Wherein, said many group connecting portions, this each group connecting portion is divided into two parts, and the first pontes two ends connect an end of a housing and an elastic part respectively, and two ends, second coupling part connect the other end and the inside casing of same elastic part respectively.
Wherein, flat elastic piece all adopted the wet etching process one-shot forming under the upper flat plate shell fragment reached, and wherein the upper flat plate shell fragment is an integral structure, and following flat elastic piece is a split-type structural.
Wherein, the described split-type structural of flat elastic piece is down cut apart along center line, is divided into symmetrical first flat elastic piece part and the second flat elastic piece part.
Wherein, a said wherein side of flat elastic piece down is provided with two splicing ears, and said splicing ear is one-body molded and symmetrical along center line with following flat elastic piece.
Wherein, the said part of flat elastic piece first flat elastic piece down partly is connected through contiguous block with second flat elastic piece.
Wherein, said contiguous block joins with said inside casing in the inside casing inboard of following flat elastic piece, and is provided with the precompressed trace in the junction.
Implement the flat elastic piece group of the utility model; Has following beneficial effect: because the following flat elastic piece of voice coil motor is an integral type; After accomplishing with the fixing assembling of loop; Peel off contiguous block with iron tweezers or other sharp objects at precompressed trace place along contiguous block is connected with the elastic part of two flat elastic pieces, does not have by other tools, has improved production efficiency.Simultaneously, make down two flat elastic piece part accurate positionings of flat elastic piece, not yielding, improved the quality of voice coil motor.
