Description

Technical Field

[0001] The present invention relates to the technical field of electronic musical instruments, in particular to a virtual electronic drum and a use method thereof. Background Art

[0002] In today's society, more and more young people have musical dreams, but the price of musical instruments is not cheap, especially large instruments like drums, which brings great difficulties to those who have musical dreams and band dreams. In modern bands, drummers occupy an important position, and their role is equivalent to that of the conductor in a symphony orchestra. This is very obvious in every modern band today.

[0003] At present, the drum sets and electronic drums on the market are large and inconvenient to carry, which restricts improvisation and stage performances and is not conducive to the development of improvisation and stage performances. To address this problem, we proposed a wireless virtual electronic drum design consisting of only a posture acquisition part and a small host. By using a drumstick with a posture sensor to hit different drums in the calibrated range, different sounds can be made. The different accelerations and different sound volumes can achieve the performance function of ordinary drum sets. There are few similar products on the market, and there is no mature design solution yet. Summary of the invention
