Abstract: A sound device including a transducer, a housing accommodating the transducer, the transducer having a front chamber and a back chamber that face each other with respect to the transducer, and a microphone disposed inside the front chamber. The housing includes a speaker hole located at an outer surface of the housing at a portion of the front chamber, an air hole located at the outer surface of the housing at a rear portion of the back chamber, and an inner space configured to allow air passing through the air hole to flow into the front chamber therethrough independent of the back chamber. The transducer outputs sound based on sound information received by the microphone.
