[embodiment]

The utility model is described in further detail below in conjunction with drawings and embodiments.

As shown in Figures 2 and 3, the multi-functional acoustical generator integrated system 10 of the utility model comprises the magnet frame 21, magnet steel 22, mass group and the latch plate 23 that constitute vibration unit, constitute voice coil loudspeaker voice coil 26, the vibrating diaphragm 27 of phonation unit, which is provided with the loam cake 28 of sound hole 280, base 30, back cover 31.

Base 30 comprises upper surface 301 and lower surface 302, which is provided with an accepting hole 303, and side is provided with the conducting terminal 29 that realization electrically conducts.

The mass group comprises the first quality loop piece 24 and is designed to the second bowl-shape quality loop piece 25.On the second quality loop piece 25, also be provided with perforate 250.

More than the assembly relation of each parts as follows: back cover 31 links to each other with the lower surface 302 of base 30 to form back cavity 300, latch plate 23 is fixed in the base accepting hole 303, magnet frame 21 be suspended on the latch plate 23 and be contained in accepting hole 303 and back cavity 300 in, magnet steel 22 is contained in magnet frame 21 and forms magnetic gap with magnet frame, voice coil loudspeaker voice coil 26 is positioned at magnetic gap and links to each other with vibrating diaphragm 27, loam cake 28 links to each other with vibrating diaphragm 27 and is fixedly arranged on the upper surface 301 of base 30, the first quality loop piece 24 and the second quality loop piece 25 all are socketed in the bottom of magnet frame 21, and the first quality loop piece 24 is contained in the second quality loop piece 25.
