Abstract
The present disclosure provided a speaker monomer with a pair of dynamic speakers thereof includes a housing, an electro-acoustic conversion member received in the housing, and a PCB. The electro-acoustic conversion member includes a first dynamic speaker and a second dynamic speaker, and the housing is a double-barrel-shaped configuration and includes a first receiving room for receiving the first dynamic speaker therein, and a second receiving room arranged in parallel and separated from the first receiving room for receiving the second dynamic speaker therein. The PCB is installed in an end portion of the housing and electrically connected to the first and second dynamic speakers. The present disclosure not only can improve sound quality of an ear-in earphone, but also can reduce a volume of the ear-in earphone, improve assembly efficiency and reduce a defective rate of the ear-in earphone.
