The intelligent sound entertainment systems
Technical field
The present invention relates to automobile technical field, be specifically related to a kind of vehicle-mounted intelligent sound entertainment systems.
Background technology
No matter existing car audio system is traditional switch key control or advanced voice control, all needs the people initiatively to give an order and just can carry out.And along with the future development of automobile towards intellectuality, hommization, various automatic induction executive devices emerge in an endless stream, therefore, the vehicle audio entertainment systems of meeting perception car owner's mood and environment inside car atmosphere and then automatically operation meets people's demand more, also has good application prospect.
Summary of the invention
The invention provides a kind of intelligent sound entertainment systems, by the mood of passenger on the automatic sensing car and the environment in the car, automatically adjust the music categories that sound equipment is play, to adapt to passenger's mood and environment at that time.The audio entertainment system of this intelligence need not the user and sends instruction and just can realize automatically adjusting music type, builds to be fit to prevailing circumstances and the music atmosphere of mood at that time, more meets user's request.
Described intelligent sound entertainment systems comprises:
Inductor is installed on the safety strap, is used for perception and sends passenger's myocardial electrical signals;
Microphone gathers and sends the environment inside car sound;
Memory device is used for the music file that storage can be play, and wherein each music file is preset with music atmosphere classification;
Main control unit, receive described myocardial electrical signals and described environment inside car sound, search default myocardial electrical signals and environment inside car sound and the corresponding table of music atmosphere classification, obtain music atmosphere classification corresponding to current described myocardial electrical signals and described environment inside car sound, and the control vehicle audio is play the music file of the described music atmosphere classification in the described memory device.
Preferably, described main control unit also is arranged to, the broadcasting time of the music file that record is played, and when playing the music file of described music atmosphere classification, after sorting with the broadcasting time of the music file of described music atmosphere classification, play according to the order that broadcasting time is descending.
Described memory device is specifically as follows SD card, USB flash disk and/or on-vehicle host hard disk.Described SD card is connected by the SD mouth with described main control unit.Described USB flash disk is connected by USB interface with described main control unit.Described main control unit can be on-vehicle host.
Utilize intelligent sound entertainment systems provided by the invention, can in time perceive passenger's myocardial electrical signals, and find corresponding music atmosphere classification according to described myocardial electrical signals and environment inside car sound, and then play and fit opportune music file, need not the user and initiatively give an order just can build and be fit to prevailing circumstances and the music atmosphere of mood at that time, more meet user's request.
Description of drawings
Fig. 1 shows the intelligent sound entertainment systems structural representation that one embodiment of the invention provides.
The specific embodiment
Describe the present invention below in conjunction with drawings and the specific embodiments.
Fig. 1 shows the vehicle intelligent audio entertainment system structure that one embodiment of the invention provides, and this system comprises:
Inductor 102 is installed on the safety strap, is used for perception and sends passenger's myocardial electrical signals;
Microphone 105 gathers and sends the environment inside car sound;
Memory device 104 is used for the music file that storage can be play, and wherein each music file is preset with music atmosphere classification;
Main control unit 101, receive described myocardial electrical signals and described environment inside car sound, search default myocardial electrical signals and environment inside car sound and the corresponding table of music atmosphere classification, obtain music atmosphere classification corresponding to current described myocardial electrical signals and described environment inside car sound, and the control vehicle audio is play the music file of the described music atmosphere classification in the described memory device by loud speaker 103.
Wherein, described myocardial electrical signals and environment inside car sound and the corresponding table of music atmosphere classification can be as shown in following tables:
Myocardial electrical signals |
The environment inside car sound |
Music atmosphere classification |
First signal |
The first environment sound |
First category |
Secondary signal |
The second environment sound |
The second classification |
The 3rd signal |
The 3rd ambient sound |
The 3rd classification |
Can know, the myocardial electrical signals shown in the table, environment inside car sound and music respectively kind and the title of classification all can be changed, in the table only for schematically illustrating.Preset the classification of myocardial electrical signals, the classification of environment inside car sound, and they and the music corresponding relation of classification respectively when practical application, just can directly have been searched the music atmosphere classification corresponding with myocardial electrical signals and environment inside car sound like this.For example, described environment inside car sound can be divided into 3 classifications according to volume: strong, in, a little less than, described myocardial electrical signals can be divided into 3 classifications according to s-f: fast, slow, slow, then the combination of environment inside car sound and myocardial electrical signals at most can be to there being 9 kinds of music atmosphere classifications, can certainly be according to actual needs corresponding three kinds of music atmosphere classifications only, for example, classic, jazz and popular.
Certainly, the music file of storage has all preseted music atmosphere classification, so that described main control unit 101 can in time find the music file of required music atmosphere classification in the described memory device 104.
Further, described main control unit 101 also records the broadcasting time of each music file, when playing the music file of certain music atmosphere classification, at first find the music file of this all music atmosphere classifications like this, then according to the broadcast of sorting from more to less of their broadcasting time.May more meet user preferences owing to playing the high music file of frequency, therefore play according to the method the demand of can more being close to the users.
Described memory device 104 can be SD card, USB flash disk and/or on-vehicle host hard disk.Described main control unit 101 can be on-vehicle host.The SD card can be connected to described main control unit 101 by the SD interface like this.USB flash disk can be connected to described main control unit 101 by USB interface.
Above embodiment only is used for technical scheme of the present invention is described, is not limited to protection scope of the present invention.The modification that those skilled in the art can carry out technical scheme of the present invention or equal the replacement, and do not break away from the spirit and scope of technical solution of the present invention.
