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.
