Abstract
Abstract A sound-producing toy having a hollow body formed of resilient material, whereby when the body is depressed and deformed by a player, this action produces a honking sound. The body envelops an air-filled cavity at one end of which is an air-intake valve whose actuating element is outside the body so that when the element is actuated by the player, air is admitted into the cavity. Also disposed in the cavity is a sound producer having an air outlet normally closed by a membrane which is partially secured to the outlet so that when the body is depressed by the player, the resultant increase in internal air pressure above ambient is exerted against the membrane and causes deflection thereof to permit air to escape from the outlet. The escaping air causes the membrane to vibrate to produce a honking sound. The air expelled through the outlet creates a partial vacuum in the internal cavity which acts to maintain the body in its deformed state. But when the player operates the actuating element of the air-intake valve, air is admitted into the cavity and the body resumes its normal state.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
237 words
A sound producing toy comprising: (a) A contoured hollow body is that of a hand propelled toy vehicle having a predetermined normal shape further including a chassis on which the body is mounted and a set of front wheels and a set of rear wheels, the body being formed of resilient material which envelops an internal cavity; (b) A normally closed air intake valve disposed in the cavity and said valve having an actuating element extending outside the body which when manually actuated admits atmospheric air into the cavity; (c) An air outlet disposed in the cavity covered by a membrane said membrane having one end joined adjacent the outlet and having a deflectable section that is free of the outlet to form a vibratory element having a natural frequency in the sonic range, whereby when the body is manually distorted by a player, the resultant increase in internal pressure in the cavity is exerted on the free section to deflect it to permit the escape of air from the cavity, the rush of escaping air exciting said vibratory element into vibration to produce a sound that depends on said natural frequency, the escaped air from the cavity producing a negative pressure therein which acts to maintain the body in its distorted shape until the actuating element is actuated by the player to admit air into the cavity to cause the body to resume its normal shape.

Claim 3
Dependent Claim
20 words
A toy as set forth in claim 1, wherein said vibrating element has a natural frequency producing a honking sound.
Claim 4
Dependent Claim
82 words
A toy as set forth in claim 2, wherein said air-intake valve is provided with a cylindrical casing having at one end an air inlet port exposed to the atmosphere and at the opposite end an air outlet port communicating with the cavity, and a valve member within the casing mounted on a rod extending through the air inlet and urged by a spring against the inlet port to close the valve which is opened only when the rod is axially displaced.
Claim 5
Dependent Claim
22 words
A toy as set forth in claim 3, wherein said rod is coupled to a fifth wheel acting as the actuating element.
Claim 6
Dependent Claim
31 words
A toy as set forth in claim 4, wherein said valve is disposed at the rear of the body and the fifth wheel is disposed at the rear of the vehicle.
Claim 7
Dependent Claim
30 words
A toy as set forth in claim 5, wherein the fifth wheel and wheels in the front and rear sets are formed of the same resilient material as the body.
