Engineering Contradiction Analysis
1Ease of operation
If manual volume adjustment is implemented, then the device structure remains simple, but the ease of operation deteriorates due to inconvenient user actions in varying noise environments
Solution Approach 1:
The system enables self-service by allowing the smart glasses to automatically detect ambient noise levels and adjust output volume without user intervention. The processor continuously monitors audio signals from microphones, determines noise levels, and autonomously controls speaker output according to preset corresponding relationships, making the device serve itself rather than requiring manual user adjustment.
Solution Approach 2:
The system implements feedback control by continuously monitoring ambient noise through microphones, processing the audio signals to determine noise levels, and adjusting speaker output accordingly. This closed-loop feedback mechanism ensures the output volume dynamically adapts to changing environmental conditions, maintaining optimal audio experience without manual intervention.
2Extent of automation
If automatic volume control is implemented, then the ease of operation improves, but the device complexity worsens due to additional processing requirements
Solution Approach 1:
The processor within the wireless communication module performs multiple functions: it handles wireless communication protocols, processes audio signals from microphones, determines noise levels, and controls speaker output. By making the processor multi-functional, the system achieves automatic volume control without adding separate dedicated hardware components, thus minimizing the increase in device complexity while maximizing automation.
Solution Approach 2:
The system merges the volume control functionality with the existing wireless communication module and processor. Instead of creating a separate automatic volume control system, the patent integrates noise detection and volume adjustment functions into the existing processor architecture, combining multiple functions into a unified control system that reduces overall device complexity.

AI summary
Smart glasses, method and device for automatic volume control, and smart glasses system are provided. The smart glasses include: a glasses body, and a wireless communication module, microphone(s) and speaker(s) provided on the glasses body. The wireless communication module has a processor connected to the microphone(s) and the speaker(s). The microphone(s) transmit a picked up audio signal to the processor. The processor determines whether the audio signal is a noise signal, calculates a noise level of the noise signal when the audio signal is the noise signal, and adjusts an output volume of the speaker(s) to an output volume corresponding to the noise level of the noise signal according to a preset corresponding relationship between noise levels and output volumes of the speaker(s).
