特徴とするヘツドホーン。[Claims for Utility Model Registration] An inner housing formed to enclose an ear cavity, an outer housing formed to enclose the inner housing, and an opposing position in a sealed space between the inner housing and the outer housing. A monitor microphone and a muffling speaker are provided in relation to each other, and the sound picked up by the monitor microphone is used as an input sound, and a cancel sound generation signal is sent to the muffler speaker to generate a cancel sound whose phase is opposite to that of the input sound. A headphone comprising: an external noise canceling circuit that outputs an output; and a receiving speaker that is provided in the inner housing toward the ear cavity, receives a necessary received sound signal from an external device, and outputs the necessary received sound.
