Built-in earplug type noise reduction earmuff

Abstract

The invention provides a built-in earplug type noise reduction earmuff, which relates to the field of technical audio equipment, and solves the technical problem of improving a noise isolation effect. The earmuff comprises an earmuff shell, and an audio noise reduction circuit board and an in-earmuff loudspeaker installed inside the earmuff shell; an audio port of the in-earmuff loudspeaker is connected to an audio output port of the audio noise reduction circuit board; the earmuff is characterized by further comprising an earplug capable of being placed inside the earmuff shell; the earplug is internally provided with an in-earplug loudspeaker; an audio port of the in-earplug loudspeaker is connected to an audio plug through an audio cable, and an outer wall of the earmuff shell is equipped with an audio socket; and the audio socket is connected to the audio output port of the audio noise reduction circuit board. The earmuff provided by the invention can effectively isolate harsh noises.

Description

technical field [0001] The invention relates to audio equipment technology, in particular to a technology of built-in earplug noise reduction earmuffs. Background technique [0002] Earmuffs are usually used to isolate harsh sounds, and traditional earmuffs are usually shells with simple structures, and the noise isolation effect is also poor. Some earmuffs are also equipped with an in-hood speaker in the earmuff shell, through which the audio signal of an external audio device can be played, but only the earmuff shell is responsible for noise isolation, and the noise isolation effect is poor, which will affect the listening sound quality . Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a built-in earplug type noise reduction earmuff with good noise isolation effect. [0004] In order to solve the above-mentioned technical problems, the present invention...
