the connecting part includes a first wire clamping part used to restrict a set of lead wires drawn out from the speaker assembly and extending into the accommodating space, the set of lead wires electrically connect the speaker assembly to the battery assembly and/or the control circuit, the first wire clamping part fixes the set of lead wires in a radial direction of the set of lead wires, the first wire clamping part has a first lead wire channel, and the set of lead wires drawn out from the speaker assembly enters the accommodating space through the first lead wire channel; and
the ear hook housing includes a second wire clamping part used to fix the set of lead wires in the radial direction of the set of lead wires, the second wire clamping part has a second lead wire channel, and the set of lead wires drawn out from the speaker assembly enters the accommodating space through the first lead wire channel and the second lead wire channel in sequence.

2. The acoustic output apparatus of claim 1 , wherein the connecting part includes an ear hook elastic wire and a joint part connected to one end of the ear hook elastic wire, wherein the joint part is plug-fitted with the speaker assembly, and the other end of the ear hook elastic wire is connected to the ear hook housing.

3. The acoustic output apparatus of claim 1 , wherein the first wire clamping part includes at least two first sub-wire clamping parts arranged at intervals, and the at least two first sub-wire clamping parts form the first lead wire channel in a length direction of the set of lead wires.

4. The acoustic output apparatus of claim 3 , wherein extension lengths of the two first sub-wire clamping parts in the length direction of the set of lead wires are different.

5. The acoustic output apparatus of claim 1 , wherein the second sub-clamping part includes two second sub-wire clamping parts arranged at intervals, and the two second sub-wire clamping parts are opposite to each other and form the second lead wire channel.

6. The acoustic output apparatus of claim 1 , wherein the connecting part includes an ear hook elastic coating, and the ear hook elastic coating wraps a periphery of the ear hook elastic wire, a portion of the joint part, and a portion of the ear hook housing.

7. The acoustic output apparatus of claim 2 , wherein the joint part includes at least two sub-ends, and the at least two sub-ends are located at one end of the joint part that is inserted with the speaker assembly, wherein the at least two sub-ends are spaced apart along a circumferential direction of the end that is inserted with the speaker assembly.

8. The acoustic output apparatus of claim 7 , wherein peripheries of the at least two sub-ends are provided with protrusions, when the joint part is inserted into the speaker assembly, the protrusions are locked and limited by the speaker assembly, so as to restrict the joint part from moving in a direction away from the speaker assembly.

9. The acoustic output apparatus of claim 7 , wherein the speaker assembly includes a first speaker housing, a second speaker housing, a speaker, and a rotating member, the first speaker housing and the second speaker housing are connected to form a containment space for accommodating the speaker, the first speaker housing is provided with a first through hole, the first through hole communicates with the containment space, and the rotating member is rotatably inserted into the first through hole.

10. The acoustic output apparatus of claim 9 , wherein the first speaker housing is provided with a second through hole, the second through hole is spaced apart from the first through hole, the joint part is inserted into the second through hole, protrusions of the joint part are located in the containment space, and the protrusions are clamped on an edge of a connection between the second through hole and the containment space.

11. The acoustic output apparatus of claim 10 , wherein the first speaker housing includes a bottom wall and a side wall connected to each other, the side wall surrounds the bottom wall, the second speaker housing covers on a side of the side wall away from the bottom wall to form the containment space, the first through hole is formed on the bottom wall, and the second through hole is formed on the side wall.

12. The acoustic output apparatus of claim 11 , wherein
the bottom wall includes a first convex part departing from the containment space, and the first through hole is formed in the first convex part;
the side wall includes a second convex part departing from the containment space, and the second through hole is formed in the second convex part;
wherein, a protruding direction of the first convex part and a protruding direction of the second convex part are perpendicular to each other, and the first convex part and the second convex part are connected in an arc shape.

13. The acoustic output apparatus of claim 10 , wherein the apparatus further includes a microphone tube assembly connected to the rotating member, the microphone tube assembly is rotated relative to the first speaker housing by the rotating member, a set of lead wires of the microphone tube assembly passes through the first through hole, and enters into the second through hole through the containment space.

14. The acoustic output apparatus of claim 13 , wherein
the rotating member includes a lead part and a rotating part connected to each other, the lead part is formed with a first hole segment, the rotating part is formed with a second hole segment along an axial direction of the rotating part, and the first hole segment is communicated with the second hole segment;
the speaker assembly includes a fixing member, the fixing member includes a fixing body and a plug pin arranged at one end of the fixing body, the fixing body is inserted into the second hole segment, and the plug pin is inserted into a fixing hole to limit a movement of the microphone tube assembly.

15.
