Yep, sorta.
I wanna hear the sound come out of my best phono, my VE8-35x with it's 9 foot long folded up exponential horn.
Now that I think about the sound level that comes out of a reproducer just by itself, I'd guess the closest thing would be a tweeter with aluminum foil cone.
Hoping it would not filter out bass frequencies.
Thinking also that I could just form some jb-weld to hold a tweeter airtight in place.
If I formed up enough jb-weld, I could fasion a cone to the tone arm. Make a solid airtight grip on the tweeter speaker and pull it off the tone arm before it sticks solid.
Maybe a small plastic funnel could help.

I have done what you describe above, and enjoy demonstrating it for friends. I use an old transistor radio with an earphone jack, and connect it to one of the many types of radio adaptors that were made in the 1920s. I have several of the adaptors, but the one I enjoy most is the Dulce-Tone. This is the one that does not require you to remove the sound box - it works by vibrating the needle.
You can not connect the adaptor directly to the radio. You need to get a small audio transformer from an old 1930s vintage radio and build a simple box with the transformer inside and the in-and-out connectors. A radio collector friend helped me with this, and building the interface is a 30 minute job.
It works very well, especially on an Orthophonic. The adaptors appear on ebay regularly, and my friend sold me the transformer for a couple of bucks.
