Fig. 2 is a circuit connection diagram of the present utility model.
Embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is described in further detail below in conjunction with specific embodiment and accompanying drawing:
Referring to Fig. 1～2, referring to Fig. 1～2, a kind of vehicle mounted multimedia AV device, include the multimedia file storer 7 and the LCDs 6 of storage music and video, described multimedia file storer 7 and LCDs 6 connect with the central processing unit 1 with speech identifying function, this central processing unit 1 also connects with vocoder 3 and FM voice reproducing circuit 4, and vocoder 3 connects with FM voice reproducing circuit 4 and microphone 5.Central processing unit 1 also connects with bluetooth baseband processing IC 2, and described bluetooth baseband processing IC 2 connects with FM voice reproducing circuit 4 and another microphone 51.FM voice reproducing circuit comprises the FM frequency-modulated transmitter, and this FM frequency-modulated transmitter connects with automobile audio FM system wireless.
Central processing unit adopts AK322X and family chip thereof, pin A1～the A9 of central processing unit is connected with the voice reproducing circuit, pin B1, B2, B3 connect with vocoder 3, pin B4, B5 connect with power management and battery module, pin B6～B9 and bluetooth baseband processing IC link, pin C1～C5 connects with the multimedia file storer, and pin C6～C9 connects with LCDs.Described FM voice reproducing circuit comprises the FM frequency-modulated transmitter, and this FM frequency-modulated transmitter connects with automobile audio FM system wireless.In addition, described central processing unit adopt have a speech identifying function have the processor of ARM7, ARM9 or ARM11 kernel based on the flush bonding processor IC of frameworks such as frameworks such as ARM, MIPS, X86 or other.
The described vocoder of the utility model device, bluetooth baseband processing IC and FM frequency-modulated transmitter are existing ripe device.In addition, the utility model device also is provided with power switch, reset switch and earphone jack and data-interface.
Audio-visual in order to realize voice control or free online multimedium, the user says by microphone needs playing back music or image, after microphone picks up voice messaging, convert the digital signal that central processing unit can be discerned to through vocoder, central processing unit output steering order, from the multimedia storer, transfer and get song title or image name or the singer's name or the publisher of answering mutually, the playout software of installing by central processing unit self carry out audio frequency and video compile separate after, raise one's voice and liquid crystal display plays back by FM voice reproducing circuit.
Use this device to realize voice control hand-free call, at first through being arranged so that the bluetooth cellular phone of human pilot matches.When the mobile phone of human pilot was received the signal of calling, the bluetooth baseband processing IC was sent to the voice reproducing phone to the signal that receives, and the voice reproducing circuit switches to automobile audio quiet, and the signal of incoming call will play back from fm stereo radio.After human pilot is heard incoming telephone signal, without the hands-on mobile phone key, can directly say the order that receives calls, voice command is delivered to vocoder after by the microphone collection, after being encoded, the sound operation signal delivers to central processing unit, finish speech identifying function by central processing unit, and send instruction according to the user and carry out control corresponding.After central processing unit identifies " answering " order, by the internal control interface, connect the bluetooth talking path, the conversation voice in the bluetooth passage is broadcasted by the loudspeaker that device carries, perhaps, use the sound equipment passage of the FM receiver of vehicle to broadcast by the FM modulation module on the device.
The utility model device increases speech recognition controlled and playing speech on demand function on the basis that keeps existing vehicle-mounted audio/video device button operation, come the control operation corresponding function by sound, convenient and swift, increased the ease of use and the modish property of vehicle-mounted audio/video device greatly.
