Connect audio wires to DFPlayer

[p3rs3f0n3]

Hi, I'm making a project using a DFPlayer with Arduino. DFPlayer only supports a speaker of 3W max connected to the SPK pins, but I need a louder volume , so I want to connect an amplified 8W speaker to the DAC_L and DAC_R pins of the DFPlayer. At first, I thought about using a PAM8610 amplifier connected to a speaker, but later I realized that I could simply use a pair of stereo PC speakers, which have already included an amplifier.

So, I'm trying to connect directly the PC speakers to the DAC_L and DAC_R pins of the DFPlayer. I've cut the jack connector of the speakers and I've found three little wires: a white one, a grey one and a green one. I've found a wiring diagram (attached to my post) to connect some headphones to the DFPlayer, and I see two wires connected to the DAC_L and DAC_R pins and a third wire connected to GND. I supposed I have to do the same connection with my amplified speakers, but I don't know which wire I have to connect to each pin. Could you help me with the colour of the three wires?

Thank you so much.

Your picture shows connections to a JACK. I don't know why you cut the jack off your speakers but just check which colour used to go to which connection on the original jack.

Thank you, I cut the jack off because I can't connect a jack to three pins.

So why not use a jack socket?
You can’t push these wires into a solderless bread board directly.

To find what wire is what measure the resistance between the wires. Find the wire that has the least resistance to the two others. That is the ground.

Then put the headphones on and measure the resistance between the ground and one of these wires. You will here a click in one of the phones. Depending on if it is left or right where you here the click you will know which is which.

Thank you for your answer. Sorry but I don't know how a jack socket works. Do you mean something like this? And how should I connect the socket's pins to the three pins of the DFPlayer? (the socket has 5 pins...).

[Grumpy_Mike]

Yes something like that.

You can get many different types, some are bread board friendly in that they have their pins with a 0.1 inch spacing. Like the one here. Here is a picture of two of them being used on some strip board for a project I did.

Thank you so much, Mike, but I still don't understand how to connect the 5 pins of the socket to the 3 pins of the DFPlayer.

Go to the link I posted. Click on the data sheet tab and download the data sheet. Here it will tell you what pins are connected to what.

That applies to any jack socket, or indeed any component you use in electronics. The data sheet has the answer.

[p3rs3f0n3]

Yes I know, and I checked the data sheet in your link, before (I promise). But it didn't solve my doubt, sorry.

[Grumpy_Mike]

So what is your problem?
Do you not understanding what that data sheet is telling you?

It says that pin 1 should be connected to ground, pin 2 connects to the ring ( left ) and pin 5 connects to the tip ( right ).

Buzz it out if you are unsure of the pinout. Multimeters have a continuity function for this purpose.
I'd recommend always buzzing out any connector or switch rather than have to hunt down the
right datasheet (often tricky to be sure you have the right one).

I was having same issue with a word solver playing and missing the audio, got help from this post and solved the issue. Really helped a lot.
