Problems solved by technology
The glue may be degummed after a certain period of time, causing the main circuit board to have a certain displacement on the support column. Once the circuit board is displaced, the switch, USB interface, audio input hole, charging interface and switch hole, USB avoidance port, and headphone jack may be damaged. , The charging socket cannot be opposite, which will affect the use of the miniature audio

The invention discloses a miniature sound box. The miniature sound box comprises a body and a main circuit board, wherein one side of the main circuit board is provided with a switch, a charge interface, a USB interface and an audio output hole, a first baffle which extends inwards and is matched with the main circuit board in shape is arranged in the body and provided with first screw hole columns, the main circuit board is provided with first screw holes opposite to the first screw hole columns and is fixed into the body through screws, and a first voiding hole, a second voiding hole, a third voiding hole and a forth voiding hole are formed in corresponding positions of the body and are in one-to-one correspondence to the switch, the charge interface, the USB interface and the audio output hole. Because the main circuit board is fixed into the body through the screws and screw fixation is firm, the situation that main circuit board is not fixed firmly is avoided; by the adoption of screw fixation, operation is easy, and installation is facilitated.
Description
technical field [0001] The invention relates to the field of audio, more specifically, to a miniature audio. Background technique [0002] I have designed a miniature audio system, which includes a main body with a built-in speaker and a main circuit board and a base for supporting a battery built in the main body; Frame, the main body of the miniature audio system is provided with two speakers, which are fixed on the relative positions of the left shell and the right shell respectively with glue; The upper end is provided with a downward-sloping cutout, and the middle frame includes a first closed end closing the upper cutouts of the left and right shells, a second closed end closing the bottoms of the left and right shells, and a A supporting column between the first closed end and the second closed end. The left shell, the right shell and the middle frame are detachably fixed among the three. The base is in the shape of a round platform, and a button circuit board with...
