The pronunciation of the speaker is that the voice coil voltage vibrates under the action of magnetic steel, which drives the speaker basin to pronounce-the general circuit diagram only has the schematic diagram of the speaker, but there is no schematic diagram of the speaker. Because only the circuit diagram is needed to assemble the audio, and the schematic diagram of the speaker is not needed.

The wiring diagram of the loudspeaker is very simple-just connect the positive and negative poles of the power amplifier output to the positive and negative poles of the loudspeaker-there is a general loudspeaker circuit diagram, as shown in the following figure:
