Description

Technical Field

[0001] The utility model relates to the technical field of sound boxes, and in particular to a mounting structure of an input and output PCBA board of a sound box. Background Art

[0002] A speaker is a device that can convert audio signals into sound. The speakers currently on the market usually include a speaker box and a main control PCBA board installed inside the speaker box. The main control PCBA board is usually equipped with a USB TYPE-C connector and an audio input connector. The speaker box is equipped with an opening, and the USB TYPE-C connector and the audio input connector extend out of the opening of the speaker box. In addition, there is a type of speaker that has a separate input and output PCBA board. The input and output PCBA board is connected to the main control PCBA board through an FPC cable. The USB TYPE-C connector and the audio input connector are arranged on the input and output PCBA board, and the USB TYPE-C connector and the audio input connector also extend out of the opening of the speaker box.

[0003] As people's requirements for speakers are getting higher and higher, the speaker cabinets of some speakers are made of wood. The input and output PCBA board installation structure of such wooden speakers mainly has the following technical problems: on the one hand, it is difficult for wooden speakers to provide a fixing part for the input and output PCBA board, which makes it difficult to assemble and fix the input and output PCBA board; on the other hand, the wall thickness of the wooden speaker is relatively thick, and the length of the USB TYPE-C connector and the audio input connector is often shorter than the wall thickness of the wooden speaker, which makes it difficult to plug in. The solution of technical personnel in this field is often to design the opening size of the speaker cabinet to be relatively large, so that when the USB TYPE-C connector or the audio input connector is plugged in, it will not be affected by the speaker cabinet; but the speaker cabinet with an enlarged opening will cause new problems, mainly causing sound leakage at the opening, reducing the overall sound effect of the speaker, and at the same time, it is easy to see the internal components of the speaker from the opening, affecting the overall visual effect. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a mounting structure for an input and output PCBA board of a speaker in view of the deficiencies of the above-mentioned prior art. The mounting structure can use the PCBA board fixing seat of the PCBA board mounting cavity to simultaneously fix the input and output PCBA board and the sealing plastic cover, and the assembly is simple and the fixing is stable. The mounting structure can use the sealing plastic cover to plug into the second opening of the outer box body of the speaker to avoid sound leakage from the side of the speaker and to avoid seeing the internal components of the speaker from the second opening. The mounting structure can enable the USB TYPE-C connector of the input and output PCBA board to be inserted into the first through hole of the sealing plastic cover, so that the USB TYPE-C connector is easy to plug in.
