[0002] In audio systems, a "connection board" usually refers to a way to centrally power or connect multiple audio devices (such as speakers, amplifiers, decoders, etc.) through a connection board. The core purpose is to solve the problem of power supply requirements or signal transmission scalability of the devices. Traditional speaker junction boxes mostly have two connection points and are connected in parallel, which can lead to unstable power distribution and sound quality distortion. In addition, traditional junction boxes have poor waterproofing capabilities. When water gets into the junction box while it is powered on, it can easily cause short circuits or leakage, resulting in significant safety hazards and reduced safety performance when the junction box is used outdoors. Therefore, a waterproof speaker junction box with quick series connection is proposed. Utility Model Content
