A charging adapter (10, 42, 52) and a mobile terminal (40,50) are disclosed. The charging adapter includes: a pneumatic pump (32), pneumatic cover (31), a sealing rubber gasket (33), a pneumatic valve (36), an air pressure monitor (34) for monitoring air pressure intensity in the pneumatic cover, and an air pressure controller (35) for controlling the pneumatic pump and the pneumatic valve to be turned on and off. The pneumatic pump, the air pressure monitor, the air pressure controller and the pneumatic valve are fixed at any location on a side surface of the pneumatic cover respectively. The sealing rubber gasket is disposed at a periphery of a front surface of the pneumatic cover. And the pneumatic cover is configured to tightly fit with a sound hole (41, 51) of a speaker SPK module of a mobile terminal through the sealing rubber gasket during charging, thereby forming a sealed cavity |
