Abstract
The utility model discloses a kind of bluetooth headsets of self-expanding filling external auditory canal, earplug on the bluetooth headset is the earplug expanded by thermoinduction, it is internal filled with thermal expansion cotton, after built-in earplug fills in ear, thermal expansion cotton senses the temperature in earhole, it can gradually expand and stopper ear plug piece to form sealing, since the earplug after expansion pushes against earhole inner wall, not fall out.
Description
Technical field
The utility model relates to ear phone technology fields, particularly relate to a kind of bluetooth ear of self-expanding filling external auditory canal
Machine.
Background technique
In the prior art, the earphone for filling in ear generally can prevent the pronunciation unit of earphone equipped with elastic ear plug flexible
Hurt nest.
Elastic ear plug in the prior art is usually soft silica gel material, just can be with after needing to stopper after being placed in earphone
External auditory canal is stoppered.
Utility model content
Aiming at the shortcomings in the prior art, the technical problem to be solved by the present invention is to provide a kind of self-expandings to fill out
Fill the bluetooth headset of external auditory canal.
In order to solve the above technical problems, the utility model is realized by following scheme: a kind of self-expanding filling external auditory canal
Bluetooth headset, which includes ear casing and the phonation unit being arranged in the ear casing, is socketed in the ear
Earplug on the recessed circle of casing outlet sound mouth outer wall, the earplug are the earplug expanded by thermoinduction.
Further, the earplug appearance is sealant, and thermal expansion cotton is filled with inside sealant.
Further, the sealant is flexible seal layer, follow the thermal expansion cotton expand and expansion or its follow
The thermal expansion cotton restores and shrinks.
Further, it is 36 degree, less than the thermal expansion cotton of 36 degree contractions that the thermal expansion cotton, which is a kind of expansion start temperature,.
Compared with the existing technology, the beneficial effects of the utility model are: the utility model earplug is swollen by thermoinduction
Swollen earplug, internal filled with thermal expansion cotton, after built-in earplug fills in ear, thermal expansion cotton senses the temperature in earhole
Degree, can gradually expand and stopper ear plug piece to form sealing, since the earplug after expansion pushes against earhole inner wall, not fall out.
Detailed description of the invention
Fig. 1 is the utility model blue-tooth earphone structure schematic diagram.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
The advantages of clearly and completely describing, enabling the utility model and feature are easier to be readily appreciated by one skilled in the art, thus to this
The protection scope of utility model is more clearly defined.Obviously, the utility model described embodiment is only
The utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
Technical staff's every other embodiment obtained without making creative work belongs to the utility model protection
Range.
It is in the description of the present invention, it should be noted that term " center ", "upper", "lower", "left", "right", " perpendicular
Directly ", the orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only
For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific
Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.In addition, term " the
One ", " second ", " third " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified
Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally
Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary,
It can also be the connection inside two elements, can be wireless connection, be also possible to wired connection.For the common skill of this field
For art personnel, the concrete meaning of above-mentioned term in the present invention can be understood with concrete condition.
In addition, as long as technical characteristic involved in the utility model different embodiments disclosed below is each other
Not constituting conflict can be combined with each other.
The specific structure of embodiment 1, the utility model is as follows:
Attached drawing 1, a kind of bluetooth headset of self-expanding filling external auditory canal of the utility model are please referred to, which includes
Ear casing and the phonation unit 1 being arranged in the ear casing, the ear being socketed on the recessed circle of ear casing outlet sound mouth outer wall
Plug 2, the earplug 2 is the earplug expanded by thermoinduction.
A kind of optimal technical scheme of the present embodiment: 2 appearance of earplug is sealant, and it is swollen to be filled with heat inside sealant
Swollen cotton.
A kind of optimal technical scheme of the present embodiment: the sealant is flexible seal layer, follows the thermal expansion cotton
Expansion and expand or it follows thermal expansion cotton recovery and shrinks.
A kind of optimal technical scheme of the present embodiment: the thermal expansion cotton is that a kind of expansion start temperature is 36 degree, is less than
The thermal expansion cotton of 36 degree of contractions.
Embodiment 2:
The earphone plug of the utility model is entered into ear, since the earplug of the utility model is thermal expansion cotton, is being manufactured
When, the temperature of design is 36 degree or more and expands, and since the temperature in ear is closest to 37 degree of human body temperature, work as ear
After filling in ear, expanded by heating, and ear is stoppered, sealing structure is formed, is not fallen out.
When removing earphone, due to earplug ingress of air, the temperature in general air is less than 36 degree (in addition to temperature is higher
Season), earplug can gradually taper up, and elastic sealing layer follows the contraction of thermal expansion cotton and tightens.
In addition, the bluetooth headset of the utility model is built-in with bluetooth module, bluetooth module is common bluetooth mould on the market
Block, earphone can establish connection by bluetooth and intelligent mobile terminal.
Above description is merely a prefered embodiment of the utility model, is not intended to limit the patent model of the utility model
Enclose, equivalent structure or equivalent flow shift made by using the description of the utility model and the drawings, or directly or
It connects and is used in other relevant technical fields, be also included in the patent protection scope of the utility model.
