Patent ID: 8731227

Claim:
A tiltable earphone having an ear cushion mounted on the body of the earphone to be tilted freely with respect to the body, the tiltable earphone characterized in that: the body includes an outer case enclosing a sound wave generating means, and a ball joint which is provided at an end portion of the outer case having a sound wave path that propagates the sound wave generated from the sound wave generating means out of the body and has an opening communicated with the sound wave path; an operation holder is mounted on the outer circumference of the ball joint, wherein the operation holder includes a frictional ball seat in which at least a portion of the inner surface comes into contact with the outer circumference of the ball joint so as to combine therewith, an internal passage which is communicated with the inner space of the frictional ball seat to be opened to the outside, and a periphery for the ear cushion to come into contact from the outside, the ball joint and the frictional ball seat being movably interconnected along three degrees of freedom between the outer case and the operation holder; an air hole for air circulating is formed in the outer case corresponding to the opposite side of the sound wave path with respect to the sound wave generating means; and the outside of the outer case is provided with a both end open type cylindrical shaped vibration cover installed by blocking so that the air circulating through the air hole collides therewith, wherein a fixed end of the vibration cover is fixed to the body and a vibration end of the vibration cover is separated from the body, the sound wave path is configured to propagate the sound wave toward an external auditory canal of a user, while a vibration wave for generating airflow through the air hole propagates away from external auditory canal, and vibration is generated by collision of the vibration wave onto the vibration cover which obstructs the vibration wave, and the vibration is transmitted to the body.
