Pocket Phonograph, Palliard Cie (St Croix), Circa 1926
This mikiphone has an approximate manufacture date of circa 1926. It is stamped in the interior with the maker’s mark of Palliard Cie (St Croix), who partnered with the patent owners, Nicolas and Etienne Vadasz for the large scale production of the mikiphones. A Mikiphone – or Pocket Phonograph is one of the earliest versions of a portable music player. The Mikiphone was small enough to fit into a pocket for portability, and once unpacked had the ability to play 10” records. Power was supplied to the unit by a small hand crank, and sound was amplified by a small resonator. It is estimated that 100,000 to 180,000 of the units were made between 1924 and 1927. Luxury editions were also available with either a gold or silver casing. Le Corbusier is quoted as saying he could ‘see in the Mikiphone the essence of Esprit Nouveau’. The pocket gramophone is significant for historical and social reasons. It is primarily an enabler of leisure activities due to its portability and size. The design of the object is also significant as it showcases design advancements in the early part of the 20th century. The Swiss made "Mikiphone", the smallest talking machine ever placed on the market folded up to the size of a large pocket watch or small cheese case. Production stopped in 1927. A total of 180,000 were made. A few were made in a luxury version with gold or silver case for a "Pretentious clientele".Inside on dial: Mikiphone / Pocket Phonograph / Swiss made / System Vadasz.
