Description

Technical Field

[0001] This utility model relates to the field of Bluetooth headset technology, and in particular to a snap-on Bluetooth headset shell. Background Technology

[0002] Bluetooth earphones are popular due to their convenience and compact size, and their use is becoming increasingly widespread. However, prolonged use can easily damage the ears. Users need to be mindful of volume and usage time, and wearing earphones while walking or cycling can obstruct hearing. To address these issues, clip-on Bluetooth earphones have emerged. However, existing clip-on Bluetooth earphones have limitations in their structural design, particularly in the molding process and structural design of the outer shell. These limitations often fail to meet users' needs for comfort and a snug fit. Most existing clip-on Bluetooth earphones use a single molding process, resulting in a lack of flexibility and adjustability in the outer shell. This prevents the earphones from being personalized to the user's ear shape, leading to issues such as a clamp that is too loose or too tight.

[0003] Chinese Patent Application Publication No. CN213522330U discloses a wireless Bluetooth earphone shell, including a main structure. The main structure includes a set of earphone shells. The front end of the earphone shell is provided with a charging pad and a sound-transmitting hole. A waterproof membrane is provided at the sound-transmitting hole. The surface of the earphone shell is coated with an anti-scratch coating. The earphone shell is provided with an outwardly extending connector. The connector is a hollow cylindrical structure. A secondary Bluetooth module and a vibration module are provided inside the connector. The outer surface of the connector is coated with a luminous coating. The outer side of the connector is provided with an embedded groove and a magnetic component. The magnetic component is glued to the connector. When not in use, the left and right earphones can be magnetically attached together. The anti-scratch coating on the surface of the earphone shell can effectively prevent the earphone shell from being scratched by external forces and affecting its appearance. The surface of the earphone shell is also coated with an anti-fingerprint coating to prevent fingerprints from sticking to the surface of the earphone shell. However, the existing technology has the following problems: the existing technology mostly sets the supporting parts on both sides into a semi-circular shape to support the ears, and the tightness of the support is only controlled by a preset elastic part, which cannot be adjusted according to the actual size of the user's ears, resulting in the problem of poor fit of Bluetooth headphones. Utility Model Content

[0004] Therefore, this utility model provides a fit-fitting clip-on Bluetooth earphone shell to overcome the problem in the prior art that the earphone cannot be adjusted according to the actual size of the user's ear, resulting in poor fit of the Bluetooth earphone.

[0021] Furthermore, this invention features a sliding connection that facilitates adjustment of the ear clip width to accommodate different ear shapes.

[0022] Furthermore, this utility model ensures that the adjusting clip can be firmly fixed after adjustment by setting a snap-fit, preventing loosening.

[0023] Furthermore, this invention utilizes a second spring to enable the locking lever to automatically reset, ensuring smooth fixing and releasing of the adjusting clamp.

[0024] Furthermore, by incorporating an arc-shaped steel plate and elastic materials, this invention ensures structural strength while increasing the flexibility and comfort of clamping.

[0025] Furthermore, by setting the elastic force of the second spring to be less than that of the first spring, this utility model ensures that the lever can retract first when the button is pressed, allowing the adjusting clip to slide freely.

[0026] Furthermore, by setting a sloping groove, this utility model enables the locking rod to automatically retract or extend as the adjusting rod moves, thereby realizing the locking and unlocking functions of the adjusting clamp. Attached Figure Description
