Sound options for my Polar Express baggage car

That is why I suggested finding a speaker, not head phones 
But you can always add an amplifier to power the speaker you are going to use, if you go the headphone route.
I have seen some pretty small Bluetooth speakers before, but it has been a minute... And I have no idea if they'd fit into a N scale coach.
I want to say most Bluetooth headphones are around 1/2watt - 1 watt, and possibly 4ohms - 8ohms so they could work, but they maybe very quiet, it all really depends I suppose.
I did have a set of Motorola S9s that were pretty loud, you could hear them when they were in ear/covered what have you, and the battery life was like 6hrs talk time, and 4hr music....

So I found this 2w Bluetooth speaker, 1.05"X1.05"X 1.26", today at Walmart, let the dissection begin!

If the guts can be squeezed into a car, especially if there were some provision for charging off the tracks, that would open up some very interesting possibilities.

Hope that's just a typo!

Nope, @eric220 I plan to get the USB charging port to point out the bottom for a portable charger plug in.  Nothing will rely on track power. 

1. OEM Speaker is too big, glad I bought a Bachmann K4 speaker a while back, which fits perfectly inside the car Tested it attached onto the wires and it works.

2.  Battery will fit after some slight rearrangement of the power tabs and wires.

3.  Circuit board will be a tight fit.  Going to have to push part of it out the bottom refer to first comment. 

Yes @central.vermont thats a typo.

Pics later tonight.

USB uses 5 volts, so charger needs a 5V supply to charge the battery. If running on DCC a 5V power supply can be designed which could use track power and would be charging the batteries.

[eric220]

I didn't mean to imply that the system should rely on track power exclusively. It definitely needs a battery pack for reliability. I'm just thinking about my camera car. It has a battery that's good for several minutes. It charges off the track, so as long as the DCC system is powered up, the battery stays charged. It's a very convenient, hassle-free charging solution that provides practically indefinite power. Of course, having the USB plug accessible isn't exactly inconvenient, but it does mean that the sound system is only good as long as the battery stays charged.

In the end, just a thought. I'm not sure if adding the electronics to charge off the tracks would even be feasible. Either way, I'm looking forward to watching this build

@eric220 Well the build will be short! and don't worry, I didn't infer anything from your post!

Here is the unit playing some Bare Naked Ladies from my phone with the Bachmann speaker to replace the OEM 16mm one.

Here is the install with the roof removed.

And here is the car playing some Stevie Ray Vaughn with the roof installed.

Assuming you posted 3 videos in the last post, I no see um.    Just blank spaces in between the lines of text.

This is more appropriate!

Nice! I'm glad that worked out so well for you!
Now we just need to see a video of it on the tracks and moving.... With music that isn't copyrighted... That way it wont get taken down...

@nscaler711 that video isn't mine!  It was already on YT. My video is just my model playing what is already there!

[eric220]

Dang! Everything fits in there so nicely! How long does the battery last?

[Lemosteam]

@eric220 , it played through the entire install, about 2 hours, until I turned it off.
