1 is a view illustrating an earphone according to an embodiment.

Referring to FIG. 1, an external perspective view of an earphone 100 according to an embodiment is shown.

As shown in FIG. 1, the earphone 100 is an apparatus mounted on a user's ear, and can transmit sound generated based on an electric signal to a user or convert voice transmitted from a user into an electric signal. For this, the earphone 100 may include a speaker, a microphone, a processor, and the like, and these various components may be surrounded by the housing 110.

The housing 110 can accommodate a speaker, a microphone, a processor, and the like included in the earphone 100 in the inner space of the earphone 100. The housing 110 may have an opening 120 through which the sound generated from the speaker inside the earphone 100 is transmitted to the outside and the voice provided from the outside is transmitted to the internal microphone.

The opening 120 may be a structure that allows the earphone 100 to be secured to the user's ear. The opening 120 may be a part where the sound generated from the speaker inside the earphone 100 is transmitted to the user's ear and the voice of the user provided from the user's ear is transmitted to the microphone inside the earphone 100.

Not only the voice of the user is uttered in the mouth but also part of the voice can be transmitted to the user's ear through the muscles of the skull or face. The opening 120 may allow the user's voice, which is transmitted to the user's ear, to be transmitted to the microphone inside the earphone 100.

2 is a diagram illustrating an internal structure of an earphone according to an embodiment.

Referring to FIG. 2, the earphone 200 includes a speaker 210, a microphone 220, a first radiation hole 230, and a second radiation hole 240.

The speaker 210 outputs sound based on the electric signal. For example, the speaker 210 may output sound based on an electric signal transmitted from a processor included in the earphone 200. The speaker 210 may be disposed adjacent to the microphone 220. The speaker 210 may be located farther away from the opening 250 than the microphone 220.

The microphone 220 may sense the transmitted voice and generate an electrical signal. Here, the microphone 220 can sense not only the user's voice but also various sounds transmitted from the outside, and can generate an electric signal based on the sensed voice, sound, and the like. The microphone 220 may be disposed adjacent to the speaker 210. The microphone 220 may be positioned closer to the opening 250 than the speaker 210.

The first radiation hole 230 may be a structure that allows the sound output from the speaker 210 to be transmitted to the outside (e.g., the user's ear). One end of the first radiation hole 230 may be disposed in the opening 250 and the other end may be connected to the speaker 210.

The second radiation hole 240 may be a structure that allows voice provided from the outside (e.g., the user's ear) to be transmitted to the microphone. One end of the second radiation hole 240 may be disposed in the opening 250 and the other end may be connected to the microphone 220.

The cross-sectional area of the first radiation hole 230 may be greater than or equal to the cross-sectional area of the second radiation hole 240. For example, the diameter of the first radiation hole 230 may be greater than or equal to the diameter of the second radiation hole 240. By designing the diameter of the first radiation hole 230 to be large, it is possible to prevent the high frequency band signal of the sound output from the speaker 210 from being lost while being transmitted through the first radiation hole 230. For example, the ratio between the diameter of the first radiation hole 230 and the second radiation hole 240 may be 5: 5 or preferably 7: 3.

The first radiation hole 230 and the second radiation hole 240 may be arranged to be parallel to each other. The first radiation hole 230 and the second radiation hole 240 may be arranged in the same direction.

The output terminal of the first radiation hole 230 and the input terminal of the second radiation hole 240 may be disposed in the opening 250. Accordingly, the sound output from the speaker 210 through the opening 250 is transmitted to the outside, and the voice provided from the outside can be transmitted to the microphone 220.

The earphone 200 according to one embodiment includes, in addition to the components described above, a processor for controlling the operation of the earphone 200 internal components, a memory including instructions executed by the processor, A battery for providing power to the earphone 200, a communication unit for performing communication with an external device of the earphone 200, and the like. These additional components may be included in the body 260 of the earphone 200 to perform corresponding functions.

The first radiation hole 310 and the second radiation hole 320 shown in FIG. 3 may have different center axes. At this time, the first radiation hole 310 may have a diameter equal to or greater than that of the second radiation hole 320.

The first radiation hole 410 and the second radiation hole 420 shown in FIG. 4 may have the same central axis. In this case, the first radiation hole 410 has a larger diameter than the second radiation hole 420, so that the first radiation hole 410 and the second radiation hole 420 can be physically separated from each other.

The first radiation hole and the second radiation hole shown in FIGS. 3 and 4 are exemplary according to an embodiment. Various structures of the first radiation hole and the second radiation hole, which can be physically separated, Lt; / RTI > In this case, however, the cross-sectional area of the first radiation hole should be greater than or equal to the cross-sectional area of the second radiation hole.
