Abstract

A vehicle installation structure (1) for attaching to a vehicle panel (3), comprises an air extraction duct (4) which has a first duct part (41) and a second duct part (42) adjacent to the first duct part (41), and which is configured to extract air (50) from an inner space (V3) to an outside space (V2) of a vehicle through the first duct part (41) and second duct part (42), a loudspeaker device (2) configured to face a first side (31) of the vehicle panel (3) and comprising a housing (21) and an air communication duct (22) which is configured to be attached to the vehicle panel (3) and to connect an inner space (V1) of the housing (21) to a space (V2) facing a second side (32) of the vehicle panel (3) which is opposite the first side (31) through an opening (33) in the vehicle panel (3). At least a portion of the first duct part (41) and at least a portion of the air communication duct (22) are formed by a common duct (60), and the second duct part (42) has a first end (421) and a second end (422), wherein the first end (421) opens into the air communication duct (22) and the second end (422) is configured to open into the inner space (V3) of the vehicle, and the second duct part (42) is at the first end (421) acoustically closed at least at a frequency band at which the loudspeaker device is configured to operate while air (50) is extractable from the inner space (V3) to the outside space (V2) through the first duct part (41) and second duct part (42).
