TERMINAL DEVICE AND AUDIO PLAYBACK CIRCUIT Russian patent published in 2022 - IPC H04R5/33 

Abstract RU 2771788 C1

FIELD: acoustics.

SUBSTANCE: invention relates to acoustics, in particular, to headphones. The sound reproduction circuit contains two digital-to-analog converters, two stereo headset speakers, an interface and a headset plug, series-connected resistors are connected to the common point of the speakers, the output of the second of which is grounded. The circuit consists of the first and second current routes. The first route is made with the possibility of shunting the current output by the left channel circuit to adjust the voltage supplied to the first end of the right channel of the headset, the second voltage is equal to the voltage at the second end of the right channel of the headset. The second current flow route, made with the possibility of shunting the current output by the right channel circuit to adjust the first voltage supplied back to the first end of the left channel of the headset, when the right channel circuit outputs the audio signal of the right channel, where when the right channel circuit outputs the audio signal of the right channel and the left channel circuit does not output the audio signal of the left channel, the first voltage is equal to the voltage at the second end of the left channel of the headset.

EFFECT: improvement in the separation of signals between the left channel and the right channel.
