Abstract: A sound carrier for a sound illustrated book having a spiral shaped sound groove and adjustment perforations arranged outside of the same and symmetrical with its center axis. At least one, but preferably two, of the adjustment perforations are designed in a circular form such that they surround with small clearance aligning feet of a sound reproducing device placed upon the sound carrier which has a rotating sound pickup, whereas other adjacent and opposite adjustment perforations in an upper side of the sound carrier are each surrounded by an upwardly protruding annular bead. This allows at first one or two aligning feet to be inserted into the adjustment perforations, whereupon the sound reproducing device is pivoted so that the two other aligning feet engage the two round adjustment perforations. As a result, it is necessary to monitor one or two adjustment perforations only when placing the sound reproducing device on the sound carrier.
