A method of creating in situ an acoustic enclosure in a space that is between body panels of a motor vehicle, wherein the space defines an empty volume, the method comprising placing into the space between body panels a molding tool that comprises a solid barrier that divides the space between body panels into an interior portion on an inside of the molding tool and an exterior portion that is external to an outside of the molding tool, where the outside of the molding tool is exposed to the space between body panels, and while the molding tool is in the space between the panels, introducing a fluid material into the exterior portion of the space between the body panels, wherein the fluid material is configured to cure into a solid shell.

Acoustic enclosure for motor vehicle

The technology can be embodied in a headrest that includes an enclosure that includes one or more acoustic transducers. The headrest includes a bar for mounting on a backrest of the seat, such that the mounted headrest is movable with respect to the backrest to different positions over an adjustable range. The bar includes one or more wires each of which is coupled to an electrical contact at one end, and an acoustic transducer at an opposite end, the one or more wires disposed within a hollow interior portion of the bar. The bar also includes an opening for permitting an electrical connection to be established between an electrical connector coupled to an external source, and the electrical contact coupled to the one or more wires. The connection is maintained over the adjustable range of the headrest by a mechanical bias on either the electrical connector or the electrical contact.

Connectors for speakers disposed in headrests

A communication system for a vehicle is described. The communication system includes a microphone array having a plurality of microphones mounted within the vehicle for receiving acoustic signals and converting the acoustic signals to electrical signals. An antenna is mounted proximate to the microphone array. The antenna communicates a radio frequency signal to a wireless device. The communication system also includes a controller having a first input that is electrically coupled to at least one microphone in the microphone array and a second input that is electrically coupled to the antenna. The controller processes the electrical signals and transmits the processed electrical signals to the antenna.

Vehicle communicating

An AM radio antenna circuit having a ferrite bar loop antenna comprises a resonating structure forming a balanced antenna circuit, a varactor diode tuning structure presenting a controllable capacitance to said winding structure, a DC path including the winding structure coupled to the varactor constructed and arranged to deliver a tuning signal to the varactor, and means for connecting the antenna circuit to the input of an external detector integrated circuit.
