This invention relates to sound-reproducing' apparatus and hasfor its ob ect to provide an "apparatus adapted to operate either as a phonographic sound reproduclng 5 machine or as a receiver of wireless signals.

According to the invention the sound reproducing machine is so provlded that a Wireless receiver amplifying devlce may be substituted for the sound box or'for the sound box and the member carrying it 1n Order that'the horn on sound amplifier of *speaker.' 1

According to the inventlon, moreover, n

.,In-,the constructionrepresented in Figure 2,, the panel- I) carrying the elements comprising the wireless recelvmg set is disarPQSed in the lower part of the cabinet behind-the doors 7;. which usually cover a com 7 partment adapted to, hold records. The panel is conveniently .carried within a drawer i conformed to slide into and out of the cabinet as a drawer in order that the .c is conveniently received into a recess or various elements may be rendered accessible. The panel may, however, be secured in position by screws, clips or other fastening devices. The souiid amplifying devicec as before is adapted to be substituted in position for the sound box d. The batteries are conveniently enclosed within-the cabinet to the rear of the panel 6 and in the drawer 2', or they may be renderedaccessible'by a door iprovided iii-the rear of the-cabinet.

Similarly, in the case of sound repr'oducing apparatus having a cabinet of horizontal V rectangular form, divided by a transverse partition into twocompartments, the sound i reproducing apparatus is disposed 111 the one compartment and the panel carrying the wirelcssreceiviiig set in theother com- 1 partment, the lower portion of which may The panel may conveniently be 'c'overedwhen the wireless serve to receive records.

set is not in use, by a sliding or revolving u enim. a u.

According tothe-modified construction representedin Figure 3, the panel 6 18 mounted in a casing y serving to receive the elements of the wireless receiving set fitted upona board 70 which serves to close the cover or lid a or to form a bottom thereto and is hinged both to the cover or lid a and to the cabinet. When the'cover or lid 6; is closed upon the board 70, the casing j gagedwith the board-7c,- Thus, when the -board in are lifted together to expose the turntable'and tone arm, 'while when=the wireless receiving set is required, the board 70 and lidor cover w are first lifted together topermit the wireless sound amplifying de vice 0 to be substituted for thesound box d and the boardh is then lowered again and the cover or lid a disengaged from the retaining devices Z so that it may be raised to expose the panel I).

, It will be understood that theinvention is not limited to the details of construction hereinbefore described. Thus, the elements 'of the wireless receiving set may be provided as separate units not assembled on a 'panel but disposed within a'su-itable compartment or compartments formed in the lid or other containing casiiig; A frame aerial may be provided wound upon or in the lid or cover orupoii a frame fixedly secured to the cabinet, or the frame may be it mounted upon the cabinet that when required for use it may be readily elevated;

or turned into an operative position.

the cabinet at the inner end of the internal horn or sound amplifier and the wirless sound amplifying device be provided for reception into the said socket and to be secured therein.

v The wireless sound amplifying device in the construction represented in Figure 3 may be provided vitliiii a suitable casing fitted to the under-side of the board hand be adapted, when the board 71: is in position for the use of the,1wire1ess receiving set, to engage with a socket orv other connection fitted upon theinternal horn or sound amplifier of thelmachine. The said horn may for this purpose be provided with a branch or: may be forked so that one bra chser ves for connection to the tone arm and the other for connection with the sound amplifying device ofthe wireless set. a 7

It will be iunderstood that the inventio is not limited to any, particular construction of sound reproducing machine or wireless receiving set.- Moreover, the latter may if desirable be provided as a set-capable also of transmission.
