Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
94 words
An accessory device for a gas balloon having a balloon neck comprising: a sealing head means for insertion in sealing-tight manner into the balloon neck; and a loudspeaker mounted in conjunction with said sealing head means and adapted to be driven by an electro-acoustic control unit for radiating sound into the interior of the gas balloon, wherein the loudspeaker is connected by electrical connecting conductors to an external electromechanical coupling means for electrical connection of the loudspeaker to an electro-acoustic control unit, the electro-mechanical coupling means being mechanically connected to the sealing head means.
