Abstract: A device and method that is configured to control the operation of a motor vehicle cabin active sound management (ASM) system that uses an ASM controller to control operation of one or more sound transducers that transmit audio signals in the cabin so as to alter vehicle powertrain-related sounds in the cabin, wherein the motor vehicle further comprises a mobile telephone system that is configured to receive incoming mobile telephone calls and transmit outgoing mobile telephone calls. The device can include a controller that is configured to receive from the mobile telephone system an indication that a mobile telephone call is incoming or an outgoing call is being initiated. After receiving the indication, the subject controller commands the ASM controller to cause operation of one or more sound transducers such that the level of vehicle powertrain-related sounds in the cabin is reduced.

Abstract: A vehicle loudspeaker system is provided. The system includes a vehicle body having a trunk floor pan, and a trunk floor that covers the trunk floor pan. The trunk floor has an upper surface and an opposite, lower surface. An electro-acoustic transducer is disposed between the lower surface of the trunk floor and the trunk floor pan. The transducer includes a diaphragm that defines a first radiating surface and a second radiating surface that is opposite the first radiating surface. The electro-acoustic transducer also includes an electro-magnetic motor for driving motion of the diaphragm along a motion axis. The transducer being arranged such that motion axis is within 45 degrees of parallel with the trunk floor. The system also includes a duct that is configured and arranged to direct acoustic energy radiated from the first radiating surface to a region above the upper surface of the trunk floor.
