Display Apparatus Sound Mode Switching via Wired Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display apparatuses are limited in providing surround sound or stereophonic sound to users, as external sound apparatuses can only output sound through one channel when paired, leading to potential sound data loss and limitations in sound quality.
Innovation Solution
A display apparatus and method that includes a display panel, a sound output apparatus, and an input/output interface for connecting external sound apparatuses via wire or wirelessly, allowing for multiple sound modes based on connection type, enabling stereo, surround, or stereophonic sound output through internal and external sound sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external sound apparatus is paired with display apparatus, then wireless connectivity is achieved, but sound data loss occurs during pairing
Solution Approach 1:
The patent applies preliminary action by performing sound output during the pairing process between display apparatus and external sound apparatus. The display apparatus continuously outputs sound through the external sound apparatus even while pairing operations are ongoing, ensuring that sound data is not lost during the connection establishment phase. This resolves the contradiction by maintaining the useful action (sound output) during the pairing process rather than waiting for pairing to complete.
2Device complexity
If external sound apparatus outputs sound through only one channel, then pairing simplicity is maintained, but surround sound and stereophonic sound capabilities are limited
Solution Approach 1:
The patent applies dynamics by enabling the external sound apparatus to dynamically switch between different sound output modes (stereo mode and surround sound mode) based on the connection state with the display apparatus. The system transitions from a static single-channel limitation to a dynamic multi-mode capability, allowing the external sound apparatus to adapt its sound output configuration according to operational requirements and connection status.
3Device complexity
If display apparatus uses only internal sound output apparatus, then device complexity is reduced, but sound quality and audio experience are limited
Solution Approach 1:
The patent applies universality by designing the display apparatus to support multiple sound output configurations through a single integrated system. The display apparatus can universally output sound through either the internal sound output apparatus, the external sound apparatus, or both simultaneously, depending on the selected sound mode. This multi-functional capability allows the system to adapt to different audio quality requirements without increasing fundamental device complexity.
