Switchable Sound Plate for Ultra-Slim TV Acoustic Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ultra-slim electronic devices, such as digital TVs, face challenges in maintaining sound quality due to the degradation of acoustic devices as they become thinner, as traditional speaker systems occupy volume and restrict slim designs, leading to vibration limitations and compromised sound playback.
Innovation Solution
An electronic device with a sound plate that is switchable between a stand type and a hang type, featuring a detachable speaker system with slits for sound emission in the stand type and front-firing in the hang type, allowing for ground plane radiation and reducing self-vibration, coupled with a parametric equalizer for optimized sound processing.

Engineering Contradiction Analysis
1Length of moving object
If traditional speaker systems are used in ultra-slim electronic devices, then the device structure becomes slim, but sound quality degrades due to vibration limitations and restricted acoustic space
Solution Approach 1:
The speaker system is segmented into a detachable sound plate module that can be separated from the main body. This allows the main body to remain ultra-slim while the sound plate provides adequate acoustic space for quality sound reproduction. The segmentation enables independent optimization of both slim profile and acoustic performance.
Solution Approach 2:
The sound plate is designed to extend in a direction perpendicular to the main body surface, utilizing the vertical dimension rather than increasing horizontal footprint. This allows the device to maintain a slim profile in the primary plane while providing sufficient depth in the perpendicular direction for proper speaker operation and sound emission.
2Ease of manufacture
If the sound plate is designed with fixed sound emission structure, then manufacturing is simplified, but adaptability to different mounting arrangements (stand type and hang type) is reduced
Solution Approach 1:
The sound plate incorporates a detachable coupling mechanism that allows it to be dynamically repositioned between stand type and hang type arrangements. The coupling unit can be selectively engaged or disengaged, enabling the sound plate to adapt its orientation and sound emission direction based on the mounting configuration, thus providing versatility without complicating the basic structure.
Solution Approach 2:
The sound plate is designed with universal coupling interfaces that accommodate both stand type and hang type mounting arrangements. The same sound plate structure serves multiple functions by being adaptable to different orientations and mounting positions, eliminating the need for separate designs for each mounting type.
3Adaptability or versatility
If the sound plate is made detachable for flexible arrangement, then adaptability to different mounting types is improved, but device complexity increases
Solution Approach 1:
The coupling mechanism is segmented into simple, modular components that attach to the sound plate and main body separately. This segmentation allows each component to perform a specific function with a simple structure, and the overall complexity is managed through modular assembly rather than a complex integrated mechanism.
Solution Approach 2:
The detachable coupling unit employs simple engagement and disengagement mechanisms that provide dynamic reconfigurability without requiring complex locking or actuation systems. The coupling allows the sound plate to be easily attached or removed based on mounting requirements, achieving adaptability through straightforward mechanical means.

The solution enables ultra-slim electronic devices to maintain sound quality similar to front-firing speakers, improve sound playback and articulation, and reduce vibration issues, while providing superior low-frequency extension and high-frequency range recording through adapted equalization.
Implementation Method 1
the sound plate emits the sound through at least one slit provided on a side surface of the flat plate, and in the second arrangement the sound plate emits the sound through an opening provided on a front of the flat plate
Implementation Method 2

AI summary
An electronic device includes a sound plate switchable between a stand type and a hang type. In the electronic device, the sound plate has a coupled structure movable between a first arrangement, in which the sound plate functions as a stand and a second arrangement wherein the sound plate is disposed at the rear of a main body as a hang type. In the first arrangement, the sound plate emits a sound through a slit provided in a side surface of the sound plate, and in the second arrangement, the sound plate emits sound through an opening in a front surface of the sound plate which is perpendicular to the side surface of the sound plate.
