Abstract
A loud speaker group includes loud speakers which are equipped with joints on their front sides, and on their back sides, each is equipped with a mount for connectors with which the individual loud speakers can be connected to one another. For facilitating their assembly, the mount comprises two legs that are attached to the back side of the loud speaker box and enclose a channel in which the connector is displaceably movable. At its one end the mount has a row of holes for receiving a pin that extends through a hole on one end of a connector belonging to the adjacent loud speaker box and has at its other end a manually actuated spring-loaded snap-in pin. The snap-in pin is insertable through another hole disposed in front of the other end of the connector. One guide unit on each side of the snap-in pin limits the channel and are arranged perpendicular to the direction of movement of the connector and form guides for the connector. The loud speaker boxes are pre-assembled on the ground and then automatically self-adjust to the desired angle position when they are lifted to their work place.
