Specific implementation mode
For a clearer understanding of the technical features, objectives and effects of the utility model, now control attached drawing is detailed
Illustrate specific embodiment of the present utility model.
As shown in Fig. 1, Fig. 2 and Fig. 3, in one embodiment of bluetooth headset of the utility model, bluetooth headset includes earphone
Shell and Bluetooth antenna 20；Earphone case is plastic part；Bluetooth antenna 20 includes the metal spoke being arranged in earphone case outer surface
Arm 21 is penetrated, and is arranged in earphone case inner surface and the metal feed point 22,23 connected is connected with radiation arm 21.
It is appreciated that the space of external shell and enclosure interior made of the usual plastic material of prior art bluetooth headset,
The shape of shell is designed according to the shape of ear sound channel entrance, and enclosure interior space is used for placing head circuit unit.For side
Just, antenna 20 can be designed in headset body, is then connected to the electricity inside earphone equipped with tie point in headset body
Road unit can save 20 placement space of antenna.Specifically, the metal radiation arm 21 of antenna to be arranged to the appearance in plastic casing
Face, to ensure the radiance of antenna 20, the setting of metal feed point 22,23 that antenna 20 is used to connect with head circuit unit exists
The inner surface of plastic casing, the connection of convenient antenna 20 and head circuit unit, it is also ensured that the beauty of earphone.It can manage
Solution, metal feed point 22,23 pass through enclosure interior, conducting connection with radiation arm 21.
Further, antenna 20 includes laser formation antenna.Such as common LDS antennas, pass through the design of laser formation
Mode and by laser carving-change depositing process, antenna 20 is designed on the surface of shell, antenna 20 may be implemented in the one of shell
Change, the cabling of convenient antenna 20, do not influence the radiation of antenna 20, saves space.Certain LDS antenna schemes are appearance surface antenna
The preferred embodiment of technique can also use other similar skin antenna design schemes in some embodiments.
Further, 21 surface of radiation arm is equipped with oil spout.It is appreciated that 20 radiation arm of antenna in surface of shell is arranged
21 be metal material, in order to protect 20 surface of antenna, usually shows to be coated with one layer of green oil in the metal of antenna 20, oil spout technique is adopted
The protection to 20 metal material of antenna can be realized with common prior art.Prevent the oxidation of metal, and extraneous interference.
Further, oil spout thickness is 115 μm -156 μm.Can be understood as oil spout thickness can voluntarily select as needed
It selects, in some embodiments, the thickness by debugging oil spout realizes the best design of antenna 20.
Further, in some embodiments, earphone case includes first shell 11 and second shell 12, second shell 12
Equipped with pleasant end 121, antenna 20 is arranged in first shell 11.It is appreciated that entire earphone passes through two mutually matched shells
Body assembles, and pleasant end 121 is located in second shell 12, and on pleasant end 121 or entire second shell 12 can be equipped with
Soft silica gel improves the use comfort of earphone, promotes user experience.And be first shell 11 in that outside part of earphone,
Then can be individually designed, by the design of antenna 20 in the first shell 11, it can be protected in the case where not influencing using comfort
Demonstrate,prove the radiation of antenna 20.
Further, antenna 20 is arranged in 11 lower part of first shell.It is appreciated that earphone is in use, more or less
It can be blocked by human body, such as when earphone plug enters ear in use, the outer surface of earphone can be with ear apart from close.Even
First shell 11 on the outside of the direction of earphone, can also be affected.In order to ensure the radiation effect of earphone antenna 20, from human body work
The original painting of Cheng Xue wearings judges that lower section is better than the radiance of antenna.I.e. by the lower part of the first shell 11 of antenna 20, this
Sample is blocked by ear to be influenced to reduce, reach antenna 20 use it is optimal.
Further, 11 outer surface of first shell is level-one appearance.It is appreciated that according to after the completion of assembling product whether
Exposed that the face of product is divided into level-one, two level and three-level appearance, wherein level-one appearance refers in product normal use easily
In the surface seen, it is desirable that there is best presentation quality.Two level appearance：The surface that can't see in normal use, but require to have
Excellent presentation quality.Three-level appearance：The inner surface that user can't see does not require excellent presentation quality.This practicality is new
The first shell 11 of the bluetooth headset of type be it is exposed outside, can be immediately seen in use.So it is typically designed to level-one appearance,
The design of level-one appearance simultaneously can ensure the more dominance energy of the antenna 20 of its surface design.
Further, feed point includes electric feed point 22 and ground feed point 23, is connect with radiation arm 21.Specifically, antenna 20 is set
Meter can design the electric feed point 22 of connection circuit signal input and as needed for circuit connecting, and for antenna 20
The ground feed point 23 debugged, it will be understood that can be designed as needed here, and the electric feed point 22 of design and ground feed point
23 position.The connection of itself and radiation arm 21 follows 20 design principle of antenna.Such as 20 design principle of PIFA antennas may be used
Antenna 20 is designed.
Further, electric feed point 22 connects radiation arm 21 by the blind hole that laser carving is plated respectively with ground feed point 23.It can manage
Solution uses blind hole design method in circuit, the connection of design connection electric feed point 22 and ground feed point 23 and radiation arm 21 here.
By cross this design, effectively return kept away in use (product the brings human ear into) number of people to the shadow of antenna 20
It rings.Product is designed in outmost surface, and the distance apart from the number of people has the distance of 8MM, efficiently reduces the number of people to antenna 20
(FS and BHR/L influences are small) is influenced, product is promoted in 20 efficiency of antenna of 2400-2500MHz, promotes the directionality of antenna 20.
Specifically, by by taking LDS Antenna Designs as an example, below to pass through 20 efficiency of passive antenna of LDS design schemes.
In 2400-2500MHz frequency ranges, the whole efficiency of antenna 20 is all 35% or more.Following table is that the antenna performance of each frequency point refers to
Mark test data, it can be seen that the efficiency average value of antenna is 38%, and efficiency is higher by one times or so than traditional design scheme.
In addition it is also possible to find out the promotion of the performance of antenna from the standing wave S parameter figure of Fig. 4 antennas 20.
