Concentricity for solving to bring because of U ferrum and the gluing connection of frame is poor, cost high, efficiency is low and scattered
The problem of hot difference, this utility model provides a kind of loudspeaker monomer, as shown in Figure 1 to Figure 3,
Including U ferrum 1, frame 2 and back cover 3, the shape of the shape of described back cover 3 and described U ferrum 1 is mutually
Joining, described U ferrum 1 is positioned in described back cover 3, and the outer surface of the sidewall of described back cover 3 is provided with card
Conjunction portion, the inner surface of described frame 2 is provided with holding division, and described holding section matches with described holding division
Closing, to be fixed in described frame 2 by described back cover 3, the outer surface of the sidewall of above-mentioned back cover 3 is
Referring to the sidewall surface away from U ferrum 1 of back cover 3, the inner surface of frame 2 refers to that frame 2 is adjacent to U ferrum
Surface；The sidewall of above-mentioned U ferrum 1 can be with the inner surface interference fit of frame 2 more securely to fix
In frame 2, or the sidewall of U ferrum 1 can be with the inner surface interference fit of the sidewall of back cover 3 with more
It is firmly secured in back cover 3, or the free end of the sidewall of U ferrum 1 can offset with frame 2, the end
The diapire of wall and back cover 3 offsets more securely to be fixed between frame 2 and back cover 3, this area skill
Art personnel can select the suitable fixed form of U ferrum 1 according to the actual requirements；After above-mentioned holding section can be oneself
Projection on the wall outer surface of shell 3, holding division are to match with projection on the inner surface of frame 2
Groove, or holding section be fixedly connected on back cover 3 upper clipping claw, holding division is the inner surface of frame 2
The upper cavernous structure matched with claw, as long as can realize being fixed together frame 2 and back cover 3
Structure；Above-mentioned back cover 3 can be plastic material or metal material, it is therefore preferable to metal material,
Preferably to dispel the heat.Magnet 4 of the present utility model, washer 5 and voice coil loudspeaker voice coil 6 are by order from the bottom to top
Being sequentially stacked in U ferrum 1, the fixed part of vibrating diaphragm 7 is fixed together with frame 2.
This utility model passes through to be fixed in frame 2 by back cover 3 coordinating between holding section with holding division,
Thus the position that will be located in the U ferrum 1 in back cover 3 is fixed, the fixed form of this U ferrum 1
Need not gluing between U ferrum 1 and frame 2 again, thus between U ferrum and frame, need not reserved one
Requirement fixed by the glue of depositing that fixed gap meets in coating technique, is conducive to avoiding between U ferrum and frame
The poor problem of concentricity；And the assembling between frame 2 and back cover 3 is simply, be conducive to simplifying
Produce Wiring technology, reduce and produce line human input, thus reduce cost, improve efficiency；Additionally, U ferrum 1
