Description
Technical field
It the utility model is related to tone frequency channel wire technical field, more particularly to a kind of length-adjustable tone frequency channel wire.
Background technology
Audio connecting cord, abbreviation tone frequency channel wire；For transmitting the line of electroacoustic signal or data.Have for broad sense electric signal with
The major class of optical signal two.The problem of tone frequency channel wire relative video line is more complex, and also one balance is with uneven connection.It is so-called flat
Weighing apparatus connection is exactly that the connection method of a pair of signals balanced, the interference size received due to two signal lines are transmitted with two signal lines
It is identical, opposite in phase, it will finally be cancelled interference.Because the frequency range of audio is relatively low, in the case of the transmission of long range,
Easily it is interfered, therefore, balance connection is as a kind of jamproof connection method, in the audio connection of professional equipment the most
It is common.Also useful two cores shielding line makees audio connecting cord in the connecting line of household electrical appliance, and still, what it was transmitted is left and right sound
Road, it is two signals, is not belonging to balance connection.Uneven connection is exactly that the connection method of signal is only transmitted with a signal line,
Because this connection is easily interfered, so only being used typically on household electrical appliance or in the case that some require relatively low.Tool
The connection of body is by taking XLR joints as an example：1st, connection is balanced：1 pin connects shielding, and 2 pin connect+held (also known as hot junction), and 3 pin connect-are held (also known as
Cold end)；2nd, uneven connection：1 pin and 3 pin are connected shielding, and 2 pin connect+held (signal end).What connection typically basis is selected to set
Depending on the specific requirement of standby docking port, can use balance connection uses balance connection as far as possible, must be referring initially to clear when being attached
Explanation on panel, preferably first read relevant explanation and requirement on operation instructions.It is also possible to run into one end in some occasions
Equipment interface be Balanced interface, the equipment of the other end is the situation of uneven interface, is requiring not bery strict situation, only need
Uneven connection is used, notices that each pin corresponds to can using balance connection, imbalance in balance end.Requiring strict feelings
Condition, just balance must be switched into imbalance using change-over circuit, or imbalance is switched to balance.
But the audio line length that this case has is fixed, when in use and its inconvenient, length is too short, can not connect audio and set
Standby, length is long, then the length that tone frequency channel wire can be caused unnecessary is intertwined, not only storage trouble, and influence it is attractive in appearance, for this I
Design a kind of length-adjustable tone frequency channel wire, to solve the above problems.
