Patent attributes
The invention provides a sound generator having a frame, a vibration system and a magnetic circuit system carried by the frame. The vibration system includes a diaphragm, a coil and an elastic support assembly. The diaphragm includes a first suspension ring fixed with the frame, a first dome at a center of the first suspension ring, and a second dome stacked on the first dome. The first dome includes a main body, a first wall, and a second wall extending perpendicularly from the first wall for connecting to the coil via the first wall. The first wall is connected to a side surface of the coil. The first wall and the second wall are used for elastically suspending the coil below the diaphragm. Thus, the sound generator has improved high frequency performance.
