Stereo Speaker Equalization Using Orientation-Aware Sensor Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices fail to optimize audio playback based on the position and orientation of the active speaker relative to a surface, leading to suboptimal audio quality due to inadequate consideration of environmental and listener positioning.
Innovation Solution
The electronic device utilizes sensors such as accelerometers, gyroscopes, and imaging sensors to determine its position and orientation, and applies corresponding equalization settings to the audio data, adjusting frequency and phase responses to enhance audio output quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device uses fixed audio processing settings, then the device complexity is reduced, but the audio quality deteriorates when the speaker position or orientation changes
Solution Approach 1:
The audio processing system transitions from fixed settings to dynamic adaptation by using sensor data (accelerometer, gyroscope, proximity sensor) to detect device position and orientation changes, then automatically adjusting equalization settings in real-time to maintain optimal audio quality across different usage scenarios
Solution Approach 2:
The system implements feedback by continuously monitoring device orientation and position through sensors, comparing the current state against optimal playback conditions, and adjusting audio parameters accordingly to compensate for suboptimal positioning and maintain consistent audio quality
2Reliability
If the electronic device applies equalization settings based on speaker position and orientation, then the audio quality is improved, but the ease of operation deteriorates due to automatic adjustments
Solution Approach 1:
The audio processing system performs self-adjustment by automatically detecting device position and orientation through built-in sensors and applying appropriate equalization settings without requiring user intervention, making the system adapt to different usage scenarios autonomously
3Measurement precision
If the electronic device uses multiple sensors to determine position and orientation, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The system merges data from multiple sensors (accelerometer, gyroscope, proximity sensor) to comprehensively determine device position and orientation, using sensor fusion to achieve accurate spatial awareness while leveraging existing hardware components already present in modern electronic devices

AI summary
Embodiments are provided for receiving a request to output audio at a first speaker and a second speaker of an electronic device, determining that the electronic device is oriented in a portrait orientation or a landscape orientation, identifying, based on the determined orientation, a first equalization setting for the first speaker and a second equalization setting for the second speaker, providing, for output at the first speaker, a first audio signal with the first equalization setting, and providing, for output at the second speaker, a second audio signal with the second equalization setting.
