Kind Code:
A1
Abstract:
Provided by the present application is a sound-generating component, the sound-generating component comprising a lower housing provided with a first accommodating space and an upper housing that has a second accommodating space and that is disposed opposite to the lower housing at a interval. The sound-generating component comprises: a first magnet housed in the first accommodating space and a second magnet and coil housed in the second accommodating space. The lower housing has a first open end facing the upper housing, the upper housing having a second open end disposed opposite the first open end, and the upper housing comprising a bottom wall disposed opposite the second opening end. The sound-generating component further comprises a magnetic guide column fixed on the bottom wall, the coil being coupled onto the magnetic guide column, and the second magnet being disposed at an interval on a peripheral side of the coil. The sound-generating component comprises a third magnet which is housed in the first accommodating space and is arranged on a peripheral side of the first magnet. The described magnetic circuit system is designed to counteract internal suction and effectively reduce the requirements for screen assembly.
