Sound transmission laser

[Prospects]

I have built a circuit found often on the net to transmit sound via a laser pointer.Every part of the circuit works including photo cell receptor,amp and speaker,but the signal is not going through the laser pointer. Any suggestions would be appreciated.

You will need to provide a lot more information regarding exactly what is in your numbered boxes. For example, does the laser pointer include a constant current or constant voltage control circuit? What are the transformer characteristics? What input signal level does your amp need?....... etc
