Abstract

The invention discloses a semiconductor radio with a memory function. The semiconductor radio comprises a box body and a control circuit inside the box body. The box body is provided with operating buttons used for operating the semiconductor radio. The control circuit includes an input module used for selecting and receiving a high-frequency signal sent by an antenna, a central processing unit used for receiving and processing an uploaded signal of the input module, and an output module used for receiving an output signal of the central processing unit and outputting the signal. The box body is further provided with a main control switch connected with the control circuit and used for controlling on/off of a system, and the main control switch is arranged at the upper end of the box body. By adopting the technical scheme, the semiconductor radio provided by the invention is not only convenient to use, but also can receive signals successfully and work normally in weak-signal areas.

Description

There is the transistor radio of memory function

Technical field

The present invention relates to a kind of semiconductor transmit-receive technology, relate in particular to a kind of transistor radio with memory function.

Background technology

In existing transistor radio, great majority are provided with the antenna that receives external signal on broadcast receiver body, if need to receive external signal, antenna must be extracted out, and aim at the outdoor external signal that just can receive, and work as in the low location of signal, during as high Mountain area, broadcast receiver, owing to not receiving external signal, cannot use.

Summary of the invention

The present invention is directed to the problem that prior art exists, a kind of transistor radio is provided, comprising: box body, and the control circuit of box body inside, on described box body, also there is the action button that operates transistor radio, described control circuit has:

Input module, for the high-frequency signal of selecting and reception antenna spreads out of;

CPU, for receiving and process the signal of uploading of input module;

Output module, for receiving the output signal of CPU, and exports signal.

Described CPU has memory module, and described memory module storage user likes the channel of listening to.

On described box body, have with described control circuit be connected, the total control switch of control system switch, described total control switch is arranged at the upper end of described box body.

Described action button comprises: be arranged on the right side of box body, be used for frequency modulation turntable frequency modulation button and be arranged at the top of described frequency modulation button, control the tuning button of volume.

Described box body has the groove of placing storage battery.

Owing to having adopted technique scheme, the transistor radio with memory function provided by the invention, not only easy to use, and also the channel that can like user produces memory, area a little less than signal also can receive signal smoothly, uses normally broadcast receiver.

Embodiment

For making technical scheme of the present invention and advantage clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is known to complete description:

Transistor radio as depicted in figs. 1 and 2, there is box body 1, the inside of box body 1 has control circuit 2, described vaccum circuit 5 has input module 2.1, CPU 2.2 and output module 2.3, input module 2.1 is used for receiving external signal, and signal is uploaded to CPU 2.2, and CPU 2.2 receives after signal, convert high-frequency signal to middle product signal, after detection and audio frequency amplification, audio signal is passed to output module 2.3.

Described CPU 2.2 has memory module 2.5, if which channel user likes, the memory channel of this channel can being hanked while turning on broadcast receiver, can occur the channel that user likes next time automatically.

As described in Figure 1, the upper end of box body 1 has the total control switch 1.1 that control broadcast receiver starts to close.

As shown in Figure 1, have frequency modulation button 3.1 and audio button 3.2 on the right side of box body 1, frequency modulation button 3.2 is used for regulating frequency, thereby turns the platform of receiving other, and tuning button 3.2 is used for regulating wireless volume problem.

As shown in Figure 1, box body 1 has the groove 1.2 of placing storage battery.

The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
