MAZDA ERA-GLONASS SPEAKER
id092200043500
Purpose
• Converts the audio signal from the Mazda ERA-GLONASS control module to sound.
Functions
• Full-range speakers, which can output wide-range sound from low to high frequency, have been adopted.
Construction
• The Mazda ERA-GLONASS speaker is located centrally inside the instrument cluster.
• A cone-shaped dynamic speaker has been adopted for the Mazda ERA-GLONASS speaker.
Operation
1. The Mazda ERA-GLONASS speaker sends an audio signal (current) from the Mazda ERA-GLONASS control module to the voice coil.
2. When the audio signal (current) is sent to the voice coil, the coil is magnetized and a magnetic field is generated. 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.
