Abstract
The disclosed mobile phone with radio function comprises: a radio unit, and an piece of antenna connecting with receiving end of radio. This invention introduces much convenience to user enjoy.
Description
Technical field
The present invention relates to a kind of mobile phone, particularly a kind of mobile phone with function of radio receiver.
Background technology
Broadcast receiver operation principle on the mobile phone by antenna and frequency-selective network received signal, is carried out mixing and demodulation after the LNA amplification by chip internal as shown in Figure 1, and signal is reduced into audio signal output.Wherein the frequency of frequency mixer can be changed in the scope of 87.5-108MHz and 76-90MHz by software control.
Existing mobile phone with function of radio receiver need insert earphone and could use, because, independent antenna is not set on existing mobile phone, must utilize earphone cord as reception antenna, therefore in the FM playing device that in the broadcast receiver of mobile phone, is comprised, must comprise a judging unit, judge whether to insert earphone, if do not insert earphone, just can not broadcast listening.
Summary of the invention
Technical problem to be solved by this invention provides a kind of equipment, does not need to insert earphone, directly uses the loudspeaker of mobile phone just can broadcast listening.
The objective of the invention is to be achieved through the following technical solutions:
A kind of mobile phone with function of radio receiver comprises a broadcast receiver unit, also comprises an antenna, and its receiving terminal with this broadcast receiver unit links to each other.
Wherein, the S-shaped handset shell inside that is attached to of this antenna.This antenna is the unit antenna, and its length is 1/4 wavelength.Particularly, this antenna length is 75 centimetres.
In addition, this broadcast receiver unit comprises a broadcasting device, and it comprises: antenna judge module, output handover module, frequency adjustment module and audio playing module.
Positive progressive effect of the present invention is: removed from and must can listen to FM broadcasting under the situation of inserting earphone, made and use the mobile phone broadcast listening to become simpler.
Description of drawings
Wireless fundamental diagram on Fig. 1 mobile phone.
Fig. 2 is the structural representation of one embodiment of the invention.
Fig. 3 is a broadcasting device structured flowchart in the present embodiment.
Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
As shown in Figure 2, a kind of mobile phone with function of radio receiver wherein is provided with a broadcast receiver unit 10 and an antenna 20, and antenna 20 links to each other with the receiving terminal 11 of this broadcast receiver unit 10.
These antenna 10 S-shaped handset shell inside that are attached to.
Any antenna all resonance will receive the signal of which frequency on certain frequency, just need antenna resonance on that frequency.The key data that the resonance problems of antenna relates to is wavelength and 1/4th.
Formula of wavelength is 300/f, and f is a frequency, then just can calculate wavelength according to resonance frequency, and 1/4 wavelength is to be called Hertz antenna.
This antenna 20 is the unit antenna, and its length is 1/4 wavelength, and further, this antenna length is 75 centimetres.
In addition, this broadcast receiver unit 10 comprises a broadcasting device 30, comprising: antenna judge module, output handover module, frequency adjustment module and audio playing module.Above-mentioned each module is prior art.
Above-mentioned broadcasting device 30 is with the difference of prior art FM playing device: it does not comprise described judging unit.
