Abstract
The utility model discloses a cell phone with radio FM transmitting function and aims to provide the cell phone with simple structure and the cell phone is capable of transmitting the receiving voice and the playing music to an automobile or other general FM receiving sonic equipment by cordless FM mode. Users can share the music in the cell phone conveniently. The utility model provides users a more convenient hands-free mode to make the cell phone even more convenient and practical. The utility model contains a shell and a circuit portion, wherein the circuit portion contains a microprocessor, a memorizer, a radio frequency circuit of the cell phone, a buzzer, a clavier die block, a liquid crystal display and a power supply which are original circuits of the cell phone. The circuit portion also contains an increased FM modulating transmitting circuit and a corresponding launching aerial. The FM modulating transmitting circuit is connected with the original microprocessor of the cell phone by a serial bus or a paralleling controlling circuitry. The FM modulating transmitting circuit is connected with an audio circuitry for media playing and an audio circuitry for voice receiving of the original cell phone by an audio circuitry.
Description
Technical field
The utility model relates to a kind of mobile phone, in particular, relates to and a kind ofly can be wirelessly transmitted to automobile or other to sound such as music, speeches by FM and have mobile phone in the stereo set commonly used that FM receives
Background technology
At present cell-phone function makes rapid progress, and the mobile phone that has a multi-media player function also has a variety of, uses mobile phone to bring very big convenience and enjoyment to people.But this mobile phone with multi-media player function can not be with sound or the transmission of music signal wireless transmission, plays back by other stereo set, has brought very big inconvenience to the consumer.
For example, the driver who is driving wants to listen attentively to the music that mobile phone is play, and can only pass through earphone.When earphone stops up driver's ear, make the driver receive slow, blunt that extraneous information becomes, be easy to cause traffic accident.If the music wireless of can the handle machine sowing putting emission transmission receives by vehicle-mounted radio, the music play of mobile phone plays back by broadcast receiver so, and it is convenient not only to make the driver listen attentively to music, the more important thing is and has reduced traffic accident.In addition, when mobile phone has incoming call, the speech of cell phone incoming call can be transferred to stereo set in the car by this wireless mode, provide a kind of hands-free way more easily to the driver.
Again for example, the music of mobile phone broadcast at present can only be used for the individual and appreciate, be difficult to play back and other people shared music by stereo set, if mobile phone can be with music by being wirelessly transmitted to the broadcast receiver in the stereo set, just can be very easily share the music that mobile phone is play in any occasion that corresponding stereo set arranged and other people, can bring to the cellie to greatly facilitate and enjoyment, the mobile phone that has this wireless transmission function so will be subjected to user's expectation and welcome.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, a kind of not only simple in structure but also music wireless emission transmission of can the handle machine sowing putting is provided, makes the mobile phone that has multi-media player function convenient, practical.
Another purpose of the present utility model is: have the mobile phone of this wireless transmission function, can provide a kind of more convenient hands-free way to the client in the occasion that corresponding stereo set is arranged.
In order to solve the technical problem of above-mentioned existence, the utility model can adopt following technical scheme:
The utility model comprises housing and circuit part.Wherein, circuit part comprises: the original circuit of mobile phone such as microprocessor, memory, mobile phone radio frequency circuit, buzzer, Keysheet module, liquid crystal display, power supply.Described circuit part also comprises FM modulation transmitter and the corresponding transmitting antenna that increases newly, this FM modulation transmitter is connected with the microprocessor of former mobile phone by universal serial bus or parallel control line, and links by the media play voice band line of voice band line and former mobile phone and the voice band line of speech reception.
The frequency range that described wireless FM modulation circuit is launched is 70.0-120.0MHZ.
Described wireless FM modulation circuit can be selected IC such as BH1415 or BH1417 for use.
The beneficial effects of the utility model are: 1, because the music wireless of can the handle machine sowing putting emission transmission, it is convenient, especially even more important to the driver who drives to make the user listen attentively to music, has reduced generation traffic accident possibility; 2, can provide a kind of more convenient speech hands-free way for the cellphone subscriber; 3, with mobile phone to play music by being wirelessly transmitted to stereo set, can be easily share the music 4 that mobile phone plays, the connected mode of having simplified hands-free or sound equipment any occasion that corresponding stereo set arranged and other people;
Description of drawings
Fig. 1 is the circuit block diagram of a kind of embodiment of the utility model.
Fig. 2 is the circuit block diagram of the another kind of embodiment of the utility model.
Below by embodiment and accompanying drawing the utility model is described in further detail.
Embodiment
BH1415 IC can be implemented in the arbitrary frequency emission of 70.0-120.0MH, and resolution is 0.1MHz.
Cell-phone microprocessor is by serial bus control BH1415, and BH1415 can automatically lock the frequency of radio station of microprocessor appointment, realizes music wireless frequency modulation (FM) emission function.The user is set to the frequency identical with radiating circuit with the broadcast receiver in the sound equipment, just can receive the audio signal that radiating circuit sends out, so, the voice signal that music that mobile phone is play or mobile phone receive just can play back by vehicle audio or other corresponding stereo sets, realizes sharing and speech hands-free of music.
BH1417 IC can be implemented in the 70.0-120.0MH scope and launches on 16 fixing frequencies.
Cell-phone microprocessor is by parallel control line traffic control BH1417, and BH1417 can automatically lock the frequency of radio station of microprocessor appointment, realizes music wireless frequency modulation (FM) emission function.The user is set to the frequency identical with radiating circuit with the broadcast receiver in the sound equipment, just can receive the audio signal that radiating circuit sends out, so, the voice signal that music that mobile phone is play or mobile phone receive just can play back by vehicle audio or other corresponding stereo sets, realizes sharing and speech hands-free of music.
