Background technique
As the popularization degree of wireless technology is higher and higher, our demands to antenna are also more and more, higher and higher, spy
It is not that wearable small-sized, satellite system proposes more higher requirements to Antenna Design.Common Antenna Design is with interior
FPC antenna, SMT ceramics high-dielectric coefficient antenna or the stamping parts set are affixed directly on PCBA, and basic over-assemble is less square
Just, practical function is also bad.
Above-mentioned antenna is maximum the disadvantage is that current direction is very big on the influence of the application function of left and right ear, and extended mode is necessary
Have particular provisions, otherwise, antenna is resonance, but sense of current not to be also cannot improve well antenna application imitate
Fruit.
Thus, it is necessary to design the new bluetooth headset of one kind to solve the above technical problems.
Utility model content
The purpose of this utility model is to provide a kind of with the bluetooth headset for improving antenna performance.
To realize foregoing purpose, the utility model adopts the following technical solution: a kind of bluetooth headset comprising silica gel ear
Cap, shell, phonation unit, bracket, battery, circuit board and antenna element, the shell are equipped with accommodating space and convex towards inside
The tip stretched, the silica gel earcap cover on tip, and the phonation unit, bracket, battery and circuit board are contained in accommodating space,
Respectively with circuit board electrical connection, the phonation unit is located at tip for the phonation unit, battery and antenna element, the battery with
Circuit board is fixed on bracket, and the antenna element includes the image antenna and ground strip for being spaced from each other and coupling, the figure
Antenna arranges that the ground strip is located at accommodating space, and one end of ground strip is connect with circuit board, and the other end protrudes on the shell
Tip.
The ground strip is located on the outside of phonation unit as a further improvement of the utility model, and two sides tend to be parallel.
One end of the ground strip is welded on circuit board as a further improvement of the utility model,.
The image antenna is LDS antenna as a further improvement of the utility model, is arranged in the lateral surface of shell.
The image antenna is in electrical contact with the method for via hole and circuit board as a further improvement of the utility model,.
The circuit board is equipped with first, second be exposed in accommodating space as a further improvement of the utility model,
Metal clips and a tie point, the image antenna abut the feed-in for realizing signal and ground connection, institute with the first, second metal clips
Ground strip is stated to connect with tie point.
The shell includes the first shell mutually snapped together, second as a further improvement of the utility model,
Shell and the accommodating space being collectively formed in the first, second shell.
The direction of the electric current flowing of the image antenna of the utility model Bluetooth antenna is substantially parallel to face, close to
Outside ear hole, lossy dielectric is sponged very much, cannot be propagated relatively at a distance, and the electric current flowing of ground strip, substantially vertically
In face, Electromagnetic Wave Propagation can be sponged fewer parts by face, and when antenna working unit, image antenna and ground strip are generated
Resonance after the two combines, improves the radiation efficiency of antenna element entirety, also changes the current direction of antenna element, perpendicular to
Face, ensure that the flow direction of electric current, and efficient radiated electromagnetic wave realizes the seamless connection of left and right ear.Ground strip is in space
Extend inwardly in the case where size-constrained, advantageously reduce the volume of bluetooth headset, while realizing the perfect spoke of antenna element
Penetrate effect.
Detailed description of the invention
Fig. 1 is the stereoscopic schematic diagram of the utility model bluetooth headset.
Fig. 2 is the stereogram exploded view of the utility model bluetooth headset.
Fig. 3 is the stereogram exploded view of another angle of the utility model bluetooth headset.
Specific embodiment
Shown in please referring to Fig.1 to Fig.3, the utility model bluetooth headset 100 includes silica gel earcap 10, shell 20, sounding list
Member 30, bracket 40, battery 50, circuit board 60 and antenna element.
Shell 20 includes the first shell 21, second housing 22 and the accommodating space surrounded by the first, second shell 21,22
23, the first shell 21 is snapped together with second housing 22, and the first shell 21 has the tip 210 protruded out inwardly, to insert
Enter in ear hole, 10 sets of silica gel earcap on tip 210.
Phonation unit 30, bracket 40, battery 50, circuit board 60 and antenna element are respectively accommodated in 20 accommodating space 23 of shell
It is interior.
Battery 50 and circuit board 60 are fixed on bracket 40.
Phonation unit 30, battery 50 and antenna element are electrically connected with circuit board 60 respectively, and phonation unit 30 is located at tip
210, closer to the ear-drum of user.Battery 50 is to provide the power supply of bluetooth headset 100.
Circuit board 60 is equipped with the first, second metal clips 51,52 and a tie point 53 being exposed in accommodating space 23.
Antenna unit includes an image antenna 71 spaced apart from each other and a ground strip 72, which is LDS antenna,
