Description
Technical field
This product relates to a kind of vehicle audible device, relates in particular to a kind of MP3 vehicle audible device of wireless connections.This device is realized wireless connections by the FM broadcast receiver.
Background technology
Traditional automobile audio VCD and DVD generally comprise: FM, AM broadcast receiver, cartridge player, the CD that this all depends on broadcasting and can not change.Wherein, the cassette type tape duplicates and waits shortcoming slowly owing to weak effect, now progressively be eliminated, and VCD and DVD player can realize result of broadcast preferably, but also have shortcomings such as the scuffing of vibrations and video disc causes that broadcast distortion and song can't be edited.
The utility model content
Problem to be solved in the utility model provide a kind of play the distortion factor low, can not be because of the MP3 vehicle audible device of the wireless connections of vehicle vibration influence result of broadcast.This device is realized wireless connections by the FM broadcast receiver.
For addressing the above problem, the utility model adopts following technical proposals: it is made up of the vehicle-mounted radio and the MP3 player that are installed in the car; Also be provided with the power supply that uses for acoustics, the button that is used to control, audio signal is modulated to the FM frequency that adapts with vehicle-mounted radio operating frequency point and the FM reflector of launching, the PC that is used to control whole system and MP3 decoding, the digital music signal of PC output is reduced into the DA transducer of analog signal at Che Nei; Described MP3 player is connected with lead with PC, and described PC is connected with lead with the DA transducer, and described DA transducer is connected with lead with the FM reflector.Show current play parameter intuitively for convenient, this device is provided with LCD.
For depositing the more happy data of multitone, this device is provided with flash memory.
For making things convenient for the use of acoustics, described power supply adopts chargeable battery, and described battery is equipped with line charger and onboard charger, indoor and can charge onboard.
Operation principle of the present utility model is: the MP3 player is downloaded and music editing by the USB mouth of PC, go out music signal by the MP3 player plays, be modulated to the operating frequency point of FM receiver through the FM transponder, after vehicle-mounted radio receives, play by the sound equipment on the automobile.
The utility model have storage fast and flexible, transmission speed fast, play the distortion factor low, can not be because of characteristics such as vibration influence broadcasts.
Description of drawings
Fig. 1 is the fundamental diagram of the MP3 vehicle audible device of a kind of wireless connections of the utility model.
Embodiment:
With reference to shown in Figure 1, the utility model mainly is made up of vehicle-mounted radio and MP3 player; Also be provided with power supply, button, CPU, DA transducer, LCD, FM reflector, flash memory in addition; CPU mainly carries out the control of whole system and the decoding of MP3, flash memory is used to deposit song data, can show current play parameter intuitively on the LCD, ROM is used to deposit control program, the FM reflector is used for audio signal is modulated to the FM frequency, and launch, the DA transducer is reduced into analog signal with the digital music signal of CPU output, and delivers to the FM reflector and launch.
This device built-in lithium battery can use by cycle charging.And configuration line charger and onboard charger are indoor and can charge onboard; And therefore the function that can play when possessing charging uses vehicle power can continue to play onboard.
After the download of USB mouth and music editing of MP3 player by PC, go out music signal,, after vehicle-mounted radio receives, play by the sound equipment on the automobile through the operating frequency point of FM transmitter modulation to FM receiver by the MP3 player plays.
