Description

This application claims priority to Chinese patent application No. CN202311701969.7, filed on December 11, 2023, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD The present disclosure relates to the field of a sound production apparatus, and in particular, to an ear-clip earphone. BACKGROUND Earphones have been widely used in daily life and can be used in conjunction with electronic devices, such as mobile phones and computers, to provide audio playback for users. Ear-clip earphones, a novel type of earphones, which are typically compact in size and can be clamped onto the wearer's helix, can provide a more comfortable wearing experience. When worn, the sound production portion of the ear-clip earphone is inserted into the wearer's concha cavity, imposing a certain size constraint on the sound production portion and further imposing a certain size constraint on a sound production assembly it can accommodate. Accordingly, the audio performance may be insufficient. SUMMARY Embodiments of the present disclosure provide an ear-clip earphone, comprising a sound production portion, an abutting portion, and an ear hook. The sound production portion is inserted into a concha cavity of a wearer, the abutting portion abuts a rear side of an ear of the wearer, and the ear hook connects the sound production portion and the abutting portion. The abutting portion and the sound production portion are configured to clamp the ear-clip earphone onto a helix of the wearer. The sound production portion includes a first housing and a sound production assembly, the first housing includes a first accommodation cavity, and the sound production assembly is disposed within the first accommodation cavity. The first housing is provided with a sound outlet hole, and sound produced by the sound production assembly is output via the sound outlet hole. The ear hook includes a symmetry plane disposed along a length direction of the ear hook, an angle between a central axis of the sound outlet hole and the symmetry plane is in a range of 15 degrees to 45 degrees, and in a wearing state, the sound outlet hole is located on a lower side of the symmetry plane. In the present disclosure, by setting the angle between the central axis of the sound outlet hole and the symmetry plane in a range of 15 degrees to 45 degrees, the sound outlet hole in the wearing state can be better directed to an ear hole, which is conducive to improving the listening effect of the ear-clip earphone.
