Problems solved by technology

[0003] Most of the existing sound reinforcement equipment installed outdoors, such as those in landscape gardens, playgrounds, and open-air stadiums, only have the function of sound reinforcement, and rain and snow will inevitably occur in outdoor places, and rain and snow enter Going to the inside of the sound reinforcement equipment will affect the ability of the sound reinforcement equipment to convert electrical signals into acoustic signals, thereby affecting the service life of the sound reinforcement equipment; and the existing sound reinforcement equipment installed outdoors is mostly in a fixed form. It brings inconvenience to the movement and maintenance of the sound reinforcement equipment
