초록 ▼

The invention is an modified audible signal, such as a piezoelectric noise-making and audible signaling device, which further includes a hydrophobic covering material, such as polytetrafluoroethylene (PTFE). The hydrophobic covering material is known to be water resistant, but does not effect the sound of the audible signaling device, thereby delaying or preventing the failure of the audible signaling device from water corrosion.

대표청구항 ▼

We claim: 1. A noise-making assembly comprising: a piezoelectric transducer; a sound-amplifying housing adjacent the transducer, the sound-amplifying housing enclosing a space communicating with the transducer for receiving sound waves from the transducer, the sound amplifying housing further having a front face, said housing further comprising at least a first cavity, wherein said first cavity is adjacent said piezoelectric transducer and amplifies sounds emitted by the piezoelectric transducer; a water resistant, sound permeable barrier adjacent to said front face adjacent the first cavity for preventing water from entering the first cavity and affecting the piezoelectric transducer; and a water resistant, hydrophobic fastener, said fastener mating with said sound-amplifying housing adjacent the first cavity for preventing water from entering the first cavity and affecting the piezoelectric transducer; wherein the water resistant sound permeable barrier is constructed of polytetrafluoroethylene. 2. The noise making assembly of claim 1, wherein the water resistant, sound permeable barrier is attached to the front face by a sonic weld. 3. The noise making assembly of claim 1, wherein the water resistant, sound permeable barrier is attached to the front face by a hot melt. 4. The noise making assembly of claim 1, wherein the water resistant, sound permeable barrier is attached to the front face by a silicone adhesive. 5. The noise making assembly of claim 1, wherein the water resistant sound permeable barrier is integrally attached to said water resistant, hydrophobic fastener. 6. The noise making assembly of claim 1, wherein the water resistant, hydrophobic fastener threadingly engages said sound-amplifying housing. 7. The noise making assembly of claim 1, wherein the front face of said sound amplifying housing includes at least one aperture. 8. The noise making assembly of claim 1, wherein the front face of said sound amplifying housing comprises a grill. 9. The noise making assembly of claim 1, wherein the front face of said sound amplifying housing is constructed of polytetrafluoroethylene. 10. The noise-making assembly of claim 1, further comprising a second cavity adjacent the first cavity, wherein the second cavity further amplifies sounds emitted by the piezoelectric transducer.
