Audio Patch Cable Signal Rerouting for Voice Channel Elimination
Solution Overview
Problem
Existing audio patch cables fail to effectively modify audio signals to isolate specific channels, such as eliminating voice commentary in surround sound environments, leading to unintended audio consumption experiences.
Innovation Solution
The audio patch cable design includes a male connector with specific input contacts and a female connector with output contacts, utilizing conductive lines to reroute audio signals, allowing selective channel elimination, such as redirecting one channel to a reference signal, thereby isolating ambient sounds while suppressing commentary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standard audio patch cable is used to transmit surround sound signals, then all audio channels are transmitted faithfully, but the user cannot selectively eliminate specific channels such as voice commentary
Solution Approach 1:
The patent extracts and eliminates specific audio channels (such as voice commentary) from the surround sound signal by selectively connecting certain input contacts to output contacts while leaving other channels disconnected. This allows the user to remove unwanted channels while maintaining the overall audio signal transmission capability.
Solution Approach 2:
The audio patch cable is designed with multiple input contacts and output contacts that can be configured in different ways. The same cable structure can eliminate different channels depending on how the conductive lines are connected, providing multi-functionality for various audio channel elimination needs without requiring multiple specialized cables.
2Adaptability or versatility
If conductive lines are added to reroute signals for channel elimination, then selective channel elimination is achieved, but the cable structure becomes more complex
Solution Approach 1:
The cable's conductive lines are segmented into separate, independently configurable connections between input and output contacts. Each conductive line can be individually routed to achieve different channel elimination configurations, allowing complex signal routing to be achieved through simple modular connections rather than a monolithic complex structure.

AI summary
An audio patch cable includes a male connector end with a tip for a first audio signal, a ring for a second audio signal, and a sleeve. A first input contact is connected to the tip. A second input contact is connected to the ring. A third input contact is connected to the sleeve. A female connecter end is coupled to the male connector end. The female connector end includes: a first output contact, a second output contact, a third output contact, and a female plug. A first conductive line is connected to the first input contact and to the third output contact. A second conductive line is connected to the second input contact and to the first output contact and to the second output contact.
