Abstract
The invention discloses an antenna. The antenna is characterized in that a grounding metal part of an earphone socket is connected to a signal feed-in circuit by a matching circuit, and the matching circuit can be adjusted, so that resonance effects can be realized by the grounding metal part, and the grounding metal part can be used as the antenna for receiving and transmitting signals. The invention further provides a wireless communication device with the antenna. The antenna and the wireless communication device have the advantages that the grounding metal part of the earphone socket is used as the antenna, and accordingly spaces occupied by the wireless communication device can be effectively diminished.
Description
Technical field
The present invention relates to a kind of antenna, particularly relate to a kind of antenna utilizing earphone base.
Background technology
Along with the fast development of radio communication device, the demand of client to mobile phone is also more and more higher, mobile phone just towards large-size screen monitors, ultra-thin and metallization future development, which results in the space that may be used for Antenna Design also more and more less, how to become a major challenge at limited spatial design antenna.
Grounding pin on the accessory earphone socket of mobile phone is connected with grounded metal part, OMTP earphone is OMTP (Open Mobile Terminal Platform, OMTP) the earphone standard formulated, coordinates the overall length of the grounded metal part of the earphone socket of OMTP earphone to be approximately 14mm.The frequency range of bluetooth is about 2.4GHz, and for desirable Bluetooth antenna, its length should be 15 ~ 30mm.And existing mobile phone is generally all provided with Bluetooth antenna to realize Bluetooth function, take mobile phone space.
Summary of the invention
For the problems referred to above, be necessary to provide a kind of antenna utilizing earphone socket.
Separately, the radio communication device that a kind of this antenna of application is provided is necessary.
A kind of antenna, it is the grounded metal part of the earphone socket of radio communication device.
A kind of radio communication device, it comprises earphone socket, match circuit and signal feed-in circuit, this earphone socket comprises grounded metal part, this grounded metal part is connected to this signal feed-in circuit by match circuit, adjust this match circuit, to make this grounded metal part produce resonance, thus using the antenna of this grounded metal part as receiving and transmitting signal
The grounded metal part of earphone socket as antenna, can be effectively reduced the space of radio communication device by the present invention.

Fig. 2 is the structural representation of another angle of earphone socket shown in Fig. 1.
Fig. 3 is the circuit diagram of radio communication device of the present invention.
Main element symbol description
Following embodiment will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1 to Fig. 3, the radio communication device 1 of better embodiment of the present invention comprises earphone socket 100, match circuit 200, signal feed-in circuit 300 and voicefrequency circuit 400.
Described earphone socket 100 comprises pedestal 10, earphone jack 20, grounding pin 30, microphone pin 40, left channel pin 50, R channel pin 60 and grounded metal part 70.Earphone socket 100 can also comprise pin for subsequent use, and these pins can as left channel pin 50 for subsequent use, R channel pin 60, can also as the detection pin for detecting.
This grounded metal part 70 is attached at the surface of pedestal 10, and this grounded metal part 70 comprises the first connecting portion 71, second connecting portion 72 and the 3rd connecting portion 73 that connect successively.Described first connecting portion 71 and the 3rd connecting portion 73 are arranged on the side surface of opposing parallel pedestal 10.This first connecting portion 71 and the 3rd connecting portion 73 all roughly rectangular, this first connecting portion 71 offers rectangular first fluting the 710, three connecting portion 73 and offers the second rectangular fluting 730.This first connecting portion 71 is electrically connected at this grounding pin 30.This second connecting portion 72 is rectangular or substantially rectangular, offers a breach 720 in the middle part of it near earphone jack 20, and breach 720 place of this second connecting portion 72 extends one in wavy shell fragment 740 towards earphone jack 20 direction.
This grounding pin 30 is connected to signal feed-in circuit 300 by match circuit 200, for carrying out feed to ground connection metalwork 70.When this signal feed-in circuit 300 FD feed, by adjustment match circuit 200, grounded metal part 70 is made to produce resonance, thus using grounded metal part 70 as antenna.In the present embodiment, adjustment match circuit 200, with the signal making this grounded metal part 70 receive and dispatch about 2.4GHz frequency range, thus this grounded metal part 70 can be used as Bluetooth antenna and Wireless Fidelity (Wireless Fidelity, WIFI) antenna.Preferably, the inductance L of this grounded metal part 70 also ground connection in parallel, this inductance L, for ensureing the audio signal ground connection of low frequency, can prevent the loss of the aerial signal of high frequency simultaneously.
The microphone pin 40 of this earphone socket 100, left channel pin 50 and R channel pin 60 are all electrically connected at voicefrequency circuit 400.
The grounded metal part 70 of earphone socket 100 is used as antenna by the present invention, effectively can save the space of radio communication device 1.
In addition, those skilled in the art also can make various amendments in other forms and details, interpolation and replacement in the claims in the present invention scope of disclosure and spirit.Certainly, the changes such as these various amendments made according to the present invention's spirit, interpolation and replacement, all should be included within the present invention's scope required for protection.
