In the early 1920s, several miniature folding gramophones were introduced to the British market. These devices were housed in small rectangular cases, resembling contemporary box cameras—a similarity that earned them the same nickname. Interestingly, this term was also tied to the fact that the original concept was purchased from the inventor by a British company bearing the same name.

To maintain their unique compact size, these gramophones lacked a traditional horn for sound projection. Instead, engineers sought to enhance audio quality through innovative experiments with different types of pickups and sound conduits. In the case of our model, this effort is embodied by an "egg" made of artificial tortoiseshell.

While the sound quality might not have been outstanding, these gramophones stand today as a testament to human ingenuity—proof that inventiveness thrives wherever opportunity presents itself.
