(Step S36). Further, the song file F1 in the receiving mobile device 121 is played in the order of the playing queue (step S38), whereby the music signal S2 is generated, and then the tone adjustment is performed on the music signal S2. (Step S40) [0030] wherein the user 2 mainly performs the on-demanding of the song file F1 by the issuance of the selection command C1, whereby the receiving mobile device 122 arranges the song files to be ordered according to the order of the in-demand. The playback terminal device 111 receives the vocal signal S1 sent by the user 2 (step S42), and performs echo processing through the transmission extension device 112 (step S4). 4) Finally, after the end of the echo processing, the vocal signal S1 is transmitted to the receiving vocal device 12. More specifically, the vocal signal S1 is transmitted to the receiving extension device 122. [0032] The receiving The end expansion device 122 simultaneously receives the music signal S2 and the vocal signal S1 to perform a mixing operation (step S46). Finally, the sound after the completion of the mixing and the corresponding image are respectively output (step S48). The image system is output synchronously with the music signal S2, and is mainly a picture and a lyric corresponding to the song file F1 being played. [0033] Next, the receiving mobile device 122 continues to determine whether the song file F1 is 099137894, form number A0101, page 10, page 24, 0992066044-0 201220297, stops playing (step S50), and if not, returns to step S42. And if so, the play queue is updated (step S52). The playlist is mainly a to-be-listed list of the song file F1 that has been requested to be played, so when one of the song files F1 is played, or all the song commands C2 issued by the transmitting terminal accompaniment device 11 are received ( When it is as shown in the second figure, playback is stopped. Then, the song title or code of the song file F1 is deleted from the playlist, and the updated playlist is transmitted back to the mobile terminal device 111 to make the user 2 aware. [0034] It is worth mentioning that the song list U corresponds to all the song files F1 stored in the receiving mobile device 12 2, and the player 2 cannot order the songs not listed in the song list L1. [0035] Referring to FIG. 4A and FIG. 4B, a song transmission flowchart and a song downloading flowchart according to a specific embodiment of the present invention are shown. If the song to be clicked by the user 2 does not exist in the song list L1, an additional song file F2 can be transmitted to the receiving mobile device 121 by the transmission terminal device 111 (step S60). The mobile terminal device 121 receives the additional song file F2 and stores it (step S62), and updates the song list L1 (step S64). Finally, the updated song list L1 is re-updated. It is transmitted to the transmission side mobile device 111 (step S66). As a result, the user 2 will be able to order the additional song file F2 stored in the mobile device 111. [0036] As shown in FIG. 24B, the user 2 can also issue a download command C3 (as shown in the second figure) to the receiving mobile device 099137894^1 through the application 5 (step S70). . Therefore, the receiving mobile device 121 connects to the Internet according to the download command C3, and downloads a corresponding external song file form editor A0101 page 11 / page 24 0992066044-0 201220297 case F3 (step S72). Next, the song list L1 is updated (step S74). Finally, the updated song list L1 is retransmitted to the transmitting mobile device 111 (step S76). In this way, the user 2 will be able to order the external song file F3 not stored in the transmitting mobile device 111 and the receiving mobile device 121. [0037] In the present invention, the sing-along device 11 of the transmission terminal can perform the singing at the same time, so that the plurality of the vocal signals S1 can be simultaneously transmitted, that is, the transmission end expansion device 112 and the receiving end are expanded. Device 122 is implemented in the form of radio frequency transmission.
