Display Audio Mixer Circuit for Multi-Headset Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing displays, such as e-sports displays, typically have only one headphone jack, which is insufficient for connecting multiple headsets when multiple users play against each other, limiting audio signal distribution and communication.
Innovation Solution
The display is equipped with multiple audio connectors and a mixer and amplifier circuit that can broadcast audio signals to all connectors and switch input signals between them, allowing multiple headsets to connect and communicate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only one headphone jack is provided in the display, then the device complexity is reduced, but the adaptability for connecting multiple headsets is insufficient
Solution Approach 1:
The display device is equipped with multiple audio connectors (first, second, and third audio connectors) that can all receive audio signals from the host device through the mixer and amplifier circuit. This allows the display to serve multiple functions: it can connect multiple headsets simultaneously for different users, enable communication between users by transmitting audio signals between connectors, and maintain backward compatibility with single headset connections. The mixer and amplifier circuit acts as a universal interface that distributes audio signals to all connected headsets.
2Adaptability or versatility
If multiple audio connectors are added to support multiple headsets, then the adaptability for multiplayer scenarios is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple audio input/output functions into a single mixer and amplifier circuit. This circuit integrates the functionality of multiple audio jacks, allowing it to simultaneously handle audio distribution to multiple headsets and audio transmission between headsets. By merging these functions into one circuit, the patent reduces the need for separate amplifiers and signal processing components for each audio connector, thereby managing device complexity while supporting multiple headsets.
Solution Approach 2:
The mixer and amplifier circuit serves as an intermediary between the host device and multiple headsets. It receives the audio signal from the host device and distributes it to all connected headsets, or transmits audio signals between headsets for communication purposes. This intermediary approach allows the display to manage multiple audio connections through a single intelligent interface, simplifying the overall system architecture while enabling complex multiplayer audio scenarios.
