Abstract

The invention discloses an earphone, which comprises an earphone front shell and an earphone rear shell. Earmuffs are movably sleeved on the outer side of the earphone front shell, and the earmuffs and the earphone front shell can rotate relatively. The front shell of the earphone is provided with an acoustic short-circuit hole along its peripheral edge; the peripheral edge of the inner surface of the earmuffs includes several areas arranged in sequence, and the several areas include an area provided with tuning paper and an area provided with sound baffles And the area that is in direct contact with the outer surface of the earphone front shell. The earphone of the present invention can conveniently adjust the frequency response to different degrees.

Description

technical field [0001] The invention relates to an earphone. Background technique [0002] Headphones are widely used in modern electronic consumer products, such as connecting with digital music equipment to provide sound for individuals. Existing earphones comprise earphone front shell and earphone rear shell, and earphone front shell is provided with earmuff, and earphone rear shell is closed type or semi-closed type, and earmuff adopts airtight leather earmuff sometimes. In the earphone of this structure, the earmuffs are combined with the earphone front shell to form a front acoustic cavity, and the earphone front shell and the earphone rear shell are combined to form a rear acoustic cavity. [0003] In order to adjust the frequency response of the existing earphones, several acoustic short-circuit holes are opened on the front shell of the earphone to meet the needs of adjusting the frequency response. However, different earphone users have different preferences for ...
