There is not much information on the breadboard image, what is the purpose of the circuit, what is the V value of the + ?
Be careful, some circuit found on the net simply does not work.
If you are looking to make an oscillator I might advise you to build an APC (Atari Punk Console), with two 555 (or one 556) and with a 9V battery.
But a speaker would be really necessary for all that, don’t you have an old headset, clock radio, car radio, … to recover a small speaker ?
