Abstract

The utility model discloses a cable structure for audio transmission, comprising a cable, wherein each of two ends of the cable is provided with a connecting plug respectively; the cable arranged between the two connecting plugs is provided with a circuit board that is used for transmitting audio signals; the circuit board is coated by a circuit casing; and two annular grooves used for winding the cable are arranged on the circuit casing. The cable structure has the advantages that an audio source and an audio player can be connected with each other by the cable; therefore, the related audios in the electronic products such as handsets and the like can be played by sound boxes; the utilization ratio of the sound box can be greatly improved; the application space of the sound box is enlarged; and the transmission efficiency of the audio among the electronic products can be improved, and the fidelity of the audio during the transmission process can be improved.

Description

A kind of cable structure that is used for transmission of audio
Technical field
The utility model relates to a kind of instrument that is used for transmission of audio, relates in particular to a kind of cable structure that is used for transmission of audio.
Background technology
Develop rapidly along with science and technology, the electronic product of living in people is seen everywhere, it is more and more convenient to bring for people's life, the function that also has playing back music such as common mobile phone, but be that mobile phone is generally realized music playback function and hand-free call function by its toy trumpet that carries, because it is all very little that mobile phone carries toy trumpet itself, so volume and speech fidelity are all poor, the effect of music and hand-free call is relatively poor good.
At present, the audio amplifier equipment and technology is very ripe, but existing audio amplifier generally only is used to play the audio frequency of TV, apparatus such as computer, has reduced the utilance of audio amplifier, has limited the purposes of audio amplifier, is difficult to satisfy user's demand.
The utility model content
The technical problems to be solved in the utility model provides a kind of cable structure that is used for transmission of audio, to improve the efficiency of transmission of audio frequency between electronic product, improves the fidelity performance of audio frequency in transmission course.
For solving the problems of the technologies described above, the utility model has adopted a kind of like this cable structure that is used for transmission of audio, it comprises cable, the two ends of cable are respectively arranged with attachment plug, cable between the attachment plug is provided with a circuit board that is used for transmitting audio signal, be coated with a circuit shell on this circuit board, the circuit shell is provided with the bipassage ring connected in star that is used to twine cable.
As further improvement of the utility model, the foregoing circuit plate is provided with microphone module, disposes the microphone through hole suitable with microphone module on the circuit shell.
Further, an end of above-mentioned cable is provided with an attachment plug, and the other end is provided with two attachment plugs.
The utility model has the advantages that: utilize cable that audio-source and audio playing apparatus are linked together, thereby can utilize audio amplifier to play related audio in the electronic product such as mobile phone, improved the utilance of audio amplifier greatly, expanded the application space of audio amplifier, improve the efficiency of transmission of audio frequency between electronic product, improved the fidelity performance of audio frequency in transmission course.
Description of drawings
Fig. 1 is the simplified schematic diagram of cable structure in the utility model.
Embodiment
In conjunction with Fig. 1, the cable structure that is used for transmission of audio comprises cable 1, the two ends of cable 1 are respectively arranged with attachment plug 2, cable between the attachment plug 2 is provided with a circuit board that is used for transmitting audio signal, be coated with a circuit shell 3 on this circuit board, circuit shell 3 is provided with the bipassage ring connected in star 4 that is used to twine cable, cable 1 directly can be wrapped in the annular groove 4, has made things convenient for the user to carry.
As further improvement of the utility model, the foregoing circuit plate is provided with microphone module, dispose the microphone through hole 5 suitable on the circuit shell 3 with microphone module, the user can pass through microphone aperture 5 and microphone module transferring voice, has further expanded application space of the present utility model.
Further, an end of cable 1 is provided with an attachment plug, and the other end is provided with two attachment plugs.Attachment plug mode by different has improved flexibility of the present utility model, has made things convenient for user's operation.
