20090022342 | DIGITAL DECODER BOX WITH MULTI-CHANNEL AUDIO SOURCE FORMAT INDENTIFICATION FUNCTION - A digital decoder box is introduced for processing multiple-channel digital audio sources. The digital decoder box can detect formats of audio sources and perform different decoding processes, and output the audio sources to an earphone with 5.1 channel speakers. When a 5.1 channel audio source is received, the digital decoder box decodes the audio source and outputs the audio source to the 5.1-channel earphone. Three sets of audio signals are outputs including front stereo signals, rear stereo signals, center channel signal, and sub woofer signal. When a two channel audio source is received, the amplified audio signals from the digital decoder box are output to at least two sets of speakers within the 5.1-channel earphone. By the various speaker combinations within the 5.1-channel earphone, sound effects of separated sound fields may be generated. A two channel stereo audio source may then have different sound effects. | 01-22-2009 |
