Hi-hat Cymbal Sound Generation Preventing Unintended Tone Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic hi-hat cymbal systems fail to accurately replicate the sound dynamics of real hi-hat cymbals, particularly when hit hard in non-close states, leading to sounds that are either muted unintentionally or differ significantly from the real cymbals.
Innovation Solution
A hi-hat cymbal sound generation apparatus that acquires distance and vibration information between a top and bottom pad, adjusts state information based on corrected distance, and controls sound generation and volume to mimic the sound dynamics of real hi-hat cymbals by starting sound generation procedures and adjusting volume according to the intensity of vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the top cymbal is hit hard with a stick in a non-close state, then the generated sound should be closer to the open state sound, but the existing system causes the tone to stop unintentionally or generates sound different from real hi-hat cymbals
Solution Approach 1:
The system dynamically adjusts the state determination based on vibration intensity. When hard hitting is detected through vibration information, the system temporarily modifies the state transition logic to prevent unintended tone stopping, allowing the sound to continue naturally as in real hi-hat cymbals while maintaining accurate state-based sound selection
Solution Approach 2:
The system uses vibration information as feedback to detect hard hitting conditions and adjusts the tone stop instruction timing accordingly. By measuring vibration magnitude and duration, the system determines whether to suppress automatic tone stopping, thereby preventing the harmful effect of unintended silence while maintaining reliable sound generation
2Measurement precision
If the distance between top pad and bottom pad is used to determine state information, then the state can be accurately identified, but the vibration caused by hard hitting shifts the sound toward open state instead of maintaining the actual state
Solution Approach 1:
The system performs preliminary vibration analysis before finalizing state determination. By detecting vibration intensity in advance of state transition, the system can anticipate hard hitting conditions and adjust state information accordingly, preventing the sound from incorrectly shifting to open state while maintaining precise distance-based state identification for normal playing conditions

AI summary
A hi-hat cymbal sound generation apparatus according to the present invention includes an input part, a recording part, a trigger part and a sound volume control part. The input part acquires distance information on a distance between a top pad and a bottom pad, state information and vibration information on a vibration of the top pad. The input part acquires the state information by determining the state information based on a corrected distance, which is obtained by adding a distance correction value, which corresponds to a magnitude of the vibration indicated by the vibration information, to the distance indicated by the distance information. The recording part records data on a hit sound in each state indicated by the state information. The trigger part checks whether the vibration indicated by the vibration information falls within a predetermined range in which a sound generation procedure is to be started.
