Description
1, technical field:
The utility model relates to a kind of power amplifier with playing function.
2, background technology:
Along with popularizing gradually of the high speed development of audio visual technology and network technology, serve as that the online music program of form of transmission and record is more and more abundanter with MP3 and MP4, appreciating MP3 music and MP4 video at present has two kinds of approach: 1) directly output is on computers play; 2) download in the portable player and play.Because MP3 and MP4 handle through overcompression, its compressibility is all higher, comparatively being fit to powerful high-fidelity plays, but the power of the audio frequency of portable player of existing MP3 and the portable player of MP4 output is all lower, be difficult to obtain the good sound quality effect, and the price of portable player of MP3 and the portable player of MP4 is all higher, and existing power amplifier can not be play-overed MP3 and MP4.Also occur the multi-media player that some can play MP3 on the market, but volume is bigger, it is not too convenient to use, and power consumption is bigger.
3, summary of the invention:
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of power amplifier with playing function.
The utility model is achieved by the following technical solution: it comprises the power amplifier module, the power amplifier module is provided with Audio output port, it also comprises MP3 or MP4 functional module, the audio output of MP3 or MP4 functional module is connected with the audio input end of power amplifier module, also is provided with USB (universal serial bus) on MP3 or the MP4 functional module.
Above-mentioned described MP3 or MP4 functional module are connected with the memory card reading device, in order to read the storage data in the memory card and to be transported to MP3 or the MP4 functional module is handled and exported.
Also be provided with the VT mouth on above-mentioned described MP3 or the MP4 functional module.
Above-mentioned described power amplifier module and MP3 or MP4 functional module can be incorporated into the audio amplifier the inside.
The utility model compared with prior art has following advantage: 1) volume is less, low price, and power consumption is less; 2) by power amplifier the audio frequency of video files is carried out the broadcast of high-fidelity, acoustical quality is preferable; 3) can use very convenient by the capacity of memory card extension storage.
4, description of drawings:
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
Fig. 1 is a structure principle chart of the present utility model.
5, embodiment:
As shown in Figure 1, the utility model comprises power amplifier module 1, power amplifier module 1 is provided with Audio output port 2, it also comprises MP3 or MP4 functional module 3, the audio output of MP3 or MP4 functional module 3 is connected with the audio input end of power amplifier module 1, also be provided with USB (universal serial bus) 4 on MP3 or the MP4 functional module 3, also be provided with VT mouth 5 on MP3 or the MP4 functional module 3, MP3 or MP4 functional module 3 also are connected with memory card reading device 6, in order to read the played data in the memory card and to be transported to MP3 or MP4 functional module 3 is handled and exported.
Above-mentioned described power amplifier module 1 and MP3 or MP4 functional module 3 can be incorporated into the audio amplifier the inside.
Principle of work of the present utility model is: be connected with computing machine 7 by USB (universal serial bus) 4, in computing machine 7, the user is needed the audio/video file of typing to copy storage in MP3 or the MP4 functional module 3 to, wherein can delete and operation such as typing the audio/video file of storage in MP3 or the MP4 functional module 3 by computing machine 7, MP3 or MP4 functional module 3 can be read in audio/video file in the memory card 8 to the audio/video file of its storage or reading device 6, decode, processing such as digital-to-analog conversion, after the sound signal of output is amplified by power amplifier module 1, be delivered in audio amplifier or the loudspeaker by Audio output port 5 and export; The vision signal of output is transported in the display device by VT mouth 5 and shows.
