In-cabin acoustic-based passenger occupancy and situation state assessment

Techniques are disclosed to use existing vehicle speakers alone or in conjunction with other sensors (e.g. SRS sensors and/or microphones) that may already be implemented as part of the vehicle to identify acoustic signatures. Suitable low-cost and widely available hardware components (e.g., relays) may be used to modify the vehicle's existing speakers for a bi-directional mode of operation. Moreover, the vehicle's existing of audio amplifiers may be used to amplify signals collected by the speakers when operating in “reverse,” and process these collected signals to determine vehicle state information.

Low-Profile Panel Assembly for Providing Sound Within a Passenger Compartment of a Vehicle

A low-profile panel assembly configured to provide sound having at least one acoustic wavelength within a passenger compartment of a vehicle is provided. The vehicle has a support structure. The assembly includes a substrate panel perforated with at least one sub-wavelength hole which extends between front and back surfaces of the panel. The panel is configured to be attached to the support structure. A continuous membrane of facing material overlies and is in contact with the panel. The membrane is tightly stretched over and covers the at least one hole at the front surface of the panel. An electroacoustic sound source is configured to radiate acoustic waves against the back surface of the panel. The radiated acoustic waves travel through the at least one membrane-covered hole to vibrate at least one portion of the membrane which tightly covers the at least one hole. The at least one vibrating portion of the membrane radiates acoustic waves into the passenger compartment of the vehicle.
