Abstract
A helix of wire having predetermined dimensions is encircled by a sleeve of selected material which conforms to the exterior surface configuration of the helix. When a gas is applied into one end of the helix-sleeve combination, an audio frequency signal appears at the other end of the helix-sleeve combination having a frequency which increases in steps proportional to the entrance pressure of the gas flowing through the helix-sleeve combination, or proportional the changes in the mass rate of flow of the gas through the helix-sleeve combination.
Claims9
A fluidic frequency generator comprising:
- a helix of wire having predetermined dimensions;
- a sleeve of selected material disposed to encircle and conform to the exterior surface configuration of said helix;
- and
- means containing a pressurized gas having a pressure greater than the atmosphere, said means being coupled to one end of said helix and said sleeve to direct said pressurized gas for flow through said helix and said sleeve from said one end to the other end of said helix and said sleeve;
- said helix and said sleeve cooperating to provide at said other end an audio frequency in response to said gas flowing through said helix and said sleeve, said audio frequency being proportional to a predetermined characteristic of said gas flowing through said helix and said sleeve.
