Vehicle speakers convert electrical audio signals into audible sound waves within the cabin. Typically integrated into doors, dashboards, or rear decks, they utilize electromagnetic coils, diaphragms, and enclosures to reproduce frequencies across the audio spectrum. Key specifications include impedance (ohms), power handling (watts RMS/peak), sensitivity (dB), and frequency response range (Hz). Variations include component speakers, coaxial speakers, and subwoofers, each designed for specific frequency reproduction roles. Materials commonly used in construction are polypropylene, paper, silk, and metal alloys, impacting sound characteristics and durability.
