Wall-Mounted Audio Speaker Layout for Direct Front Sound
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall-mounted audio devices suffer from poor sound quality due to speakers outputting sound towards the back, sides, or bottom, affecting the appearance and overall sound transmission, especially with thinner display screens, and the speaker arrangement disrupts the aesthetic appeal.
Innovation Solution
A wall-mounted audio device design featuring a detachable mesh covering the rim region, a speaker module hidden behind the display component, and a vibration isolation damping element to prevent vibration transmission, with symmetrical speaker modules and bass enhancement, ensuring high-quality sound output from the front while maintaining an attractive appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the speaker outputs sound toward the back, side, or bottom to achieve a front-facing appearance with a thinner display screen, then the appearance is improved, but the sound quality deteriorates due to attenuation and delay of middle to high frequencies
Solution Approach 1:
Instead of outputting sound toward the back, side, or bottom to achieve a front-facing appearance, the patent inverts the approach by placing the speaker module at the front of the display component so that sound outputs directly toward the listener. This inversion resolves the contradiction by maintaining both the front-facing appearance and high sound quality without attenuation or delay.
2Reliability
If the speaker module is arranged in separate regions with a through hole for sound output, then the sound transmission function is achieved, but the appearance becomes complex and less simple
Solution Approach 1:
The patent merges the speaker module with the display component by integrating the speaker module housing into the display component structure. The speaker module is positioned at the front of the display component with sound outputting directly toward the listener, eliminating the need for separate through holes and achieving both simple appearance and effective sound transmission.
3Length of moving object
If the display screen is made lighter and thinner to achieve a front-facing appearance, then the appearance is improved, but the speaker arrangement is constrained and sound quality deteriorates
Solution Approach 1:
The patent resolves the spatial constraint imposed by a thin display screen by positioning the speaker module in the front dimension of the display component, rather than attempting to route sound through the thin profile. This dimensional repositioning allows the speaker to output sound directly toward the listener without being constrained by the thinness of the display screen, maintaining both the thin profile and high sound quality.
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 design enhances sound quality by allowing direct sound transmission to the listener while beautifying the device's appearance, offering customizable mesh options and easy style changes, improving user experience and product playability.
Implementation Method 1
a vibration isolation damping element; and the vibration isolation damping element is arranged at a joint between the speaker module and the wall-mounted box body
Implementation Method 2
a mesh, wherein an area of the mesh is matched with an area of the rim region; and the mesh is detachably connected to the front panel of the wall-mounted box body
