ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to a music enhancing devices and, in particular, to a percussion device having an induced vibratory resonance.
BACKGROUND OF THE INVENTION
Various percussion devices have been proposed for creating music enhancing effects when struck manually or with a percussive instrument. Oftentimes, the devices are mounted as part of a drum set or clamped on an independent stand. Examples are a cowbell directly mounted on a drum as disclosed in U.S. Pat. No. 5,684,258 to Liao; a free standing cowbell as disclosed in U.S. Pat. No. 5,986,195 to DeArmas; a corrugated resonator clamped to a drum as disclosed in U.S. Pat. No. 5,986,195; and the drum mounted cymbal as disclosed in U.S. Pat. No. 2,971,738 to Way.
One particular percussion resonating device, known as a “Vibra-Slap” from Latin Percussion, Inc. and disclosed in U.S. Pat. No. 3,459,572 to Cohen, couples a hand held instrument having a ball on a lower arm that is struck on the bottom with the hand and induces a vibration response in a resonator cavity mounted on an upper arm that contains a plurality of loosely supported pins. The resonating effect simulates a periodic rattling effect associated with a jawbone commonly used with Latin American music. In addition to requiring both hands of the instrumentalist for operation, the resonation is quickly damped, lasting only about two to three seconds or less.
BRIEF SUMMARY OF THE INVENTION
The present invention provides a jawbone-type percussion instrument having an extended and rich response. The instrument comprises a support bar having a pair of extending arms integral with a center section that is clamped on an accessory mount. A jawbone resonator is fixed on the outer end of the lower arm, as opposed to the conventional upper arm, and a circular strike pad is fixed on the outer end of the upper arm. The center section is resiliently coupled with the accessory mount at an elastomeric sleeve. The pad and the resonator have substantially equal weights and cantilevered lengths. When the impact is struck with a percussive instrument such as a drumstick, long lasting vibration energy is transferred without dampening at the clamp to the resonator, effecting an extended resonating period. The effects are further enhanced by the strike pad, which comprises a low durometer impact surface laminated to a rigid disk and mutes the stick impact and provides natural rebound. Additionally, rather than occupying both hands of the instrumentalist, the momentary impact allows other percussive effects to be undertaken by the percussionist during the resonance period.
Accordingly, it is an object of the invention to provide a resonating percussive instrument having an extended resonating period.
Another object is to provide a resonating percussive instrument that may be independently mounted and played with one hand using conventional percussive devices such as drumsticks.
A further object is to provide an improved jawbone type resonating instrument that is resiliently mounted to reduce resonance dampening and prolong the desired acoustical effect.
