Touchscreen Digital Instrument Sound Source Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital musical instruments are limited in reproducing multiple sound sources simultaneously or sequentially in response to a single keyboard input, only producing a single stored sound source.
Innovation Solution
An electronic device with a touchscreen displaying a keyboard and sound source buttons, a processor, and memory that stores instructions to reproduce the selected sound source corresponding to the input, allowing for simultaneous or sequential output of multiple sound sources based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a digital musical instrument reproduces only a single stored sound source in response to keyboard input, then the device complexity is low, but the adaptability and versatility are limited
Solution Approach 1:
The patent implements multi-functionality by enabling a single digital musical instrument to reproduce multiple different sound sources (e.g., piano, violin, flute) in response to keyboard input. The system allows users to select from various stored sound sources and reproduce them simultaneously or sequentially, making one device capable of performing multiple musical instrument functions without requiring separate physical instruments for each sound type.
2Adaptability or versatility
If a digital musical instrument reproduces multiple sound sources simultaneously or sequentially, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-storing multiple sound sources in the device's memory before use. The system prepares various musical instrument sounds (piano, violin, flute, etc.) in advance and stores them for quick retrieval. When a user inputs a keyboard signal, the system can immediately reproduce the selected sound source without requiring real-time synthesis or external resources, thus managing complexity through advance preparation.
3Adaptability or versatility
If a digital musical instrument stores and reproduces multiple sound sources, then the versatility improves, but the memory requirements and data storage needs increase
Solution Approach 1:
The patent implements copying by storing digital representations of musical instrument sounds in memory. Instead of requiring physical copies of instruments or complex real-time synthesis, the system creates digital copies of sound waveforms from various instruments and stores these for reproduction. This allows multiple sound sources to be stored efficiently in digital form, reducing the physical space and resource requirements while maintaining versatility.
Data Source
AI summary
An electronic device and a method for reproducing a sound in the electronic device are provided. The electronic device includes a touchscreen displaying a keyboard having a plurality of keys and a plurality of sound source buttons corresponding respectively to a plurality of different sound sources, a processor connected electrically to the touchscreen, and a memory connected electrically to the processor, wherein the memory stores instructions that are executed to cause the processor to perform control such that when an input to at least one key among the plurality of keys is received, the sound source corresponding to at least one sound source button selected among the plurality of sound source buttons is reproduced as a sound corresponding to the received input.
