When the battery 230 is fully charged, the signal light is used to indicate. When the power of the battery 230 is too low, the signal light is used to indicate. Different states can be indicated by setting different colors of the signal light.

[0105] Please also read Figures 8 to 10 The earplug 200 is disposed on one side of the first housing portion 111, and one side of the earplug 200 is recessed to form a groove 21 that can cover the bone conduction vibrator 220 (see Fig.10 ), the groove 21 covers the other part of the bone conduction vibrator 220 exposed from the first accommodating groove 112, the groove 21 includes an in-ear side 22 facing the ear and a connection side 23 facing the bone conduction vibrator 220, the in-ear side 22 contacts the ear, the in-ear side 22 and the connection side 23 contact the bone conduction vibrator 220, and the contact between the in-ear side 22 and the ear can play a role in conducting vibration.

[0106] In one possible implementation, the connection side 23 is connected to the first housing portion 111, and a glue layer is provided at the connection between the connection side 23 and the first housing portion 111 to fix the connection between the connection side 23 and the first housing portion 111, thereby ensuring that the earplug 200 is stably covered on the bone conduction vibrator 220. In addition, in other embodiments, a waterproof rubber pad may be provided at the connection between the connection side 23 and the first housing portion 111 to fix the connection between the connection side 23 and the first housing portion 111 and to prevent water damage.

[0107] In the embodiment of the present application, a positioning protrusion 24 is provided on the side of the earplug 200 facing the ear, and the positioning protrusion 24 is obliquely protruded outward from the outer peripheral side of the earplug 200 .

[0108] Specifically, the positioning protrusion 24 includes a first protrusion 241 connected to the earplug 200 and a second protrusion 242 integrally connected to the first protrusion 241, wherein the second protrusion 242 extends from the outer peripheral side of the first protrusion 241 along the extension direction of the first protrusion 241. The upper and lower ends of the first protrusion 241 are both arc-shaped structures, and the second protrusion 242 is an arc-shaped structure as a whole. One end of the first protrusion 241 extends integrally to the outer peripheral side of the earplug 200 and the peripheral area of ​​the side of the earplug 200 facing the ear. A concave arc section (not shown) is provided on the side of the first protrusion 241 facing the ear; one end of the concave arc section extends to the inside of the side of the earplug 200 facing the ear, and the other end extends to the inside of the side of the second protrusion 242 facing the ear. When the earplug 200 is inserted into the ear, the first protrusion 241 and the second protrusion 242 extend toward the ear, and the width of the positioning protrusion 24 gradually decreases from the first protrusion to the second protrusion 242 .

At the same time, the first protrusion 241 and the second protrusion 242 of the positioning protrusion 24 contact the ear and can also play a role of transmitting vibration, that is, the first protrusion 241 and the second protrusion 242 can simultaneously increase the contact area with the ear, thereby improving the sound transmission effect.

[0110] In one possible implementation, the positioning protrusion 24 is preferably a silicone protrusion made of silicone material. The silicone protrusion is a soft material, which makes it more comfortable to wear and avoids the positioning protrusion causing discomfort to the wearer.

[0111] See also Fig.10 , Fig.10 This is a schematic diagram of the communication connection between a bone conduction headset and an electronic device according to a preferred embodiment of the present application.

[0112] In at least one embodiment of the present application, the electronic device 2 is a mobile phone. In other embodiments, the electronic device 2 may also be a portable device such as a personal computer, a tablet computer, a personal digital assistant (PDA), a game console, an interactive network television (IPTV), a smart wearable device, a navigation device, or a desktop computer, a digital TV, etc.

[0113] The bone conduction earphone 1 is used to convert the audio in the electronic device 2 into mechanical vibrations of different frequencies. When the user uses the bone conduction earphone 1, the earplug 200 and the bone conduction vibrator 220 covered by the earplug 200 are inserted into the ear, that is, the earplug 200 is inserted into the ear together with the bone conduction vibrator 220 exposed from the first receiving groove 112, which can be inserted into the auricle area or the external auditory canal, so as to realize bone conduction in the ear and improve the listening effect.

[0114] In one possible implementation, when the user uses the bone conduction earphone 1, the wireless communication module in the earphone body 20 communicates with the electronic device 2, and the wireless communication module processes the received signal through the circuit on the circuit board 210 to obtain the corresponding audio signal, and then converts the audio signal into mechanical vibrations of different frequencies through the bone conduction vibrator. The earplug 200 is inserted into the ear together with the other part of the bone conduction vibrator 220 exposed from the first accommodating groove 112, and then transmitted through the following conduction pathway: skull-bone labyrinth-inner ear lymph fluid-spiral device-auditory nerve-cerebral cortex auditory center. Specifically, the mechanical vibration is transmitted to the bone labyrinth through the user's skull, and then the inner ear lymph fluid vibrates, and the spiral device completes the sound perception process, and then the auditory nerve generates nerve impulses and presents them to the auditory center. After comprehensive analysis by the cerebral cortex, the user finally "hears" the sound.

[0115] In the embodiment of the present application, the overall waterproof performance of the earphone is improved through the combined design of the glue layer and the waterproof rubber pad, ensuring its normal use during sports such as running and swimming, thereby improving environmental applicability.

[0116] In summary, the design focus of the present application is that it is mainly through the design of the in-ear structure of the earphone, the in-ear structure includes a bone conduction vibrator 220 and an earplug 200 wrapped around the bone conduction vibrator 220, the earplug 200 is wrapped around the bone conduction vibrator 220, and can protect the bone conduction vibrator 220. At the same time, the earplug 200 and the bone conduction vibrator 220 are inserted into the ear together, and the earplug 200 can conduct the vibration of the bone conduction vibrator 220. The earplug 200 cooperates with the bone conduction vibrator 220 in the earphone to achieve a better effect of conducting vibration and improve the listening effect. The earplug 200 is made of soft silicone material, which can effectively ensure the comfort of wearing, and the positioning protrusion 24 on the earplug 200 can strengthen the positioning and fixation of the bone conduction earphone 1, which solves the problem of low sound, unclear hearing and other discomfort caused by loose in-ear wearing, avoids the phenomenon of easy falling off of the earphone, and improves the user experience. Secondly, by setting the first connecting piece on the earphone housing 10, it is possible to replace different ear hooks 30, which is more practical.

As long as they are within the spirit and scope of the present application, appropriate changes and modifications to the above embodiments should fall within the scope of protection claimed in the present application.
