Description
Technical field
This utility model relates to audio amplifier field, is specifically related to a kind of multimedia digital active loundspeakers system.
Background technology
Sound system refers to, with microphone, the acoustic signals of primary sound field sound is converted to the signal of telecommunication, and by certain requirement, the signal of telecommunication is passed through the process of some electronic equipments, the signal of telecommunication is reconverted into acoustic signals and resets by final speaker, and this whole composition from microphone to speaker is exactly sound system.
The most traditional audio amplifier is all as external playback equipment, uses function singleness, and when playing, power amplifier CD or DVD to be connected or computer could be play.This audio amplifier is only applicable to home theater or a certain fixed-site, uses and is relatively limited to, and source of sound input style is limited.And audio frequency output is mixed with high frequency, intermediate frequency and low frequency, detailed frequency dividing output do not carried out by conventional audio amplifier, affects very much the experience of user.
Utility model content
In view of this, the open a kind of multimedia digital active loundspeakers system of this utility model.
The purpose of this utility model is achieved through the following technical solutions:
A kind of multimedia digital active loundspeakers system, including USB interface, SD card interface, TF card interface, bluetooth module, controller, MP3 decoding device, card reader, display screen, power amplifier, audio-frequency divider, high-frequency horn unit, intermediate frequency loudspeaker unit and Low frequency horn unit, described power amplifier connects audio-frequency divider, and described audio-frequency divider connects high-frequency horn unit, intermediate frequency loudspeaker unit and Low frequency horn unit respectively；Described USB interface, SD card interface, TF card interface communicate to connect with controller respectively, described controller communicates to connect with MP3 decoding device, described MP3 decoder communicates to connect with card reader, described card reader communicates to connect with display screen, described controller also communicates to connect with display screen, and described controller is also associated with bluetooth module.
Described bluetooth module, controller, MP3 decoding device, card reader, display screen, power amplifier, audio-frequency divider, high-frequency horn unit, intermediate frequency loudspeaker unit and Low frequency horn unit can be selected for any prior art and realize.
Utility model works principle is as follows:
Music file can be transferred to controller by either types such as USB interface, SD card interface, TF card interfaces, controller can also be transferred to by bluetooth module, it is then passed through MP3 decoding device the form of music file is decoded, then reads data by card reader, be finally shown on display screen.MP3 decoding device is by the audio signal transmission in music file to power amplifier simultaneously, then separates high-frequency audio, middle frequency domain audio and low frequency audio frequency through audio-frequency divider, is exported respectively by high-frequency horn unit, intermediate frequency loudspeaker unit and Low frequency horn unit the most respectively.This utility model supports the input of multiple music file, simultaneously by frequency dividing output detailed for the audio signal in music file, it is achieved that music file input and the variation of output, improves user's experience to tonequality.
Further, described power amplifier is connected with mobile phone by data wire.
After adopting the structure, can realize the connection of mobile phone and power amplifier, in hands on-line operation, directly can play back after being amplified by power amplifier by the music file in mobile phone, further increase source of sound pattern, the most convenient people use.
Further, also including that power supply and charging circuit, described power supply are connected with charging circuit, described charging circuit is connected with mobile phone by data wire.
After adopting the structure, while mobile phone to play music, it is also possible to mobile phone is charged.
The beneficial effects of the utility model are
:
This utility model supports the input of multiple music file, simultaneously by frequency dividing output detailed for the audio signal in music file, it is achieved that music file input and the variation of output, improves user's experience to tonequality.
