     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     With particular reference to the above figures, the sound-box device comprises a container 1 advantageously consisting of a first container portion and a second container portion which are adapted to be mutually associated by suitable sontainer portion connection means. The first container portion is advantageously constituted by a first half-shell 2 and the second container portion is advantageously constituted by a second half-shell 3 which are adapted to be mutually associated by suitable container portion connection means. Each of said half-shells 2, 3 defines a hemisphere, so that the container has an overall spherical shape in operative configuration. 
     The container 1 has a hole 1a through which an attachment or coupling string 50 of the device passes. 
     Each container portion may be comprised of a supporting frame portion and a related covering membrane portion which are both mutually attached by suitable coupling means. In the preferred embodiment shown in the figures, for example, the half-shells 2, 3 are advantageously constituted by a supporting frame made of significantly rigid material, in particular provided by molding in plastic material in the shape of hemispherical domes 4, 5. The domes 4, 5 of the supporting frame are externally covered by related membranes 6, 7 made of deformable plastic material which are adapted to act as covering. 
     The outer surface of the membranes 6, 7 conveniently has a grid with polygonal elements 8 drawn thereon; said elements partly enclose pentagonal portions 9 of a dark color, so as to give the container 1 the appearance of a soccer ball. A plurality of graphic symbols 10, such as for example flags of various national states, is furthermore defined on said surface. 
     The membranes 6, 7 are rigidly associated with the domes 4, 5 by means of conventional double-adhesive elements, not illustrated in the drawing, or by analogous coupling means. 
     The domes 4, 5 are joined to one another at their edges for a portion 11 adapted to act as a hinge. In a diametrically opposite position with respect to said hinge, the first dome 4 has a slot 12 which is adapted to be elastically engaged by a tooth 13 defined at the end of a tab 13a which extends from the corresponding edge of the second dome 5. The domes 4, 5 can be connected by any other suitable container portion connection means. A plurality of teeth 14 furthermore extends along the edge of the first dome 4; the thickness of said teeth is half that of the dome itself, and the teeth 14 are adapted to act as centering means in the coupling of the two domes 4, 5. 
     Arranged inside the container 1 there is an electronic control element 15 provided with a microprocessor which is per se known and is adapted to drive the device and produce a plurality of electric signals which can be transduced into sound signals ordered in a plurality of sound sequences. 
     The control element 15 is advantageously mounted on a base 16 arranged substantially at the connecting plane of the half-shells 2, 3. Said base 16 has a circular shape and peripherally rests on a plurality of shaped teeth 17 which are angularly distributed on the inner surface of the first dome 4. The base 16 is locked elastically along the outer edge by a plurality of engagement teeth 18 defined by the dome 4 at related notches 19; said base 16 is furthermore locked by a plurality of dowels 20 which protrude from the edge of the second dome 5. 
     It will be noted that the control element 5 can suitably be mounted upon any type of supporting means which are fixed to the inside of the container 1 by appropriate supporting locking means. 
     Electric power supply means advantageously constituted by a pair of electric batteries 21 for supplying power to the device, are intended to be provided inside the container 1 and can advantageously be mounted on the base 16. The batteries 21 can be accomodated in the seats defined by a support 22 which defines a pair of heads 23 joined by a partition 24 intended to separate said batteries. A respective pair of spring elements 25, 26, adapted to act as electric contacts for connection to the batteries 21, are associated on the heads 23 at notches 23a. 
     The batteries 21 are secured in their related seats, after the closure of the container 1, by a pair of partitions 27 defined inside the second dome 5 in a transverse direction with respect to said batteries; the partitions 27 are reinforced by longitudinal ridges 28. 
     Sound signal emission means advantageously constituted by a loudspeaker 29 for emitting the sound signals is accommodated in loudspeaker accommodation means inside the container, advantageously inside the first half-shell 2, and is arranged with its emission diaphragm 30 directed toward the inside of the container 1, in practice advantageously facing the base 16. Advantageously, the loudspeaker accommodation means are such that the loudspeaker 29 is centered on an annular ridge 31 defined on the internal surface of the dome 4, parallel to its edge, and is locked elastically by a plurality of engagement teeth 32 defined by said dome 4 at related notches 33. The loudspeaker 29 is connected to the control element 15 by means of a pair of electric wires 34. 
     Sensor means communicating with the electronic control element 15 for activating or selecting the electric signals transducible into sound signals are associated with the container 1 such that the sensor means are activated at the outside surface of the container 1. In the preferred embodiment shown in the figures, such sensor means are advantageously constituted by a plurality of sensor elements 35 applied on the outer surface of the domes 4, 5; said sensor elements are connected to the electronic control element 15 and are adapted to be actuated on corresponding graphic symbols 10 defined on the outer surface of the container 1 for selecting related sound sequences. The sensor elements 35 are constituted by a membrane keyboard formed by a plurality of contact switches 36 which are electrically connected in parallel to the electronic control element 15. The keyboard is provided by depositing conducting material on a pair of films 37 intended to be glued respectively on the domes 4, 5. 
     More precisely, the switches 36 are constituted by a circular external terminal 38 and by an internal terminal 39 which extend from respective conductors arranged so as to form a radial pattern on the film 37; the terminals 38, 39 of the switches 36 have respective branchings 38a, 39a which interpenetrate so as to facilitate the closure of the electric contact. Said contact is closed by contacting the switches 36 with respective graphite layers 40 applied on the internal surface of the membranes 6, 7 at respective graphic symbols 10. 
     The switches 36 are applied at respective flattened portions 41 defined on the outer surface of the domes 4, 5; said flattened portions 41 are distributed along substantially meridian lines, at which the surface of the dome has chamfers 41a of reduced width with respect to said flattened portions. Said flattened portions 41 therefore define an interspace between each switch 36 and the covering membrane 6, 7, so that the electric contacts are normally not closed. 
     The two halves of the keyboard are connected to the control element 15 by means of related loose strips 42, 43 of the films 37; said strips insert in the domes 4, 5 through respective slots 44, 45. The ends of the strips 42, 43 are retained, by means of opposite recesses 42a, 43a, on a pair of couplings 46. 
     Said couplings 46 have a tab 46a for the elastic securing of the strips 42, 43 and are adapted to be engaged, by means of a pair of teeth 46b, in holes 47 provided on the base 16. The heads 23 of the support 22 of the batteries 21 couple on the base 16 in a similar manner. 
     The couplings 46 are fixed on the face of the base 16 which is directed toward the first half-shell 2, i.e. on the side opposite to the batteries 21. A chamfer 48 is provided on the base 16 to allow the passage of the strip 43, which extends from the second half-shell 3, to the coupling region. The base 16 is furthermore provided with a recess 49 at the region where the tooth 13 couples to the slot 12. 
     The operation of the described device is easily understandable. By pressing the outer surface of the container 1 at one of the symbols 10 defined thereon, a corresponding sound sequence is emitted. The deformation of the covering membrane 6, 7 of the container in fact places the graphite layer 40 arranged below each symbol 10 in contact with the respective switch 36, closing the electric contact between the related terminals 38, 39. The branchings 38a, 39a of the terminals ensure the closure of the electric contact even in case of an imperfect pressing of the graphic symbols 10. 
     In a preferred embodiment of the device, the selectable sound sequences are constituted by the national anthems of a plurality of nations whose flags are correspondingly defined on the outer surface of the ball so as to constitute said symbols 10. In particular, the nations provided may be those which participate in sports championships and the like. 
     It is naturally possible to provide that said sound sequences reproduce musical tunes or sounds of different kinds, such as for example animal sounds, sounds of musical instruments, characteristic voices of celebrities and the like. 
     Different graphic symbols, such as for example pictures of animals, musical instruments, celebrities and the like, can be provided correspondingly on the outer surface of the container of the device. 
     The outer shape of the container of the device may equally be different from the one described. In particular, said container may have a generally rounded shape, such as that of a rugby-ball, or the shape of a polyhedron or of other similar geometrical solids. 
     To conclude, the device according to the invention allows to produce a plurality of sound patterns or musical tunes, matching their selection with appropriate graphic representations capable of easily recalling them. 
     The device has a very small size by virtue of the optimum arrangement of the components inside the container; it furthermore has no visible actuation elements. The device is conveniently provided with a string 50, inserted in the hole 1a of the container, which facilitates its transport for example hung from the wrist or neck. 
     The device is very easy to use, since it is sufficient to actuate the contact switches concealed below the covering to obtain the emission of the sound patterns or musical tunes. 
     The device can be easily opened to allow the insertion of the batteries. For this purpose it is sufficient to exert pressure on the edge of the second half-shell 3 at the tab 13a, so as to cause the disengagement of the tooth 13 from the slot 12 provided on the first half-shell 2. 
     In the practical embodiment of the invention, the materials employed, as well as the shape and dimensions, may be any according to the requirements.
