Description
Technical Field
[0001] The utility model relates to the field of audio, in particular to a dustproof audio for a conference room. Background Art
[0002] Conference room speakers can provide high-quality sound transmission effects, ensuring that participants can clearly and accurately hear the speaker's speech and presentation content. This helps participants better understand and receive meeting information, thereby improving the efficiency and quality of the meeting. Conference room speakers are often installed on high walls through brackets, which helps to evenly distribute the sound in the conference room. The speakers installed at high places can better cover the entire conference room, avoid the formation of "dead spots" near the ground, and ensure that every participant can hear the sound clearly. At the same time, it can reduce obstacles such as tables and chairs that hinder the propagation of sound. However, after long-term use of the speakers, dust floating in the air is likely to accumulate in large quantities in the mesh of the protective net installed on the outside of the speaker. At the same time, because the speakers are installed at a high place, it will make it difficult to clean the dust in the mesh of the protective net, and then the dust accumulated in the mesh of the protective net will block the propagation of the sound emitted by the speakers, thereby reducing the use effect of the speakers and reducing the clarity and distance of sound propagation. Therefore, a dust-proof speaker for conference rooms is needed to solve the above problems. Utility Model Content

Two electric telescopic rods 3 are symmetrically fixedly installed on the left and right ends of the audio body 1, and the two electric telescopic rods 3 are electrically connected to the external power supply through a control switch. The electric telescopic rod 3 is fixedly connected to the audio body 1 through a No. 1 connecting piece 7, and a No. 2 connecting piece 8 is fixedly installed on the front end of the telescopic rod of the electric telescopic rod 3. Two dustproof shielding structures 4 are movably installed on the two U-shaped guide rails 2, and the dustproof shielding structure 4 is fixedly connected to the telescopic rod of the electric telescopic rod 3 at the same time. The dustproof shielding structure 4 consists of a dustproof shielding plate 9, an installation limit column 10 and a connecting rubber sheet 11. The dustproof shielding plate 9, the installation limit column 10 and the connecting rubber sheet 11 are all provided with a plurality of them, and the installation limit column 10 is fixed Installed at the upper and lower ends of the dustproof shielding plate 9, the connecting rubber sheet 11 connects the two adjacent dustproof shielding plates 9 together, the dustproof shielding plate 9 and the connecting rubber sheet 11 on the dustproof shielding structure 4 are both located between the two U-shaped guide rails 2, the installation limit column 10 is slidably installed in the U-shaped guide rail 2, and one of the dustproof shielding plates 9 on the dustproof shielding structure 4 is fixedly connected to the second connecting piece 8. By arranging the U-shaped guide rail 2 and the electric telescopic rod 3 on the audio body 1, and arranging the dustproof shielding structure 4 on the U-shaped guide rail 2 and the electric telescopic rod 3, the dustproof shielding structure 4 can be used to shield and protect the protective net 6 when the audio body 1 is not in use, thereby preventing dust from accumulating in the mesh of the protective net 6 when the audio body 1 is not in use, thereby reducing the influence of dust on the audio body 1, so that the audio body 1 still has a good use effect after long-term use.
