Abstract
The invention discloses a high-fidelity wifi stereo, comprising a loudspeaker box, a wifi receiving processor and a power amplifier, wherein the wifi receiving processor comprises a receiving module for receiving a wifi signal and a CPU module for processing data and a control signal, and an output end of the power amplifier is connected with the stereo. The high-fidelity wifi stereo further comprises an independent D/A converter, and an output end of the wifi receiving processor is connected with the independent D/A converter, and an output end of the independent D/A converter is connected with the power amplifier. The high-fidelity wifi stereo of the invention realizes the application of the wifi in the stereo and networking, and is more flexible and convenient for use and wider in audio source by matching with an intelligent mobile terminal, and can be used for simultaneously isolating wifi receiving process and D/A conversion to enable the use of the CPU to be more rational, more efficient and better in effect to achieve high-fidelity effect. The high-fidelity wifi stereo of the invention can be used for processing APE and FLAC of a 24-bit 192 KHz lossless audio file to the highest extent to achieve better HiFi effect.
Description
Technical field
The present invention relates to field of audio, particularly a kind of high-fidelity wifi sound equipment.
Background technology
Music is the important component part of people's spiritual enjoyment, and along with the development of science and technology, the terminal of energy displaying audio file gets more and more, and as mobile phone, computer, MP3 etc., the mode that can obtain audio file also gets more and more.But, the music of high-quality enjoys the impact being subject to audio file itself on the one hand, be subject on the other hand the impact of audio-frequency playing terminal, the broadcasting end that the audio file had is not good or the not good audio file of the broadcasting end had all do not reach the result of broadcast of high-quality yet.Therefore, complete stereo set as people pursue high-quality music enjoy necessaries and increasingly extensive application.But traditional stereo set mostly is wired connection, except connect loaded down with trivial details except, also there is source of sound single, the high request of people's music can not be adapted to.Particularly younger generation Hifi fan, more and more higher to the requirement of stereo set, except play tonequality well except, also require easy to use and flexible.Therefore, wireless technology is subject to the favor of Hifi fan very much in the application of stereo set.Existing wireless acoustics equipment also realizes wireless connecting function substantially, the integrated design of existing wireless audio system multiselect, namely wireless receiving, decoding, conversion, power amplifier set are integrated in loud speaker, although simplified structure like this, but also there is certain deficiency, in the system CPU unit interval, the amount of information of process is limited after all, want it to complete above-mentioned functions simultaneously and be certain to impact effect, particularly when there is digital code information, just be difficult to ensure HiFi effect, namely stereo set well can not ensure hi-fi effect.
Summary of the invention
The present invention is directed to existing wireless acoustics equipment hi-fi effect this deficiency undesirable, a kind of high-fidelity wifi sound equipment is provided.Technical scheme of the present invention is:
A kind of high-fidelity wifi sound equipment, comprise audio amplifier, wifi receiving processor and power amplifier, described wifi receiving processor comprises receiver module for receiving wifi signal and the CPU module for the treatment of data and control signal, described power amplifier output connecting sound equipment, also comprise independent D/A converter, described wifi receiving processor output connects described independent D/A converter, and described independent D/A converter output connects described power amplifier.
The present invention receives the wifi signal from wireless router by receiver module, through the process such as decoding of CPU module, decoded digital audio and video signals forwards independently independent D/A converter to and carries out digital-to-analogue conversion, export simulated audio signal and carry out power amplification to attacking and defending machine, the audio frequency then driving the loud speaker of audio amplifier to carry out high-quality is play.Such information processing can liberate the disposal ability of cpu chip effectively, reduces the load of CPU, not only contributes to receiving the decode of cpu chip audio signal, improve accuracy rate, reduce distortion, the impact on distorted signals such as circuit heating can also be reduced simultaneously, really reach hi-fi effect.
Further, described wifi receiving processor also comprises 24 the 192KHz lossless audio modules supporting APE and FLAC form, and most high energy realizes the process of 24 192KHz lossless audio file APE and FLAC.
Further, described wifi receiving processor is provided with USB interface and uses as satellite interface.
Further, also comprise the memory cell for storing data, described memory cell is connected with described CPU module, and the data of storage can be audio files, also can be control commands.
Further, as preferably, can also arrange the buffer unit for storing audio frequency to be played, described buffer unit is connected with described CPU module.
Further, also comprising can the touch screen module of input control order and display working condition, touch-screen is as man-machine interaction, can input control order to CPU module, shirtsleeve operation and setting are carried out to high-fidelity wifi sound equipment, again can as display unit display working condition or audio-frequency information etc. when not using.
Further, also comprise volume adjusting module, described volume adjusting module is connected with described CPU module, as electrical adjustment module, can reduce the operation regulated analog volume, Loss reducing.
Advantage of the present invention:
(1) the present invention realizes the application of wifi at sound equipment, can realize networking, coordinates intelligent mobile terminal, and use more flexible, audio-source is wider.
(2) wifi receives to process and is separated with D/A conversion by the present invention, and CPU is used more reasonable, efficiency is higher, better effects if, reaches real hi-fi effect.
(3) the most high energy of the present invention realizes the process of 24 192KHz lossless audio file APE and FLAC, can reach fine HiFi effect.
(4) the present invention is scientific and reasonable for structure, and intelligence degree is high, and practicality is good.
