sliding on the surface. When in use, first pull the protective cover 54 downward, the protective cover 54 drives the fixed block 55 to slide in the slide groove on the side of the mounting plate 4, and the protective cover 54 drives the movable plate 52 to make the movable plate 52 close to the base. At this time, the supporting spring 53 is compressed. When the fixed block 5 is separated from the side of the mounting plate 4, the protective cover 54 is rotated and the pressure on the protective cover 54 is removed. At this time, under the action of the elastic force of the supporting spring 53, the movable plate 52 drives the fixed block 55 through the protective cover 54, and the fixed block 55 is against the bottom of the mounting plate 4. At this time, the sound The box mechanism 6 is completely exposed, and audio output is performed through the speaker body 62 inside the speaker mechanism 6. When the speaker body 62 is in use, the internal activated carbon filter element 67 absorbs water vapor in the air to prevent water vapor from contaminating the circuit of the speaker body 62. When used for a long time, the connecting column 66 and the activated carbon filter element 67 can be removed by rotating the cover plate 65, which facilitates the replacement of the activated carbon filter element 67. After use, the protective cover 54 is rotated, and the protective cover 54 drives the fixing block 55 to slide into the sliding groove on the side of the mounting plate 4. At this time, under the action of the elastic force of the supporting spring 53, the protective cover 54 moves upward until it connects with the cover plate 65.

[0021] To sum up, compared with the prior art, the utility model provides a protective cover mechanism, and the speaker mechanism installed on the mounting plate is exposed by moving the protective cover mechanism, so as to protect the speaker mechanism when idle and prevent dust from adhering to the partition net. At the same time, an activated carbon filter is provided inside the speaker mechanism, which can effectively prevent water vapor in the air from polluting the speaker body and increase the service life of the speaker body. The device has a simple structure and is very convenient to use.
