Technical Field

The utility model relates to a technical field of earphone especially indicates a novel english listening comprehension examination earphone.

Background

Must be equipped with the earphone on the english listening examination, generally speaking, current listening comprehension earphone uses comparatively cheap material to make usually, but often unavoidable has a lot of noises in english listening examination, and common sound-proof material also hardly reaches fine syllable-dividing effect, and when listening examination like this, can make the student generally not reach better examination effect.

Disclosure of Invention

The utility model aims at providing a novel english listening comprehension examination earphone, it has the effect of noise control.

The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme:

the utility model provides a novel english listening comprehension examination earphone, includes earphone frame and ear muff, the ear muff border is provided with silica gel sound insulation circle, the ear muff outside is provided with the phonographic recorder, be provided with programmable controller on the phonographic recorder, the controller is connected with the speaker, the speaker is located the ear muff, be provided with the switch on the phonographic recorder.

Preferably, the earmuffs are wrapped with disposable dust covers.

Preferably, the earphone frame comprises a first splicing strip and a second splicing strip, and a splicing structure is arranged between the first splicing strip and the second splicing strip.

Preferably, the splicing structure is provided with a slot on the end face of the first splicing strip and an inserting block on the end face of the second splicing strip, hemispherical convex blocks are arranged on two sides of the inserting block, and grooves matched with the convex blocks are formed in two sides of the slot.

Preferably, the earmuff shell is made of plastic materials, and a cavity layer is arranged inside the earphone shell.

To sum up, the utility model has the advantages that:

the switch is turned on, the programmable controller starts to work, the noise outside the ear muffs is recorded into the sound waves of the reversed noise of the programmable controller in the ear muffs and played through the loudspeaker, so that the noise and the reversed noise sound waves are mutually overlapped, and the active noise reduction effect is achieved.

Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 to 4, a novel english listening comprehension examination earphone, including earphone rack 1 and

ear muff

2, 2 borders of ear muff are provided with silica gel sound insulation circle 21, 2 outsides of ear muff are provided with phonographic recorder 22, be provided with programmable controller 23 on the phonographic recorder 22, the controller is connected with speaker 24, speaker 24 is located ear muff 2, be provided with switch 25 on the phonographic recorder 22.

The working principle is as follows: the switch 25 is turned on, the programmable controller 23 starts to work, the noise outside the ear muffs 2 on the belt is recorded into the sound wave of the reversed noise of the programmable controller 23 in the ear muffs 2 and is played through the loudspeaker 24, so that the noise and the reversed noise sound wave are mutually overlapped, and the active noise reduction effect is achieved.

The disposable dust cover 26 is wrapped outside the ear muffs 2, and the structure can ensure that the ear muffs 2 can be reused, and meanwhile, dust is not accumulated when the ear muffs 2 are not used for a long time.

The earphone frame 1 comprises a first splicing strip 11 and a second splicing strip 12, a splicing structure 13 is arranged between the first splicing strip 11 and the second splicing strip 12, the earphone frame 1 can be made not to need a large accommodating area by adopting the structure, and the earphone frame does not occupy space when not used.

The splicing structure 13 is provided with the inserting blocks 132 arranged on the slot 131 on the end face of the first splicing strip 11 and the end face of the second splicing strip 12, the two sides of each inserting block 132 are provided with the hemispherical bumps 1321, the two sides of each slot 131 are provided with the grooves 1311 of the adaptive bumps 1321, and the splicing structure 13 can be spliced and detached more easily by adopting the structure.

The shell of the ear muff 2 is made of plastic materials, the cavity layer 27 is arranged inside the shell of the ear muff 2, and the structure can enable the earphone shell to be more sound-proof.

The above description is only for the preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention is disclosed in the preferred embodiment, it is not limited to the above description, and any person skilled in the art can make some changes or modifications to equivalent embodiments without departing from the scope of the present invention, but all the technical solutions of the present invention are within the scope of the present invention.
