One music control module, the digital music data that reads in the Winchester disk drive provides broadcast;
One wireless transmitting unit, with digital music that the music control module broadcasted in addition modulation become wireless signal, utilize the frequency modulation function of automobile audio to receive and play for the user.
Described automobile audio hard disc player is characterized in that: this music control module comprises:
One harddisk wire-arranging connects this Winchester disk drive with the transmission of giving information;
One hard disk interface chip reads the data of this hard disk internal memory;
One digital music decoding unit, the digital music data that this hard disk is read converts to for the music signal of playing.
Described automobile audio hard disc player is characterized in that: this wireless transmitting unit is a frequency modulation radio road, with digital music that the music control module was broadcasted in addition modulation become wireless signal, utilize the frequency modulation function of sound equipment to receive and play for the user.
Described automobile audio hard disc player is characterized in that: this wireless transmitting unit is an amplitude modulation radiating circuit, with digital music that the music control module was broadcasted in addition modulation become wireless signal, utilize acoustic function to receive and play for the user.
Described automobile audio hard disc player is characterized in that: more comprise a display screen and an action button group, the demonstration of the related data when choosing and playing for the demonstration user.
Described automobile audio hard disc player is characterized in that: more comprise a Digiplex, utilize the remote control selected songs for the user.
Described automobile audio hard disc player is characterized in that: this Winchester disk drive more comprises a shell, and this shell is provided with the socket that is connected with computer I/O.
The invention has the advantages that:
Provide the user can be, and be carried on and connect automobile audio on the car it is play, use solving the happy restriction and inconvenience of choosing broadcast on the car a large amount of music information unloadings, and operation very just property, safety.
Below, cooperate graphic detailed description to introduce specific embodiments of the invention now as back:
