With the advent of true wireless headsets (TWS), headsets were freed from the constraints of the wiring harness, greatly improving portability and comfort of use. Wireless headsets can be broadly divided into two categories: active noise reduction wireless earphones and passive noise reduction wireless earphones. The active noise reduction wireless earphone can bring more immersive music listening experience for a user, and soft silica gel is required to be filled in an auricle (in-ear type) as far as possible to achieve a better noise reduction effect. But wear for a long time and can bring the discomfort and the foreign matter sense of ear for the user, and influence the ear heat dissipation under the hot environment, bring not pleasantly enough and lasting wearing experience for the user. The noise reduction effect of the half-in-ear earphone is far less than that of the in-ear earphone, so that many earphone users can prepare the in-ear earphone and the half-in-ear earphone respectively to meet the requirements of different application scenes, thereby bringing inconvenience to the users. In the correlation technique, the mouthpiece structure of the earphone and the earphone main body are integrally formed to be an integral structure, so that the earphone cannot be disassembled or replaced, and the in-ear type earphone and the half-in-ear type earphone cannot be freely switched as required, thereby bringing inconvenience to users.

Based on the above-mentioned concepts and problems, the present invention provides an earphone 100.

It can be understood that one side of connecting portion 231 back to outer plug portion 233 is protruding to be equipped with annular protruding to enclose with connecting portion 231 and close and form the joint groove, the periphery wall joint of earplug portion 211 in this joint inslot, make the protruding butt of annular spacing in the butt joint platform that the junction of earplug portion 211 and grafting portion 212 formed.

In an embodiment, as shown in fig. 2, 3, 5, and 6, a limiting platform 2111 is disposed on a side of the earplug portion 211 facing away from the inserting portion 212, the limiting platform 2111 is disposed around the sound outlet channel 213, and the dust screen 22 is limited at the limiting platform 2111 to cover the sound outlet channel 213.

It will be appreciated that the dust screen 22 may be attached to the retention stage 2111 of the earplug portion 211 by bonding, welding, injection molding, or the like. The dust screen 22 has a plurality of sound transmission holes to facilitate sound to pass through the sound transmission holes of the dust screen 22 into the user's ears. Alternatively, the dust screen 22 may be made of metal mesh, plastic mesh, gauze, etc., and is not limited herein.

The earphone 100 of the present invention can realize free replacement of the in-ear type mouthpiece structure 2 and the half-in-ear type mouthpiece structure 2. The insertion part 212 of the in-ear mouthpiece structure 2 is directly inserted into the insertion groove 114 of the earphone main body 1, the locking ring 12 in the insertion groove 114 is clamped into the clamping hole 2121 of the insertion part 212 in the mouthpiece 21 by the clamping part 121, so that the in-ear mouthpiece structure 2 and the earphone main body 1 are fixedly mounted, and then the rubber plug 23 is sleeved on the earplug part 211 of the mouthpiece 21, so as to realize the wearing structure of the common in-ear noise reduction earphone 100, as shown in fig. 1 to 3.

When a half-in-ear wearing requirement exists, the earmuff of the soft rubber plug 23 is taken down, the thimble is inserted into the insertion hole 1131 of the earphone shell 11, the thimble pushes the end of the locking ring 12 to deform the end toward the position avoiding hole 1121, so that the clamping portion 121 of the locking ring 12 is separated from the clamping hole 2121 of the sound outlet nozzle 21, the sound outlet nozzle 21 of the in-ear sound nozzle structure 2 is pulled out of the insertion groove 114, the insertion portion 212 of the sound outlet nozzle 21 of the half-in-ear sound nozzle structure 2 is inserted into the insertion groove 114, the locking ring 12 in the insertion groove 114 is clamped into the clamping hole 2121 of the insertion portion 212 in the sound outlet nozzle 21 by the clamping portion 121, so as to realize the installation and fixation of the half-in-ear sound nozzle structure 2 and the earphone main body 1, as shown in fig. 4 to 6, and the structure conversion from the in-ear earphone 100 can be completed. Of course, if the in-ear type mouthpiece structure 2 is continuously replaced, the replacement can be achieved by the same method as described above, and the convenience of use for the user can be improved.

The earphone 100 of the utility model has simple structure, can enable a user to independently select a wearing mode, is easy to switch the structure, can meet the comfortable wearing requirements of different user groups in different using environments, and improves the dependence degree of the user.

It can be understood that simple elastic pieces or rubber pad locking mechanisms similar to mobile phone sim card slots can be utilized to fix the sound mouth structure 2 and the earphone main body 1, and the actions of detaching and replacing the sound mouth structure 2 through the ejector pins can be realized, so that the use convenience is improved.

The utility model further provides a TWS headset, which includes a headset case and the headset 100, and the specific structure of the headset 100 refers to the foregoing embodiments, and since the TWS headset adopts all technical solutions of all the foregoing embodiments, the TWS headset at least has all the beneficial effects brought by the technical solutions of the foregoing embodiments, and details are not repeated herein.

In the present embodiment, the earphone box is provided with a receiving cavity, and the earphone 100 is detachably received in the receiving cavity. It can be understood that the earphone box may be a box body conventionally used for accommodating the earphone 100, and the earphone box may also be a charging box, so as to conveniently realize charging and accommodating functions for the earphone 100, which is not limited herein.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
