Abstract
Abstract A sound emitting ball has (a) a ball having an airtight bladder with an air injection valve, (b) a housing provided within the ball on the opposite side of the bladder with respect to the valve without interferring with the airtightness of the bladder, (c) a cover for concealing the housing, (d) a detector for detecting an application of external force to the ball, (e) a sound generator for generating a sound signal according to the signal from the detector, (f) a speaker for emitting sound according to the sound signal from the sound generator, and (g) a battery power source. The detector, sound generator, speaker, and battery power source are accommodated in the housing and the sum of the weights of the housing, cover, detector, sound generator, speaker, and battery power source are adjusted to a weight which does not substantially interfere with the impact resilience of the bladder and is substantially the same as the weight of the valve.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
217 words
A sound emitting ball, comprising (a) a ball having an airtight bladder for giving impact resilience to the ball in which compressed air is charged through an air injection valve, (b) a concave housing provided within the ball on the opposite portion of the bladder with respect to the valve and contacting the surface of the bladder while keeping the airtightness of the bladder, (c) a cover for concealing an opening in the housing, (d) means for detecting an external force applied to the ball and producing a signal in response thereto, (e) means comprising of an integrated circuit for generating a sound signal according to the signal from the detecting means, (f) means for emitting sound according to the signal from said sound signal generating means, and (g) a battery power source for said above detecting means, sound signal generating means and emitting means, said detecting means, said sound signal generating means, said emitting means and said battery power source being accommodated in the housing, and such that the sum of the weights of the housing, the cover, said detecting means, said sound signal generating means, said emitting means and said battery power source does not substantially interfere with the impact resilience of the ball and is substantially the same as the weight of the valve.
Claim 2
Dependent Claim
