Patent ID: 7882926

Claim:
A system for producing a sound wave, comprising: at least one detonation tube apparatus, comprising: at least one detonation tube having a closed end and an open end; at least one detonator having at least one spark initiator and an ignition point substantially located at the at least one spark initiator; and a fuel mixture supply subsystem for supplying a fuel-oxidant mixture to said at least one detonator, said fuel-oxidant mixture comprising a fuel and an oxidant, said fuel mixture supply subsystem maintaining a predetermined mass ratio of said fuel versus said oxidant and maintaining a predetermined flow rate of said fuel-oxidant mixture to achieve detonation characteristics, said detonation characteristics depending on length and diameter characteristics of said at least one detonator, said ignition point being positioned within said at least one detonator such that said fuel-oxidant mixture flows through said ignition point into said at least one detonation tube via the closed end; and at least one timing control mechanism for controlling the timing of said at least one spark initiator, said at least one spark initiator initiating at least one spark within said at least one detonator at said ignition point while said fuel-oxidant mixture is flowing at said predetermined flow rate through said ignition point of said at least one detonator thereby producing a detonation impulse at said ignition point that propagates into said closed end of said at least one detonation tube thereby initiating a detonation wave at the closed end of said at least one detonation tube, said detonation wave propagating the length of said at least one detonation tube and exiting the open end of said at least one detonation tube as a sound wave.
