According to the electromagnetic exciter 300, the inner cavity of the end cover 240 is fully utilized to realize installation of the electromagnetic exciter 300, an installation space does not need to be reserved for the electromagnetic exciter 300 additionally, and installation convenience of the electromagnetic exciter 300 is improved.

During production, the electromagnetic actuator 300 may be installed from the end cap 240 after the door body 200 is formed by foaming, which is convenient for production and processing.

During maintenance, the cover plate 600 is directly detached, and the electromagnetic exciter 300 can be maintained, so that the maintenance convenience is improved.

The electromagnetic exciter 300 is hidden inside the end cover 240, and the appearance of the refrigerator product is not changed due to the addition of the electromagnetic exciter.

At least one electromagnetic exciter 300 is arranged in an inner cavity of the same end cover, and a plurality of sound sources can generate stereo effect, so that the experience is good.

In some embodiments of the present application, the electromagnetic exciter 300 is disposed in the internal cavity of the upper cover, and the electromagnetic exciter 300 is connected to the upper cover to drive the upper cover to vibrate and generate sound.

During sounding, the overhead electromagnetic exciter 300 is more convenient for sound to spread and propagate all around, and if the electromagnetic exciter 300 is arranged in the lower end cover, the scattered sound can be blocked by the bottom freezing chamber door body, so that the sound effect is influenced.

And the electromagnetic exciter is arranged on the door body in a sixth mounting mode: is arranged on the display panel cover plate.

Referring to fig. 18, the door body 200 is provided with a mounting box 400 for mounting the display panel 900, a transparent display panel cover plate 910 is disposed on the outer side of the display panel 900, and the display panel cover plate 910 is exposed from the front side opening of the mounting box 400, so that the contents displayed by the display panel 900 can be seen through the display panel cover plate 910; the display panel cover 900 and the door panel 210 at the front side of the door body 200 are positioned on the same vertical surface, and the appearance consistency is better.

An electromagnetic actuator 300 is provided in the mounting case 400, a sound substrate 500 is provided on the inner side of the display panel cover 900, and the vibration body of the electromagnetic actuator 300 is in contact with the sound substrate 500.

The mounting box 400 has a certain cavity structure, and the thickness of the display panel 900 attached to the display panel cover plate 910 is much larger than the thickness of the electromagnetic exciter 300 itself, so that when the electromagnetic exciter 300 is mounted on the back side of the display panel cover plate 910, a cavity is not required to be reserved for the mounting of the electromagnetic exciter 300 in the mounting box 400, and sufficient space is provided in the mounting box 400 for the electromagnetic exciter 300 to vibrate and sound.

The panel cover 910 may be extended to leave a position for mounting the electromagnetic actuator 300 except for a portion to be bonded to the panel 900.

The electromagnetic exciter 300 is hidden in the mounting box 400, and the appearance of the refrigerator product cannot be changed due to the addition of the electromagnetic exciter 300.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
