    Looking for help with this sound generator toy

    Hello,

    This is a part to a kid's play kitchen setup that I picked up recently at a yard sale. I'd really like to get this working for my son. After putting in new button cell batteries, all I can seem to get out of the circuit is a faint clicking sound upon pressing the buttons/contacts.

    I'm not sure what kind of sound it's supposed to produce, but the circuit looks fairly simple, unless there is an IC I'm missing. I've checked voltage at about 4.8 coming out of the battery box, and going to the speaker/transducer. Thanks much for any ideas on this!

    It is one of those embedded IC DIE right on the PCB. i think all you can do is to check the surrounding components but not much you can check on the IC (IC IDE is under that black blob of epoxy).

      Thanks Bud. Do you think it's likely the IC has failed? Not sure on the surrounding components or how to test in circuit.

        about all you can do is test that lone transistor.it drives the speaker.
