Technical Field

[0001] The present invention relates to the technical field of electronic products, and more specifically, to an electronic device. Background Art

[0002] With the rapid development of electronic devices, higher requirements are placed on the performance of speaker units of electronic devices. Large-sized speaker units are gradually used in products such as VR (virtual reality), AR (augmented reality) and tablet computers. However, the vibrations generated by large-sized speaker units during operation bring users a greater sense of vibration discomfort. The reason for this problem is that the current speaker units and the housing of the electronic device are usually fixed with UV glue and UV light hardening, which causes the vibration energy generated by the speaker units to be directly transmitted to the housing of the electronic device, and then to the user, thereby responding to the user experience. Summary of the invention

[0003] In view of the above problems, an object of the present invention is to provide an electronic device to solve the problem that the speaker unit vibrates and causes the entire device to vibrate due to the use of UV glue to fix the speaker unit and the device housing in the existing electronic device.

[0007] A structural component is arranged on the speaker unit, and the structural component extends into the liquid storage tank and is inserted into the elastic liquid in the liquid storage tank.

[0008] In addition, a preferred structure is that the vibration-damping spring sheet includes a housing fixing portion fixed to the housing, a shell fixing portion fixed to the speaker unit, and an elastic arm for connecting the housing fixing portion and the shell fixing portion, wherein:

[0015] In addition, a preferred structure is that the structural member includes a bottom wall and a side wall, wherein the bottom wall and the side wall are both annular structures, and the bottom wall and the side wall are arranged perpendicularly.

[0016] In addition, a preferred structure is that the bottom wall is injection-molded with the speaker unit, and the side walls extend into the liquid storage tank and merge into the elastic liquid in the liquid storage tank, thereby dividing the shell into a front sound cavity and a rear sound cavity.

[0017] In addition, a preferred structure is that the electronic device includes a head-mounted device and a tablet product.

[0038] The elastic arm is two bent parts connected in sequence. The two bent parts connected in sequence are connected to each other through a second connection part; the housing fixing part and the two bent parts connected in sequence are connected to each other through a first connection part, and the two bent parts connected in sequence are connected to the housing fixing part through a third connection part.
