There is no empty space inside the modern phone. Packed with electronics and batteries.I've never really torn down a modern phone but wonder if it would be possible to get better LF response out of a common phone by driving the screen and back with a bipolar voice coil. If it could be better enough to warrant the difficulty in rearranging everything..

Yuk.
The only time i listen to music on the phone it is as a source.

The best way to do this is... a blue tooth speaker.... or an external DAC with built in battery, an USB-OTG cable and earbuds.
There is NO room inside a modern smart phone. None.
If you could 3D a deeper back shell, then you might be able to mount something there to give you a bit more.... "bass"...

It's never going to be hifi, and the lack of internal volume would be consequential, and if it helped at all it'd probably take too much power. But I think the magnet assembly could be used to help divide the moving mass equally front and plastic back, so only one coil needed. Also the entire screen assembly would have to be bonded solid for it to work, which I don't think is how it is usually done. Too many problems and just a curiosity.
The screen speaker has been attempted on televisions before. The cellphone display shoudn't be very different from that.

I heard that TV in 1999. Never caught on.

Tozzi is not a great enclosure. Why they started giving them away.
dave
Yeah, but they fit for their intended purpose. I need a center channel to build around two pairs of Acoustic Energies in a 5 channel surround. I plan on using both Tozzi's as center channel.

Sony had a flat screen not so long ago... it was a neat trick, I almost bought it but as any Sony "XBR" it was quite pricey.
