DEVICE FOR UNDERWATER VOICE COMMUNICATION

摘要

The object of the invention is a device for underwater voice communication which may, in particular, be used in underwater communication between divers and scuba divers. The device is composed of a rigid body (1) to which an acoustic head (2) is attached, the latter being in the form of a thin-walled, hollow block, on the walls of which there are bends. The interior of the acoustic head (2) is connected to the interior of the body (1) via an opening. A mouthpiece (4) is attached to the body and tightly covers the part of the face which surrounds the mouth. In the lower part of the body, there is an outlet opening or openings (6), aimed at leading out into water the breathing gases that are exhaled while the user speaks to the device. The device can be also provided with a cover for the acoustic head (3) in the form of an openwork structure, protecting the acoustic head (2) from mechanical damages, and with a handle (5) allowing grasping of the device in a manner allowing it to be turned with the mouthpiece towards the mouth of the person holding it.
