SPEAKER [WITH Bose®, WITH CENTER DISPLAY]
id0920zz0103y4
Purpose
• Converts the audio signal from the audio unit to sound.
• High quality sound is provided for the driver and passengers.
Function
• Full-range speakers, which can output wide-range sound from low to high frequency, have been adopted.
• A better sound effect and clear sound have been achieved by using tweeters (speaker for upper register sound range) which differ the range of the output sound and front door speaker (speaker for lower register sound range).

Construction
Front door speaker, front center speaker
-
• A cone-shaped dynamic speaker has been adopted for each speaker.
• A weight reduction was achieved by using pulp for the cone material and adopting a neodymium magnet.
Rear door speaker, front side speaker, rear speaker
-
• A cone-shaped dynamic speaker has been adopted for each speaker.
• A weight reduction was achieved by using pulp for the cone material and adopting a ferrite magnet.
• A better sound effect is achieved by the use of speakers which differ the range of the output sound.
-
― Front door speaker (speaker for deep bass sound range)
― Rear door speaker (speaker for all sound ranges)
― Front center speaker (speaker for medium-to-high-sound range)
― Front side speaker (speaker for medium-to-high-sound range)
― Rear speaker (speaker for medium-to-high-sound range)
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.
