Technical field
The present invention relates to technology for loudspeaker box field, relate in particular to a kind of WiFi(Wireless Fidelity, a kind of wireless communication technology) wireless sound box.
Background technology
At present, wireless sound box is mostly blue teeth wireless audio amplifier, and it adopts Bluetooth technology based on wireless transmission audio file, still, along with the development of bluetooth 4.0 technology, Bluetooth technology does not still solve the shortcoming that transmission range is near, transmission speed is restricted, distortion is high, quality is low; In addition, blue teeth wireless audio amplifier conventionally can only transfer audio files, but there is no audio decoder function, the audio decoder ability of source equipment is had to certain requirement, and some high-quality harmless music are had no idea to transmit.
Summary of the invention
The object of the invention is to provide for the deficiencies in the prior art a kind of long transmission distance, transmission bandwidth high, can guarantee that audio file transmissions is undistorted, self there is the WiFi wireless sound box of audio decoder function.
To achieve these goals, the invention provides a kind of WiFi wireless sound box, comprise and there is the USB WiFi module that the model that sends data function and receive data function is RT8188CUS, the on-chip system chip that is RTD1034 for the model of high definition audio media file of decoding, for driving the audio power amplifier unit of loudspeaker; Described USB WiFi module is connected with the transceiving data end of described on-chip system chip, and described on-chip system chip is connected with buffer unit and flash cell, and described audio power amplifier unit is connected with the audio signal output end of on-chip system chip.
Preferably, described audio power amplifier unit is audio frequency power amplifier chip, and the model of this audio frequency power amplifier chip is CS42L51.
Preferably, described buffer unit is 256MB DDR3 cache chip.
Preferably, described flash cell is 16MB NOR Flash flash chip.
Beneficial effect of the present invention is:
WiFi wireless sound box of the present invention adopts the USB WiFi module that model is RT8188CUS to transmit and receive data, this USB WiFi module meet ieee standard 802.11b/g/n and speed be 150M, communication distance in spacious region, reach 100 meters, transmission bandwidth high, can guarantee that audio file transmissions is undistorted; And can realize that local audio is play by USB WiFi module, online audio frequency plays, supports the WirelessHD technology based on Wi-Fi802.11n communication protocol that intel WiDi(Intel releases) 3.5, support the application of Miracast(based on Wi-Fi Direct) etc. function; Further, the on-chip system chip that WiFi wireless sound box model of the present invention is RTD1034 is the on-chip system chip of an integrated high definition audio HDAVC/VC-1 decoding, it can be realized the high definition audio media file of multiple format is decoded, make WiFi wireless sound box of the present invention self there is audio decoder function, therefore, audio decoder ability to source equipment does not require, and only needs source equipment to support WiFi to connect.Therefore, WiFi wireless sound box of the present invention have long transmission distance, transmission bandwidth high, can guarantee that audio file transmissions is undistorted, self there is the features such as audio decoder function.
Accompanying drawing explanation
Fig. 1 is frame principle figure of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Please refer to Fig. 1, WiFi wireless sound box of the present invention, comprise and there is the USB WiFi module 1 that the model that sends data function and receive data function is RT8188CUS, on-chip system chip (the English that is RTD1034 for the model of high definition audio media file of decoding, SoC:System on a Chip) 2, for driving the audio power amplifier unit 5 of loudspeaker; USB WiFi module 1 is connected with the transceiving data end of on-chip system chip 2, and on-chip system chip 2 is connected with buffer unit 3 and flash cell 4, and audio power amplifier unit 5 is connected with the audio signal output end of on-chip system chip 2.When work, WiFi wireless sound box of the present invention can carry out wireless connections by USB WiFi module 1 and source equipment equipment such as (as:) mobile phone, panel computer, PC, the high definition audio media file that USB WiFi module 1 receives, after the decoding of on-chip system chip 2, can drive loudspeaker to play music by audio power amplifier unit 5.
Specifically; audio power amplifier unit 5 is audio frequency power amplifier chip; the model of this audio frequency power amplifier chip is CS42L51; certainly, aborning, according to practical application needs; described audio power amplifier unit 5 can be also other chip or circuit; and be not limited only to the audio frequency power amplifier chip of above-mentioned model, as long as it has loudspeaker and drives function, should belong to protection scope of the present invention.
Wherein, buffer unit 3 is 256MB DDR3 cache chip, and flash cell 4 is 16MB NOR Flash flash chip, take the on-chip system chip 2 that model is RTD1034 of arranging in pairs or groups.
Wherein, model is RT8188CUS USB WiFi module 1 is built-in meets the low-power consumption WiFi module of ieee standard 802.11b/g/n150M speed.
The operation principle of WiFi wireless sound box of the present invention:
After the energising of this equipment, model is that the on-chip system chip 2 of RTD1034 is first started working, on-chip system chip 2 reads the program writing in flash cell 4 and carries out, USB WiFi module 1 is opened the outside AP((Wireless of real time scan) Access Point, i.e. (wireless) access points), and broadcast own SSID(Service SetIdentifier, service set) and IP address, wait for the connection of source equipment.After source equipment connection, source equipment is equivalent to a hand-held remote controller (it is connected this equipment access exterior I nternet(internet can be set by WiFi), this arranges just for playing online audio frequency, play local audio not must this arrange), control can wirelessly not break, source equipment sends audio file request, after ID confirms, carry out IEEE802.11b/g/n protocol transmission data, when data traffic is larger, on-chip system chip 2 deposits a part of data in buffer unit 3, due to the model on-chip system chip 2 that is RTD1034 inner integrated high definition audio HD AVC/VC-1 decoder, therefore, 2 pairs of decoding datas of on-chip system chip are communicated by letter with audio power amplifier unit 5 by IIC agreement after processing, (for example: Speakers) drive loudspeaker, export high-quality music.
In sum, wireless sound box of the present invention, the audio cable and the interface that with the wireless mode of WiFi, replace traditional audio amplifier can conveniently be realized mobile phone, panel computer, PC(PC for user neatly on traditional audio amplifier) etc. realize the real-time Transmission of high quality audio media file in terminal.
Finally should be noted that; above embodiment is only in order to illustrate technical scheme of the present invention; but not limiting the scope of the invention; although the present invention has been done to explain with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; technical scheme of the present invention is modified or is equal to replacement, all belong to protection scope of the present invention.
