The display device 100 includes a display screen 110 and a frame covering the periphery of the display screen, where the frame includes a first frame and a second frame that are arranged oppositely, and a third frame and a fourth frame that are arranged oppositely, in this embodiment, the first to fourth frames may be an upper frame 121, a lower frame 122, a left frame 123 and a right frame 124, respectively, and the first to fourth frames may be spliced with each other or integrally formed.
As shown in fig. 3, a first speaker 131 and a second speaker 132 are respectively disposed at the left end and the right end of the upper frame 121, a third speaker 133 and a fourth speaker 134 are respectively disposed at the left end and the right end of the lower frame, and preferably, the first speaker 131 and the second speaker 132 are disposed at the top of the upper frame 121, that is, the first speaker 131 and the second speaker 132 face upward; the third speaker 133 and the fourth speaker 134 are disposed at the bottom of the lower frame 122, that is, the third speaker 133 and the fourth speaker 134 face downward.
As shown in fig. 4, the display device 100 further includes an angle sensor 140 and an audio processor 150, and specifically, the audio processor 150 includes a control unit 151, a memory 152, an audio output circuit 153, a left channel audio input circuit 154, and a right channel audio input circuit 155. The audio processor 150 is a DSP microprocessor chip.
The output end of the angle sensor 140 is connected to the input end of the control unit 151, and the output end of the control unit 151 is connected to the audio output circuit 153.
The audio output circuit 153 is connected to a memory 152, the memory 152 is respectively connected to the left channel audio input circuit 154 and the right channel audio input circuit 155, the memory 152 receives the left and right channel audio signals generated by the audio generating device, buffers the left and right channel audio signals, and respectively outputs the left and right channel audio signals to the audio output circuit 153, and the audio output circuit 153 respectively outputs the left and right channel audio signals to the first to fourth speakers through the first to fourth power amplifiers 161 and 164.

For the mercury switch, the angle information is a switching value signal sent when the mercury switch is horizontal or vertical, and for the six-axis sensor, the angle information is a specific angle numerical value.
When the angle information detected by the angle sensor 140 indicates that the display device 100 is in the vertical display state, that is, the upper frame 121 is located on the left side of the display screen 110 as shown in fig. 3, the control unit 151 drives the audio output circuit 153 to output the left channel audio signal buffered in the memory 152 to the first speaker 131 and the second speaker 132, and the control unit 151 further drives the audio output circuit 153 to output the right channel audio signal buffered in the memory 152 to the third speaker 133 and the fourth speaker 134. Thereby, the played sound has a stereo effect when the display device 100 is in the vertical display state.
When the angle information detected by the angle sensor 140 indicates that the display device 100 is in the horizontal display state, that is, the upper frame 121 is located on the upper side of the display screen 110 as shown in fig. 5, the control unit 151 drives the audio output circuit 153 to output the left channel audio signal buffered in the memory 152 to the first speaker 131 and the third speaker 133 currently located on the opposite left side, and the control unit 151 further drives the audio output circuit 153 to output the right channel audio signal buffered in the memory 152 to the second speaker 132 and the fourth speaker 134 currently located on the opposite right side. It is thereby achieved that the sound played has a stereo effect when the display device 100 is in the horizontal presentation state.
In this embodiment, the first frame is the upper frame 121 in the initial state of the display device 100 in the horizontal display state, in other examples, the first frame may also be any other frame, for example, the first frame may also be the left frame 123, when the vertical display state in the above embodiments is the horizontal display state, the display device 100 may rotate 90 ° counterclockwise, and in other examples, the display device 100 may also rotate 180 ° or 270 ° or the like, as long as it is ensured that the control unit 151 outputs the left channel audio signal to the speaker located in the left frame of the display screen or the speaker located on the relatively left side, and outputs the right channel audio signal to the speaker located in the right frame of the display screen or the speaker located on the relatively right side.
