The present invention relates to a drumhead assembly.
Generally, drumheads of a drum kit are made of polyester film or PET material. Recently, a silent drumhead has been developed to reduce the sound level when being struct, which is convenient for a user to practice at home or in a small space. However, the conventional silent drumhead is made of a soft mesh material so that the sound produced by the conventional silent drumhead lacks fidelity, and the feel of striking the silent drumhead is also different from that of the conventional drumhead. In addition, the conventional silent drumhead has poor structural strength, which provides poor durability.
The present invention is, therefore, arisen to obviate or at least mitigate the above-mentioned disadvantages.
The main object of the present invention is to provide a drumhead assembly, which can effectively reduce the sound level when being struck and provide a realistic drumming feel and good timbre performance.
To achieve the above and other objects, the present invention provides a drumhead assembly, 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.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.
Please refer to
The drumhead 10 is made of a mesh material and has a striking surface 11. The ring member 20 is disposed on a side of the drumhead 10 opposite to the striking surface 11, and the ring member 20 is made of an incompressible plastic material. With the ring member 20, the drumhead 10 provides a drumming feel close to a conventional drumhead (such as a drumhead made of PET), and provides a lower sound level and good timbre or pitch performance when being struck.
Specifically, the incompressible plastic material includes polyethylene terephthalate (PET), and the ring member 20 is a thin sheet. The ring member 20 includes an inner annular edge 21 and an outer annular edge 22 which are concentric with each other, and a difference of a radius of the inner annular edge 21 and a radius of the outer annular edge 22 is larger than or equal to 2 cm and smaller than or equal to 5 cm so as to effectively increase the structural strength of the drumhead assembly 1 and provide a different resonance effect compare to a conventional silent drumhead. Therefore, the drumhead assembly 1 provides concentrated sounds and good pitch performance. Preferably, the difference of the radius of the inner annular edge 21 and the radius of the outer annular edge 22 is between ⅙ and 1/9 of a radius of the drumhead 10. For example, if a size of the drumhead 10 is 14 inches, the difference of the radius of the inner annular edge 21 and the radius of the outer annular edge 22 may be 3 cm, which can reduce the sound level of the drumhead 10 and provide good drumming feel and sound performance when the drumhead 10 is struck.
A thickness of the drumhead 10 is larger than a thickness of the ring member 20, the thickness of the drumhead 10 is between 0.3 mm and 0.5 mm, and a mesh size of the drumhead 10 is between 40T and 60T so that the drumhead 10 is thick enough to provide good sound performance and not easy to be damaged. The thickness of the ring member 20 is between 0.1 mm and 0.3 mm (preferably is between 0.15 mm and 0.2 mm), and a difference of the thickness of the drumhead 10 and the thickness of the ring member 20 is larger than or equal to 0.2 mm. In this embodiment, the thickness of the drumhead 10 is 0.4 mm, the mesh size of the drumhead 10 is 50T (which means there are 50 meshes per linear centimeter), and the thickness of the ring member 20 is 0.188 mm, which is changeable to meet different requirements.
The drumhead assembly 1 further includes a frame member 30 being annular, and the frame member 30 is disposed around the drumhead 10 and the ring member 20 and integrally connects the drumhead 10 with the ring member 20. The frame member 30 is configured to be abutted against a drum hoop 2 so as to stretch the drumhead 10, which has a simple structure and is easy to manufacture. The ring member 20 is in surface contact with the drumhead 10 and partially covers a plurality of meshes of the drumhead 10, and the ring member 20 is configured to be disposed between the drumhead 10 and a drum shell 3, as shown in
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
