Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Specifically, referring to fig. 1 to 8, the present invention provides a technical solution: a dustproof acoustic gauze comprises a first fixing ring 1, a second fixing ring 2, an electrostatic dust removal component and a magnet adsorption component.

Wherein, fixedly connected with gauze body 4 on the first solid fixed ring 1, gauze body 4 is used for covering the position of the sound outlet of stereo set.

In order to install the electrostatic dust removal component, the second fixing ring 2 is fixedly and detachably arranged on the first fixing ring 1, the second fixing ring 2 is provided with a mounting groove 5, and the electrostatic dust removal component is arranged in the mounting groove 5.

In order to let electrostatic storage part later stage direction dismouting arrangement, this application has set up the magnetic adsorption part, and wherein, the electrostatic dust removal part passes through the magnetic adsorption part can dismantle fixed mounting in mounting groove 5.

In order to further prevent dust, wherein, electrostatic precipitator part includes two sets of negative pole framves 6, sets up multiunit conductive wire 7 and the cover between two sets of negative pole framves 6 and establishes the electrically conductive section of thick bamboo 8 in conductive wire 7 outside, and conductive wire 7 is the wire, fixedly connected with multiunit discharge piece 11 on the conductive wire 7, and the both ends of discharge piece 11 are the toper structure, through the toper structure, let the corona discharge function that the wire produced to produce the electrostatic field and adsorb the dust.

In order to further prevent dust, wherein, be equipped with multiunit through-hole 9 on the electrically conductive section of thick bamboo 8, conveniently adsorb the dust, negative pole frame 6 and the negative pole electric connection who sets up the power in the external world, electrically conductive section of thick bamboo 8 passes through wire ground connection, and the both ends of electrically conductive section of thick bamboo 8 are open structure, and electrically conductive section of thick bamboo 8 is iron plate and makes.

In order to let the installation of electrostatic precipitator part, wherein, the magnet adsorption part include with one of them negative pole frame 6 fixed connection's insulating seat 12, fixed connection is iron sheet 13 and the electro-magnet 14 of fixed connection on mounting groove 5 upper portion on insulating seat 12, insulating seat 12 is used for insulating iron sheet 13 and negative pole frame 6, when installing negative pole frame 6, energize electro-magnet 14, then let iron sheet adsorb on electro-magnet 14, so alright install, during the dismantlement, only need the outage can, can carry out the dismouting to negative pole frame 6, make things convenient for the maintenance arrangement in later stage.
