(c) radio-frequency antenna is launched this signal with form of electromagnetic wave;
(6) end process.
In the middle of practical application, suppose that mobile device of the present invention is mobile phone, this mobile phone is used in combination with vehicle-mounted radio system, promptly uses mobile phone to play music of the present invention, uses vehicle-mounted radio system to carry out signal then and receives broadcast, and its concrete steps are as follows:
At first, the voice signal in the mobile phone is converted into the electromagnetic wave signal that antenna can be received;
After then selecting frequency through tuner, select the radio signals that will receive, the signal that accesses is sent by antenna end after amplifying through high frequency;
Simultaneously, in vehicle-mounted radio, a local oscillator is arranged, produce one with the much the same local oscillation signal of receive frequency, it produces difference frequency with the received signal mixing, and this difference frequency is exactly an intermediate-freuqncy signal;
Intermediate-freuqncy signal is amplified through frequency-selecting of intermediate frequency again, and then detection, and just reduction has obtained original audio signal;
Audio signal just can be delivered to the sound equipment loudspeaker plays by after the power amplification.
See also shown in Figure 3 again, after the mobile phone end is opened the FM emission function, the frequency range of interface display emission for example is 92MHz, show that then the inner frequency modulation transmitting chip that is provided with of this mobile phone is converted into the electromagnetic wave signal that frequency is 92MHz with the MP3 music of storage by FM frequency modulation, at this moment, it is 92MHz that radio reception equipment is adjusted receive frequency, just the music of mobile phone the inside can have been play by radio reception equipment tuning sound.
Need to prove simultaneously, major technique thought of the present invention is as a source of sound output system independently with mobile device, audio signal is converted into electric wave signal, receive and be reduced to voice signal by receiving terminal by the FM receiver more at last, play back by the high-quality sound equipment, realized the personal mobile phone music sharing.But because some local radio stations are many, so the FM reflector need be set to a distant frequency range from existing radio station, to avoid common FM broadcast band, avoiding receiving conflict influences acoustical quality.
In addition, so about about 10 meters of transmitting boundary of mobile device of the present invention., in this effective range, as long as the FM emission function and the playing back music of user's starting hand-set, the music of mobile phone not only can be play by on-vehicle acoustic apparatus, and, if other companion's mobile phone has the FM receiving function, so, can share this dazzling sensation with the companion.
Adopted and realized the devices and methods therefor that music is shared on the above-mentioned mobile device, because by in mobile device, being provided with a frequency modulation (FM) transmitter module, thereby the music of playing in the mobile device can be launched by FM frequency modulation, be equivalent in the middle of everybody, form a little radio station, and after utilizing the high-fidelity power amplifying device to amplify after other radio reception equipment reception, play back, thereby can reach the purpose that music sources is shared; Simultaneously when driving, music in the mobile device is launched by FM, and use vehicle audio to receive then and play, the all people on the automobile can hear beautiful music like this, also reduced because of the band earphone simultaneously and can't hear the danger that sound is caused outside the car, thereby reached and not only shared happy, but also safing effect, and it is convenient and swift to operate, safe and practical, stable and reliable working performance, environmental protection, the scope of application are comparatively extensive, all bring great convenience for people's work and life.
In this specification, the present invention is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
