Problems solved by technology

During the use of this earphone, the wire runs loosely through the wire hole. When the wire encounters an external force, the wire will move in the wire hole, causing the wire to collide with or scratch the inner wall of the wire hole to generate abnormal sound, thereby Affect the sound effect of headphones
[0003] In addition, when this earphone is in use, external impurities such as debris and sweat can easily enter the sound cavity through the wire hole, which will not only affect the sound output of the earphone, but also cause the internal structure of the earphone, such as the sound unit damage

Abstract

Provided are earphones. Each earphone comprises a casing, a sound generating unit arranged in the casing and a wire connected with the sound generating unit. A sound chamber is arranged in the casing, and the sound generating unit is arranged in the sound chamber. The casing is further provided with a wire hole communicated with the sound chamber, and the wire extends into the sound chamber through the wire hole. The earphone further comprises a fixed cover, the fixed cover and the casing are formed in separation mode, the fixed cover is provided with a fixed hole, the fixed cover is fixed in the wire hole, and the wire is tightened in the fixed hole. The wire in each earphone is tightened in the fixed hole of the fixed cover and can not collide with or scratch the inner wall of the fixed cover to generate abnormal sound so as to ensure sound generating effect of each earphone.

Description

technical field [0001] The invention relates to an earphone, in particular to a wired earphone. Background technique [0002] The earphone usually includes a casing, a sounding unit arranged in the casing, and a wire connecting the sounding unit with an external circuit. The casing is provided with a sound chamber and a wire hole communicating with the sound chamber, the sounding unit is arranged in the sound chamber, and the wire enters the sound chamber through the wire hole to be connected with the sounding unit. In order to make it easier for the wire to enter the sound cavity, the diameter of the wire hole is usually larger than the wire diameter of the wire. During the use of this earphone, the wire runs loosely through the wire hole. When the wire encounters an external force, the wire will move in the wire hole, causing the wire to collide with or scratch the inner wall of the wire hole to generate abnormal sound, thereby Affects the sound output of headphones. ...
