Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0020] The invention discloses a sound box. The sound box comprises an upper case, a lower case, a circuit board, a horn, a sound hole and a cover. The circuit board is arranged in the lower case, and a fixing device for fixing the circuit board is arranged in the lower case. Because the circuit board fixing device is provided in the present invention, the circuit board can be directly fixed on the circuit board fixing device, which saves screw installation, saves time and effort, and improves the assembly efficiency of the sound box.

[0021] Such as figure 1 , figure 2 As shown, the fixing device includes a clip 2, and the clip 2 is provided with a barb 3 for clamping the circuit board. The barbs are used to catch the board. The barb 3 is arranged on the top of the clip 2 . The barb is formed by extending outward along the clip, and the...

Abstract

The invention discloses a sound box, which comprises an upper shell, a lower shell, a circuit board, a loudspeaker, a sound output hole and a cover, wherein the circuit board is arranged in the lower shell, and a fixing device used for fixing the circuit board is arranged in the lower shell. Because the sound box is provided with the circuit board fixing device, the circuit board can be directly fixed on the circuit board fixing device, installation by screws is omitted, time and labor are saved, and the assembly efficiency of the sound box is improved.

Description

technical field [0001] The invention relates to the field of household appliances, and more specifically, to a sound box. Background technique [0002] I have designed a sound box, which includes an upper shell, a lower shell, a circuit board, a speaker, a sound hole, and a cover for closing the sound hole. The sound hole and the cover are arranged on the upper shell, and one end of the cover is There is a pin shaft, the cover is fixed on the upper shell through the pin shaft, the circuit board and the speaker are arranged in the lower shell, the cover can be rotated through the pin shaft, so that it is convenient to open the cover and close the sound hole, and then realize the speaker on the speaker Hidden setting, just open the cover when in use, and close the cover when not in use to close the speaker, the circuit board is fixed on the speaker shell with screws. This program is unpublished. Since the circuit board is fixed on the sound box shell by a plurality of screws...
