Abstract
The embodiment of the utility model discloses a frequency-modulated antenna, which comprises a conductive contact and an antenna feed point of a frequency-modulated chip, wherein, the conductive contact is exposed on terminal casing and is connected with the antenna feed point of the frequency-modulated chip through a section of conductive cable; and the conductive contact is used for receiving frequency-modulated signals. By adopting the frequency-modulated antenna provided by the embodiment of the utility model, the mobile terminal can better receive the frequency-modulated signals under the condition without externally connecting or internally arranging the antenna.
Description
Technical field
The utility model relates to wireless communication technology field, relates in particular to a kind of frequency-modulated antenna.
Background technology
Integrated FM in portable terminal (Frequency Modulation, frequency modulation) radio function is very general.But, all must insert earphone during the realization frequency modulation function of most of portable terminal as frequency-modulated antenna or at the inner integrated frequency-modulated antenna of portable terminal.
The inventor is in realizing process of the present invention, and there are the following problems at least to find prior art:
The user must wear earphone can listen to FM receiver, makes troubles to the user like this; If use built-in frequency-modulated antenna, because the portable terminal inner space is limited, cause built-in antenna length too short, effect is poor.
The utility model content
The utility model embodiment provides a kind of frequency-modulated antenna, can make portable terminal received signal under the situation that does not have earphone or built-in aerial.
The utility model embodiment provides a kind of frequency-modulated antenna, is applied to portable terminal, comprising:
Conductive contact and frequency modulation antenna component feedback point;
Described conductive contact is emerging on the terminal enclosure, and links to each other with described frequency modulation antenna component feedback point by one section conductor cable;
Described conductive contact is used to receive FM signal.
Compared with prior art, the utlity model has following advantage:
Adopt method of the present utility model, not only have reception preferably, and realize that cost is low, under the situation that does not have external antenna or built-in aerial, user-friendly.

Fig. 1 is the utility model embodiment frequency-modulated antenna structural representation;
Fig. 2 is to be the frequency-modulated antenna structural representation of example with the mobile phone among the utility model embodiment;
Fig. 3 is the schematic diagram that imports metallic cable among the utility model embodiment in conductive contact into;
Fig. 4 is to be the frequency-modulated antenna structural representation of example with the MP3 player among the utility model embodiment.
Embodiment
The utility model embodiment provides a kind of frequency-modulated antenna, as shown in Figure 1, comprises conductive contact 100 and frequency modulation antenna component feedback point 200; Described conductive contact 100 is emerging on the terminal enclosure, and links to each other with described frequency modulation antenna component feedback point 200 by one section conductor cable 300; Utilize this section conductor cable 300 as antenna, this conductive contact 100 is used to receive FM signal.Can receive the FM signal by above-mentioned conductive contact 100, and when this conductive contact 100 touched other electric conductors (as metallic plate, human body), the quality of received signal can increase, and has reception preferably.
Be example below with the mobile phone, the frequency-modulated antenna that the utility model is provided is elaborated, as shown in Figure 2, on the back cover of mobile phone, reserve a conductive contact 100, the antenna feed point 200 that this conductive contact 100 is crossed the frequency modulation chip of one section conductor cable 300 and mobile phone inside links to each other, can receive FM signal by this conductive contact 100, under the situation that does not possess earphone or built-in aerial, the user also can use FM receiver function like this.
As shown in Figure 3, can pass the rope 400 that an inside comprises metal in the centre of above-mentioned conductive contact 100, as the antenna of received signal, this rope can also use as the lifting rope of mobile phone simultaneously.This conductive contact 100 is more conducive to adsorb external metallic conductor owing to have the metal of magnetic, so can select for use the metal that has magnetic to make.
For obtaining better audibility, this conductive contact 100 can be connected on any metal, for example elongated metal wire, large-area metallic plate, key of carrying etc., if it is closely interior when using without any metallics, also can keep contacting with finger with hard contact, utilize human body as frequency-modulated antenna,, generally also can obtain effect preferably in the stronger place of signal.
Below with MP3 (MPEG Audio Layer3, audio frequency according to dynamic image expert group standard compression) player is an example, the frequency-modulated antenna that the utility model is provided is elaborated, as shown in Figure 4, place, side at MP3 appears a conductive contact 100, this contact links to each other with the antenna component feedback point 200 of casing inside by one section conductor cable 300, can punch in the middle of this conductive contact 100, so that hang ornaments etc.Do not carrying under the situation of earphone, can utilize this conductive contact 100 to receive FM signal, in order to improve the quality of listening to, objects such as this conductive contact and conducting metal can contacted.
Adopt method of the present utility model, not only have reception preferably, and realize that cost is low, under the situation that does not have external antenna or built-in aerial, user-friendly.
More than disclosed only be several specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection range of the present utility model.
