The first converter is configured to convert an input signal input from a microphone into digital data to generate input digital data. The second converter is configured to convert an internal noise signal into digital data. The signal processing unit is configured to use, as reference data, digital data corresponding to an output signal output to a speaker and digital data having been converted by the second converter, and eliminate a component corresponding to the reference data from the input digital data.
