Description

Technical Field

[0001] This invention relates to the technical field of bone conduction headphones, and particularly to a bone conduction communication component and helmet. Background Technology

[0002] In modern society, bone conduction is widely used in the field of communications. It converts sound into mechanical vibrations of different frequencies, transmitting sound waves through the skull, bony labyrinth, inner ear fluid, cochlea, and auditory center. Compared to the classic sound conduction method that generates sound waves through a diaphragm, bone conduction eliminates many steps in sound wave transmission, enabling clear sound reproduction even in noisy environments, and the sound waves do not affect others due to airborne diffusion. The combination of bone conduction technology and wearable devices has greatly facilitated daily life, work, and entertainment.

[0003] Currently, bone conduction communication devices on the market use a simple combination of a shell and bone conduction headphones. The bone conduction headphones are mounted on the shell as a fixed component. The positions of the bone conduction microphone and speaker are mostly fixed. External noise can also easily affect the quality of bone conduction communication through the shell. Since bone conduction relies on the skull for transmission, different contact points between the bone conduction components and the body result in different quality of the received sound signal. During use, it is necessary to constantly adjust the contact point by wearing the device, which is quite troublesome. Summary of the Invention

[0004] The main objective of this invention is to provide a bone conduction communication component that can adaptively adjust the contact points according to the size of the user's head.

[0005] To achieve the above objectives, the present invention proposes a bone conduction communication component, applied to a housing, comprising:

[0006] The support unit includes a top support and a fixed support. The fixed support fixes the bone conduction communication component to the housing. The fixed support is rotatably connected to the top support. An elastic structure is provided at the rotatable connection between the fixed support and the top support. The elastic structure is used to make the top support have a tendency to rotate toward the middle of the housing.

[0007] A bone conduction microphone is mounted on the top of the head support.

[0008] Bone conduction sound emitter, disposed in the support portion; and

[0009] The communication module is located in the support section and is electrically connected to both the bone conduction pickup and the bone conduction amplifier.

[0010] Optionally, the elastic structure is a spring or a torsion spring, one end of which is fixedly connected to the fixed bracket and the other end is fixedly connected to the top bracket. The torsion spring or spring has torsional potential energy, which causes the top bracket to have a tendency to rotate toward the middle of the shell.

[0011] Optionally, the head support includes a first support segment located above the rotation position and a second support segment located below the rotation position, the bone conduction pickup is disposed in the first support segment, and the bone conduction amplifier is disposed in the second support segment; the elastic structure is used to give the first support segment a tendency to rotate toward the middle of the housing.

[0012] Optionally, the inner side of the first bracket segment is provided with a mounting groove, the bone conduction microphone is disposed in the mounting groove, and the groove opening of the mounting groove is covered with a soft rubber part.

[0013] Optionally, the bone conduction amplifier includes a rocker arm and a vibrator, one end of the rocker arm being rotatably connected to the second support segment, and the vibrator being disposed at the other end of the rocker arm; and / or,

[0014] The other end of the rocker arm is also provided with a bone conduction housing, and the vibrator is installed inside the bone conduction housing.

[0015] Optionally, the second bracket segment is provided with a shaft protrusion, and the shaft protrusion is provided with a limiting protrusion. The rocker arm is provided with a rotating groove corresponding to the shaft protrusion. The rotating groove is provided with a plurality of limiting grooves distributed circumferentially. The limiting protrusion can switch between the plurality of limiting grooves.

[0016] Optionally, the fixing bracket is fixed to the housing by bolts; and / or,

[0017] The fixed bracket is provided with a first clamping block and a second clamping block for clamping onto the housing. A V-groove is formed at the connection between the first clamping block and the second clamping block. The first clamping block and the second clamping block are connected by bolts passing through the V-groove.

[0018] Optionally, the bone conduction communication component further includes:

[0019] A control box is located on the bracket portion, and the communication module is located on the control box; and / or,

[0020] Searchlight box, located in the bracket portion; and / or,

[0021] The control box and / or the searchlight box are provided with a hanging slot, and the bracket is provided with a hook. The control box and / or the searchlight box are installed on the bracket through the fastening cooperation of the hanging slot and the hook.

[0022] Optionally, the bracket portion is provided with a wiring channel, through which the wires of the control box pass to connect to the bone conduction amplifier.

[0023] A helmet having the aforementioned bone conduction communication component.

[0024] Optionally, a clearance space is provided on the inner side of the helmet at the position corresponding to the top support.

[0025] The technical solution of this invention features an elastic structure at the rotational position of the headrest and the housing. This elastic structure possesses torsional force, causing the headrest to tend to rotate towards the center of the housing, and consequently, towards the user's head. When the user places the housing on their head, the head presses against the headrest. The elastic structure adaptively adjusts the rotation angle of the headrest according to the size of the user's head, thereby adjusting the contact point between the bone conduction microphone and the user's head. This invention allows for adaptive adjustment of the contact point based on the size of the user's head. A clearance ensures that the headrest does not contact the helmet during rotation, preventing sound from the helmet from interfering with the sound propagation of the bone conduction microphone and amplifier.

[0042] This invention proposes a bone conduction communication component.

[0043] In embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the bone conduction communication component includes a support portion 100, a bone conduction microphone 600, a bone conduction amplifier 200, and a communication module. The support portion 100 includes a headrest 120 and a fixing bracket 130. The fixing bracket 130 fixes the bone conduction communication component to the housing 110; that is, the bone conduction communication component is fixed to the housing 110 via the fixing bracket 130. The fixing bracket 130 is rotatably connected to the headrest 120. An elastic structure is provided at the rotatable connection between the fixing bracket and the headrest, allowing the headrest 120 to tend to rotate towards the center of the housing 110. In one embodiment of this application, the housing 110 is generally selected as a helmet. The bone conduction microphone 600 is disposed on the headrest 120; that is, the bone conduction microphone 600 can be mounted on the headrest 120. The bone conduction microphone 200 is located on the support portion 100, and can generally be mounted on the top head support 120. The communication module is located on the support portion 100, and can generally be mounted on the top head support 120. The communication module is electrically connected to both the bone conduction pickup 600 and the bone conduction microphone 200, meaning the communication module and the bone conduction pickup 600 are connected, and the communication module and the bone conduction microphone 200 are also connected. The bone conduction pickup 600 is located above the bone conduction microphone 200. In one embodiment of this application, the bone conduction pickup 600 is used to contact the user's parietal or frontal bone, and the bone conduction microphone 200 is used to contact the user's temporal bone. The bone conduction pickup 600 is also called a bone conduction microphone, bone conduction receiver, or microphone.

[0044] The technical solution of this invention provides an elastic structure 500 at the rotational position of the head support 120 and the housing 110. The elastic structure 500 has a torsional force and is used to cause the head support 120 to tend to rotate towards the center of the housing 110, thus causing it to tend to rotate towards the user's head. When the user puts the housing 110 on their head, the user's head presses against the head support 120. The elastic structure 500 adaptively adjusts the rotation angle of the head support 120 according to the size of the user's head, thereby adjusting the contact point between the bone conduction microphone and the user's head. The technical solution of this invention can adaptively adjust the contact point according to the size of the user's head.

[0045] The technical solution of this invention employs a bone conduction microphone 600 positioned above the bone conduction amplifier 200. This allows the bone conduction microphone 600 to better cooperate with the user's parietal or frontal bone to achieve bone conduction sound transmission. Combined with a communication module, this enables the user's voice to be transmitted via bone conduction, resulting in excellent bone conduction performance. Similarly, the bone conduction amplifier 200 better cooperates with the user's temporal bone to achieve bone conduction sound transmission. Combined with a communication module, external sounds are processed by the communication module and then transmitted to the user via bone conduction, also resulting in excellent bone conduction performance. This technical solution of the invention simultaneously possesses sound pickup and playback functions, and exhibits excellent bone conduction performance.

[0046] Optionally, in one embodiment of this application, such as Figure 2 and Figure 3As shown, the head support 120 is rotatably connected to the housing 110, and the head support 120 and the housing 110 can rotate relative to each other. The head support 120 rotates relative to the housing 110 via a fixed bracket 130. The head support 120 includes a first support segment 121 located above the rotation position and a second support segment 122 located below the rotation position. The position where the head support 120 and the housing 110 achieve the rotation function is the rotation position. The first support segment 121 is located above the rotation position, and the second support segment 122 is located below the rotation position. The bone conduction pickup 600 is disposed on the first support segment 121, and the bone conduction amplifier 200 is disposed on the second support segment 122. In other words, the bone conduction pickup 600 is mounted on the first support segment 121, and the bone conduction amplifier 200 is mounted on the second support segment 122. In one embodiment of this application, the included angle between the first support segment 121 and the second support segment 122 is less than 180°. Since different users have different head sizes, the top support 120 and the housing 110 are rotatably connected, allowing the top support 120 to rotate and adapt to different user head sizes. The bone conduction pickup 600 is mounted on the first support section 121, and the bone conduction transmitter 200 is mounted on the second support section 122. This positions the bone conduction pickup 600 above the bone conduction transmitter 200, ensuring that the bone conduction pickup 600 contacts the user's parietal or frontal bone, and the bone conduction transmitter 200 contacts the user's temporal bone, thus achieving good bone conduction effect.

[0047] Optionally, in one embodiment of this application, such as Figure 3 As shown, an elastic structure 500 is provided at the rotational position of the head support 120 and the housing 110. The elastic structure 500 can be a torsion spring or the like. The elastic structure 500 is used to make the first support segment 121 tend to rotate toward the middle of the housing 110. The elastic structure 500 has a torsional force, which can make the first support segment 121 tend to rotate toward the user's head. When the user puts the housing 110 on the user's head, the user's head squeezes the first support segment 121. The elastic structure 500 can adaptively adjust the rotation angle of the first support segment 121 according to the size of the user's head.

[0048] Optionally, in one embodiment of this application, such as Figure 3 and Figure 4As shown, the head support 120 also includes a tubular body 123, and the support portion 100 includes a fixed support 130. A first support segment 121 is connected to the upper side of the tubular body 123, and a second support segment 122 is connected to the lower side of the tubular body 123. The rotational position of the head support 120 and the housing 110 is the relative rotational position of the tubular body 123 and the fixed support 130. The first support segment 121, the tubular body 123, and the second support segment 122 can be integrally formed. The tubular body 123 includes an outer tube 123a, an inner tube 123b, and a connecting plate 123c. The inner tube 123b is disposed inside the outer tube 123a, i.e., the inner tube 123b is inserted into the outer tube 123a. The connecting plate 123c is disposed between the inner tube 123b and the outer tube 123a. The connecting plate 123c is disc-shaped. The outer tube 123a, inner tube 123b, and connecting plate 123c can be integrally formed. The connecting plate 123c is provided with a first connecting hole 123d. The fixed bracket 130 is provided with a rotating shaft 130b and a second connecting hole (not shown in the figure). The first connecting hole is disposed on the connecting plate 123c. The rotating shaft 130b is inserted into the center of the inner tube 123b, i.e., inserted into the top bracket, and the rotating shaft 130b can rotate relative to the inner tube 123b. An elastic structure 500 is fitted onto the rotating shaft 130b. One end of the elastic structure 500 passes through the first connecting hole 123d and is connected to the tubular body 123. The other end of the elastic structure 500 passes through the second connecting hole and is connected to the fixed bracket 130. Optionally, the elastic structure 500 is a torsion spring, i.e., the spring body of the torsion spring is fitted onto the rotating shaft, one torsion arm of the torsion spring is connected to the top bracket, and the other torsion arm is connected to the fixed bracket. Optionally, the elastic structure is a spring, with retaining plates at both ends, i.e., two retaining plates are fixedly installed at both ends of the spring. One retaining plate of the spring is connected to the top bracket, and the other retaining plate is connected to the fixed bracket. The axis of the spring is twisted at a certain angle, i.e., the spring has a certain torsional potential energy, which causes the top bracket to have a tendency to rotate toward the middle of the shell. In some embodiments of this application, the first bracket segment 121 may also be connected to the upper side of the fixed bracket 130, and the second bracket segment 122 may be connected to the lower side of the fixed bracket 130. By setting up the tubular body 123, the fixed bracket 130, and the elastic structure 500, the relative rotation of the top bracket 120 and the shell 110 can be realized, and the top bracket 120 can have a tendency to rotate.

[0049] Optionally, in one embodiment of this application, such as Figure 3 and Figure 4As shown, the head support 120 also includes a fixing bolt (not shown in the figure), and a threaded hole (not shown in the figure) is provided on the end face of the rotating shaft 130b. The fixing bolt is inserted into the outer tube 123a and passes through the interior of the inner tube 123b to be threadedly connected to the threaded hole on the end face of the rotating shaft 130b, thereby fixing the fixing support 130 in the axial direction of the rotating shaft 130b and preventing the rotating shaft 130b from moving in the axial direction. Optionally, a wiring channel is formed inside the head support and the fixing support, and the wire of the control box passes through the wiring channel to connect to the bone conduction amplifier. In some embodiments of this application, the fixing bolt is hollow, the wire passes through the wiring channel of the fixing support, then through the hollow of the fixing bolt to enter the head support, the wire passes through the center of the inner tube, and the second support section and the shaft protrusion have wiring channels inside, through which the wire passes and connects to the bone conduction amplifier.

[0050] Optionally, in one embodiment of this application, the rotating shaft 130b is provided with an annular or conical protrusion (not shown in the figure). The diameter of the protrusion is larger than the inner diameter of the inner tube 123b. The protrusion has a certain elasticity. After the rotating shaft 130b passes through the inner tube 123b, the protrusion also deforms and passes through the inner tube 123b. After the protrusion completely passes through the inner tube 123b, the protrusion returns to its original shape. The protrusion abuts against the end face of the inner tube 123b, thereby fixing the fixed bracket 130 in the axial direction of the rotating shaft 130b and preventing the rotating shaft 130b from moving in the axial direction.

[0051] Optionally, in one embodiment of this application, such as Figure 4 As shown, the first support segment 121 has a mounting groove 125 on its inner side. Here, "inner side" refers to the side of the first support segment 121 facing the user's head. The bone conduction microphone 600 is disposed within the mounting groove 125, and the groove opening of the mounting groove 125 is covered with a soft rubber portion 126. That is, a mounting groove 125 is formed on the first support segment 121, the bone conduction microphone 600 is placed within the mounting groove 125, and the mounting groove 125 is covered with the soft rubber portion 126. The bone conduction microphone 600 abuts against the user's parietal or frontal bone through the soft rubber portion 126, and sound transmission via bone conduction is achieved through the bone conduction microphone 600 and the soft rubber portion 126. The first support segment 121 has a hollow structure, which can reduce the weight of the overall head support 120.

[0052] Optionally, in one embodiment of this application, such as Figure 3As shown, the bone conduction amplifier 200 includes a rocker arm 210 and a vibrator 220. One end of the rocker arm 210 is rotatably connected to the second support segment 122, meaning that one end of the rocker arm 210 can rotate relative to the second support segment 122. The vibrator 220 is located at the other end of the rocker arm 210. The rocker arm 210 can rotate relative to the second support segment 122, thereby adjusting the contact point between the vibrator 220 and the user's head. This method of moving the rocker arm 210 is convenient to operate and allows the user to easily adjust the optimal contact point between the vibrator 220 and the head, thus achieving a good bone conduction effect.

[0053] Optionally, in one embodiment of this application, such as Figure 3 As shown, the second support segment 122 is provided with a shaft protrusion 124, which may be cylindrical and can be integrally formed with the second support segment 122. The shaft protrusion 124 is provided with a limiting protrusion 243, and the rocker arm 210 is provided with a rotating groove 211 corresponding to the shaft protrusion 124. That is, a rotating groove 211 is provided at a corresponding position on the rocker arm 210, and the rocker arm 210 covers the shaft protrusion 124 through the rotating groove 211. The rotating groove 211 is provided with multiple limiting grooves 212 spaced circumferentially. The multiple limiting grooves 212 are evenly distributed along the circumferential direction, and the limiting protrusion 243 can switch between the multiple limiting grooves 212, that is, the limiting protrusion 243 can rotate from one limiting groove 212 to another. As the rocker arm 210 is moved, the limiting protrusion 243 switches between multiple limiting grooves 212, thereby achieving a fixed position of the rocker arm 210, which facilitates the user to adjust the optimal contact point between the vibrator 220 and the head. In some embodiments of this application, the limiting grooves 212 are arc-shaped, which facilitates the switching of the limiting protrusion 243 within multiple limiting grooves 212.

[0054] Optionally, in one embodiment of this application, such as Figure 3 and Figure 5 As shown, the shaft protrusion 124 is provided with a spring piece 240, and the limiting protrusion 243 is formed on the spring piece 240. In other words, the limiting protrusion 243 is provided on the spring piece 240. The limiting protrusion 243 also has a certain elasticity, which facilitates switching between multiple limiting grooves 212.

[0055] Optionally, in one embodiment of this application, such as Figure 3 and Figure 6As shown, the spring piece 240 includes an arc-shaped portion 242 and two insertion portions 241 located at both ends of the arc-shaped portion 242. The limiting protrusion 243 is disposed on the arc-shaped portion 242. The two insertion portions 241 are respectively located at both ends of the arc-shaped portion 242 and are perpendicular to the arc-shaped portion 242. The shaft protrusion 124 is provided with two slots, and the two insertion portions 241 are respectively inserted into the two slots. By providing the insertion portions 241 and slots, the spring piece 240 can be fixed on the shaft protrusion 124.

[0056] Optionally, in one embodiment of this application, such as Figure 3 As shown, the other end of the rocker arm 210 is also provided with a bone conduction housing 230, and the vibrator 220 is installed inside the bone conduction housing 230. In other words, the vibrator 220 is installed between the rocker arm 210 and the bone conduction housing 230. The bone conduction amplifier 200 abuts against the user's temporal bone through the bone conduction housing 230, and bone conduction sound transmission is achieved through the bone conduction amplifier 200 and the bone conduction housing 230.

[0057] Optionally, in one embodiment of this application, such as Figure 2 As shown, the bone conduction communication component also includes a control box 300 and a spotlight box 400. The control box 300 is located on the support portion 100 and can generally be mounted on the fixed bracket 130. The communication module is located within the control box 300, and can be a wireless communication module, such as, but not limited to, Bluetooth or WiFi. The control box 300 has control buttons for functions such as volume up / down, play / pause, skip tracks, and answering / hanging up calls. The spotlight box 400 is located on the support portion 100 and can generally be mounted on the fixed bracket 130. The spotlight box 400 can be an LED box and has an LED spotlight and LED control buttons for controlling the LED spotlight's on / off state. The spotlight box 400 and the control box 300 can be manufactured as a single, integrated unit. The control box 300 and the spotlight box are provided with hanging slots, and the fixed bracket 130 is provided with a hook 130a. That is, the fixed bracket 130 is provided with a hook 130a, and the control box 300 and the spotlight box are installed on the fixed bracket 130 through the hook-and-loop engagement of the hanging slots and the hook 130a. In some embodiments of this application, two headrests 120 are symmetrically installed on both sides of the housing 110. Correspondingly, the control box 300 is installed on one headrest 120, and the spotlight box 400 is installed on the other headrest 120. There can also be two bone conduction pickups 600 and bone conduction amplifiers 200, each symmetrically installed on a headrest 120.

[0058] Optionally, in one embodiment of this application, the bone conduction communication component is a helmet-mounted bone conduction headset. The housing 110 can be a helmet or similar device. When the housing 110 is set as a helmet, a clearance (not shown in the figure) should be provided inside the helmet at the position corresponding to the top support 120, to ensure that the first support segment 121 does not contact the helmet when it rotates. This can prevent sound transmitted from the helmet (such as the sound produced by knocking on the helmet) from affecting the sound propagation of the bone conduction pickup 600 and the bone conduction amplifier 200. The helmet can be worn on the user's head, and the bone conduction headset can be installed on the helmet to achieve sound pickup and playback functions, and has a good bone conduction effect.

[0059] Optionally, in one embodiment of this application, the fixing bracket 130 is fixed to the helmet by bolts, that is, the fixing bracket 130 and the helmet are fixed together with bolts, thereby connecting the bracket part 100 to the helmet. In some embodiments of this application, such as Figure 7 As shown, the fixing bracket 130 is fixed to the helmet by clips. In some embodiments of this application, the fixing bracket 130 is provided with a first clamping block 130c and a second clamping block 130e. The first clamping block 130c, the second clamping block 130e and the fixing bracket 130 can be integrally formed. The first clamping block 130c and the second clamping block 130e can also be fixed to the fixing bracket 130 by other means. In the figures, the first clamping block 130c, the second clamping block 130e and the fixing bracket 130 are drawn separately.
