US 2017/0374467 A1 · AUDIO APPARATUS AND AUDIO OUTPUT PORT

Abstract

An audio apparatus includes an analog module that receives a digital left (L) channel signal and a digital right (R) channel signal and outputs first and second analog L signals and first and second analog R signals, a first output port that includes first to fifth conductors, through which the first and second analog L signals, the first and second analog R signals, and a ground voltage are provided, and a second output port that includes sixth to ninth conductors, through which the first and second analog L signals and the first and second analog R signals are provided. When an audio jack including first to third terminals is inserted into the first output port, the first and second conductors are connected to the first terminal, the third and fourth conductors are connected to the second terminal, and the fifth conductor is connected to the third terminal.
