Abstract
A concussion device for creating a low level of smoke and a selectively tuned low-toned sound, the device including a structure having a cavity, the cavity having a top opening; a first energetic charge disposed in a bottom portion of the cavity; and a member removably secured to the structure within the cavity and partially overlying the first energetic charge.
Claims20
A concussion device comprising:
- a structure comprising a cavity, the cavity having a top opening;
- a first energetic charge disposed in a bottom portion of the cavity;
- an elongated member having a length, a width, and a thickness, with the length being greater than both the width and the thickness of the elongated member, said elongated member removably secured to the structure within the cavity, the length of the elongated member extending across the cavity to partially cover a horizontal cross-sectional area of the cavity defined on a perimeter by walls of the cavity, the horizontal cross-sectional area covering the first energetic charge, said elongated member removably secured to remain substantially in place during detonation of said first energetic charge.
