ABSTRACT:
A stereo headphone has a generally "U"-shaped head band provided with a pair of head band support rails at opposite ends thereof. End portions of the head band are received for sliding extension and retraction withing the support rails. A speaker support frame is secured to each of the support rails. A conventional speaker is mounted within each of the support frames. A pair of mounting bars are connected to each of the speaker support frames. An adjustable linkage allows compound adjustment of the mounting bars with respect to the support frames. A vibrational audio output disc is provided on an end portion of each of the mounting bars. A switch on each of the support frames allows selective actuation of each of the speakers. In use, the speakers of the headphones are received over the ears of a user in a conventional fashion. The vibrational audio output discs are then positioned by virtue of the compound adjustment linkage adjacent the temples of the user. This secondary vibrational audio output provides an enhanced listening effect.
