Patent ID: 7471803

Claim:
Electro acoustic equipment comprising a loudspeaker for the reproduction of low frequencies ( 2 ), two satellites ( 6 ), an audio mixer ( 8 ) and a power unit, characterised by the fact that it is composed of: a main case ( 1 ) that has a front space ( 1 a ) having the same height as the case ( 1 ), which partially houses the speaker ( 2 ) and closed by a suitable box-shaped cover ( 3 ) with a grid ( 4 ) that hides an opening ( 3 a ) through which the speaker ( 2 ) is inserted and fixed, while the back of the case ( 1 ) has a lower space ( 10 ) used to house a power unit with heat dissipator (D), together with a pair of identical intermediate spaces ( 5 ) that exactly house the two satellites ( 6 ); a panel ( 9 ) with an upper wing ( 9 a ) basically folded at 90° inwards, designed to be mounted in stable position on the back of the case ( 1 ), in order to close the two spaces ( 5 ) for the satellites ( 6 ) and embrace the first rear section of the upper housing ( 7 ) for the audio mixer ( 8 ); a boxed-type removable cover ( 13 ), hinged to the lateral borders ( 7 a ) of the space ( 7 ) for the audio mixer ( 8 ), capable of oscillating from the horizontal stop position, when it perfectly closes the space ( 7 ), to a vertical stop position, in which it is flush with the back wall of the case ( 1 ) and used as handle to pull the equipment of the invention, thanks to the presence of a notch-handle ( 14 ) near the free horizontal edge; a pair of wheels ( 12 ) fixed inside two small vertical housings ( 11 ) with pins with horizontal axis, which are located on the bottom and back of the case ( 1 ), in lateral position with respect to the space ( 10 ) for the power unit; an electrical cable (CE), housed in the front space ( 1 a ) of the case ( 1 ), used to make the electrical connection between the audio mixer ( 8 ) contained in the upper space ( 7 ) and the power unit housed in the lower space ( 10 ).
