The method comprises the steps of: (a) preparing a chuck ring material plate and a vibrating diaphragm material plate, and stamping a number of chuck ring inner holes in the chuck ring material plate; (b) coating an adhesive on the upper surface of the chuck ring material plate stamped with the chuck ring inner holes; (c) bonding the vibrating diaphragm material plate to the upper surface of the chuck ring material plate coated with an adhesive; (d) downwards stamping the part of the vibrating diaphragm material plate corresponding to the chuck ring inner holes into the central part of a vibrating diaphragm; and (e) stamping to form the outer edge of the assembly around the chuck ring inner holes, and removing the assembly from the material plate. ## Claims ### Claim 1 An assembling method for micro-loudspeaker assemblies, the method comprising: (a) stamping out a plurality of inner holes of chuck rings in a chuck ring material plate, wherein shapes of the plurality of inner holes are the same as shapes of central parts of vibrating diaphragms; (b) coating an adhesive on an upper surface of the chuck ring material plate stamped with the inner holes of chuck rings; (c) bonding a vibrating diaphragm material plate to the upper surface of the chuck ring material plate coated with the adhesive; (d) downwardly stamping out a part of the vibrating diaphragm material plate aligning with the inner holes of chuck rings so as to form central parts of the vibrating diaphragms; and (e) stamping around the plurality of inner holes of chuck rings to form outer edges of the assemblies, and releasing the assemblies from the bonded material plates. ### Claim 2 (depends on 1) The assembling method for micro-loudspeaker assembly of claim 1, wherein in step (a), positioning holes are stamped out in the periphery of the chuck ring material plate. ### Claim 3 (depends on 1) The assembling method for micro-loudspeaker assembly of claim 1, wherein in step (a), a flexible printed circuit board (FPCB) integrated with several electric connecting parts is prepared, and inner holes of electric connecting part are stamped out in the FPCB; and between the steps (d) and (e), a second adhesive is coated on the surface of the FPCB stamped with the inner holes of electric connecting part, and then the FPCB is bonded to the upper surface of the vibrating diaphragm material plate, so that the inner holes of electric connecting part align with the inner holes of chuck rings in a one-to-one way. ### Claim 4 (depends on 3) The assembling method for micro-loudspeaker assembly of claim 3, wherein in step (a), positioning holes are stamped out in the periphery of the chuck ring material plate and the FPCB. ### Claim 5 (depends on 1) The assembling method for micro-loudspeaker assembly of claim 1, wherein in step (a), inner holes of electric connecting part are stamped out in a flexible printed circuit board (FPCB) integrated with several electric connecting parts; and between the steps (c) and (d), a second adhesive is coated on the surface of the FPCB stamped with the inner holes of electric connecting part, and then the FPCB is bonded to the upper surface of the vibrating diaphragm material plate, so that the inner holes of electric connecting part align with the inner holes of chuck rings in a one-to-one way. ### Claim 6 (depends on 5) The assembling method for micro-loudspeaker assembly of claim 5, wherein in step (a), positioning holes are stamped out in the periphery of the chuck ring material plate and the FPCB. ### Claim 7 (depends on 1) The assembling method for micro-loudspeaker assembly of claim 1, wherein in step (b), a third adhesive is printed on the periphery of the inner holes of chuck ring of the chuck ring material plate by screen-printing. ### Claim 8 (depends on 1) The assembling method for micro-loudspeaker assembly of claim 1, wherein the chuck ring material plate is made of metal material or plastic material.
