Horn Speaker Our horn speaker are mainly formed into a conical shape for better sound amplification and sound transmission. Our horn speakers are mainly used outdoors, often used in pa system or paga system. This is a fixed-resistance speaker. The distance between the speaker and the amplifier is no more than 10M. How do you want to use the speaker at a long distance such as the tunnel? In transmission, you need to use a constant voltage horn speaker. How do speaker horns work? A speaker horn is actually a kind of conversion device that converts electrical energy into sound. When different electron energy is transmitted to the coil, the coil generates an energy that interacts with the magnetic field of the magnet. This interaction causes the paper tray to vibrate because the electron energy changes at any time. The coil of the horn will move forward or backward, so the horn of the horn will follow the movement, which causes the density of the air to change and produce sound. The main principle is to use the left-hand theorem in physics, using the electromagnetic principle to cause vibration of the film and to make sound.
