What increases at the speaker with the increase of loudless-intensity?

[luckis11]

Surely, its maximum displacement A increases.

But what about its speed? Increases, decreases, remains the same?

And what about the number of the vibrations of its maximum displacement per sec? They increase or decrease or remain the same? This number is the frequency of the music f, or not?

Please post only those who are certain of the answer, or certain of what today's physics claim on this.

 

[AJ Bentley]

The number of vibrations per second is the musical note.

The loudness is determined by the amplitude (size) of the movement.

So, if you want something to move further in the same amount of time, you have to move it faster.

It ain't Physics - it's just plain common sense.
