Abstract
The utility model discloses a HEADPHONE, it includes upper cover, lower cover, fan piece, pivot, the fan film jacket is in between the upper and lower lid, the pivot is established upper and lower lid middle part, upper and lower lid is equipped with corresponding fretwork sector, the fretwork sector can the quilt the fan piece covers completely, the side reason of fan piece internal surface is equipped with the batter post form and swells, down inner surface of the cover's side reason be equipped with with protruding corresponding depressed part, the mat surface is made to protruding top face, with the increase protruding with contact friction power between lower inner surface of the cover. This kind of earphone makes the user can independently adjust the external sound size of desiring to hear, and fans the difficult proper motion of piece and rotate.
Description
Technical field
The utility model relates to a kind of earphone, particularly relates to circumaural earphone.
Background technology
201420821406.1 utility model patents disclose a kind of circumaural earphone, comprise earmuff, earmuff is can open or closed open and close type earmuff.Described open and close type earmuff comprises upper cover, lower cover and sealing fan blades, described sealing fan blades is clipped between upper cover and lower cover, described sealing fan blades comprises blade and can make the rotating shaft of blade rotation, described upper cover and the corresponding blade of lower cover are provided with the sector of hollow out, and described rotating shaft is arranged in the middle part of upper cover and lower cover.Although above-mentioned circumaural earphone when external sound heard by needs, by sealing fan blades Unscrew to hear external sound, can not take, rotary closing.But fan blades is easily rotated voluntarily, hear external sound when external sound need not be heard, when external sound need be heard, but can't hear or reduce sound effect.Further, earphone user can not from the external sound size of main regulation for hearing.
Utility model content
Technical problem to be solved in the utility model is the further improvement of the utility model of 201420821406.1 to the patent No., makes earphone user can from the external sound size of main regulation for hearing, and fan blades is not easily rotated voluntarily.
The utility model is the technical scheme solving the problems of the technologies described above employing: a kind of circumaural earphone, described earphone comprises upper cover, lower cover, fan blades, rotating shaft, described fan blades be clipped in described on, between lower cover, described rotating shaft be located at described on, in the middle part of lower cover, on described, under be covered with corresponding hollow out sector, described hollow out sector can be hidden completely by described fan blades, it is characterized in that, the lateral edges of described fan blades inner surface is provided with oblique columnar protrusions, the lateral edges of described lower interior surface is provided with the depressed part corresponding with described projection, described projection top end face is made for matsurface, to increase the contact friction force between described projection and described lower interior surface.
In described circumaural earphone, described projection quantity is two and is all located at the both sides of described fan blades inner surface, and described depressed part quantity is also two and is all located at the both sides of described lower interior surface.
In described circumaural earphone, described projection is made up of elastic soft plastic.
The utility model improves 201420821406.1 circumaural earphone patents, reach following technique effect: earphone user can from the external sound size of main regulation for hearing, and fan blades can not automatic moving, when need not hear any external sound in addition, fan blades also well can stably cover in hollow out sector.
Accompanying drawing explanation
Fig. 1 is the partial schematic diagram of fan blades and lower interior surface in the utility model;
Fig. 2 is external structure schematic diagram of the present utility model.
Embodiment
Be described in further detail the utility model below in conjunction with drawings and Examples: as shown in Fig. 1 to 2, circumaural earphone of the present utility model comprises: projection 1, depressed part 2, projection top end face 3, fan blades 4, lower interior surface 5, lower cover 6, rotating shaft 7, upper cover 8, hollow out sector 9.Described fan blades 4 is clipped between described upper and lower cover, described rotating shaft 6 is located in the middle part of described upper and lower cover, described upper and lower cover is provided with corresponding hollow out sector 9, described hollow out sector 9 can be hidden completely by described fan blades 4, the lateral edges of described fan blades 4 inner surface is provided with oblique columnar protrusions 1, described projection 1 is preferably made up of elastic soft plastic, the lateral edges of described lower interior surface 5 is provided with the depressed part 2 corresponding with described projection 3, described projection top end face 3 is made for matsurface, to increase the contact friction force between described projection 1 and described lower interior surface 5.User is when hearing external sound, and twisting rotating shaft 7 makes fan blades 4 cover in hollow out sector 9, because now projection 1 is stuck in depressed part 2, fan blades 4 can not be rotated voluntarily, improve result of use.When user wants to hear external sound, also be twisting rotating shaft 7, make projection 1 produce depressed part 2 to move on lower interior surface 5, because projection top end face 3 is coarse, increase the contact friction force of projection 1 and lower interior surface 5, make earphone user can be easy to regulate external sound size for hearing, and fan blades also not easily automatic moving, which also improves result of use.The quantity of projection 1 is preferably 2, and be all located at the both sides of described fan blades 4 inner surface, the quantity of depressed part 2 is also preferably 2, and be all located at the both sides of described lower interior surface 5, such rotating shaft 7 clockwise and can be rotated counterclockwise fan blades to regulate the external sound size for hearing, and when fan blades 4 covers hollow out sector 9 completely, two projections 1 are just stuck in two depressed parts 2 on the lower interior surface 5 of both sides, hollow out sector 9, further increase the stability of fan blades 4.
The above introduction of technological means being only embodiment of the present utility model and using, be not to restriction of the present utility model, be all considered as being included within technology category of the present utility model according to disclosure herein and illustrate that any change, the equivalence done is replaced, improvement etc.
Claims (3)
