Abstract
A digital electroacoustic transducer apparatus according to the present invention includes: a signal processing circuit that generates a digital processing signal based on a digital signal from a sound source; a first drive unit that receives the digital processing signal; a sound pickup unit that picks up noise and generates a noise signal; a noise canceling circuit that generates a cancel signal based on the noise signal; and a second drive unit that receives the cancel signal, thereby reducing a difference between the phase of the cancel signal and the phase opposite to that of noise.
