Sound Preview Device for Instant Tone Setting Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic musical instruments without operation panels lack a means to instantly confirm changes in tone selection or sound settings, requiring actual play to verify changes.
Innovation Solution
A sound preview device with a changed state recognizing unit, phrase storing unit, and sound emitting unit that emits specific sound phrases when tone selection or sound settings are changed, allowing aural confirmation of changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an electronic musical instrument is designed without an operation panel to reduce cost and simplify structure, then manufacturing cost and device complexity are reduced, but the ability to instantly confirm tone selection or sound setting changes is lost
Solution Approach 1:
The patent introduces a speaker as an intermediary device that converts setting change information into audible sound signals. Instead of using a display panel to visually present setting changes, the system uses the speaker to play back sample sounds that represent the current tone or sound setting, allowing users to aurally confirm changes without visual displays
Solution Approach 2:
The patent replaces the visual display mechanism (operation panel with LCD) with an acoustic feedback mechanism (speaker playing sample sounds). This substitution eliminates the need for complex display hardware while providing effective setting change confirmation through sound, aligning with the goal of reducing manufacturing cost and device complexity
2Device complexity
If tone selection or sound setting changes are implemented without visual display, then device complexity is reduced, but the speed of confirming changes decreases
Solution Approach 1:
The speaker acts as an intermediary that immediately converts setting change data into audible sample sounds, providing instant feedback to users. This acoustic intermediary enables real-time confirmation of tone or sound setting changes without the delay associated with visual display updates or manual key testing
Solution Approach 2:
The system automatically plays sample sounds corresponding to the current setting when changes occur, without requiring user intervention to trigger the feedback. The electronic musical instrument itself provides the confirmation service by autonomously generating and outputting the appropriate sample sound through the speaker
3Productivity
If sample sounds are played through the speaker when settings change, then confirmation speed is improved, but energy consumption increases
Solution Approach 1:
The speaker is activated periodically only when setting changes occur, rather than operating continuously. The system plays sample sounds on-demand at specific moments (when tone or sound settings are changed), allowing the speaker to remain inactive during normal operation and thereby reducing overall energy consumption while maintaining fast confirmation capability when needed

AI summary
Provided is a sound preview device including, in an electronic musical instrument which includes a keyboard 2 and an operation button 1 to perform tone selection or a sound setting and in which tone selection or a sound setting corresponding to a key is performed in advance by pressing the operation button 1 while pressing one of the keys in the keyboard 2, a changed state recognizing unit 3 that recognizes from a pressed key a changed state of tone selection or a sound setting determined corresponding to the key in advance, a phrase storing unit 4 in which phrases of sounds by which an influence of the changed state is easily known are stored in plural numbers according to the changed state, and a sound emitting unit 5 that emits a phrase corresponding to the changed state.
