发明名称 Electric drum stroke counting machine
摘要 A drum beat counter that can be attached to either a conventional drum head or an electronic drum kit. The counter counts the number of beats over a given time set by the user. The drum beat counter includes a strike sensor adapted to detect the strikes and create a strike signal, a strike counter electrically connected to the strike sensor and adapted to receive the strike signal, adapted to detect strikes represented in the strike signal, and further adapted to create a count signal; and a display electrically connected to the counter and adapted to receive the count signal and present a representation of the number of strikes. This device can be used in many ways including speed counting or ensuring that the drum actually beats the number of times desired.
