At the same time, the first thick rod part 322 is adjacent to the thin rod part One end of 321 abuts against the inverted walls 22, so that the connecting rod 32 needs to further apply force to the inverted walls 22, thereby opening the limiting hole 215, so the inverted walls 22 The purpose of restricting the sounding device 3 from easily detaching from the buckle groove 212 can be achieved. In addition, the diameter D4 of the first thick rod and the diameter D5 of the second thick rod are both larger than the diameter D2 of the connecting hole of the support wall 21, so that the first thick rod 322 and the second thick rod 323 are exposed to The supporting wall 21 blocks and cannot extend through the engaging hole 216 along the axial direction of the engaging rod 32. As shown in FIG. 4, more specifically, the axial length L1 of the thin rod portion is the same as the thickness L2 of the support wall defining the engaging hole portion 216, so that the engaging rod 32 cannot extend and move along the axial direction of the engaging rod 32 , To reduce the resonance of the sound element and avoid abnormal sound.

In summary, the sound emitting device 3 is mounted on the mounting surface 11 of the display body 1 in a snap-fit manner through the fixing structure 2, so that the purpose of mounting without using screws can be achieved. In addition, the installation method of the sounding device 3 is by pushing the engaging rod 32 of the sounding device 3 from the insertion side edge 211 through the limiting hole 215 to be embedded in the engaging hole 216, so that the installation can be achieved. Simple and convenient purpose. In addition, since the aperture D1 of the limiting hole portion is smaller than the diameter D3 of the thin rod portion, and the inverted walls 22 are arranged on the insertion side edge 211 and extend obliquely with respect to the support wall 21, the connecting rod 32 is The thin rod portion 321 is blocked by the hole wall of the limiting hole portion 215, and the first thick rod portion 322 of the adapter rod 32 is restricted to a certain extent by the undercut walls 22, resulting in the adapter rod 32 being The buckle groove 212 cannot be easily separated under the action of external force, so the purpose of stable installation can be achieved. It is worth mentioning that since the diameter D4 of the first thick rod and the diameter D5 of the second thick rod are both larger than the diameter D2 of the connecting hole of the supporting wall 21, the first thick rod 322 and the second thick rod 322 The thick rod portion 323 is blocked by the supporting wall 21 and cannot extend through the engaging hole portion 216 along the axial direction of the engaging rod 32, which can also achieve the purpose of stable installation, and thus can indeed achieve the objective of the invention.
