Mazda CX-5 Service & Repair Manual: Speaker [Without Bose®]

Purpose

Specification

Construction

4 speaker type

• A cone-shaped dynamic speaker has been adopted for each speaker.

• Pulp for the cone material and a neodymium magnet have been adopted.

6 speaker type

• A cone-shaped dynamic speaker has been adopted for each speaker.

• Front door speaker/rear door speaker

• Pulp for the cone material and a neodymium magnet have been adopted.

• Tweeter

• Polyethylene naphthalene for the cone material and a strontium ferrite magnet have been adopted.

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

• Function not equipped.
