[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] In the related art, the receiving microphone is an air conduction microphone. In a high-noise environment, the receiving microphone will also collect ambient sound, making it difficult for the controller to separate and process the ambient sound. After separating and processing the ambient sound, the human voice will become very small, making the noise reduction effect of the bone conduction headset poor.

[0047] Based on this, the present application provides a bone conduction headset, which has a good noise reduction effect.

[0049] 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 first microphone 130, a second microphone 140 and a controller 150; the first microphone 130 and the second microphone 140 are both bone conduction microphones, the ear hook 120 is connected to the earphone body 110, the first microphone 130 is connected to the ear hook 120, and the first microphone 130 is used to fit the cheekbone area 210 of the wearer 200; the second microphone 140 is arranged on the earphone body 110, and there is a gap between the second microphone 140 and the back of the neck 220 of the wearer.

[0050] The first microphone 130 and the second microphone 140 are both electrically connected to the controller 150; the first microphone 130 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 microphone 140 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 to transmit the first signal.

[0051] First, the wearing method of the bone conduction earphone 100 provided in the embodiment of the present application is described.

[0052] 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 230 of the wearer 200, and the earphone body 110 is wrapped around the back neck 220 of the wearer 200.

[0053] Next, the configuration of the first microphone 130 is described.

[0054] The bone conduction microphone is 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 opens and closes, the zygomatic area 210, the mandible or the mandible will vibrate as the mouth opens and closes. The first microphone 130 can be attached to one of the zygomatic area 210, the maxilla or the mandible, and the vibration sensor in the first microphone 130 converts the vibration of the zygomatic area 210, the maxilla or the mandible into an electrical signal.

[0055] However, the maxillary and mandibular bones have large ranges of motion, and it is not convenient to install a bone conduction microphone there. Therefore, in this embodiment, the first microphone 130 is fitted with the zygomatic region 210 of the wearer 200. When the wearer 200 speaks, the vibration sensor in the first microphone 130 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.

[0056] Next, the arrangement of the second microphone 140 is described.

[0057] The vibration sensor in the second microphone 140 is used to convert the vibration generated by the ambient sound into a second signal and transmit it to the controller 150 .

[0058] In order to prevent the vibration generated when the wearer 200 speaks from being transmitted to the vibration sensor in the second microphone 140 , the second microphone 140 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 .

[0059] In this embodiment, the earphone body 110 is wrapped around the back neck 220 of the wearer 200, and the earphone body 110 is separated from the first microphone 130 by the ear hook 120. Therefore, the second microphone 140 is connected to the earphone body 110 so that the second microphone 140 is close to the back neck 220 of the wearer 200, so that the second microphone 140 can be set away from the cheekbone area 210 of the wearer 200.

[0060] The gap between the second microphone 140 and the back of the neck of the wearer 200 can be achieved in the following two ways.

[0061] 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 220 of the wearer 200, and the second microphone 140 is mounted on the connecting rod, and the second microphone 140 is connected to the earphone body 110 through the connecting rod, and the connecting rod can allow a gap between the second microphone 140 and the back of the neck 220 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 microphone 140. However, the provision of the connecting rod on the earphone body 110 will affect the overall aesthetics of the bone conduction earphone 100.

[0062] In another possible embodiment, the contour of the earphone body 110 is consistent with the contour of the back neck 220 of the wearer 200, and there is a gap between the earphone body 110 and the back neck 220 of the wearer 200. The earphone body 110 has a first mounting portion 111, and the second microphone 140 is arranged on a side of the first mounting portion 111 facing away from the back neck 220 of the wearer 200.

[0063] Please continue to see Figure 3 As shown, the earphone body 110 and the back neck 220 of the wearer 200 are concentric arcs and the diameter of the earphone body 110 is slightly larger than the diameter of the back neck 220 of the wearer 200, thereby, there is a gap between the earphone body 110 and the back neck 220 of the wearer 200, so that there is a gap between the second microphone 140 arranged on the first mounting portion 111 of the earphone body 110 and the back neck 220 of the wearer 200.

[0064] In order for the second microphone 140 to collect ambient sound, the second microphone 140 needs to face away from the back neck 220 of the wearer 200 . In this embodiment, the second microphone 140 is disposed on a side of the first mounting portion 111 facing away from the back neck 220 of the wearer 200 .

[0065] 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 220 of the wearer 200 and the earphone body 110.

[0066] Next, the working process of the first microphone 130 , the second microphone 140 and the controller 150 will be described.

[0067] Since the first microphone 130 is in close contact with the zygomatic region 210 of the wearer 200, when the wearer 200 speaks, the vibration sensor in the first microphone 130 can sensitively detect the vibration of the zygomatic region when the wearer 200 speaks, and convert the vibration of the zygomatic region into a first signal and then output it to the controller 150. When the vibration generated by the ambient sound is transmitted to the first microphone 130, 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 setting the first microphone 130 that collects the sound of the wearer 200 as a bone conduction microphone and making the first microphone 130 in close contact with the zygomatic region 210 of the wearer 200, the ambient sound collected by the first microphone 130 is much smaller than the human voice. The first signal converted from the sound collected by the first microphone 130 is mainly the signal generated by the human voice.

[0068] Since the second microphone 140 is arranged far away from the first microphone 130 and there is a gap between it and the wearer 200, it is difficult for the vibration sensor in the second microphone 140 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 microphone 140 is much smaller than the ambient sound, and the second signal converted from the sound collected by the second microphone 140 is mainly the signal generated by the ambient sound.

[0069] Since the first signal is mainly composed of signals generated by human voices, and the second signal is mainly composed of signals generated by ambient sounds, the controller 150 is used to generate a third signal that is opposite to the second signal based only on the second signal to offset the second signal, thereby shielding the second signal with little impact on the first signal generated by human voices, thereby having a good noise reduction effect.

[0070] The bone conduction headset 100 provided in the embodiment of the present application is provided with an earphone body 110, an ear hook 120, a first microphone 130, a second microphone 140 and a controller 150; the ear hook 120 is connected to the earphone body 110, the first microphone 130 is a bone conduction microphone, the first microphone 130 is connected to the ear hook 120, and the first microphone 130 is in contact with the zygomatic area 210 of the wearer 200, the first microphone 130 is electrically connected to the controller 150, the first microphone 130 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, because the first microphone 130 is in contact with the zygomatic area 210 of the wearer 200, therefore, the first microphone 130 can sensitively detect the vibration generated by the zygomatic bone when the wearer 200 speaks, The ambient sound collected by the first microphone 130 is much smaller than the human voice, and the first signal converted from the sound collected by the first microphone 130 is mainly the signal generated by the human voice; the second microphone 140 is arranged on the earphone body 110, and there is a gap between the second microphone 140 and the back neck 220 of the wearer, the second microphone 140 is electrically connected to the controller, and the second microphone 140 is used to collect ambient sound and convert the ambient sound into a second signal to transmit to the controller 150. Since there is a gap between the second microphone 140 and the wearer 200, the human voice collected by the second microphone 140 is much smaller than the ambient sound, and the second signal converted from the sound collected by the second microphone 140 is mainly the signal generated by the ambient sound. The controller 150 only needs to shield the second signal to achieve a better noise reduction effect.

[0071] Please continue to see Figure 1 and Figure 2 As shown, the bone conduction headset 100 also includes a transfer rod 160, which is connected to the ear hook 120, and the transfer rod 160 is a telescopic rod. One side of the transfer rod 160 fits the zygomatic area 210 of the wearer 200, and the first microphone 130 is arranged on the side of the transfer rod 160 facing the zygomatic area 210 of the wearer 200.

[0072] The adapter rod 160 can compensate for the distance between the ear hook 120 and the zygomatic region 210 of the wearer 200. In this embodiment, the adapter rod 160 is a telescopic rod, and the length of the adapter rod 160 can be adjusted to be suitable for different wearers 200. Specifically, when the wearer 200 wears the bone conduction headset 100, the length of the adapter rod 160 is adjusted so that the end of the adapter rod 160 away from the ear hook 120 fits on the zygomatic region 210 of the wearer 200. The first microphone 130 is arranged toward the zygomatic region 210 of the wearer 200 so that the first microphone 130 directly detects the vibration of the zygomatic region 210.

[0073] In this embodiment, the transfer rod 160 is an elastic metal piece, which is configured to bend toward the zygomatic area 210 of the wearer 200 and apply elastic force toward the zygomatic area 210 of the wearer 200 so that the first microphone 130 is in close contact with the zygomatic area 210 of the wearer 200 .

[0074] 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 an arc-shaped member that is bent toward the zygomatic region 210 of the wearer 200. The curvature of the transfer rod 160 is slightly smaller than the curvature of the zygomatic region 210 of the wearer 200. When the transfer rod 160 is attached to the zygomatic region of the wearer 200, the transfer rod 160 applies pressure to the zygomatic region 210 of the wearer 200 due to the curvature of the transfer rod 160 and the elastic force of the transfer rod 160 itself, thereby allowing the first microphone 130 to be closely attached to the zygomatic region 210 of the wearer 200, so that the first microphone 130 can detect the vibration of the zygomatic region 210 more sensitively.

[0075] See also 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 .

[0076] The second mounting portion 121 is connected to the ear hook 120 . When the ear hook 120 is hooked on the ear 230 of the wearer 200 , a surface of the second mounting portion 121 provided with the bone conduction speaker 170 fits against the skull region 240 of the wearer 200 .

[0077] 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 fourth signal and transmits it to the bone conduction speaker 170. The bone conduction speaker 170 converts the fourth 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.

[0078] The bone conduction speaker 170 does not need to penetrate into the ear 230 of the wearer 200, and thus, the problem of pain in the ear 230 caused by the wearer 200 wearing the earphone for a long time can be avoided.

[0079] In this embodiment, the adapter rod 160 is connected 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.

[0080] In this embodiment, the transfer rod 160 can rotate relative to the second mounting portion 121 .

[0081] The second mounting portion 121 may be provided with a mounting hole, and the 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 microphone 130 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 microphone 130 can be close to the zygomatic region 210 of the wearer 200.

[0082] 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 .

[0083] The battery 180 is used to power the first microphone 130 , the second microphone 140 , the bone conduction speaker 170 and the controller 150 in the bone conduction headset 100 .

[0084] 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 as a filled rectangular box.

[0085] 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.

[0086] Please continue to see Figure 1 As 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 microphone 130, the second microphone 140 and the bone conduction speaker 170 are electrically connected to the control chip through the internal wiring of the circuit board. Since the weight of the battery 180 is usually 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 The controller 150 is schematically shown as a filled rectangular box.

[0087] In other embodiments, the controller 150 may also be disposed in one of the second mounting portion 121 and the third mounting portion 112 .

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
