Abstract
The utility model relates to equipment which combines the technology of network audio non-compression transmission remote monitoring, the technology of a digital audio power amplifier and the technology of a high-fidelity professional speaker. The network audio digital active loudspeaker comprises a network audio non-compression transmission remote monitoring module, the digital power amplifier and a high-fidelity speaker unit, wherein the network audio non-compression transmission remote monitoring module receives the digital signal of the network through the technology of the network audio non-compression transmission remote monitoring, converts the digital signal into analog signal and inputs the analog signal to the digital power amplifier, and the analog signal is output by the digital power amplifier to push the speaker unit. The utility model is convenient to use, additionally has the function of a digital audio power amplifier and the high-fidelity professional speaker compared with the existing network audio non-compression transmission remote monitoring equipment, further has a network audio non-compression transmission remote monitoring function and the high-fidelity professional speaker compared with the existing digital power amplifier, and simultaneously has the function of a digital power amplifier and the network audio non-compression transmission remote monitoring function compared with the existing high-fidelity professional speaker.
Description
Technical field
The utility model relates to a kind of network audio does not have compression transmission remote control technology, digital audio frequency power amplifier technology and the high-fidelity specialty audio amplifier technology equipment that combines.
Background technology
Existing network audio does not have compression transmission remote control technology, digital audio frequency power amplifier technology and high-fidelity specialty audio amplifier technology all can only control stereo set separately, and network audio numeral active audio amplifier, network audio is not had compression transmission remote control technology, digital audio frequency power amplifier technology and high-fidelity specialty audio amplifier technology combine together, thereby realize that network audio does not have compression transmission remote control technology, digital audio frequency power amplifier technology and high-fidelity specialty audio amplifier technology in the network audio numeral active audio amplifier of one.
Summary of the invention
The purpose of this utility model is to overcome the weak point that above-mentioned prior art is used separately, provide a kind of network audio not have compression transmission remote control technology, digital audio frequency power amplifier technology and high-fidelity specialty audio amplifier technology in one, network audio numeral active audio amplifier.
To achieve these goals, the utility model adopts following technical scheme:
It comprises that network audio does not have compression transmission remote monitoring module, digital power amplifier and audio amplifier unit, described network audio does not have compression transmission remote monitoring module and the digital signal in the network is not had compression transmission remote control technology by network audio receives and change into analog signal and input to digital power amplifier, promotes the audio amplifier unit by digital power amplifier output then.
Preferably, described audio amplifier unit is the Hi-Fi sound-box unit.
Compared with prior art, the utility model is easy to use, there is not compression transmission remote supervisory and control(ling) equipment than existing network audio, many digital audio frequency power amplifier function and high-fidelity specialty audio amplifiers, do not have compression transmission remote monitoring function and high-fidelity specialty audio amplifier than the existing digital power amplifier equipment network audio of having Duoed, Duo digital power amplifier function and network audio than existing high-fidelity specialty audio amplifier does not have compression and transmits remote monitoring function.Network audio numeral active audio amplifier is a kind of, can not have the Hi-Fi sound-box that the digital power amplifier amplifier function of remote supervisory and control is transmitted in compression by network audio.
Description of drawings
Fig. 1 constitutes block diagram for the utility model.
Embodiment
