9. The acoustic input and output apparatus of claim 5 , wherein

the first loudspeaker housing includes a bottom wall and a side wall connecting with each other, and the side wall surrounds and connects with the bottom wall;

the second loudspeaker housing is arranged covering one side of the side wall away from the bottom wall to form the containment space; and

the first through-hole is formed on the bottom wall, and the second through-hole is formed on the sidewall.

10. The acoustic input and output apparatus of claim 9 , wherein

the bottom wall includes a first convex part protruding in a direction deviate from the containment space, and the first through-hole is formed on the first convex part, and

the side wall includes a second convex part protruding in a direction deviate from the containment space, and the second through-hole is formed on the second convex part.

11. The acoustic input and output apparatus of claim 5 , wherein the sound-pickup assembly is rotatable relative to the loudspeaker assembly.

12. The acoustic input and output apparatus of claim 11 , wherein the connection assembly further includes a rotation member matched and connected to the first through-hole rotatably, and the sound-pickup assembly is connected with the rotation member so as to rotate relative to the first loudspeaker housing.

13. The acoustic input and output apparatus of claim 5 , wherein

the at least one ear hook assembly includes an ear hook connection assembly and an ear hook housing;

the ear hook assembly is connected with the second through-hole and the ear hook housing, and the ear hook housing is configured with an accommodating space for accommodating at least one of a battery assembly or a control circuit assembly; and

the wiring group of the sound-pickup assembly passes through the second through-hole and enters the accommodating space via the ear hook connection assembly.

14. The acoustic input and output apparatus of claim 13 , wherein the ear hook housing includes a first ear hook housing and a second ear hook housing matching the first ear hook housing, and the accommodating space is formed when the first ear hook housing is connected with the second ear hook housing.

15. The acoustic input and output apparatus of claim 13 , wherein the ear hook assembly includes a splicing assembly configured to restrict a movement of the first ear hook housing and the second ear hook housing in a splicing direction and a thickness direction.
