Abstract:
Provided is a loudspeaker cabinet. The loudspeaker cabinet comprises a shell with an accommodating space, a sound production unit accommodated in the shell and dividing the accommodating space into a front cavity and a rear cavity, and a soldering lug. The sound production unit comprises a diaphragm, a voice coil for driving the diaphragm to vibrate and produce sound, and a flexible circuit board electrically connected to the voice coil; the shell is further provided with a bottom wall which is opposite to the diaphragm and forms the front cavity with the diaphragm in an enclosing manner; a boss is formed by extending from the bottom wall to the interior of the rear cavity; the soldering lug is provided with an electrical connection portion fixed on the boss; the flexible circuit board extends to form a solder pad parallel to the bottom wall; the solder pad is arranged on the electrical connection portion; a through hole is formed in the solder pad in a penetrating manner; a protrusion penetrating through the through hole is arranged on the electrical connection portion; and the protrusion is tin-soldered to the solder pad. According to the loudspeaker cabinet provided in the present invention, it is ensured that the soldering lug and the flexible circuit board bear a certain pulling force in the horizontal direction, and furthermore, by means of the structure of the protrusion, a superficial area in contact with a tin layer is increased, thereby ensuring that the soldering lug and the flexible circuit board have good soldering and conduction effects.
