1. A mobile device, comprising:
a sound detection unit, detecting an environment sound around the mobile device and converting the environment sound to an external sound signal;
a signal processing unit, analyzing the external sound signal and determining whether to enable a sound mixed mode or a playing mode according to an analyzed result;
a sound mixing unit, mixing a music signal with the external sound signal in the sound mixed mode to generate a sound mixed signal; and
a speaker, wherein the mobile device plays the sound mixed signal through the speaker in the sound mixed mode,
wherein when the signal processing unit determines to enable the sound mixed mode according to the analyzed result, the sound mixing unit uses a plurality of weighted values to adjust the music signal and the external sound signal, and to generate the sound mixed signal,
wherein when the signal processing unit determines to enable the playing mode according to the analyzed result in the sound mixed mode, the signal processing unit generates a plurality of gain values, the sound mixing unit uses the gain values to adjust the music signal, and the mobile device plays the adjusted music signal through the speaker.
