Abstract
The utility model discloses a single track bluetooth headset IFA and combination antenna of extending, including the earphone body, the earphone body includes preceding shell, backshell, and preceding shell and rear shell connected form the cavity, the backshell in be equipped with PCB circuit board and power supply structure, be equipped with audio frequency processing apparatus, bluetooth transmittal equipment on the PCB circuit board, audio frequency processing apparatus include audio processor and audio decoder ware, audio processor connects crystal oscillator, flash memory, antenna and LED pilot lamp, fader, microphone are connected to the audio decoder ware, power supply structural connection audio processor and audio decoder ware, the antenna adopt the IFA antenna of IFA form for PCB printing antenna and punching press antenna, PCB printing antenna, at the epitaxial punching press antenna of terminal joining of PCB printing antenna. The IFA antenna combines together with the punching press antenna, and it is little to adapt to the headroom, and the complicated earphone of environment can obtain good performance again.
Description
Technical field
This utility model is related to bluetooth earphone production field, is exactly a kind of single sound channel bluetooth headset IFA and extension
With reference to antenna.
Background technology
Modern society's science and technology is maked rapid progress, and the reception antenna development for being applied to mobile electronic product also relatively lags behind, main flow
The reception antenna of mobile electronic product all realize that built-in antenna also occurs in recent years using external collapsible mast.Outward
Although putting collapsible mast can meet index request in performance, in service life, mechanical strength, property easy to use, especially
Outward appearance aspect is difficult to meet customer requirement.Although and built-in antenna is in service life, mechanical strength, property easy to use and outward appearance
On meet the requirement of its client, but less than external collapsible mast in performance, while higher in price.With wearable
The development of technology, miniaturization, high performance smart machine are becoming increasingly popular, therefore, for wireless Bluetooth headsets, its day
Line is faced with some challenges, and number bluetooth earphone big absolutely has problems with, and first is that antenna headroom area is little, and surrounding is paid no attention to
Think, second is that narrow bandwidth, efficiency are low.
Utility model content
The technical problems to be solved in the utility model is that now number bluetooth earphone big absolutely has problems with, and first is antenna
Headroom area is little, and surrounding is undesirable, and second is that narrow bandwidth, efficiency are low.
To solve above-mentioned technical problem, this utility model adopts following technological means：
A kind of single sound channel bluetooth headset IFA is combined antenna, including headset body with extension, headset body include fore shell, after
Shell, fore shell and back cover connect to form cavity；PCB and power delivering structure are provided with described back cover, in PCB
Apparatus for processing audio, Bluetooth transmission equipment are provided with, described apparatus for processing audio includes audio process and audio decoder, sound
Frequency processor connection crystal oscillator, flash memory, antenna and LED light, audio decoder connection volume controller, mike, power supply is supplied
Connect audio process and audio decoder to structure, described antenna is PCB printed antennas and punching press antenna, and PCB prints day
Line adds the punching press antenna of extension using the IFA antennas of IFA forms in the end of PCB printed antennas.
Preferably, this utility model further technical scheme is：
Size is provided with described back cover for 4mm × 2.5mm days space of lines.
Described power delivering structure includes battery and connection battery, the supply lines of PCB.
Foam is added between described antenna and battery so as to which distance reaches more than 3mm.
Described antenna is provided with titanium alloy layer in solder joint.
The fast development of wireless communication technology, has effectively promoted light, small-sized, low profile antenna research and development.Tied based on IFA
The miniature antenna of structure, embodies small volume, with wide, easily makes built-in, simple structure, and low cost and other advantages are strong so as to have
Big vitality and market share power.It is exactly to increased at the edge of paster that IFA antennas are different from where general microstrip antenna
Short-circuit face, to increase the bandwidth of antenna.Meanwhile, this antenna is usually quarter-wave, micro- with traditional half-wavelength paster
Band antenna is compared, and its size reduces 50%, greatly reduces antenna size.IFA antennas another features is that its one kind can be
The good antenna form of metal surface work.
According to IFA structural antenna features, a label antenna for being operated in 915MHz is devised.And by adopting：Radiation
Face is slotted and bending structure, and selection antenna height, preferable equilibrium point between bandwidth and gain, the beamwidth of antenna is more than 3.6%, height
Spend for 3mm, gain is more than 2.4dBi, substantially meets index, and with good omni-directional, the antenna is actually two-band day
Line, simply by bending structure, two resonance points of adjustment are close, to increase bandwidth.
This utility model adopts PCB printed antennas+punching press antenna combination, and PCB adopts printed antenna, big in order to reduce periphery
The interference of device, using IFA forms, due to the restriction of motherboard space, the headroom for leaving antenna for is 4mm × 2.5mm, for this purpose,
Print IFA antennas end add extension punching press antenna, foam is added between antenna and battery so as to distance reach 3mm with
On, understanding that antenna efficiency maximal efficiency reaches 39% according to Fig. 3, measured result is more satisfactory, and measured distance reaches 10 meters, IFA days
Line adapted to that headroom is little in combination with punching press antenna, both, the complicated earphone of environment, and can obtain good performance.
