Description

Technical Field

[0001] The utility model relates to the technical field of audio, in particular to a sound machine with a coil dustproof structure. Background Art

[0002] Audio refers specifically to an audio system that is a combination of electrical equipment that produces sound. During a meeting, in order to enable participants to fully listen to the speech, conference audio is often used to control the volume and transmit the speech. The coil, also known as the voice coil, is directly defined as a coil through which current passes through the speaker. It is an important part of the mechanical wave system of an electric speaker, and can also be said to be the heart of the speaker. The performance of the voice coil will affect the speaker's sound intensity characteristics, sound intensity level, impedance curve, distortion, transient characteristics, speaker parameters, sound quality, etc., especially the speaker's power handling and lifespan. Just like the fatal factors of heart disease, speaker damage often starts from the voice coil.

[0003] After searching: Chinese patent number CN213436249U is a dustproof device for conference audio equipment, including a protective box, a dual-axis motor is fixedly installed inside the protective box, and the output shafts at both ends of the dual-axis motor are fixedly installed with rotating shafts, and the end of the rotating shaft away from the dual-axis motor is threadedly installed with a rotating screw, and the side wall of the rotating screw is threadedly installed with a threaded rotating rod, and the side of the threaded rotating rod away from the dual-axis motor is provided with a fixed rod. And Chinese patent number CN218550086U is a dustproof device for conference audio equipment with a protective box, including a protective box and a speaker arranged inside the protective box, the front end of the inner cavity of the protective box is provided with a symmetrical slide groove, the right end inner wall of the slide groove is provided with a positioning hole, a dustproof plate is slidably connected in the slide groove, and a clamping mechanism is provided at the upper and lower ends of the right side of the dustproof plate.

[0004] However, the above-mentioned audio dust-proof technology only protects the surface of the audio, but does not protect the internal audio coil from dust. A small amount of dust will still adhere to the coil, causing corrosion damage to the surface of the coil, reducing the service life of the voice coil, and the dust-proof net on the speaker is not easy to disassemble, which is not conducive to regular cleaning and replacement, affecting the normal use of the audio. Therefore, we propose a speaker with a coil dust-proof structure to solve the above problems. Utility Model Content
