That circuit won’t make any sound as it is drawn. Please add a collector load resistor. You’re talking about it, why not just add it to to the diagram?

Why do you even post something this? This isn’t even an amplifier. It’s just random components. Firstly, the input stage seems to be an emitter follower. This won’t help you at all. You want to amplify voltage, not current here. The rest of the circuit is wired incorrectly. You have the bases wired to ground and the signal comes in on the emitter. What’s that supposed to achieve? The base will never go higher than the emitter and you will have zero signal out. There’s no way you built or even simulated this.
