Samsung patents speaker design with groove to improve sound quality

Samsung has filed a patent for a speaker design that includes a specific groove in the metal part facing the moving diaphragm. This groove aligns with the coil to allow the speaker to move more freely when creating sound.

Why it mattersThis is a routine hardware improvement aimed at making the speaker components work more smoothly, which could lead to slightly better audio performance in future devices.

The coil may be disposed to make a surface thereof facing the yoke correspond to the avoidance groove and configured to linearly reciprocate the diaphragm by receiving an electric signal.
