Cymbal Pickup Sensor Mounting With Elastic Buffer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cymbal pickups face issues with unstable vibration detection due to strong fastening forces compressing the piezo element, leading to deformation and potential damage when the cymbal is hit, as the separation distance between washers is affected, hindering accurate signal output.
Innovation Solution
A cymbal pickup design with a sensor attaching part of predetermined hardness and an insertion part to maintain separation distance, along with buffer parts of varying elasticity to secure the cymbal and reduce vibration damping, ensuring the piezo sensor detects vibrations accurately without deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a strong fastening force is applied by the nut to secure the cymbal and pickup, then the cymbal and pickup are firmly secured, but the piezo element is compressed and its vibration is hindered
Solution Approach 1:
A buffer part made of elastic material is introduced as an intermediary between the first abutting part and the second abutting part. This buffer part absorbs the fastening force applied by the nut, preventing direct compression of the piezo element while still securing the cymbal and pickup firmly. The elastic material allows the buffer part to deform under fastening force and then recover, maintaining stable separation distance and enabling reliable vibration detection.
2Force
If the cymbal is strongly hit, then the vibration signal is strong, but the cymbal tilts and bends the pickup, deforming the piezo element
Solution Approach 1:
The buffer part made of elastic material provides beforehand cushioning for the piezo element against deformation caused by strong hits. When the cymbal is strongly hit and tilts, the buffer part deforms to absorb the impact force, preventing the transmission of bending forces to the piezo element. This prior cushioning protection ensures the piezo element remains undamaged and maintains accurate vibration detection capability.
3Adaptability or versatility
If the separation distance between washers is allowed to vary, then the fastening is more flexible, but the piezo element deformation occurs affecting detection accuracy
Solution Approach 1:
The buffer part's elastic properties enable it to change its physical state (deformation) in response to varying forces, maintaining a stable separation distance under different conditions. When fastening force is applied or when the cymbal is hit, the buffer part deforms to absorb these forces while maintaining consistent spacing between the abutting parts, ensuring the piezo element operates at optimal detection precision regardless of fastening flexibility requirements.

AI summary
A cymbal pickup is described, including a sensor detecting the vibration of the cymbal, and a sensor attaching part to which the sensor is attached. The cymbal has, through its center, a hole that allows a rod to be inserted through. The sensor attaching part includes: a first abutting part having a first insertion hole for pass of the rod, a second abutting part configured opposite to a side of the first abutting part and having a second insertion hole for pass of the rod, and an insertion part between the two abutting parts to maintain a separation distance between the opposite sides of the two abutting parts. The sensor is attached to a side of the first or the second abutting part. The cymbal pickup abuts the cymbal and is fixed together with the cymbal to detect its vibration while the rod is inserted through them.
