Detailed Description

The present utility model will be further described with reference to examples and drawings, which are not intended to be limiting, for the understanding of those skilled in the art.

Referring to fig. 1 to 4, the sound pick-up hole physical wind-noise preventing structure for an earphone of the present utility model includes an earphone housing 1, a sound pick-up hole 3, and a sound guiding channel 2 cooperating with the sound pick-up hole 3, wherein the sound guiding channel 2 penetrates through the earphone housing 1, the sound guiding channel 2 is connected with the sound pick-up hole 3, the sound guiding channel 2 is bent from an outer wall of the earphone housing 1 to the sound pick-up hole 3, and an end of the sound guiding channel 2 far away from the outer wall of the earphone housing 1 forms an included angle with the sound pick-up hole 3.

When in actual use, the earphone is worn, the voice of the user is transmitted into the pickup hole 3 of the earphone through the sound guide channel 2, but due to the actual use scene of the earphone, if wind sound enters from the sound guide channel 2 during outdoor use, the conversation quality is not ideal, at this time, an independent chamber is formed between the sound guide channel 2 and the pickup hole 3 because the sound guide channel 2 is bent from the outer wall of the earphone shell 1 to the pickup hole 3, the air flow flows through the independent chamber, and the redundant noise can be filtered by the independent chamber, so that the wind noise generated when the air flow directly enters the pickup hole 3 is reduced, and the conversation quality is improved.

Specifically, the earphone housing 1 has an arc-shaped outer wall 11, and the sound guide channel 2 is arranged on the arc-shaped outer wall 11 of the earphone housing 1 in a penetrating manner, so that the outside air flow can be split to two sides of the earphone housing 1 when the outside air flow flows to the arc-shaped outer wall 11 of the earphone housing 1, and wind noise is reduced for the first time.

Specifically, the sound guiding channel 2 includes a first sound guiding channel 21 and a second sound guiding channel 22, the first sound guiding channel 21 is conducted outside the earphone shell 1, the second sound guiding channel 22 is communicated with the sound pickup hole 3, the first sound guiding channel 21 and the second sound guiding channel 22 are arranged at an included angle, an independent cavity is formed between the second sound guiding channel 22 and the sound pickup hole 3 at the included angle, and noise generated by air flow near the sound pickup hole 3 can be filtered out for the second time by the independent cavity.

Specifically, the end surface of the second sound guiding channel 22 far away from the first sound guiding channel 21 is an arc surface, and the arc design is easier to change the flow direction of external airflow after entering the second sound guiding channel, so that the flow direction of external airflow is changed to flow into the outside of the earphone shell when the external airflow flows to the arc end surface, and the wind noise is further reduced; the second sound guiding channel 22 is arranged at an included angle with the sound pick-up hole 3, and wind noise is reduced for the third time.
