Abstract

The invention provides a circuit for realizing two-way sound transmission on the same port. The circuit comprises a sampling circuit and a switching circuit, wherein the sampling circuit is used for acquiring an input signal of a two-way transmission port; and the switching circuit inputs the difference value of the signal which is acquired by the sampling circuit to a main control chip which can realize judgment and control functions, receives a control signal of the main control chip and realizes the switching between input and output channels according to the control signal; and the switching circuit is connected with the two-way transmission port. The circuit for realizing the two-way sound transmission on the same port realizes the two-way transmission of sound on the two-way transmission port, so the arrangement space of the port is saved, the misplug caused by too many ports is reduced and the use of a user is convenient.

Description

technical field [0001] The invention relates to the field of audio technology, in particular to a circuit for realizing two-way sound transmission on the same port. Background technique [0002] There is a PC sound input port for connecting with the PC, i.e. PC_Audio_in port, on the TV set, and there is also a headphone sound output port for connecting with the earphone. The sound input port of the PC and the sound output port of the earphone are independent of each other, and one-way transmission occupies a large space in the port layout. Moreover, the exposed jacks of these two ports on the TV are very similar, and it is easy for users to insert them by mistake. Contents of the invention [0003] For this reason, the technical problem to be solved by the present invention is: provide a kind of circuit that realizes two-way sound transmission on the same port, make through this port, realize the two-way transmission of sound, save port layout space, reduce the error caus...
