Display devices and electronic equipment

Abstract

This application provides a display device and an electronic device. The display device includes a display screen, a sound-emitting assembly, and a bass reflex device. A first sound outlet is provided on the display side; the display screen includes a housing and a display panel, forming a receiving cavity between them, and the first sound outlet communicates with the receiving cavity. The sound-emitting assembly includes a first sound-emitting module disposed within the receiving cavity, and its rear cavity communicates with the receiving cavity. The bass reflex device is disposed between the first sound outlet and the first sound-emitting module, and cooperates with the housing and the display panel to form a bass reflex tube; the end of the bass reflex device is spaced apart from the housing to form a bass reflex inlet, which communicates with the receiving cavity, and the bass reflex outlet communicates with the first sound outlet. The display device and electronic device of this application can improve low-frequency performance.

Claims

1. A display device, comprising: A display screen having a display side and a non-display side, the display side of the display screen having a first sound outlet; the display screen includes a housing and a display panel mounted on the housing, the display panel being located on the display side, a receiving cavity being formed between the housing and the display panel, the first sound outlet communicating with the receiving cavity; a sound-emitting assembly including a first sound-emitting module, the first sound-emitting module being disposed within the receiving cavity, and the rear cavity of the first sound-emitting module communicating with the receiving cavity; a phase-reversing component, the phase-reversing component being disposed within the receiving cavity and located between the first sound outlet and the first sound-emitting module, the phase-reversing component, the housing, and the display panel cooperating to form a phase-reversing sound tube, the end of the phase-reversing component being spaced apart from the housing and cooperating with the housing and the display panel to form a phase-reversing sound inlet of the phase-reversing sound tube, the phase-reversing sound inlet communicating with the receiving cavity, and a phase-reversing sound outlet of the phase-reversing sound tube communicating with the first sound outlet.

2. The display device as claimed in claim 1, wherein, The phase inversion tube includes two interconnected phase inversion tube sections, and the two phase inversion tube sections are respectively provided with phase inversion inlets at both ends of the phase inversion component.

3. The display device as claimed in claim 1, wherein, The phase inverter includes a first support portion and two second support portions connected to both ends of the first support portion. The second support portions are arc-shaped and bend toward the first sound-emitting module.

4. The display device as claimed in claim 1, wherein, The first sound outlet and the first sound-emitting module are arranged at intervals. In the arrangement direction of the first sound outlet and the first sound-emitting module, the distance between the phase inverter and the first sound outlet is less than the distance between the phase inverter and the first sound-emitting module.

5. The display device as claimed in claim 1, wherein, The housing has a first protrusion, which has a sound cavity. The phase-reversing sound outlet is located on the first protrusion and communicates with the sound cavity. The first sound outlet is also communicated with the sound cavity.

6. The display device as claimed in any one of claims 1 to 5, wherein, The sound-emitting component further includes a second sound-emitting module. The sound emitted by the first sound-emitting module is located in a first frequency band, and the sound emitted by the second sound-emitting module is located in a second frequency band, which is greater than the first frequency band. The second sound-emitting module is disposed in the receiving cavity, and the rear cavity of the second sound-emitting module is connected to the receiving cavity. The display side of the display screen is provided with a second sound outlet, and the front cavity of the second sound-emitting module is connected to the second sound outlet.

7. The display device as claimed in claim 6, wherein, The second sound-emitting module is provided in a plurality of units, including a feature sound-emitting module disposed on the side of the phase inverter opposite to the first sound-emitting module, and the rear cavity of the feature sound-emitting module is connected to the interior of the phase inverter tube.

8. The display device as claimed in any one of claims 1 to 5, wherein, The first sound-generating module includes a voice coil and a magnetic circuit assembly. The voice coil is disposed in one of the housing and the display panel, and the magnetic circuit assembly is disposed in the other of the housing and the display panel. The voice coil is energized and cooperates with the magnetic circuit assembly to drive the display panel to vibrate and generate sound. The voice coil and the magnetic circuit assembly are spaced apart to form the rear cavity of the first sound-generating module.

9. The display device as claimed in any one of claims 1 to 5, wherein, The display device also includes a buffer assembly disposed at the edge of the display panel and connected between the display panel and the housing.

10. An electronic device comprising a display device as described in any one of claims 1 to 9.
