Description

A twistable and adjustable clip-on earphone

Technical field:

The utility model relates to the technical field of clip-on earphones, in particular to a twistable and adjustable clip-on earphone.

Background technology:

With the development of headphone technology, various types of headphones such as bone conduction, in-ear, semi-in-ear, and head-mounted headphones have emerged in an endless stream, providing headphone users with diverse choices. At the same time, they also have their own advantages and disadvantages. Many users are not used to the pressure of in-ear and head-mounted headphones, and the wearing stability of semi-in-ear headphones is relatively insufficient. Therefore, clip-on headphones have gradually appeared in the users' field of vision. Clip-on headphones are clamped on the auricle through their own structure, and do not need to be inserted into the ear canal, so they will not cause a sense of pressure. In addition, they have attracted a large number of users with their stylish appearance and good playability, and have become a very popular Bluetooth headset in recent years.

The most common clip-on earphones on the market generally use a U-shaped elastic connection part to complete the clamping. Two relatively large ends are respectively arranged at both ends of the elastic connection part, and a sound unit and a circuit unit are respectively arranged in the ends. The two ends are elastically opened and closed by the elastic connection part, so as to facilitate clamping at the position of the human auricle. For example, the Chinese utility model patent with patent announcement number CN219780339U discloses an ear clip type Bluetooth headset, which includes: an elastic connection part, a first extrusion part and a second extrusion part; the two ends of the elastic connection part are respectively connected to the first extrusion part and the second extrusion part, and the elastic connection part is arched in an arc so that the outer contour curves of the first extrusion part and the second extrusion part are close to each other to form a curved shape; the elastic connection part is deformed by external force to adapt to the auricle and attach to the auricle; a speaker assembly is arranged in the first extrusion part, and a sound outlet is arranged on the first extrusion part. When worn, the first squeeze ear clip type pressing part is located in the ear cavity, and the second extrusion part is located at the intersection of the back side of the earlobe and the human head.

However, this existing ear clip type Bluetooth headset has the following shortcomings due to its own structural characteristics:

1. The wearing method is as follows: the elastic connection part is deformed by external force to adapt to the auricle and adhere to the auricle. The elasticity of the elastic connection part is not adjustable. Due to the differences in human bodies, the size of each person's auricle is different, which causes some users to feel discomfort in the auricle when wearing it, affecting the user experience;

2. Since it is difficult to ensure uniform force when manually opening and closing the earphones, the angle of the elastic connection will be different each time. Over time, the earphones will be more deformed and even have the risk of cracking.

In view of this, the inventor proposes the following technical solution.
