when the mobile equipment acquires that the hand-held call mode is switched to the hands-free call mode, the voice playing device on the mobile equipment is converted into a loudspeaker function from a receiver function, whether the voice playing device is blocked or not is monitored through a distance sensor of the mobile equipment,
if the voice playing device is monitored to be shielded, reducing the playing volume of the voice playing device under the function of a loudspeaker;
gradually restoring the playing volume of the voice playing device under the function of the loudspeaker.
10. A computer-readable storage medium having stored thereon computer-executable instructions, wherein execution of the computer-executable instructions by a processor causes the processor to perform operations comprising:
when the mobile equipment acquires that the hand-held call mode is switched to the hands-free call mode, the voice playing device on the mobile equipment is converted into a loudspeaker function from a receiver function, whether the voice playing device is blocked or not is monitored through a distance sensor of the mobile equipment,
if the voice playing device is monitored to be shielded, reducing the playing volume of the voice playing device under the function of a loudspeaker;
gradually restoring the playing volume of the voice playing device under the function of the loudspeaker.
