When the current through the voice coil according to Fleming's left
hand method, in the permanent magnetic field, the voice coil to do
the magnetic field line cutting movement, which drives the basin to
promote the surrounding air and sound.
How to determine the quality of speakers
First look at the speaker, and then through the speaker to confirm
the sound quality.
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.
