Problems solved by technology

However, this arrangement has the disadvantage of leaking from the trunk into the cabin due to porous or flexible materials of construction and thus poor sound quality
Another arrangement in the prior art is to use an infinite baffle topology with access to outside air, but due to the size and shape of the loudspeaker assembly, this arrangement is limited to a limited number of possible locations where the loudspeaker assembly can be installed

Embodiment Construction

[0025] definition

[0026] Cabin refers to the passenger room or listening environment within a vehicle.

[0027] Common enclosures are enclosures with one or more speaker compartments.

[0028] Compartment walls include walls constructed from a single panel as well as double-panel walls constructed from an inner skin and an outer skin with a cavity therebetween, and may include floors, roofs, fire walls, side walls, or any perimeter boundary that interfaces with the external environment .

[0029] Inner skin refers to the compartment side panels of the double-panel wall, and may include steel panels, composite polymer panels, steel panels with fabric liners, and the like.

[0030] The skin refers to the panels of the double-panel wall that interface with the air outside the vehicle, and are most commonly made of steel.

[0031] figure 1 is a schematic cross-sectional view of a vehicle A showing a speaker assembly B installed in the vehicle A according to the present inven...

Abstract

A speaker assembly for use in a vehicle including a cabin and one or more cabin walls, the speaker assembly including a plurality of drivers fitted to a common enclosure including a vent tube that travels through the cabin walls of the vehicle, the speaker assembly is configured such that one side of the speaker assembly is in acoustic communication with a volume of air outside the cabin of the vehicle and the other side of the speaker assembly is in acoustic communication with air within the cabin of the vehicle.

Description

[0001] field of invention [0002] The present invention relates to low frequency loudspeakers (woofers and subwoofers) for use in vehicles. Background technique [0003] Space for speakers in a vehicle is very limited, so woofers and subwoofers need to be able to fit into small or irregular spaces. Additionally, the speaker assembly needs to be small compared to the enclosure of a typical woofer or subwoofer to minimize cost and weight. Attempts have been made to overcome this problem. One arrangement in the prior art is to use the trunk of the vehicle as the housing for the speaker assembly. However, due to the porous or flexible materials of construction, this arrangement has the disadvantage of leaking from the trunk into the cabin and thus poor sound quality. Another arrangement in the prior art is to use an infinite baffle topology with access to outside air, but due to the size and shape of the loudspeaker assembly, this arrangement is limited to a limited number of ...
