[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to 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", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

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

[0046] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or service tool that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or service tool.

[0047] Bone conduction is a method of sound conduction, which converts sound into mechanical vibrations of different frequencies and transmits sound waves through the human skull, bony labyrinth, inner ear lymph, spiral organ, and auditory center.

[0048] Bone conduction headphones include bone conduction speakers, which convert electrical signals into sound waves and transmit them directly to the auditory nerve through the bones. Since the step of sound wave transmission in the air is omitted, the person wearing the headphones (referred to as the wearer) can clearly hear the sound emitted by the bone conduction speakers even in a noisy environment.

[0049] The bone conduction headset also includes a sound receiving microphone, a noise reduction microphone and a controller. The sound receiving microphone and the noise reduction microphone are both electrically connected to the controller. The sound 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 sound 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, thereby achieving the effect of noise reduction.

[0050] In the related art, the sound receiving microphone and the noise reduction microphone are air conduction microphones. In a high-noise environment, the sound receiving microphone will also collect noise, making it difficult for the controller to separate and process the ambient sound, and after the ambient sound is separated and processed, the human voice will become very small. In a low-noise environment, the noise reduction microphone will also collect the human voice, and the controller will also subtract part of the human voice collected by the noise reduction microphone during the noise reduction process, making the human voice also become very small. Therefore, the sound receiving effect of bone conduction headphones in both high-noise and low-noise environments is poor.

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

[0053] See also Figures 1 to 4 As shown, the bone conduction headset 100 provided in the present 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 there is a gap between the second bone conduction microphone 132 and the back 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 human voice of the wearer 200 and convert the human voice into a first signal and transmit it to the controller 150, the second bone conduction microphone 132 is used to collect ambient sound and convert the ambient sound into a second signal and transmit it to the controller 150, and the controller 150 is used to shield the second signal and 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 up. The air conduction microphone 140 is used to collect the wearer's voice and convert the voice into a third signal and transmit it 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 in the embodiment of the present application is described.

[0057] Please continue to participate Figures 1 to 3 As shown, the earphone body 110 is approximately U-shaped, and the ear hooks 120 are connected to both ends of the earphone body 110. When the wearer 200 wears the bone conduction earphone 100, the ear hooks 120 are hung on the ears 240 of the wearer 200, and the earphone body 110 is wrapped around the back neck 230 of the wearer 200.

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

[0059] The bone conduction microphone assembly 130 includes a first bone conduction microphone 131 and a 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 first bone conduction microphone 131 and the second bone conduction microphone 132 are both provided with a vibration sensor, which receives the vibration of the sound source and converts the vibration of the sound source into an electrical signal. When the wearer 200 speaks, as the mouth 220 opens and closes, the zygomatic region 210, the mandible or the mandible vibrates 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 mandible, and the vibration sensor in the first bone conduction microphone 131 converts the vibration of the zygomatic region 210, the maxilla or the mandible into an electrical signal.

[0061] However, the maxillary and mandibular bones have large movement ranges, and it is not convenient to install a bone conduction microphone at the maxillary and mandibular bones. Therefore, in this embodiment, the first bone conduction microphone 131 is fitted with 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 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 configuration of the second bone conduction microphone 132 is described.

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

[0064] In order to prevent the vibration generated by the wearer 200 when speaking 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 cheekbone area 210 of the wearer 200 and also needs to have a gap between it and the head of the wearer 200 .

[0065] In this embodiment, the earphone body 110 is wrapped around the back 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. Therefore, 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 neck 230 of the wearer 200, so that the second bone conduction microphone 132 can be set away from the cheekbone area 210 of the wearer 200.

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

[0067] In some possible implementations, the earphone body 110 may be provided with a connecting rod, which extends from the earphone body 110 away from the back of the neck 230 of the wearer 200, and the second bone conduction microphone 132 is mounted on the connecting rod, and the second bone conduction microphone 132 is connected to the earphone body 110 through the connecting rod, and the connecting rod can allow a gap between the second bone conduction microphone 132 and the back of the neck 230 of the wearer 200. In this way, the vibration generated when the wearer 200 speaks can be prevented from being transmitted to the vibration sensor in the second bone conduction microphone 132. However, the provision of the connecting rod on the earphone body 110 will affect the overall aesthetics of the bone conduction earphone 100.

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

[0069] Please continue to see Figure 3 As shown, the earphone body 110 and the back of the neck 230 of the wearer 200 are concentric arcs and the diameter of the earphone body 110 is slightly larger than the diameter of the back of the neck 230 of the wearer 200. As a result, there is a gap between the earphone body 110 and the back of the neck 230 of the wearer 200, so that there is a gap between the second bone conduction microphone 132 arranged on the first mounting portion 111 of the earphone body 110 and the back of the 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 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 set to a retractable structure. By adjusting the retractable structure in the earphone body 110, when different wearers 200 wear the bone conduction earphone 100, there is a gap between the back neck 230 of the wearer 200 and the earphone body 110.

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

[0073] Figure 5 Schematic diagram of the internal structure of an air conduction microphone.

[0074] See also Figure 5As shown, the air conduction microphone 140 includes a diaphragm 141 , a metal plate 142 and a field effect transistor 143 . The diaphragm 141 carries an electric charge. The diaphragm 141 and the metal plate 142 form an air capacitor 144 . The field effect transistor 143 is electrically connected to the air capacitor 144 .

[0075] When the wearer 200 makes a sound, the sound waves of the wearer 200 are transmitted to the diaphragm 141. The diaphragm 141 vibrates with the change of the sound waves, causing the capacity of the air capacitor 144 to change, thereby causing the voltage to change, forming an electrical signal. The field effect transistor 143 amplifies the electrical signal and then transmits it.

[0076] The sensor in the air conduction microphone 140 is a capacitive sensor, so the air conduction microphone 140 is relatively sensitive. In addition, the air conduction microphone 140 directly transmits sound waves. Compared with the bone conduction microphone that transmits sound through bone vibration, the air conduction microphone 140 has a higher degree of sound restoration than the bone conduction microphone.

[0077] The bone conduction earphone 100 provided in the embodiment of the present application utilizes the different characteristics of the bone conduction microphone and the air conduction microphone. The bone conduction microphone assembly 130 is used to collect sound in a high-noise environment, and the air conduction microphone 140 is used to collect sound in a low-noise environment. This enables the bone conduction earphone 100 to have a good sound collection 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 this embodiment, the initial setting of the bone conduction headset 100 is, for example, that the air conduction microphone 140 is working, and the air conduction microphone 140 can also detect the decibel value of the sound. A sound setting value is set in the controller 150, and the sound setting value can be, for example, 70db-80db.

[0080] Specifically, in a noisy environment, when the air conduction microphone 140 detects that the sound is higher than the set 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 bone generated when the wearer 200 speaks, and converts the vibration of the zygomatic bone into a first signal and then outputs 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 its vibration is much smaller than the amplitude generated by the vibration of the zygomatic region 210. Therefore, at the source of the sound collection, by attaching the first bone conduction microphone 131 for collecting 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 first signal converted from the sound collected by the first bone conduction microphone 131 is mainly the signal generated by the human voice.

[0082] Since the second bone conduction microphone 132 is arranged far away from the first bone conduction microphone 131 and there is a gap between it and the wearer 200, it is difficult for the vibration sensor in the second bone conduction microphone 132 to detect the vibration generated by the cheekbones of the wearer 200. Therefore, at the source of the sound collection, the human voice collected by the second bone conduction microphone 132 is much smaller than the ambient sound, and the second signal converted from the sound collected by the second bone conduction microphone 132 is mainly the signal generated by the ambient sound.

[0083] Since the first signal is mainly generated by human voice, and the second signal is mainly generated by ambient sound, the controller 150 only generates a fourth signal which is opposite to the second signal according to the second signal to offset the second signal, thereby shielding the second signal, while having little impact on the first signal generated by human voice, so that the bone conduction microphone assembly 130 has a better noise reduction effect, thereby enabling the bone conduction earphone 100 to have a better sound reception 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 use environment with low noise, when the bone conduction microphone assembly 130 detects that the sound is higher than or lower 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 the air capacitor 144 in the air conduction microphone 140 can timely and accurately collect the human voice of the wearer 200. Since the ambient noise is relatively small, when the sound waves formed by the ambient sound are transmitted to the air conduction microphone 140, due to the transmission attenuation of the air medium, the amplitude of its vibration is much smaller than the sound waves generated by the voice of the wearer 200. Therefore, the third signal converted from the sound collected by the air conduction microphone 140 is mainly a signal generated by the human voice, and no noise reduction processing is required, so that the bone conduction earphone 100 can have a good sound collection effect in a low-noise environment.

[0087] It should be noted that, in some embodiments, the controller 150 is also provided with a set time, which may be, for example, 10s-20s. When the air conduction microphone 140 detects that the sound is higher than the set value for a time exceeding 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 a time exceeding the set time, the controller 150 controls the air conduction microphone 140 to start working. This setting can prevent the bone conduction headset 100 from switching between the bone conduction microphone assembly 130 and the air conduction microphone 140 when the wearer's 200 voice is temporarily increased or decreased and the actual use environment has not changed.

[0088] The bone conduction earphone 100 provided in the embodiment of the present application is provided with 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 there is a gap between the second bone conduction microphone 132 and the back 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. 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 human voice of the wearer 200 and convert the human voice into a first signal and transmit it to the controller 150, the second bone conduction microphone 132 is used to collect ambient sound and convert the ambient sound into a second signal and transmit it to the controller 150, the first signal converted from the sound collected by the first bone conduction microphone 131 is mainly a signal generated by the human voice, and the second signal converted from the sound collected by the second bone conduction microphone 132 is mainly a 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, so that the bone conduction headset 100 has a better sound reception 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 used to collect the wearer's voice and convert the voice into a third signal and transmit it to the controller 150. The controller 150 is used to transmit the third signal. The third signal converted from the sound collected by the air conduction microphone 140 is mainly a signal generated by the human voice. The air conduction microphone 140 has high sensitivity and sound restoration. The bone conduction headset 100 has a good sound reception effect in a low-noise environment.

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

[0090] Please continue to see Figure 1 and Figure 3 As shown, the bone conduction headset 100 also includes a transfer rod 160, which is connected to the ear hook 120. The transfer rod 160 includes a first side surface 161 and a first end surface 162. The first side surface 161 fits the zygomatic area 210 of the wearer 200, and 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, and the air conduction microphone 140 is arranged on the first end surface 162.

[0091] The adapter rod 160 can compensate for the distance 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 a first end surface 162. The first end surface 162 is closest to the mouth 220 of the wearer 200. The air conduction microphone 140 is arranged on the first end surface 162. Therefore, the air conduction microphone 140 is closer to the sound source, and the human voice of the wearer 200 can be collected more timely and accurately.

[0092] The side of the adapter rod 160 that is in contact with the zygomatic area 210 is in contact with the first side surface 161 , and the first bone conduction microphone 131 is disposed on the first side surface 161 , so that the first bone conduction microphone 131 can directly detect the vibration of the zygomatic area 210 .

[0093] Figure 6 Schematic diagram of the structure of the bone conduction headset provided in the embodiment of the present application Figure 2 ; Figure 7 This is a schematic diagram of the structure of the adapter rod in the bone conduction earphone provided in an embodiment of the present application.

[0094] See also 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 be telescopic relative to the ear hook 120, the second telescopic section 164 is connected to the first telescopic section 163 and can be telescopic relative to the first telescopic section 163, the first side surface 161 is a side of the first telescopic section 163 facing the cheekbone area 210 of the wearer 200, and the first end surface 162 is a 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 transfer rod 160 is a telescopic rod, and the transfer rod 160 further includes a fixed section 165, which is used to connect the first telescopic section 163 and the hanging ear 120. The first telescopic section 163 is a hollow cylindrical member, and the two ends of the first telescopic section 163 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, and the first through holes 1631 are arranged close to the fixed section 165. The fixed section 165 has a first protrusion 1651, and the first protrusion 1651 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, so that the first telescopic section 163 can be telescoped relative to the fixed section 165, so that the spacing between the first telescopic section 163 and the hanging ear 120 is different.

[0096] The first side surface 161 is located on a side of the first telescopic section 163 facing the zygomatic area 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 when different wearers 200 wear the bone conduction headset 100, the first bone conduction microphone 131 can fit the zygomatic area 210 of the wearer 200, so that the vibration sensor in the first bone conduction microphone 131 can sensitively detect the vibration generated by the zygomatic bone when different wearers 200 speak.

[0097] The side wall of the first telescopic section 163 also 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 second telescopic section 164 extends out of the first telescopic section 163 to different lengths. Therefore, the second telescopic section 164 can be telescoped relative to the first telescopic section 163 so that the spacing between the second telescopic section 164 and the first telescopic section 163 is different.

[0098] The first end surface 162 is located on a side of the second telescopic section 164 facing the mouth 220 of the wearer 200. When the air conduction microphone 140 is set 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 when different wearers 200 wear the bone conduction earphone 100, the air conduction microphone 140 can be set as close to the mouth 220 of the wearer 200 as possible, so as to collect the human voices of different wearers 200 in a timely and accurate manner with the air conduction microphone 140.

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

[0100] Figure 8 Schematic diagram of the structure of the bone conduction headset provided in the embodiment of the present application Figure 3 .

[0101] See also Figure 8 As shown, the bone conduction headset 100 includes two adapter rods 160, the number of the ear hooks 120 is two, and the two adapter rods 160 are respectively connected to different ear hooks 120; one adapter rod 160 includes a second side surface 166, the second side surface 166 fits the cheekbone area 210 of the wearer 200, and 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, the second end surface 167 extends to the mouth 220 close to the wearer 200, and the air conduction microphone 140 is arranged on the second end surface 167.

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

[0103] It should be noted that in Figure 8 In the illustrated embodiment, the lengths of both transfer rods 160 are adjustable.

[0104] In addition, in this embodiment, the transfer rod 160 can be made of a material with high elasticity such as titanium or spring steel, so that the transfer rod 160 has high elasticity. The transfer rod 160 is configured to bend toward the zygomatic region 210 of the wearer 200 and apply elastic force toward the face of the wearer 200, so that the first bone conduction microphone 131 is closely 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 see Figure 2 and Figure 4 As shown, the bone conduction earphone 100 also includes a bone conduction speaker 170 , a second mounting portion 121 is provided at one end of the ear hook 120 away from the earphone body 110 , the bone conduction speaker 170 is provided on the second mounting portion 121 , and the bone conduction speaker 170 is electrically connected to the controller 150 .

[0106] The second mounting portion 121 is connected to the ear hook 120 . When the ear hook 120 is hooked on the ear 240 of the wearer 200 , a surface of the second mounting portion 121 provided with the bone conduction speaker 170 fits against 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 headset 100. Specifically, the controller 150 of the bone conduction headset 100 processes the audio received by the bone conduction headset 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, bony labyrinth, inner ear lymph and spiral organ.

[0108] The bone conduction speaker 170 does not need to penetrate into the ear 240 of the wearer 200, and thus, the problem of pain in the ear 240 caused by the wearer 200 wearing the earphone for a long time can be avoided.

[0109] In this embodiment, the adapter rod 160 is connected to the second mounting portion 121 and can rotate relative to the second mounting portion 121. The adapter rod 160 is connected to the ear hook 120 through the second mounting portion 121, which can simplify the structure of the ear hook 120 and make the overall structure of the bone conduction earphone 100 more consistent.

[0110] The second mounting portion 121 may be provided with a mounting hole, and one end of the adapter rod 160 facing the second mounting portion 121 may be provided with a rotating shaft, which is inserted into the mounting hole and has an 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 to the adapter rod 160 by rotating the adapter rod 160 relative to the second mounting portion 121 according to the specific position of the zygomatic region 210, so that the first bone conduction microphone 131 can be close to the zygomatic 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 . 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 headset 100 .

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

[0114] In this embodiment, the third mounting portion 112 and the first mounting portion 111 are arranged opposite to each other at both ends of the extension direction of the earphone body 110, so that the bone conduction earphone 100 maintains its appearance, and the weight of the two ends of the earphone body 110 can be similar, so that when the wearer 200 wears the bone conduction earphone 100, the pressure on both ears is similar, thereby improving the comfort of the wearer 200 when wearing the bone conduction earphone 100.

[0115] Please continue to see Figure 1 , Figure 6 and Figure 8As shown, in this embodiment, the controller 150 is disposed in the first mounting portion 111. The controller 150 includes a circuit board and a control chip disposed on the circuit board. 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 to the control chip through the internal wiring of the circuit board. Since the weight of the battery 180 is generally large, the controller 150 is disposed in the first mounting portion 111 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 the filled rectangular box.

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