Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage more become apparent, and are described in detail specific embodiments of the invention below in conjunction with accompanying drawing.
The existing antenna form of hand-held mobile terminal comprises double loop antenna (singleloopanddualloopantenna), inverted folded antenna (IFA), planar inverted folded antenna (PIFA).These antenna type respectively has its condition used and performance in different hand-held mobile terminal environment, can select different antenna forms according to different requirements.
Existing antenna structure needs access with reference to ground, therefore existing antenna all has earth terminal.For PIFA antenna, as shown in Figure 1, the basic structure of PIFA antenna 200 comprises: the parasitic branch 203 of antenna cabling ground connection branch 201, antenna feed branch 202 and antenna.When designing antenna, the parasitic branch 203 of antenna cabling ground connection branch 201 and antenna need to do access with reference to process, astronomical cycle is on mobile phone, and the pcb board of mobile phone is as reference of antenna; As shown in Figure 2, generally that reference ground 301 on Mobile phone PCB 300 arranges shell fragment or other jockey access PIFA antenna 200, PIFA antenna 200 and pcb board 300 at right angle setting, due to pcb board also can arrange other device, for not affecting the radiance of antenna 200, antenna feed point should be tried one's best near the edge of pcb board 300, and such antenna is just away from other device, and radiance is less by other component influences; PIFA antenna and pcb board have certain distance, for dual-band antenna, are at least greater than 6mm, for three-frequency antenna, are at least greater than 7mm.
Also have an important device to be earphone socket in hand-held mobile terminal, as shown in Figure 3, earphone socket 100 comprises the earphone jack 103 for plugging headset plug; Figure 4 shows that three-section earphone plug, be from left to right followed successively by L channel ring, R channel ring and ground wire loop; Fig. 5 is four-section type headset plug, is from left to right followed successively by L channel ring, R channel ring, Mike's ring and ground wire loop; Fig. 6 is similarly four-section type headset plug, be followed successively by from left to right L channel ring, R channel ring, wire loop and Mike's ring; Although each Headphone structure distribution is different, all there is ground this structure of wire loop; In earphone jack 103, be provided with the pin position contact corresponding with each ring on described headset plug, substantially comprise: L channel, R channel, Mike and ground connection, the contact, pin position on headset plug in each ring and earphone jack 103 is Elastic Contact.
Earphone socket also has earth terminal.With reference to figure 3, the pedestal on earphone socket 100 is also provided with the ground metal layer 101 corresponding with headset plug ground wire loop, ground metal layer 101 can be made up of thin copper sheet; Ground metal layer 101 is connected with grounding pin 102, and grounding pin 102 is connected with pcb board 300 again, the reference ground 301 on access pcb board 300.After grounding pin 102 ground connection on earphone socket 100, produce electrical potential difference, generation current with reference to ground 301, drive earphone.
Can find, the PIFA antenna 200 on hand-held mobile terminal and the grounding pin 102 on earphone socket 100 all need the reference ground 301 accessed on pcb board 300; Along with the requirement of cell-phone function is more and more higher, the device on pcb board 300 can get more and more, then PCB motherboard space can be caused not enough, and the headroom district leaving antenna for is less.
For solving the problem, with reference to figure 7 and Fig. 8 and shown in composition graphs 3, the invention provides a kind of earphone socket, comprise earphone base 104, earphone base 104 material is insulator, and insulator is plastics or pottery, and earphone socket 100 is provided with the ground metal layer 101 corresponding with earphone jack 103, after earphone jack interpolation enters headset plug (shown in Fig. 4-Fig. 6), the grounding pin of headset plug is connected with ground metal layer 101.
Continue with reference to figure 7 and Fig. 8 and shown in composition graphs 1, the reference ground 301 on access pcb board 300 is all needed due to the PIFA antenna 200 on hand-held mobile terminal and the grounding pin 102 on earphone socket 100, for saving the space of pcb board 300, the ground metal layer 101 on earphone socket 100 is connected with antenna 200; Ground metal layer 101, as the reference ground of signal source, also can do grounding, and ground metal layer 101 is connected with the reference ground 301 on pcb board 300 by grounding pin 102; In the present invention, ingenious utilization earphone socket carrys out designing antenna, need antenna cabling ground connection branch 201 (shown in Fig. 7) or parasitic branch 203 (shown in Fig. 8) to be connected with the ground metal layer 101 on earphone base 100 according to design, ground metal layer 101 is connected with the reference ground 301 on pcb board 300 by the grounding pin 102 on pedestal 100 again, achieve PIFA antenna 200 and ground metal layer 101 and all access reference ground 301 on pcb board 300, save the space of pcb board 300.
Like this, ground metal layer 101 on earphone socket 100 becomes a part for antenna, when the space that mobile terminal is used for designing antenna is less, ingenious ground metal layer 101 designing antenna utilized on earphone socket, make the ground metal layer 101 of earphone socket participate in the work of antenna 200, ground metal layer 101 is as a part for antenna 200 radiant body; Antenna 200 utilizes ground metal layer 101 realize the transmitting of antenna 200 or receive radio wave function, and antenna and earphone socket realize multiplexing, save mobile terminal device space.
It should be noted that, in the embodiment of the present invention, the form of antenna is PIFA, but the form of antenna is not limited only to PIFA, also comprise: IFA (inverted folded antenna), Loop (single loop antenna) etc., need in any antenna system to access the antenna with reference to ground form, the ground connection branch of these antenna all can be connected with the ground metal layer 101 of earphone socket, can be applied in the present invention.
The present invention also provides a kind of hand-held mobile terminal, comprises described earphone socket.
Although the present invention discloses as above, the present invention is not defined in this.Any those skilled in the art, without departing from the spirit and scope of the present invention, all can make various changes or modifications, and therefore protection scope of the present invention should be as the criterion with claim limited range.
