LOUDNESS PREVENTION TOOL
Document Type and Number:
Japanese Patent JPH10164199
Kind Code:
A
Abstract:

To improve the pleasant use of a portable telephone set even in a noisy environment such as the inside of a train or a tram, etc., by placing the telephone set at its place of a cover body and covering the mouth of a user by the cover body with the user's ear kept attached to a speaker part of the telephone set.

A case-shaped loudness prevention tool has an almost U-shaped section that is continuously extended in its lengthwise direction and uses a thin rubber material, for example. Thus, this tool can be bent in a smaller size with its open part set inside. When the tool is used, it's freely unfolded into its original case shape by the restoring force of the rubber material. Then a portable telephone set is set at a placing part 2 prepared at an upper part of the tool, and the mouth of a user is covered with a cover body 1 prepared at a lower part of the tool. Under such conditions, the user talks on the portable telephone. Furthermore, a through hole 3 is drilled at the case end part so as to extend the antenna of the telephone set kept inside the case.
