SPEAKER [WITH Bose®, WITH CENTER DISPLAY]
Purpose
-
Converts the audio signal from the tuner and amp unit (TAU) 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 bass-box (speaker for lower register sound range).

Construction
Door speaker
-
A cone-shaped dynamic speaker has been adopted for each speaker.
-
A weight reduction was achieved by adopting pulp for the cone material and a ferrite magnet.
Driver-side headrest speaker/passenger-side headrest speaker
-
A cone-shaped dynamic speaker has been adopted for each speaker.
-
A weight reduction was achieved by adopting paper for the cone material and a ferrite magnet.
Tweeter
-
A weight reduction was achieved by adopting polyimide for the cone material and a neodymium magnet.
Woofer
-
A weight reduction was achieved by adopting pulp for the cone material and a ferrite magnet.
-
A better sound effect is achieved by the use of speakers which differ the range of the output sound.
-
Door speaker (speaker for all sound ranges)
-
Headrest speaker (speaker for all sound ranges)
-
Tweeter (speaker for medium-to-high-sound range)
-
Woofer (speaker for deep bass sound range)
Operation
-
The speaker sends the audio signal (current) from the audio unit to the voice coil.
-
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.
-
Because the voice coil is wrapped around the voice coil bobbin, the voice coil bobbin vibrates when the voice coil vibrates.
-
When the voice coil bobbin vibrates, the cone (diaphragm) installed to the voice coil bobbin vibrates and generates sound.
