Surely if I use a speaker I can get the background music route back from mic. but there will be a very bad audio quality as i guess...
So I want  to use the headset and the mic, then there will be no music echo after I record the "mic" and "speaker" together.

Just in case it is skype there is the skype-call-recorder which capture your call and even separate it into output and input.

But how can I mix the mic and speaker together?
I want to use "~/.asoundrc" or "amixer" or something like that...

My use case is just add a backgroud music to my voice record.

Thanks for you suggestion for JACK.

But can i use "~/.asoundrc" or "amixer" to realize it?

I have never used jack myself I am afraid. I just know that it is what is
often suggested for doing the kind of mixing you are refering to. Again, it
would seem that you could always add in the background music afterwards (or
even if your system is playing the music it will come in through the
microphone with your voice anyway.)

Why can you not "mix" them
afterwards, since the stuff going out your speaker surely originated from
your
computer anyway.

Huh ? How about recording a VOIP session - the stuff going to speaker
originates in somebody else's computer.


Uh, no. It goes through your computer.  But at least you have given me a
clue
as to what he might be refering to. (Ie, using it to record skype phone
calls
he is making).


One possibility is to use jack to link up the pieces. There have also been
discussions in the past as to how to record stuff leaving
the machine.
