Description

Technical Field

[0001] The invention relates to the technical field of mobile phone components, and in particular to a smart phone speaker fixing bracket. Background Art

[0002] Each component inside a smartphone requires a different phone holder to fix it. Today's phones pursue thinness and lightness. In order to maximize the use of the internal space of the phone, the phone holder, especially the speaker holder, requires a certain space as a sound cavity, and the speaker holder needs a more compact and reasonable layout.

[0003] According to Chinese patent CN208691300U, a mobile phone speaker bracket is disclosed. The speaker bracket is arranged on the mobile phone housing for arranging a speaker assembly. The speaker assembly includes a speaker and a wire arranged at one end of the speaker. The speaker is a square structure with rounded corners. The speaker bracket is provided with a first groove that is adapted to the shape of the speaker and a second groove that is arranged opposite to the speaker wire interface. The speaker is accommodated by the first groove and the second groove. However, the speaker bracket has a relatively single function and a large volume. It only has a single function of fixing the speaker. Its structure is relatively loose. In the face of increasingly thin and light mobile phones, it cannot meet the relatively narrow space inside the mobile phone.

[0004] Therefore, it is necessary to develop a smart phone speaker fixing bracket to solve the above problems. Utility Model Content
