Technical field

The utility model relates to a kind of active audio amplifier.

Background technology

The music of MP3 digital audio format, take up space less and be convenient to from network advantage such as down loading updating because it has file, be subjected to people's popular welcome, and traditional active audio amplifier can't be play-overed the music of these forms, must use players such as computer or MP3 to read numeral after being converted to audio signal, could play by active audio amplifier, use very inconvenient.In addition,, not only can the minimizing expense pay, can also improve the utilance of active audio amplifier simultaneously if active audio amplifier can have functions such as broadcast receiver, clock and alarm clock, phone automatic-answering back device and message just recorded concurrently simultaneously.

The utility model content

At the deficiencies in the prior art, the purpose of this utility model just provides a kind of having concurrently and play-overs MP3 digital audio format music, broadcast listening, and multi-functional Improved Active Speakers such as phone automatic-answering back device and recording are provided.

For achieving the above object, a kind of Improved Active Speaker of the utility model comprises power amplifier module and loud speaker, also comprises control device, main control module, MP3 decoding circuit module, USB interface, receiver circuit module and phone automatic-answering back device and recording circuit module, wherein

Control device links to each other with main control module, and control device sends operational order to main control module;

Main control module links to each other with MP3 decoding circuit module, USB interface and receiver circuit module respectively, and main control module sends control command according to analysis result to corresponding module after the control command that receives is analyzed;

The MP3 decoding circuit module is according to the instruction of main control module, with after reading file from the MP3 format in the memory device on the USB interface and being converted into simulated audio signal, is delivered to the power amplifier module and passes through loudspeaker plays;

The receiver circuit module is accepted and is carried out from the control command of main control module and the radio signals that receives the outside;

Phone automatic-answering back device and recording circuit module have telephone circuit port, this phone automatic-answering back device circuit module links to each other with described main control module with described loud speaker respectively, and this phone automatic-answering back device of this master control module controls and recording circuit module realize externally replying with the active of incoming call and recording.

Further, described control device has control panel, and this control panel is provided with the control button; Simultaneously, described control device has infrared remote controller, and the receiver of this infrared remote controller is arranged on the described control panel.

Further, described main control module has LCD display, and this LCD display shows content corresponding according to the instruction that shows main control module, and LCD display is installed on the described control panel.

Further, also comprise clock module, this clock module links to each other with main control module, and clock module has independently reserve battery, makes it have timing and calendar function.

Further, described main control module has memory cell, and this memory cell exchanges the required data of various functions according to the instruction storage of main control module, comprises the voice data on the External memory equipment that connects on the described USB interface.

Compared with prior art, the utility model Improved Active Speaker take into account the music of play-overing the MP3 digital audio format, can broadcast listening, provide clock to show and alarm clock calling, and utilize active audio amplifier to make plain old telephone have the function of automatic-answering back device and recording, integration height not only, reduce equipment purchase, and increased the function of active audio amplifier, also improved the utilization rate of active audio amplifier.

Description of drawings

Fig. 1 is the structured flowchart of this Improved Active Speaker.

Embodiment

Below in conjunction with accompanying drawing, the utility model Improved Active Speaker is described in further detail:

As shown in Figure 1, active audio amplifier comprises a control device, main control module, MP3 decoding circuit module, receiver circuit module, phone automatic-answering back device and recording circuit module, power amplifier module, clock module and loud speaker; Control device has control panel, and control panel is provided with control button and infrared remote receiver, and control device links to each other with main control module, and the user sends to main control module by the control button with control command; Main control module links to each other with clock module with MP3 decoding circuit module, receiver circuit module, phone automatic-answering back device and recording circuit module, power amplifier module respectively, main control module sends control command according to analysis result to corresponding module after the control command that receives is analyzed.Main control module also is connected with USB interface and LCD display, and LCD display is arranged on the control panel.
