Embodiment Construction

[0026]As shown in Figure 1, a rectangular film type sound carrier 4 has a thickness of about 0.2 to 0.3mm and is made of transparent plastic material, it has a spiral sound groove 5, and the sound groove 5 is suitable for being reproduced by sound A cyclic pickup search of the device, the sound reproduction device is adapted to be placed on the sound carrier 4 with positioning feet. The sound carrier, which can be glued to the pages of a book, has, for example, a cohesive adhesive coating on its back. The outline shows that the sound carrier 4 in FIG. 1 has two adjacent conventional annular adjustment holes 6 at the top of the figure and two other adjacent adjustment holes 8 at the bottom evenly distributed on the periphery. Adjacent switch-on protection elements 7 in the form of engraving and embossing can be arranged in a known manner between the lower adjustment openings. The upper adjustment hole 6 has only a circular structure with a diameter of 5 to 6 mm, while the lowe...

Abstract

A sound carrier (4) for a sound illustrated book having a spiral shaped sound groove and adjustment perforations arranged outside of the same. At least one, but preferably two, of the adjustment perforations (6) 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 are each surrounded by an upwardly protruding annular bead. As a result, it is necessary to monitor one or two adjustment perforations only when placing the sound reproducing device on the sound carrier. The view of adjustment perforations is not impeded by the front side of the sound reproducing device with the arrangement facing the user.

Description

technical field [0001] The present invention relates to sound carriers, particularly for books or other printed matter with audio instructions, the sound carrier being associated with selected pages of the book or the like. Background technique [0002] Film-type sound carriers can be inserted, bound or glued in books. As a separate sound carrier, it can also be attached to printed matter in a stable form. It can be designed double-sided and bound at the junction of the book. Such a sound carrier generally includes at least one spiral sound groove and at least two, in most cases, four adjustment holes, the adjustment holes are arranged on the outside around the sound groove area, arranged symmetrically with respect to its center line, and mostly It is in the form of a circular hole. The adjustment holes are sized so that each of them surrounds with a small clearance a positioning foot of the sound reproduction device placed in a pre-positioned position. The sound reprodu...
