An electronic percussion device including a drum shell, a drumhead as striking surface, vibration sensors, with a peripheral and a central vibration carrier. The vibration carriers abut against the drumhead to convey vibrations therefrom to the sensor(s). The central vibration carrier is a helicoidal spring. The peripheral vibration carrier is a rigid body of solid material supported by peripheral sensors disposed thereunder. The two electrical leads of each one of the peripheral sensors are correspondingly coupled in parallel to produce only two common output leads. An electronic sound module is configured to sample the sensors and employs software procedures to detect percussion strokes delivered on the drumhead, and to generate sounds accordingly. The software procedures use the averaged and aggregated signals to provide accurate detection of position and intensity of a drum stroke. Alternative embodiments of the device use only a peripheral vibration carrier or only a central vibration carrier.

1. An electronic percussion device in an electronic percussion system, the electronic percussion device comprising: a drum shell having a top opening and a shell interior,a drumhead having a striking surface and a drumhead bottom surface disposed opposite thereto, where the striking surface is stretched over the top opening of the drum shell and is configured to receive a percussion stroke thereon,a sensors support coupled to the drum shell in the interior thereof,at least one sensor disposed on the sensors support,a peripheral carrier disposed in the shell interior and configured as a rigid body made of solid material having a peripheral carrier top edge and a peripheral carrier bottom edge, where the peripheral carrier bottom edge is supported by the at least one sensor, and the peripheral carrier top edge is biased by the drumhead bottom surface towards the at least one sensor,whereby the peripheral carrier is configured to transmit vibrations received on the striking surface to the at least one sensor. 2. The electronic percussion device of claim 1, wherein: the peripheral carrier top edge abuts in contact against at least one portion of the drumhead bottom surface. 3. The electronic percussion device of claim 1, wherein: the peripheral carrier top edge abuts against the drumhead bottom surface to form a predetermined path of contact via which vibrations induced in the drumhead are communicated to the peripheral carrier and to the at least one sensor. 4. The electronic percussion device of claim 3, wherein: the predetermined path of contact forms a shape having a closed curvilinear path. 5. The electronic percussion device of claim 1, wherein: the peripheral carrier is configured as a rigid hollow body made of solid material extending from the drumhead bottom surface to the at least one sensor, andthe peripheral carrier top edge is disposed sufficiently adjacent to the drum shell to avoid percussion strokes impinging directly thereover. 6. The electronic percussion device of claim 1, wherein: the peripheral carrier is biased by the drumhead onto the at least one sensor which is disposed on the sensors support in a configuration allowing at least one degree of freedom of motion of the peripheral carrier, which vibrates and communicates vibration. 7. The electronic percussion device of claim 1, wherein: the at least one sensor includes a plurality of sensors, each one sensor out of the plurality of sensors has a first sensor lead and a second sensor lead, the first sensor leads of the plurality of sensor leads are electrically coupled to form a common first lead,the second leads of the plurality of sensors are electrically coupled to form a common second lead, anda single electrical output signal derived from the plurality of sensors communicated via the common first lead and the common second lead. 8. The electronic percussion device of claim 1, wherein: a central sensor is disposed on the sensors support,a central carrier disposed on the sensors support comprises a mechanical spring having a first end and a second end, andthe spring first end is coupled to the central sensor and the spring second end is biased against the drumhead bottom surface. 9. An electronic percussion device in an electronic percussion system, the electronic percussion device comprising: a drum shell having a top opening,a drumhead disposed in tension across the top opening to define a striking surface for receiving thereon a percussion stroke that induces vibrations in the drumhead,a bottom surface of the drumhead facing opposite the striking surface,a first means configured as a rigid body made of solid material for receiving and transmitting vibrations from the drumhead, the first means abutting against the bottom surface in a plurality of locations,a second means configured for receiving vibrations from the first means and for generating an electrical signal in response to vibrations,the first means being disposed on the second means, whereby vibration induced on the drumhead is communicated from the plurality of locations to produce a single electrical signal. 10. The electronic percussion device of claim 9, wherein: the plurality of locations at which the drumhead abuts against the first means are selected to be sufficiently close to the drum shell to avoid a percussion stroke directly over the first means. 11. The electronic percussion device of claim 9, wherein: the first means has a top edge in the shape of an annulus which abuts against the drumhead bottom surface. 12. The electronic percussion device of claim 9, wherein: the second means includes a plurality of sensors where each sensor out of the plurality of sensors has a first lead and a second lead, where the first leads of the plurality of sensors are electrically coupled to form a common first lead,the second leads of the plurality of sensors are electrically coupled to form a common second lead, noa single electrical output signal derived from the plurality of sensors is communicated via the common first lead and the common second lead. 13.
