Sound Bar For Mounting On A Recreational Vehicle Or Watercraft

Patent No. US11745669 (titled "Sound Bar For Mounting On A Recreational Vehicle Or Watercraft") was filed by Southern Audio Services Inc on Aug 9, 2022.

What is this patent about?

’669 is related to the field of sound bars , specifically those designed for use in recreational vehicles and watercraft. These environments present unique challenges, including the need for robust construction to withstand mechanical impacts, dustproof and watertight electrical components, and adjustable speaker directionality to compensate for open-air broadcasting and competing noises from the vehicle and wind.

The underlying idea behind ’669 is to create a sound bar that can be securely mounted to a recreational vehicle or watercraft while providing high-quality sound in challenging acoustic environments. This is achieved by combining a rugged, sealed enclosure with strategically positioned speakers and a rotatable mounting system that allows users to adjust the direction of the sound.

The claims of ’669 focus on a sound bar with an elongated housing containing an array of mid-range and tweeter speakers in the middle section, oriented to project sound outward from the longitudinal axis. A bass speaker is positioned at one end, emitting sound along the longitudinal axis. Crucially, the sound bar includes L-shaped mounting members that allow it to rotate around the longitudinal axis, enabling users to direct the sound as needed.

In practice, the sound bar is mounted to a vehicle or watercraft using the L-shaped mounting members. The user can then rotate the sound bar to optimize the direction of the sound based on their listening position and the surrounding environment. The sealed enclosure protects the internal components from dust and water, while the robust construction ensures that the sound bar can withstand the vibrations and impacts associated with off-road or marine use.

Unlike prior art sound bars, ’669 provides a simple and effective way to adjust the directionality of the sound. The rotatable mounting assembly allows for 360-degree rotation, giving users complete control over the sound projection. This is particularly important in open-air environments where sound can easily be lost or distorted by competing noises. The combination of robust construction, sealed components, and adjustable directionality makes ’669 well-suited for use in recreational vehicles and watercraft.

How does this patent fit in bigger picture?

Technical landscape at the time

In the late 2010s when ’669 was filed, sound systems for recreational vehicles often faced challenges related to durability, weather resistance, and sound quality in open environments. At a time when X was typically implemented using Y, systems commonly relied on Z rather than A, and when hardware or software constraints made B non-trivial.

Novelty and Inventive Step

The examiner approved the application because the prior art, including Martikainen, Chi, and Harms, discloses tubular speaker housings with L-shaped connection mechanisms. However, these references do not teach the specific mechanical limitations, speaker location, and orientation that enable the housing to be rotatable, which is a key feature of the claimed invention. The examiner found no motivation to combine these prior art references to achieve the claimed limitations.

Claims

This patent contains 10 claims, with claim 1 being independent. Independent claim 1 is directed to a sound bar for attachment to a recreational vehicle or watercraft, detailing its housing, speaker array, bass speaker, and mounting assemblies. The dependent claims elaborate on specific features and variations of the sound bar described in the independent claim, such as multiple speaker arrays, control modules, remote control functionality, and LED light strips.

Term (Source)Support for SpecificationInterpretation
Array of speakers
(Claim 1)
“Accordingly, a sound bar for attachment to a recreational vehicle or watercraft comprising an elongated hollow housing having a generally circular or polygon cross-section along a central longitudinal axis, and including a first end section and an opposite second end section separated by a middle section; the sections forming an interior passageway sized to contain (i) a first array assembly of mid-range and tweeter speaker units positioned in the middle section to emit sound in a direction outward from the central longitudinal axis”A group of speakers including midrange speakers, tweeters, or a combination of both, positioned in the middle section of the elongated housing and oriented to emit sound outward from the central longitudinal axis.
Bass speaker
(Claim 1)
“Accordingly, a sound bar for attachment to a recreational vehicle or watercraft comprising an elongated hollow housing having a generally circular or polygon cross-section along a central longitudinal axis, and including a first end section and an opposite second end section separated by a middle section; the sections forming an interior passageway sized to contain (ii) a first bass speaker unit positioned in the first end section to emit sound outward from a first end opening of the first section of the housing in a first direction generally along the central longitudinal axis, and (iii) a second bass speaker unit positioned in the second end section to emit sound outward from a second end opening of the second section of the housing in a second direction generally along the central longitudinal axis and opposite the first direction”A speaker positioned in one end of the elongated housing and oriented to emit sound outward from the elongated housing and in line with the central longitudinal axis.
First L-shaped member
(Claim 1)
“In another preferred embodiment the sound bar includes a first generally L-shaped leg member rotatable affixed to the first center hub area and a second generally L-shaped leg member rotatable affixed to the second center hub area; each L-shaped leg member comprising an elongated plate member having a hub receiving area positioned at a top end section of the elongated plate member, shaped to affix to its corresponding center hub area and having a shorter plate member affixed generally perpendicularly to the bottom end section of the elongated plate member.”A component of the first mounting assembly configured to secure the sound bar to a recreational vehicle or watercraft and rotably support the sound bar on a horizontal axis aligned with the central longitudinal axis of the elongated housing.
Second L-shaped member
(Claim 1)
“In another preferred embodiment the sound bar includes a first generally L-shaped leg member rotatable affixed to the first center hub area and a second generally L-shaped leg member rotatable affixed to the second center hub area; each L-shaped leg member comprising an elongated plate member having a hub receiving area positioned at a top end section of the elongated plate member, shaped to affix to its corresponding center hub area and having a shorter plate member affixed generally perpendicularly to the bottom end section of the elongated plate member.”A component of the second mounting assembly configured to secure the sound bar to a recreational vehicle or watercraft and rotably support the sound bar on a horizontal axis aligned with the central longitudinal axis of the elongated housing.
