1. An acoustic module waterproof protection mechanism, comprising:
an acoustic module provided in a housing;
an acoustic port provided on an outer wall of the housing and communicated with the acoustic module; and
a waterproof sound-permeable membrane provided on an inner wall of the housing and covering the acoustic port,
wherein the acoustic module waterproof protection mechanism further includes a waterproof valve assembly embedded in a wall of the acoustic port in a stretchable manner, and the waterproof valve assembly is used to stretch into the acoustic port to block the acoustic port when an external water pressure is greater than an air pressure in the housing,
wherein the waterproof valve assembly comprises a valve cavity provided in the wall of the acoustic port and a piston rod provided in the valve cavity in a stretchable manner, and
wherein a rod cavity of the valve cavity communicates with an inside of the housing, and a rod-less cavity of the valve cavity communicates with an outside of the housing.
