Taking the vibration direction of the diaphragm as the height direction of the sounding unit 311, generally in order to ensure the loudness of the sounding unit 311, the diaphragm needs to be large enough. The size of the diaphragm determines the length and width of the sounding unit 311, so that the The sound-generating unit 311 is a rectangular parallelepiped or a cylinder whose length and width are much larger than its height. The sounding module 31d is assembled into the inner cavity 12 through the second assembly port 16 in a direction parallel to the plane where the diaphragm is located, so that when the sounding unit 311 is assembled, the sounding unit 311 can be assembled in a direction parallel to the plane where the diaphragm is located into the accommodating space, so that the size of the second assembly port 16 only needs to be adapted to a certain side wall of the sounding unit 311 , which reduces the size of the second assembly port 16 .

When multiple functional units 3 need to be placed in the inner cavity 12 at the same time, a limit structure can also be set to limit the position of each functional unit 3, so as to ensure that after each functional unit 3 is placed in the inner cavity 12, by pushing Or the pull can stop at the preset installation position.

In the embodiment shown in FIG. 9 , the deformation sleeve 313 only covers the side wall of the sounding unit 311 , so that the diaphragm is exposed from an opening of the deformation sleeve 313 . In order to ensure a stable positional relationship between the temple shell 1 and the deformation sleeve 313, the structure and size of the deformation sleeve 313 are adapted to the inner cavity 12 of the temple shell 1, so that the deformation sleeve 313 can directly pass through the second assembly port 16, and at the same time The interference is fixed in the temple shell 1. The size of the second assembly opening 16 is matched with the deformation sleeve 313 , so that the second assembly opening 16 is small enough to improve the consistency of the appearance of the temple structure 10 .

Please refer to FIG. 10 , a sounding front cavity 312 is formed between the diaphragm and the second side wall 13 , and the temple structure 10 further includes a second decorative cover 93 covered on the second assembly opening 16 .

By orienting the diaphragm of the sound-generating unit 311 toward the inner side wall, the sound of the sound-generating unit 311 is closer to the user, and the vibration and sound of the diaphragm can be effectively transmitted to the user. By opening the second assembly opening 16 on the bottom side wall, when the user wears the temple structure 10 , the sealing cover can be hidden, and the exposed appearance is consistent. At the same time, the sound-generating unit 311 and the third side wall located opposite to the second side wall 13 form a sound-emitting rear cavity 314, and the temple shell 1 can also be provided with a sound vent 316 that communicates with the sound-emitting rear cavity, so that the sound-generating unit can The air pressure inside 311 is the same as the outside.
