Introduction of Speaker grill
A speaker grill is usually found in front of the earphone and loudspeaker which mounted directly over the face of the speaker driver. It maily used to protect the driver element, speaker internals and other audio components from foreign objects while still allowing the sound to clearly pass. However, because it sits in the direct path of the driver, the grille interacts with the sound produced. A suitable compromise between protection and sound quality must be made based on the speaker's application.
