Abstract:
The present disclosure provides speaker device. The speaker device includes frame, vibration unit fixed to frame and magnetic circuit unit driving vibration unit to vibrate and produce sound, where magnetic circuit unit is provided with magnetic gap; vibration unit includes diaphragm, voice coil inserted in magnetic gap to drive diaphragm to vibrate and holder connected to diaphragm; side of frame close to diaphragm is at least partially embedded into diaphragm; first surface is formed on side of frame away from diaphragm; second surface is formed on side of diaphragm close to magnetic circuit unit. The present disclosure solves problem of glue overflow of holder by means of reserved space between frame and diaphragm. In addition, by using first surface of holder as supporting surface, present disclosure improves dimensional consistency of gluing with flexible printed circuit (FPC), etc., thereby improving product yield.
