Abstract

The invention discloses a loudspeaker phonate hole draining apparatus and method and a mobile terminal. The apparatus comprises a detection module for sending a first frequency sweeping signal with a first preset frequency scope to a loudspeaker, so that the loudspeaker plays the first frequency sweeping signal. A microphone receives the sound played by the loudspeaker, and the physical characteristics of the loudspeaker are determined according to the sound. The apparatus further comprises a matching module for matching the physical characteristics with the preset physical characteristics, and a playing module for the loudspeaker to play a predetermined sound signal to drain water when the physical characteristics do not match with the preset physical characteristics. The loudspeaker plays a first frequency sweeping signal to detect the physical characteristics of the loudspeaker, and whether the water draining for a phonate hole is needed can be determined according to the physical characteristics change. When the water draining for a phonate hole is needed, the loudspeaker plays a predetermined sound signal to drain water. The operation process is easy and convenient.

Description

technical field

[0001] The invention relates to the communication field, in particular to a device and method for draining water from a sound outlet of a loudspeaker and a mobile terminal. Background technique

[0002] Since the mobile terminal will be in different use environments according to the different use scenarios of the user, therefore, performing waterproof treatment for the mobile terminal is an inevitable trend in the development of the mobile terminal.

[0003] For mobile terminals with waterproof characteristics, a semi-permeable membrane is generally added at the sound inlet of the Mic (microphone) and the sound outlet of the Speaker (speaker) to achieve waterproof intrusion without affecting the transmission of sound. But there is one thing that cannot be prevented. When the mobile terminal falls into the liquid and is picked up, the sound hole outside the semi-permeable membrane of the speaker will be filled with liquid, which will cause blockage and affect ...
