Alternatively, then structural representation shown in Figure 1, microphone 11 can also comprise the first sound effect processing circuit 114, the second sound effect processing circuit 115, the 3rd sound effect processing circuit 116.The first sound effect processing circuit 114 is connected between sound collection circuit 111 and audio frequency combiner circuit 113, the second sound effect processing circuit 115 is connected between ANTENN AUDIO receiving circuit 112 and mixting circuit 113, and the 3rd sound effect processing circuit 116 is connected between audio frequency combiner circuit 113 and audio output circuit 117.The first sound effect processing circuit 114 is for carrying out audio processing to the first audio signal; The second sound effect processing circuit 115 is for carrying out audio processing to the second audio signal; The 3rd sound effect processing circuit 116 is for carrying out audio processing to the 3rd audio signal.
As shown in Figure 2, for the workflow schematic diagram of audio transmission system shown in Fig. 1 in the utility model audio transmission system embodiment, can comprise the steps:
Step 21, sound collection circuit 111 gather external voice, output the first audio signal, execution step 23;
Step 22, ANTENN AUDIO receiving circuit 112 receive the second audio signal that electronic equipment sends, execution step 24;
Wherein, electronic equipment can be computer, TV or portable electric appts, for example: notebook, mobile phone, panel computer, mp3 etc.; Alternatively, electronic equipment can, by Software Create accompaniment musics such as " singing ", then send to microphone by accompaniment music by wireless mode;
Step 23,114 pairs of the first audio signals of the first sound effect processing circuit are carried out audio processing, execution step 25;
Step 24,115 pairs of the second audio signals of the second sound effect processing circuit are carried out audio processing, execution step 25;
Step 25,113 pairs of the first audio signals of audio frequency combiner circuit and the second audio signal are synthesized processing, output the 3rd audio signal, execution step 26;
Step 26,116 pairs of the 3rd audio signals of the 3rd sound effect processing circuit are carried out audio processing, execution step 27;
Step 27, audio output circuit 117 output the 3rd audio signals, execution step 28;
Step 28, audio reception device 12 receive the 3rd audio signal.
Wherein, step 23, step 24 and step 26 are optional step.
Alternatively, the 3rd audio signal that audio reception device 12 receives can be play by audio-frequence player device 13.Alternatively, audio-frequence player device 13 can for audio amplifier, television set etc. can playing audio signal equipment.Alternatively, between audio reception device 12 and audio-frequence player device 13, can be wireless connections or wired connection; Or audio reception device 12 can synthesize in an equipment with audio-frequence player device 13.
In the present embodiment, after synthesizing, launches by wireless approach the voice signal that the audio signal that microphone 11 sends electronic equipment and microphone 11 gather, then the signal that audio reception device 12 receives after synthesizing, through audio-frequence player device 13, play, user can hum by microphone 11 melody that and then electronic equipment sends, and the melody of electronic equipment and user's sound is synthesized together, thereby in the situation that there is no Specialty Hi-Fi equipment, also can realize people's voice signal and music signal are synthesized.
Alternatively, in the present embodiment, in order to reduce costs, simplified design, can only include one or two in the first sound effect processing circuit 114, the second sound effect processing circuit 115 and the 3rd sound effect processing circuit 116, for example: only include the first sound effect processing circuit 114 and/or the second sound effect processing circuit 115, or only include the 3rd sound effect processing circuit 116.
