Description

Open earphone Technical Field The present invention relates to headphones, and more particularly to an open headphone. Background In general, earplugs of in-ear headphones can close the ear canal opening of a user to prevent music from being disturbed by external sounds, but also easily cause uncomfortable wearing feeling such as blocking or closing, and some users choose non-in-ear headphones to avoid the uncomfortable feeling. For example, the non-in-ear earphone is worn and positioned by the ear hook, which is easy to slide or deviate when the user moves vigorously. If the earphone is displaced, the position of the sound outlet and the radial deviation of the sound outlet of the earphone body are easily caused, so that the music with the complete frequency band cannot be smoothly guided into the receiving direction of the original set auditory canal, thereby causing distortion in the performance of sound quality, or the sound outlet quality generates unstable feeling along with shaking. In addition, most of the ear hooks of the non-in-ear earphone are attached to the auricle by taking the upper part of the auricle as a fulcrum and adopting a hanging mode, so that when the attaching area between the skin of a user and the body is small, the user is easy to feel unsafe in psychological sense, and the earphone is worried about falling off or even losing under the condition of no attention. Disclosure of Invention The invention aims at an open earphone which has high positioning stability when worn by a user and good tone quality receiving stability. The open earphone comprises a shell, a loudspeaker, a connecting piece and a supporting piece. The shell is internally provided with a containing space, and the surface of the shell is provided with a sound outlet. The loudspeaker is arranged in the accommodating space to divide the accommodating space into a front cavity and a rear cavity, and the sound outlet hole formed in the shell is in acoustic communication with the front cavity. The connecting piece comprises a first end and a second end which are in opposite states, and the first end of the connecting piece is connected to the surface of the shell. The support piece is connected to the second end of the connecting piece and comprises a bearing part and an acoustic channel. When a user wears the open earphone, the shell is positioned in the concha cavity of the ear of the user, the bearing part of the support piece at least abuts against the lower edge of the concha cavity of the user, the sound outlet hole formed in the shell and the sound outlet channel of the support piece are in acoustic communication with the auditory canal of the user, the sound outlet hole formed in the shell is not contacted with the ear of the user, and the lower edge of the concha cavity is defined as the area below an imaginary line extending towards a horizontal direction from the central position of the opening of the auditory canal of the user. In an embodiment of the invention, the supporting portion has a first side facing away from the housing, and the first side of the supporting portion corresponds to the ear canal opening of the user when the user wears the open earphone, and the ear canal opening is not completely shielded by the sound outlet channel. In an embodiment of the invention, the supporting portion has a second side facing the housing, and the supporting portion surrounds the sound emitting channel, and the sound emitting channel penetrates through the first side and the second side of the supporting portion. In an embodiment of the invention, the sound output by the speaker sequentially passes through the sound outlet hole, the second side of the bearing portion, the first side of the bearing portion and the ear canal opening. In an embodiment of the invention, the width of the opening on the first side of the bearing portion is equal to the width of the opening on the second side of the bearing portion. In an embodiment of the invention, an opening width of the first side of the bearing portion is smaller than an opening width of the second side of the bearing portion. In an embodiment of the invention, the ear protection device further includes an auxiliary positioning member, and the auxiliary positioning member is connected to the housing and configured to be clamped on a portion of the ear of the user. In an embodiment of the present invention, when the user wears the open earphone, the auxiliary positioning element and the auricle contact surface of the user generate a force in a first direction, and the support element and the shell jointly contact the concha cavity of the user to generate a force in a second direction, wherein the first direction is opposite to the second direction. In an embodiment of the invention, the bearing portion is a closed ring. In an embodiment of the invention, the bearing portion is in a non-closed ring shape. In an embodiment of the invention, the bearing portion of th
