[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] The present utility model provides an in-ear headphone with a switchable Bluetooth and wired coil and iron structure, as Figures 1 - 4 shown, including a housing 1, a cover plate 2 is installed on the top of the housing 1, a cavity is provided inside the housing 1 and a circuit board 3, an armature unit 4 and a moving coil unit 5 are installed in sequence, a sound outlet 12 is installed at the bottom of the housing 1, an inlet 13 is provided on one side of the housing 1, a circuit is connected to the outside of the inlet 13, and the circuit is electrically connected to the input point of the circuit board 3. A circuit board installation groove 14 is provided inside the housing 1, and the circuit board 3 is arranged inside the circuit board installation groove 14 to facilitate the placement and limitation of each component.
[0024] In this embodiment, the inlet 13 is sealed by a sealing plug during wiring to prevent dust from entering.
[0025] Specifically, an installation opening 11 is provided at the top of the housing 1, and the cover plate 2 is buckled at the installation opening 11 to facilitate the opening and closing of the housing 1.
[0026] Furthermore, an armature unit installation groove 15 is provided inside the housing 1, the armature unit 4 is arranged inside the armature unit installation groove 15, a first sound transmission channel 151 is provided at the bottom of the armature unit installation groove 15, and the front of the armature unit 4 is in contact with the first sound transmission channel 151 to facilitate the outward transmission of sound.
[0027] Furthermore, an inner side of the housing 1 is provided with a moving coil unit mounting groove 16, the moving coil unit 5 is disposed inside the moving coil unit mounting groove 16, a bottom of the moving coil unit mounting groove 16 is provided with a second sound transmission channel 161, and a front surface of the moving coil unit 5 is in contact with the second sound transmission channel 161, facilitating outward transmission of sound.
