Abstract
A speaker system includes a first panel, a second panel, a third panel, a speaker unit, and a sound absorber. The first panel is an outer panel constituting a part of a vehicle door of a vehicle having a compartment. The second panel constitutes a part of the vehicle door and is situated closer to the compartment than the first panel and has an opening. The third panel constitutes a part of the vehicle door and resides between the first panel and the second panel. The speaker unit overlaps the opening in a plan view when viewed from the compartment along a central axis of the speaker unit and outputs sound toward the compartment. The sound absorber is arranged at a location corresponding to an anti-node of particle velocity in a standing wave generated in a space defined between the speaker unit and the first panel.
