GAME USB MICROPHONE WITH DEVICES FOR OUTPUTTING SIGNALS OF TWO SOUND CARDS Russian patent published in 2024 - IPC H04R3/14 

FIELD: acoustics.

SUBSTANCE: game USB microphone with devices for outputting signals of two sound cards contains a main chip, a headphone amplifier chip, microphone capsule and common volume potentiometer, at least 2 sound cards are installed on the main chip, and the main chip is electrically connected to the hybrid potentiometer, which controls output signals of 2 sound cards in equal proportions, such signals then pass through the low-pass filter of the operational amplifier and are amplified for the left and right audio channels by the headphone amplifier chip. Main chip is also electrically connected to a sensor switch designed to switch silent mode of the microphone, and a tactile switch for switching microphone noise suppression. Invention provides that 2 sound cards are installed on the main chip, which are connected to a hybrid potentiometer, using a hybrid potentiometer, the proportion of two output channels is adjusted, thus adjusting the volume ratio of sounds converted from output signals of different sound cards; possibility to select an output device separately in order to realize direct adjustment of the proportion of the background sound of the game and the sound of the voice during the game and chat.

EFFECT: possibility of separate adjustment of sound of game and sound of voice.
