[0003] At present, the more common earphones are divided into in-ear earphones and semi-in-ear earphones. The full in-ear earphone often installs an ear cap to improve the sound insulation effect when the user wears the earphone; the semi-in-ear earphone is relatively more comfortable to wear, but the sound insulation effect is relatively worse.

[0004] Many semi-in-ear earphones on the market also have ear caps, such as a Chinese utility model patent with patent announcement number CN 214707987 U discloses a semi-in-ear ear cap structure and a Bluetooth earphone, which includes a support part and a connecting part, a hollow structure is formed in the support part, an audio outlet and a connecting opening are provided on the support part, the audio outlet and the connecting opening are in communication with the hollow structure, the connecting part is fixed in the hollow structure, and the connecting part is used to connect with the earphone front mouth.

It can avoid causing pain to the ear canal.

[0005] However, the existing dustproof silica gel ear cap still has the following disadvantages:

[0006] In the technical scheme, simply speaking, a semi-in-ear ear cap structure is connected to the in-ear earphone body to avoid causing pain to the ear canal, but because the shape of the support structure in the semi-in-ear ear cap structure is an inwardly converging arc surface, and because the shapes of human ear parts are different, such shape is often difficult to fit when worn, difficult to fit the ear canal, and easy to loosen and leak sound due to accidental touch, and the use experience needs to be improved.

[0007] Therefore, the present inventors propose the following technical scheme. UTILITY MODEL CONTENT
