Gas Pump Speaker Configuration with Downward Sound Redirection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gas pump multimedia displays often compromise on sound quality due to space constraints and lack of protection against moisture and foreign particles, failing to provide high-quality stereo sound to multiple listening areas effectively.
Innovation Solution
A speaker configuration with a pair of speakers positioned to direct sound downward from an audio and video housing supported by a stand, which can be retrofitted or integrated into gas pumps, using a trapezoidal design and perforated stands to enhance sound delivery and protect speakers from moisture and debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If speakers are exposed in the audio and video housing, then sound quality is improved, but speakers are vulnerable to moisture and foreign particles
Solution Approach 1:
The patent applies this principle by using perforated covers made of mesh material that allow sound to pass through while protecting speakers from moisture and foreign particles. The covers act as a barrier that maintains speaker protection without significantly compromising sound quality.
Solution Approach 2:
The patent uses porous mesh covers with perforations that allow acoustic waves to pass through while providing physical protection. The porous structure enables sound transmission while blocking harmful environmental factors from reaching the speakers.
2Manufacturing precision
If space is allocated for high-quality speakers in the audio and video housing, then sound quality is improved, but the housing size increases
Solution Approach 1:
The patent merges multiple functions into the speaker covers: they provide physical protection from elements, serve as acoustic transmission structures with perforations, and act as structural components of the housing. This consolidation allows high-quality speakers to be housed in a compact space without requiring additional protective structures.
3Adaptability or versatility
If existing gas pumps are retrofitted with audio and video housing, then multimedia capability is added, but installation complexity increases
Solution Approach 1:
The audio and video housing is designed as a universal unit that can be installed on existing gas pumps without requiring pump-specific modifications. The standardized housing design with integrated speaker protection and acoustic transmission features allows for straightforward retrofitting across different pump models, reducing installation complexity.

AI summary
A system and method for speaker configuration in an audio and video housing, wherein the audio and video housing may be supported by stands located on top of a gas pump. The audio and video housing may have an audio and video source, at least one video display, and circuitry to drive the pair of speakers. The speakers may have a covering to provide protection from moisture and foreign particles. The speakers may be positioned to output sound downward directed towards the top of a gas pump. The sound may then be redirected to a first and second listening area.
