ABSTRACT:
A drumhead for use in a percussion instrument is composed of multiple (e.g., two or three) plies of synthetic resin films, which are laminated together and are brought into close contact with each other when stretched across the opening of a hollow cylinder of a drum, for example. At least one air evacuation hole is formed at the center of the backside synthetic resin film or in proximity to the center of the backside synthetic resin film. Therefore, when the drumhead is stretched outwardly along a diameter direction of the opening of the hollow cylinder of the drum, remaining air between the films can be reliably evacuated from the air evacuation hole towards the exterior of the drumhead. Thus, it is possible to reduce unwanted loss in transmission of vibration between the films of the drumhead when beaten; hence, it is possible to realize good sound quality in the drum.
