Audio equipment with noise reduction function

Abstract

The invention discloses audio equipment with a noise reduction function, and relates to the field of audio equipment. The audio equipment with the noise reduction function comprises a box body and a protection ring, a loudspeaker and two fixing cylinders are embedded in the front face of the box body, an annular clamping groove is formed in the front face of the box body, the fixing cylinders are symmetrically arranged on the two sides of the annular clamping groove, insertion grooves are formed in the front faces of the fixing cylinders, and a positioning groove and a limiting groove are formed in the outer surface of the fixing barrel, a sliding plate is slidably connected to the inner wall of the inserting groove, and a first telescopic shaft and a limiting spring are fixedly connected between the sliding plate and the inner bottom wall of the fixing barrel. According to the audio equipment with the noise reduction function, a limiting spring rebounds to push a limiting block to move towards a positioning groove, at the moment, a protection ring can be pulled outwards, the limiting block is separated from a limiting groove, an insertion block is separated from an insertion groove, a rubber ring is separated from an annular clamping groove, and a protection net cover and a loudspeaker can be cleaned.

Description

technical field [0001] The invention relates to the technical field of audio equipment, in particular to an audio equipment with a noise reduction function. Background technique [0002] Audio equipment is mainly a general term for audio input and output equipment. It includes many types of products, which can generally be divided into power amplifiers, speakers, multimedia consoles, digital mixers, audio sampling cards, synthesizers, mid-high frequency speakers, and microphones. , sound card, headphones, etc. in the PC. [0003] The most used audio equipment in daily life is the speaker. The outer surface of the speaker is generally equipped with a dust cover during production, so as to effectively prevent the speaker from dust. However, in some areas with large wind and sand, even if there is Dust cover, there will still be fine dust passing through the dust cover and accumulating on the speaker.

[0003] The most used audio equipment in daily life is the speaker. The outer surface of the speaker is generally equipped with a dust cover during production, so as to effectively prevent the speaker from dust. However, in some areas with large wind and sand, even if there is Dust cover, there will still be fine dust passing through the dust cover and accumulating on the speaker. The dust entering the speaker may cause noise in the speaker. At the same time, it is easy to get stuck in the gap of the dust cover. Too much dust may cause sound transmission, so it is often necessary to disassemble the dust cover and clean it, but the existing dust cover is usually fixed on the front of the speaker, it is difficult for non-professionals to disassemble it for cleaning. installation, so we propose an audio device with noise canceling
