In fig. 1, a smartphone; 2. a Bluetooth module; 3. a waveform memory unit; 4. a waveform decoder; 5. a sound control unit; 6. vehicle-mounted sound equipment.

Detailed Description

according to the invention, after the Bluetooth of the smart phone 1 is connected with the vehicle-mounted Bluetooth, the song played inside the smart phone corresponds to an electromagnetic wave signal, the multimedia receiving sub-signal is decoded by the waveform decoder 4, and the decoded signal is input to the vehicle-mounted sound through the multimedia processor to generate resonance to form sound. In the whole vehicle working process, a multimedia waveform memory unit is added in multimedia. Every song in the mobile phone corresponds to electromagnetic waves with different wavelengths and frequencies, and the song name can be memorized by memorizing the wavelength of the electromagnetic waves.

Specifically, as shown in fig. 1, the invention includes that songs in a smart phone 1 of a driver are compiled into electromagnetic wave signals with different waveforms and sent to a waveform memory unit 3 of a playing system through a bluetooth module 2, the waveform memory unit 3 sends the electromagnetic wave signals of the songs with different waveforms to a sound control unit 5 through a waveform decoder 4, and the sound control unit 5 controls a vehicle-mounted sound 6 to vibrate to generate sound.

When the playing time t1 of playing the music by the player is far shorter than the total playing time t of the music, the waveform memory unit 3 memorizes the music as the music disliked by the driver, and the following smart phone 1 can automatically filter the disliked music in the mobile phone player after being connected with the vehicle-mounted entertainment system again.

When the playing system is in the random playing mode and the song starts, the waveform of the dislike song in the waveform memory unit 3 is compared with the waveform which is played at the beginning, and if the played song is identified to be whether the driver dislikes the song, the sound control unit 5 skips the current song and enters the next song.

As shown in fig. 2, when the player plays song B, which is not a favorite song of the driver, the driver presses the fast forward button on the steering wheel or the fast forward button on the multimedia touch screen. At this time, the playing of the disliked song B which cannot be completed is directly switched to the next song, and since the disliked song B is not completely played, the monitoring can be performed through time. The playing time of the downloaded songs in the mobile phone is fixed, assuming that the total playing time of the songs B is t, when the player plays the songs B, the driver can go to the next played song through a fast forward button due to the disliked songs, and at the moment, the playing time t1< < t of the songs B is memorized by the multimedia memory unit, and the fact that the songs are not liked by the driver is determined.

Through the technical means of the steps 1 and 2, when the driver is connected with the vehicle-mounted Bluetooth for the first time, the multimedia memory unit can memorize the name of the mobile phone Bluetooth and determine the dislike curved surface of the driver in the music playing process, and a foundation is established for automatically filtering dislike songs in the mobile phone player after the mobile phone is connected with the vehicle-mounted entertainment system again.

For dislike track filtering, we explain two forms of sequential playing and random playing of songs in real life.

In the sequential play mode, song B in fig. 2 is a dislike song, and in order to enable the subsequent player to automatically filter when playing song B, we need to memorize the waveform of the previous song a while identifying the dislike song in step 2. After the driver uses the mobile phone to connect with the vehicle-mounted Bluetooth player for the second time, when the song is played to the song A circularly, the waveform of the song A corresponds to the waveform of the song A in the memory one by one, and at the moment, the control unit controls the player to directly jump to the song C in the next song, so that the filtration of the dislike song B is realized.

In the random play mode, the waveform of the song A cannot be identified, but in the step 2, the waveform of the song B is memorized, when the song B in the random play mode starts, the waveform of the song B in the memory module corresponds to the waveform of the song B which is played at present, so that the song B is identified to be a non-favorite song of a driver, the control unit can directly skip the song B to enter the next song, and the filtering of the non-favorite song B in the random play mode is realized.

in summary, the first mobile phone is connected with the vehicle-mounted entertainment system, and is used for memorizing disliked songs and the previous song, and belongs to the memory stage for the first time; when the songs are circulated to the disliked songs again or the mobile phone is connected with the vehicle-mounted entertainment system for the second time, the system can filter the disliked songs according to the waveform memorized in the early stage, so that the driver can hear the favorite songs all the time when the driver uses the vehicle for the second time or the second time.

The invention is described above with reference to the accompanying drawings, and it is obvious that the specific implementation of the invention is not limited by the above-mentioned manner, and it is within the scope of the invention to adopt various modifications of the technical solution of the invention or to apply the technical solution of the invention to other occasions without any modification.
