Abstract

The invention provides a sound source signal compound control device which is used for selecting the source of a plurality of sound source signals for outputting to a sound output device. The sound source signal compound control device comprises a universal serial bus input end used for receiving a first sound source signal, a portable music carrier sound source digital signal input end used for receiving a second sound source signal; a sound source signal output end used for outputting a sound source signal to the output device; and a switching unit used for selecting one of the first sound source signal and the second sound source signal and outputting to the sound source signal output end. The sound source signal compound control device can solve the problem that the traditional iPod docking can not be simultaneously used as an iPod and a sound playing device of a PC.

Description

technical field [0001] The present invention relates to a sound source signal compound control device, which is a sound source signal compound control device for selecting sources of multiple sound source signals to output to a sound output device. Background technique [0002] iPod Docking is a speaker that can be connected to a Walkman iPod and play the music in the iPod. It also includes a USB connection device connected to the personal computer, which can be used as a bridge between the iPod and the PC, and the music in the iPod can be controlled through the PC. access, and at the same time, it also has the function of charging the iPod with USB. [0003] see figure 1 , figure 1 It is a general connection diagram between iPod docking and iPod and PC, wherein iPod docking connection system 1 includes iPod 11, iPod docking 12 and PC 13, wherein iPod docking 12 includes a line in terminal 121 connected to iPod 11 for receiving the audio signal of iPod, Play through the l...
