Electronic Percussion Instrument Cover Deflection Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic percussion instruments suffer from noise pollution due to sound-box reverberations, which degrade sound quality and noiselessness.
Innovation Solution
An electronic percussion instrument design featuring a pad member with an impact sensor, a cover member that externally covers the pad member without contacting it, and a fixing member that supports the cover member, allowing for non-contact operation and reduced noise through deflection of the pad-attaching portion of the stay during impact, thereby suppressing sound-box reverberations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the head is fixed to the cylindrical shell, then sound amplification is improved, but sound-box reverberations increase causing noise
Solution Approach 1:
The patent extracts the harmful connection between the head and shell by introducing a cover member that does not contact the head. The cover member is attached to the stand separately, creating a non-contact configuration that eliminates the path for sound-box reverberations while preserving the head's vibration transmission to the impact sensor and shell for useful sound generation.
2Reliability
If a cover is added to protect the head and provide exterior design, then protection and aesthetics are improved, but sound-box reverberations increase
Solution Approach 1:
The patent uses the stand as an intermediary structure to attach the cover member without direct contact with the head. The cover member is fixed to the stand rather than the head or shell, creating a mediator configuration that provides protection and aesthetic coverage while preventing the cover from becoming a source of sound-box reverberations.
3Stability of the object's composition
If the cover contacts the pad member, then structural stability is improved, but noise pollution increases
Solution Approach 1:
The patent segments the support structure into separate components: the stand, the pad member, and the cover member. The cover member is attached to the stand independently from the pad member, creating a segmented configuration that maintains structural stability through the stand while preventing noise-generating contact between the cover and pad member during vibration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces noise pollution and enhances sound quality by maintaining a non-contact condition between the cover and pad members, while also improving the durability of the instrument.
Implementation Method 1
an impact sensor which converts vibration of a head being struck with a beater into an electric signal so as to generate an electronic musical sound

AI summary
An electronic percussion instrument includes a stand, a pad member with a head, and an impact sensor, a cover member, and a support member (e.g. a stay). The support member has an L-shape including a stand-attaching portion and a pad-attaching portion which are perpendicularly unified together at an inflection point. The stand-attaching portion is attached to the stand while the pad-attaching portion is attached to the pad member. The cover member is attached to the support member such that the cover member will not brought into contact with the pad member via a clearance which is maintained irrespective of an impact applied to the head with a beater. The pad-attaching portion is backwardly deflected about the inflection point relative to the stand-attaching portion due to an impact on the head. Thus, it is possible to reduce sound-box reverberations and to secure noiselessness.
