  • Earphone
    Patent number: 8059854
    Abstract: An earphone includes a housing, a reel mechanism, a speaker, and a transmission wire. The reel mechanism is pivotally disposed in the housing and has an accommodating space defined therein for accommodating the speaker. The transmission wire is wound on the reel mechanism. When the transmission wire is pulled or released and thereby drives the reel mechanism to rotate, the speaker rotates coaxially together with the reel mechanism.
