Amplifier substitute PAM8403 class D amplifier

[SarahG]

Hi, I am a newbie to electronic circuits and had the over ambitious task of making these bone conducing headphones from a tutorial online.
Here is a link to the project.
http://techiesms.com/misc-projects/3-projects-using-bone-conduction/
The project asks for a PAM8493 class D amplifier and specifies the circuit diagram for that. When I went to my electronics store they did not have the above mentioned but gave me this Arduino Compatible 2 x 3W Amplifier Module.
Here is the link.

My question is, can someone please send me a circuit diagram for the substitute amplifier that I have purchased. I am quite lost and the person at the store wasn't too helpful.

It would be very much appreciated

You were given exactly what you asked for. That part uses the PAM8403.

Connect it up exactly the same way.

I think those piezo transducers will sound awful.

The video shows people using a phone (no low audio frequencies and no high audio frequencies) with bone conduction but the type of transducer is unknown.

Here is the horrible frequency response of a Name Brand piezo transducer:
