摘要： A wireless receiver having a first and second housings one of which contains a wireless signal transmission and receiving means. The other housing preferably contains a power supply and possibly a battery back-up for use in the event of a cut in the power supply. The two housings are hinged together. They are relatively movable between one position in which the two housings depend one from another so as to be mounted upon a vertical wall and another position in which the two housings are disposed one behind the other for supporting upon a horizontal surface. Preferably, in the position for mounting upon a wall, the two housings provide rear planar surfaces which are coplanar and in the other position for mounting upon a horizontal surface the two housings provide planar support surfaces for supporting them upon the horizontal surface. It is also preferable that these two support surfaces, when the housings are in a position for hanging vertically, lie closely adjacent, are parallel and confront each other so as to give the impression that the receiver is a single housing construction. Similarly with the housings in the other relative positions other surfaces confront and lie parallel to each other also to give the single housing impression.
