Why does the horn sound?

The general speaker is composed of iron frame, magnet and paper basin. A coil is installed in the middle of the paper basin and glued. The coil works in the gap of the magnet, and there is a magnetic field in the gap of the magnet. When the coil in the middle of the paper basin passes through the audio current, the coil will also generate a magnetic field that changes with the strength of the audio current. This magnetic field interacts with the inherent magnetic field of the magnet, making the coil move accordingly, and driving the paper basin to move and make sound. In short, the speaker is a kind of energy conversion.
The horn is composed of three parts: vibration system, magnetic circuit system and support system
The vibration system includes voice coil, elastic wave and diaphragm.
The magnetic circuit system includes: U iron (T iron), magnet and Huasi.
Support system includes: basin frame, gasket, dust cover, terminal board and lead
The voice coil wound by the metal coil in a circular way generates electric energy through its conduction current, and the magnetic field polarity arrangement is generated through the conduction of the current. Then the right angle intersection force is generated by the current and the magnetic field, so that the voice coil acts up and down to push the diaphragm, and this instant expanding rhythm will cause the wave sound wave or air flow, and generate sound and make sound.
