Claims (14)
1. A device for producing sound vibrations of a frequency effective to repel pests comprising a housing member and a sound directing means formed in said housing; said sound directing means constituting a flared cavity; a first bore formed in said housing and opening into said cavity; a fluid je producing means positioned within said first bore and projecting into said cavity; a second bore formed in said housing coaxial with said first bore a resonator means positioned in said second bore and linearly spaced from said jet producing means; a rigid and nondeformable air modulating foil formed with said housing and extending transverse to the axis of said fluid jet producing means and resonator means; and said airfoil extending into the space between said jet producing means and said resonator means.
2. The device of claim 1 wherein said fluid obstruction means is provided with a jet receiving cavity.
3. * The device of claim 1 which further comprises a means to continuously supply fluid to said jet producing means.
4. The device of claim 3 wherein the means for supplying fluid to said jet producing means further includes means for supplying pulsations to the fluid passing said jet producing means.
5. The device of claim 1 including means or producing cyclic and continuous variations in amplitude of the vibrations.
6. The device of claim 5 wherein the means for supplying fluid to said jet producing means includes means for pulsating the fluid delivered to the jet producing means.
7. The device of claim 6 wherein said pulsating means includes an expansible chamber air compressor.
8. The device of claim 7 wherein said resonator is mounted upon and directly connected to said air compressor.
9. The device of claim 7 wherein said resonator is mounted upon the air compressor and said jet producing means is in alignment with the expansible chamber of the compressor.
10. The device of claim 6 wherein the pulsations are cyclic and produce a cyclic variation in amplitude of at least twenty -five percent.
11. The device of claim 9 wherein the variation in amplitude is at leas t eighty percent.
12. The device of claim 6 wherein said means for passing the fluid from the compressor to the resonator is a short straight passageway.
13. The device of claim 12 wherein said fluid jet obstruction means extends into said cavity about 0. 25 inches and is about 0. 094 inches thick.
14. The device of claim 13 wherein said fluid obstruction means is provided with a jet receiving cavity having a diameter of about 0. 130 inches and a depth of about 0. 080 inches and said fluid jet producing means is provided with an orifice having a diameter of about 0. 080 inches.
