[0042] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0043] In the description of the present application, it should be noted that unless specifically defined and limited, the terms "mount", "connect", "connection" should be understood in a broad sense, for example, it can be fixedly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0044] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0045] The terms "first", "second", "third" (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0046] Moreover, the terms "comprising" and "having" and any variations thereof are intended to cover a non-exclusive inclusion, for example, a process, method, system, product or article of manufacture not necessarily limited to those elements specifically listed, but can include other steps or elements not expressly listed or inherent to such process, method, product, or article of manufacture.

[0047] Bone conduction is a way of sound conduction, that is, to convert sound into mechanical vibration of different frequencies, through the skull, bone labyrinth, endolymph, spiral organ, auditory center to transmit sound waves.

[0048] The bone conduction earphone includes a bone conduction speaker, which converts an electrical signal into a sound wave and directly transmits it to the auditory nerve through the bone. Since the step of transmitting the sound wave in the air is omitted, the wearer can clearly hear the sound emitted by the bone conduction speaker even in a noisy environment.

[0049] The bone conduction earphone also includes a receiving microphone, a noise reduction microphone, and a controller. The receiving microphone and the noise reduction microphone are electrically connected to the controller. The receiving microphone is used to collect the sound emitted by the wearer, and the noise reduction microphone is used to collect the ambient sound. The receiving microphone transmits the human voice to the controller, and the noise reduction microphone transmits the ambient sound to the controller. The controller processes the ambient sound through a preset algorithm and only transmits the human voice to the party receiving the sound, achieving the effect of noise reduction.

[0050] In the related art, the receiving microphone and the noise reduction microphone are air conduction microphones. In a high-noise environment, the receiving microphone will also collect noise, making it difficult for the controller to separate and process the ambient sound. After separating and processing the ambient sound, the human voice will also become very small. In a low-noise environment, the noise reduction microphone will also collect human voice, and the controller will also subtract part of the human voice collected by the noise reduction microphone during noise reduction processing, so that the human voice will also become very small. As a result, the sound collection effect of the bone conduction earphone in a high-noise environment and a low-noise environment is poor.

[0051] Based on this, the present application provides a bone conduction earphone, which has good sound collection effect in a high-noise environment and a low-noise environment.

[0053] ReferenceFigures 1 to 4 As shown, the bone conduction earphone 100 provided by the application includes an earphone body 110, an ear hook 120, a bone conduction microphone assembly 130, an air conduction microphone 140, and a controller 150. The bone conduction microphone assembly 130 includes a first bone conduction microphone 131 and a second bone conduction microphone 132. The ear hook 120 is connected to the earphone body 110. The first bone conduction microphone 131 and the air conduction microphone 140 are both connected to the ear hook 120. The first bone conduction microphone 131 is used to fit the cheekbone area 210 of the wearer 200. The air conduction microphone 140 is used to be arranged close to the mouth 220 of the wearer 200. The second bone conduction microphone 132 is arranged on the earphone body 110, and has a gap between the second bone conduction microphone 132 and the back of the neck 230 of the wearer 200. The first bone conduction microphone 131, the second bone conduction microphone 132, and the air conduction microphone 140 are all electrically connected to the controller 150.

[0054] When the sound is higher than the set value, the controller 150 controls the bone conduction microphone assembly 130 to start. The first bone conduction microphone 131 is used to collect the voice of the wearer 200 and convert the voice into a first signal to transmit to the controller 150. The second bone conduction microphone 132 is used to collect the ambient sound and convert the ambient sound into a second signal to transmit to the controller 150. The controller 150 is used to shield the second signal and to transmit the first signal.

[0055] When the sound is lower than the set value, the controller 150 controls the air conduction microphone 140 to start. The air conduction microphone 140 is used to collect the voice of the wearer and convert the voice into a third signal to transmit to the controller 150. The controller 150 is used to transmit the third signal.

[0056] First, the wearing method of the bone conduction earphone 100 provided by the embodiment of the application is described.

[0057] Please continue to participate Figures 1 to 3 As shown, the earphone body 110 is in a structure similar to a U shape. The ear hook 120 is connected to both ends of the earphone body 110. When the wearer 200 wears the bone conduction earphone 100, the ear hook 120 is hung on the ear 240 of the wearer 200, and the earphone body 110 is wrapped around the back of the neck 230 of the wearer 200.

[0058] Next, the setting method of the bone conduction microphone assembly 130 is described.

[0059] The bone conduction microphone assembly 130 includes the first bone conduction microphone 131 and the second bone conduction microphone 132. The first bone conduction microphone 131 and the second bone conduction microphone 132 are both electrically connected to the controller 150.

[0060] The vibration sensor in the first bone conduction microphone 131 receives the vibration of the sound source and converts the vibration of the sound source into an electrical signal. When the wearer 200 speaks, the zygomatic region 210, the mandible or the lower jaw will vibrate with the opening and closing of the mouth 220. The first bone conduction microphone 131 can be attached to one of the zygomatic region 210, the maxilla or the lower jaw, and the vibration sensor in the first bone conduction microphone 131 converts the vibration of the zygomatic region 210, the maxilla or the lower jaw into an electrical signal.

[0061] However, the amplitude of the movement of the maxilla and the mandible is large, and it is not convenient to install a bone conduction microphone at the maxilla and the mandible. Therefore, in the present embodiment, the first bone conduction microphone 131 is attached to the zygomatic region 210 of the wearer 200. When the wearer 200 speaks, the vibration sensor in the first bone conduction microphone 131 can detect the vibration of the zygomatic bone generated when the wearer 200 speaks, and convert the vibration of the zygomatic bone into a first signal and transmit it to the controller 150.

[0062] Next, the arrangement of the second bone conduction microphone 132 will be described.

[0063] The vibration sensor in the second bone conduction microphone 132 is used to convert the vibration of the ambient sound into a second signal and transmit it to the controller 150.

[0064] In order to avoid the vibration generated when the wearer 200 speaks from being transmitted to the vibration sensor in the second bone conduction microphone 132, the second bone conduction microphone 132 needs to be arranged away from the zygomatic region 210 of the wearer 200, and also needs to have a gap between the head of the wearer 200.

[0065] In the present embodiment, the earphone body 110 is wrapped around the back of the neck 230 of the wearer 200, and the earphone body 110 is separated from the first bone conduction microphone 131 by the ear hook 120, so that the second bone conduction microphone 132 is connected to the earphone body 110, so that the second bone conduction microphone 132 is close to the back of the neck 230 of the wearer 200, so that the second bone conduction microphone 132 can be arranged away from the zygomatic region 210 of the wearer 200.

[0066] The gap between the second bone conduction microphone 132 and the back of the neck 230 of the wearer 200 can be achieved in the following two ways.

[0067] In some possible implementation manners, the earphone body 110 can be provided with a connecting rod extending away from the back neck 230 of the wearer 200, and the second bone conduction microphone 132 is mounted on the connecting rod. The second bone conduction microphone 132 is connected to the earphone body 110 through the connecting rod, and the connecting rod can provide a gap between the second bone conduction microphone 132 and the back neck 230 of the wearer 200. In this way, the vibration generated by the wearer 200 when speaking can be prevented from being transmitted to the vibration sensor in the second bone conduction microphone 132. However, the connecting rod provided on the earphone body 110 can affect the overall appearance of the bone conduction earphone 100.

[0068] In another possible implementation manner, the earphone body 110 has a contour consistent with that of the back neck 230 of the wearer 200, and a gap is provided between the earphone body 110 and the back neck 230 of the wearer 200. The earphone body 110 is provided with a first mounting portion 111, and the second bone conduction microphone 132 is arranged on a side of the first mounting portion 111 away from the back neck 230 of the wearer 200.

[0069] Please continue to see Figure 3 As shown in FIG. 1, the earphone body 110 and the back neck 230 of the wearer 200 are concentric arcs, and the diameter of the earphone body 110 is slightly larger than that of the back neck 230 of the wearer 200. In this way, a gap is provided between the earphone body 110 and the back neck 230 of the wearer 200, so that the second bone conduction microphone 132 arranged on the first mounting portion 111 of the earphone body 110 has a gap with the back neck 230 of the wearer 200.

[0070] In order to facilitate the second bone conduction microphone 132 to collect ambient sound, the second bone conduction microphone 132 needs to be arranged away from the back neck 230 of the wearer 200. In this embodiment, the second bone conduction microphone 132 is arranged on a side of the first mounting portion 111 away from the back neck 230 of the wearer 200.

[0071] It should be noted that the earphone body 110 can be provided in a telescopic structure. By adjusting the telescopic structure in the earphone body 110, the back neck 230 of the wearer 200 can have a gap with the earphone body 110 when the bone conduction earphone 100 is worn by different wearers 200.

[0072] Next, the arrangement of the air conduction microphone 140 will be described.

[0073] Figure 5 FIG. 4 is a schematic view of the internal structure of the air conduction microphone 140.

[0074] Please continue to see Figure 5As shown, the air conduction microphone 140 includes a diaphragm 141, a metal plate 142 and a field effect tube 143, the diaphragm 141 is charged, the diaphragm 141 and the metal plate 142 form an air capacitor 144, and the field effect tube 143 is electrically connected with the air capacitor 144.

[0075] When the wearer 200 occurs, the sound wave of the wearer 200 is transmitted to the diaphragm 141, the diaphragm 141 vibrates with the change of the sound wave, so that the capacity of the air capacitor 144 changes, and then the voltage changes, forming an electric signal, and the field effect tube 143 transmits the electric signal after amplification processing.

[0076] The sensor in the air conduction microphone 140 is a capacitive sensor, therefore, the air conduction microphone 140 is more sensitive, in addition, the air conduction microphone 140 directly transmits the sound wave, compared with the bone conduction microphone which transmits the sound through the vibration of the bone, the air conduction microphone 140 has a higher sound restoration degree than the bone conduction microphone.

[0077] The bone conduction earphone 100 provided by the embodiment of the present application utilizes the different characteristics of the bone conduction microphone and the air conduction microphone, uses the bone conduction microphone assembly 130 to receive sound in a high-noise environment, and uses the air conduction microphone 140 to receive sound in a low-noise environment, so that the bone conduction earphone 100 has a good sound receiving effect in both high-noise and low-noise environments.

[0078] Next, the working process of the bone conduction microphone assembly 130, the air conduction microphone 140 and the controller 150 is described.

[0079] In the embodiment, the initial setting of the bone conduction earphone 100 is, for example, that the air conduction microphone 140 works, and the air conduction microphone 140 can also detect the decibel value of the sound, and the controller 150 is provided with a sound setting value, which can be, for example, 70db-80db.

[0080] Specifically, in a high-noise use environment, when the air conduction microphone 140 detects that the sound is higher than the setting value, the controller 150 controls the bone conduction microphone assembly 130 to start working. The working process of the bone conduction microphone assembly 130 is as follows:

[0081] The first bone conduction microphone 131 is attached to the zygomatic region 210 of the wearer 200. Therefore, when the wearer 200 speaks, the vibration sensor in the first bone conduction microphone 131 can sensitively detect the vibration of the zygomatic region generated when the wearer 200 speaks, and convert the vibration of the zygomatic region into a first signal and send it to the controller 150. It should be noted that when the vibration generated by the ambient sound is transmitted to the first bone conduction microphone 131, due to the transmission attenuation of the air medium, the amplitude of the vibration is much smaller than the amplitude of the vibration generated by the zygomatic region 210, so at the source of the sound collected, by attaching the first bone conduction microphone 131 that collects the sound of the wearer 200 to the zygomatic region 210 of the wearer 200, the ambient sound collected by the first bone conduction microphone 131 is much smaller than the human voice. The sound collected by the first bone conduction microphone 131 is converted into a first signal mainly generated by the human voice.

[0082] The second bone conduction microphone 132 is arranged away from the first bone conduction microphone 131 and has a gap between the wearer 200, so that the vibration sensor in the second bone conduction microphone 132 is difficult to detect the vibration of the zygomatic region of the wearer 200, so at the source of the sound collected, the human voice collected by the second bone conduction microphone 132 is much smaller than the ambient sound, and the sound collected by the second bone conduction microphone 132 is converted into a second signal mainly generated by the ambient sound.

[0083] Since the first signal is mainly generated by the human voice and the second signal is mainly generated by the ambient sound, the controller 150 only generates a fourth signal opposite to the second signal according to the second signal, and offsets the second signal, so as to realize the shielding of the second signal, and the influence on the first signal generated by the human voice is small, so that the bone conduction microphone assembly 130 has good noise reduction effect, so that the bone conduction earphone 100 has good sound collecting effect in a high noise environment.

[0084] The bone conduction microphone assembly 130 can also detect the decibel value of the sound.

[0085] In a low noise use environment, when the bone conduction microphone assembly 130 detects that the sound is higher than the set value, the controller 150 controls the air conduction microphone 140 to start working. The working process of the air conduction microphone 140 is as follows:

[0086] The air conduction microphone 140 is arranged close to the mouth 220 of the wearer 200, so that the air capacitor 144 in the air conduction microphone 140 can collect the voice of the wearer 200 in time and accurately. Since the ambient noise is small, when the sound wave formed by the ambient sound is transmitted to the air conduction microphone 140, the vibration amplitude of the sound wave is much smaller than that of the sound wave generated by the voice of the wearer 200 due to the transmission attenuation of the air medium. Therefore, the sound collected by the air conduction microphone 140 is mainly the signal generated by the voice, and without the need for noise reduction processing, the bone conduction earphone 100 has good sound collecting effect in a low noise environment.

[0087] It should be noted that in some embodiments, the controller 150 is further provided with a set time, which can be 10s-20s for example. When the air conduction microphone 140 detects that the sound is higher than the set value for more than the set time, the controller 150 controls the bone conduction microphone assembly 130 to start working. When the bone conduction microphone assembly 130 detects that the sound is lower than the set value for more than the set time, the controller 150 controls the air conduction microphone 140 to start working. In this way, the bone conduction earphone 100 can avoid switching between the bone conduction microphone assembly 130 and the air conduction microphone 140 when the voice of the wearer 200 is temporarily increased or decreased, but the actual use environment has not changed.

[0088] The bone conduction earphone 100 provided by the embodiment of the present application is configured by the earphone body 110, the ear hook 120, the bone conduction microphone assembly 130, the air conduction microphone 140 and the controller 150. The bone conduction microphone assembly 130 comprises the first bone conduction microphone 131 and the second bone conduction microphone 132. The ear hook 120 is connected with the earphone body 110. The first bone conduction microphone 131 and the air conduction microphone 140 are both connected with the ear hook 120. The first bone conduction microphone 131 is configured to be attached to the zygomatic region 210 of the wearer 200. The air conduction microphone 140 is configured to be arranged close to the mouth 220 of the wearer 200. The second bone conduction microphone 132 is arranged on the earphone body 110. There is a gap between the second bone conduction microphone 132 and the back of the neck 230 of the wearer 200. The first bone conduction microphone 131, the second bone conduction microphone 132 and the air conduction microphone 140 are all electrically connected with the controller 150. When the sound is higher than the set value, the controller 150 controls the bone conduction microphone assembly 130 to start. The first bone conduction microphone 131 is configured to collect the voice of the wearer 200 and convert the voice into a first signal and transmit the first signal to the controller 150. The second bone conduction microphone 132 is configured to collect the ambient sound and convert the ambient sound into a second signal and transmit the second signal to the controller 150. The first signal converted from the sound collected by the first bone conduction microphone 131 mainly comprises the signal generated by the voice. The second signal converted from the sound collected by the second bone conduction microphone 132 mainly comprises the signal generated by the ambient sound. The controller 150 can easily shield the second signal and transmit the first signal, so that the bone conduction microphone assembly 130 has a better noise reduction effect, thereby making the bone conduction earphone 100 have a better sound collecting effect in a high noise environment. When the sound is lower than the set value, the controller 150 controls the air conduction microphone 140 to start. The air conduction microphone 140 is configured to collect the voice of the wearer and convert the voice into a third signal and transmit the third signal to the controller 150. The controller 150 is configured to transmit the third signal. The third signal converted from the sound collected by the air conduction microphone 140 mainly comprises the signal generated by the voice. The sensitivity and sound restoration degree of the air conduction microphone 140 are both high. The bone conduction earphone 100 has a better sound collecting effect in a low noise environment.

[0089] Next, the specific arrangement of the first bone conduction microphone 131 and the air conduction microphone 140 will be described.

[0090] Please continue to refer to Figure 1 and Figure 3 It is shown that the bone conduction earphone 100 further comprises an adapter rod 160. The adapter rod 160 is connected with the ear hook 120. The adapter rod 160 comprises a first side surface 161 and a first end surface 162. The first side surface 161 is attached to the zygomatic region 210 of the wearer 200. The first bone conduction microphone 131 is arranged on the first side surface 161. The first end surface 162 faces the mouth 220 of the wearer 200. The air conduction microphone 140 is arranged on the first end surface 162.

[0091] The adapter rod 160 can compensate for the gap between the ear hook 120 and the cheekbone area 210 of the wearer 200. The side of the adapter rod 160 facing away from the ear hook 120 is the first end face 162. The first end face 162 is closest to the mouth 220 of the wearer 200. The air conduction microphone 140 is set on the first end face 162, thereby making the air conduction microphone 140 closer to the sound source and able to collect the voice of the wearer 200 more timely and accurately.

[0092] The adapter rod 160 has a side that is in contact with the cheekbone region 210 and a first side 161. A first bone conduction microphone 131 is disposed on the first side 161 so that the first bone conduction microphone 131 can directly detect the vibration of the cheekbone region 210.

[0093] Figure 6 A schematic diagram of the structure of the bone conduction headphones provided in the embodiments of this application. Figure 2 ; Figure 7 This is a schematic diagram of the adapter rod in the bone conduction headphones provided in an embodiment of this application.

[0094] See Figure 6 and Figure 7 As shown, the adapter rod 160 includes a first telescopic section 163 and a second telescopic section 164. The first telescopic section 163 is connected to the ear hook 120 and can extend and retract relative to the ear hook 120. The second telescopic section 164 is connected to the first telescopic section 163 and can extend and retract relative to the first telescopic section 163. The first side 161 is the side of the first telescopic section 163 facing the cheekbone area 210 of the wearer 200, and the first end face 162 is the side of the second telescopic section 164 facing the mouth 220 of the wearer 200.

[0095] exist Figure 6 and Figure 7 In the illustrated embodiment, the adapter rod 160 is a telescopic rod, and the adapter rod 160 also includes a fixed section 165, which is used to connect the first telescopic section 163 and the lug 120. The first telescopic section 163 is a hollow cylindrical component, and its two ends are respectively sleeved on the fixed section 165 and the second telescopic section 164. The side wall of the first telescopic section 163 has a plurality of first through holes 1631 arranged at intervals along the extension direction of the first telescopic section 163. The first through holes 1631 are located close to the fixed section 165. The fixed section 165 has a first protrusion 1651, which is inserted into different first through holes 1631. The length of the first telescopic section 163 extending out of the fixed section 165 is different, thereby allowing the first telescopic section 163 to extend and retract relative to the fixed section 165, so that the distance between the first telescopic section 163 and the lug 120 is different.

[0096] The first side surface 161 is located on one side of the first telescopic section 163 facing the zygomatic region 210 of the wearer 200. When the first bone conduction microphone 131 is arranged on the first side surface 161, the distance between the first telescopic section 163 and the ear hook 120 can be adjusted according to different wearers 200, so that the first bone conduction microphone 131 can be attached to the zygomatic region 210 of the wearer 200 when the bone conduction earphone 100 is worn by different wearers 200, so that the vibration sensor in the first bone conduction microphone 131 can sensitively detect the vibration of the zygomatic bone when different wearers 200 speak.

[0097] The side wall of the first telescopic section 163 further has a plurality of second through holes 1632 arranged at intervals along the extension direction of the first telescopic section 163. The second through holes 1632 are arranged close to the second telescopic section 164. The second telescopic section 164 has a second protrusion 1641. The second protrusion 1641 is inserted into different second through holes 1632. The length of the second telescopic section 164 extending out of the first telescopic section 163 is different. Thus, the second telescopic section 164 can be telescoped relative to the first telescopic section 163, so that the distance between the second telescopic section 164 and the first telescopic section 163 is different.

[0098] The first end surface 162 is located on one side of the second telescopic section 164 facing the mouth 220 of the wearer 200. When the air conduction microphone 140 is arranged on the first end surface 162, the length of the second telescopic section 164 extending out of the first telescopic section 163 can be adjusted according to different wearers 200, so that the air conduction microphone 140 can be arranged as close to the mouth 220 of the wearer 200 as possible when the bone conduction earphone 100 is worn by different wearers 200, so as to timely and accurately collect the voice of different wearers 200 by the air conduction microphone 140.

[0099] In other embodiments, the first telescopic section 163 and the second telescopic section 164 can also be telescoped in other ways.

[0100] Figure 8 Structure diagram of the bone conduction earphone provided in the embodiments of the present application Figure 3 .

[0101] Referring to Figure 8 , the bone conduction earphone 100 includes two adapter rods 160, and the number of ear hooks 120 is two. The two adapter rods 160 are respectively connected to different ear hooks 120. One adapter rod 160 includes a second side surface 166, which is attached to the zygomatic region 210 of the wearer 200. The first bone conduction microphone 131 is arranged on the second side surface 166. The other adapter rod 160 includes a second end surface 167, which extends close to the mouth 220 of the wearer 200. The air conduction microphone 140 is arranged on the second end surface 167.

[0102] The two adapter rods 160 are arranged on the two hanging ears 120, so that the structure of the bone conduction earphone 100 is symmetrical and beautiful. The second side surface 166 of one adapter rod 160 is arranged with the first bone conduction microphone 131, and the second end surface 167 of the other adapter rod 160 is arranged with the air conduction microphone 140, so that the first bone conduction microphone 131 and the air conduction microphone 140 are not interfered with each other.

[0103] It should be noted that, in the embodiment shown in the figure, Figure 8 In the embodiment shown in the figure, the lengths of the two adapter rods 160 can be adjusted.

[0104] In addition, in the embodiment, the adapter rod 160 can be made of titanium metal or spring steel or other materials with high elasticity, so that the adapter rod 160 has high elasticity. The adapter rod 160 is arranged to be curved towards the zygomatic region 210 of the wearer 200 and to apply elastic force to the face of the wearer 200, so that the first bone conduction microphone 131 is tightly attached to the zygomatic region 210 of the wearer 200 and the air conduction microphone 140 can be closer to the mouth 220 of the wearer 200.

[0105] Please continue to refer to Figure 2 and Figure 4 As shown in the figure, the bone conduction earphone 100 further comprises a bone conduction speaker 170, the end of the hanging ear 120 away from the earphone body 110 is provided with a second mounting portion 121, and the bone conduction speaker 170 is arranged on the second mounting portion 121. The bone conduction speaker 170 is electrically connected with the controller 150.

[0106] The second mounting portion 121 is connected with the hanging ear 120, and when the hanging ear 120 is hung on the ear 240 of the wearer 200, the side of the second mounting portion 121 provided with the bone conduction speaker 170 is attached to the skull region 250 of the wearer 200.

[0107] The bone conduction speaker 170 is used to play the audio received by the bone conduction earphone 100. Specifically, the controller 150 of the bone conduction earphone 100 processes the audio received by the bone conduction earphone 100, converts it into a fifth signal and transmits it to the bone conduction speaker 170. The bone conduction speaker 170 converts the fifth signal into a specific vibration frequency and transmits it to the auditory center of the wearer through the skull, the bone labyrinth, the endolymph, and the cochlea.

[0108] The bone conduction speaker 170 does not need to be deeply inserted into the inside of the ear 240 of the wearer 200, so that the problem of pain in the ear 240 of the wearer 200 caused by long-term wearing of the earphone can be avoided.

[0109] In the embodiment, the adapter rod 160 is connected with the second mounting portion 121 and can rotate relative to the second mounting portion 121. The adapter rod 160 is connected to the hanger 120 through the second mounting portion 121, which can simplify the structure of the hanger 120, so that the consistency of the overall structure of the bone conduction earphone 100 is good.

[0110] The second mounting portion 121 can be provided with a mounting hole, and one end of the adapter rod 160 towards the second mounting portion 121 can be provided with a rotating shaft. The rotating shaft is inserted into the mounting hole and is in interference fit with the mounting hole, so that the adapter rod 160 can rotate relative to the second mounting portion 121 and can stop rotating at a set position. Thus, different wearers 200 can adjust the specific position of the first bone conduction microphone 131 connected with the adapter rod 160 by rotating the adapter rod 160 relative to the second mounting portion 121 according to the specific position of the malar region 210, so that the first bone conduction microphone 131 can be tightly attached to the malar region 210 of the wearer 200.

[0111] Please continue to see Figure 2 As shown, the bone conduction earphone 100 further includes a battery 180, and the earphone body 110 has a third mounting portion 112, and the battery 180 is located in the third mounting portion 112.

[0112] The battery 180 is used to power the first bone conduction microphone 131, the second bone conduction microphone 132, the air conduction microphone 140, the bone conduction speaker 170 and the controller 150 in the bone conduction earphone 100.

[0113] The battery 180 is mounted on the earphone body 110. Specifically, the earphone body 110 has a third mounting portion 112, and the battery is mounted in the third mounting portion 112 of the earphone body 110. It should be noted that the battery 180 is located in the third mounting portion 112, Figure 2 The battery 180 is schematically shown in a filled rectangular frame.

[0114] In the embodiment, the third mounting portion 112 and the first mounting portion 111 are oppositely arranged at both ends of the earphone body 110 in the extension direction of the earphone body 110, so that the bone conduction earphone 100 remains beautiful, and the weight of the earphone body 110 at both ends can be similar, so that the pressure borne by both ears of the wearer 200 when wearing the bone conduction earphone 100 is similar, and the comfort of the wearer 200 when wearing the bone conduction earphone 100 is improved.

[0115] Please continue to see Figure 1 , Figure 6 and Figure 8As shown, in the present embodiment, the controller 150 is arranged in the first mounting portion 111. The controller 150 includes a circuit board and a control chip arranged on the circuit board, and the first bone conduction microphone 131, the second bone conduction microphone 132, the air conduction microphone 140 and the bone conduction speaker 170 are all electrically connected with the control chip through internal wiring of the circuit board. Since the weight of the battery 180 is usually large, the controller 150 is arranged in the first mounting portion 111, so as to balance the weight of the first mounting portion 111 and the third mounting portion 112. It should be noted that the controller 150 is located in the first mounting portion 111, Figure 1 、 Figure 6 and Figure 8 The controller 150 is schematically shown in a filled rectangular frame in the first mounting portion 111, the second mounting portion 121 and the third mounting portion 112.

[0116] In other embodiments, the controller 150 can also be arranged in one of the second mounting portion 121 and the third mounting portion 112.
