Description

Technical Field

[0001] The utility model belongs to the field of earphone microphones, and particularly relates to a wind-proof structure. Background Art

[0002] A microphone is an energy conversion device that converts sound signals into electrical signals through a built-in sound transmission element.

[0003] When the microphone is used in an outdoor environment, the outdoor wind will form air turbulence near the microphone and generate wind noise. Wind noise will seriously affect the clarity and recognition of the sound. At the same time, wind noise contains a lot of sub-bass components and has high energy, which can easily cause microphone overload distortion. Therefore, wind noise is a source of environmental noise for the microphone, which reduces the performance of picking up sound signals at the microphone and makes the sound signals difficult to understand. Utility Model Content

[0004] In order to solve the above problems, the utility model aims to provide a wind noise protection structure for an earphone microphone, which can effectively suppress the influence of wind noise on the microphone, so that the microphone has better performance in picking up sound signals.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A headphone microphone wind noise protection structure includes a structural body and a microphone, and is characterized in that a first channel and a second channel are arranged in the structural body, two ends of the first channel respectively penetrate the structural body to form an air inlet and an air outlet, one end of the second channel is connected to the first channel, and the microphone is fixedly arranged in the structural body, and the microphone corresponds to the other end of the second channel.

[0007] In the wind noise protection structure, external airflow enters from the air inlet of the first channel, part of it enters the second channel and flows into the microphone, and the other part leaks out from the air outlet of the first channel. The design of the first pipe greatly reduces the air flow, and also avoids the airflow from blowing directly into the microphone receiving hole through the second channel; that is, the design of the wind noise protection structure can effectively suppress the influence of wind noise on the microphone, so that the microphone has better performance in picking up sound signals.

[0008] Furthermore, the first channel is a "U"-shaped channel. The design of the first channel being a "U"-shaped channel makes the first channel more effective in guiding the external airflow.

[0009] Furthermore, the second channel is connected to the middle of the first channel. This design can more effectively prevent the external airflow from blowing directly through the second channel to the microphone sound receiving hole.

[0010] Furthermore, the second channel is a gradual pipe, and the diameter of the second channel increases from one end close to the first channel to the other end close to the microphone.

[0011] Furthermore, a dustproof and sound-permeable mesh is provided at the junction of the first channel and the second channel.

[0012] Furthermore, a sound-transmitting sponge is arranged at the other end of the second channel, and the sound-transmitting sponge is arranged on the microphone. The sound-transmitting sponge can effectively suppress the turbulence of the airflow at the sound receiving hole of the microphone, and further suppress the influence of wind noise on the microphone.

[0013] Furthermore, the structural body includes a first body, a second body, and a third body. The first body, the second body, and the third body are fixed in sequence from top to bottom. The first channel is arranged on the first body, the second channel is arranged on the second body, and the microphone is fixedly arranged on the third body.

[0014] Furthermore, the first body and the third body are made of hard materials, and the second body is made of soft materials.

[0015] Furthermore, the first body and the third body are made of plastic material, and the second body is made of rubber material.

[0016] The beneficial effect of the utility model lies in that, in the wind noise protection structure, external airflow enters from the air inlet of the first channel, a part of it enters the second channel and flows into the microphone, and the other part leaks out from the air outlet of the first channel. The design of the first pipe greatly reduces the air flow, and also avoids the airflow directly blowing the microphone receiving hole through the second channel; that is, the design of the wind noise protection structure can effectively suppress the influence of wind noise on the microphone, so that the microphone has better performance in picking up sound signals.
