Keyboard Musical Instrument Character Input Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic keyboard musical instruments lack operability when users attempt to input character information such as lyrics or song titles, as they are not designed to accept such inputs effectively.
Innovation Solution
A keyboard musical instrument with a processor that allows for both musical sound production and symbol input modes, where white and black keys are assigned characters, enabling users to input characters by combining key presses on the keyboard.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic keyboard musical instrument is designed only for musical sound production, then the device complexity is reduced and manufacturing is easier, but the ease of operation deteriorates when users need to input character information
Solution Approach 1:
The keyboard is designed to perform multiple functions: it can produce musical sounds in musical sound producing mode and accept character information input in symbol input mode. Each white key is allocated with multiple characters, allowing the same physical key to serve both musical and character input purposes, thereby improving ease of operation without adding separate input devices
Solution Approach 2:
The keyboard's functionality is made dynamic through mode switching. The processor can switch between musical sound producing mode and symbol input mode, allowing the keyboard to adapt its function based on user needs. This dynamic reconfiguration enables character input capability without requiring permanent additional hardware
2Adaptability or versatility
If character input capability is added to the electronic keyboard musical instrument, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The keyboard serves as a universal input device for both musical notes and character information. By allocating multiple characters to each white key and using black keys for additional character selection, the system achieves high adaptability without adding separate keyboards or input devices, thus avoiding increased device complexity
Solution Approach 2:
The character input function is merged with the existing keyboard structure. Instead of adding a separate character keyboard, the invention combines character input capability with the musical keyboard by allocating characters to keys and using mode switching, thereby achieving versatility without increasing physical device complexity
3Ease of operation
If multiple characters are allocated to each white key for character input, then the ease of operation improves, but the manufacturing precision requirements increase
Solution Approach 1:
Each white key is allocated with multiple characters (e.g., four characters per white key), allowing users to input various characters using the same physical key. This multi-functionality improves ease of operation without requiring additional keys or complex mechanical structures, thus avoiding increased manufacturing precision requirements
Solution Approach 2:
The invention adds a conceptual dimension to the keyboard by associating multiple characters with each key. Instead of adding physical dimensions (more keys), it utilizes the informational dimension by allocating multiple character values to each physical key, thereby improving functionality without affecting manufacturing precision

AI summary
A keyboard musical instrument, a method, and a non-transitory computer-readable recording medium that improve operability are provided. An electronic musical instrument comprises a keyboard including plural white keys each of which is allocated with plural characters and plural black keys, and a controller. The controller executes, in a musical sound producing mode that is set, accepting a sound producing instruction of a musical sound in response to an operation of the keyboard, and, in a symbol input mode that is set, according to both a white key designated from the plural white keys and a black key designated from the plural black keys, accepting an input of a character among the plural characters allocated to the white key designated from the plural white keys.
