Variable Volume Modes for Fast and Precise Audio Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices struggle to allow users to quickly and accurately adjust volume levels due to fixed volume intervals, either resulting in rapid but imprecise changes or slow and fine adjustments, failing to accommodate varying user circumstances effectively.
Innovation Solution
Implementing a method and apparatus that allow users to set multiple volume modes with different interval values, enabling the selection of a volume mode based on specific circumstances, such as noise levels or environments, to adjust volume levels accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the volume control interval is set to be large, then it is possible to immediately adjust the volume from the minimum volume level to the maximum volume level or from the maximum volume level to the minimum volume level, but it is difficult to finely adjust the volume
Solution Approach 1:
The patent applies dynamics by making the volume control interval variable rather than fixed. The system dynamically adjusts the interval size based on the current volume level and user operations. When the volume is at extreme levels (minimum or maximum), the system uses larger intervals for rapid adjustment. When the volume is at intermediate levels, the system switches to smaller intervals for fine-tuned control. This dynamic adaptation resolves the contradiction between fast adjustment and fine control precision.
2Measurement precision
If the volume control interval is set to be small, then it is possible to finely adjust the volume, but it takes much time in adjusting the volume from the minimum volume level to the maximum volume level or from the maximum volume level to the minimum volume level
Solution Approach 1:
The system dynamically changes the control interval based on operational context. During initial volume adjustments from extremes, larger intervals are used to minimize adjustment time. As the volume approaches intermediate levels or when fine-tuning is detected, the system automatically switches to smaller intervals for precise control. This dynamic adaptation eliminates the need to choose between speed and precision, as both are optimized at different stages of the adjustment process.
3Productivity
If the volume difference between the volume levels is set to be greater than 1 level, then it is possible to rapidly change the volume between the volume levels, but it is difficult to finely control the volume
Solution Approach 1:
The patent segments the volume control process into different phases with different interval characteristics. The first phase uses larger volume differences for rapid coarse adjustment when productivity is prioritized. The second phase uses smaller volume differences for fine control when precision is prioritized. This segmentation allows the system to optimize for different objectives at different times, resolving the contradiction between efficiency and precision in volume control.

AI summary
A method and an apparatus for controlling/adjusting volume, which can set multiple volume modes having different volume intervals and control volume by a volume interval of a corresponding volume mode according to a given circumstance in an electronic device having a volume change function. The method includes detecting a volume change event; when the volume change event is a volume mode change, changing a current volume mode to a volume mode corresponding to the volume change event; and when the volume change event is a volume value change, controlling volume up/down in response to the volume change event.
