There is provided an amplifier module which includes a plurality of input terminals; a plurality of amplifier circuits configured to amplify a plurality of input signals which are input from each of the plurality of input terminals and output a plurality of amplified signals; and at least one speaker which is directly connected to at least one output terminals from among the plurality of amplifier circuits, wherein the amplifier module may output the plurality of amplified signals to the at least one speaker based on a number of the at least one speaker.

Amplifier module and control method thereof

A switching amplifier is provided. The switching amplifier includes an input unit which receives an audio signal; a first switching device and a second switching device which switch and output the audio signal; a first snubber circuit which is commonly connected to the first and second switching devices and which reduces overshoot of the audio signal that is output by the first and second switching devices via switching; and a second snubber circuit which is commonly connected to the first and second switching devices, which is connected in parallel to the first snubber circuit and which reduces the overshoot of the audio signal, wherein the first and second snubber circuits alternately reduce the overshoot of the audio signal.

Switching amplifier and audio device

A method of outputting an audio signal includes receiving an audio signal; generating a carrier waves having phases differing from each other; generating modulation signals by comparing the respective carrier waves with the audio signal; amplifying the modulation signals; and outputting the amplified modulation signals.
