Sound modification device for percussion instruments

Abstract

The invention is a sound modification device used for a percussion instrument. It is comprised of a rigid body, interchangeable absorbent inserts, and a magnet. Once assembled and placed on the skin of a drum, these three pieces work together to make a highly effective and versatile damper to eliminate unwanted ranginess when drum is struck. The damper can be slid around the perimeter of the drum until the desired sound is achieved. The weight of the damper body adds mass to the drum, the magnet adds pull to the rim of the drum to hold the damper, and the absorbent inserts tailor the amount of dampening desired by the musician.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to the damper in more detail in FIG. 1; is an upside down perspective view of the damper according to one embodiment of the present invention and is not intended to limit the scope of the present invention. The damper 10 is shown having at least one rigid surface 12 attaching to at least one flexible surface 14. The present device will be described more with FIGS. 1 thru 9 and may be used in any appropriate application with sound producing equipment.

In further detail, still referring to the damper of FIG. 1; The rigid surface 12 may be wood, stone, hard plastic, alloy, or any sufficiently durable surface, but most preferably a metal surface. The rigid surface 12 could be wavey, flat, holed, angled, textured, or any combination of these, but most preferably a smooth and flat surface. The flexible surface 14 could be cotton, synthetic leather or any combination of soft fibrous materials, but most preferably leather. The flexible surface could be of any weight, size, color, or thickness.

The construction details of the damper as shown in FIG. 1;

The rigid surface 12 may be any shape: oval, round, square, triangular, etc, but preferably rectangular in shape. The size of the rigid surface 12 could be, but is not limited to, 1⅞ inches wide×2¼ inches long×⅝ inch thick with rounded corners. The flexible surface 14 could be constructed out of one or more pieces of leather or a combination of leather and metal or plastic or both. The leather could be attached to a ferrous material and be attracted to the integrated permanent magnet in the said damper. The flexible surface 14 could be attached to the rigid surface 12 by glue, screws, or hook and loop or another magnet. The flexible surface 14 could be at least one piece of leather and arranged in any way with the magnet 16.

Referring now to the damper in FIG. 2; which shows the damper 10 with an inside view of the rigid surface 12.

In further detail, still referring to the damper of FIG. 2; The rigid surface 12 could be the base.

The construction details of the damper as shown in FIG. 2; The rigid surface 12 could be constructed in pieces but most preferable one solid piece.

Referring now to FIG. 3; of the damper 10; the magnet 16 could occupy all or part of the surface area of the base 12 but it not limited to this form. The magnet 16 could be dipped and or coated with any other material: rubber, plastic etc. The magnet 16 could be 1½ inches long×¼′ inch wide×¼ inch thick with a 7.1 radius 17, glued, screwed, or adhered in any way to the rigid surface 12.

Referring now to FIG. 4; Still referring to the damper 10, the length of the perimeter of the rigid surface 12, could be curved or straight but preferably curved at a radius 13 of 7.124 in a way to conform to the inside shape of a standard snare drum rim 22.

Referring now to FIG. 5; Still referring to the damper 10 the vertical slot angle 26 could be preferably 105 or 15 degrees, or any angle around the perimeter of the present device 10 that fits snuggly inside any rim 22 of any drum. The magnet 16 could releasably attach itself to the inside of the rim 22. With the addition of a precise radius arc and vertical slot angle 26 the damper can maintain a secure fit even without the use of a magnet for non-ferrous snare drum rims.

Referring now to FIG. 6; this is the distant perspective view of the damper 10 within the scope of a full sized drum 30, rim 22 and drumhead 31. FIG. 6 also shows that the damper can be slid 32 via the slot 26 to desired spot on the drum 30.

Referring now to FIG. 7; Still referring to the damper 10 this alternate damper 44 could have this embodiments and could take many different forms with the materials and ideas listed thus far. FIG. 7 shows a backside perspective view of a movable or floating magnet 41.

In further detail, still referring to the damper of FIG. 7; the damper 44 when flipped over, gravity will pull the magnet 41 downward 49. This damper idea 44 would not need the slot to be cut in the rigid material in order to secure to the rim of a said drum. A dampening material 45 could be permanently affixed to the rigid base 46 and turned over depending upon desired sound. The magnet 41 will make the proper connection to the metal rim of the drum similar to FIG. 6 but without the slot configuration.

In even further detail, still referring to the damper of FIG. 7; the damper 44 can move along inside of drum rim similar to damper 10, but will only work for ferrous materials. This damper 44 could be manufactured more easily and sold for the least amount.

Method of Use

Place the damper on the inside of the drum, inserting it along the rim of the said drum. When a drummer strikes the drumhead with a stick, the damper is meant to contact the drum membrane or skin directly. The damper takes the dissonant sounding resonance of the drumhead and pinpoints the unwanted frequency or unappealing “ring” of the drum. The damper has a slot that accepts the rim of the drum which is used for sliding the damper along the inside of the drum changing the sound as played until finally settling on the best tone and spot on the drum. From there, the drummer can further detail his sound with the inserts of different materials weights and textures. The weight of the damper in conjunction with the magnet's pull to the rim of the drum, keeps the said device from moving, and thus achieves the necessary adhesion without the need for clumsy attachments that may bend, break or strip, or, gooey gels that may loose stickiness by picking up lint or stain the drumhead. Also there is a specifically designed slot that will work on most of the current non ferrous or alloy rims on the market today. This is secured not by a magnet but by the precise geometry of the slot leveraging against the back of the drum rim to achieve a secure and reliable bond on every hit to the drum. To take off, it simply needs to be lifted from the back of the damper. The sliding effect works just as well with these allow rims as the ferrous rims.

Advantages

The first advantage of the damper is that it offers a range of sound modifications for a percussion instrument “quickly” and simply. Within seconds the drummer can decide the best place for the damper while hitting the drumhead with a stick in one hand and moving the magnetized damper around the perimeter with the other. The second advantage is that it is “robust” in construction and free from wearing out its parts. Made almost entirely from one piece of metal or rigid material it could last an extremely long time. The third is that the damper has a “slot” to accept non-ferrous rims and attach without clumsy screws or latches or glues or hook and loop. The fourth advantage is the damper can be taken off in the same fashion and removably adhered to the side of the metal drum for “storage”. The fifth advantage is that the damper can accept “interchangeable surfaces” and materials hard or soft to more precisely tailor the specific kind of unwanted drum ring sound. The last advantage is that the “weight” of the present device adds mass to the drum itself, and once attached, turns a cheap snare drum, for instance, into a heavier more expensive and solid sounding one.

In a broad embodiment, the present device is an invention for modifying the sound made by a vibratable surface of a percussion instrument. The invention should not be limited by the above described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention as claimed.
