The aspect that makes this instrument really singular is its working: it is played without being touched! It is made of two antennas, approaching or distancing the hand to the vertical antenna you can control the intonation, while with the horizontal antenna you can control the volume. The two antennas are fixed on a chassis, containing the electronic circuits, measuring 193 x 62 x 110 mm (7.6” x 2.45” x 4.35”), with two control knobs regulating the starting and the intonation.
O. 23. Magnetophon Geloso G256 that was called "Gelosino" for its small dimensions. It has only two valves (12AX7 and UL41) with a selenium redirector. It was created in around 1955 by the Geloso manufacturer, founded by John Geloso, born in 1901 in Argentina; his Piedmontese parents came back to Italy in 1904. This big Italian manufacturer, thanks to its quality and reliable radio receivers, recording devices, and amplifiers allowed us, throughout more than thirty years (about 1950 - 1970), to record songs, listen to the radio, to voice cinemas, clubs, squares, and churches. This model is the successor of the famous G255, from which it took the nice coloured button panel and the arrangement of the controls, other than the "roundish" look. It is an excellent tape recorder used for music recorders. It has, in the middle of the front, an EM80 valve, the magic eye tube used as an indication of record amplitude.
O. 24. Phonograph-radio device with record-stand and drinks cabinet, datable to around 1950.

O. 26. Valve wire recorder, American, made by Webster-Chicago, 228-1 model. This is a recorder (dictation machine) very in vogue in 1950s and for the recording it used a thin steel wire, precursor of the magnetic tape. It is supplied with alternating current, 120 Volts, 70 Watts; made in 1951. The device has its original Bakelite microphone, 4 controls in the front panel for the listening and the recording, a neon lamp for the level of recording and the regulation of volume/starting/turning off. On the top there is a lever for the starter of the wire and the rewind, as well as a timer for a maximum of 60 minutes; the reels were produced of 15, 30, or 60 minutes. The wire, moving for 62cm (24.4”) per second, was more than 2.5 km (15.55 mi) long, all in a reel that was wound and rewound also thanks to the vertical oscillation of the needle that allowed the right spooling. The wire is made of "ERGON" steel, and it was lightly oiled to preserve the needle and to guarantee the regularity for the movement of the wire.
O. 27. Singing bird, Swiss automaton made during the first decades of 20th century by Reuge manufacturer in Sainte-Crox. The history of mechanical music began in 14th century in Flanders, but only in 1780 the Jaquet-Droz brothers invented the singing bird. In 1848, The Parisian Bomtems Blaise invented the mechanism of singing birds that has remained almost the same until now. In 1865 Charles Reuge, clock maker from Val De Travers, moved to Sainte-Crox, town famous for the production of music boxes, and founded the production factory of singing birds that is still operating. This instrument is made of a cage with a red bird on a perch that turns around, moving the beak and the tail. The height of the cage is 311mm (12.25”) while the diameter of the base is 162mm (6.35”); the cage structure is made of silver, covered, at the bottom and near the hanger, with Capodimonte porcelain with figures and flowers on a silver background. The brand, stamped on the bottom, is: REUGE lyre MUSIC / SAINTE-CROX / MADE IN SWITZERLAND.
O. 28. Anonymous serinette, coming from Prague, datable to the second half of 19th century. The name comes from French “serin” (canary), because it was used by the girls of the time to teach the canaries to sing. This instrument is made of a wooden box (233 x 165 x 151 mm – 9.2” x 6.5” x 5.95”) with inside a little bellows, a worm drive that activates a nailed cylinder, and some levers that open the valves of the wind chest. The crank, on the front, activates both the bellows and the cylinder that opens the valves directing the air to the ten wooden pipes under the instrument that produce the sound. Near the pipes there is a title block with the list of the five musical pieces: U panského Dvora (ancient folk music: “At the landowner‘s farm house”), Proč bychom se netĕšili (“Let's rejoice and be merry”. A musical piece from Bedřich Smetana’s opera “The Bartered Bride”), Boleslav (a city in Central Bohemia), Nesluyde mládenci (“youth”), Neťukej, neťukej (ancient folk song: “Do not tap”). A brass lever on the right allows to lift the levers and move the cylinder to change song.
O. 29. Suitcase portable gramophone branded: LA VOCE DEL PADRONE / logo of the dog listening to the gramophone / Società Anonima Nazionale del “Grammofono” Milano. The name of the British company actually was Gramophone, but because of the famous Francis Barraud’s painting "His Master's Voice" (In Italian: “La voce del padrone”) depicting the dog Nipper listening to a gramophone, used as the brand of the label, it soon took this unofficial denomination. In 1931 SNG (Società Nazionale del Grammofono, founded in 1912 by Alfredo Bossi), SAIF (Società Anonima Italiana di Fonotopia) and Marconiphone (Italian manufacturer specialised in producing radio devices) joined to give birth to a single manufacturer that imported and distributed gramophones and was also a record industry. The measures of this model (HMV 102), made in England in around 1934, are: 285 x 410 x 150 mm (11.2” x 16.15” x 5.9”), the serial number is 2896. The charge is by crank and the speed can change around 78 rpm, it has an automatic brake and a turntable, the horn for the sound is under the turntable near the motor, while the case for the needles is on the front left corner.
O. 30. Pathé gramophone, Diffusor type, Lumière model, datable to the second decade of 20th century. At the end of 19th century the brothers Charles and Emile Pathé founded the Pathé Frères that, at the beginning, only imported from US Edison phonographs and Colombian gramophones, combined with cylinders registered in French. Then, in early 20th century, they started the production of their own gramophones, renamed Pathéphonès, that show many innovations: the needle made of «non-consumable» sapphire that, the advertisement explains, «has not to be changed after every hearing», guaranteeing at the same time a reproduction «without hoarse or nasal sounds, but a perfect voice ». The Pathéphonès, made in France, Belgium, Austria, and Russia, are different from other gramophones because the recording of the record starts from the centre and finishes outwards. Furthermore Pathé, for its records (produced in five sizes, up to 50 cm -19.7”- of diameter), adopts the recording system developed by Edison for the cylinders. The French brothers wanted to impose their technical standard, but they’re too smart to «forget» who had already bought gramophones from other brands: so the mechanical adapter was born, allowing to use the Pathé records with every device. The success was huge, also because the Pathéphonès were sold by instalments, with the system «Pay while listening to music »: in Italy the cheaper Pathéphonès, made of wood [«uso walnut»], cost 65L, while the model Duplex with two horns (or funnels, as they are defined on the catalogues) reaches the cost of 375L. This gramophone has the box made of wood with dimensions 360 x 450 x 138 mm (14.15” x 17.7” x 5.45”) that contains the perpetual mechanism charged by a crank, that makes the record turn constantly. The conical horn, made of cardboard, thought by the Lumière brothers in 1913, with parabolic shape, has diameter 358mm (14.1”) wide, in the centre of it there is the sapphire needle that «reads» the classic record. This gramophone can reproduce 78 rpm Pathé records measuring 29cm (11.4”) and 35cm (13.75”) and it is branded on the cardboard: DIFFUSOR PATHE’ / BTE S.G.D.E. while on the body there is the writing: Pathé.

O. 32. Portable barrel organ branded: COCCHI, BACIGALUPO & GRAFFIGNA / BERLIN. Schönhauser Allee 78, datable to the last decade of 20th century. Many talented Italian makers of mechanical organs made their fortune abroad: Gavioli went to France while Giovanni Battista Bacigalupo, in 1879, emigrated to Berlin and there he founded the first manufacturer with Chiaro Frati: the "Frati & Co." in 1 Buchholzer Street; in 1891 he founded, with the organ maker Giuseppe Antonio Cocchi and the restaurateur Graffigna, a new enterprise with the name “Cocchi, Bacigalupo & Graffigna". The manufacturer had its splendour during the 1920s and had up to fifty employees, and it produced instruments like the Meloton, the Harmonipan (Violinopan-organ), and the Tino Cornet organ. This instrument is equipped with a crank that, besides making the music roll turn, activates two bellows that, canalising the air to the reeds freed by the movement of the pallets, produce the sounds. The music roll can be arranged on seven positions corresponding to as many songs. The front is closed by a red rag that probably substitutes the original painted fabric. The songs listed on the inner plaque are not the same the can be really played, thus it is possible that the music roll has been substitute during the 1930s.
O. 33. Europhon radiolamp, designed by Adriano Rampoldi in 1968. The Europhon manufacturer was born in Milan during the postwar, proposing on the market several model of radio that were operational, economical, and with a captivating design. It became famous for the production of the first hybrid products (the radioclock, the radiotelevision, and the radiolamp, all designed by Adriano Rampoldi) but it later collapsed because of careless business choices. The radiolamp has three controls: two for the regulation of the light intensity (suffused or full light) and one to turn on the transistor radio.

O. 42. Reuge music box, mechanical, with manual charge (Volga) probably made in 1972. Box made of elm briar-root and cut glass, with 72-notes comb and cylinder with three tunes, short music pieces from 5th, 6th, and 9th Beethoven’s symphonies. A complete charge allows to reproduce about 16 times the tunes. Making the front button slide, the music box reproduces all the pieces, taking it back to the starting position the melody stops at the end of the piece. The mechanism is always visible. The reproduced tune is identified by a little marker that indicates the number of the tune with an arrow, and every tune lasts about 36 seconds. The dimensions are 230 x 145 x 100 mm (9.05” x 5.7” x 3.95”) and on the mechanism there is the serial number 18037. The manufacturer, in the heart of Jura Mountains, has been founded in 1865 by the clockmaker Charles Reuge and it remained a family business until 1988, when it was transformed in a limited company that today has about 60 co-workers. Antoine Favre is the father of the music box and the contemporary musical movements were based on a two-hundred-years-old idea: in 1796, the Genevan artisan substituted the existing spring and bells with vibrating teeth. The sounds are extremely more clear, more varied and precise. This innovation is the history of mechanical music. The knowledge of music box masters spread out thanks to clockmakers who left Sainte-Croix to work in Geneva. During the period of Napoleonic Wars, they went back to their native town, because of the lack of manpower and started to till the land, without abandoning their workshop labour. Thanks to this priceless know-how, Sainte-Croix region soon became the cradle of music box. At that time the town counted just barely three thousand inhabitants, but the authorities soon understood all the economic potential deriving from handmade production of mechanical music: at that elevation it is impossible to live only with the products of the soil. Founded in 1808, the Société d'Horlogerie of Sainte-Croix called back from the city the greatest clockmaker masters. While they divided their time between the agriculture on the mountains and the workshop labour, the inhabitants of the town took advantages from their precious teaching. The clocks and the music box they produced benefited in refinement and precision. In a few years, Sainte-Croix was able to compete with the great Maisons of Geneva.
O. 43. Music box machinery, second half of 20th century, made of metal. Comb with 18 notes playing the tune of Stille Nacht.
O. 44. Royal phonograph from Pathè Freres manufacturer, made in 1904. It is a sound reproducer made of a metal cylinder shaft activated by a spring charged by a crank on which a wax cylinder rotates. The needle of the reproducer courses on the groove recorded on the wax and transmits the sound to an amplifying horn. The cylinders used for this instrument, the Salons, were bigger than usual cylinders, with the diameter being 90mm (3.55”) and the height 106mm (4.15”). These dimensions permit a better quality of reproduction compared to Edison cylinders. The dimensions of the box are 24 x 16 x 12 mm (0.95” x 0.6” x 0.45”).

The rollers have a diameter of mm. 48 for 286 of width while the length of the paper depends on the duration of the piece. During a convention held in Buffalo in 1908, a standard was established that was subsequently adopted by almost all manufacturers. This standard includes all 88 piano notes. The first roll, created by George Barbiero in 1919, is marked L'ÉDITION MUSICALE PERFORÉE, shows the label: Célébre Sérénata / op. 6 / E. Toselli. The second, coeval, EMPECO (The Empeco system, popular in Europe but virtually unknown in America, was used by Philipps, Kastner and many other European manufacturers, some Empeco systems have been installed in coin-operated instruments for use in public places ), on the label: 3057 / Moment d'Amour / (Liebesaugemblick) / Valse Lente / von / Leo Eysoldt.
O. 59. Gramophone Pathé Concert with a crank action, built in Paris in 1910 by Pathé Frères. "Le Concert Automatique Français" was widely used in French public places before the First World War: the robust speaker, the oversized horn and a token device was ideal for spreading the sound in large, crowded rooms. For ten cents you could hear the latest songs of the time. After inserting the coin, the gramophone has a device that stops the motor after a precise number of rotations, corresponding to the average length of an incision. The instrument is equipped with a sapphire needle and plays records with a diameter up to cm. 50 which make the needle move from the inside to the outside. The powerful engine allows you to listen to several records in a row without having to load them every time. Characteristic is the door behind which it is possible to stack the records. The gramophone is impressive: it has a height of mm. 2120, the diameter of the black horn, is mm. 670, in front, under the engine, there is a sliding shutter that allows you to store the records, on the top floor, in addition to the rotating plate, there is the mechanism to change the rotation speed and the coin slot.
O. 60. Amplivoice amplified four-transistor trumpet, built in 1962 by Geloso in Milan. The realization of this megaphone stems from an idea of engineering. Edgardo Velicogna, technical director of Geloso until '69 and a very close collaborator of Ing. Geloso. The idea of making an amplified horn powered by six 1.5 Volt batteries and with a removable, directional microphone mounted on four legs was extraordinary. The success of Amplivoice (bulletin N ° 84 spring 1962) is immediate, it is an innovative product that was lacking on the market and is immediately used in many applications, such as street vendors, construction sites, sporting events, trade union events and various strikes. The trumpet molding is made of special plastic, practically indestructible, commercially called Moplen. The metal tag around the microphone printed: AMPLIVOICE / CAT N° 2583 – PAT PENDING, TROMBA AMPLIFICATA / CAT. N. 2583 BREVETTATO, SpA GELOSO / MILANO / MADE IN ITALY. The diameter of the trumpet is mm. 235, the total length of mm. 434 and a weight, without batteries, of Kg. 1.5. The emblematic image of the use of amplivoice, however, is that of Federico Fellini, who used the Geloso megaphone during the direction of many of his films.
O. 61. Projector with sound disc for children built in Barcelona in 1934 by the company NIC. In the 1930s, three brothers from Barcelona invented an instrument with which the little ones could, with just one crank, watch animated films printed on translucent paper bands and listen to the audio recorded on the related discs. Its operation is very simple and at the same time ingenious, conceived on the basis of the principles of the magic lantern: a paper ribbon with two slightly different images, above and below, are projected in such a way that a shutter alternated the vision of one and the other image (thus obtaining a precarious illusion of movement based only on two images that seemed alternating). The paper ribbon passes in front of the shutter, unrolling on one side and winding on the other. The optics are two simple lenses that show the bottom and top of the film, the point of focus should be sought by moving the projector away from the wall or screen where the images were seen. The lighting comes from a 40 Watt bulb. In 1932 the famous logo was patented: a black boy riding an elephant. The base of mm. 250 x 110 supports the projector, black, of mm. 223 x 112 x 80: on the right side there is the logo and the housing for the roller with the film while on the left side there is the cylinder cylinder on which the strip of paper is rolled and the crank of the gramophone to which it is hinged. On the upper floor is mounted the small gramophone consisting of the arm, the diaphragm with the chrome head and the plate, made of green felt with the inscription NIC / patentado, on which is screwed the disc in bakelite, 17 cm in diameter, related to the film. The instrument is accompanied by four discs with a story engraved on each side and the corresponding eight rolls of film.
O. 62. Portable gramophone with decomposable parts Excelda, built by Thorens of Basel in 1935. In the first decades of the twentieth century were made some gramophones with shape and size similar to cameras, so as to be coined the definition of "cameraphone", the gramophone Excelda is an example of this particular type, which was a great success, remaining in production from 1931 until the mid-'40s. The components are contained in a sheet metal box, craquelé blue in colour, with a screw-on lid on which there is a rich circular decoration and an oval plate with the inscription British Patent / N˚ 255001; the front and rear sides are rounded and one of them has a black leather handle with the inscription EXCELDA. Unscrewing the lid, inside the box there are the modular elements: a diaphragm with chromed head, a chromed arm and a crank with wooden handle.

O. 66. Electromagnetic bakelite speaker, the famous 2007 of 1928, known as "barber's plate" or "flying saucer". It is a brilliant example of industrial design: it was designed by Louis Kalff for Philips. The speaker has a cast iron triangular foot supporting a large concave platter with a convex inner disc. The motor and its paper cone are located inside the smaller disc while the larger parabolic disc is used as a reflector. A small rotary switch on the cable allows three different impedances: 500, 1500 and 200 ohms. This speaker was built in three different sizes (large: 2007, medium: 2003, small: 2015). The back of the outer concave platter is marked PHILIPS. The diameter of the larger disc is mm. 403, the overall height mm. 430, the thickness mm. 173 for a weight of gr. 3010. The colour is marbled brown and red with gold inclusions (in fact brass powder). The patterns were always different, as the colour ingredients were incorporated randomly so that each piece is unique. Louis Kalff was a pioneer of industrial design in the Netherlands during the first half of the 20th century: he studied furniture design, sculpture, ceramics and architecture and began working for Philips in 1924 in the marketing department for which he was later responsible. In 1929 he opened a lighting product design department and later became responsible for the lighting sections of the world exhibitions in Barcelona, Antwerp and Paris.

The perforated discs have a small metal plectrum at the hole, which excites the metal reed producing the sound as in ordinary music boxes. The mechanism is contained in a box measuring mm. 127 x 197 x 177 with the lid in walnut briar and the rest veneered in walnut, inside vie is the metal comb, the roller that transmits the impulse of the plectrums, the pin that rotates the disc and an axle that holds the disc in place. On the inside of the lid there is a paper print with dance scenes and on the outside there is the name Symphonion. The comb has forty metal reeds: a lever on the right side of the box allows to stretch the spring that will make the disc spin with a smaller lever on top that allows to stop the rotation. The Symphonion Company started business in 1885 and produced the first music box with a disc player. Its founders were Oscar Paul Lochmann and two partners Gustave Brachhausen and Paul Riessner. Within two years, however, these two men had left to found the Polyphon company which produced similar machines in competition with the original company. In 1889, the Symphonion company became a joint stock company or Aktiengesellschaft, with shares listed on the stock exchange. In 1900, Symphonion's business continued under the control of Franz Thumen and Hans Kanitz until 1909, when it ran into financial difficulties and was restructured, with the company name changing to Symphonion-Fabrik AG. Under this name it remained in existence at Schkeuditzer Strasse 13-17b in Gohlis. Symphonion is distinguished by the enormous diversity of types, styles and models produced.
