Vehicle loudspeaker module
First Claim
1. Apparatus comprising:
- an audio module for use in a vehicle cabin, comprising;
an elongated substantially sealed enclosure having two ends in the lengthwise direction;
a first acoustic driver mounted in the enclosure near one end of the enclosure for radiating acoustic energy from the one end of the enclosure;
a second acoustic driver mounted in the enclosure near a second end of the enclosure for radiating acoustic energy from the second end of the enclosure; and
a bass augmenting device for radiating low frequency acoustic energy from the enclosure,wherein the audio module is constructed and arranged to be pre-assembled so that the audio module can be installed in the vehicle as a single assembly,wherein the audio module is configured to be mounted to the vehicle so that the lengthwise direction is substantially vertical with the first end of the enclosure higher than the second end of the enclosure,wherein the bass augmenting device is closer to the second end of the enclosure than to the first end of the enclosure,wherein the vehicle cabin is configured so that there is an acoustic null of radiation from the first acoustic driver at a predetermined position in the vehicle cabin in a predetermined frequency range, the apparatus comprising circuitry to cause the second acoustic driver to radiate in the predetermined frequency range and to roll off radiation from the second acoustic driver above and below the frequency range, andwherein the first acoustic driver and the second acoustic driver are substantially full range acoustic drivers, and wherein the frequency range of the acoustic null is at about 90 Hz to about 120 Hz.

Abstract
An audio module for use in a vehicle cabin. An elongated substantially sealed enclosure has two ends in the lengthwise direction. A first acoustic driver is mounted in the enclosure near one end of the enclosure for radiating acoustic energy from the end of the enclosure. A second acoustic driver is mounted in the enclosure near a second end of the enclosure for radiating acoustic energy from the second end of the enclosure. The audio module includes a bass augmenting device for radiating low frequency acoustic energy from the enclosure. The audio module is constructed and arranged to be pre-assembled so that the audio module can be installed in the vehicle as a single assembly. The audio module is configured to be mounted to the vehicle so that the lengthwise direction is substantially vertical with the first end of the enclosure higher than the second end of the enclosure.
