<p>Headphones for removing external noise are disclosed. Each headphone includes a headphone housing, a speaker plate, a microphone, an attenuation circuit, and a speaker. The speaker plate forms a pair of protrusions that are spaced apart from each other at a spacing in which the microphone is placed. The pair of protrusions are further protruded toward the front with respect to the microphone placed in the placement space. Since the headphone has the speaker plate that forms a pair of protrusions protruded from the microphone to the user's ear canal, it has the following advantages. First, although the cover of the headphones is pressed by outer factors, such as the pressure of the user's hand, the headphones can prevent the microphone placed therein from being damaged. Second, due to the reflection characteristics of external noise entered into the headphones, the microphone can collect more external noise, thereby enhancing the external noise collection.</p> |
