The cymbal assembly may be mounted using a magnetic ring configuration or a threaded pole configuration. ## Claims ### Claim 1 An electronic cymbal assembly comprising: a hi-hat cymbal mounting post; a top cymbal received by the mounting post; a hi-hat clutch received by the mounting post for coupling the top cymbal to the mounting post; a bottom cymbal received by the mounting post; an outer mounting tube rigidly affixed to a top side of the bottom cymbal, the outer mounting tube comprising a substantially hollow sleeve, the outer mounting tube further comprising a variable resistor rigidly mounted to the substantially hollow sleeve; an inner sliding sleeve tube received by the mounting post, the inner sliding sleeve tube disposed between top cymbal and the bottom cymbal, the inner sliding sleeve tube configured to be received by and to slide up and down within the outer mounting tube; the variable resistor coupled to the inner sliding sleeve tube such that when the inner sliding sleeve tube moves upwardly or downwardly with respect to the outer mounting tube, the movement of the inner sliding sleeve tube with respect to the variable resistor causes the variable resistor to send electronic messages to a sound module to trigger production of sounds. ### Claim 2 (depends on 1) The assembly of claim 1, further comprising a ring magnet received by the mounting post, the ring magnet disposed between the top cymbal and the bottom cymbal, the ring magnet magnetically coupled to the top cymbal, the inner sliding sleeve tube disposed between the ring magnet and the bottom cymbal, the inner sliding sleeve tube magnetically coupled to the ring magnet. ### Claim 3 (depends on 2) The assembly of claim 2, wherein the ring magnet is a neodymium magnet. ### Claim 4 (depends on 1) The assembly of claim 1, further comprising an input jack box mounted to the underside of the bottom cymbal, the input jack box housing electrical connections for coupling to an external sound module. ### Claim 5 (depends on 4) The assembly of claim 4, wherein the variable resistor connects to positive and negative connections of the input jack box. ### Claim 6 (depends on 1) The assembly of claim 1, further comprising a self dampening trigger system attached to the underside of the top cymbal. ### Claim 7 (depends on 1) The assembly of claim 1, the variable resistor mounted to an outer surface of the outer mounting tube. ### Claim 8 (depends on 7) The assembly of claim 7, the outer mounting tube further comprising a vertical channel, the variable resistor comprising a moveable sliding arm, the moveable sliding arm extending through the vertical channel. ### Claim 9 (depends on 8) The assembly of claim 8, the inner sliding sleeve tube further comprising an opening for receiving and retaining the moveable sliding arm such that the moveable sliding arm is moveable up and down to track up and down movement of the inner sliding sleeve tube. ### Claim 10 (depends on 1) The assembly of claim 1, the variable resistor mounted to an inner surface of the outer mounting tube. ### Claim 11 (depends on 10) The assembly of claim 10, the inner sliding sleeve tube further comprising a guiderail extending from an outer surface of the inner sliding sleeve tube. ### Claim 12 (depends on 11) The assembly of claim 11, the outer mounting tube further comprising a vertical slot for receiving the guiderail, such that the guiderail slides upwardly and downwardly within the vertical slot. ### Claim 13 (depends on 12) The assembly of claim 12, the inner sliding sleeve tube further comprising a center spring plunger, the center spring plunger extending outwardly from the inner sliding sleeve tube, the center spring plunger aligned with the variable resistor and configured to contact the variable resistor. ### Claim 14 An electronic cymbal assembly comprising: a mounting post; a foot pedal coupled to the mounting post such that when the foot pedal is depressed, the mounting post moves upwardly, and when the foot pedal is released, the mounting post moves downwardly; a top striking plate received by the mounting post, the top striking plate affixed to the mounting post such that the top striking plate moves upwardly and downwardly in conjunction with the mounting post; an outer mounting tube received by the mounting post, the outer mounting tube configured to remain stationary when the mounting post moves upwardly and downwardly, the outer mounting tube comprising a substantially hollow sleeve, the outer mounting tube further comprising a sensor rigidly mounted to the substantially hollow sleeve; an inner sliding sleeve tube received by the mounting post beneath the top striking plate, the inner sliding sleeve tube configured to move in conjunction with the top striking plate, the inner sliding sleeve tube further configured to be received by and to slide up and down within the outer mounting tube; the sensor coupled to the inner sliding sleeve tube such that when the inner sliding sleeve tube moves upwardly or downwardly with respect to the outer mounting tube, the movement of the inner sliding sleeve tube with respect to the sensor causes the sensor to send electronic messages to a sound module to trigger production of sounds. ### Claim 15 (depends on 14) The assembly of claim 14, wherein the sensor is a variable resistor. ### Claim 16 (depends on 14) The assembly of claim 14, wherein the top striking plate is a metallic top cymbal. ### Claim 17 (depends on 14) The assembly of claim 14, wherein the outer mounting tube is rigidly affixed to a bottom metallic cymbal. ### Claim 18 A device for triggering sound comprising: an outer mounting tube comprising a substantially hollow sleeve, the outer mounting tube further comprising a sensor rigidly mounted to the substantially hollow sleeve; an inner sliding sleeve tube configured to be received by and to slide up and down within the outer mounting tube, the inner sliding sleeve tube configured to be mounted to a hi-hat mounting post, the hi-hat mounting post causing the inner sliding sleeve tube to move upwardly and downwardly upon actuation of a foot pedal; the sensor coupled to the inner sliding sleeve tube such that when the inner sliding sleeve tube moves upwardly or downwardly with respect to the outer mounting tube, the movement of the inner sliding sleeve tube causes the sensor to send electronic messages to a sound module to trigger production of sounds. ### Claim 19 (depends on 18) The device of claim 18, wherein the sensor is a variable resistor. ### Claim 20 (depends on 18) The device of claim 18, further comprising a top striking plate, the top striking plate received by the mounting post, the top striking plate affixed to the mounting post such that the top striking plate moves upwardly and downwardly in conjunction with the mounting post. ### Claim 21 (depends on 18) The device of claim 18, wherein the outer mounting tube is rigidly affixed to a bottom metallic cymbal.
