A mask apparatus comprising:

• a mask body provided with a microphone;
• a mask body cover coupled to a front surface of the mask body and having a front opening through which sound is output forward;
• a sealing portion coupled to a rear surface of the mask body and forming a breathing space;
• and
• a first speaker fixed to one of the mask body or the mask body cover and outputting a sound input by the microphone;
• wherein a first resonance space is formed between the mask body and the mask body cover to amplify the sound output from the first speaker and output the sound to the front opening,
• wherein the mask apparatus further comprises:
• a second speaker fixed to one of the mask body or the mask body cover and outputting sound toward a user's ear;
• a wireless communication portion for wireless communication;
• a first boundary region forming a first boundary space in the sealing portion, the first boundary space being disposed inside the breathing space;
• and
• a second boundary region forming a second boundary space in the mask body, the second boundary space being disposed outside the breathing space,
• wherein the microphone is located in the first boundary space,
• wherein the first speaker and the second speaker are located in the second boundary space,
• wherein the first speaker outputs a sound input by the microphone,
• wherein the second speaker outputs a sound received by the wireless communication portion, and
• wherein the second speaker is located higher than the first speaker.
