Keith,

  You could do this with a 556 and about half a dozen parts..

  half of the 556 gnerates the tone, and the other pulses it.

I am currently studying for my GCSE electronics and was wondering if any
ofyou cold think of a chip which  could produce a pulsing tone (like when
lorries reverse) without to much external circitry as it needs to be quite
small.
Thanks
Keith
