ABSTRACT:
A portable stereo audio apparatus consists of a pair of speaker cabinets each containing a loudspeaker and a main cabinet containing electric devices such as amplifiers and a radio receiver. The speaker cabinets and the main cabinet are in the form of rectangular boxes. The speaker cabinets have half the width of the main cabinet and are normally set on the main cabinet. The speaker cabinets are hinged at their lower outer edge to each upper outer edge of the main cabinet so that when the audio apparatus is used as a stereophonic system the speaker cabinets are rotated about the hinges and located at both side of the main cabinet. The speaker cabinets have the edge diagonally opposite the lower outer edge, i.e., the upper inner edge, so formed as to provide gripping means when the speaker cabinets are rotated about the hinges and located on top of the main cabinet that enable the apparatus to be gripped by one hand and toted about.
