[0027] See also Figure 1 or Figure 3, which is a schematic diagram of the structure of an earphone 10 according to an embodiment of the present invention. An earphone 10 comprises a housing 100 and a sound unit 200, wherein the housing 100 is used to be embedded in the concha cavity, and the outer wall of the housing 100 is supported against the inner wall of the concha cavity. The shell 100 is provided with a housing cavity 110, and a sound outlet hole 120 is opened on the shell 100, and the sound outlet hole 120 is communicated with the housing cavity 110. The sound unit 200 includes a sound tube 210 and a sound element 220. The sound tube 210 is provided with a mounting cavity 211 and a sound channel 212, and the sound channel 212 is communicated with the mounting cavity 211. The sound tube 210 sequentially penetrates the housing cavity 110 and the sound outlet hole 120, and the portion of the sound tube 210 in the mounting cavity 211 is disposed in the housing cavity 110, and the portion of the sound tube 210 in 212 is exposed outside the sound outlet hole 120. The sound element 220 is disposed in the mounting cavity 211, and the sound outlet surface of the sound element 220 faces the sound channel. The sound tube 210 is installed from the accommodating cavity 110 to the sound outlet 120, and the diameter of the part of the sound tube 210 in the installation cavity 211 is larger than the diameter of the part of the sound tube 210 in the sound channel 212. In this way, the sound tube 210 can be more stably installed in the shell 100, and the sound element 220 is installed in the installation cavity 211. The sound tube 210 can better protect the sound element 220, reduce the probability of damaging the sound element 220 due to the compression of the shell 100, and better protect the sound unit 200. It should be noted that the sound tube 210 is a hard sound tube 210, such as a metal sound tube. The sound outlet surface of the sound element 220 is arranged toward the sound channel, and the sound channel is used to guide and transmit the sound emitted by the sound element 220. The sound element is a speaker. It should be noted that the sound outlet is a sound outlet for mounting a sound unit on the shell, and is not an outlet for sound on the sound transmission path, that is, it is not a real sound outlet.

[0028] In one embodiment, the sound tube is a metal sound tube. It should be noted that by making the sound tube out of metal, the sound transmitted through the metal sound tube can be clearer and have less noise. At the same time, due to the ductility of the metal itself, the wall thickness of the sound tube can be made thinner, thereby reducing the volume of the earphone in the ear of the sound tube, and providing better comfort in use. For another example, the sound tube is provided with a sound receiving ring at the connecting position between the installation cavity and the sound transmission channel. The sound receiving ring extends in a direction away from the installation cavity to form the sound transmission channel. By providing the sound receiving ring, the sound emitted by the sound-emitting element can be gathered and contracted. The sound transmission channel is formed by the sound receiving ring extending in a direction away from the installation cavity, so that the sound transmitted through the sound transmission channel is more profound.

[0029] In order to make the earphone hang on the ear more firmly and reduce the risk of the earphone falling out of the concha cavity, please refer to Figure 1 or Figure 3 The shell 100 is provided with an ear-adhering protrusion 101 on the outside, and the ear-adhering protrusion 101 is used to press against the inner wall of the concha cavity. By providing the ear-adhering protrusion 101, the shell 100 can be more closely attached to the concha cavity of the human ear. For another example, the shell 100 is a flexible shell 100, that is, the ear-adhering protrusion 101 is also a structure of a flexible material. In this way, the flexible material will deform after pressing against the concha cavity. Under the reaction of the deformation force, the shell 100 can be more firmly embedded in the concha cavity, that is, the shell 100 of the earphone can fit the concha cavity more closely.

[0030] In one embodiment, please refer to Figure 1 and Figure 2, the housing 100 is provided with a mounting groove 130, and the mounting groove 130 is communicated with the accommodating cavity 110. For another example, the earphone further comprises a power supply assembly 300, the power supply assembly 300 comprises a bracket 310, a power supply element 320 and an upper cover 330, the power supply element 320 is arranged in the bracket 310, the bracket 310 is mounted on the mounting groove 130, the power supply element 320 is electrically connected to the sound-generating element 220, and the upper cover 330 covers the bracket 310.

For another example, the earphone further includes a holding piece 400, and the holding piece 400 is disposed outside the shell 100. For another example, the holding piece 400 and the shell 100 are an integrally formed structure, so that the structural strength of the holding piece 400 and the shell 100 is higher, and the holding piece 400 facilitates the wearing and taking off of the earphone, that is, a person can wear the earphone on the ear or take it off the ear by holding the holding piece 400.

[0031] In one embodiment, a charging through hole is provided on the shell, the charging through hole is communicated with the mounting groove, and a charging wire passes through the charging through hole and is electrically connected to the power supply element so as to replenish power to the power supply element.

[0032] In another embodiment, see Figure 3 and Figure 4 , the housing 100 is provided with a mounting groove 130, and the mounting groove 130 is communicated with the accommodating cavity 110. For another example, the earphone further includes a face shell 300a and a wire 400a, the face shell 300a is disposed on the mounting groove 130, a through hole (not shown) is disposed in the face shell 300a, and the wire 400a passes through the through hole and is electrically connected to the sound element 220, that is, the earphone described above is a wired earphone.

[0033] In order to make the earphone more comfortable when embedded in the human external auditory canal, the earphone also includes a soft rubber plug, which is placed on the outer wall of the sound tube in the sound transmission channel. The soft rubber plug is used to abut against the inner wall of the external auditory canal when the earphone is embedded in the external auditory canal.
