The speaker's function is to convert electrical signals into audio
signals, so their performance is completely different,they are the
utility model has the opposite function.
The current audio voice coil induces a N pole and S pole changing
alternating magnetic field and magnetic circuit of loudspeaker
system N pole, S pole fixed magnetic field interaction, the voice
coil vibrates, which led to stick to the voice coil drum paper and
vibration, promote the air to produce sound.
