Abstract:
1. An audio earphone system having a single earpiece with a single earpiece speaker adapted to be electronically connected to either a sound system audio jack of a stereo sound device or a sound system audio jack of a monaural sound device, the audio earphone system comprising: said single earpiece speaker having only one acoustical driver which is electronically connected and terminated in a three conductor audio plug, said three conductor audio plug adapted to be inserted into said audio jack of either said stereo sound device or said monaural sound device, resistors electrically coupled to different conductors in said audio plug, said resistors summing left and right channel stereo sound signals from said stereo system audio jack and monaural sound from said monaural system audio jack, said resistors having values which maintain an impedance match between said one acoustical driver and the coupled audio system, and said resistors delivering a summed signal into the one acoustic driver of said single earpiece speaker.
