A lighting/sound-producing device activated by an inflated balloon comprising a lamp/sounder, a battery (4), and an enclosure (5). Enclosed in the enclosure (5) is at least a lamp/sounder. The enclosure (5) comprises a gas inlet end (51), a gas outlet end (52) and a gas passage (6) connecting the gas inlet end (51) and the gas outlet end (52) to form a through passage in the enclosure (5) for gas flow. The lamp/sounder is installed in the gas passage (6) and equipped with a sealing device (2) for blocking the gas passage (6) via the sealing device (2). When a balloon is not inflated, the lamp/sounder cannot be activated. After the balloon is inflated, a pressure difference between the inside and the outside of the balloon is formed, pushing the lamp/sounder towards the outer end of the gas passage and sealing off the gas passage, and further switching on the electric circuit of the lamp/sounder activates the lamp/sounder.
