<p><P>PROBLEM TO BE SOLVED: To provide an audio reproducing device capable of simplifying the constitution of the device. <P>SOLUTION: An amplifier unit is equipped with: a synchronization transfer packet receiving section 433 for receiving main voice data; a PLL circuit 424, etc., for producing a clock signal synchronized with the main voice data; a synchronization transfer packet receiving section 434 for receiving sub-voice data ; an FIFO 421 for main voice wherein the main voice data are stored and read out in synchronization with the clock signal produced by the PLL circuit; an FIFO 426 for sub-voice wherein the sub-voice data are stored and read out in synchronization with the clock signal produced by the PLL circuit; a read-out timing control section 428 for monitoring the data amount before the sub-voice data stored in the FIFO for sub-voice are read out, and instructing a start of read-out when the data amount reaches a predetermined amount; and a voice processing section 429 for reproducing the main voice data and sub-voice data by synthesizing them after being read out. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
