Abstract

The utility model relates to a radio with digital recording. The radio comprises a reception antenna, a sound-reception module, a power amplification module, a loudspeaker, a button control module and a digital recording module, the digital recording module comprises a preposition circuit, a microprocessor and a TF storage module, the digital recording module is also provided with a recording interface and a pick-up connected with the recording interface, wherein the microprocessor is also connected with the sound-reception module and the power amplification module, and the TF storage module comprises a TF storage card and a TF card slot. According to the radio, broadcasting signals are recorded during usage when sounds are not played, the recorded broadcasting signals do not contain external noises; since broadcasting contents are stored in the TF storage card, the broadcasting contents can be taken out and connected with equipment which can perform digital audio processing such as a computer, an MP3, a card-inserting sound device etc. to play so that the spreading and the listening of broadcasting programs are significantly promoted.

Description

Broadcast receiver with digital recording

Technical field:

The utility model relates to radio devices technical field, refers in particular to a kind of broadcast receiver with digital recording.

Background technology:

Existing broadcast receiver generally only has function of radio receiver, does not possess sound-recording function.Certainly, also there is on the market the multimedia equipment that much integrates radio reception, sound-recording function, for example digital code player, computer, mobile phone etc., but the recording of these equipment generally can only be recorded external environment condition sound, cannot record the broadcast sounds self receiving.While therefore using the said equipment broadcast listening, generally need to could listen at broadcast specific time period, it is large that this wherein just may run into ambient noise, the problems such as audibility is not good, cause the user cannot complete uppick broadcasted content, make them miss some broadcast programs good or that it is liked, to user, make troubles.Even if record with other professional recording devices when listening to, also can be mingled with the noise of environment, recording effect is not good.

Utility model content:

The purpose of this utility model is to overcome weak point on existing radio function, and a kind of broadcast receiver with digital recording is provided.

The technical scheme that the utility model is realized its object employing is: a kind of broadcast receiver with digital recording, comprise reception antenna, radio reception module, power amplifier module, loud speaker and key controlled module, this broadcast receiver also comprises digital recording module, described digital recording module comprises front end circuit, microprocessor, TF memory module, and the pick-up that is provided with recording access and is attached thereto, wherein microprocessor is also connected with power amplifier module with radio reception module; TF memory module is comprised of TF storage card and TF card slot.

Under the utility model broadcast receiver can be recorded broadcast singal in use in the situation that not playing sound, and the broadcast singal of recording can not contain the hum of external environment condition, like this, broadcasted content under record can user when an opportunity arises, do not have noisy time and listen to again, or repeat to listen to; And play owing to being stored in TF storage card, can taking out to receive on the equipment that computer, MP3, plug-in card sounding etc. can carry out digital audio processing, greatly promoted the propagation of broadcast program and listened to.

Accompanying drawing explanation:

Fig. 1 is the wireless structural principle block diagram of the utility model.

Embodiment:

Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.

As shown in Figure 1, broadcast receiver with digital recording described in the utility model comprises and connects a kind of broadcast receiver with digital recording, comprise reception antenna 1, radio reception module 2, power amplifier module 4, loud speaker 5 and key controlled module 6, this broadcast receiver also comprises digital recording module, described digital recording module comprises front end circuit 71, microprocessor 3, TF memory module, and the pick-up 73 that is provided with recording access 72 and is attached thereto, wherein microprocessor 3 is also connected with power amplifier module 4 with radio reception module 2; TF memory module is comprised of TF storage card 81 and TF card slot 82.

Except passing through, reception antenna 1, radio reception module 2, microprocessor 3, power amplifier module 4, loud speaker 5 and key controlled module 6 are normal to be used existing function of radio receiver the utility model, the sound-recording function also with interior record and two kinds of modes of outer record, specific works principle is as follows:

During interior record: close pick-up 73, now, by reception antenna 1, by radio reception module 2 receiving broadcast signals, the processing through front end circuit 71 and microprocessor 3, changes into digital audio and video signals, by the TF storage card 81 of TF memory module, stored; During audio signal in need to playing TF storage card 81, by key controlled system 6, control digital audio and video signals corresponding to microprocessors 3 decoding, then play out recording via power amplifier module 4 and loud speaker 5.

During outer record: open pick-up 73 and can include external voice signal, then the processing by front end circuit 71 and microprocessor 3 converts digital audio and video signals to, is stored in TF storage card 81.In like manner, in the time of need to playing, by key controlled system 6, control the microprocessors corresponding digital audio and video signals of decoding, then play out recording via power amplifier module 4 and loud speaker 5.

Therefore, under the utility model broadcast receiver can be recorded broadcast singal in use in the situation that not playing sound, and the broadcast singal of recording can not contain the hum of external environment condition, like this, broadcasted content under record can user when an opportunity arises, do not have noisy time and listen to again, or repeat to listen to; And play owing to being stored in TF storage card, can taking out to receive on the equipment that computer, MP3, plug-in card sounding etc. can carry out digital audio processing, greatly promoted the propagation of broadcast program and listened to.

In addition, the utility model broadcast receiver also has the function of directly including external environment condition sound concurrently, also can directly make common sound pick-up outfit and use.Simultaneously, microprocessor can also be with the audio signal decoding disposal ability of multiple format, the audio signal decoding that is stored in the forms such as MP3, WMA in TF card, VOX, WAV can be play, thereby make the utility model broadcast receiver also can be used as a digital audio-frequency player.

The above, be only the better case study on implementation of one of the utility model, when not limiting the utility model practical range, allly according to the application's scope, does impartial change and modify, and all should belong in the utility model covering scope.
