Switchable Audio Cable for Bidirectional Signal Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio cables are limited to either input or output functions, requiring users to possess two separate cables for different usage scenarios, which can lead to confusion and increased costs due to similar appearances.
Innovation Solution
An audio cable with a switchable transmission direction, featuring a switch module that allows the same cable to function as both an input and output by controlling the connection states of its interfaces, enabling it to adapt to various usage scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users prepare two different audio cables for input and output functions, then the audio transmission functionality is complete, but the device complexity and user confusion increase due to similar appearances
Solution Approach 1:
The audio cable incorporates a switch module that enables a single cable to perform both input and output functions by changing the switching state, allowing the same physical cable to adapt to different transmission directions and eliminate the need for separate cables
2Device complexity
If a single audio cable is used for both input and output, then the device complexity is reduced, but the transmission direction control becomes necessary
Solution Approach 1:
The audio cable incorporates a switch module that enables dynamic reconfiguration of the transmission direction, allowing the cable to adapt its functionality from input to output mode through a simple switching operation, making the cable flexible and adaptable to different usage scenarios

AI summary
An audio cable with switchable transmission direction, includes an audio cable line. One end of the audio cable line is provided with a first interface for connecting with an audio device, and other end of the audio cable line is provided with a second interface for connecting with a terminal device. A switch module is arranged at a middle part of the audio cable line. The switch module is electrically connected with the first interface and the second interface. When the switch module is located at a first position, the audio cable line features a function of inputting audio signals from an audio device to a terminal device; when the switch module is located at a second position, the audio cable line features a function of outputting the audio signals from the terminal device to the audio device.
