The second portion 22 may be bonded to the reinforcement portion, and the reinforcement portion is bonded to the bearing surface 321 through an adhesive.
Preferably, as shown in fig. 2, a limit table 3211 may be further formed at an edge of the bearing surface 321, the limit table 3211 is used to position the connection portion 23, and the connection portion 23 of the flexible circuit board may be embedded in the limit table 3211. Under the restriction of the limit table 3211, the connecting portion 23 does not shift.
After the upper case 31 and the lower case 32 are fastened, a gap inevitably exists between the notch and the connection portion 23 of the flexible circuit board. In the embodiment of the invention, the connection part 23 and the notch can be sealed by gluing, so that the sealing performance of the sound generating device module is improved. Preferably, a first notch may be formed on the upper case at a position corresponding to the notch; and/or, a second notch may be formed on the lower case at a position corresponding to the notch. After the upper shell, the lower shell and the flexible circuit board are assembled, glue is injected to the surface of one side of the flexible circuit board through the first notch for sealing; the glue injection sealing can be carried out on the other side surface of the flexible circuit board through the second notch. Through this kind of structural design, can be sealed totally with the gap between notch and the flexible circuit board, more convenient, effectual realization module casing is sealed.
