For example, in fig. 1, the notebook computer 200 may include two speaker assemblies 100, the two speaker assemblies 100 may have the same structure, and the two speaker assemblies 100 may be symmetrically disposed in the housing 203.
It should be noted that the location of the speaker assembly 100 in the housing 203 may be flexibly set, and fig. 1 only shows one example of the location of the speaker assembly 100 in the housing 203, which is not to be considered as a specific limitation of the present application.

The specific structure of the speaker assembly will be described in detail with reference to the accompanying drawings.
Referring to fig. 3 or 4, the embodiment of the present application provides a speaker assembly 100, where the speaker assembly 100 may convert an audio electrical signal into a sound signal, and an electronic device (e.g., a notebook computer 200) may play music through the speaker assembly 100, or implement a hands-free call. Specifically, the speaker assembly 100 may include at least: a bracket 11 and at least two speaker modules 10, wherein each speaker module 10 of the at least two speaker modules 10 has a first surface 101 and a second surface 102 opposite to each other.

In this way, the two adjacent speaker modules 10 can be guaranteed to be oppositely arranged, the direction of the reverse force generated by one speaker module 10 of the two adjacent speaker modules 10 relative to the middle frame 201 of the notebook computer 200 is opposite to the direction of the reverse force generated by the other speaker module 10 of the two adjacent speaker modules 10 relative to the middle frame 201 of the notebook computer 200, so that the reverse force generated by the speaker assembly 100 relative to the middle frame 201 can be greatly counteracted, the output force of the speaker assembly 100 to the notebook computer 200 in the working process can be effectively reduced, the problem of noise occurrence of the notebook computer 200 can be further reduced or avoided, the conversation effect and the external sound quality of the notebook computer 200 can be improved, and the experience of a user can be improved to a certain extent.
With continued reference to fig. 4, in an embodiment of the present application, at least two speaker modules 10 may include: the first speaker module 20 and the second speaker module 30 are connected through the bracket 11, and the first surface 101 of the first speaker module 20 and the second surface 102 of the second speaker module 30 are located on the first side of the bracket 11, and the second surface 102 of the first speaker module 20 and the first surface 101 of the second speaker module 30 are located on the second side of the bracket 11.
It will be appreciated that in the embodiment of the present application, the physical structures and acoustic parameters of the first speaker module 20 and the second speaker module 30 are consistent, so that the first speaker module 20 and the second speaker module 30 are oppositely disposed, and the direction of the reverse force generated by the first speaker module 20 relative to the middle frame of the notebook computer 200 is opposite to the direction of the reverse force generated by the second speaker module 30 relative to the middle frame of the notebook computer 200, so that the reverse force generated by the speaker assembly 100 relative to the middle frame can be completely offset.
Alternatively, in other embodiments, the physical structures and acoustic parameters of the first speaker module 20 and the second speaker module 30 may be inconsistent, so that the directions of the reverse force generated by the first speaker module 20 and the second speaker module 30 relative to the middle frame of the notebook computer 200 are opposite to the directions of the reverse force generated by the second speaker module 30 relative to the middle frame of the notebook computer 200, and the reverse force generated by the speaker assembly 100 relative to the middle frame can still be offset, so that the output force of the speaker assembly 100 to the notebook computer 200 during the working process can be effectively reduced to a certain extent.
In one possible implementation, referring to fig. 5, the stand 11 may include: a first portion 111 and a second portion 112, wherein the first portion 111 is connected to one of the first speaker module 20 and the second speaker module 30, the second portion 112 is connected to the other of the first speaker module 20 and the second speaker module 30, and the first portion 111 is connected to the second portion 112. Illustratively, in fig. 3, the first portion 111 is connected to the first speaker module 20 and the second portion 112 is connected to the second speaker module 30.
The first portion 111 is connected to the second portion 112 to ensure that the first speaker module 20 and the second speaker module 30 are connected.
