Headphone with active noise reduction function

Abstract

The invention relates to the technical field of headphones, and discloses a headphone with an active noise reduction function, which comprises a headphone main body, wherein elastic bulges are arranged on the outer wall, in contact with the head of a human body, of the headphone main body when the headphone main body is worn, earmuffs are respectively arranged at two ends of the headphone main body, a control part is arranged on the outer wall of one side of the headphone main body, each earmuff comprises a bottom plate, a protective shell and an inflatable airbag which are connected in sequence, an air pump is arranged in the control part, an inflation inlet is formed in the surface of each inflatable airbag, an inflation tube is arranged between the air pump and each inflation inlet, a deflation opening is formed in the surface of each inflatable airbag, a deflation valve is fixedly installed on each deflation opening, and a microcontroller is arranged on the outer wall of the other side of the headphone main body. According to the headphone with the active noise reduction function, the inflatable airbags and the detachable and replaceable assemblies are arranged, so that the headphone is comfortable to wear and convenient to disassemble and clean, and the problem that dust and sundries are attached and accumulated to affect ear health can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to an earphone with an active noise reduction function. Background technique [0002] Headphones, as the name suggests, are worn on the head, not inserted into the ear canal, and are different from in-ear earplugs. It is composed of two parts, a signal transmitter and an earphone with a signal receiving and amplifying device. The transmitter is connected to the signal source, and it can also be connected to a preamp or headphone amplifier in front of the transmitter to improve the sound quality and adjust the timbre. [0003] In the prior art, headphones mainly include a headband and earmuffs. When in use, the headband is hung on the top of the head, and the earmuffs are attached to the outside of the ears. A cavity is formed between the earmuffs and the ears, and the earmuffs are hung on the headband at the top. It is placed on the top of the user's head and clamped to the side...

AI Technical Summary

Problems solved by technology

[0008] Aiming at the deficiencies of the prior art, the present invention provides a headset with an active noise reduction function, which can solve the problem that the existing headset with an active noise reduction function is fixed on the ear by an elastic member. The ear pressure is high, causing ear discomfort, and there is a filter in the earmuffs to isolate the sound-generating mechanism and the ear canal. The filter is often in direct contact with the ear and is fixedly connected to the earmuffs. It is difficult to disassemble and clean, and dust The accumulation of sundries will not only affect the output sound effect of the earphones, but also cause ear redness, inflammation, and ear health problems; this device effectively solves the problems existing in the prior art by setting a pressure adjustment mechanism and removable components. question
