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.

Fail-safe

  • Not applicable
