Abstract
A detachable earpiece auditory device comprises a housing, a speaker, and a connector. The housing has a sound outlet, a second opening, and a spring element positioned at the second opening. The speaker is provided within the housing and comprises an electrically conducting speaker terminal at an outer surface of the speaker. The connector comprises a first insert part, an electrically conducting connector terminal, and a second insert part. The first insert part is insertable into the second opening. The electrically conducting connector terminal is positioned in the first insert part to obtain electrical contact with the electrically conducting speaker terminal and forms a mating pair of a speaker terminal and a connector terminal when the first insert part is inserted into the second opening. The second insert part operatively contacts the spring element to bias the speaker terminal against the connector terminal with a predetermined bias force.
