Description

A combination earphone

technical field

The utility model belongs to a walkman accessory device, in particular to a combined earphone.

Background technique

With the increasing pressure of modern people's life, work and study, the best way to relieve tension and relax is to listen to a piece of beautiful and beautiful music. Therefore, the popularization of portable audio-visual equipment such as MP3 and MP4 and mobile phones has provided people with It is very convenient, and the earphone has become one of the indispensable accessories as a matter of course. It is chosen by the young friends who love music and learning. However, if the traditional earphone only needs one ear to listen, the other earphone will hang. In mid-air, it hinders other activities and is easily damaged; in addition, the wires of the two earphones are easily entangled with each other after being placed in the bag, preventing reuse.

Utility model content

In order to overcome the deficiencies of the prior art, the utility model provides a combined earphone, which can not only connect the left earphone and the right earphone more firmly and reliably, but also be easy to disassemble, simple in structure and easy to use. convenient.

In order to achieve the above object, the utility model adopts the following technical solutions:

A combined earphone, comprising a left earphone and a right earphone, the tail of one of the left earphone and the right earphone is provided with an external connecting thread, and the tail of the other is provided with a nut matching the external connecting thread. The above-mentioned nut can be freely rotatably fixed on the tail of the earphone.

Preferably, the tail of the earphone provided with the external connection thread is provided with a groove for connection, and the tail of the earphone provided with a nut is provided with a protrusion corresponding to the groove; the nut is sleeved on the root of the protrusion, And the nut can be freely rotatably arranged on the tail of the earphone around the root of the projection.

Further, when the groove is connected with the protrusion, an interference fit is formed.

Further, a retaining ring is provided on the protrusion to block movement of the nut along the length direction of the retaining ring.

Further, the groove is in the shape of a square, and the protrusion is in the shape of a cylinder.

1), the utility model is provided with an external connection thread at the tail of one of the earphones, and a nut that is compatible with the external connection thread is provided at the tail of the other earphone. When it is necessary to connect and fix the two earphones, only the The nut is screwed and sleeved on the external connecting thread to connect the left and right earphones. Due to the thread connection method, the connection and cooperation of the left and right earphones are relatively reliable and firm, and will not be separated due to the impact of external forces. When it is necessary to store the earphones, the left and right earphones can be connected to each other only by turning the nut, which reduces or even avoids the problem of entanglement. The utility model mainly solves the problems that the earphone is easily damaged when listening to one ear and the earphone wire is entangled when being stored, and has a simple structure and reliable and stable application.

2), the utility model is also provided with a square groove for connection on the earphone provided with the external connecting thread, and a cylindrical protrusion for connection is added to the tail of the other earphone corresponding to it. The diameter of the cylindrical protrusion is consistent with the side length of the square groove, and an interference fit is formed when the cylindrical protrusion is connected with the square groove. The nut is sheathed on the root of the cylindrical protrusion and can freely rotate around the root of the cylindrical protrusion.

When the user needs to simply connect the left and right earphones without worrying about falling off, the cylindrical protrusion can be aligned with the center of the square groove, and the left and right earphones can be combined after lightly pressing firmly. The connection threads and nuts will not affect the connection between the protrusion and the groove; when it is necessary to disengage, pull it out with light force to separate the combined earphones again. When the user needs to firmly connect the left and right earphones because they are worried about falling off, they can first connect the earphones through the above-mentioned simple combination method, and then tighten the nut on the right earphone to the end. At this time, the left and right earphones are connected by threads to form a The firm combination will not fall off even if it is impacted by a large external force.

3) Due to the different structures of the tails of the earphones, the utility model also enables the wearer to easily distinguish the left and right earphones. If the left earphone is provided with external connecting threads and grooves, and the right earphone is provided with nuts and bumps, when you need to quickly distinguish the left and right of the earphones, you can touch the tail of the earphones while picking up the earphones. If the groove is left earphone, if the touch is a nut or bump it is the right earphone. Distinguishing the left and right earphones by touch can effectively reduce the resolution time, and it is also more convenient for wearers with poor eyesight to operate.

4) The utility model can meet the various needs of users, and can be combined simply or firmly. The design is more humanized and has great application value.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example.

As shown in Figures 1 and 2, it is a combined earphone, including a left earphone 1 and a right earphone 2. The bump 20 corresponding to the groove 10, the groove 10 and the bump 20 form an interference fit; the tail of the left earphone 1 is also provided with an external connecting thread 11, and the bump 20 at the tail of the right earphone 2 is correspondingly provided with a nut 21 , the left earphone 1 and the right earphone 2 cooperate to form a threaded connection; the nut 21 is fixed on the tail of the right earphone 2 around the protrusion 20 and is freely rotatable.

The groove 10 is set as a square, and the protrusion 20 is set as a circle. The diameter of the cylindrical protrusion 20 is consistent with the side length of the square groove 10. When the cylindrical protrusion 20 is connected with the square groove 10, an interference fit is formed. .

Referring to FIG. 3 , the protrusion 20 is provided with an annular retaining ring 22 , and the outer diameter of the retaining ring 22 is larger than the aperture of the nut 21 . The retaining ring enables the nut 21 to be freely rotatably fixed around the protrusion 20 on the right earphone. 2 tails without shedding.
