Abstract
The present disclosure discloses a sound device comprising: a metal frame; a vibration system fixed to metal frame; a magnetic system fixed to metal frame driving the vibration system to vibrate; the magnetic system includes a lower clamp plate, a main magnet fixed to the side of the lower clamp plate near the vibration system, and a sub-magnet set around the main magnet and spaced apart from the main magnet to form a magnetic gap; the sound device also includes a location pin fixed to the lower clamp plate, the location pin is formed on the circumference of the lower clamp plate by injection molding, and the end of the location pin away from the lower clamp plate is attached to the metal frame to form a positioning of the metal frame. The present disclosure can make the lower clamp plate positioned with the metal frame through the location pin, thus avoiding the problem that the lower clamp plate cannot be positioned with the metal frame.
