Display Sound Guide Channel for Slim 360° Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current displays with sound emitting devices face challenges in maintaining a slim appearance design while achieving desired sound field effects, as external speakers occupy space and disrupt the aesthetic, and the sound emitting direction often does not align with the thin or ultra-thin design.
Innovation Solution
The integration of a sound emitting device within the display's rear space, utilizing a sound box, speaker unit, and sound guide channel that directs sound downward and forwards through a non-parallel sound guide channel, reducing the vertical space requirement and maintaining the slim appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an external speaker unit is installed to increase sound emitting quality, then sound quality is improved, but the display occupies more surrounding space and makes the environment messy
Solution Approach 1:
The patent combines the speaker unit with the display device by integrating it into the rear case, making the speaker part of the display structure rather than an external component. This merging eliminates the need for separate speaker space while maintaining sound quality.
Solution Approach 2:
The speaker unit is nested within the rear case of the display device, utilizing the internal space of the display structure. The speaker is positioned in the rear case without protruding outward, effectively hiding it within the display's own volume.
2Reliability
If the sound emitting direction is changed to achieve 360° surround sound effect, then sound field effect is improved, but the speaker unit does not match the thin or ultra-thin appearance design
Solution Approach 1:
The patent changes the sound emitting direction from the traditional forward direction to the downward direction, utilizing the vertical dimension. The sound guide channel directs sound downward toward the support leg, creating a new sound propagation path that maintains the thin profile while achieving surround sound effects.
Solution Approach 2:
The support leg acts as an intermediary element that reflects sound from the downward-facing speaker. By positioning the speaker to face downward and using the support leg as a sound reflector, the system achieves 360° sound distribution without requiring the speaker to protrude or change the display's thin appearance.
3Shape
If the speaker unit faces downward to maintain slim design, then appearance is maintained, but sound propagation direction must be changed
Solution Approach 1:
The support leg serves as a sound reflector that redirects sound from the downward-facing speaker toward the viewer. This intermediary element solves the problem of sound propagation by reflecting sound upward and outward, making the downward-facing configuration effective for sound distribution.
Solution Approach 2:
The patent utilizes the downward vertical direction for sound emission, then employs the support leg to reflect sound in multiple horizontal directions. This dimensional approach allows the speaker to face downward while still achieving omnidirectional sound coverage through reflection.
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
Enables the installation of a sound emitting device without increasing the display's size or sound outlet area, achieving desired sound field effects like 360° surround sound and high sound quality while maintaining a slim design.
Implementation Method 1
The sound guide channel is extended to the sound emitting surface and has a sound outlet facing a second direction. The first direction is not parallel to the second direction.
