Description
Technical field
The utility model relates to a kind of earphones.
Background technique
Old money without headband cross line earphone need it is bilateral enter line, as shown in Figure 1, wear comfort it is not good enough, wire rod needs to be stuck in neck
Under son, the size of head and the length of the neck that can be affected are brought and its inconvenient wearing and can not in external form to user
Have breakthrough
It is the head dummy size for adapting to different user at general earphone bracket, regulating mechanism can have been designed, this requires conducting wires
It wants regulating mechanism can be followed accordingly to stretch here.
Traditional method is all to allow conducting wire to do U-shaped revolution in rack bore position or Z-type is flexible, thus bracket must have compared with
Wide space.Also the entire external form of larger seems and entirely wears the service life of stretching in 3000-5000 than cumbersome the volume of bracket
It is secondary, cause to stretch service life short
Utility model content
In order to solve the problems, such as background technique, the utility model provides a kind of extension spring-type headband and crosses line earphone,
The both ends of head-wearing wire are provided with spring ring, so that the earphone has many advantages, such as small and beautiful, the pull service life is long.
The utility model adopts the following technical solution:
A kind of extension spring-type headband crosses line earphone, including headband bracket and headgear assembly, and the telescopic setting of headgear assembly exists
The both ends of headband bracket, which is characterized in that head-wearing wire is provided in headband bracket, head-wearing wire from the beginning stretch out by belt supporting frame both ends, head
Part with line stretched head belt supporting frame is provided with spring ring.
The headgear assembly has the telescopic sleeve stretched out upwards, and telescopic pipe sleeve stretches at the both ends in headband bracket
Casing can be with respect to headband bracket slide.
The spring ring after head-wearing wire coiling and molding by obtaining.
The diameter of the head-wearing wire is 1mm, and the outer diameter of spring ring is less than 5mm.
The circle number of the spring ring is 12-14 circle.
The beneficial effects of the utility model are:
1) entire earphone configuration design is unrestricted；
2) volume and shape can be with more compact beauties；
3) the headband pull service life is greatly improved, it is ensured that the service life of earphone.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawing
Fig. 1 is Headphone structure schematic diagram in the prior art；
Fig. 2 is the structural schematic diagram of earphone described in the utility model；
Fig. 3 is the structural schematic diagram of head-wearing wire in Fig. 2；
