Solution Overview
Problem
Existing surround sound systems for home theaters are costly and difficult to install, and their performance is often compromised by the physical connection requirements and location constraints of equipment.
Innovation Solution
A method for transmitting audio signals from a television to mobile electronic devices within range, using a detecting module and wireless audio transmitter to synchronize audio playback, eliminating the need for additional equipment and allowing for flexible device placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surround sound equipment is physically connected to the television, then surround sound effect is achieved, but installation difficulty increases and location constraints are imposed
Solution Approach 1:
The patent replaces the mechanical connection system (physical cables and connections between television and surround sound equipment) with a wireless transmission system using electromagnetic signals. The television transmits audio signals wirelessly to mobile electronic devices, eliminating the need for physical connections while maintaining surround sound functionality. This substitution resolves the contradiction by removing installation complexity and location constraints associated with mechanical connections.
2Reliability
If additional surround sound equipment is purchased, then surround sound effect is achieved, but cost increases
Solution Approach 1:
The patent makes mobile electronic devices (smartphones, tablets, laptops) serve dual functions: their original purposes plus functioning as surround sound output devices. By utilizing the existing audio capabilities of universally owned mobile devices, the system eliminates the need for dedicated surround sound equipment, thereby reducing cost while maintaining the surround sound effect.
Solution Approach 2:
The patent creates a virtual copy of the traditional surround sound system using software and wireless transmission protocols on mobile devices instead of physical hardware. The mobile devices replicate the functionality of dedicated surround sound equipment through software-based audio processing and wireless reception, providing the same effect at lower cost.
3Reliability
If surround sound equipment is physically connected to the television, then audio signal transmission is achieved, but device mobility is restricted
Solution Approach 1:
The patent transforms the static, fixed-position audio transmission system into a dynamic, mobile system. Mobile electronic devices can freely move within the wireless signal transmission range of the television while continuously receiving audio signals. This dynamic approach maintains reliable audio transmission while providing complete placement flexibility, resolving the contradiction between transmission reliability and device mobility.

Data Source
AI summary
After a television transmits an audio signal, which is generated by decoding an audio stream, to a mobile electronic device located within a detectable range of the television in a wireless manner, the mobile electronic device plays the audio signal received from the television for fulfilling surround sound performance.
