Description
Technical field
The utility model relates to a kind of loudspeaker, in particular to a kind of earphone horn shell with air hole.
Background technique
It is generally headset assembly inside earphone, when headset assembly use can generate vibration, and due to being electronic building brick, make
Used time can generate heat, and in order to increase gas permeability, we can be arranged air hole on shell, but earphone is due to being electronic product, if
Setting air hole can make waterproof performance be deteriorated later, and external moisture can pass through air hole and enter enclosure interior, to internal ear
Thermomechanical components cause electric effect, although therefore open up air hole and can achieve the purpose that ventilative, waterproof performance will be greatly reduced.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of earphone horn shell with air hole, with saturating
The earphone horn shell of stomata, can guarantee gas permeability when in use, can guarantee leakproofness when not in use.
The utility model is achieved through the following technical solutions: a kind of earphone horn shell with air hole, packet
Headset main body is included, which includes outer housing and cover board, the open top end of cover plate for sealing outer housing, is set among cover board
Be equipped with one and go out sound net, there is among outer housing an installation cavity, horn assembly is installed in installation cavity, the horn assembly it is outer
Portion is installed by one U-tube；
The centre of U-tube has a U-shaped channel, and the both ends in the U-shaped channel are open, and face is U-shaped on the cover board
The both-side opening end in channel opens up an air hole, and the both-side opening end of the U-tube is bonded a spring section, spring section it is another
One end is bonded in the inner end of cover board by glue, and the air hole is opened in out the two sides of sound net.
The spring section uses a seamless spring as a preferred technical solution, and spring eye just spends air hole.
The bottom thread of the horn assembly connects two support columns, the bottom of two support columns as a preferred technical solution,
It is inserted in the positioning column of installation cavity bottom surface setting.
As a preferred technical solution, the two sides of the horn assembly respectively with two side contacts of U-tube, the U-tube
For Al-alloy metal pipe.
The beneficial effects of the utility model are: the utility model structure is simple, one section of spring section is set on earphone case,
So that when in use, spring section can be opened using the vibration of earphone, so that air hole conducting is ventilative, sealing is saturating when not in use
Stomata increases waterproof effect.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the schematic diagram of internal structure of the U-tube of the utility model.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only
It is an example in a series of equivalent or similar characteristics.
As depicted in figs. 1 and 2, including headset main body, the headset main body include outer housing 1 and cover board 8, and cover board 8 seals
The open top end of outer housing 1 is provided with one among cover board 8 and goes out sound net 6, has an installation cavity 11, installation among outer housing 1
Horn assembly 5 is installed, the external of horn assembly 5 installs a U-tube 3 in chamber 11；The centre of U-tube 3 has a U-shaped channel
14；
The both ends in U-shaped channel 14 are open, and the both-side opening end in the U-shaped channel 14 of face opens up an air hole on cover board 8
7, the both-side opening end of U-tube 3 is bonded a spring section 4, and the other end of spring section 4 is bonded in the inside of cover board 8 by glue
End, air hole 7 are opened in out the two sides of sound net 6.
Spring section 4 uses a seamless spring, and spring eye is just spending air hole 7, the bottom thread connection of horn assembly 5
Two support columns 13, the bottom of two support columns 13 are inserted in the positioning column 12 of 11 bottom surface of installation cavity setting, the two sides of horn assembly 5
Respectively with two side contacts of U-tube 3, U-tube 3 is Al-alloy metal pipe.
In the present embodiment, the structure that spring uses is that do not have apertured spring, fits closely between spring ring, only works as bullet
Just will appear gap when spring is shaken or reverses, among spring, this spring be when not in use do not have it is apertured, also
Be the utility model under static state when, spring is seamless, entire air hole would not also be connected, when in use, loudspeaker group
The vibration meeting of part is so that spring vibration or Light deformation, Light deformation can be connected with external air flow, can lead so in the process
Penetrating stomata.
The beneficial effects of the utility model are: the utility model structure is simple, one section of spring section is set on earphone case,
So that when in use, spring section can be opened using the vibration of earphone, so that air hole conducting is ventilative, sealing is saturating when not in use
Stomata increases waterproof effect.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
