B1Inside a micro speaker

Five parts, one clear sound.

Simplified cross-section for illustration, not a specific BESTAR part.

01 · Cover
Protects and tunes
The grille guards the diaphragm and shapes how sound leaves the part.
02 · Diaphragm
Moves the air
A light, corrugated film pushes the air to make sound.
03 · Voice coil
Turns current into motion
The audio signal flows through the coil attached to the diaphragm.
04 · Magnet
Creates the field
The coil moves in the magnet's field, driving the diaphragm back and forth.
