At first glance can you tell what this object is?

Honestly if I saw this invention with no label, I wouldn't have a clue what it is. My first thought would be to look through what looks like an eyepiece. It looks like an object that you would look through and maybe twist the gold section in the middle to change the focus. The top two images show the same object and the third image shows an additional object which is connected to the top object. If I saw these two objects side by side, I might have a better idea of what it is used for. With the second part of the object I would, once again try and look into the section where he is clearly talking into. If sight is not its intention then I would try my other senses. Hearing is next so I would attempt talking into it which is what it's intended for.

As humans I think we are curious creatures and our method of figuring out what something is, is to test our senses on it. The first is sight, then maybe picking up and touching the object. Next we might use our voices to create sound and talk into it. I doubt we would smell it or lick it but you never know. Depends how curious you are.
