12v MP3 Sound Module

[Biomecanoid]

Hello,

 

I want an MP3 sound module with an sd-card slot and onboard speaker that would play a music file ( only once ) when you 1st apply power to it and if you keep the power on after the music file is done it will not do anything else.

 

Something similar to this :

Anybody knows where i can find one ?

 

Thank you

What is its purpose ? What sort of volume ? mono or stereo ? Does it have to be mp3, wav is more common, why does it need to stay powered on ?

use a relay or transistor to trigger it

or

there are loads of modules about

Ideally it should have a speaker on its PCB, just a simple mono will do and loud enough to be able to be heard in the car. I don't mind if its not mp3 any sound file will do.

What i am trying to do is add a chime to the car that goes on when you turn the key and switch on the Battery.

I plan to tap 12v  power from a fuse. So the sound module will turn on with the car and will stay on until you power the car down so that's why i said the sound should play on ONCE and not be continuous, the sound should repeat only if you power cycle the car.

I have already found the module you showed me on eBay but that works on 5v which means i should add another hardware to convert 12v down to 5v which will make things a bit more complicated and more things can fail. The second link seems to be a module specific for Arduino.

If this little project is successful i will use the same technique to power and install a Dashcam.
