Description

Technical Field

[0001] The invention belongs to the field of digital audio, and in particular relates to a waterproof diversion type digital audio. Background Art

[0002] Audio includes analog audio and digital audio. Analog audio is the representative of early audio. Its basic working principle is to amplify, process and reproduce sound signals through analog electronic circuits. Its sound quality is natural and easy to maintain, but the audio is large in size and has poor compatibility with digital audio signals. Digital audio is a type of audio that converts audio analog signals into audio digital signals, and restores digital signals to audio analog signals after transmission or storage. It is widely used in life because of its ability to accurately adjust audio parameters and good compatibility with digital media. The main structure of existing digital audio generally includes an external box and an internal speaker. A plurality of sound outlets are provided on the box, and the speaker discharges the sound through the sound outlets.
