Abstract
The utility model discloses a kind of headphone protecgulum, including housing, the first air-vent and adjusting ring, first air-vent is rounded to be uniformly distributed in housing exterior walls survey, the adjusting ring is shaped as Bifilar hollow circle, the adjusting ring is rounded to be evenly distributed with the second air-vent, the adjusting ring is rotatable to be covered on the first air-vent, and second air-vent is overlapped with the first air-vent at a certain position, changes the gas output of the first air-vent by rotating adjusting ring.By setting up adjusting ring, adjusting ring revolving coverage method can be adjusted the Air permenbility of the first air-vent, change low frequency amount, be adjusted to the sense of hearing of user preferences on the first air-vent by rotating adjusting ring.
Description
Technical field
The utility model is related to a kind of headphone protecgulum.
Background technology
The protecgulum of existing traditional headphone is closed or permeability type, and the how many of Air permenbility are that fixation is unadjustable, are worn
Protecgulum, ear muff and head form a relative confined space after band earphone, when Loudspeaker diaphragm shakes, in vibrating diaphragm driving confined space it
Air capacity is relatively fixed, and air enters back cavity by air-vent in confined space, and the total air of vibrating diaphragm driving can not change, people
The low frequency amount that ear is heard is relatively fixed, it is impossible to suit user preferences regulation.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of headphone protecgulum, by setting up adjusting ring, adjusts
Pitch circle revolving coverage method can be adjusted the Air permenbility of the first air-vent, change low frequency on the first air-vent by rotating adjusting ring
Amount, is adjusted to the sense of hearing of user preferences.
In order to solve the above technical problems, the technical scheme that the utility model is used is：A kind of headphone protecgulum, bag
Housing, the first air-vent and adjusting ring are included, first air-vent is rounded to be uniformly distributed in housing exterior walls survey, the adjusting ring
Bifilar hollow circle is shaped as, the adjusting ring is rounded to be evenly distributed with the second air-vent, and the adjusting ring is rotatable to be covered in
On first air-vent, and second air-vent is overlapped with the first air-vent at a certain position, is changed by rotating adjusting ring
Become the gas output of the first air-vent.
The beneficial effects of the utility model are：Be different from the situation of prior art, the utility model by setting up adjusting ring,
Adjusting ring revolving coverage method can be adjusted the Air permenbility of the first air-vent, change low frequency on the first air-vent by rotating adjusting ring
Amount, is adjusted to the sense of hearing of user preferences.

Embodiment
For the ease of understanding the utility model, with reference to the accompanying drawings and detailed description, the utility model is carried out more
Detailed description.It should be noted that when element is expressed " being fixed on " another element, it can be directly in another element
There may be above or therebetween one or more elements placed in the middle.When an element is expressed " connection " another element, it can
To be directly to another element or there may be one or more elements placed in the middle therebetween.This specification is used
Term " vertical ", " level ", "left", "right" and similar statement for illustrative purposes only.
Unless otherwise defined, technology all used in this specification and scientific terminology are with belonging to skill of the present utility model
The implication that the technical staff in art field is generally understood that is identical.In art used in the description of the present utility model in this specification
Language is intended merely to describe the purpose of specific embodiment, is not intended to limit the utility model.Art used in this specification
Language "and/or" includes the arbitrary and all combination of one or more related Listed Items.
Referring to Fig. 1 to Fig. 5, the utility model provides a kind of headphone protecgulum, including housing 11, the and of the first air-vent 12
Adjusting ring 13, the rounded outer wall of housing 11 that is uniformly distributed in of the first air-vent 12 is surveyed, and adjusting ring 13 is shaped as Bifilar hollow circle,
Adjusting ring 13 is rounded to be evenly distributed with the second air-vent 131, and adjusting ring 13 is rotatable to be covered on the first air-vent 12, and
Second air-vent 131 is overlapped with the first air-vent 12 at a certain position, and the first air-vent 12 is changed by rotating adjusting ring 13
Gas output.In Fig. 1, it is relative that the Air permenbility of the first air-vent 12 only has protecgulum after 1/3, wearing headphones, ear muff and head to form one
Confined space, when Loudspeaker diaphragm shakes, the air in confined space can enter back cavity by the first air-vent 12, vibrating diaphragm driving
Air capacity accordingly increases, and is reduced when the low frequency amount that human ear is heard is relative to using closed protecgulum, adjusting ring of the present utility model
It is rotatable, be the full impregnated of the first air-vent 12 and full closeding state respectively as shown in Figure 4 and Figure 5, user can according to personal like,
Adjusting ring 13 is rotated, arbitrarily regulation first is breathed freely, 12 Air permenbility, to adjust low frequency amount, suit the personal sense of hearing liked, it is non-
It is often convenient and practical, it is simple in construction.
The utility model is mainly solving the technical problems that provide a kind of headphone protecgulum, by setting up adjusting ring 13,
The revolving coverage method of adjusting ring 13 can adjust the Air permenbility of the first air-vent 12 on the first air-vent 12 by rotating adjusting ring 13,
Change low frequency amount, be adjusted to the sense of hearing of user preferences.
Of the present utility model preferably implement it should be noted that being given in specification of the present utility model and its accompanying drawing
Mode, still, the utility model can be realized by many different forms, however it is not limited to the implementation described by this specification
Mode, these embodiments are to make there is provided the purpose of these embodiments not as the extra limitation to the utility model content
