Mesh Drumhead Assembly with Incompressible Ring for Sound Fidelity

Solution Overview

Problem

Conventional silent drumheads lack fidelity in sound production, have a different striking feel from conventional drumheads, and suffer from poor structural strength and durability.

Innovation Solution

A drumhead assembly comprising a mesh material drumhead with an incompressible plastic ring member on the opposite side, providing a realistic drumming feel and improved structural strength through a thin plastic ring with specific radius and thickness differences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a soft mesh material is used for the silent drumhead, then the sound level is reduced, but the sound fidelity deteriorates and the striking feel becomes different from conventional drumheads

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent uses a composite structure combining a mesh material drumhead with an incompressible plastic material ring member. The mesh material (such as polyester) provides sound absorption and reduced sound level, while the incompressible plastic ring member restores structural strength and improves striking feel. This composite approach allows the drumhead to achieve both noise reduction and maintained sound fidelity by combining materials with complementary properties.

Solution Approach 2:

The patent applies local quality by placing the incompressible plastic ring member at specific locations (around the periphery and/or at the center of the drumhead). This localized reinforcement provides structural strength exactly where needed to support the mesh material, while allowing the mesh material to maintain its sound-absorbing properties in other areas. The ring member's strategic placement optimizes both structural support and acoustic performance.

AI summary

A drumhead assembly is provided, including: a drumhead and a ring member. The drumhead is made of a mesh material and has a striking surface. The ring member is disposed on a side of the drumhead opposite to the striking surface, and the ring member is made of an incompressible plastic material. Therefore, the drumhead assembly of the present invention provides realistic drumming feel and sound performance close to those of a conventional drumhead, which overcomes the problems of poor drumming feel, distortion in timbre and pitch performances, and poor structural strength of a conventional silent drumhead.
