Headphone Amplifier + Speaker Amplifier Project

[Muhaa]

Hi i was wondering if any one would able to point me in the right direction i know little about electronic components but
can solder and have a few bit's and bobs..

Im looking to make a attachment for my metal-detector that will include a speaker and its own amplifier and will become an attachment feature i have thought of adding blue-tooth module to this project and will all be boxed with and input and out put jack..

Here is what im working with i would like the best sound i can get really has to be good quality and be distinguishable against all the tones that the metal detector makes..

I have the schematics of the metal detector and also i was wondering if any one could point me in the right direction i had an old panasonic subwoofer i got ages ago and just used the speakers but the sub was driven by a built in amp so got me thinking..

I stripped it down as i wanted to see what parts i can salvage for my project i come across a 8 pin dip chip and also loads of resistors and diodes and other bits and pieces..

Im wanting to make it relatively small maybe 20cm long or 15cm roughly by about 5cm wide maybe a little more that is just a rough estimate looking at where i will be attaching it to the metal detector..

Depending what functions comes along with the "Panasonic RSN311W64 Module" this is what i was going to use for my main amplifier..

Is this even possible and if so could any one point me in the right direction i looking to use as much of the module as possible if it has tone features of any kind or anything really that will help in achieving a better quality sound than
my Metal Detector offers..

I have found a pin-out i think and some schematics that may be able to help im looking to run this as low as voltage as i can with maximum being 18v remote control car battery of some kind i see it takes a 14.7v input but im not sure about this..

Has any one a data sheet or some input in what im trying to achieve..

This is where i salvaged all my parts from so i can use any parts of this and also
buy any thing else i need..

And the specific RSN311W64B Pinout.

Im wanting to try and use the parts i have got to make it smaller and portable enough to fit the metal detector..Is this even possible using this "Panasonic RSN311W64 Module" there is also a 8pin dip micro controller that obviously drives some thing i also have a dip programmer but never used it.

Im not sure of the capabilities of this module so until i know that i wont know what functions i can add i know i need two speaker's built in a jack plug for head phones and jack plug of input from metal detector which will be done by "jack plugs"..

What are the capability of this module and what pins do what and also how much power is she going to need...

Thought it would be a fun thing to try out..

Thank you for any input and help ;-)

You can make an audio amplifier from easy to use IC's such as LM386 or TDA2002 or TDA 2003.

Only a few components need to be added.

Check power supply specs to make sure it can run from your metal detector supply.

To cut off the speakers automatically when you plug in headphones, there is the 3-conductor headphone jack with internal switching.

Hey thank you for the reply i understand what your saying about the chips you have mentioned i just wanted to do it
different and try to learn some thing new.

There is schematics all over the LM chips and could of done that without posting i just want to try learn some thing
new i will have a look into this module i have see whats its capable of..

If i don't get any further i will have no choice to go with the LM chip or the others you mentioned i will look
into these chips data sheets today..

I will be adding my own power supply to this,The power wont be taken from the metal detector.

Thank you for your time
