    i will like to make a very simple transmitter receiver thing with only items below:

    wires
    Buzer
    batteries

    what my plan is to have something like wires with batteries and when theyre connected,the receiver which has a buzer will produce sound.

    maybe anyone can show me how and is it possible to only use these materials??

    Thnx,since im trying to understand wave transmission and receive thing

    Audioguru might help you with constructing a crystal radio and foam plate speaker, if you ask nicely.

    Without diodes and FETs/transistors, you will find it extremely difficult to detect, isolate and amplify radio signals. Good luck using only buzzers and batteries.
