Beschreibung
Zusammenfassung:	The invention provides a portable electronic device, a sound processing device and a sound processing method. The sound source processing device can output at least one audio signal generated by an audio decoder through at least one first loudspeaker and one second loudspeaker. The sound source processing device comprises a mixer and at least one filter, wherein the at least one filter allows signals at frequencies greater than a first given frequency in the audio signals to be output by the first loudspeaker and signals at frequencies smaller than the first given frequency in the audio signals to be first transmitted to the mixer and then output by the second loudspeaker. The method can improve the audio performance of the sound source processing device or the portable electronic device.
