Dynamic Audio Output Control for Orientation-Based Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic audio reproduction devices output audio signals in a fixed direction, requiring users to adjust their listening position or the device's position to optimize audio playback, leading to inefficient and user-unfriendly experiences.
Innovation Solution
An electronic device with a processing portion and multiple audio output portions that can vary and control audio characteristics based on image, optical, voice input signals, movement, and orientation changes, allowing for dynamic adjustment of audio output directionality, channel output, frequency range impedance, and 3D audio positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If speaker drivers are fixed in a specific direction, then the device structure is simple, but the user must manually adjust listening position or device position to optimize audio playback
Solution Approach 1:
The patent applies dynamics by making the audio output portions movable rather than fixed. The speaker drivers can change their orientation and positioning dynamically in response to device orientation changes, allowing the audio output direction to adapt automatically without manual user adjustment, thus resolving the contradiction between ease of operation and device complexity
Solution Approach 2:
The patent implements feedback mechanisms where sensors detect device orientation and movement, and this information is fed back to the processing portion which then adjusts the audio output portions accordingly. This closed-loop feedback system enables automatic optimization of audio playback direction based on real-time device state, eliminating the need for manual user adjustment while maintaining manageable device complexity through systematic control
2Adaptability or versatility
If the device automatically adjusts audio output based on orientation and movement, then user experience is improved, but the device complexity increases
Solution Approach 1:
The patent segments the audio output system into multiple independent audio output portions (speaker drivers) that can be individually controlled. This segmentation allows the processing portion to selectively adjust the orientation and activation of specific speaker drivers based on device orientation and movement, enabling sophisticated adaptive audio playback while managing overall system complexity through modular control of individual segments
Solution Approach 2:
The processing portion is designed with multi-functionality, handling not only audio signal processing but also sensor data interpretation and real-time control of audio output portions. This universal control unit consolidates multiple functions into a single component, enhancing audio playback adaptability while preventing excessive device complexity by avoiding redundant dedicated components for each function

AI summary
An electronic device is provided. The electronic device can include a processing portion and one or more audio output portions. Based on any of, or any combination of, the image signals, optical signals, voice input signals, movement of the electronic device and change in orientation of the electronic device, the processing portion can be configured to do one or both of varying/controlling at least a portion of the audio characteristics of the audio input signals and varying/controlling output of audio output signals.
