Abstract
The utility model discloses a PC sound card-based Morse code telegraphy training machine, which comprises a sound card and a telegraph key, and is characterized in that the sound card is provided with an MIC interface and a Speaker interface; the telegraph key is in serial connection between the MIC interface and the Speaker interface via an audio signal line; and headphones are in parallel connection between the MIC interface and the Speaker interface via an audio signal line. With the PC sound card-based Morse code telegraphy training machine, a telegraph operator can hear whether signals sent by himself are correct or not during the telegraphing process.
Description
Technical field
The utility model relates to a kind of Morse code based on PC sound card training airplane of transmitting messages.
Background technology
Sending box in use, need telegraph operator to be familiar with very much sending accurately the information that needs are expressed to Morse code, therefore each telegraph operator needs the exercise through after a while between life's work, and in exercise process, telegraph operator can not know that whether the information of oneself sending is accurate, can not correct in time mistake, while formally transmitting messages afterwards, the identical mistake of very possible generation, causes sending wrong information.
Utility model content
The utility model is in order to solve current telegraph operator when exercise is transmitted messages, be difficult to check whether accurately problem of the information oneself sent, a kind of Morse code based on PC sound card training airplane of transmitting messages is provided for this reason, comprise sound card and telegraph key, on described sound card, there are MIC interface and Speaker interface, described telegraph key is connected between MIC interface and Speaker interface by audio signal wire, between MIC interface and Speaker interface, by audio signal wire, is also parallel with earphone.
The invention has the beneficial effects as follows:
The present invention is due to the telegraph key of having connected on the MIC interface at sound card and Speaker interface, and earphone in parallel, therefore when exercise telegraph key is sent signal, long signal "-" and pause that earphone can be recognized very brief some signal " ", keep certain hour, and whether the signal that judgement is patted is accurate, if discovery mistake can be corrected in time, avoid occurring identical mistake when formally transmitting messages.
Accompanying drawing explanation
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Disclosed all features in this instructions, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Disclosed arbitrary feature in this instructions, unless narration especially all can be replaced by other equivalences or the alternative features with similar object.That is,, unless narration especially, each feature is an example in a series of equivalences or similar characteristics.
The training airplane of transmitting messages of the Morse code based on PC sound card as shown in Figure 1, comprise sound card and telegraph key, on described sound card, there are MIC interface and Speaker interface, described telegraph key is connected between MIC interface and Speaker interface by audio signal wire, between MIC interface and Speaker interface, by audio signal wire, is also parallel with earphone.The present invention is due to the telegraph key of having connected on the MIC interface at sound card and Speaker interface, and earphone in parallel, therefore when exercise telegraph key is sent signal, long signal "-" and pause that earphone can be recognized very brief some signal " ", keep certain hour, and whether the signal that judgement is patted is accurate, if discovery mistake can be corrected in time, avoid occurring identical mistake when formally transmitting messages.
The utility model is not limited to aforesaid embodiment.The utility model expands to any new feature or any new combination disclosing in this manual, and the arbitrary new method disclosing or step or any new combination of process.
