Embodiment
Core concept of the present invention is: add FM frequency modulation transmitter module and increase the vehicle-mounted pattern that mobile phone is set in mobile phone, when mobile phone enters vehicle-mounted pattern, voice-frequency channel in the mobile phone can automatically switch to FM emission path, the audio signal of the correspondent that will converse with the user by FM frequency modulation transmitter module sends by the frequency that the user sets, and receives and plays in corresponding band by the FM playback equipment simultaneously.
Among the present invention, described FM playback equipment can be a vehicle-mounted radio, also can be common broadcast receiver.Be that vehicle-mounted radio is that example describes in detail with the FM playback equipment below.
The prerequisite that the present invention realizes is: FM frequency modulation transmitter module is set in mobile phone, is used for audio signal is sent by the frequency that the user sets, and the vehicle-mounted pattern of mobile phone is set; And mobile phone has hand-free function.Further describe below in conjunction with specific embodiments and the drawings.
Fig. 1 is the realization flow schematic diagram of vehicle mounted call method among the present invention, and as shown in Figure 1, method of the present invention may further comprise the steps:
Step 101: when the user is in the driving state, the mobile phone setting that is provided with FM frequency modulation transmitter module is entered vehicle-mounted pattern, make mobile phone be in vehicle-mounted holding state, simultaneously vehicle-mounted radio is set to and the corresponding frequency range of the setpoint frequency of mobile phone.
Step 102: mobile phone starts FM frequency modulation transmitter module automatically, promptly starts FM emission path.
Step 103: mobile phone switches to FM emission path with voice-frequency channel, and concrete changing method is a prior art, repeats no more here.
Step 104: as the phone incoming call, when the user converses, FM frequency modulation transmitter module will with the other side's of user's communication audio signal, the audio signal of promptly receiving sends by predefined frequency.Wherein, frequency can independently be set by the user, and concrete setting-up time does not limit, can be before using vehicle-mounted pattern by the user, and autonomous setting or change in mobile phone at any time.
Here, how audio signal is belonged to existing known technology by the setpoint frequency transmission, repeat no more herein.
Step 105: the user utilizes vehicle-mounted radio, is setting the audio-frequency information of frequency range reception with the other side of user's communication, and is listening to by car audio system, simultaneously, by the hand-free function of mobile phone, realizes both sides' conversation.
Certainly, when described method also has been applicable to the cell phone incoming call incoming call incessantly, as long as when user's mobile phone is set to vehicle-mounted pattern, no matter the phone incoming call still is a phone is breathed out, as long as the user converses, can outwards send by FM frequency modulation transmitter module with the other side's of user's communication audio signal, the user can listen to by vehicle-mounted radio.And, in vehicle-mounted pattern, no matter which kind of operation the user carries out, carry out listening to of audio frequency as long as use voice-frequency channel, can outwards send by FM frequency modulation transmitter module, and answer by vehicle-mounted radio, such as: the user uses mobile phone to listen to mp3 etc., also can realize by said method.
In the practical application, used radio reception and the equipment of playing also are not limited to vehicle-mounted radio and car audio system, so long as can receive the audio signal of the setpoint frequency that FM frequency modulation transmitter module sent, and the FM playback equipment that can play all can be finished vehicle mounted call of the present invention, for example the user also can use common broadcast receiver to carry out the reception broadcast of audio signal, and processing procedure is on all four.
Fig. 2 is the structural representation of realization vehicle mounted call device of the present invention, as shown in Figure 2, this device comprises that pattern is provided with module 210, signal receiving module 220, audio frequency handover module 230, FM frequency modulation transmitter module 240, hand-free call module 250, signal transmitting module 260, music playing module 270 and FM playback equipment 280, wherein
Pattern is provided with module 210, is used to be provided with vehicle-mounted pattern, and under vehicle-mounted pattern, pattern is provided with module 210 and transmits control signal to audio frequency handover module 230, signal receiving module 220, FM frequency modulation transmitter module 240 and hand-free call module 250.
Audio frequency handover module 230 is used for receiving mode the control signal that module 210 is sent is set, and according to the signal of receiving voice-frequency channel is switched to FM emission path.
FM frequency modulation transmitter module 240 is used to the pattern of receiving the control signal that module 220 is sent is set, and starts FM emission path, afterwards, when the user uses voice-grade channel to carry out listening to of audio frequency, audio signal is outwards sent by predefined frequency.
Wherein, frequency can independently be set by the user, and concrete setting-up time does not limit, can be before using vehicle-mounted pattern by the user, and autonomous at any time the setting or change.
Hand-free call module 250 is used for receiving mode the control signal that module 210 is sent is set, and starts the hand-free call function, afterwards, when the user converses, receives user's audio signal and audio signal is sent to signal transmitting module 260;
Wherein, music playing module 270 is optional module.
In actual applications, module 210～270 can be arranged in mobile phone, when the user is provided with module 210 by pattern, when mobile phone is set to vehicle-mounted pattern, pattern is provided with module 210 and transmits control signal to signal receiving module 220, FM frequency modulation transmitter module and hand-free call module 250 simultaneously, starts above-mentioned three modules; Meanwhile, pattern is provided with module 210 and also transmits control signal to audio frequency handover module 230, starts audio frequency handover module 230, and voice-frequency channel is switched to the emission path; Afterwards, when the user converses, the other side's of signal receiving module 220 receptions and user's communication audio-frequency information, send to FM playback equipment 280 by FM frequency modulation transmitter module 240, for example vehicle-mounted radio is play, user's audio-frequency information then receives by hand-free call module 260, and sends to the other side with user's communication by signal transmitting module 260, thereby has realized vehicle mounted call.
In addition, when mobile phone is in vehicle-mounted state, and the user is not when conversing, and the audio signal of the music of playing in the music playing module 270 also can send to FM playback equipment 280 by FM frequency modulation transmitter module 240 and play.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
