Description

A rotary dust removal device for computer audio

technical field

The invention relates to the field of dust removal equipment, in particular to a rotary dust removal device for computer audio.

Background technique

Sound refers to sounds other than human language and music, including sounds from the natural environment, animals, machines and tools, and various sounds from human actions. Audio probably includes power amplifiers, peripheral equipment (including compressors, effects, equalizers, VCD, DVD, etc.), speakers (speakers, speakers), mixers, microphones, display devices, etc. add up to a set. Among them, speakers are sound output devices, speakers, subwoofers and so on. A speaker includes high, low, and medium speakers, three but not necessarily three. The development history of technology can be divided into four stages: tube, transistor, integrated circuit, and field effect tube.

To be precise, it is the integrated audio set machine launched by the manufacturer, which has as many functions as possible, is easy to use, and has a gorgeous appearance. All the components of the combined audio system, such as speakers, power amplifiers, decks, and CD holders, are provided by one manufacturer. It takes a lot of time to debug, and generally speaking, it can be used directly, which is more convenient in operation and relatively complete in functionality.
