Electronic Acoustic Apparatus Control Operator Style Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic musical instruments require users to interrupt their performance operation to switch between control functions, necessitating a separate function switching switch, which complicates the user interface and disrupts the adjustment of acoustic effect parameters.
Innovation Solution
An electronic acoustic apparatus with a control operator that allows users to switch between normal and particular operation styles, enabling the execution of different functions without interrupting the adjustment of acoustic effect parameters, by detecting operating speed or acceleration to determine the operation style and issue instructions accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate function switching switch is provided to enable switching between performance operation function and screen operation function, then the user can execute different functions, but the device complexity increases and the user interface becomes more complicated
Solution Approach 1:
The control operator is designed to perform multiple functions: it can adjust acoustic effect parameters through normal operation and execute screen operations through particular operation styles (such as quick flicking motions). This multi-functional design eliminates the need for separate function switching switches while maintaining the ability to perform both performance operations and screen operations.
Solution Approach 2:
The system distinguishes between different operation styles by detecting parameters such as operating speed or acceleration. When the control operator is manipulated with specific parameter thresholds (e.g., quick flicking motion exceeding a speed threshold), the system interprets this as a command to execute screen operations rather than adjust acoustic parameters, thereby enabling function switching without additional hardware.
2Adaptability or versatility
If a function switching switch is used to switch between performance operation function and screen operation function, then different functions can be executed, but the adjustment of acoustic effect parameters is interrupted
Solution Approach 1:
The system enables continuous adjustment of acoustic effect parameters even when screen operations are needed. By detecting quick flicking motions of the control operator, the system can temporarily switch to execute screen operations and then automatically return to the parameter adjustment state, maintaining the continuity of the useful action without requiring the user to restart the adjustment process.
3Adaptability or versatility
If multiple switches are provided for different functions, then each function can be controlled independently, but the ease of operation decreases due to more operations required
Solution Approach 1:
The control operator serves as a universal control element that can perform both acoustic parameter adjustment and screen operations. By detecting the operation style (normal vs. quick flicking), the system determines the intended function, allowing users to execute different functions with a single control element rather than multiple switches, significantly improving ease of operation.

AI summary
An electronic acoustic apparatus includes a control operator, a storage medium, and a processor. The control operator is operable by a user. The storage medium stores a program. The processor is configured to adjust a predetermined control parameter of an audio signal in response to an operation of the control operator. The processor is also configured to determine that the control operator has been operated in a particular operation style different from a normal operation style that adjusts the predetermined control parameter. In response to the operation of the control operator in the particular operation style, the processor is also configured to issue an instruction to execute a predetermined function different from an adjustment of the predetermined control parameter.
