The four locating holes 182 can be defined at two ends of the cover plate 121 adjacent to the third sidewall 114 and the fourth sidewall 115. The locating bulges 181 can be received in the corresponding locating holes 182 when the cover plate 11 covers the opening 110 (shown in FIG. 2).
FIG. 5 illustrates that the separator plate 131 can be positioned between the resonant sheets 20 and the biasing magnetic sheet 30, and the two resonant sheets 20 can be positioned between the pressing members 122 and the supporting members 133.
In operation, the biasing magnetic sheet 30 can be positioned on the bottom plate 111, and the separator plate 131 can rotate relative to the main body 11 and cover the biasing magnetic sheet 30. The latching blocks 171 can be latched with the corresponding protrusions 172 to fix the separator plate 131 in the main body 11. Then, the two resonant sheets 20 can be stacked on the three supporting members 133. The cover plate 121 can rotate to cover the opening 110, and the locating bulges 181 can be inserted into the corresponding locating holes 182 to align the cover plate 121 to the opening 110. At the same time, the two latch hooks 161 can be coupled to the corresponding latch grooves 162 to fix the cover 12 to the main body 11.
The housing 10 of the acoustic magnetic tag 100 can be molded in one body, so the housing 10 has convenience in use and simplified manufacture process. The cover 12 and the partition 13 can be rotatably connected to the housing 10, the cover 12 can be fixed to the main body 11 by the lock assembly 16, and the partition 13 can be fixed to the housing by the latch assembly 17. Therefore, the acoustic magnetic tag 100 has a simplified assembly process.
FIG. 6 illustrates an acoustic magnetic tag 200 of a second embodiment of this disclosure. The acoustic magnetic tag 200 can include a housing 210. The housing 210 can include a main body 211, a cover 212, and a partition 213.

One end of the main body 211 can define an opening 2110, the first connecting portion 214 can connect the partition 213 and the main body 211, and the second connecting portion 215 can connect the cover 212 and the main body 211. The first connecting portion 214 and the second connecting portion 215 can be bent, thereby the partition 13 can be received in the main body 211, and the cover 212 can cover the opening 2110. The main body 211 can include a bottom plate 2111, a first sidewall 2112, a second sidewall 2113, a third sidewall 2114, and a fourth sidewall 2115. The acoustic magnetic tag 200 can be similar to the acoustic magnetic tag 100, except that, the lock assembly 216 includes a lock catch 2161 and a lock groove 2162. The lock catch 2161 can be positioned at one side of the cover 212 away from the second connecting portion 215, and the lock groove 2162 can be defined on a surface of the first sidewall 2112 toward the second sidewall 2113. The lock catch 2161 can be snapped into the corresponding latch groove 2162 to fix the cover 212 to the main body 211.
The lock catch 2161 of the acoustic magnetic tag 200 can replace the latch hook 161. It is simpler to form the lock catch 2161 in a mold than the latch hook 161. Thereby, the complexity of manufacturing can be decreased and the manufacturing cost can be reduced.
