    Is there a way to wire a npn transistor using a speaker and a function generator. I'm trying to get my power supply to provide the power and the function generator to provide a 1 khz tone. I'm just doing this to better understand how to use transistors. Any help is appreciated thanks.

    Googling "one transistor amplifier" will get you lots of circuits to look at.

    Or read our resource and this one.
    The first one tells you how to use an NPN trransistor as a switch. Replace the load (motor) in th eexamples by the speaker et voilá.
    Or dive a bit deeper into the theory with the second resource.
