The bass horn, tweeter, and midrange horn are combined to form a sound system. The sound is vibratory, with longer wavelength and lower frequency, which makes the human ear resonate and shock. It is used in wide places such as KTV, bars, and stages

The woofer is composed of an electromagnet, a coil, and a speaker film, which converts the frequency of the current into sound. The principle of physics is that when the current passes through the coil to generate an electromagnetic field, the direction of the magnetic field is the right-hand rule. Suppose that the speaker plays the C tone with a frequency of 256 Hz, that is, vibrates 256 times per second, and the speaker outputs 256 Hz alternating current. The current changes 256 times per second, and the C tone frequency is emitted. When the electric coil vibrates with the speaker membrane, pushing the surrounding air to vibrate, the speaker produces sound.

But because the human ear can hear the sound is limited (20Hz-20000Hz), so the general speaker will set the program within this range. Electromagnetic speakers are roughly composed of a power system (including: magnet, voice coil, or electric coil). Vibration system (including: sound film, which is horn diaphragm, dust cover, bomb wave), support system (including: basin frame, etc.). The working principle is the same as above. The energy conversion process is to convert electrical energy into magnetic energy, then from magnetic energy to mechanical energy, and then from mechanical energy to sound.
