[0030] Figures 1-7 This is a schematic diagram of an electronic device according to several embodiments of the present invention. (Refer to...) Figures 1-7 This utility model provides an electronic device, which includes a support column 10, a first speaker array 20 disposed on the support column 10, and a display screen 30. The support column 10 has a display screen mounting structure 11, and the display screen 30 is connected to the display screen mounting structure 11 to be connected to the support column 10. (See reference...) Figure 2 and Figure 5 The electronic device also includes a control circuit 40, which is electrically connected to the first speaker array 20 and the display screen 30, and controls the display screen 30 to play images and controls the speakers in the first speaker array 20 to play audio.

[0031] The control circuit 40 may include a communication interface that receives one or more image and audio data that the electronic device needs to output from an external source via wired or wireless means. The image data received by the communication interface can be output through the display screen 30, and the audio data received through the communication interface can be output through a speaker.

[0032] The communication interface can receive image data via wired connections, such as through HDMI (High-Definition Multimedia Interface), SDI (Serial Digital Interface), DisplayPort (DP), Ethernet, or other methods. The communication interface can receive audio data via wired connections, such as through TRS (Tip-Ring-Sleeve), optical audio, XLR, RCA, Ethernet, or other methods. The communication interface can receive image or audio data wirelessly, such as through Wi-Fi, Bluetooth, cellular networks, millimeter wave, or other methods.

[0033] The control circuit 40 may include a memory for storing image data, audio data, or other data. The display screen 30 may be controlled by the control circuit 40 to display image data pre-stored in the memory, and the speaker may be controlled by the control circuit 40 to play audio data pre-stored in the memory. Additionally, the memory may also temporarily store image data, audio data, or other data received from the communication interface.

[0034] The electronic device may also include a human-machine interface (HMI) to receive control commands sent by the user. The control circuit 40 can then control various components within the electronic device according to these commands. For example, the user can input a volume adjustment command through the HMI to cause the control circuit 5 to adjust the speaker's output level. As another example, the control circuit 5 can output an image through the display screen 3 and audio through the speaker based on a video playback command input through the HMI.

[0035] In this embodiment of the utility model, reference is made to Figure 3 , Figure 4 and Figure 6 A reference plane P1 is defined, which passes through the central axis CX of the support column. Optionally, the center of the display screen 30 can be located at the reference plane P1, that is, the reference plane P1 is the middle position of the electronic device. When the user is directly in front of the electronic device, the user is also located on the reference plane P1.

[0036] The first speaker array 20 includes multiple speakers, for example, Figures 1-3 The first speaker array 20 of the electronic device shown includes two speakers: a first speaker 21 and a second speaker 22. Figures 4-7The illustrated electronic device's first speaker array 20 includes four speakers: a first speaker 21, a second speaker 22, a third speaker 23, and a fourth speaker 24. Optionally, the axis of at least one speaker in the first speaker array 20 may be substantially parallel to the horizontal plane. Alternatively, depending on the application scenario of the electronic device, the axis of the speakers in the first speaker array 20 may be slightly tilted upwards or downwards to match the user's usage needs. In this embodiment, the control circuit 40 is configured to control the speakers in the first speaker array 20 to output high-frequency sound waves. Each speaker in the first speaker array 20 may be a high-frequency speaker or a full-range speaker. The projections of the axes of at least two speakers in the first speaker array 20 onto the horizontal plane form a predetermined first angle α and are mirror-symmetric about a reference plane P1. For example, the projections of the axis AX1 of the first speaker 21 onto the horizontal plane and the projections of the axis AX2 of the second speaker 22 onto the horizontal plane are mirror-symmetric about the reference plane P1, and the angle between the projections of the axis AX1 of the first speaker 21 onto the horizontal plane and the projections of the axis AX2 of the second speaker 22 onto the horizontal plane is the first angle α. Furthermore, the sound-emitting surfaces of the first speaker 21 and the second speaker 22 are arranged opposite to each other and located on opposite sides of the reference plane P1. Thus, the first speaker array 20 includes at least two speakers oriented in different directions, allowing the sound waves emitted by the first speaker array 20 to cover a wider range. Even if the user deviates from the reference plane P1, the high-frequency sound waves emitted by the first speaker array 20 experience less attenuation upon reaching the user's location, ensuring the high-frequency sound quality of the electronic device.

[0037] The specific size of the first included angle α can be determined through acoustic simulation or experimentation based on the application scenario and other configurations of the electronic device, to ensure that users can obtain a good acoustic experience in different positions. In this embodiment, the first included angle α is 60°, that is, the angle between the projection of the axis AX1 of the first speaker 21 on the horizontal plane and the reference plane P1 is approximately 30°, and the angle between the projection of the axis AX2 of the second speaker 22 on the horizontal plane and the reference plane P1 is approximately 30°. Figure 8 This is a comparison diagram of the frequency response curves of the electronic device in this embodiment and the electronic device in the comparative example at a 45° angle to the reference plane P1. Curve S1 represents the frequency response curve of the comparative example, and curve S2 represents the frequency response curve of the electronic device in this embodiment. The speakers of the electronic devices in the comparative example are all mounted on the reference plane P1, and their axes are parallel to the reference plane P1. (Refer to...) Figure 8 The electronic device in this embodiment has an extended high-frequency range after 15kHz, and the amplitude at the 20kHz frequency point is increased by more than 10dB compared to the comparative example.

[0038] Each speaker in the first speaker array 20 can be mounted at the same height on the support column 10, or at least two speakers can be arranged sequentially along the extension direction of the support column 10, that is, at least two speakers in the first speaker array 20 can be arranged at different heights on the support column 10. For example, refer to Figure 3 The first speaker 21 and the second speaker 22 can be mounted at the same height on the support column 10. For example, refer to... Figure 4 The first speaker 21, the second speaker 22, the third speaker 23 and the fourth speaker 24 are set at different heights on the support column 10. This arrangement can be applied to support columns 10 with smaller diameters, making full use of the height space of the support column 10 to set multiple speakers.

[0039] In some embodiments, the first speaker array 20 has at least three speakers, and the multiple speakers in the first speaker array 20 are arranged circumferentially around the support column 10, facing different positions outside the support column 10, and the angle between the projection of the axis of each speaker in the first speaker array 20 onto the horizontal plane and the projection of the axis of at least one adjacent speaker onto the horizontal plane is equal to the first angle α.

[0040] In some embodiments, the plurality of speakers in the first speaker array 20 further include at least one third speaker 23 and / or at least one fourth speaker 24. (See also...) Figure 8 The angle formed between the axis AX3 of the third speaker 23 and the axis AX1 of the first speaker 21 is equal to the first angle α, and the sound-emitting surface of the third speaker 23 faces a different direction than the sound-emitting surface of the second speaker 22. Similarly, the angle formed between the axis AX4 of the fourth speaker 24 and the axis AX2 of the second speaker 22 is equal to the first angle α, and the sound-emitting surface of the fourth speaker 24 faces a different direction than the sound-emitting surface of the first speaker 21. This arrangement allows for better high-frequency sound effects from both the front and sides of the electronic device.

[0041] In one embodiment, refer to Figure 1 and Figure 7 The display mounting structure 11 is positioned above the first speaker array 20 to avoid obstructing its sound output. Optionally, after the display screen 30 is mounted on the display mounting structure 11, the lower edge of the display screen 30 is higher than the first speaker array 20 to reduce obstruction of the first speaker array 20's sound output, thereby ensuring the user's auditory experience. The display mounting structure 11 can be any structure capable of supporting the display screen 30 on the support column 10, allowing the display screen 30 to be fixed relative to the support column 10 or movable within a certain range. For example, the display mounting structure 11 may include a connecting rod, a hinge structure, or other structures.

[0042] Optionally, refer to Figure 4 and Figure 5 In some embodiments, the electronic device further includes a second speaker array 50, which is electrically connected to the control circuit 40 and spaced apart from the first speaker array 20. For example, the electronic device also includes a base 60 disposed at the bottom of the support column 10, and the second speaker array 50 may be partially or entirely disposed on the base 60. The control circuit 40 also controls the second speaker array 50 to play audio. The second speaker array 50 may include one or more speakers, and the audio frequency bands played by the speakers in the second speaker array 50 may overlap or offset from the audio frequency bands played by the speakers in the first speaker array 20. For example, when the second speaker array 50 is disposed on the base 60, the second speaker array 50 may include one or more low-frequency speakers.

[0043] This invention provides an electronic device that, by mirroring the projections of the axes of at least two speakers of a first speaker array 20 mounted on a support column 10 onto a horizontal plane about a reference plane P1 and forming a predetermined first included angle α, wherein the reference plane P1 passes through the central axis CX of the support column, allows the sound waves of the first speaker array 20 to cover a large area. Even if the user is not directly in front of the display screen 30, the high-frequency sound waves emitted by the first speaker array 20 will have less attenuation when reaching the user's location, thereby ensuring the high-frequency sound quality of the electronic device.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
