Abstract
This invention involves a method and system of a wireless broadcast of mobile phone audio broadcast. It could be used to launch the audio signal of mobile phones to the equipment with tunable reception function and then broadcast it. The phone has a module with the tunable launching function. Users could control this module to tunably launch the audio signal through the operation of mobile phone menu, and then the tunable reception equipment would accept the above referred launched audio signal and broadcast it. The technique program of this invention could effectively avoid the defects of shorter wired transmission distance and tedious routing. Using the way of wireless, audio signal output by the mobile phone could be wirelessly emitted through the special circuit module in the mobile phone. It has wide use range. For example, it could be used to hold the telephone conference, or listen to MP3 music using FM stereo inside the car, or appreciate family or small group music and listen to programs.
Description
[technical field]
The present invention relates to a kind of wireless playing method and system of handset audio.
[background technology]
At present, mobile phone has become communicator commonly used in people's life.And along with the continuous development of multimedia technology, also increased auxiliary functions such as for example MP3 broadcast on the mobile phone, made it become a portable recreation terminal.For the user, when using mobile phone, it is hand-held and situation that need listen to mobile phone sound exists to have inconvenience sometimes, as receiving calls when driving or music appreciating, carrying out videoconference etc. when only mobile phone being arranged.
Though some mobile phone products has designed hands-free the setting and achieved the above object, because the mobile phone volume restrictions, its speaker volume is less, and effect is not fine.Therefore, the MP3 of existing mobile phone and speech are play, and for reaching the purpose of the effect that amplifies, normally amplify by being wiredly connected to audio frequency amplifier.But there is the restriction of spatial obstacle thing and wire length in the mode of wired connection, and is not easy to use.
Therefore, wireless playing method and the system that a kind of handset audio must will be provided arranged.
[summary of the invention]
Technical problem to be solved by this invention is to provide a kind of wireless playing method and system of handset audio.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of radio play system of handset audio is used for audio signal with mobile phone and is emitted to the equipment with tuning receiving function and plays.This mobile phone inside is provided with one and has the module of tuning emission function, the user is by controlling the tuning emission that this module is carried out audio signal to the operation of cell phone function menu, received the described audio signal that is launched and play by the equipment with tuning receiving function.
Technical scheme of the present invention has been avoided the short and lengthy and tedious defective that connects up of wire transmission distance effectively, adopts wireless mode, with the audio signal of mobile phone output, goes out by the specialized. circuit modules wireless transmission in the mobile phone.It is of many uses, can carry out as videoconference, utilize in the automobile FM sound equipment to listen to MP3 music, family or the groupuscule Music Appreciation in the mobile phone and listen to program etc.

Fig. 2 is a mobile phone of the present invention and the block diagram that is connected of FM transmitter module.
Fig. 3 is the chip line graph between mobile phone of the present invention and FM transmitter module and the transmitting antenna.
[embodiment]
The invention will be further described below in conjunction with accompanying drawing.
See also Fig. 1, be realization block diagram of the present invention.The wireless playing method of handset audio of the present invention and system adopt wireless mode, in mobile phone, increase special-purpose radio transmitter module, and the audio signal of mobile phone output is emitted to by this wireless module can receives described wireless signal and it is carried out the playing device that audio frequency amplifies.Thereby the audio signal that makes mobile phone can be received in 50 meters left and right sides scopes and amplify broadcast, with the purpose that realizes that many people listen on a large scale.
The wireless playing method of handset audio of the present invention and system control the radio transmitter module of setting up in the above-mentioned mobile phone by the cpu chip of mobile phone itself, thereby make the user audio signal in the mobile phone can be carried out wireless transmission.And for it is provided with special Chinese actions menu, easy and simple to handle.
See also Fig. 2, consider the ease for use of device, radio transmitter module of the present invention adopts FM (tuning) transmitter module comparatively commonly used.The audio signal of mobile phone inside is divided into left and right acoustic channels (L/R) audio frequency, when the user needs, can signal be modulated by the control of mobile phone CPU,, by antenna it is transmitted near the receiver by the FM transmitter module in the machine.
At above technical though, FM transmitter module of the present invention adopts NS73M stereo transmission module, and Fig. 3 is the chip line graph between mobile phone of the present invention and FM transmitter module and the transmitting antenna.
In sum, the present invention is when satisfying the mobile phone proper communication, has increased MP3 audio frequency FM modulation transmitter, thereby MP3 audio signal in the mobile phone can be transferred in the receiving equipment wirelessly.It can adopt the menu of conventional mobile phone to control, and promptly sets up the function corresponding option in cell phone function menu, special function button also can be set on mobile phone carry out, this be general mobile phone can't possess.
The wireless playing method and the system of handset audio of the present invention are of many uses, can carry out as videoconference, utilize in the automobile FM sound equipment to listen to MP3 music, family or the groupuscule Music Appreciation in the mobile phone and listen to program etc.
