Abstract

The invention discloses an English listening test earphone capable of reducing environmental noise, which comprises a head sleeve, wherein the head sleeve is composed of a first arc-shaped connecting piece and a second arc-shaped connecting piece; the first arc-shaped connecting piece is provided with an arc-shaped mounting groove therein; the left side of the second arc-shaped connecting piece is fixedly provided with a third arc-shaped connecting piece; the third arc-shaped connecting piece is slidably connected with the arc-shaped mounting groove; an electromagnet is embedded in the upper side of the left end of the third arc-shaped connecting piece; a storage battery is fixed in the arc-shaped mounting groove; a switch is mounted on the outer side of the first arc-shaped connecting piece; the switch is electrically connected with the electromagnet and the storage battery; and a permanent magnet matched with the electromagnet is embedded in the inner top wall of the arc-shaped mounting groove. According to the invention, the adjustment mode is convenient, the earphone can be suitable for users with different head shapes, the ears of the users can be well covered by earmuffs, and the influence of environmental noise on the test of the users is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to an earphone for English hearing tests that reduces environmental noise. Background technique [0002] At present, when conducting English listening tests, testers often need to wear corresponding hearing test earphones, so the sound insulation requirements for earphones are very high, but because each student’s head shape is different, the test earphones need to be adjusted appropriately, but now It is not very convenient to adjust the earphones for the English listening test, and it is easy to cause the earmuffs of the earphones to fail to cover the ears, resulting in poor sound insulation and affecting test scores. Therefore, just propose a kind of English listening test earphone that reduces ambient noise to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide an English listening test earphone that reduces environ...
