Corner-Mounted Speaker Enclosure for Pontoon Watercraft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sound solutions for marine and recreational vehicles fail to achieve engineered sound, unobstructed sound sources, or design aesthetics due to inadequate speaker placement and lack of acoustical engineering.
Innovation Solution
An acoustical sound reinforcement system that utilizes corner locations in furniture to house sound devices in enclosures, generating zones of sound based on constructive interference gains, thereby providing premium sound systems with improved placement and acoustical control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If speakers are scattered throughout the listening area, then sound coverage is improved, but device complexity and aesthetic design are worsened
Solution Approach 1:
The patent combines multiple speakers into a single integrated enclosure unit that is mounted in one location (corner of furniture). This enclosure houses multiple sound producing devices that work together to provide comprehensive sound coverage, eliminating the need to scatter individual speakers throughout the listening area while maintaining aesthetic design.
2Power
If speakers are located near ankles, then sound output is improved, but obstruction by deck objects occurs
Solution Approach 1:
The patent positions the speaker enclosure in the vertical dimension (corner of furniture at height above deck) rather than at ankle level. This dimensional change in placement eliminates obstruction by deck objects while maintaining sound output power through the use of multiple speakers and acoustic engineering within the enclosure.
3Area of stationary object
If speakers are located in back rest area, then sound coverage is improved, but obstruction by occupants occurs
Solution Approach 1:
The patent relocates the speaker enclosure from the horizontal back rest area to a vertical corner position. This dimensional repositioning provides comprehensive sound coverage while eliminating obstruction by occupants who would block speakers in the back rest area.
4Power
If more speakers are added, then sound output is improved, but use of energy increases
Solution Approach 1:
The patent merges multiple speakers into a single enclosed unit with integrated acoustic engineering. This consolidation allows the speakers to work synergistically through constructive interference patterns, achieving enhanced sound output with more efficient energy usage compared to scattered speaker systems.
Solution Approach 2:
The patent employs acoustic engineering techniques that manipulate sound wave parameters (phase, amplitude, frequency) within the enclosure to create constructive interference zones. This parameter optimization allows multiple speakers to operate more efficiently, delivering enhanced sound output with reduced overall power consumption.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system delivers enhanced sound performance with better coverage, reduced obstruction, and increased output, allowing for deeper and richer low-frequency sound with less power consumption, thereby improving the audio experience in marine and recreational vehicles.
Implementation Method 1
generating at least one zone of sound based on constructive interference gains using the at least one sound device that may be in the enclosure
Data Source
AI summary
A system includes at least one sound producing device comprising at least one speaker stacked vertically and configured to be housed in a corner of furniture of a pontoon watercraft and generating constructive interference gains in at least one zone at a particular sound stage at a height above a deck of the pontoon watercraft.
