7. The earphone of claim 1 , wherein the core module further comprises a core bracket disposed in the core housing, and the coil is fixed on the core bracket.
8. The earphone of claim 1 , wherein the magnetic gap between the magnet and the annular side plate is in a range of 1.0 mm-1.5 mm.
9. The earphone of claim 1 , further comprising an ear hook assembly, one end of the ear hook assembly being connected to the core module.
10. The earphone of claim 9 , wherein the ear hook assembly comprises an ear hook housing, the ear hook housing including:
an accommodation bin configured to accommodate a battery or a main control circuit board;
a fixing portion covered on an opening end of the core housing to form a chamber for accommodating the core; and
a bending transition portion, the bending transition portion connecting the accommodation bin and the fixing portion, and being disposed in a bent shape to be hung on an outside of an ear of the user.
11. The earphone of claim 10 , wherein an elastic modulus of the core housing is larger than an elastic modulus of the ear hook housing.
12. The earphone of claim 10 , wherein the fixing portion is disposed with a reinforcing structure, a ratio of a difference between a rigidity of the bottom wall and a rigidity of the fixing portion and the rigidity of the bottom wall being less than or equal to a preset ratio threshold.
13. The earphone of claim 12 , wherein the reinforcing structure comprises a reinforcing rib disposed on the fixing portion, and a material of the reinforcing structure includes a metal piece, wherein the reinforcing structure and the fixing portion of the earphone are integrally formed by metal insert injection molding.
14. The earphone of claim 10 , wherein the core module further comprises a cover plate, the cover plate being covered on the opening of the annular peripheral wall of the core housing, and the fixing portion being covered on one side of the cover plate that is away from the core housing.
15. The earphone of claim 14 , wherein an elastic modulus of the cover plate is larger than an elastic modulus of the ear hook housing and less than or equal to an elastic modulus of the core housing.
16. The earphone of claim 10 , wherein the ear hook assembly further comprises a decoration bracket, wherein:
a first groove is disposed on the bending transition portion, the decoration bracket is embedded and fixed in the first groove to form a wiring channel such that a wire extends from the core module into the accommodation bin through the wire channel.
17. The earphone of claim 16 , wherein
a button adaptation hole is disposed on the fixing portion of the earphone, and the button adaptation hole is in communication with one end of the first groove; and
the ear hook assembly further includes a button, the button being disposed on the other side of the ear hook housing that is away from the decoration bracket, and exposed through the button adaptation hole.
18. The earphone of claim 17 , wherein
the decoration bracket extends to a top of the button in a form of cantilever and is able to trigger the button when pressed by an external force, the button being exposed through the button adaptation hole.
19. The earphone of claim 9 , wherein the earphone includes two core modules, magnets of the two core modules having different polarities on one side close to the bottom wall of the core housing, when the earphone is in a non-wearing state, the two core modules being attractable to each other.
20. The earphone of claim 19 , wherein the earphone includes two ear hook assemblies and a rear hook assembly configured to circumferentially disposed at a rear side of the user's head, and two ends of the rear hook assembly are respectively connected with accommodation bins of the two ear hook assemblies.
