1. Technical Field
The present patent document relates generally to electronic cymbals and more particularly to an electronic cymbal that includes an improved edge sensor assembly.
2. Background of the Related Art
Electronic cymbals of the prior art sometimes include a membrane switch on the edge of the cymbal to detect edge strikes or the act of “choking” (i.e. muting) the cymbal. However, membrane switches are a tough trade-off between being reliably off and requiring too much force to switch on.
Therefore, there is a perceived need in the industry for an improved sensor assembly for an electronic cymbal that reliably detects strikes.
The present invention solves the problems of the prior art by providing an electronic cymbal that includes a cover with an integrated membrane switch. More specifically, the electronic cymbal includes a frame having an edge. A cover is attached to the upper surface of the frame. A membrane switch is integrated into the cover and is positioned above the edge of the frame. The cover may include one or more layers or a resilient material, such as rubber, synthetic rubber, silicon, and the like. Because the membrane switch includes resilient material underneath it, the membrane switch is “stiffer” switch (i.e. more robust) and may be triggered without excessive pressure. As a consequence, operation of the membrane switch on the edge of the frame of the electronic cymbal is made more reliable.
These and other features, aspects, and advantages of the present invention will become better understood with reference to the following description, appended claims, and accompanying drawings where:
Referring now to
The cover 14 may include one or more layers or a resilient material, such as rubber, synthetic rubber, silicon, and the like. The cover 14 may wrap around to a bottom surface 24 of the frame 12, but is not essential that it do so.
Referring to
The second embodiment 100 includes a cover 114 is formed from hard rubber layer 114A attached to a soft rubber layer 114B. A membrane switch 122 is captured between these two rubber layers 114. Preferably, the hard rubber layer 114A is underneath the softer rubber layer 114B, but is not required. Also, the two rubber layers 114 could be of the same hardness. The term “rubber” is being used loosely herein to refer to any resilient material with rubber-like qualities. A recess, or pocket, 118 may be formed between the two layers 114 therein depending upon the thickness of the membrane switch 122 in order to accommodate the membrane switch 122.
The cover 114 is then attached to the upper surface 116 of the frame 112 of the electronic cymbal 100 like the first embodiment 10. The cover 114 may wrap around to a bottom surface 124 of the frame 112, but is not essential that it do so.
As can be readily appreciate by one skilled in the art, operation of the membrane switch on the edge of the frame of the electronic cymbal 10, 100 is made more reliable by putting a resilient material under the membrane switch 22, 122. The resilient material under the membrane switch 22, 122 (in the proposed envelope 10 or sandwich of layers 100) allows a “stiffer” switch (i.e. more robust) to be triggered without excessive pressure. Either embodiment 10, 100 may be further optimized by profiling the resilient material. For example, a set of saw tooth ridges (axially like bicycle spokes) may be formed on the top or bottom of the resilient material above or below the membrane switch 22, 122 to improve sensitivity by reducing the area exerting the pressure on the membrane switch 22, 122 for closure.
It would be appreciated by those skilled in the art that various changes and modifications can be made to the illustrated embodiments without departing from the spirit of the present invention. All such modifications and changes are intended to be within the scope of the present invention.
