5.1 channel headphone jack

Abstract

The invention provides a 5.1 acoustic channels handset adapter, comprising: an adapter body and a guide blade. Wherein, along the axle of adapter body, a hub whose depth matches the length of handset plug is arranged; several hollowed-out grooves in array are arranged on the upper part of adapter body, while the first block groove group is arranged on the sides of every hollowed-out groove; the at least six guide blades are bended as clamp comprising a elastic contact and a fixed part, wherein, the fixed part is embedded into the block groove and the elastic contact is contained in said hollow-out groove to through the top of axial hub; a earthing terminal is nested on the advancing edge of adapter body, whose elastic contact is on the advancing edge part of adapter body and exposed to advancing edge of said axial hub, and whose fixed part is nested on the groove of adapter body; a end cap covers the advancing edge part of adapter body. The invention has the advantages of simply manufacture and installment while the electrical property of elastic end of said handset plug is stable to attain better 5.1 acoustic channels communication.

Description

1. Technical field [0001] The invention relates to earphones, in particular to a 5.1-channel earphone socket (Phone Jacks) designed to cooperate with multi-channel earphone plugs (Phone Plugs) and used for connecting 5.1-channel earphones. 2. Background technology [0002] The so-called handset plug (Phone Plugs), such as figure 1 The cylindrical terminal 10 shown is used to be inserted into a phone jack (PhoneJacks) 20 for outputting analog audio, and is electrically connected with the guide pieces 21, 22 inside, as figure 2 As shown, the audio is transmitted through the audio wire 14 to the speaker speaker of the terminal, such as a commercially available earphone type. Therefore, the earpiece plug 10 is convenient to operate and use in audio connection. [0003] But the currently commercially available earpiece plug 10 has only a small number of electrodes, so it can only transmit two audio signals at most, namely the left sound channel 11, the right sound channel 12 a...

AI Technical Summary

Problems solved by technology

[0008] However, the aforementioned earphone plug 30 can transmit 5.1 channel signals, but if there is no good earphone jack (Phone Jack) to cooperate with it, then the transmission effect will be reduced

For example, with figure 2 The shown earpiece socket 20 has only two guide plates 21, 22 of different lengths in it, so it cannot be used for the 5.1-channel earphone plug 30; Relatively increasing the number of guide pieces inside the socket 20 involves the configuration of multiple guide pieces inside the entire socket, such as figure 2 In the existing method shown, 6 or 7 guide pieces of different lengths are installed inside an earpiece socket 20, which is not only cumbersome to process, but also requires additional fixing covers or positioning elements, and its spatial arrangement is also difficult; Improper use will affect the transmission of 5.1-channel sound effects

[0009] Therefore, it is the main purpose of the present invention to provide a solution to the problem that the existing earpiece socket cannot be applied to the latest 5.1-channel earphone plug
