Abstract
A robot includes: a microphone assembly to which a voice is input; an accelerometer connected to a noise source; and a controller configured to control the microphone assembly, wherein the microphone assembly includes: a microphone housing formed in one surface thereof with an opening and formed therein with a space; a microphone accommodated in the space; and an anti-noise speaker accommodated in the space and spaced apart from the microphone, and the controller includes an anti-noise generator configured to output a signal corresponding to an anti-noise against the acquired noise to the anti-noise speaker.
Claims13
A robot comprising:
- a noise source configured to generate a noise;
- a microphone assembly to which a voice is input;
- an accelerometer connected to the noise source;
- and
- a controller configured to control the microphone assembly,
- wherein the microphone assembly includes:
- a microphone housing formed in one surface thereof with an opening and formed therein with a space;
- a microphone accommodated in the space on one wall of the microphone housing;
- and
- an anti-noise speaker accommodated in the space on another wall of the microphone housing while being spaced apart from the microphone, and
- the controller includes an anti-noise generator configured to acquire the noise from the accelerometer and output a signal corresponding to an anti-noise against the acquired noise to the anti-noise speaker,
- wherein the controller includes:
- a printed circuit board (PCB);
- and
- a signal processer installed on the PCB and including the anti-noise generator, and
- wherein the microphone housing, the microphone, and the anti-noise speaker are installed on the PCB.
