Mikiphone
A Mikiphone ( Vadasz system) is a pocket-sized gramophone from which the type designation Pocket Phonograph , in German pocket gramophone , also known as pocket record player , is derived. Those devices, developed by the Vadasz brothers from Hungary , are considered to be the smallest of their kind in the world that were able to play shellac records.
history
The development of the microphone began with the Hungarian brothers Nicolas and Etienne Vadasz, who began to construct a pocket gramophone around 1917 and, after completing the development work, achieved the patenting of the small device in 1924.
After a partner was found in Paillard & Cie from Sainte-Croix in Switzerland to start series production, the Mikiphone went on sale after 1925. Since problems with sales came to light, monthly production was cut back considerably and, after sales of 180,000 pocket turntables, it was discontinued in 1927.
The round casing of the Mikiphone made of sheet steel had a diameter of 11.5 cm and a height of 5 cm when closed and a weight of 1.2 kg. The sound box membrane consisted of mica coupled to a sound resonator made of Bakelite .
