Patent ID: 8422689

Claim:
A speaker system, comprising: a source encoder/decoder for receiving an audio signal, performing a first audio source processing program and an encoding/decoding process on the audio signal to output a first signal and a second signal, and performing a second audio source processing program to filter out the audio signal with a frequency larger than a predetermined frequency to output a third signal and a fourth signal according to an inputting parameter; a first main audio speaker unit and a second main audio speaker unit, for receiving the first signal and the second signal respectively; a first orientation speaker unit and a second orientation speaker unit, for receiving the third signal and the fourth signal respectively, the first and second orientation speaker units being high frequency speaker units; and first and second power amplifiers, wherein the third signal is transmitted to the first orientation speaker unit from the source encoder/decoder through the first power amplifier and the fourth signal is transmitted to the second orientation speaker unit from the source encoder/decoder through the second power amplifier.
