Abstract
A trim panel, e.g., a roof lining for a vehicle passenger compartment, characterized in that the trim panel comprises an integral acoustic radiator and a vibration exciter mounted on the radiator to launch bending waves into the radiator to cause it to resonate to produce an acoustic output. The acoustic radiator has a periphery which is integral with the radiator and the trim panel.

A vehicle having a passenger compartment, a trim panel (1) lining at least a portion of the passenger compartment and comprising opposed skins (8) enclosing and laminated to a core (9), and a loudspeaker in the trim panel (1) comprising an integral resonant acoustic radiator (5), a vibration exciter (6) mounted on the radiator (5) to launch bending waves into the radiator (5) to cause it to resonate to produce an acoustic output, and a radiator periphery (7) integral with the radiator (5) and the surrounding trim panel (1), the radiator (5) having outside the radiator periphery (7).
A trim panel (1) for a vehicle having a passenger compartment, the trim panel (1) comprising opposed skins (8) enclosing and laminated to a core (9), an integral resonant acoustic radiator (5) with a vibration exciter (6) mounted on the radiator (5) to launch bending waves into the radiator (5) to cause it to resonate to produce an acoustic output, and a radiator periphery (7, 16) integral with the radiator (5) and the surrounding trim panel (1), the radiator (5) having reduced thickness compared with the thickness of the trim panel (1) outside the radiator periphery (7, 16).
A vehicle having a passenger compartment, a trim panel (1) lining at least a portion of the passenger compartment and comprising opposed skins (8) enclosing a core (9), and a loudspeaker in the trim panel (1) comprising an integral resonant acoustic radiator (5), a vibration exciter (6) mounted on the radiator (5) to launch bending waves into the radiator (5) to cause it to resonate to produce an acoustic output, and a radiator periphery (7) integral with the radiator (5) and the surrounding trim panel (1), wherein part of the panel is compressed to form the radiator (5) such that the radiator (5) has reduced thickness compared with the thickness of the trim panel (1) outside the radiator periphery (7).
A trim panel (1) for a vehicle having a passenger compartment, the trim panel (1) comprising opposed skins (8) enclosing a core (9), an integral resonant acoustic radiator (5) with a vibration exciter (6) mounted on the radiator (5) to launch bending waves into the radiator (5) to cause it to resonate to produce an acoustic output, and a radiator periphery (7, 16) integral with the radiator (5) and the surrounding trim panel (1), wherein part of the panel is compressed to form the radiator (5) such that the radiator (5) has reduced thickness compared with the thickness of the trim panel (1) outside the radiator periphery (7, 16).
