In the described CMMB earphone antenna of the utility model, be in series with the RF impedance element on the earth signal line in said earphone cord.
In the described CMMB earphone antenna of the utility model, said RF impedance element is inductance or magnetic bead.
In the described CMMB earphone antenna of the utility model, said CMMB antenna is a copper cash.
In the described CMMB earphone antenna of the utility model, said antenna protection cover is the detachable protective cover.
In the described CMMB earphone antenna of the utility model, it is the protective sleeve with said earphone one that said antenna protection overlaps.
In the described CMMB earphone antenna of the utility model, said antenna protection cover is garment bag.
The utility model solves another technical scheme that its technical problem adopted:
A kind of intelligent terminal is provided; Comprise earphone socket and CMMB earphone antenna mentioned above; Said earphone socket be used to the to peg graft headset plug of said CMMB earphone antenna, the antenna feed point of said CMMB earphone antenna is connected with the feedback point of said intelligent terminal through said earphone socket.
Use and the utlity model has following beneficial effect: the CMMB antenna of the utility model is carrier with earphone cord, with the earphone shared interface, on the layout of pcb board, need not additional space; The CMMB antenna is a carrier with the earphone cord, is equivalent to external antenna, and the CMMB antenna directly is connected with the earth signal pin of headset plug, forms independent antenna feed point, can get a larger optimization on the performance;
Further, in the outside of earphone, the position of corresponding built-in said CMMB antenna also is provided with the antenna protection cover, the local hardness of strengthening the CMMB antenna area prevents that earphone cord is too soft, arbitrarily swings and influences antenna performance.
In addition, adopt independently copper cash realization CMMB antenna performance, reduced the realization cost.
Description of drawings
To combine accompanying drawing and embodiment that the utility model is described further below, in the accompanying drawing:
Fig. 1 is the structural representation of the utility model Embodiment C MMB earphone antenna.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, the utility model Embodiment C MMB earphone antenna is with the carrier of common earphone cord as the CMMB antenna, and adopts independently antenna, is equivalent to external antenna, and forms independently antenna feed point, can get a larger optimization on the performance; Also be provided with the antenna protection cover at the outside of earphone, the position of corresponding built-in CMMB antenna, the hardness of CMMB antenna area has been strengthened in the part, and the CMMB antenna can arbitrarily not swung with earphone cord influences antenna performance.The CMMB earphone antenna of the utility model embodiment can be used in the various intelligent terminals, like smart mobile phone, MP4, PDA etc.
As shown in Figure 1; The CMMB earphone antenna of the utility model embodiment; Comprise earphone, earphone comprises headset plug 1 and the earphone cord 2 that is connected with this headset plug, and the earth signal line 6 in the earphone cord is connected with the earth signal pin 5 of headset plug; Certainly earphone other structures of also comprising common headphones and being had are not given unnecessary details at this one by one.This CMMB earphone antenna also comprises independently CMMB antenna 3, and CMMB antenna 3 is arranged on the root interior (promptly near the part that connects headset plug 1) of earphone cord 2, is connected with the earth signal pin 5 of headset plug, and CMMB antenna 3 is along the direction setting of earphone cord 2.CMMB antenna 3 adopts the separate signal lines, and not with the shared ground wire of FM as holding wire, form independently antenna feed point (being the tie point of CMMB antenna and headset plug earth signal pin), be convenient to optimize the CMMB antenna performance to a certain extent.
Outside earphone cord 2, the part of corresponding CMMB antenna 3 also is provided with antenna protection cover 4, this antenna protection cover 4 can the local hardness of strengthening the CMMB antenna area, prevents that earphone cord is too soft, arbitrarily swings and influence antenna performance.The length of antenna protection cover 4 can be according to the length setting of CMMB antenna 3.
