Noise producing toy structure

1. A noise producing toy structure comprising:

a toy comprising an outer wall, the outer wall defining an inner space;

a sealed cavity and a chamber disposed in the inner space;

an opening in the outer wall for passing ambient fluid into the chamber;

a noise producing element placing the cavity in fluid communication with the chamber;

wherein an inner wall structure is disposed in the inner space for defining the sealed cavity; and

wherein a plane bisects the toy into a first portion proximal to the opening and a second portion distal from the opening, the inner wall structure being disposed in the second portion.

2. The noise producing toy structure of claim 1 , wherein the opening is disposed at an axis collinear with a longitudinal axis of the noise producing element.

3. The noise producing toy structure of claim 1 , wherein the cavity is larger than the chamber.

4. A noise producing toy structure comprising:

a toy comprising an outer wall, the outer wall defining an inner space;

a sealed cavity and a chamber disposed in the inner space;

an opening in the outer wall for passing ambient fluid into the chamber;

a noise producing element placing the cavity in fluid communication with the chamber;

wherein the noise producing element is disposed into the sealed cavity, the cavity having a width slightly larger than a length of a free portion of the noise producing element.

5. The noise producing toy structure of claim 4 , wherein the cavity is larger than the chamber.

6. The noise producing toy structure of claim 4 , wherein the opening is disposed at an axis collinear with a longitudinal axis of the noise producing element.

7. A noise producing toy structure comprising:

a toy comprising an outer wall, the outer wall defining an inner space;

a sealed cavity and a chamber disposed in the inner space;

an opening in the outer wall for passing ambient fluid into the chamber;

a noise producing element placing the cavity in fluid communication with the chamber;

wherein an inner wall structure is disposed in the inner space for defining the sealed cavity; and

wherein the inner wall structure comprises a first and a second spaced-apart side walls, the sidewalls defining the opening.

8. The noise producing toy structure of claim 7 , wherein the noise producing element protrudes into the cavity.

9. The noise producing toy structure of claim 7 , wherein the noise producing element protrudes into the chamber.

10. The noise producing toy structure of claim 9 , wherein a side wall comprises a stub wall disposed between a free end of the noise producing element and the opening, the stub wall hindering access to the noise producing element to resist unintended removal of the noise producing element.

11. The noise producing toy structure of claim 7 , wherein the opening is disposed at an axis collinear with a longitudinal axis of the noise producing element.

12. The noise producing toy structure of claim 7 , wherein the cavity is larger than the chamber.

13. A noise producing toy structure comprising:

a toy comprising an outer wall, the outer wall defining an inner space;

a sealed cavity and a chamber disposed in the inner space;

an opening in the outer wall for passing ambient fluid into the chamber;

a noise producing element placing the cavity in fluid communication with the chamber;

wherein an inner wall structure is disposed in the inner space for defining the sealed cavity; and

wherein the inner wall structure comprises a planar wall.

14. The noise producing toy structure of claim 13 , wherein the opening is disposed at an axis collinear with a longitudinal axis of the noise producing element.

15. The noise producing toy structure of claim 13 , wherein the cavity is larger than the chamber.
