Phonograph

A phonograph was an Earth device used in the nineteenth and twentieth centuries for the purpose of playing sound recordings, particularly musical compositions.

In an alternate timeline, Jonathan Archer and Alicia Travers listened to "My Old Flame", a song performed by singer Billie Holiday, playing on a phonograph. Since the Nazi occupation of the United States outlawed the playing of black music, the phonograph was moved to different dwellings throughout the building so as to disguise its exact location.
