Description

Technical Field

[0001] The present invention relates to the technical field of earphones, and particularly to ear-hook type wireless earphones.

Background Art

[0002] With the rapid development of the smart wearable industry, the diversity of earphones has become increasingly rich, and the differentiated needs of users for products are increasing. Along with the development of earphone products, the time that can be used for a single charge of the product is also getting longer and longer, and the need for users to wear the product more conveniently and comfortably for a long time is also getting stronger.

[0003] Ear-hook type earphones are fixed to the ear in the form of ear clips, can be worn for a long time, do not enter the inside of the ear canal, ensure the perception of the environment, and reduce the breeding of bacteria in the ear canal.

[0004] The "bridge" connecting the waist between the front and rear two modules of the conventional ear-hook type earphones can be roughly divided into two types. 1) It is connected by a rigid material and cannot be deformed / can be slightly deformed. Such a design cannot be fixed to the ear without applying force and expanding when wearing, the user experience is relatively poor, and the wearing difficulty is large. 2) It is connected by a memory wire. After being used for a long time, such a design faces the risk that the deformation recovery ability of the memory wire becomes weak and it cannot be easily reset. Summarizing the "bridge" in the above two forms, due to the different ear thicknesses of users, loosening or excessive tightening may occur when wearing. And when in the wearing state, the surfaces where the front and rear two modules of the ear-hook type earphones contact the ear are both rigid contact surfaces, there is no buffer space, and the wearing comfort is poor.

[0005] Referring to Patent Document CN117857971A, it discloses an over-ear Bluetooth earphone, which includes an earphone head, and further includes an ear hook, the ear hook having a mounting groove formed in the inner wall of the ear hook and an earback clip fixedly connected to one end of the ear hook away from the earphone head, a bonding mechanism located on the inside of the ear hook, and a synchronization mechanism located between the bonding mechanism and the ear hook, the over-ear Bluetooth earphone having an air cushion column that inflates to fit and fill the gap between the airbag cushion and the user's auricle, having the same bonding effect when used by users with different auricle shapes, and improving the stability of the fit. However, the over-ear Bluetooth earphone does not have an airbag pad placed on the earphone head and still cannot solve the technical problems that exist in the above-mentioned conventional over-ear earphones.

Modes for Carrying Out the Invention

[0022] The structural principle and operating principle of the present invention will be described in more detail with reference to the following drawings.

[0023] As shown in FIGS. 1 to 5, the present invention is an ear-hanging type wireless earphone including a first earphone head 1, a second earphone head 2, and a bridge portion 3. The bridge portion 3 is connected between the first earphone head 1 and the second earphone head 2. A first airbag 11 is provided in the first earphone head 1, a second airbag 21 is provided in the second earphone head 2, and the positions of the first airbag 11 and the second airbag 21 are opposed to each other. As shown in FIG. 2, it is a view showing a state in which the first airbag 11 and the second airbag 21 are crushed after being pressed against the ear in a wearing state of the ear-hanging type wireless earphone, and the pressure of the ear-hanging product on the ear is reduced or dispersed by the crushing of the first airbag 11 and the second airbag 21.

[0024] In this invention, whether the bridge portion 3 is made of a rigid material or a flexible material, when the ear-hook type wireless earphones are worn, the first airbag 11 and the second airbag 21 always form a cushioning space on the surface that contacts the ear, ensuring stable wearing of the earphones and making the wearing operation more convenient, significantly improving wearing comfort. The first airbag 11 and the second airbag 21 can provide a large angle of rotation to the first earphone head 1 and the second earphone head 2 through a method of compression deformation, providing convenience for the user to wear the earphones and enabling easy one-handed wearing, solving the problem in conventional products of the same type that are difficult to wear with one hand. By applying airbag design to the product, a large angle of rotation can be provided to the first earphone head 1 and the second earphone head 2 through a method of compression deformation, providing convenience for the user to wear the earphones. In this invention, the first airbag 11 and the second airbag 21 are capable of rebounding and collapsing. After collapse, the gap between the first earphone head 1 and the second earphone head 2 becomes larger, making them easier to wear.
