Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio devices with multiple audio interfaces are large in size and cannot be miniaturized, posing challenges for function-intensive products that require audio monitoring and time code input/output functions.
Innovation Solution
A single audio interface signal switching circuit with a single audio receptacle, an audio signal output module, a time code input module, a time code output module, and a driver chip, where a working mode switching module controls the driver chip to manage the states of these modules, reducing the overall volume by eliminating the need for multiple interfaces.

Engineering Contradiction Analysis
1Adaptability or versatility
If multiple audio interfaces are used to implement audio monitoring and time code input/output functions, then the device functionality is complete, but the device volume becomes large and cannot be miniaturized
Solution Approach 1:
The single audio interface receptacle is designed to universally support multiple functions including audio monitoring, time code input, and time code output by dynamically switching its working states through the driver chip, eliminating the need for separate dedicated interfaces for each function
Solution Approach 2:
The driver chip dynamically changes the electrical connection states of the single audio interface receptacle based on different working modes (audio output mode, time code input mode, time code output mode), allowing the same physical interface to adapt to different functional requirements through dynamic reconfiguration

AI summary
A single audio interface signal switching circuit and a single audio interface switching device are provided by the embodiments of the present disclosure, which sets only one single audio interface and uses a working mode switching module to control a driver chip to generate different drive signals, in order to control working states of an audio signal output module, a time code input module, and a time code output module electrically connected with the driver chip. Since there is only one audio interface, and a working mode of the single audio interface switching device is controlled by the working mode switching module, so that a volume of the single audio interface switching device is reduced.
