Abstract
The utility model provides a digital radio, including antenna, low -noise amplifier, digital radio module, the control unit, broadcast module, the antenna with low -noise amplifier links to each other, low -noise amplifier with digit radio module input links to each other, digit radio module output with the broadcast module links to each other, the control unit respectively with the digit radio module with the broadcast module links to each other. The beneficial effects of the utility model are that: because the place of user when listening to the radio of radio is not quite similar, data signal covers reasons such as the face is little for digital radio is often facing the more weak condition of received signal. The utility model discloses can be in the more weak region of signal, improve the receipt data signal ability of radio greatly, the radio staccato appears a little less than having avoided data signal, can't hear the condition of radio reception even to improve digital radio's the effect of listening to.
Description
Technical field
This utility model relates to electronic technology field, particularly relates to digital radio receiver.
Background technology
Nowadays DAB (DigitalAudioBroadcasting) has been widely applied to vehicle entertainment system, owing to digital signal transmission stands in the distribution difference in the whole world, cause digital radio receiver to be faced with and receive the difficult problem that signal is weak, especially running car is at remote, thickly forested mountains, during the special road sections such as crossing-river tunnel, often cannot uppick digital signal radio.
Utility model content
The technical problem that reception signal is more weak often it is faced with in order to solve digital radio receiver, this utility model provides a kind of digital radio receiver, including antenna, low-noise amplifier, digital radio module, control unit, playing module, described antenna is connected with described low-noise amplifier, described low-noise amplifier is connected with described digital radio module input, described digital radio module outfan is connected with described playing module, and described control unit is connected with described digital radio module and described playing module respectively.
As further improvement of the utility model, described playing module includes power amplifier module and the loudspeaker being connected with described power amplifier module.
As further improvement of the utility model, described low-noise amplifier includes the switch making it open and close.
As further improvement of the utility model, this digital radio receiver also includes that display screen, described display screen are connected with described control unit.
As further improvement of the utility model, described control unit is single-chip microcomputer.
As further improvement of the utility model, this digital radio receiver also includes that memory modules, described single-chip microcomputer are connected with described memory modules.
The beneficial effects of the utility model are: owing to the wireless user place when listening to radio is not quite similar, the reasons such as digital signal coverage rate is little so that digital radio receiver is often faced with and receives the situation that signal is more weak.This utility model can be greatly improved wireless reception digital signal ability in the more weak region of signal, it is to avoid digital signal is weak radio staccato occurs, even can't hear the situation of radio reception, thus improves the audibility of digital radio receiver.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model discloses a kind of digital radio receiver, including antenna 1, low-noise amplifier 2, digital radio module 3, control unit 4, playing module, described antenna 1 is connected with described low-noise amplifier 2, described low-noise amplifier 2 is connected with described digital radio module 3 input, described digital radio module 3 outfan is connected with described playing module, and described control unit 4 is connected with described digital radio module 3 and described playing module respectively.
Described playing module includes power amplifier module 5 and the loudspeaker 6 being connected with described power amplifier module 5.
Described low-noise amplifier 2 includes the switch making it open and close.
This digital radio receiver also includes that display screen, described display screen are connected with described control unit 4.
As preferred embodiment of the present utility model, described control unit 4 is single-chip microcomputer.
This digital radio receiver also includes that memory modules 7, described single-chip microcomputer are connected with described memory modules 7.
This utility model improves the ability receiving digital signal of radio reception by opening low-noise amplifier 2, improves the sensitivity of digital radio receiver, thus improves user's audibility.
Specifically, when the region that running car to signal is more weak, open low-noise amplifier 2, improve audibility, when the region that running car to signal is more weak, close low-noise amplifier 2；Can be manual unlocking or closedown low-noise amplifier 2, can also be to be automatically opened or closed low-noise amplifier 2, i.e. judge that the signal that antenna 1 receives is strong and weak by control unit 4, when the signal is strong, so control unit 4 controls low-noise amplifier 2 and closes, when signal is weak, control unit 4 controls low-noise amplifier 2 and opens.
Owing to the wireless user place when listening to radio is not quite similar, the reasons such as digital signal coverage rate is little so that digital radio receiver is often faced with and receives the situation that signal is more weak.This utility model can be greatly improved wireless reception digital signal ability in the more weak region of signal, it is to avoid digital signal is weak radio staccato occurs, even can't hear the situation of radio reception, thus improves the audibility of digital radio receiver.
The parts such as power supply, circuit board, control knob are also included at digital radio receiver of the present utility model.
Above content is to combine concrete preferred implementation further detailed description of the utility model, it is impossible to assert that of the present utility model being embodied as is confined to these explanations.For this utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, it is also possible to make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
