Description
Technical field
The utility model relates to a kind of broadcast receiver, specifically a kind ofly both can be used for transmitting the sound radio program, can receive more than 10000 radio station all over the world and can put into different categories, again can data services, the internet radio of static and live image etc.
Background technology
The world today, daily life has been enriched in the fast development of various electronic technology and the Internet greatly.The Internet flourish, especially world wide web except traditional mail transfer service is provided, also provide services miscellaneous such as voice, picture and dynamic image.
Also be provided with many radio station on the network at present, these radio station can provide the instant broadcasting or the broadcast of news voice program, and the broadcasting of perhaps playing, news or the program that records bring great convenience to people.Listen to these radio station, generally surf the Net by computer and listen to, yet volume is bigger comparatively speaking owing to computer, and is limited by network line, people just can listen to when having only at home usually.Perhaps use notebook computer to carry out wireless listening to, but still comparatively bother.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of internet radio that can receive the program of radio station on the network.
In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:
A kind of internet radio, comprise the antenna that is loaded on the microprocessor in the broadcast receiver housing and is connected, also comprise the Ethernet treatment circuit, power supply module, audio amplifier circuit, digital audio output module, the display circuit that are connected with microprocessor by circuit, reach key-press module with this microprocessor.
Also comprise the infrared remote control receiver that is connected with microprocessor by circuit.
Described digital audio output module is provided with optical fiber output interface and coaxial output interface.
Described power supply module comprises the power board that is connected with extraneous AC power, the output of this power board is connected with No. two voltage stabilizing circuits with a voltage stabilizing circuit successively, No. one voltage stabilizing circuit is connected with microprocessor respectively with No. two voltage stabilizing circuits, and the output of power board also is connected with audio amplifier circuit.
The radio reception function that the utility model discloses is connected with network, and then listen to program of radio station on the network, can effectively play out audio content by the audio amplifier circuit external loudspeaker, also can associated video be played back by the external display of display circuit, easy to use.In addition, the transmission system good in anti-interference performance of internet radio, noise and distortion in can the erasure signal transmission course, and also the mistake that occurs in the transmission also can be corrected, and can directly provide CD stereo quality.Needed transmitting power is less, helps energy savings and reduces electromagnetic pollution, improves environmental protection.Fixing received signal again can the limit moves edge joint and collects mail number, and is easy to carry, uses flexibly.
