Audio signal

Ok, I have to synthetize an audio signal. I must do this by suming up the
harmonics of the sound.

So long I've got this:

function sinte(f)
  
  t=0:0.0001:0.0854;
  Fs = 44100;
  tau6 = 0.018;
  A6 = 25.1;
  f6 = f*7;
  x6 = A6*exp(-t/tau6).*sin(2*pi*f6*t/Fs);
  
  tau7 = 0.016;
  A7 = 15.8;
  f7 = f*8;
  x7 = A7*exp(-t/tau7).*sin(2*pi*f7*t/Fs);
  
  tau8 = 0.017;
  A8 = 19.9;
  f8 = f*9;
  x8 = A8*exp(-t/tau8).*sin(2*pi*f8*t/Fs);
  
  tau9 = 0.038;
  A9 = 12.5;
  f9 = f*10;
  x9 = A9*exp(-t/tau9).*sin(2*pi*f9*t/Fs);
  
  tau10 = 0.017;
  A10 = 10;
  f10 = f*11;
  x10 = A10*exp(-t/tau10).*sin(2*pi*f10*t/Fs);
  
  x = x6 + x7 + x8 + x9 + x9 + x10;

  wavwrite(x,Fs,16,"so.wav");
  
  endfunction


When I play the sound, I just hear a short 'puff'. 

The thing is that if I take away the '/Fs', It then sounds like a normal
'beep', which is what I want (I guess). Does anyone know what exactly does
the Fs mean?
