Glue groove, the lower clamp plate are connect with the magnet steel by the glue groove gluing.
Preferably, the glue groove is set to the center of the lower clamp plate.
Preferably, the glue groove is rectangular or round.
Preferably, the glue groove is in a ring.
Preferably, the lower clamp plate includes main part and from the both ends of the main part to far from the main part side
To the extension of extension, the glue groove is set to the center of the main part.
Preferably, the area of the glue groove is less than the floor space of the magnet steel.
The utility model also provides a kind of loud speaker, and the loud speaker includes such as any of the above-described magnetic circuit system.
Compared with the relevant technologies, magnetic circuit system provided by the utility model is equipped with glue groove, the glue groove in lower clamp plate
It is connected by the glue groove gluing for accommodating glue, the lower clamp plate and the magnet steel, glue preferentially fills up institute when glued
Glue groove is stated, to ensure glued uniformity, magnet steel is avoided to fall.
【Description of the drawings】
