Screen-based sound devices and electronic devices

Abstract

This application belongs to the field of loudspeaker technology, providing a screen-based sound-emitting device and electronic device. The device includes a screen and a sound-emitting component. The screen has a display side and a non-display side, with a first and a second sound outlet on the display side. The screen includes a housing and a display panel disposed on the housing, forming a receiving cavity between them, with the first sound outlet communicating with the receiving cavity. The sound-emitting component is disposed within the receiving cavity and includes a first and a second sound-emitting module, with the second sound-emitting module having a higher frequency band than the first sound-emitting module. The rear cavity of the first sound-emitting module communicates with the receiving cavity; the second sound-emitting module is disposed at the edge of the screen, with its rear cavity communicating with the receiving cavity and its front cavity communicating with the second sound outlet. The device and electronic device of this application can improve auditory performance.

Claims

1. A screen sound-emitting device, comprising: A screen having a display side and a non-display side, the display side having a first sound outlet and a second sound outlet; the screen including 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 plurality of sound-emitting modules all disposed within the receiving cavity, the sound-emitting modules including a first sound-emitting module and a second sound-emitting module, the sound-emitting frequency band of the second sound-emitting module being greater than that of the first sound-emitting module; the rear cavity of the first sound-emitting module communicating with the receiving cavity, the second sound-emitting module being disposed near the edge of the screen, and the rear cavity of the second sound-emitting module communicating with the receiving cavity, the front cavity of the second sound-emitting module communicating with the second sound outlet.

2. The screen sound-emitting device as claimed in claim 1, wherein, The second sound-emitting module is provided in one manner; or, the second sound-emitting module and the second sound outlet are provided in a plurality of ways, with the front cavity of the second sound-emitting module communicating with the corresponding second sound outlet.

3. The screen sound-emitting device as described in claim 2, wherein, The second sound holes are spaced apart along the circumference of the screen; or, the screen has a plurality of corners, and the second sound holes correspond one-to-one with the corners, with the second sound holes positioned close to the corresponding corner.

4. The screen sound-emitting device as claimed in claim 1, wherein, The first sound-emitting module is provided and is located near the geometric center of the screen; or, the first sound-emitting module is provided in multiples and is symmetrically arranged along a first axis of symmetry, which extends along the length or width direction of the screen.

5. The screen sound-emitting device as described in any one of claims 1 to 4, 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.

6. The screen sound-emitting device as described in any one of claims 1 to 4, wherein, The screen sound-emitting device also includes a support member disposed in the receiving cavity and located between the first sound outlet and the first sound-emitting module. The support member, the housing, and the display panel cooperate to form a bass reflex tube, and the bass reflex tube's bass reflex outlet is connected to the first sound outlet.

7. The screen sound-emitting device as described in any one of claims 1 to 4, wherein, The screen sound device also includes a buffer component located at the edge of the display panel and connected between the display panel and the housing.

8. The screen sound device as claimed in claim 7, wherein, The buffer assembly includes a first buffer portion extending along a first direction and a second buffer portion extending along a second direction. The first buffer portion is connected between the side of the display panel and the housing. The display panel has a display surface and a non-display surface facing the receiving cavity. The second buffer portion is connected between the non-display surface and the housing. Alternatively, the buffer assembly includes a buffer connector and a buffer member. The buffer connector is connected to the housing. The buffer member is located between the buffer connector and the display panel in the second direction and is connected to the buffer connector and the display panel. Wherein, the first direction is the thickness direction of the screen, and the second direction is perpendicular to the first direction.

9. The screen sound-emitting device as described in any one of claims 1 to 4, wherein, The first sound-emitting module is circular, elliptical, polygonal, or fan-shaped.

10. An electronic device comprising a screen sound-emitting device as described in any one of claims 1 to 9.
