Variable Length Soundbar With Adjustable Speaker Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional soundbars are often not the correct size for their environment, leading to inadequate audio output in either overpowering or underpowering small or large rooms, and they lack the ability to accommodate varying television widths with sufficient acoustic options.
Innovation Solution
A variable length soundbar system comprising leveling brackets, an elongated alignment bar, speaker mounting brackets, speakers, and a grille, allowing for customizable length and spacing to match any room or device width, with adjustable leveling and telescoping features for optimal acoustics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional soundbars are used, then the device structure is simple and easy to manufacture, but the soundbar length cannot be adjusted to match different television widths and room sizes
Solution Approach 1:
The soundbar is divided into modular components including adjustable leveling brackets, an elongated alignment bar, and multiple speaker mounting brackets that can be independently positioned. This segmentation allows the soundbar to be customized to different lengths while maintaining a relatively simple overall structure.
Solution Approach 2:
The soundbar incorporates adjustable leveling brackets with vertical screw levelers and stop screws that allow dynamic adjustment of the alignment bar position and speaker spacing. This dynamic adjustability enables the soundbar to adapt to different television widths and room sizes without requiring a completely complex reconfigurable structure.
2Adaptability or versatility
If frame extensions are added to provide variable lengths, then the soundbar can accommodate different television widths, but the speaker spacings are limited to a few discrete positions
Solution Approach 1:
The alignment bar is designed with pre-drilled mounting holes at multiple positions along its length, allowing speaker mounting brackets to be attached at various locations. This preliminary preparation of mounting positions enables flexible speaker spacing adjustment while simplifying the assembly process, as users can directly attach brackets at desired positions without complex calculations or modifications.
3Ease of manufacture
If a fixed number of speakers are used in variable length soundbars, then the manufacturing process is simplified, but the audio output is inappropriate for different room sizes
Solution Approach 1:
The soundbar system uses independently mountable speaker mounting brackets that can be attached at different positions along the alignment bar. This segmentation allows the number of speakers to be adjusted based on room size requirements, while each speaker unit remains a standardized component that simplifies manufacturing.
Solution Approach 2:
The alignment bar and speaker mounting brackets are designed as universal components that can accommodate different numbers of speakers at different positions. This multi-functionality allows the same basic structure to serve both small and large rooms by simply adjusting the number and position of speaker mounting brackets, without requiring different manufactured components.

AI summary
A variable length soundbar broadly comprising a number of leveling brackets, an elongated alignment bar, a number of speakers mounting brackets, a number of speakers, and a grille. The leveling brackets include a vertical screw leveler for leveling the elongated alignment bar and hence the speakers. The speaker mounting brackets are configured to be laterally spaced from each other on the elongated alignment bar. The speakers each include a number of drivers configured to output sounds of different frequencies. The grille is configured to at least partially cover the speakers. The grille and the elongated alignment bar are configured to be resized to a desired length.
