Construction
4 speaker type
-
• Front door speaker/rear door speaker
Type A
-
― A cone-shaped dynamic speaker has been adopted for each speaker.
― Pulp for the cone material and a neodymium magnet have been adopted.
Type B
-
― A cone-shaped dynamic speaker has been adopted for each speaker.
― A weight reduction was realized by using pulp for the cone material and adopting a strontium barium ferrite magnet.

Operation
1. The speaker sends the audio signal (current) from the audio unit to the voice coil.
2. When the audio signal (current) is sent to the voice coil, the coil becomes magnetized and a magnetic field occurs. Because the voice coil and the magnet pull and repel each other in the magnetic field, the voice coil vibrates.
3. Because the voice coil is wrapped around the voice coil bobbin, the voice coil bobbin vibrates when the voice coil vibrates.
4. When the voice coil bobbin vibrates, the cone (diaphragm) installed to the voice coil bobbin vibrates and generates sound.
Fail-safe
• Function not equipped.
