How to turn on small 3.5v motor using a Pyro electric sensor

Hi, sorry its been a long time, but the ciruit did not work

I have a block diagram of a possible circuit, could you draw me a diagram like last time how i would be able to connect it please

the images show a older version of the circuit, the only changes i have made is that that the sensor has been replaced by a passive pyroelectric one, and the relay is connected to two outputs, a mp3 connected by a PCB mounted stereo jack, which is connected to another one PCB mounted stereo jack, that is connected to speakers.

thanks
