AI Technical Summary

Benefits of technology

The present invention relates to an electronic device (headrest) for vehicles. Each headrest has its own transducer that emits signals when it is pointed at by a vehicle's steering wheel. These signals help guide the driver towards their intended direction. By aligning these transducers correctly within the headrest itself, better performance can be achieved without causing any distortions during high-fidelity imagery.

Problems solved by technology

The technical problem addressed in this patent is how to create an improved automotive audio system that effectively addresses both listener and listener's own ear and headroom sounds while maintaining stability during different types of media playback.

Embodiment Construction

[0031]Turning now to FIGS. 2-7, the automotive audio system 290 of the present invention preferably incorporates a plurality of headrest assemblies (e.g., 200 or 500), each having a tripolar loudspeaker configuration which generates sound aimed along three distinct axes. Each automotive head-rest assembly 200 generates a selected three axis radiation pattern, which, in conjunction with selected inter-element delays and other design features, provides each passenger with temporal and amplitude cues for achieving a much more desirable effective and satisfying soundfield that is also appropriate for a wider variety of audio program material for an automobile's occupants.

[0032]In accordance with the method of the present invention, delivered sound is tailored or processed for each of the vehicle's occupants (e.g., driver vs passengers, front seat vs rear) as described further below (and illustrated in FIGS. 6A-6E).

[0033]FIG. 2 is a schematic depiction of the vehicle audio system of the pre

Abstract

A signal processing method and Automotive Audio System 290 comprising a tripolar loudspeaker configuration housed in at least one automotive head-rest assembly 200 or 500, whose radiation pattern, in conjunction with inter-element delays and other design features, is such that that passengers are afforded temporal and amplitude cues for achieving the desired soundfield appropriate for a variety of audio program material. Optionally, some or all of the headrest assembly transducers are aligned and configured with a Floating Waveguide member 470.
