Speaker Equalization by Device Orientation for Better Audio Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack an effective method to dynamically adjust audio equalization settings based on the position or orientation of the active speaker relative to a surface, leading to suboptimal audio playback quality.
Innovation Solution
The electronic device utilizes data from various sensors, such as accelerometers, gyroscopes, and proximity sensors, to determine its local position and orientation, and then applies corresponding equalization settings to the audio data, ensuring optimal audio output regardless of the device's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If audio equalization settings are fixed regardless of device position, then device complexity is reduced, but audio playback quality deteriorates
Solution Approach 1:
The patent implements dynamic equalization settings that automatically adjust based on the device's detected position and orientation. The system transitions from static, fixed equalization to dynamic, position-dependent equalization, allowing audio playback quality to be optimized for each specific device orientation while managing complexity through automated sensor-based detection and pre-configured equalization profiles.
Solution Approach 2:
The system uses sensor feedback (accelerometers, gyroscopes, proximity sensors) to detect device position and orientation, then applies corresponding equalization settings based on this feedback. This closed-loop approach enables the system to automatically adapt audio output to the device's physical state, resolving the contradiction between maintaining simple fixed settings and achieving high variable quality.
2Manufacturing precision
If sensor data processing is implemented to determine device position, then audio playback quality is improved, but use of energy increases
Solution Approach 1:
The patent pre-configures equalization settings for various device positions and orientations before runtime. During operation, the system only needs to detect the current position and retrieve the corresponding pre-computed settings, rather than performing complex real-time audio processing. This preliminary preparation significantly reduces the energy required during actual audio playback while maintaining high audio quality.
3Manufacturing precision
If equalization settings are applied based on speaker position, then audio playback quality is improved, but device complexity increases
Solution Approach 1:
The patent leverages existing multi-functional sensors (accelerometers, gyroscopes, proximity sensors) already present in the device for other purposes, using them additionally for position detection in audio equalization. This approach avoids adding dedicated hardware and utilizes the universal capability of existing components to serve multiple functions, thereby improving audio quality without proportionally increasing device complexity.

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.
