Description

Technical Field

[0001] The utility model relates to the technical field of earphone tuning, in particular to an earphone tuning structure. Background Art

[0002] Headphones are generally detachable from media players and can be worn in various ways, including in-ear, head-mounted, and earbud styles. They are mostly used in mobile phones, walkmans, radios, portable video games, etc. They are also used in computers and Hi-fi speakers.

[0003] For example, the patent document with application number CN202122443197.4 discloses an earphone tuning structure. The utility model earphone tuning structure can solve the problem that the tuning cloth is easily damaged and noise is easily generated. It includes a shell, a speaker, and a tuning device. The speaker is placed in the shell, and the tuning device is placed at one end of the shell. An earphone wire is arranged at the bottom of the shell, a sound outlet channel is arranged in the shell, and an earplug is arranged at the end of the sound outlet channel. The speaker includes a diaphragm, a tuning cloth, a speaker body, and an extension tube. Bosses are arranged on the top and bottom of the speaker body, a partition is arranged in the shell, the speaker body is a hollow structure, and a plurality of sound outlet holes are arranged at one end of the speaker body. An extension tube is arranged at the other end of the speaker body, and a rear tuning hole is arranged in the extension tube. The rear tuning hole extends into the speaker body to form a front tuning hole. A tuning cloth is arranged between the extension tube and the speaker body, which can effectively prevent dust, water and electricity, increase the service life of the tuning net, reduce noise, and control the tuning plug to change, which is convenient and quick. However, when using this headphone tuning structure, the user often needs to turn the volume adjustment knob to adjust the volume of the headphone. When using the headphone, the user is likely to accidentally touch the volume knob, causing the volume knob to rotate, resulting in a change in the volume, requiring the user to adjust it again, which is inconvenient for the user.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a headphone tuning structure is proposed. Utility Model Content
