Title: BLUETOOTH EARPHONE
Abstract:
A Bluetooth earphone comprising an earphone body (100), a connector (200) and an earmuff (300), wherein the earphone body (100) is provided with a joint (101), a positioning rib (102) is provided to be matched with a peripheral surface of the joint (101), a positioning groove (103) is provided around a peripheral surface of the positioning rib (102), a snap-in opening (104) is formed between the end of the positioning groove (103) and the joint (101), the connector (200) is provided with a positioning protrusion (201), and the positioning protrusion (201) can be inserted into the snap-in opening (104) and slides along the positioning groove (103) in a guiding manner. During the removal or fitting of the earmuff (300) by a user as required, only a rotational force needs to be applied to the earmuff (300), thereby facilitating the user in replacing or fitting the earmuff (300) and thus improving the efficiency of the removal or fitting of the earmuff (300) by the user. Moreover, the Bluetooth earphone can achieve two-level acoustic and audio sealing, and the design of the two-level acoustic and audio sealing enables the acoustic and audio sealing effect to be more reliable.
