Description
Technical field
This utility model relates to antenna, particularly relates to a kind of antenna structure for bluetooth earphone and bluetooth earphone.
Background technology
In recent years, along with the fast development in wireless wearable device market, bluetooth earphone is constantly towards compact target
Evolution, the spendable space of its Bluetooth antenna reduces the most increasingly, and engineers and technicians are faced with and the most effectively expand bluetooth ear
Machine antenna performance, reduction data transmission loss efficiency, and in limited space, utilize the high performance indigo plant of existing Environment Design
Tooth antenna.But in existing bluetooth earphone, the antenna of Bluetooth headset little, that data transmission loss is low that takes up room not yet occurs.
Utility model content
The technical problems to be solved in the utility model is, for the deficiencies in the prior art, it is provided that a kind of energy Appropriate application
Bluetooth earphone inner space, the loss of data can be reduced, and for the antenna structure of bluetooth earphone.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that.
A kind of antenna structure for bluetooth earphone, it includes the pcb board being located in shell and is located at outer casing end
USB joint, described pcb board is printed with lying copper region and non-lying copper region, and described USB joint is fixing with the non-lying copper region of pcb board to be connected
Connecing, described non-lying copper region is printed with current feed department, described lying copper region is electrically connected with by current feed department with USB joint, by institute
State lying copper region, current feed department and USB joint and constitute antenna body.
Preferably, described pcb board extends along the length direction of shell.
Preferably, the size of described pcb board is 43.78mm*9.63mm*0.8mm.
Preferably, described USB joint is located at shell one end away from earphone horn.
Preferably, described USB joint is micro USB socket.
A kind of bluetooth earphone, includes shell, is provided with above-mentioned antenna structure in described shell.
In antenna structure disclosed in this utility model, lying copper region, current feed department and the pcb board end that pcb board is printed
USB joint constitutes the main part of antenna, can be adjusted the resonant frequency of antenna by the length changing lying copper region, by adjusting
The position of current feed department can also adjust the resonant frequency of antenna, and then meets the band requirement to antenna.Meanwhile, USB is connect
Head as radiant section, owing to USB joint is naked state in the end of shell, thus avoids and is blocked by shell, fall
Low loss, is favorably improved efficiency of transmission, additionally, this utility model is without separately putting radiation component, preferably saves
The inner space of bluetooth earphone so that bluetooth earphone can preferably develop towards miniaturization, and then meets the market demand.
Accompanying drawing explanation
Fig. 1 is the cut-away view of bluetooth earphone.
Fig. 2 is the structure chart of pcb board and USB joint.
Fig. 3 is the return loss characteristic curve of antenna structure.
Detailed description of the invention
With embodiment, this utility model is described in more detail below in conjunction with the accompanying drawings.
The utility model discloses a kind of antenna structure for bluetooth earphone, shown in Fig. 1 and Fig. 2, it includes
The pcb board 1 being located in shell 4 and the USB joint 2 being located at shell 4 end, described pcb board 1 is printed with lying copper region 7 and does not covers
Copper district 6, described USB joint 2 is fixing with the non-lying copper region 6 of pcb board 1 to be connected, and described non-lying copper region 6 is printed with current feed department 3, institute
State lying copper region 7 to be electrically connected with by current feed department 3 with USB joint 2, by described lying copper region 7, current feed department 3 and USB joint 2
Constitute antenna body.
In above-mentioned antenna structure, lying copper region 7, current feed department 3 and the USB joint 2 of pcb board 1 end that pcb board 1 is printed
Constitute the main part of antenna, the resonant frequency of antenna can be adjusted by the length changing lying copper region 7, by adjusting current feed department
The position of 3 can also adjust the resonant frequency of antenna, and then meets the band requirement to antenna.Meanwhile, USB joint 2 is made
For radiant section, owing to USB joint 2 is naked state in the end of shell 4, thus avoid blocking by shell 4, reduce
Loss, is favorably improved efficiency of transmission, additionally, this utility model is without separately putting radiation component, preferably saves indigo plant
The inner space of tooth earphone so that bluetooth earphone can preferably develop towards miniaturization, and then meets the market demand.
As a kind of optimal way, described pcb board 1 extends along the length direction of shell 4.The size of described pcb board 1 is
43.78mm*9.63mm*0.8mm。
In the present embodiment, described USB joint 2 is located at shell 4 one end away from earphone horn 5.Further, described USB
Joint 2 is micro USB socket.In actual application, current feed department 3 can be connected on the metal-back of USB joint 2 so that USB connects
The metal-back of 2 uses as radiation component.
Based on above-mentioned antenna structure, this utility model is also disclosed a kind of bluetooth earphone, and this bluetooth earphone includes shell 4,
It is provided with above-mentioned antenna structure in described shell 4.After tested, refer to Fig. 3, the antenna structure of this bluetooth earphone is at 2.4-
The design requirement less than-15dB all can be met in 2.5GHz.
In the bluetooth earphone that the utility model proposes and antenna structure, USB interface can not only be used for charging inlet and connects with outside
Connect, as an antenna part, and preferable antenna performance can be capable of at 2.4-2.5GHz again, meet wanting of Antenna Design
Ask.This utility model novel structure, form is simple, it is easy to accomplish, can effectively utilize space, enable bluetooth earphone to accomplish frivolous
Short and small, significantly reduce manufacturing cost.
The above is this utility model preferred embodiment, is not limited to this utility model, all in this practicality
Amendment, equivalent or the improvement etc. made in novel technical scope, should be included in the model that this utility model is protected
In enclosing.
