Synchronized Audio Vibration Feedback for Immersive Media
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices fail to provide immersive experiences for movies or games without the need for expensive and inconvenient special motion chairs, which are typically required for effective immersion through vibration or movement.
Innovation Solution
An electronic device comprising a host and an earphone that uses intelligent feedback control modules to generate and mix audio and vibration signals, allowing for synchronized audio and vibration feedback to enhance immersion, utilizing databases to match audio and vibration characteristics for optimal feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a special motion chair is used to provide vibration or movement for immersement, then the immersement experience is improved, but the cost and portability are worsened
Solution Approach 1:
The patent replaces the mechanical motion chair system with an electronic system consisting of audio output devices and vibration motors integrated into portable electronics. Instead of using a separate mechanical chair to provide immersion, the invention integrates vibration actuators and audio output into a compact device that can be held or worn by the user, thereby eliminating the need for expensive and non-portable motion chairs while maintaining the immersion effect through synchronized audio and vibration feedback
Solution Approach 2:
The patent combines multiple functions (audio output, vibration generation, and control processing) into a single integrated portable device. By merging the audio player, vibration motors, and control module into one unit, the invention eliminates the need for separate motion chair equipment while providing synchronized multi-sensory feedback for immersion in movies or games
2Reliability
If synchronized audio and vibration signals are generated, then the immersement effect is improved, but the device complexity is increased
Solution Approach 1:
The patent implements a feedback control system where a sensor detects the actual vibration output and feeds this information back to a controller, which then adjusts the vibration motor actuation to match the desired vibration profile. This closed-loop feedback mechanism enables precise synchronization between audio and vibration signals while using simple, low-cost components rather than complex signal generation hardware
Solution Approach 2:
The system uses the device's own sensor output to automatically control and synchronize the vibration motor actuation. The sensor detects vibration characteristics and the controller automatically adjusts the motor input based on this self-measured data, eliminating the need for external complex control systems or manual synchronization

AI summary
An electronic device includes a host and an earphone. The host includes a application module, the earphone includes at least one speaker, and at least one vibrator. The host generates a first vibration signal according to an original audio signal from the application module, and sends the original audio signal and the first vibration signal to the earphone. The earphone generates a second vibration signal according to the original audio signal, sends the first vibration signal and the second vibration signal to the at least one vibrator, and sends the original audio signal to the at least one earphone speaker. The electronic device may also generate audio signals according to an original vibration signal from the application module.
