Front Sound Guide Assembly for Narrow-Bezel Electronic Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound boxes in multimedia electronic equipment face challenges in achieving optimal sound quality and narrow frame design due to the need for increased side frame width or occupied display area when the sound outlet is positioned on the front.
Innovation Solution
A sound guide assembly with an L-shaped sound guide device that includes a sound input portion and a sound output portion, where the sound input portion is taller than the output portion, allowing the sound outlet to be positioned on the front without increasing the side frame width, and incorporating an equalizer with sound input holes and channels to enhance sound quality and directivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sound outlet is arranged on the front of the electronic equipment, then the sound quality is improved, but the side frame width must be increased or the display region is occupied
Solution Approach 1:
The patent introduces a sound guide device with a sound guide channel that extends in the thickness direction (depth dimension) of the electronic equipment. By guiding sound waves through this additional dimension rather than directly forward, the sound outlet can be positioned on the front while avoiding the need to increase side frame width or occupy display region space.
Solution Approach 2:
The sound guide device acts as an intermediary component between the sound box and the front sound outlet. It receives sound waves from the sound box positioned in the accommodating cavity and redirects them through the sound guide channel to the front sound outlet, enabling front sound projection without requiring the sound box to be positioned at the front.
2Volume of stationary object
If the sound outlet is arranged on the under side of electronic equipment, then the installation space is saved, but the sound quality is greatly affected due to ground reflection
Solution Approach 1:
Instead of directing sound waves downward (vertical dimension) where they would reflect off the ground, the sound guide device redirects them horizontally through the sound guide channel to the front sound outlet. This dimensional redirection allows the sound box to be positioned in the accommodating cavity (saving installation space) while maintaining sound quality by avoiding ground reflection.
3Reliability
If enough installation space is reserved for the sound box, then the sound quality is improved, but the display region is occupied or the bottom frame must be made very wide
Solution Approach 1:
The sound guide channel extends in the thickness direction of the electronic equipment, utilizing the depth dimension for sound wave propagation. This allows the sound box to be positioned in the accommodating cavity with sufficient installation space for good sound quality, while the sound outlet remains at the front without occupying display region area or requiring a wide bottom frame.
Applied Scientific Principles
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 solution enables improved sound quality and reduced frame width by guiding sound waves efficiently to the front while maintaining a narrow frame design, enhancing sound propagation and directivity without occupying display space.
