The word "acoustic" is derived from the Greek word ἀκουστικός (akoustikos), meaning "of or for hearing, ready to hear" and that from ἀκουστός (akoustos), "heard, audible", which in turn derives from the verb ἀκούω(akouo), "I hear". The Latin synonym is "sonic", after which the term sonics used to be a synonym for acoustics and later a branch of acoustics. Frequencies above and below the audible range are called "ultrasonic" … WebbThese highly influential volumes, first published between 1877 and 1878, contain Rayleigh's classic account of acoustic theory.

Think of the membran of your loudspeaker as the guy pushing the swing. It's not a single air molecule but the whole mass of the air in our room that acts as a wobbling mass. The fact that the air will always try to be homogenously distributed in your room acts as spring.
