the identifications of the target audio assembly outputting the audio signals in the current posture are determined from the first audio assembly, the second audio assembly, the third audio assembly and the fourth audio assembly; wherein the current posture includes: a folding posture or an unfolding posture.

Optionally, when in the unfolding posture, the first screen is in a display state, due to the fact that the first screen simultaneously covers the first middle frame and the second middle frame, the first audio assembly and the second audio assembly are mounted on the first middle frame, and the third audio assembly and the fourth audio assembly are mounted on the second middle frame. Therefore, the display area of the first screen simultaneously covers the four audio assemblies, and at the moment, the four audio assemblies may all serve as target audio assemblies.

Optionally, when in the folding posture, only the second screen may be in a display state, the second screen only covers the second middle frame, the third audio assembly and the fourth audio assembly are also mounted on the second middle frame, at the moment, only the third audio assembly and the fourth audio assembly are located in a coverage range of the second screen, and it may be determined that the third audio assembly and the fourth audio assembly are target audio assemblies. At the moment, the four audio assemblies may not need to serve as target audio assemblies, and power consumption is reduced.

It will be appreciated that when in the folding posture, in order to achieve a better audio playing effect, it may also be determined that the four audio assemblies are target audio assemblies.

Optionally, the step that the identifications of the target audio assembly outputting the audio signals in the current posture are determined from the first audio assembly, the second audio assembly, the third audio assembly and the fourth audio assembly includes:.

In practical application, when in a folding posture, the first screen is in a non-display state, at least one of the first audio assembly and the third audio assembly which are located at the top end of the terminal as well as at least one of the second audio assembly and the fourth audio assembly at the bottom end of the terminal may be selected as target audio assemblies to form stereo sound. The target audio assembly outputting the left channel audio signals and the target audio assembly outputting the right channel audio signals may be designated at will according to needs.

Optionally, the step that the output parameters of the output audio signals are determined according to the display state of the screen and the distribution positions of the first audio assembly, the second audio assembly, the third audio assembly and the fourth audio assembly in the terminal further includes:.

In practical application, when in a transverse screen state and a vertical screen state, the screen in a display state is different from the audio assembly aligned to the left hand of the user, by the mode of determining the target audio assemblies in the embodiment of the present disclosure, the degree of matching between the audio signals output by the target audio assembly and the state of the user in different display states is increased, and user experiences are improved.

Optionally, the step that the indication parameters of the target audio assembly are determined includes:.

Optionally, the orientation of the display area in the display state is defaulted as the direction in which the user is located. When the first screen is in a vertical screen display state or a transverse screen display state, four target audio assemblies are arranged, the target audio assembly located on the right side of the center line of the display area of the first screen (also referring to the side of the left hand of a user) outputs left channel audio signals, the target audio assembly located on the left side of the center line of the display area of the first screen (also referring to the side of the right hand of the user) outputs right channel audio signals; wherein the target audio assemblies include at least one of the first audio assembly, the second audio assembly, the third audio assembly and the fourth audio assembly. For example, when the first screen is in a vertical screen display state, the first audio assembly and the second audio assembly which are located on the left side of the center line of the display area of the first screen output right channel audio signals; and the third audio assembly and the fourth audio assembly which are located on the right side of the center line of the display area of the first screen output left channel audio signals.

Optionally, when the second screen is in a display state, two target audio assemblies are arranged, one of the two target audio assemblies outputs left channel audio signals while the other target audio assembly outputs right channel audio signals.
