Drum Accessory

Abstract

A stop and dampening pillow are provided inside a bass drum with the dampening pillow engaging the batter head (player's side) but prevented from touching or engaging the resonant head (audience side) by the stop. The stop may be a single piece device, such as a wooden circular segment, or an adjustable device for multiple drum diameter sizes.

Claims

1. A resonation enabler device for a bass drum, wherein the bass drum has a cylindrical-shaped shell having a curved inside surface of a first radius, a resonant head on a first side of the shell, and a batter head on a second side of the shell opposite of the resonant head, device comprising: one or more retainers attached towards a bottom area of the curved inside surface of the shell; and one or more rigid stops rigidly affixed to the one or more retainers, having a minor segment shape defined on a lower edge conformant to the curved inside surface of the shell and defined on an upper edge by a chord across the cylindrical shape; thereby defining a first horizontal space between the batter head, and portion of the inside surface of the shell, and the one or more rigid stops configured to receive a dampening pillow and to press the dampening pillow firmly against a lower inside surface of the batter head; and defining a second horizontal space between the resonant head, a portion of the inside surface of the shell, and the one or more rigid stops to prevent a dampening pillow or the one or more rigid stops from contacting the resonant head.

DETAILED DESCRIPTION OF ONE OR MORE

Exemplary Embodiment(s) of the Invention

[0014] The present inventor has recognized and solved several unrecognized and unsolved problems in the art regarding dampening bass drums, such as the tandem “pancake” or “woofer” arrangements described in the foregoing paragraphs. One of the problems with this design was there was not enough energy put forth by the primary bass drum to adequately excite the pancake bass drum at a proper volume without putting a microphone in front of the pancake bass drum, making it a configuration that was not useful for performance venues where microphoning and amplifying the bass drum was useful or desired.

[0015] The present inventor, realizing these shortcomings of the products available on the market, has developed and tested a resonance enabling device, potentially to be marketed as Rez-Enabler [TM], which provides both a dry and a resonant sound from a bass drum at the same time. The device uses an adjustable “stop” to hold the dampening pillow against the batter head (side being hit with a beater) and allows the resonant head (audience side) to freely vibrate. It prevents the dampening pillow from coming into contact with the resonant head, as could happen with the dampening technique without this new device. In a performance or recording situation where there is sound reinforcement, the new device can be used in conjunction with an internally mounted microphone for the batter head, which there are several manufacturers already making, and optionally, a second microphone positioned on the outside of the resonant head.

[0016] In at least one embodiment according to the present invention, the stop member will be of a partial circle shape, having an arc-shaped edge that fits an interior of a specific drum size shell and an essentially straight top edge, thereby defining a segment of a circle, and it will have two more tracks which are oriented in a line from the batter head to the resonant head to adjust the depth of dampening. In at least one embodiment, where the tracks attach to the stop member, there may be provided some side-to-side adjustments to accommodate different bass drum diameters/sizes when the stop is of an adjustable size. The dampening pillow can be of any conventional dampening pillow type, or one especially designed for this purpose, such as down-filled, bead-filled, and synthetic-stuffing filled pillows.

[0017] Turning now to FIG. 1, a photograph of a prototype according to the present invention is shown in which a stop 101 in attached 102 to the shell 100 of a typical bass drum in the interior 15. This photograph is taken from the batter head perspective (player's side) with the batter head removed for illustration. Typically, there are several drum head attachments 12 around the outside edge of the shell 100 for attaching the heads. The fasteners used to attach these 12 to the shell 100 typically penetrate the shell, with one end of the fastener presenting inside 15 the bass drum. In this example embodiment, these pre-existing fasteners are used to attach 102 brackets which hold the stop 101 firmly in place, without requiring additional drilling into or through the shell 10. Other embodiments may use other attachment devices, such as hook-and-loop fastener strips, removable glue fasteners (e.g., Command [TM] available from 3M corporation of Minneapolis, Minn.), etc.

[0018] A dampening pillow reception space 13 is created between the stop 101 and the batter head (not shown in FIG. 1), with a separation space 14 between the stop 101 and the resonant head 11.

[0019] FIG. 2 shows more details of such a stop 101, which in this example is made from about 1″ thick wood and retained 102 using L-brackets secured between the shell 10 and the stop 101 using pre-existing holes and fasteners (bolts, nuts and washers), as shown. In other embodiments, a track at each retainer position running between the two heads and attached to the shell may be employed, and the stop may connect to the tracks to allow for sliding adjustability of the two spaces 13, 14 created between the stop and the heads.

[0020] FIG. 3 provides a perspective of the example prototype shown in FIG. 2 as taken through the port in the resonant head 11, looking down onto a dampening pillow 101 which is received into the dampening pillow reception space 13.

[0021] FIG. 4 illustrates a complete bass drum with a transparent batter head 40 installed and a resonant dampening pillow 300 received into the space 13 and firmly held against the batter head 40 by the stop (not visible in this view). The pillow is prevented from making physical contact with the resonant head 11 according to the separation space 14.

[0022] FIG. 5 provides a simplified schematic of a bass drum in which hidden features are shown in broken (dashed) lines. The shell 10 has a resonant head 11 and a batter head 40, and within its interior volume 15, a stop 101 is affixed to the shell to divide the lower portion into a space 13 for receiving a dampening pillow 300 and pressing the pillow against the batter head, and a space 14 for isolating the resonant head 11 from contacting or being affected by the dampening pillow 300.

[0023] While the foregoing example embodiment referred to a prototype in which the stop was constructed from wood, other materials may be used to realize the stop such as plastic, composite wood, fiberboard, and metals. The foregoing single-piece segment-shaped embodiment is merely an example within the invention possibilities. Another example embodiment which could be adjustable to fit a plurality of drum sizes is shown in FIG. 6. A plurality of fins or panels 600 are provided connected to a strip, such as by pivoting fasteners 601, so allow curving them to fit into a smaller drum 610, medium size drum 611, or larger size drum 612. This embodiment would allow minimal manufacturing and stocking to satisfy customers with various sizes of drums rather than having a separate model for each size of drum. In another variation of this embodiment, the panels or fins are attached to a single, bendable (flexible) base which would eliminate the need for the pivoting fasteners 601.
