Acoustic Device Touch Panel Parameter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing acoustic devices require continuous pressing of a planar position sensor to change parameter values, making the operation complex and cumbersome.
Innovation Solution
An acoustic device and operation method that utilize a touch panel to detect two-dimensional touch operations, allowing parameter values to be easily changed by moving a pointer within defined control ranges on a touch screen, enabling continuous parameter adjustments without continuous touch input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If parameter values are manipulated based on pressed position on a planar position sensor, then parameter values can be changed, but continuous pressing is required which complicates the operation
Solution Approach 1:
The patent applies preliminary action by setting parameter values based on the touch position itself rather than requiring continuous pressing. When the user touches a position on the touch panel, the parameter value is immediately set according to that position, and the effect is applied. This eliminates the need for continuous pressing while maintaining precise parameter control.
Solution Approach 2:
The patent implements periodic action by applying the effect parameter at specific moments (when touch is detected) rather than requiring continuous input. The system detects touch position, sets the parameter value, and applies the effect in discrete periodic updates, simplifying user interaction while maintaining control precision.
2Adaptability or versatility
If continuous pressing is required to change parameter values, then parameter control is possible, but user interaction becomes cumbersome
Solution Approach 1:
The system performs preliminary action by pre-establishing the relationship between touch position and parameter value. The parameter value is determined based on the touch position coordinates, and this mapping is prepared in advance, allowing users to simply touch the desired position without complex continuous manipulation.
Solution Approach 2:
The patent replaces the mechanical continuous pressing system with a digital touch position detection system. Instead of requiring continuous mechanical pressure to maintain parameter changes, the system uses digital coordinates from the touch panel to directly set parameter values, substituting mechanical continuity with digital precision.

AI summary
An acoustic device (10) includes a touch panel (51) for detecting a user's touch operation, a value setting section (569) for setting a parameter value based on the touch operation detected by the touch panel, and an output control section (43) for processing an inputted audio based on the parameter value set by the value setting section (569) and outputting the processed audio. The value setting section (569) sets the parameter value in accordance with a moving direction and a moving speed of a touch position from a start point (SP) that is the touch position on the touch panel (51) at a start of the touch operation to an end point (EP) that is the touch position at an end of the touch operation.
