A cover for keeping a liquid bottle cold is provided to produce an advertisement description, slogan and tune of a specific company through a speaker when a consumer grips or moves a liquid bottle to improve sales promotion and advertisement effect. A cover for keeping a liquid bottle(1) cold includes an inner cover(10), an outer cover(20), an operating sensor and an audio module(30). The inner cover is shaped according to the external shape of the liquid bottle such that the liquid bottle is inserted into the cover. The outer cover envelops the inner cover having a predetermined space(21) between the inner cover and the outer cover. The operating sensor is set in the space between the outer cover and the inner cover and senses a motion of the liquid bottle. The audio module generates a specific voice or tune previously stored in an IC(Integrated Circuit) chip through a speaker(33) according to the signal sensed by the operating sensor. |
