摘要:
A percussion instrument includes: a cylindrical shell portion (30) having an open upper surface side; and a drumhead (10) stretched to be installed on the upper surface side of the shell portion (30), wherein the drumhead (10) includes: a membrane (11, 12) formed of a membranous material, having a struck head portion (11a, 12a) configured as a striking face to be struck by a performer and an outer periphery (11b, 12b) located on an outer circumferential side of the struck head portion (11a, 12a); and an annular frame (20) formed of a resin material and having the outer periphery of the membrane (11, 12) fixed thereto, and the drumhead (10) is integrally formed by the membrane (11, 12) and the frame (20) by injection molding.
摘要:
A snare drum (10) has a hollow cylindrical shell (11), a batter head (12) mounted on one end of the shell (11), a snare side head (13) mounted on the other end of the shell (11) and a snare wire (14) whose both ends are held by the both sides of the shell (11) to span across the surface of the snare side head (13). The snare side head (13) has a plurality of through-holes (13c). As a result, the snare drum (10) reduces sound volume while maintaining natural timbre and feeling of striking a snare drum.

Die Erfindung betrifft eine Trommel (01) zur Erzeugung eines lauten rhythmischen Geräusches, umfassend einen Klangkörper (03) aus Kunststoff und eine Membran (02) aus Kunststoff. Die Membran ist einstückig mit zumindest einem Teil des Klangkörpers (03) ausgebildet und durch eine nach außen gerichtete Wölbung dauerhaft entgegen der Aufschlagrichtung gespannt. Der Klangkörper (03) kann einen der Membran (02) gegenüberliegend angeordneten Trommelboden (22) umfassen.
摘要:
An improved drumhead comprising a substantially annular hoop having a generally planar upper member spaced apart from a generally planar lower member, a circumferential inner rim and a circumferential outer rim. Also provided is a film material or membrane for constituting a drumming surface, which extends flat across the area defined within the circumferential inner rim and the circumferential outer rim. Integrally formed with the film material or membrane of the drumming surface is an annular shoulder, which extends at its base between the planar upper and lower members in a co-planar orientation with the annular hoop. The drumhead is adaptable for use with a large variety of percussion instruments including toms, snare drums, bass drums, tambourines, congas, bongos and many other types of ethnic and other drums.

Also provided is a film material or membrane, which is generally co-planar with the annular hoop, for constituting a drumming surface, which extends flat across the area defined within the circumferential inner rim and the circumferential outer rim. The drumhead is adaptable for use with a large variety of percussion instruments including toms, snare drums, bass drums, tambourines, congas, bongos and many other types of ethnic and other drums. The invention can also be employed separately as a hand held drum with the flat annular hoop section of the instrument functioning as a drumshell.
摘要:
A diaphragm for producing sound includes at least one layer of a union fabric woven from a plurality of yarn filaments of plural kinds. The plural kinds of the yarn filaments have elongations different from each other. The plural kinds of the yarn filaments are arranged in a predetermined regular order in both warp and weft directions.
摘要:
A head for a drum or similar musical instrument comprising a synthetic plastic sheet material (12) and a synthetic fabric material (10) having a random fiber orientation which is laminated thereto. The synthetic plastic sheet material remains the primary tension load carrier while the fabric material having nonorientated fibers is laminated thereto to distribute load without transferring stress into the plastic sheet material. thereby reducing the tendency of the plastic sheet material to dent as well as damping undesirable overtones, and to provide an improved brush surface. The synthetic fabric material is preferably impregnated with a water-based resin emulsion system to insure that the nonorientated individual fibers are elastomerically bonded together, thereby increasing the fabric materials' intralaminar integrity and to further enhance the tone quality of the laminated head. Lamination and impregnation in this manner provides a laminated head having an improved sound by increasing resonance and projection with a reduction of harmonic dissonance and provides a playing surface having improved brush response, thereby also resulting in improved brush sound.
