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 the 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 cabinet and an internal speaker. Multiple sound holes are opened on the cabinet, and the speakers discharge sound through the sound holes. However, when used in rainy days, rainwater often enters the cabinet through the sound holes, which will make the equipment unable to be used normally. For this reason, it is necessary to develop a waterproof structure for audio to improve the stability and scalability of audio. Summary of the Invention

The multiple drainage covers 52 are fixedly connected in series from top to bottom and connected by a series guide pipe 54. The lower end of the drainage cover 52 at the lower end is provided with a conduit 521, and the lower end of the conduit 521 is connected to the telescopic guide pipe 53. The lower end of the telescopic guide pipe 53 is connected to the lower inside of the positioning ring sleeve 4. The lower drainage pipe 55 is installed on the lower outside of the positioning ring sleeve 4 and extends to the lower outside of the accommodating box 2. The upper end of the lower drainage pipe 55 is connected to the lower end of the telescopic guide pipe 53 through the lower opening of the positioning ring sleeve 4; the rotating rod 51 is rotatably installed on the upper side of the accommodating box 2, and the rotating rod 51 drives the multiple drainage covers 52 to float up and down, so that the multiple drainage covers 52 move up and down on the inner side of each sound hole 31.

[0024] like Figures 1 to 7 As shown, in order to drive the multiple drain covers 52 to move up and down by the rotating rod 51, a transmission assembly 6 is further included; the transmission assembly 6 includes an adjustment block 61 and an upper guide rod 62; a longitudinal guide rail 21 is provided on the upper side wall of the inner front side of the accommodating box 2; the outer side of the adjustment block 61 slides up and down and is clamped on the longitudinal guide rail 21; the lower part of the rotating rod 51 is threadedly connected to the adjustment block 61; the upper side of the drain cover 52 located at the upper part is connected to the upper guide rod 521, and the upper end of the upper guide rod 521 is fixedly connected to the lower side of the adjustment block 61.
