Voice Remote Audio-Distance Control for Battery-Saving Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote controllers with voice recognition functions consume battery quickly due to continuous ambient sound reception, leading to rapid battery drain.
Innovation Solution
An electronic device that determines the accuracy of voice reception based on audio output level and spacing distance, controlling microphone activation and voice transmission to minimize battery drain by transmitting voice reception notifications between devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the remote controller continuously receives ambient sound to enable voice recognition function, then voice reception capability is improved, but battery consumption increases rapidly
Solution Approach 1:
The patent applies dynamics by making the voice reception state changeable between active and inactive based on environmental conditions. The processor dynamically adjusts the microphone's operational state according to the detected audio output level from the first electronic device, allowing the system to adapt its voice reception capability to current usage scenarios rather than maintaining a fixed continuous reception mode.
Solution Approach 2:
The patent changes the operational parameters of the microphone based on the audio output level detected from the first electronic device. When the audio output level exceeds a predetermined threshold, the system transitions the microphone to an inactive state, effectively changing its operational parameter from active listening to power-saving mode, thus reducing battery consumption while maintaining voice recognition capability when needed.
2Measurement precision
If the microphone is activated continuously for voice recognition, then voice accuracy is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic action by alternating between active voice reception periods and inactive power-saving periods. The processor periodically evaluates the audio output level from the first electronic device and adjusts the microphone's operational state accordingly, creating a rhythm of active listening when audio levels are low and power-saving mode when audio levels are high, thus balancing voice accuracy with energy conservation.
3Speed
If the voice reception function is always active, then response time to user commands is improved, but battery life decreases
Solution Approach 1:
The patent applies preliminary action by proactively detecting the audio output level from the first electronic device before the user attempts to use voice recognition. The processor evaluates environmental audio conditions in advance and pre-adjusts the microphone's operational state, ensuring that when the user issues a voice command, the system is already optimized for either active reception or power-saving mode, thus maintaining quick response when appropriate while extending battery life.

AI summary
A first electronic device includes an audio outputter; a communicator configured to transmit data to and receive data from a second electronic device; a memory storing one or more instructions; and at least one processor configured to execute the one or more instructions to: obtain an audio output level of an audio that is output through the audio outputter; obtain a spacing distance between the second electronic device and the first electronic device; based on the obtained audio output level and the obtained spacing distance, obtain a voice reception notification indicating whether a voice can be accurately received by the second electronic device, and control the communicator to transmit the obtained voice reception notification to the second electronic device.
