Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing music lighting technologies for digital keyboard instruments only allow rough control of light-emitting effects associated with a fixed pitch, failing to achieve subtle control through key actions.
Innovation Solution
A method and apparatus that utilize sensors underneath each key of a digital keyboard musical instrument to detect touch actions, generating touch signals with magnitude information, which are then processed to produce corresponding control signals for precise light-emitting effects, including changes in color, brightness, or flashing frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing music lighting technology converts sound signals into control signals for light-emitting, then light-emitting effects can be associated with fixed pitch, but the control precision and subtlety of light-emitting effects deteriorates
Solution Approach 1:
The patent divides the key detection function into multiple segments: a sensor array underneath each key to detect touch actions, a processor to analyze touch magnitude and duration, and separate light-emitting control modules. This segmentation allows precise measurement of touch parameters while maintaining manageable system complexity through modular design.
Solution Approach 2:
The patent introduces an intermediary sensor system between the key and the light-emitting control. The sensor detects touch actions and converts them into electrical signals, which then pass through the processor for analysis before controlling the light-emitting device. This intermediary layer enables precise measurement of touch magnitude without directly complicating the light control mechanism.
2Measurement precision
If sensors are placed underneath each key to detect touch actions with magnitude information, then light-emitting control precision is improved, but device complexity increases
Solution Approach 1:
The sensor system underneath each key serves multiple functions: detecting key press events, measuring touch magnitude, and providing data for light-emitting control. This multi-functionality reduces the need for separate specialized components, thereby improving detection precision while limiting the increase in overall device complexity.
Solution Approach 2:
The sensor system is integrated directly into the key mechanism, allowing the key structure itself to serve as part of the detection system. The processor automatically analyzes touch magnitude and duration without requiring external intervention, enabling the system to self-regulate and control light-emitting effects based on detected actions.

AI summary
The present invention provides a method and apparatus for controlling a light-emitting device of a digital keyboard musical instrument. The method includes: detecting a touch action generated by a user upon a key of the digital keyboard musical instrument and generating a touch signal, by a sensor placed underneath the key, and transmitting the touch signal to a processor, wherein the touch signal comprises the magnitude information of the touch action; receiving the touch signal and generating a corresponding control signal in accordance with the magnitude information of the touch signal, by the processor; and actuating the light-emitting device to produce a light-emitting effect in accordance with the control signal by the processor. Since the detection of the touch action upon the key by the sensors is accurate enough to capture all details of the complete key-touching action, the light-emitting effect produced based on this more detailed detection of the touch action is more exquisite and accurate.
