Description

Technical Field

[0001] The present invention relates to the field of earphones, and in particular to an automatically switched ANC noise reduction headphone. Background Art

[0002] At present, headphones are generally divided into on-ear headphones and circumaural headphones according to the size of the earmuffs. Among them, the earmuffs of on-ear headphones are just close to the size of the auricle. When worn, the earmuffs press on the auricle; while the earmuffs of circumaural headphones are larger in size and can wrap the entire ear. Their ability to isolate external noise is better than that of on-ear headphones. The advantage is better noise isolation effect, and because the auricle is completely covered, it is easier to create strong low frequencies. The disadvantage is that they are larger in size, usually heavier, and have poor breathability, especially in the summer when worn. It is easy to feel stuffy.

[0003] In response to the above-mentioned shortcomings of over-ear headphones, open-type headphone structures are currently available on the market. Holes are opened on the headphone shell, and users expose their ears to the air through the holes when wearing them, so as to allow the ears to ventilate and solve the problem of stuffiness after wearing for a long time. However, since the headphone shell is in an open state, external sounds will enter the ears, which can easily affect the noise reduction effect of the headphones. Therefore, in the existing technology, the headphones are set to two forms, namely open form and closed form. When the headphones are in the open form, they can be ventilated and dissipate heat to solve the stuffiness problem. Then, the holes can be covered by a cover / plate, etc., so as to switch the headphones to a sealed state, provide a closed space for the headphones, and ensure the physical noise reduction effect of the headphones. Moreover, an ANC module is basically set inside the headphones. When the headphones are switched to the sealed state, the ANC module can be activated to reduce the noise of the headphones, ensuring the active noise reduction effect of the headphones.

[0004] However, when the headphones are switched to a closed state, the user needs to manually operate to activate the ANC module of the headphones to switch the headphones to active noise reduction mode. Manual operation will reduce the convenience of using the headphones, thereby reducing the user experience.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the Invention

[0006] In view of this, the present invention addresses the deficiencies in the prior art, and its main purpose is to provide a headset with automatic switching ANC noise reduction. The headset is designed to be detachable from the headset body by magnetic attraction through a cover, so that the headset can be used in an open or closed state. The Hall sensor activates the ANC module according to the change of the magnetic field to automatically enter the noise reduction mode of the headset, eliminating the traditional manual control of the headset to enter the noise reduction mode, thereby improving the convenience of using the headset and the user experience.

[0007] To achieve the above object, the present application adopts the following technical solutions: The application discloses an automatic switching ANC noise reduction headset, which comprises two headset bodies, a head beam and a cover. The cover is provided with a first magnetic part, and the headset body is provided with a second magnetic part. The headset body is provided with a Hall sensor and an ANC module.

[0008] The application has obvious advantages and beneficial effects compared with the prior art. Furthermore, the silicone pad is provided to ensure the airtightness of the headset in the closed state. In addition, the adjusting support is provided to adjust the wearing angle of the headset body by rotating the headset body on the adjusting support, thereby improving the user's experience of wearing the headset.
