Hey guys, So im having a few issues with my first Project.

Basically i found this old and obscure child's toy drum machine (a few drum loops and a couple of songs as well)

Everything was going superb and i was just about to put it into a project box until i got cocky and decided to simplify the way the circuit is powered. And for the most part i think i did a fantastic job until i came down to the speaker....

The speaker had 2 volume levels connected to the ON/OFF switch. when i tried to hook up the speaker in the original way it had been before i took apart the circuit, it didnt work.
So i fiddled around and found that if i soldered it to these 2 connections i could get it to work, although it is barely audible. it sort of sounds like i've hooked it into a spot where it has too much resistance against it.

Also i can get a few loud crackles when i play around looking for other ways to connect it. And the speaker is and was in perfect working condition.

So what im asking is if anyone has any ideas on how to find a way to hook up the speaker properly?

Here are a few pictures i took!

I'm not an expert but since no one else has replied here's what comes to my mind:

1. your 3-state switch is hooked up wrong and what you think is hi volume is actually lo volume?
2. you're using the wrong thickness of wire to connect the speaker?
3. you're using a different speaker than the original one that requires greater power?

i hope you haven't tried these yet. otherwise, just wait for someone who knows more than me to get here.

2. Thickness of wire plays no role here .

I can't see it properly, but it looks like the power switch is just a single pole on/off type.
Weren't those three black wires connected to a seperate switch ?

oh, can you explain when the thickness of the wire matters and when it doesn't? i don't think i understand that.

also i think he said that the on/off switch was a 3-state that also controls volume, or did i misunderstand something?

also a little bird just reminded me that there is a chance that the speaker's amplifier may have burned out if there was a short during the process of removing the speaker, or if it was operated while the speaker was disconnected. cheap toys probably don't have well-protected amplifiers.

Is it possible that the original 3 point switch perhaps combined the 2 on states to make the volume louder (compounding connections when you go from Med -> Loud) and you are only connecting one or the wrong one of the two?
