Abstract
An audio transmission apparatus has a primary speaker and a secondary speaker apparatus. Two primary speakers are provided to correspond with the left channel and the right channel. The secondary speaker apparatus is placed on a first surface of the primary speaker. A switching mechanism, such as a micro switch or a proximity sensor, is disposed between the primary speaker and the secondary speaker apparatus such that removal of the secondary speaker apparatus enables the secondary speaker apparatus and disables the primary speaker. Connected by wire or a wireless medium, the secondary speaker apparatus is an earphone, a head set, or an ear bud, depending on the application. The audio transmission apparatus is used in conjunction with any type of audio output device, such as a television, computer, stereo, and the like.
