Description
Technical field
The utility model relates to a kind of multimedia sound equipment, relates in particular to a kind ofly need not open the multimedia sound equipment that computer just can be listened to network radio station.
Background technology
Along with the development of Internet, the information above the network is more and more, and is not subjected to region, time restriction, as long as no matter where you have your thing that just can find you to want of network, network become people live in an indispensable part;
Procotol (TCP/IP) is international standard, is just to write according to standard to be connected to Internet so all equipments for surfing the net need only the procotol of your software, and follows your scheme, hardware not to have what relation;
Flash disk/SD/MMC is the memory carrier that grows up with IT product in recent years, and volume is little, capacity is big, portable, compatibility is well their biggest advantage, and along with multimedia and development of internet technology, the application meeting of these carriers is more and more universal.
Network radio station is meant and passes through scrambler, the in progress audio or video data-switching in computer the inside is become the form that can directly transmit on Internet, and the user is when signing in to the website in radio station, can download to audio-frequency information, come out by converting audio-frequency information to sound playing again as related softwares such as Realplay or Winamp through coding.Network radio station does not need to take satellite band and frequency resource, and it broadcasts the influence that effect is subjected to the network bandwidth.There is more than 25000 radio station in the whole world now.
The internet radio product that has had at present, function singleness, cost costliness are not suitable for producing in enormous quantities.
Network radio station on the market, radio reception, flash disk/SD/MMC technology separately is all quite ripe, but all is single function at present, does not all have by other approach other functional module to be integrated into.
The utility model content
The utility model corrects at above-mentioned problems, by CPU network, network radio station, radio reception, flash disk/SD/MMC, alarm clock, power amplifier, audio amplifier, Switching Power Supply being combined becomes a multimedia hub that cost performance is high, realizes a tractor serves several purposes, multiple enjoyment.
Concrete technical scheme is: a kind of multimedia sound equipment with network radio station, it comprises power supply, LCDs, audio frequency power amplifier, radio reception module, loudspeaker, audio frequency power amplifier is connected with loudspeaker, it is characterized in that: it also comprises CPU, audio codec, network interface, described radio reception module communicates to connect with CPU and audio codec respectively, and audio codec connects the control audio power amplifier, and audio codec and CPU communicate to connect, LCDs is connected with CPU, and network interface is connected with CPU.It comprises the remote-control transmitting receiver module, and the control transmitting and receiving module is connected with CPU.Described CPU is connected with USB interface.
Description of drawings
Fig. 1 is the circuit working block diagram of the utility model embodiment.
Embodiment
Describe the utility model by the following examples, should be noted that, cited embodiment should not understand the restriction to utility model.
As shown in the figure: the present embodiment master chip is AT91SAM9260; In save as 64MB SDRAM; Storer is 64MB NandFlash, 2MB DataFlash; The wi-fi module adopts RALINKRT3070; 10M/100M ethernet network interface chip adopts the DM9161 of DAVICOM; The radio reception chip adopts the TEA5767HN of Philip; LCD MODULE is FG1288002-FHNN, shows that dot matrix is 128 * 80; It is 2 * 20W that power discharging IC adopts the TDA7265 output power of ST company; It is to write on the Linux2.6.15 that system software is based on kernel.Can be integrated into a system stability, powerful, the reasonable multimedia hub of performance to above-mentioned these parts by software.
The utility model is to be hardware platform with ARM chip AT91SAM9260, carried peripheral hardwares such as USB, SD/MMC, Wi-Fi (802.11b/g), 10M/100M ethernet network interface, LCDs, radio reception module, audio codec, audio frequency power amplifier, loudspeaker, kernel is Linux2.6.15.It is that kernel is write that the application software of complete machine is based on Linux, and this application software is the hinge of total system, and all functions control is all controlled by ARM.Software package mainly contains ICP/IP protocol, wi-fi drives, radio reception drives, and remote control drives, and ADSL, LAN (Local Area Network) Ethernet 10M/100M interface drive, WEP, WPA agreement, DHCP supports PPPoE agreement ADSL, Cable Modem, support the standard telnet mode to be provided with, support self-defined Telnet upgrading to be provided with.Concrete workflow is as follows: at first one when powering on, and ARM can start OS (O:Operating, the S:System that leaves on the FLASH (flash chip); Operating system), the beginning detection hardware, the normal back of hardware starts all peripheral hardwares, machine is started working, enter the network radio station state of acquiescence, machine begins the initialization mixed-media network modules mixed-media, by Wi-Fi or wired connected networks, after net connection is normal, the network radio station that enters last time automatically and listen to before the shutdown; Multimedia player software can be discerned the audio code stream form that receives automatically and decode, D/A (Digital to Analog Converter, the digital to analog converter) converter that decoded digital audio and video signals is sent to audio coding decoding is transformed into simulated audio signal; This simulated audio signal is sent to audio frequency power amplifier and amplifies, and converts power signal to and promotes sound horn; All information indicatings can show by LCDs.When choosing USB or SD/MMC, system arrives RAM (Random AccessMemory: random access memory) with the audio data download that reads, by application software these data processing are become digital audio and video signals, the D/A converter of delivering to audio coding decoding is transformed into simulated audio signal, amplify when this simulated audio signal is sent to audio frequency power amplifier, convert power signal to and promote sound horn.When switching to the FM state, system is by the total line traffic control radio reception of I2C module, receives simulated audio signal behind the FM radio station and is carried out analog to digital converter and is transformed into digital signal, and follow-up processing is the same.After pressing record button, the radio station of listening to can be recorded to USB or SD/MMC, and the audio format of recording is the same with the audio format of listening to the radio station.Simultaneously ARM can be provided with network environment, input by application software and select functions such as (internet radio, FM, USB, SD/MMC circulates switchings), audio signal (comprise regulate volume, high and low tone saves, records).
Obviously; foregoing is just in order to illustrate characteristics of the present utility model; and be not to restriction of the present utility model, the variation that the those of ordinary skill in relevant technologies field is made in the corresponding techniques field according to the utility model should belong to protection category of the present utility model.
