Abstract

The invention discloses a miniature loudspeaker box. The miniature loudspeaker box comprises a case, a sound-making magnet fixed inside the case and a conductive coil surrounding the sound-making magnet. A first screw hole column used for fixing the sound-making magnet is arranged at one end of the sound-making magnet, and a first screw hole matched with the first screw hole column is formed in the corresponding portion of the case. The sound-making magnet is fixed in the case through a screw. According to the miniature loudspeaker box, due to the fact that the sound-making magnet is fixed in the case through the screw, screw fixation is firm, operation is simple, and the sound-making magnet is fixed in the case firmly.

Description

technical field [0001] The invention relates to the field of audio, more specifically, to a miniature audio. Background technique [0002] The USB data cable of the three-wire connector includes a USB plug matched with the USB interface, an earphone jack arranged side by side, and a charging plug matched with the USB jack on the computer or the charging adapter. [0003] I have designed a miniature audio system, which includes a housing, a sounding magnet fixed in the housing, a conductive coil arranged around the sounding magnet, a circuit board connected with the conductive coil with a wire and equipped with a USB interface, and a device A hollow sound cavity post communicated with the interior of the housing above the housing. The conductive coil on the outside of the sounding magnet will generate a magnetic field when it is energized, which will cause vibration between the sounding magnet and the winding part; in this way, the micro-audio will be connected to the sound ...
