The utility model has the positive effects that the power is supplied for the radio through the USB interface of a computer for listening to the broadcasting programs and the radio has small size and convenient and practical use.
Description
Technical field
The utility model relates to a kind of broadcast receiver of USB power supply.
Background technology
Broadcast program can provide various information as traditional media, such as, news, amusement etc., but at present, along with developing rapidly of other medium such as network, TV, mobile phone, broadcast program only can just can go to listen to when driving.And traditional broadcast receiver adopts powered battery, need often to change, and not enough environmental protection, and also volume is more portable.
Summary of the invention
The utility model purpose is in order to overcome the deficiencies in the prior art, and a kind of broadcast receiver of USB power supply is provided, and the USB socket by computer provides power supply for broadcast receiver, light broadcast listening program, and volume is little, and convenient and practical.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of broadcast receiver of USB power supply, comprise housing, USB interface, be arranged on the antenna of described housing side, be arranged on the receiver J-Horner of described housing side, be arranged on the LCD display on the described housing, be arranged on the button on the described housing, be arranged on the power circuit of described enclosure interior, be arranged on the micro controller of described enclosure interior, be arranged on the radio reception circuit of described enclosure interior.
Described power circuit is connected with described USB interface, for described micro controller and radio reception circuit provide power supply.
Described LCD display is connected with described micro controller, is provided with frequency viewing area and volume viewing area.
Described button is connected with described micro controller, comprises that volume increases key, and volume reduces key, and frequency increases key and frequency reduces key.
Described radio reception circuit is connected broadcasting frequency that scalable is listened to and output volume with described micro-control.
Described receiver J-Horner is connected output audio signal with described radio reception circuit.
The beneficial effects of the utility model mainly show: 1, the USB socket by computer provides power supply for broadcast receiver, has avoided the harm of battery to environment; 2, volume is little, and is convenient and practical; 3, have button and liquid crystal interface, the digitlization operation.
Description of drawings
Fig. 1 is the wireless profile schematic diagram of USB power supply;
Fig. 2 is the wireless end view of USB power supply;
Fig. 3 is the wireless schematic block circuit diagram of USB power supply.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1-3, a kind of broadcast receiver of USB power supply, comprise housing 1, USB interface 2 is arranged on the antenna 3 of described housing 1 side, be arranged on the receiver J-Horner 9 of described housing 1 side, be arranged on the LCD display 4 on the described housing 1, be arranged on the button on the described housing 1, be arranged on the power circuit 10 of described housing 1 inside, be arranged on the micro controller 11 of described housing 1 inside, be arranged on the radio reception circuit 12 of described housing 1 inside.
Described housing 1 is a working of plastics, is used to hold electronic circuit and interface unit.Described USB interface 2 links to each other with described housing 1, and the USB socket compatibility with computer can obtain power supply.Described antenna 3 is used to introduce broadcast singal, is arranged on the side of described housing 1, and is scalable, rotatable direction.
Described power circuit 10 is connected with described USB interface 2, and the USB power source conversion is become described micro controller 11 and radio reception circuit 12 operable power supplys.
Described LCD display 4 is connected with described micro controller 11, is provided with frequency viewing area and volume viewing area, can show the broadcasting frequency listened to and the sound size of output.Described button is arranged on the both sides of described LCD display 4, and wherein a side is provided with that frequency increases key 6 and frequency reduces key 5, and opposite side is provided with that volume increases key 8 and volume reduces key 7.Described button is connected with described micro controller 11.
Described radio reception circuit 12 is connected with described micro controller 11.Described micro controller 11 can be set the parameter of described radio reception circuit 12 according to the input of described button, thus the broadcasting frequency that adjusting is listened to and the volume of output.
Described receiver J-Horner 9 is connected with described radio reception circuit 12, is used for output audio signal.Because the restriction of volume can't be provided with the directly loud speaker of output sound, can only listen to by earphone.
In sum, the utility model provides a kind of broadcast receiver of USB power supply, obtain power supply by the USB socket of computer, and volume is little, and is convenient and practical.In using the computer process, can directly this broadcast receiver be inserted on the USB socket, the broadcast listening program, easily convenient again.
