Phonograph needle of an acoustical phonograph rests on a slotted metal piece which acts to convey audio signals from the electromagnet headphone-type driver unit to the diaphragm of an acoustical tone arm, which in turn conveys sound to the standard phonograph flare horn. Pin plugs on the cord attached to the Dulce-Tone unit plug into the audio output stage of a radio receiver. Original sale price $10.00 Reference: Pettingell-Andrews Catalog No. 7 (1925-26), page 53. "[This unit is an] electroacoustical coupler, designed to connect the audio output stage of a radio receiver to a standard acoustical phonograph. They were advertised as cures for the 'unsightly' loudspeaker which generally had a horn shape at this time. Basically a magnetic headphone, coupling was achieved by inserting the pickup needle into a reed on the driver."
