The left channel audio signal is generally a signal of a bass frequency region, and the right channel audio signal is generally a signal of a treble frequency region.
When the sound generating device in the mobile terminal is a loudspeaker and comprises two sound generating devices, the first sound generating device is a top end loudspeaker, and the second sound generating device is a bottom end loudspeaker; or the first sound generating device is a left side loudspeaker, and the second sound generating device is a right side loudspeaker; alternatively, the first sound emitting device is a front speaker and the second sound emitting device is a rear speaker.

The top edge refers to the short side of the top of the mobile terminal and the bottom edge refers to the short side of the bottom of the mobile terminal. The first side and the second side of the mobile terminal refer to two long sides. The first side is a left side when the front of the mobile terminal faces upward (i.e., the side where the touch screen is located faces upward), and the second side is a right side when the front of the mobile terminal faces upward.
One attitude corresponds to a range of attitudes, for example, a landscape state in which the angle of the plane of the mobile terminal with respect to the ground is within an angle range (for example, 45 degrees to 90 degrees) in a manner such that the first-side-down landscape state includes a typical attitude in which the mobile terminal is perpendicular to the ground (i.e., the angle of the plane of the mobile terminal with respect to the ground is 90 degrees), and also includes an attitude in which the angle of the mobile terminal with respect to the ground is less than 90 degrees, for example, the angle of the mobile terminal with respect to the ground is 80 degrees, 70 degrees, or the like, within the range of attitudes.
The following is a detailed description by way of a few specific examples.
Example 1:
when the mobile terminal rotates from the horizontal screen state with the first side edge facing downwards to the horizontal screen state with the second side edge facing downwards, the sound channel signals played by the two sound generating devices are switched.
The initial posture of the mobile terminal is a landscape state in which the first side faces downward, the mobile terminal is perpendicular to the ground, or the mobile terminal and the ground form a certain angle (for example, an angle of 45 degrees, 60 degrees, 80 degrees, and the like) as shown in fig. 3, the initial posture of the mobile terminal is a landscape state in which the first side faces downward and the second side faces upward, and after the mobile terminal is rotated 180 degrees in a rotation direction indicated by an arrow shown in fig. 3, the mobile terminal is rotated to a landscape state in which the second side faces downward and the first side faces upward.
When the mobile terminal is in the initial posture, the top end loudspeaker plays the sound signal of the left sound channel, and the bottom end loudspeaker plays the sound signal of the right sound channel. The top speaker is oriented in the left direction and the bottom speaker is oriented in the right direction. After the mobile terminal is rotated 180 degrees in the manner shown in fig. 3, the mobile terminal is rotated to a new posture, the orientation of the top speaker is in the right direction, the orientation of the bottom speaker is in the left direction, the top speaker plays the right channel signal corresponding to the bottom speaker originally oriented in the right direction, and the top speaker plays the left channel signal corresponding to the top speaker originally oriented in the left direction. Therefore, the user can experience stereo sound effect corresponding to the viewing angle before and after rotation. If the mobile terminal is rotated as shown in fig. 3, the playing signals of the two speakers are not switched, and after the rotation, the audio effect heard by the user does not correspond to the positions of the left ear and the right ear of the user, so that the hearing experience of the user is poor.

Example 2:
when the mobile terminal rotates from the horizontal screen state with the second side edge facing downwards to the horizontal screen state with the first side edge facing downwards, the sound channel signals played by the two sound generating devices are switched.
In this example 2, the same operation as in example 1 was performed except that the rotation direction was changed.
As shown in fig. 4, the initial posture of the mobile terminal is that the horizontal screen state with the second side facing down and the first side facing up is rotated 180 degrees, and then the mobile terminal is rotated to the horizontal screen state with the first side facing down and the second side facing up, and after the channel switching condition is met, the channel playing switching is performed.
The angle of rotation of the mobile terminal in the initial pose shown in fig. 4 may be an angle in a range from a first angle to a second angle, where the first angle is smaller than 180 degrees, and the second angle is larger than 180 degrees, for example: the first angle is 170 degrees and the second angle is 190 degrees; the first angle is 160 degrees, the second angle is 200 degrees, and the like, and the channel switching condition is satisfied after rotating by an angle within the range.
