A while ago, my family used to have a toy dog that jumped around and barked, etc. when you clapped. When the gears messed up, my father took it apart, and took the circuitry up and gave it to me when I was young to play with. When I would clap, it would activate a motor, and stop it again when I clapped once more.

Unfortunately, all the components became separated at one point and now I have them all, but they're not connected, and I don't know how to connected.

There is a motor, a battery source (1 C size battery), a microphone, and a circuit board.

The circuit has four unique points for connections to the other components. With 6 wires (two from each component) to be connected, I realize that some of them must be combined.

Can you guys give me an indication to how this should be reconnected? Which devices would likely be connected together (ie. battery connects motor which connects to circuit board which connects back to battery), etc. As well, which component would be likely to be connected to a capacitor, resistor, etc. as soon as enters the circuit board, etc.

I hope my description is help and good enough to understand. I tried searching for the numbers on the board on the internet, but found nothing.

Your help is appreciated!

 

Below is my best guess. Others might have better ideas, or even information. If you can post a picture of the circuit board, it might help.
The problem with the diagram below is that you may not be able to tell which way to connect the battery. Connecting it backward may damage parts on the board. Look for clues like polarized capacitor polarity, + or -, pos or neg etched on the board. If any wires remain, red is generally positive, black negative.
The "amplifier and flipflop" triangle will probably be made up of several components. If it is an IC, the transistor may be integrated into it.

Hmm, take a look at the attached pictures. I hope they help.

This is the above sematic of the panel. Cannot identify the output layout because of shadow.Hope this help.

Thanks for taking the time to label the photo.

To be honest, I'm not quite sure what to do with the schematic. The photo of the bottom of the board had a nasty shadow, but I used Paint to fix it up a bit.

 

Try discover the output stage and the Q4 type.
Make a better quality picture of bottom.
