Abstract

Provided are a voice call method, an apparatus, a terminal, and a storage medium, relating to the technical field of the terminal. The method includes: obtaining, in response to a voice call instruction, a display screen state of the flexible display screen, the display screen state comprising at least one of a roll-up state and a spread-out state; controlling, in response to the flexible display screen being in the roll-up state, the flexible display screen to spread out, wherein the first housing and the second housing move relative to each other while spreading out the flexible display screen, and wherein a distance between the sound receiving hole and a sound source after the spreading out is smaller than a distance between the sound receiving hole and the sound source before the spreading out; and collecting call voice through the radio microphone.

First claim

What is claimed is:

1 . A voice call method, applied in a terminal having a flexible display screen, the terminal comprising a first housing and a second housing slidably connected to the first housing, the flexible display screen having an exposed display area that is changeable through a relative movement between the second housing and the first housing, and the second housing having a radio microphone;
the method comprising:
obtaining, in response to a voice call instruction, a display screen state of the flexible display screen, the display screen state comprising at least one of a roll-up state and a spread-out state;
controlling, in response to the voice call instruction and the flexible display screen being in the roll-up state, the flexible display screen to spread out, wherein the first housing and the second housing move relative to each other while spreading out the flexible display screen, and wherein a distance between the radio microphone and a sound source after the spreading out of the flexible display screen is smaller than a distance between the radio microphone and the sound source before the spreading out of the flexible display screen; and
collecting call voice through the radio microphone with the flexible display screen remaining in the spread-out state during the voice call.

2 . The method according to claim 1 , wherein said controlling, in response to the voice call instruction and the flexible display screen being in the roll-up state, the flexible display screen to spread out comprises:
in response to the voice call instruction and the flexible display screen being in the roll-up state, determining whether a current call posture is a predetermined call posture, the predetermined call posture being a posture during a voice call conducted through a receiver and the radio microphone; and in response to that the current call posture is the predetermined call posture, controlling the flexible display screen to spread out.

3 . The method according to claim 2 , wherein said determining whether the current call posture is the predetermined call posture comprises:
obtaining a current call mode and a sensor value outputted by a distance sensor, the distance sensor being located on a same side as the receiver; and determining, in response to that the current call mode is neither a hands-free mode nor an earphone mode, and in response to that the sensor value is smaller than a threshold, that the current call posture is the predetermined call posture.

4 . The method according to claim 1 , wherein said controlling the flexible display screen to spread out comprises:
determining a spread-out distance of the flexible display screen; generating, based on the spread-out distance, a spreading out instruction; and transmitting the spreading out instruction to a screen mechanical assembly, the screen mechanical assembly being configured to control, based on the spreading out instruction, the flexible display screen to spread out.

5 . The method according to claim 4 , wherein said determining the spread-out distance of the flexible display screen comprises:
obtaining a current screen length of the flexible display screen in the roll-up state, wherein the current screen length is a length of the exposed display area in a direction of the relative movement of the first and second housings; and determining, based on the current screen length and a target screen length, the spread-out distance, wherein the target screen length is a maximum spread-out length of the flexible display screen in the direction of the relative movement of the housings, or a self-adaptive screen length smaller than or equal to the maximum spread-out length.

6 . The method according to claim 5 , wherein the target screen length is the self-adaptive screen length; and
wherein said controlling the flexible display screen to spread out further comprises:
controlling the flexible display screen to spread out from the current screen length to the maximum spread-out length;
obtaining a loudness of the call voice collected by the radio microphone during the spreading out; and
determining, as the self-adaptive screen length, a spread-out length corresponding to a maximum loudness.

7 . The method according to claim 5 , wherein the target screen length is the self-adaptive screen length; and
wherein said controlling the flexible display screen to spread out further comprises:
obtaining a facial image of a user; and
determining the self-adaptive screen length based on a distance between a mouth and an ear in the facial image of the user.

8 . The method according to claim 5 , wherein:
the first housing has a noise reduction microphone; the target screen length is the self-adaptive screen length; and the method, subsequent to said collecting the call voice through the radio microphone, further comprises:
determining, in response to spreading out to the self-adaptive screen length, a microphone spacing distance between the noise reduction microphone and a sound receiving hole;
adjusting, based on the microphone spacing distance, a noise reduction algorithm; and
performing, based on the adjusted noise reduction algorithm, a noise reduction processing on the call voice through ambient sound collected by the noise reduction microphone.

9 . The method according to claim 1 , further comprising, subsequent to said collecting the call voice through the radio microphone:
controlling, in response to an end-of-call instruction, the flexible display screen to roll up, wherein the flexible display screen is in the roll-up state after the rolling up.

10 . The method according to claim 9 , wherein said controlling, in response to the end-of-call instruction, the flexible display screen to roll up comprises:
obtaining, in response to the end-of-call instruction, a terminal gripping posture; and controlling, in response to an automatic spreading out or rolling up being allowable under the terminal gripping posture, the flexible display screen to roll up.

11 . A terminal, comprising:
a first housing; a second housing slidably connected to the first housing, the second housing having a radio microphone; a flexible display screen having an exposed display area, the exposed display area being changeable through a relative movement between the second housing and the first housing; a processor; and a memory having at least one instruction stored thereon, wherein the at least one instruction is executable by the processor to implement operations comprising:
obtaining, in response to a voice call instruction, a display screen state of the flexible display screen, the display screen state comprising at least one of a roll-up state and a spread-out state;
controlling, in response to the voice call instruction and the flexible display screen being in the roll-up state, the flexible display screen to spread out, wherein the first housing and the second housing move relative to each other while spreading out the flexible display screen, and wherein a distance between the radio microphone and a sound source after the spreading out of the flexible display screen is smaller than a distance between the radio microphone and the sound source before the spreading out of the flexible display screen; and
collecting call voice through the radio microphone with the flexible display screen remaining in the spread-out state during the voice call.

12 . The terminal according to claim 11 , wherein the second housing has a sound receiving hole, the radio microphone being disposed in the sound receiving hole.

13 . The terminal according to claim 11 , wher
