Sound Guide Assembly Layout for Narrow-Bezel Front Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sound boxes in multimedia electronic devices often require a wide side frame to achieve optimal sound quality, which compromises the device's modeling effect and increases space usage, as sound outlets are typically positioned on the front, leading to occupied display regions or excessive frame width.
Innovation Solution
The implementation of a sound guide assembly with a sound guide device that includes a sound receiving portion and a sound guide body, where the sound receiving portion is connected to the sound box, and the sound guide body leads the sound to a sound outlet positioned on the same side as the display, allowing for a narrow frame design without compromising sound quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sound outlet is arranged on the front of the electronic apparatus, then the sound quality is significantly improved, but the display region is occupied or a very wide bottom frame needs to be reserved
Solution Approach 1:
The sound guide body extends in the thickness direction (depth dimension) of the electronic apparatus rather than only in the front horizontal plane. By utilizing the Z-axis dimension, the sound transmission path is created without occupying additional display area on the front surface, thus resolving the contradiction between sound quality and display region occupation.
Solution Approach 2:
The sound guide assembly is nested within the existing housing structure, with the sound guide body positioned in the space between the sound box and the front surface. This nested arrangement allows the sound transmission function to be integrated without requiring additional external space or occupying display region.
2Reliability
If the sound outlet is arranged on the front of the electronic apparatus, then the sound quality is significantly improved, but a very wide bottom frame needs to be reserved which affects the overall modeling effect
Solution Approach 1:
The sound transmission is achieved by extending the sound guide body in the thickness direction rather than expanding the frame width horizontally. This dimensional shift allows high-quality front sound output while maintaining a narrow frame width, thus improving the overall modeling effect.
3Volume of moving object
If a wide bottom frame is reserved for the sound box, then the sound box installation space is sufficient, but the overall space usage increases and modeling effect deteriorates
Solution Approach 1:
The sound guide body utilizes the thickness direction (depth) of the apparatus to provide adequate installation space for the sound box without increasing the horizontal footprint. This allows sufficient volume for sound box placement while maintaining a compact overall apparatus volume and narrow 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
This solution enables the electronic apparatus to maintain sound quality while achieving a narrow frame design by optimizing the sound guide assembly's geometry, allowing the sound outlet to be positioned on the side frame without increasing the overall volume or occupying display space.
Implementation Method 1
The sound guide body is configured to lead out a sound. An end surface of the sound receiving portion is provided with a sound inlet. A tail end of the sound guide body deviating from the sound receiving portion is provided with a sound outlet.
