Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction earphones, in particular to a noise reduction earphone capable of preventing airflow impact. Background Art

[0002] Noise-cancelling headphones refer to headphones that use some method to reduce noise. There are two types of noise-cancelling headphones: active noise-cancelling headphones and passive noise-cancelling headphones. The active noise-cancelling function is to generate an anti-phase sound wave equal to the external noise through the noise reduction system to neutralize the noise, thereby achieving the effect of noise reduction. Passive noise-cancelling headphones mainly form a closed space by surrounding the ears, or use sound insulation materials such as silicone earplugs to block external noise.

[0003] After searching the Chinese patent "Anti-wind Noise Earphones", the publication number is "CN214675591U". This patent blocks the first sound pickup hole by a wind shield to prevent external airflow from directly impacting the microphone, and sets a second sound pickup hole on the wind shield outside the first sound pickup hole. A sound propagation channel is formed between the two to slow down the airflow propagation force, thereby reducing the impact of the airflow on the microphone and improving the anti-wind noise performance of the earphones. However, the noise-canceling earphones have poor resistance to the impact of airflow during exercise and cycling, and it is not convenient to effectively resist and protect the airflow, which reduces the noise reduction effect of the noise-canceling earphones.

[0004] Therefore, a noise reduction headset capable of preventing airflow impact is proposed to solve the above problem. Utility Model Content

[0005] The purpose of the present invention is to provide a noise reduction headset that can prevent airflow impact in order to solve the above problem, thereby improving the problem of inconvenience in effectively resisting and protecting against airflow.

[0007] Preferably, the protective mechanism also includes a support rod fixedly connected to one side of the protective plate, one end of the support rod is fixedly connected to a fixing ring, the outer wall of the cavity is provided with a mounting groove, the fixing ring is clamped with the mounting groove, and one side of the protective plate is provided with a plurality of evenly distributed guide grooves, which can intercept and block the airflow generated when the noise-cancelling headphones are in use, and guide the airflow, thereby reducing the influence of the airflow on the noise-cancelling effect of the noise-cancelling headphones.

[0008] Preferably, a protection pad is fixedly connected to one side of the protective plate.

[0009] Preferably, two clamping blocks are fixedly connected to one side of the fixing ring, and the inner wall of the installation groove is provided with two clamping grooves matching the clamping blocks, so that the protective plate can be installed in a limited position and can also be removed.

[0010] Preferably, a hook is fixedly connected to the top of the cavity to prevent the noise-cancelling earphones from falling during exercise or in windy weather.

[0011] Preferably, the guide assembly includes a mounting block fixedly connected to the bottom end of the earphone body, the outer wall of the mounting block is provided with a plurality of evenly distributed sound pickup holes, the bottom end of the earphone body is fixedly connected to a partition, and the mounting block is arranged on the inner wall of the partition, which can improve the use effect of the noise-cancelling earphones and guide the airflow to reduce the impact of the airflow on the noise-cancelling earphones.

[0012] Preferably, a dustproof net is fixedly connected to one side of the sound pickup hole to prevent dust from entering the sound pickup hole.

[0013] Preferably, the outer wall of the earphone body is provided with a plurality of evenly distributed air guide grooves, and the inner wall of the air guide groove is provided with a sound insulation board, which can guide the wind flow, reduce the impact force of the wind flow on the earphone, and absorb the sound of the wind flow passing through.

[0014] The beneficial effects of the utility model are:

[0015] 1. By setting up a protective mechanism, when the noise-canceling headphones encounter airflow impact, the protective plate can block and intercept the airflow to prevent the airflow from contacting the noise-canceling headphones. The protective plate is in an arc shape, and the protective plate and the guide groove on its surface can guide the windflow, thereby improving the protective plate's guidance of the airflow. The protective plate can be fixedly installed by matching the fixing ring with the mounting groove. The block at one end of the fixing ring matches the slot to further improve the fixing effect of the protective plate. The fixing ring has certain elasticity and toughness. The protective pad on one side of the protective plate contacts the user, which can prevent the airflow from flowing to the noise-canceling headphones from one side, thereby improving the comfort of the noise-canceling headphones, and can protect and intercept the airflow impact force generated when the noise-canceling headphones are used, thereby improving the noise reduction effect of the noise-canceling headphones.

[0016] 2. By setting up a guiding component, when the noise-canceling headphones encounter the impact of airflow, the partition at the bottom of the noise-canceling headphones can disperse the impact force of the airflow and reduce the impact of the airflow on the noise-canceling headphones. The partition is spherical and can come into contact with the airflow to improve the use effect of the microphone. The pickup hole can improve the stability of the microphone. The dustproof net can prevent dust from entering the noise-canceling headphones. The air guide groove can guide the airflow and cooperate with the sound insulation board to reduce the sound generated by the airflow. It can effectively reduce the impact force of the airflow and improve the use effect of the noise-canceling headphones. BRIEF DESCRIPTION OF THE DRAWINGS
