This invention relates to supports and particularly to those used for devices which are required to assume any one of a plurality of positions with respect to the user, such, for example, as earphone supports.
The object of this invention is to provide a supyport for a sound receiver which is inexpensive, rugged anddurable and which allows the receiver to be maintained in any one of a number of posiillustrated in Figs. 2 and 3. For example, if it is desired to have the receiver in its normal vertical position with respect to the user, groove I4 and the corresponding groove I4 in the opposite surface are used. If, however, it is desired to tilt the receiver in either direction with respect to the head-band, then slots I 5 and I5 or I6 and I6 are used. Fig. 2 shows the position of receiver I when grooves I6 and I6 are used.

This is accomplished by engagan extension on the receiver cooperating with a ing .diagonally Opposed grooves as, for example, slot in a depending portion of a head-band.
