Description

The case type antenna configuration of wireless interspeaker

Technical field

The utility model relates to the case type antenna configuration of a kind of wireless telecommunications electronic product, particularly a kind of wireless interspeaker.

Background technology

Have the electronic product of radio wave communication function, need to transmit radio signal by antenna, the antenna of early stage electronic product is generally exposed design, and such as early stage mobile phone and wireless interspeaker are all provided with one section of antenna exposed; Along with electronic product more and more great attention to whole moulding and designer trends attractive in appearance, the concealed antenna among housing antenna being arranged at electronic equipment has become current design main flow.On the other hand, in order to the aesthetic feeling of the texture and entirety that promote electronic product outward appearance, the metal shell using metal material to make also becomes the designer trends of electronic product of new generation.

For intelligent mobile phone or wireless interspeaker, the advantage of the metal shell of metal material manufacture comprises: have preferably that sense of touch, hardness height are not easy to wear, structural strength is good, anti-pressure ability good, and heat conductivity is good, therefore can well protects inner part and easily dispel the heat; Because metal or wire netting have the characteristic stopping that radio wave transmits, the problem therefore adopting metal material manufacture phone housing first will overcome is exactly must overcome metal-back to know from experience the problem stopping that radio wave transmits.

Become known for solving metal-back and know from experience a kind of technology stopping the problem that radio wave transmits, be use to stop that the material (such as plastic and glass) that radio wave transmits manufactures window at metal shell, the radio signal of concealed antenna can be passed through.Therefore, many, the heavier-weight of the number of spare parts of this handset shell and also volume larger.On the other hand, compare with the handset shell of all-metal material manufacture, the outward appearance that the more difficult in appearance acquisition of the handset shell using multiple unlike material to manufacture is consistent, after homochromy application processing procedure, still can there is a little aberration in the housing of such as different metal materials and plastic material.

Another kind becomes known for solving metal-back and knows from experience a kind of technology stopping the problem that radio wave transmits, such as published US Patent No. 20140247188A1 " Antennadeviceandelectronicapparatusincludingantennadevic e ", by cutting out slit at metal shell and arrange the mode of coil around slit, making metal shell can serve as antenna for transmitting radio signal.In addition, a kind of similar technology is disclosed at published US Patent No. 20140203981A1 " Antennadeviceandcommunicationterminaldevice ", where it is proposed a kind of antenna assembly that can make radio wave transmission metal shell without the need to slit, comprise a metal shell and power supply coil (feedcoil), wherein the side of metal shell has a notch part, magnetic Field Coupling is carried out with metal shell in the inside that power supply coil is located at metal shell, and coil of powering is configured in the position close to notch part.

" antenna structure of metal shell is integrated in " in addition at published Chinese patent CN103633434A, and published Chinese patent CN104584324A " the integration mechanism of electronic installation metal shell and antenna ", all disclose and cut out slit at metal shell, and by technology that antenna structure and metal shell combine.

The wireless telecommunications electronic product of above-mentioned several known employing concealed antenna, all inevitably form slit or breach at metal shell, but in order to keep aesthetic feeling and the integrality of the outward appearance of metal shell, described slit or breach all need can not stop that the material (such as plastics) that radio wave transmits is closed with plastics or other again, because plastics are different from the physical characteristic of metal, in another problem how both joining places keep the smooth Ze Shi manufacturer on surface to solve.
