The present invention relates to drum rim risers with triggers and multiple sensors, and more particularly, some embodiments relate to a rim raising device that attaches to a section of a drum rim, or peripheral area of a rimless drum to help facilitate and enhance a percussion technique by creating elevation above the drum rim, and utilizing an intensity sensitive sensor and a linear sensor for detecting and transmitting a force that strikes the device mounted on the drum to generate a predetermined sound.
The subject invention generally relates to drum rim risers.
Typically, a drum is a member of the percussion group of musical instruments. Drums consist of at least one membrane that is stretched over a shell and struck, either directly with the player's hands, or with a drum stick, or any other percussion or striking element to produce sound. There is usually a resonance head on the underside of the drum, typically tuned to a slightly lower pitch than the top drumhead. A drum rim forms a circumference atop the drum, and can be used as part of the contact surface for playing the drum and positioning the drum sticks.
It is well known that an electronic drum is an electronic synthesizer that mimics an acoustic drum kit. The electronic drum usually consists of a set of pads mounted on a stand in a disposition similar to an acoustic drum kit. Each pad has a sensor that generates an electric signal when struck.
Typically, a rim click technique involves placing a tip of a drum stick on a drum head, near the center. The shaft of the drum stick is tapped against the drum rim. This creates a dry clicking sound.
Often, a piezoelectric sensor is a device that uses the piezoelectric effect to measure pressure, acceleration, strain or force by converting them to an electrical charge. The electrical charge is proportional to the intensity of the force. A force sensor creates a change in electrical resistance when a force is applied. The change in resistance creates a voltage.
It is known that there is a need for consistent and accurate cross sticking or rim clicking, and a solution to the limitations related to rim playing in any form on a drum. The action of a drummer playing a cross sticking technique requires sufficient space above the drum to form a firm grasp on the drum stick whose tip or butt rests on the drum head. A remote drum rim, separate from the drum, and transmitting the sounds from the drum rim could provide increased playing options.
Even though the above cited drum rim raisers address some of the needs of the market, a rim raising device that enhances a percussion technique by creating elevation above the drum rim, and sensing and transmitting a force that strikes the device mounted on the drum is still desired.
According to one variant of the invention, the rim raising device attaches to a section of a drum rim to help facilitate and enhance a percussion technique. The rim raising device enables enhanced percussion techniques for electrical and acoustic drums by providing a realistic feel for the drum rim without the mechanical drawbacks and limitations that often accompany a drum rim. The rim raising device utilizes at least one piezoelectric sensor and at least one force sensor, having different functionalities to generate a signal for creating acoustic energy.
In some variants, the rim raising device may provide additional elevation and surface area to a section of the drum rim such that manipulation for a percussion technique, such as a cross stick technique, is facilitated and enhanced. Those skilled in the art, in light of the present teachings, will recognize that a cross stick or rim click technique involves placing one end of a first drum stick on a drum head, and a second end of the first drum stick on the rim. In the case of a cross stick play, a second drum stick may then strike the first drum stick and/or the drum head to produce a dry clicking sound. Thus, providing additional elevation to the section of the drum rim supporting the first drum stick produces multiple advantages, such as more space for grasping the first drum stick, more space for manipulating the first drum stick, and more configurations for generating different sounds from the drum and the drum sticks. The increased elevation and additional surface area offered by the rim raising device may also enable at least one piezoelectric sensor, at least one force sensor sensors, transmitters, wiring, and other electronic components to attach to the drum rim.
In one variant of the present invention, the configuration and positioning of the rim raising device in relation to the drum serves to create additional space between the rim raising device and the drum rim. This additional space may facilitate manipulations and control of a drum stick when performing the percussion techniques. For example, increasing the elevation of a drum stick during a cross stick or rim click technique creates more space for a body part to maneuver, and creates more variety of sounds when striking the drum or the drum stick.
In one variant, a triggering assembly detects a force on a contact portion of the drum, and triggers the subsequently generated signal to a transmitter for generating a predetermined sound. The triggering assembly comprises at least one piezoelectric sensor and at least one force sensor.
In one variant, at least one piezoelectric sensor and at least one force sensor position on the rim raising device. The at least one piezoelectric sensor is configured to convert the force of the at least one drum stick into a signal that is proportional to an intensity of the force. The at least one piezoelectric sensor is operable to measure pressure, acceleration, strain, or force produced by the drum stick striking the drum. The force creates a deformation in a piezoelectric material, such as a piezoelectric ceramic, whereby the deformation generates a voltage. The intensity of the voltage forms the signal, which transmits to a remote trigger interface into conversion to an acoustic energy.
The triggering assembly may further utilize at least one force sensor. The at least one force sensor is configured to convert the force from the at least one drum stick into either an on signal or an off signal in the form of voltage. Unlike the at least one piezoelectric sensor, which generates a voltage that is proportional to an intensity of the force, the at least one force sensor either generates a predetermined voltage, or does not generate any voltage. In this manner, the at least one force sensor may provide two novel functions.
In one function, the at least one force sensor generates a signal, comprising a predetermined linear voltage that transmits to the remote trigger interface into conversion to an acoustic energy. Those skilled in the art will recognize that the predetermined linear voltage generated by the at least one force sensor forms a different acoustic energy than a signal that is proportional to an intensity of the force, such as what the at least one piezoelectric sensor generates.
In a second function, the at least one force sensor serves as a gate or switch for actuating the at least one piezoelectric sensor. In this manner, the at least one piezoelectric sensor may be actuated to generate a signal, not through direct contact from the drum stick, but by the force expanded onto the force sensor. In some embodiments, the at least one force sensor positions above and engages the at least one piezoelectric sensor for instigating contact between the two sensors.
The at least one force sensor serves as a triggering mechanism to convert the force generated by a drum stick striking the rim raising device and the drum into a linear signal. The linear signal may then be wirelessly transmitted or sent by wire to a remote trigger interface for conversion into a predetermined sound. In this manner, the rim raising device may mount directly onto the drum rim, or serve as an independent instrument, remotely positioned from the drum. Additionally, the rim raising device may include a vibration suppression device to at least partially inhibiting vibrations and other unwanted consequences created while performing the percussion techniques.
In one aspect of the present invention, the rim raising device comprises:
In yet another aspect, the rim raising device creates additional air space between the contact portion of the arc section and the drum rim. The air space provides more space to firmly grasp the drum stick. The improved grip enables a more controlled, accurate swing of the drum stick, which is necessary for the cross stick technique and other percussion techniques.
In yet another aspect, the at least one piezoelectric sensor converts the force generated by striking the drum and the rim raising device into a signal that is proportional to an intensity of the force. The signal may then be carried wirelessly, or through a transducer wire, to a remote trigger interface via an instrument cable or wire for conversion into acoustic energy in the form of a predetermined sound.
In another aspect, a vibration suppression portion, such as a anti-vibration rubber diffusion piece, positions on the drum raising device to help inhibit at least one sympathetic vibration from at least one section of the drum or drum rim.

The present invention relates to rim raising devices and, more particularly, some embodiments relate to a rim raising device 5 that attaches to a section of a drum rim to help facilitate and enhance a percussion technique by providing additional elevation above the drum rim for enhanced manipulation of a precision mallet, detecting the intensity of a force from the drum stick striking the drum and the rim raising device 5, and wirelessly transmitting a signal from the device 5 to a remote trigger interface (not shown) for generating a predetermined sound. Unwanted vibrations, such as cross talk interference from different sections of the drum, are also partially inhibited with a vibration suppression portion 105 that attaches to the rim raising device 5. The rim raising device 5 may be utilized with a variety of drums, including, without limitation, snare drums, tom drums, electrical drums, riding toms, hi-hat stands, Djembe, and any other drum structure having a free standing accessory where additional sounds are desired or acoustical benefits can be realized. The percussion technique may include, without limitation, a cross stick technique, a rim click technique, a rim shot technique, a one-handed-roll technique, and the like.
In one variant of the present invention, referring to
The rim raising device 5 comprises an arc section 10 that is sized and dimension to contour the arc of a circumference on the drum rim (
For purposes of the rim click technique, a drum stick has a striking end that rests near the center of the drum, and a grasping end that rest on the contact portion 15. The drum stick strikes the drum to produce the desired effect. The arc section 10 comprises a sidewall 20 that elevates the contact portion 15 over a circumference of the mounting surface 30. The sidewall 20 may include a sidewall aperture 65 for wiring to pass through.
The arc section 10 may further include a mounting portion 25 for engaging the mounting surface 30. The mounting portion 25 may comprise a lower housing 90 of the rim raising device 5, opposite the contact portion 15. In one variant, the mounting portion 25 mounts onto a circumference section of the drum rim. The mounting portion 25 comprises a flange 35 that extends from the sidewall 20. The flange 35 may align with an existing flange on the drum rim. The flange 35 comprises at least one flange aperture 100 for at least partially enabling a fastener to pass through at least one threaded spacer 50. The fastener may include, without limitation, a threaded bolt, a screw, a magnet, and an adhesive. In this manner, the arc section 10 attaches to the rim raising device 5, and can be tightened onto the rim raising device 5 through an existing tension rod 55 of the drum or a supplemental tension rod 55 that comes with the rim raising device 5. At least one steel spacer (not shown) positioned on the tension rod 55, and under the flange 35 may be added or removed to create smaller elevation adjustments for the rim raising device 5.
In some variants, the mounting portion 25 may utilize additional means to secure to the mounting surface 30. The mounting portion 25 may include at least one mounting aperture 110. The at least one mounting aperture 110 is configured to enable at least partial entry of a mounting fastener for securing the arc section 10 to the mounting surface 30.

As referenced in
In one function, the at least one force sensor 120 generates a signal, comprising a predetermined linear voltage that transmits to the remote trigger interface into conversion to an acoustic energy. Those skilled in the art will recognize that the predetermined linear voltage generated by the at least one force sensor 120 forms a different acoustic energy than a signal that is proportional to an intensity of the force, such as what the at least one piezoelectric sensor 60 generates. In a second function, the at least one force sensor 120 serves as a gate or switch for actuating the at least one piezoelectric sensor 60. In this manner, the at least one piezoelectric sensor 60 may be actuated to generate a signal, not through direct contact from the drum stick, but by the force expanded onto the force sensor. In some embodiments, the at least one force sensor 120 positions above and engages the at least one piezoelectric sensor 60 for instigating contact between the two sensors 60, 120.
The force sensor 120 may include a contact strip, or a thin film force sensor 120 that may be applied onto the triggering assembly 70 through an adhesive or by painting on. The at least one force sensor 120 may further utilize a plurality of ribs 125. The plurality of ribs 125 includes rubber protrusions that extend from the triggering assembly 70 and detect the force of the drum stick striking the contact portion 15. The at least one force sensor 120 produces a linear on/off signal, rather than the signal proportional to the force, intensity dependent signal generated by the at least one piezoelectric sensor 60. In this manner, the at least one force sensor 120 serves as a gate for actuating the at least one piezoelectric sensor 60. However, in other embodiments, the at least one force sensor 120 initiates and transmits the signal to the remote trigger interface. An anchor plate 80 provides a mount for both sensors to attach to the triggering assembly 70.
The triggering assembly 70 further includes a transmitter 75. The transmitter 75 may comprise a ¼″ input jack, including a mono or stereo phono connector. A cable may carry the signal from the input jack to the remote trigger interface through a contact 115. However, in another embodiment, the transmitter 75 may include a radio frequency transmitter 75 that transmits the signal wirelessly with a radio frequency or, in some variants, through Bluetooth technology. The signal may be generated and transmitted as analog or digital. The wireless transmission of the signal helps to minimize the amount of wiring, and also allows the rim raising device 5 to be used separately from the drum. In some variants, a transducer wire 30 joins the transmitter 75 with the at least one piezoelectric sensor 60 and/or the at least one force sensor 120. A barrel clamp 45 helps secure the transducer wire 30 to a housing 40. The housing 40 provides protection to the transmitter 75 from moisture and forceful impact.
The transmitter 75 is operable to transmit the signal to a remote trigger interface. The remote trigger interface is configured to convert the signal into an acoustic energy for generating the predetermined sound. The remote trigger interface may include, without limitation, a sound module, and a midi interface. In this manner, the effects of the percussion technique may be sent and heard in real time.
In one variant, the rim raising device 5 includes a vibration suppression portion 105. The vibration suppression portion 105 is configured and positioned on the arc section 10 to help suppress a vibration. Those skilled in the art will recognize that striking the drum or the rim raising device 5 may generate a sympathetic vibration, or cross talk, which occurs when a plurality of sections on the drum are engaged almost simultaneously. The vibration suppression portion 105 helps absorb and/or disperse the vibrations from the materials and positioning on the drum and the drum raising device 5.
