DETAILED DESCRIPTION

[0023] The following is combined with Figures 1 to 6 The utility model is described in detail.

[0024] The utility model is a high-quality flat-head earphone, comprising an earphone housing 1 and a dynamic unit 2 arranged inside the earphone housing 1, wherein a sound cavity 11 is arranged inside the earphone housing 1, and the dynamic unit 2 divides the sound cavity 11 into a front cavity 12 and a rear cavity 13, and the front cavity 12 is also provided with a first moving iron unit 3; the earphone housing 1 is provided with a sound outlet 14 corresponding to the dynamic unit 2, and the earphone housing 1 is provided with a first sound outlet 15 corresponding to the first moving iron unit 3. The utility model is a flat-head earphone, which is comfortable to wear. When the earphone is working, the dynamic unit 2 and the moving iron unit make sound at the same time and make sound through their own independent sound outlet holes, so that the sound output by the earphone has the advantages of the sound output by the dynamic unit 2 and the moving iron unit, improves the earphone bandwidth, and enhances the response to high-frequency sound. On the basis of meeting the user's wearing comfort requirements, it ensures that the earphone stably outputs high-fidelity sound effects.

[0025] To further improve the technical solution, a second moving iron unit 4 is further provided inside the front cavity 12. Figure 4 As shown, the second moving iron unit 4 is arranged in the front cavity 12 of the earphone opposite to the first moving iron unit 3, further improving the sound effect of the earphone; similarly, the earphone housing 1 is provided with a second sound outlet 16 corresponding to the second moving iron unit 4, and the second sound outlet 16 facilitates the independent sound output of the second moving iron unit 4.

[0026] Preferably, a sound outlet portion 17 is protruded from the front end of the earphone housing 1, and the sound outlet 14, the first sound outlet hole 15 and the second sound outlet hole 16 are all arranged on the sound outlet portion 17. The surface of the sound outlet portion 17 is smooth, which is convenient for processing and forming the sound outlet 14 and the sound outlet holes; in particular, the first sound outlet hole 15 and the second sound outlet hole 16 are symmetrically arranged on both sides of the sound outlet 14. This positional relationship enables the high-frequency sound effects generated by the two moving iron units to surround the low-frequency sound effects generated by the dynamic coil unit 2, and the connection between the low-frequency sound effects and the high-frequency sound effects is further optimized.

[0027] When the utility model is a wired headset, it also includes an audio cable 5, one end of which is provided with an audio connector 51 for connecting to an external electronic device, and the other end of the audio cable 5 is connected to the headset housing 1 and is electrically connected to the dynamic coil unit 2, the first moving iron unit 3 and the second moving iron unit 4 inside the headset housing 1 to realize the transmission of audio signals of the electronic device.

[0028] On the basis of the above-mentioned wired headset technical solution, as a preferred embodiment, the rear cavity 13 is further provided with a connection socket 131, and the earphone housing 1 is provided with a plug hole at a position corresponding to the connection socket 131; the end of the audio cable 5 connected to the earphone housing 1 is provided with a plug 52, and the plug 52 can be plugged into the connection socket 131 through the plug hole. This connection method makes the earphone and the audio cable 5 detachable, and the user can replace the audio cable 5 according to their own needs, which meets the diverse use needs and can effectively reduce the use cost.

[0029] As an embodiment, the earphone housing 1 of the present technical solution includes a front cover 18 and a rear cover 19, which are buckled together to form a sound cavity 11. The earphone housing 1 with a split configuration is more convenient in the manufacturing, assembly and maintenance processes.

[0030] Since the sound outlet 14 has a large opening, a protective net 6 is installed on the sound outlet 14 to prevent external moisture, dust, etc. from easily entering the earphone, thereby extending the service life of the earphone. The protective net 6 can be a steel filter, which has good rigidity, is not easy to fall off, and is more durable.

[0031] In the present technical solution, a first annular boss 181 is extended from the outer wall of the front end cover 18, and the first annular boss 181 and the inner wall of the front end cover 18 form a first platform portion 182; a second annular boss 191 is extended from the inner wall of the rear end cover 19, and the second annular boss 191 and the outer wall of the rear end cover 19 form a second platform portion 192; the first annular boss 181 and the second platform portion 192 are abutted against each other, the second annular boss 191 and the first platform portion 182 correspond to each other, and the outer peripheral side of the dynamic coil unit 2 is fixed between the second annular boss 191 and the first platform portion 182.

[0032] The second annular boss 191 is provided with an elastic notch 193 .
