as others have said, to connect to some terminals. The speaker is there (i presume) to add extra clicking

The keyboard is an IBM 3151 terminal keyboard. The purpose of the speaker is to let the user know that the character has been registered successfully by the terminal, presumably for diagnostic purposes. Back in the days when IBM made truly manly keyboards, they used a solenoid that whacked off the metal casing when the key was pressed. Those were the days.

Adaption options are either the variety of terminal adapters off Geekhack (usually based around a Teensy adapter that costs ~$16), or swapping the controller from a donor Model M. I don't think Unicomp sells suitable controllers for those things any more.

This might be of interest if you want to adapt it to USB.
