It allows one to play 45 rpm records, which have a big hole in the middle, on the turntable most people had at home which was designed for 33 ⅓ rpm records, which have a small hole. The shape forms a gentle spring to create tension inside the 45.
Just to add to this, many 45s came with the same small hole as LPs and 12" singles. The big hole was there for 45s that were to be used in jukeboxes, I think.
Most record players have an adjustable speed and can do 33.3 or 45 rpm and some can do the old 78s. There were also other speeds but they were mostly used for other applications. Otherwise yes, it would sound slow compared to an LP.

Does the audio just sound slowed down or is there something else
The different playback speed also allows more music to be squeezed onto each side of the disc (albeit at a slightly lower quality).
