Further, the described USB slot coupling USB of mechanism or min-USB connector.
Compared with prior art, the utility model operates hommization more, take that to improve that user experiences be core, strengthens human-computer interaction.
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the audio amplifier the utility model proposes is described in further detail.
Refer to Fig. 1, Fig. 1 is the electrical block diagram of audio amplifier of the present utility model.The audio amplifier of the present embodiment comprises housing and is arranged on the integrated circuit that comprises voice recognition unit in housing, wherein, described integrated circuit comprises arithmetic processor, the A/D converter being connected with arithmetic processor, memory cell and the microphone, operational amplifier and the filter that connect in turn, wherein, memory cell includes SD memory card module, FLASH, SDRAM.Arithmetic processor can dsp processor or the processor of FPGA or ARM, also can with the chip of other SOC realize all can, also can adopt according to actual needs general CPU to realize functional processor in conjunction with software.
In the present embodiment, described filter can adopt frequency overlapped-resistable filter to realize.On described audio amplifier, be also provided with loud speaker and push-button unit, push-button unit can be controlled the various functions of audio amplifier mechanically.
Described audio amplifier also comprises the push button that is arranged on audio amplifier top, in order to according to user's touch, gathers touch signal, and starts corresponding units work according to the indication of touch signal.During use, user only need to touch the push button at top, the operation that audio amplifier can point out you to do.Such as, touch the push button at top, start voice control function, now, user passes through voice mode, as say the name of certain song, this audio amplifier can start the integrated circuit of voice recognition unit, collect user's sound, user's one's voice in speech is carried out filtering and carries out signal processing, and the music libraries of storing in this audio amplifier or search for this song title by network connected reference in the music libraries in long-range high in the clouds, if store in audio amplifier this locality, can play immediately this song, if play by high in the clouds, can point out user to select online play or download while putting or download to local audio amplifier and play again etc.
Phonetic function can also arrange a lot of functions, such as the instruction of the volume of controlling audio amplifier broadcasting can be set, user only needs the instructions such as " more greatly " " a little bit smaller ", all instructions of the rapid completing user of audio amplifier meeting, the volume of music is heightened or turned down, need not in person go to the size of adjusting mechanically volume on audio amplifier.Certainly selection music can also be set, as select next or a upper head, or the function such as fast forwarding and fast rewinding.
On described housing, be also provided with a display unit, in order to show interactive information, this display unit can be LCD display, or other flat-panel monitors with touch-control interactive function, in order to user, can in this display unit, input instruction according to systems soft ware, realize mutual.
On described housing, be also provided with SD card slot mechanism, described SD memory card module is stored in described SD card slot mechanism, and user can extract this SD memory module at any time, convenient copy, transmission data or data.
On described housing, be also provided with USB slot mechanism, in order to connect USB interface and to carry out transfer of data or communication, the common general USB connector interface of described USB slot mechanism's coupling, also can be set to mate min-USB connector.This audio amplifier can or be conducted interviews with external mechanical or systems exchange data, such as be connected to PC end or mobile phone terminal by USB line, can be by the song direct copying of PC end or mobile phone terminal to audio amplifier, or play music at PC end or mobile phone terminal, all can use this USB line, by audio amplifier, play etc.
The technique effect of intelligent sound box is in sum as follows:
1, simple to operate, without manual command.
2, the selection of music and adjusting are more followed one's bent, and make user can more independently enjoy music.
3, audio amplifier is used and is no longer confined to narrow space scope, and can extend to whole indoor.
4, human-computer interaction provides wide development space for realizing modern house intelligent integral, for making the audio-visual environment of Domestic two, provides technical support.
Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model utility model.Like this, if within of the present utility model these are revised and modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model is also intended to comprise these changes and modification interior.
