Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio playback methods on mobile devices are monotonous and inflexible, lacking the ability to provide tactile feedback through vibrations.
Innovation Solution
A method and system that acquires a vibration file corresponding to an audio, which includes vibration intensity and frequency, and synchronously plays the audio and vibration file, controlling the terminal's vibration motor to enhance the playback experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If audio is played only through built-in speaker or externally connected earphone, then the audio playback function is simple and reliable, but the versatility and flexibility of presenting audios is poor
Solution Approach 1:
The patent applies multi-functionality by enabling the terminal to present audio through multiple channels: traditional audio output (speaker/earphone) and tactile feedback (vibration motor). The vibration motor is controlled to vibrate according to vibration intensity and frequency parameters extracted from the audio, allowing the same device to serve both auditory and tactile presentation functions, thereby improving versatility without requiring separate dedicated devices
Solution Approach 2:
The patent implements dynamics by making the vibration motor's operation adjustable and controllable based on audio characteristics. The vibration intensity and frequency are dynamically modified according to extracted audio features, allowing the tactile feedback to adapt to different audio content and presentation scenarios, thus enhancing flexibility in how audio is presented to the user
2Adaptability or versatility
If vibration motor is added to provide tactile feedback, then the user experience is enriched, but the device complexity increases
Solution Approach 1:
The vibration motor, which is a common component in mobile terminals, is repurposed to serve dual functions: traditional notification/vibration functions and audio tactile feedback presentation. By controlling the vibration motor according to audio-derived parameters (intensity and frequency), the patent enables one existing component to fulfill multiple roles, enriching user experience without requiring entirely new dedicated hardware
Solution Approach 2:
The system automatically extracts vibration intensity and frequency parameters from the audio content itself, then uses these extracted parameters to control the vibration motor. This self-service approach means the system adapts to different audio content autonomously without requiring manual user configuration or complex external control systems, thereby enriching experience while minimizing added complexity

AI summary
Provided a method for playing audios. The method includes: acquiring vibration control information corresponding to a target audio, wherein at least one vibration period and vibration attribute information corresponding to the at least one vibration period are recorded in the vibration control information, and each vibration period corresponds to a beat period of a target percussive instrument in the target audio; synchronously playing the target audio and the vibration control information; and when any vibration period of the at least one vibration period is played, controlling a terminal to vibrate based on vibration attribute information corresponding to the vibration period.
