Abstract
The utility model relates to a vehicular MP3 wireless player which comprises a peripheral storing device interface, a host machine, a music decoding functional module, a frequency modulating module and an output aerial. The host machine is connected with the peripheral storing device interface, and the music decoding functional module and the frequency modulating module connected in turn are installed inside a chip of the host machine. The output aerial is connected with the modulating module. The utility model adopts the scheme, so people can use a portable U disk to download and store MP3 songs. When the songs need to be played, the U disk is connected to the player through the USB interface of the utility model to play the MP3 songs. Simultaneously, the existing receiver in the vehicle can be used as a playback device because of the adoption of the wireless play, which completely realizes the solutions of miniaturization, convenience, energy saving, full-electron storage and full-electron play of vehicular MP3 wireless play.
Description
[technical field]
The utility model relates to a kind of wireless data playing device, particularly a kind of vehicular MP3 radio player.
[background technology]
When driving, people all like enjoying beautiful music, but when listening CD, and very inconvenient to the selection of song, must constantly buy the CD dish, and in CD dish, the song of oneself really liking is in fact with regard to one or two head; Vehicle-mounted CD is very high to dustproof shockproof requirements, the use cost height, and the life-span is short, is not desirable vehicle-mounted music product.Along with the propagation of computer network, the music of MP3 data layout is popularized in network world just rapidly, and increasing young man uses dapper MP3 player to replace traditional Walkman or discman.Along with the marketing scale that MP3 increases rapidly, people begin to consider to use vehicle mounted MP 3 in automobile audio.Though the online advantage that is loaded with free selected songs down because can only be from network by wired mode down-load music, like in automobile audio very difficult increase MP3 player.Wireless data transmission network also being arranged at present, but transmit with cellular network, cost an arm and a leg, is that institute of domestic consumer is unacceptable.
[summary of the invention]
The utility model has proposed a kind of vehicular MP3 radio player at the shortcoming of prior art, can overcome the defective of prior art.
The utility model is achieved like this:
A kind of vehicular MP3 radio player comprises the External memory equipment interface, main frame, music decoding function module, frequency modulation modulation module and output antenna; Main frame is connected with the External memory equipment interface, built-in music decoding function module and the frequency modulation modulation module that connects in turn of host chip, and the output antenna is connected with modulation module.
The utility model further comprises: host chip also is connected with the LCD display of the broadcast state and the various states in the control procedure that are used for showing MP3 simultaneously.
Between music decoding function module and modulation module, be connected with the sound signal input/output interface.
The employed power supply of the utility model is the power supply of cigar lighter in the automobile.
Described External memory equipment interface is USB interface, SD card or mmc card interface.
The utility model is by adopting such scheme, make and to download song with the Flash class memory device of the band USB interface of carrying or the memory device of other band USB interface with store M P3, when needing to play, be connected with player by USB interface of the present utility model, just can realize the broadcast of MP3.Simultaneously,, can utilize radio on the existing automobile, realize that fully miniaturization, portable, energy-conservation, full-electronic storage and full-electronic play the solution of vehicle mounted MP 3 radio play as tone playing equipment because adopt radio play.
[description of drawings]
Fig. 1 is a functional-block diagram of the present utility model.
Fig. 2 is a circuit diagram of the present utility model.
[embodiment]
Below in conjunction with drawings and Examples the utility model is further elaborated:
As depicted in figs. 1 and 2.The utility model comprises USB interface, and main frame is connected with USB interface, the built-in MP3 of host chip, electronic music decoding function modules such as WMA, WAV, and with the stereo FM mode of frequency regulation modulation module that is connected in turn, the output antenna is connected with modulation module.Host chip also is connected with LCD display simultaneously, is used for showing the broadcast state of MP3 and the various states in the control procedure.Between decoding function module and modulation module, be connected with the input of ordinary audio signal, output interface.The power supply that the utility model adopts is the power supply of cigar lighter in the automobile.
The MP3 song liked of DIY oneself can all leave the song that favorite is listened in the USB flash disk in to the greatest extent on computers.The USB flash disk that has the MP3 song with after vehicular MP3 radio player is connected, be inserted on the socket of cigar lighter in the car, press the switch connection power supply, player reads the data on the USB interface automatically, and the MP3 data on the USB interface are delivered to music decoding chip decoding be reduced to sound signal, can directly listen to the MP3 song with earphone by audio output jack herein; Sound signal also can be amplified the back to aerial emission by stereo FM mode of frequency regulation modulation.Idle frequency range is opened and transferred to automobile audio FM receiver in the car, transfer to automobile audio FM receiver same frequency, press play button, can listen to the MP3 song of oneself liking by frequency key.
Usb host controller in more than using can be expanded interfaces such as SD card, mmc card, does not change main application function, uses with the External memory equipment that adapts to distinct interface.With the flash dish of band USB interface or the electronic storage medium of other band USB interface is signal source, and MP3 song herein also can be other music formats such as WMA, data layouts such as WAV.
It is the music mode of the electromechanics combination of music signal storage medium with tape or CD dish etc. that the utility model product has thoroughly changed traditional, has realized that fully miniaturization, portable, energy-conservation, full-electronic storage and full-electronic play.
