When driving a loudspeaker, you connect a power amplifier to the speaker using speaker wire. This speaker wire conducts electricity to the loudspeaker. The electricity is then connected onto the voice coil. The voice coil itself is suspended in a magnetic field. When currents are excited in that voice coil, there’s a mechanical force. This mechanical force then pushes the diaphragm within the magnetic field.
The advantage of dynamic speakers is that they are easy to construct. However, this type …
