Drumstick Mallet Head with Cavity Indentations for Sound Customization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drumsticks for percussion instruments often have unchangeable sound characteristics due to permanently connected celluloid or rubber caps, which can lead to excessive wear on batter skins and lack versatility for practicing on non-resonant surfaces.
Innovation Solution
A drumstick design featuring a mallet head with a blind hole and inner lateral surface indentations, allowing for varying sound behavior through structural design and filling materials like adhesives or air in cavities, and made from elastic polymer materials for improved durability and playability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a celluloid cover or rubber cap is permanently connected to the drumstick shaft, then the drumstick head is stabilized and provides specific sound characteristics, but the sound characteristics become unchangeable and the drumstick wears down batter skins excessively
Solution Approach 1:
The drumstick head is divided into multiple segments or layers with different materials (e.g., hard outer layer for durability, softer inner layers for sound variation). This segmentation allows different portions of the head to provide different sound characteristics while maintaining overall structural stability, resolving the contradiction between reliability and adaptability.
Solution Approach 2:
Different regions of the drumstick head are made from materials with different properties (e.g., harder material at the tip for durability, softer material in the body for sound variation). This local differentiation allows the drumstick to provide both stable structural performance and variable sound characteristics depending on which part contacts the batter skin.
2Ease of operation
If a hard and non-resonant surface is used for practicing, then the musician can practice without the actual instrument, but the drumstick cannot simulate realistic sound behavior on resonant surfaces
Solution Approach 1:
The drumstick head uses composite materials combining hard and resonant properties (e.g., wood core with resonant characteristics covered by a protective layer). This composite structure allows the drumstick to simulate realistic sound behavior when practicing on both resonant and non-resonant surfaces, maintaining reliability across different practice conditions while enabling ease of operation.
3Adaptability or versatility
If indentations are provided on the inner lateral surface of the blind hole, then customizable sound behavior is achieved through cavity filling, but the manufacturing complexity increases
Solution Approach 1:
The blind hole with indentations is pre-formed during the drumstick head manufacturing process using mold cavities or machining operations. This preliminary action integrates the complex geometric features into the base manufacturing step, allowing subsequent cavity filling for sound customization without requiring additional complex assembly operations, thus managing manufacturing complexity while enabling adaptability.

AI summary
The invention relates to a drumstick for a percussion instrument, comprising a substantially elongated stick shaft, on which a connection part is formed at at least one shaft end, on which a stick head (10) produced from a polymer material is arranged on one side at the end in a surrounding manner and is connected to same, wherein, in order to enlarge the inner casing surface of the stick head (10) one or more substantially concentrically arranged depressions (105) are formed on the inner casing surface, such that one or more hollow spaces occur, wherein the acoustic pattern when playing the percussion instrument depends on the containment of air and/or adhesive in the one hollow space or multiple hollow spaces.
