The utility model provides a split type dual-purpose earphone, this earphone include bluetooth headset and can dismantle the earphone cord of electricity connection with bluetooth headset. Split type dual-purpose earphone acquires audio data through obtaining with intelligent terminal wireless communication and carries out the audio playback when using as bluetooth headset, acquires audio data through earphone cord and intelligent terminal wired connection and carries out the audio playback when using as traditional wired earphone, and concrete implementation explains through following embodiment:

the first embodiment is as follows:

in the first embodiment, a split dual-purpose headset is provided, as shown in fig. 1 and fig. 2, a bluetooth headset of the dual-purpose headset is a TWS headset 1, and a headset cord 2 detachably and electrically connected to the TWS headset 1.

The TWS headset 1 is provided with a built-in battery module (not shown) therein to supply power to the TWS headset 1 when the TWS headset 1 is separated from the headset cord 2 and operates alone. When the TWS earphone 1 is externally connected with the earphone wire 2, the TWS earphone 1 communicates with the intelligent terminal through the earphone wire 2.

With continued reference to fig. 2, the headset cord 2 includes a left ear branch cord 22 and a right ear branch cord 23 that are correspondingly removably electrically connected to the left ear 12 and the right ear 13 of the TWS headset 1.
