Patent number: 10045108Abstract: An earphone device is provided. The earphone device includes a pair of earphone modules. At least one of the earphone modules includes a microphone, a speaker, and a housing configured to accommodate the microphone and the speaker in an inner space thereof. The housing includes a path hole to allow the inner space to communicate outside of the housing to facilitate sound outside of the housing to enter the microphone or sound generated by the speaker to travel outside of the housing, and a partition element to partition the path hole of the housing into a first passageway and a second passageway, the first and second passageways being isolated from each other. The microphone or the speaker is housed inside the partition element. The speaker is spaced apart from the microphone at a predetermined interval and arranged to be side by side with the microphone.Type: GrantFiled: January 20, 2016Date of Patent: August 7, 2018Assignee: CRESYN CO., LTD.Inventors: Jong Bae Lee, Se Hong Oh
