Display Device Audio Switching for Private Continuous Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices struggle to provide sound selectively to connected external audio devices while maintaining privacy and continuity of content viewing, especially during events like calls or interactions in virtual reality environments.
Innovation Solution
A display device with a communication interface and processor that switches between modes based on connection to external audio devices, controlling sound output to the external device or internal speakers, and managing sound based on control signals, selection signals, and user interactions.

Engineering Contradiction Analysis
1Object-affected harmful factors
If sound is output through internal speakers, then privacy is compromised, but if sound is output through external audio devices, then connection reliability must be maintained
Solution Approach 1:
The system dynamically switches between first mode (internal speakers) and second mode (external audio devices) based on connection status. When an external audio device is connected, the system operates in second mode to provide private sound output. When disconnected, it switches to first mode, ensuring continuous operation without interruption while maintaining privacy when possible.
Solution Approach 2:
The system continuously monitors connection status through the communication interface and uses this feedback to determine operation mode. The processor receives connection status information and automatically adjusts the sound output path, ensuring reliable transition between private and non-private modes based on real-time connection conditions.
2Object-affected harmful factors
If the system switches between modes based on external device connection, then sound quality and privacy are improved, but system complexity increases
Solution Approach 1:
The display device is designed with multi-functionality, incorporating both internal speakers and external audio device connectivity within a single system. The processor and communication interface enable the device to perform multiple functions: local sound output, wireless communication, and automatic mode switching, reducing the need for separate systems.
Solution Approach 2:
The communication interface acts as an intermediary between the processor and external audio devices. It manages the connection status information and facilitates automatic mode switching, simplifying the control logic by centralizing connection management in a dedicated interface component.
3Speed
If sound output is stopped in response to control signals, then responsiveness is improved, but content viewing continuity may be interrupted
Solution Approach 1:
The system dynamically adjusts sound output based on control signals while maintaining content display. When a control signal is received, the system quickly stops or mutes sound output through the external audio device, providing immediate responsiveness. The display continues to show content without interruption, maintaining viewing continuity while managing audio output flexibly.

AI summary
A display device includes a display, a speaker; a communication interface; memory storing instructions; and at least one processor, wherein the instructions, when executed, cause the display device to determine whether an external audio device is connected via the communication interface; based on the external audio device not being connected, operate in a first mode that displays a first image corresponding to content and outputs, via the speaker, a first sound corresponding to the content; based on the external audio device being connected, operate in a second mode that displays the first image and outputs the first sound from the external audio device via the communication interface; and based on operating in the second mode, in response to receiving a first control signal to stop outputting the first sound, display the first image, stop outputting the first sound via the communication interface, and mute the first sound.
