Abstract

The present disclosure provides speaker device. speaker device includes frame, vibration unit fixed to frame and magnetic circuit unit fixed to the frame and driving vibration unit to vibrate and produce sound, where magnetic circuit unit is provided with magnetic gap; vibration unit includes diaphragm fixed to frame, holder fixed to diaphragm; holder includes bottom wall that is fixed to diaphragm and provided with pair of long edges and pair of short edges, and pair of side walls bending and extending from outer peripheries of pair of short edges of bottom wall to magnetic circuit unit; The disclosure effectively solves problem of material underflow during molding of diaphragm of speaker device. In this way, connection parts between side walls and elastic conductive assembly are prevented from being contaminated, thereby reducing risk of unstable gluing between side walls and elastic conductive assembly.
