Fuente: Wipo "Sensorization" There is provided an electronic percussion instrument (1) including a struck surface (3a) and strike sensors (10, 20, 30, 40). The strike sensors include a central sensor (10); a plurality of peripheral sensors (20, 30, 40); a first position calculation device (S34) configured to, when an initial half wave of a strike waveform of the central sensor (10) is detected within a first predetermined time after the central sensor (10) detects a strike, calculate a first strike position from the central sensor (10) based on the initial half wave; a second position calculation device (S36) configured to calculate a second strike position based on a difference in strike detection by the plurality of peripheral sensors (20, 30, 40); and a sound production instruction device (S41) configured to instruct production of a striking sound based on the first and second strike positions respectively calculated by the first and second position calculation devices (S34, S36).
