In this video, we see a close-up of a homemade speaker system. The speaker is attached to a wooden base, and there are wires connected to it. The wires are connected to a circuit board, which is also connected to a battery. The circuit board has several components on it, including a switch and a potentiometer. The speaker is connected to the circuit board with a red wire. The video shows the speaker in action, producing sound as the wires are connected to the circuit board. The wooden base appears to be handmade, and the components on the circuit board are arranged in a way that suggests it is a DIY project. The video does not show any text or subtitles.
