Technical Field

[0001] This application relates to the field of headphone technology, specifically to a bone conduction headphone and headphone set. Background Technology

[0002] Headphones allow people to listen to audio information from electronic devices, such as music, radio broadcasts, and voice messages, without disturbing others. Currently, various types of headphones are available on the market, including bone conduction headphones. Bone conduction headphones convert sound information into mechanical vibrations and transmit the sound information through the skull. These headphones reduce damage to the eardrum and ear canal and are suitable for people with hearing impairments, making them widely used in today's society.

[0003] The inventors of this application have discovered that existing bone conduction headphones suffer from problems such as poor fixation and difficulty in adjusting the wearing position, which seriously affect the user experience. Summary of the Invention

[0004] In view of the above problems, this application provides a bone conduction headphone and headphone set, which can effectively improve the fixation effect of bone conduction headphones and make it easier to adjust the wearing position.

[0005] According to one aspect of the embodiments of this application, a bone conduction headphone is provided. The bone conduction headphone includes a hook portion for hanging on a human ear; one end of the hook portion is connected to an abutment portion, the abutment portion being angled to the hook portion, and one end of the abutment portion being used to abut against the inside of the human ear; a plug portion is provided extending from the side of the abutment portion toward the inside of the human ear, the plug portion being angled to the other end of the abutment portion, the plug portion being used together with the other end of the abutment portion to clamp the tragus of the human ear; a fitting portion is provided extending from the end of the abutment portion away from the hook portion, the fitting portion having a vibration structure disposed therein, the fitting portion being used to fit against the human body and output sound information through the vibration structure.

[0006] In the technical solution of this application embodiment, by hanging the hook part on the human ear, one end of the abutting part abuts against the inside of the human ear, while the other end of the abutting part and the plug part together form a clamping effect on the tragus of the human ear, so that the fitting part is firmly attached to the human body and outputs sound information, achieving a better fixation effect, while also having good wearing comfort.

[0007] In some embodiments, the mounting portion includes a mounting structure and an adjustment structure connected to one end of the mounting structure, the end of the adjustment structure away from the mounting structure being connected to the abutment portion; the adjustment structure is made of a material with memory function and is used to adjust the relative position of the mounting structure and the abutment portion. The adjustment structure made of a material with memory function allows for more convenient adjustment of the wearing position of the bone conduction headphones.

[0008] In some embodiments, the angle between the abutting portion and the fitting portion is adjustable. This adjustable angle allows for position adjustment of the fitting portion, improving the fitting effect and thus ensuring good sound quality.

[0009] In some embodiments, a cushioning pad is provided on the side of the fitting portion that contacts the human body. By providing a cushioning pad, the tactile feel of the fitting portion can be improved, thereby enhancing the user experience.

[0010] In some embodiments, the abutment portion is detachably connected to the plug portion.

Through the above embodiments, the amplification unit can amplify the sound signal received by the pickup unit, making the sound output clearer and more suitable for hearing-impaired people; in addition, placing the pickup unit within the mounting structure, away from the vibrating structure, can effectively avoid the feedback problem caused by amplified sound signals.

[0013] In some embodiments, an antenna is also provided at one end of the circuit board near the free end of the mounting structure. The antenna is used to receive and transmit radio wave signals. Because the circuit board is located inside the mounting structure, the antenna on the circuit board can fully contact the external environment, thereby receiving and transmitting radio wave signals more effectively.

[0014] In some embodiments, one end of the hook structure connected to the adjustment structure is recessed inward to form a first connecting groove, through which the adjustment structure is inserted into the hook structure; the other end of the abutment portion connected to the adjustment structure is recessed inward to form a second connecting groove, through which the adjustment structure is inserted into the abutment portion. Inserting the adjustment structure into the connecting groove facilitates the positioning and installation of the adjustment structure, reducing assembly difficulty.

[0015] In some embodiments, a first snap-fit ​​portion is further provided in the first connecting groove, and a second snap-fit ​​portion is provided on the adjusting structure at a position corresponding to the first snap-fit ​​portion. One end of the adjusting structure is inserted into the first connecting groove and snapped into the first connecting groove by the second snap-fit ​​portion and the first snap-fit ​​portion; and / or, a first through hole is provided in the second connecting groove, and a second through hole is provided on the adjusting structure at a position corresponding to the first through hole.

[0041] Headphones allow people to listen to audio information from electronic devices, such as music, radio broadcasts, and voice messages, without disturbing others. Currently, various types of headphones are available on the market, including bone conduction headphones. Bone conduction headphones convert sound information into mechanical vibrations. By fitting the headphones tightly against the body's bones, the vibrational sound information is transmitted directly to the auditory nerve through the bones. Therefore, these headphones do not need to be inserted into the ear, reducing damage to the eardrum and ear canal. Thus, improvements to bone conduction headphones are of great significance.

[0042] The inventors of this application discovered that, to improve the performance of bone conduction headphones, the headphone's vibration unit needs to be in close contact with the human body. Most existing bone conduction headphones connect the left and right earpieces via a connecting bridge, requiring both earpieces to be worn simultaneously. The connecting bridge clamps and fixes the two earpieces to the skull for optimal contact. This type of bone conduction headphone has a complex structure and is relatively large. While the connecting bridge can clamp and fix the two earpieces to the skull, prolonged clamping can cause head discomfort and, in severe cases, may lead to head problems. Furthermore, because the two earpieces are fixed by the connecting bridge, adjusting the wearing position is difficult and cannot meet the needs of using a single earpiece. While some bone conduction headphones use a separate left and right earpiece design, hanging and fixing the left and right earpieces separately to avoid discomfort caused by the connecting bridge, these headphones are not very secure during use, easily loosening and falling off, and often resulting in poor contact between the earpieces and the body, leading to poor sound transmission quality.

[0043] To address the aforementioned problems, the inventors of this application have designed a bone conduction headphone. The bone conduction headphone mainly includes a hook part, a contact part, a plug part, and a fitting part. On one hand, the hook part hangs the headphone on the ear to prevent it from falling off. Simultaneously, the contact part and the plug part are connected and positioned at a certain angle. During use, one end of the contact part abuts against the side wall of the concha, and the plug part is inserted into the ear and abuts against the inner side of the tragus. The other end of the contact part and the plug part together create a clamping effect on the ear, thus ensuring a stable fit between the fitting part and the body. This design allows the bone conduction headphone to be more securely fixed to the ear, preventing it from easily falling off. On the other hand, it allows for a more complete fit between the fitting part and the body. The vibration structure within the fitting part can better transmit sound information. Furthermore, the design of the plug part reduces the contact area between the plug and the body, thereby reducing the user's foreign body sensation and providing excellent wearing comfort. Meanwhile, to facilitate user adjustment of the wearing position and ensure a better fit between the fitting part and the body, the hook-on part also includes an adjustment structure. This adjustment structure is made of a material with memory function, allowing for easier adjustment of the bone conduction headphones' wearing position through the material properties of the adjustment structure. The fitting part and the abutment part can also be configured with an adjustable angle connection, allowing for adjustment of their positional relationship according to the body's structure to form an appropriate angle, thus ensuring a better fit between the fitting part and the body.

[0044] The bone conduction headphones disclosed in this application are applicable to all application scenarios of headphones and can also be used as hearing aids for people with hearing impairments.

[0045] According to the embodiments of this application, please refer to Figures 1 to 4 The bone conduction headphones 1000 include a hook part 100 for hanging on a person's ear; one end of the hook part 100 is connected to an abutment part 200, which is angled to the hook part 100 and abuts against the inside of the ear; a plug part 300 extends from the abutment part 200 toward the inside of the ear, which is angled to the abutment part 200 and abuts against the tragus; and a fitting part 400 extends from the abutment part 200 away from the hook part 100, which contains a vibration structure 401 and is fitted to fit against the body and output sound information through the vibration structure 401.

[0046] The hanging part 100 is attached to the ear when the bone conduction headphones 1000 are used. Preferably, the hanging part 100 can be attached to the back of the auricle to provide support and prevent the bone conduction headphones 1000 from falling off. Figure 1As shown, the shape of the hanging part 100 can be designed with reference to the contour of the human ear, so that the hanging part 100 has a certain arc. It can also be appropriately counterweighted at the end of the hanging part to make the center of gravity of the hanging part 100 more stable, so as to provide a more comfortable user experience.

[0047] The abutment portion 200 is connected to one end of the hook portion 100 and is set at a certain angle to the hook portion 100. Specifically, this "certain angle" refers to the angle between the body of the abutment portion 200 and the end of the hook portion 100 connected to the abutment portion 200, to adapt to the structure of the human ear. This allows the abutment portion 200 to be placed at the optimal angle inside the ear when the bone conduction headphones 1000 are used. Preferably, the abutment portion 200 can be placed inside the concha of the ear, with one end of the abutment portion 200 abutting against the inner wall of the concha, thus providing support for the abutment portion 200. The shape of the abutment portion 200 and the relative angle between the abutment portion 200 and the hook portion 100 can be designed considering factors such as comfort and secure fixation. The volume of the abutment portion 200 should be minimized while meeting usage requirements; if the volume is too large, it may block the ear canal, causing ear stuffiness and discomfort.

[0048] The plug portion 300 is connected to the abutment portion 200 and extends towards the inside of the ear when the bone conduction headphones 1000 are in use. Preferably, the plug portion 300 can extend towards the inside of the tragus of the ear and abut against the tragus, so that the plug portion 300 receives support from the tragus. Figure 3 As shown, the other end of the plug portion 300 and the abutment portion 200 are set at a certain angle α, which is preferably less than 90 degrees. This allows the plug portion 300 and the abutment portion 200 to work together to clamp the tragus of the ear, improving the fixation effect of the bone conduction headphones 1000. It should be noted that the plug portion 300 does not need to block the ear canal during use; instead, it rests against the user's tragus. Compared to traditional in-ear headphones, this design avoids ear canal blockage during prolonged use, preventing ear stuffiness and discomfort, and also prevents safety hazards caused by not being able to hear external sounds when used outdoors. To improve the user experience, the plug portion 300 is preferably made of a flexible material, such as silicone or TPE, to avoid excessive pressure on the ear from overly rigid materials. In addition, the plug 300 can be designed in a concave arc shape, such as making the side of the plug 300 facing the inside of the tragus concave, so that the side facing the inside of the tragus does not completely fit the skin of the tragus, and only a small part of the end contacts the tragus. This design reduces the contact area, which can reduce the user's foreign body sensation and increase wearing comfort.

[0049] The fitting portion 400 is located at the end of the abutment portion 200 away from the hook portion 100. When the bone conduction headphones 1000 are in use, the fitting portion 400 fits against the human body. Preferably, the fitting portion 400 can fit against the skin surface corresponding to the position of the human skull. Figure 2 As shown, a vibration structure 401 is provided within the fitting part 400, which can convert sound into mechanical vibration. When the fitting part 400 is in contact with the human body, the sound information in the form of vibration is transmitted using the principle of bone conduction, allowing the person to hear the sound. To ensure a more complete fit between the fitting part 400 and the human body, the fitting part 400 can be set at a certain angle relative to the abutment part 200. Alternatively, the position where the fitting part 400 is in contact with the human body can be designed as an appropriate curved surface to increase the contact area, thereby improving the quality of sound output and enhancing the user experience.

[0050] When using the bone conduction headphones 1000, taking the right ear as an example, as follows... Figure 4 As shown, with the user's face facing the direction of the arrow, the hook part 100 is hung on the back of the auricle of the right ear, making contact at and around position P1 in the diagram; the abutment part 200 is placed into the concha of the right ear, making contact with the inner side of the concha at and around position P2 in the diagram; the plug part 300 is inserted into the inner side of the tragus of the right ear, making contact with the inner side of the tragus at and around position P3 in the diagram, and together with the abutment part 200, it clamps the tragus; the fitting part 400 is fitted against the user's face at and around position P4 in the diagram. Through the above operations, the bone conduction headphones 1000 are worn in the right ear. The support provided by positions P1, P2, and P3 and their vicinity ensures the stability of the fitting part 400 at position P4 in the diagram, and allows the bone conduction headphones 1000 to be securely fixed in the right ear, preventing it from easily falling off. The wearing operation for the left ear is the same.

[0051] Through the above embodiments, the bone conduction headphones 1000 form a multi-point fixed support with the human ear through the hook part 100, the abutment part 200 and the plug part 300, which ensures the stability of the fit part 400 in fit with the human body, so that the bone conduction headphones 1000 has a more stable fixation effect, and also has good wearing comfort.

[0052] To facilitate adjustment of the wearing position, in some embodiments, optionally, please continue to refer to Figure 1 The mounting part 100 includes a mounting structure 110 and an adjustment structure 120 connected to one end of the mounting structure 110. The end of the adjustment structure 120 away from the mounting structure 110 is connected to the abutment part 200. The adjustment structure 120 is made of a material with memory function and is used to adjust the relative position of the mounting structure 110 and the abutment part 200.

[0053] The hook structure 110 is the structure in the hook part 100 that contacts and supports the human ear. The two ends of the adjustment structure 120 are connected to the hook structure 110 and the abutment part 200 respectively, and are used to adjust the relative position of the hook structure 110 and the abutment part 200 so that the wearing comfort can be adjusted to achieve the optimal state. The adjustment structure 120 is made of a material with memory function, such as copper-titanium alloy or copper-zinc alloy, which allows the adjustment structure 120 to maintain any shape without springing back, thus avoiding the need for repeated adjustments. Due to the characteristics of the material, the adjustment structure 120 can have a large adjustment range and requires less force to adjust, greatly improving the convenience of adjustment; in addition, the adjustment structure 120 does not show obvious bending marks when bent, maintaining its overall aesthetic appearance.

[0054] Through the above embodiments, the bone conduction headphones 1000 can be adjusted and maintained in any position during wear to achieve optimal wearing comfort.

[0055] To further facilitate adjustment of the wearing position and ensure a closer fit between the fitting part and the head, thus guaranteeing the effectiveness of the bone conduction headphones, in some embodiments, optionally, please continue to refer to... Figure 1 The angle between the contact portion 200 and the fitting portion 400 can be adjusted.

[0056] Because the surface of the human head has a certain curvature, and the bone conduction headphones 1000 need to fit the vibration structure 401 tightly against the human head to achieve optimal sound output quality, this embodiment of the application sets the connection between the abutment portion 200 and the fitting portion 400 to an adjustable angle to facilitate adjustment of the fit between the fitting portion 400 and the head, in order to accommodate the differences in head shapes among different users. Specifically, as... Figure 1 As shown in the diagram, part A is the connection between the abutment part 200 and the fitting part 400. This part can be made of a material with memory function, such as a nickel-titanium alloy or a copper-zinc alloy, so that the relative position between the abutment part 200 and the fitting part 400 can be flexibly adjusted and maintained in any relative position within the adjustment range. In addition, the connection between the abutment part 200 and the fitting part 400 can also be a snap-fit ​​connection with multiple locking positions, or a hinged connection using coiled pins. These methods allow adjustment of the angle between the abutment part 200 and the fitting part 400 facing the human body, thereby adjusting the degree of fit between the fitting part 400 and the head, achieving an adjustable connection.

[0057] Through the above embodiments, the bone conduction headphones 1000 can more conveniently adjust the fit between the fitting part 400 and the human body during use, so as to achieve the best wearing comfort.

[0058] To improve the user experience, in some embodiments, optionally, please continue reading. Figure 1 A cushioning pad 402 is provided on the side of the fitting part 400 that fits against the human body.

[0059] Preferably, the cushioning pad 402 can be made of a skin-friendly flexible material, such as silicone, to improve the feel of the contact portion 400 and make the contact portion 400 more comfortable when it is in contact with the human body; the cushioning pad 402 can also contact the vibrating structure 401 to eliminate vibration noise and improve the quality of the output sound.

[0060] Through the above embodiments, the cushioning pad 402 can improve the tactile feel of the fitting part 400 against the human body and eliminate the vibration noise of the vibration structure 401, thereby improving the sound quality and improving the user experience of the bone conduction headphones 1000.

[0061] To improve assembly flexibility and further enhance the user experience, in some embodiments, optionally, please continue to refer to... Figure 1 The abutment part 200 and the plug part 300 are detachably connected.

[0062] Considering the variability in ear structure, the abutment 200 and / or the plug 300 need to be customized to meet different usage requirements. However, changing the abutment 200 is extremely inconvenient in practice and may affect the assembly effect with other parts. Therefore, prioritizing customization of the plug 300 can reduce customization costs. On the other hand, by making the plug 300 a detachable connection, it can be replaced at any time, improving assembly flexibility and meeting different usage needs. Specifically, the plug 300 can be made into structures of different lengths, radii, and shapes. During use, users can replace different plugs 300 according to their own conditions to adapt to different ear structures, improving the product's applicability. Moreover, with the increase in usage time, the plug 300 is prone to bacterial growth and dirt accumulation. By making it a replaceable structure, hygiene can be ensured. As an example, in this embodiment, the plug portion 300 and the abutment portion 200 are connected by an internally threaded cylindrical pin. Specifically, the internally threaded cylindrical pin is fixed in the abutment portion 200 by a screw and extends towards the plug portion 300. A pin hole is provided at a corresponding position in the plug portion 300, and the extended end of the internally threaded cylindrical pin is inserted through this pin hole, thereby achieving the connection between the plug portion 300 and the abutment portion 200. Alternatively, the plug portion 300 and the abutment portion 200 can also be detachably connected by other methods such as snap-fit.

[0063] Through the above embodiments, the detachable connection between the abutment part 200 and the plug part 300 improves the flexibility of assembly, realizes personalized customization to meet different usage needs, reduces customization costs, and improves the user experience.

[0064] To make better use of space, reduce the volume and weight of the contact portion 200, and further improve wearing comfort, in some embodiments, optionally, please continue to refer to Figure 2 A circuit board 111 is provided inside the mounting structure 110, and a battery 201 is provided inside the abutment part 200. The battery 201 is electrically connected to the circuit board 111 via a cable 121, which is located inside the adjustment structure 120.

[0065] Considering that the hanging structure 110 is a structure that hangs on the ear, while the abutment part 200 is a structure that enters the ear, the size of the hanging structure 110 is often larger than that of the abutment part 200 during the design process. Therefore, the larger circuit board 111 can be placed inside the hanging structure 110, the smaller battery 201 can be placed inside the abutment part 200, and the cable 121, which serves as a connection, can be placed inside the adjustment structure 120. This design can reduce the size and weight of the abutment part 200, avoiding discomfort such as blockage or pressure on the user's ear caused by an excessively large or heavy abutment part 200.

[0066] Through the above embodiments, the internal space of the hanging structure 110, the adjustment structure 120 and the abutment part 200 is reasonably utilized, and an optimal layout scheme is provided for the circuit components, which minimizes the volume and weight of the abutment part 200 and further improves wearing comfort.

[0067] To achieve clearer sound output, make the bone conduction headphones 1000 suitable for hearing-impaired individuals, and avoid feedback issues, in some embodiments, optionally, please refer to [further details omitted]. Figure 2 The mounting structure 110 is also equipped with a pickup unit 112, which is used to pick up sound signals from the external environment. The circuit board 111 is also equipped with an amplification unit 113, which is electrically connected to the pickup unit 112 and to the vibration structure 401. The amplification unit 113 is used to amplify the sound signal picked up by the pickup unit 112 and output the amplified sound signal through the vibration structure 401.

[0068] The pickup unit 112 is an audio input device, which can be any type of microphone, designed specifically according to factors such as usage scenario or cost. The pickup unit 112 can be placed anywhere within the mounting structure 110; to make full use of space, it is preferably placed at the end of the circuit board 111, for example... Figure 2 The location shown.

[0069] The amplification unit 113 is a key component that allows the bone conduction headphones 1000 to be used as a hearing aid. It amplifies the sound signal received by the pickup unit 112, enabling users with hearing impairments to hear clear sound signals. When the bone conduction headphones 1000 are used as a hearing aid, the amplification unit 113 is required to provide hearing aid effects. The amplification unit 113 enhances the sound signal received by the pickup unit 112, making the sound output clearer, thus making the bone conduction headphones 1000 suitable for people with hearing impairments.

[0070] For hearing aids, since the sound signal received by the pickup unit needs to be amplified and then output through the output unit, if the pickup unit and output unit of the hearing aid are not set properly, the output sound can easily be received by the pickup unit and amplified again, which can cause self-oscillation and affect the use of the hearing aid.

[0071] The bone conduction headphones 1000 proposed in this application also suffer from the same problem. If the sound signal output from the vibration structure 401 is received by the pickup unit 112 and amplified by the amplification unit 113 before being output again, the sound signal is easily amplified and output repeatedly, resulting in feedback, which seriously affects the user experience and may even damage the user's hearing. If the pickup unit 112 is placed near the vibration structure 401, that is, near the contact portion 400, self-excitation is likely to occur, generating feedback. If the pickup unit 112 is placed inside the contact portion 200, since the contact portion 200 is closer to the ear canal, the impact on the ear is greater when feedback occurs; moreover, the contact portion 200 is closer to the contact portion 400 than the hook portion 100, so self-excitation is also likely to occur if the pickup unit 112 is placed in the contact portion 200.

[0072] In view of this, in this embodiment of the application, the pickup unit 112 is disposed in the mounting structure 110 of the mounting part 100, so that it is as far away from the vibration structure 401 as possible. Moreover, the mounting part 100 is disposed on the back of the auricle, and during use, it and the fitting part 400 are respectively located on the front and back sides of the user's ear, which can better avoid interference between the two and effectively avoid the howling problem caused by repeatedly amplifying the sound signal.

[0073] To more effectively receive and transmit radio wave signals and improve signal stability, in some embodiments, optionally, please continue to refer to... Figure 2 An antenna 114 is also provided on one end of the circuit board 111 near the free end of the mounting structure 110. The antenna 114 is used to receive and transmit radio wave signals.

[0074] Antenna 114 is a crucial component for the bone conduction headphones 1000 to achieve Bluetooth wireless connectivity, and its signal reception performance affects the stability of the wireless connection. If antenna 114 is placed inside the abutment portion 200, since the abutment portion 200 partially enters the ear during use, it will be blocked by the ear, weakening the wireless signal and thus affecting the transmission effect. In the above embodiment, antenna 114 is located near the free end of the hanging structure 110, so that when the bone conduction headphones 1000 are in use, antenna 114 is located behind the user's auricle, with its end also facing backward. Compared to placing it in other locations, this design allows for more complete contact with the external environment, thereby more effectively receiving and transmitting radio wave signals and maximizing signal stability.

[0075] To further improve space utilization, in some embodiments, optionally, please refer to Figure 1 and Figure 2 A function button 115 is provided on the mounting structure 110 at a position corresponding to the circuit board 111, and the function button 115 abuts against the circuit board 111; a charging interface 202 is provided on the abutting part 200, and the charging interface 202 is electrically connected to the battery 201 and used to charge the battery 201.

[0076] Specifically, such as Figure 2 As shown, function button 115 is used to implement some specified functions of the bone conduction headphones 1000, such as device pairing and reset. Function button 115 is correspondingly set with circuit board 111 and abuts against circuit board 111 along direction B in the figure, so that function button 115 can touch circuit board 111 when pressed, thereby triggering the specified function. Charging interface 202 is used to charge battery 201 to meet the usage and battery life requirements of bone conduction headphones 1000. In this embodiment, the charging interface 202 is preferably in the form of a spring pin, which can effectively prevent external dust and debris from entering the abutment part 200 through the charging interface 202 and affecting the performance. In addition, the charging interface 202 can also be other interface forms, such as Type-C interface, magnetic interface, etc.

[0077] Through the above embodiments, the function button 115 and the charging interface 202 are set close to the positions of the circuit board 111 and the battery 201, respectively, which can make the structure more compact and improve the space utilization.

[0078] To reduce assembly difficulty, in some embodiments, optionally, please refer to [reference needed]. Figure 5The end of the hook structure 110 that is connected to the adjustment structure 120 (hidden in the figure) is recessed inward to form a first connecting groove 11, and the adjustment structure 120 is inserted into the hook structure 110 through the first connecting groove 11; the end of the abutment part 200 that is connected to the adjustment structure 120 is recessed inward to form a second connecting groove 20, and the adjustment structure 120 is inserted into the abutment part 200 through the second connecting groove 20.

[0079] The first connecting groove 11 and the second connecting groove 20 are used for assembling and positioning the adjustment structure 120. Therefore, the shapes of the first connecting groove 11 and the second connecting groove 20 should be determined according to the interface shapes at both ends of the adjustment structure 120. When the adjustment structure 120 is inserted into the first connecting groove 11 and the second connecting groove 20, the matching interface shapes achieve a positioning function, which helps the adjustment structure 120 to be installed and fixed in the correct position.

[0080] The above embodiments, by providing the first connecting groove 11 and the second connecting groove 20, facilitate the positioning and installation of the adjustment structure 120, thereby reducing the difficulty of assembly.

[0081] To further improve assembly flexibility, in some embodiments, optionally, please refer to... Figure 2 and Figure 5 The first connecting groove 11 is also provided with a first snap-fit ​​part 11a, and the adjustment structure 120 is provided with a second snap-fit ​​part 12a at a position corresponding to the first snap-fit ​​part 11a. One end of the adjustment structure 120 is inserted into the first connecting groove 11 and snaps into the first connecting groove 11 through the second snap-fit ​​part 12a; and / or, the second connecting groove 20 is provided with a first through hole 20b, and the adjustment structure 120 is provided with a second through hole 12b at a position corresponding to the first through hole 20b. One end of the adjustment structure 120 is inserted into the second connecting groove 20 and is connected to the second connecting groove 20 through a pin passing through the first through hole 20b and the second through hole 12b.

[0082] in, Figure 5 The positions of the first snap-fit ​​portion 11a and the first through hole 20b are shown. Figure 2The positions of the second snap-fit ​​portion 12a and the second through hole 12b are shown. The purpose of the above embodiment is to achieve a detachable connection of the adjustment structure 120 and to provide a preferred solution, namely, the adjustment structure 120 snaps into the first connecting groove 11 on the hanging structure 110 and is connected to the second connecting groove 20 on the abutment portion 200 by a pin. Although snap-fit ​​connections are generally superior to pin connections in detachable connection methods, snap-fit ​​connections occupy a larger volume. In this embodiment, considering that the space of the first connecting groove 11 is sufficient, a snap-fit ​​structure can be added, while the space of the second connecting groove 20 is smaller, so a through hole is opened and a pin is used for connection, balancing the factors of connection effect and volume occupation. In actual production, when the space of the second connecting groove 20 is sufficient, a snap-fit ​​structure can also be used. In addition, other detachable installation methods can also be selected.

[0083] Through the above embodiments, detachable installation is achieved between the hanging structure 110 and the adjusting structure 120, and between the adjusting structure 120 and the abutment part 200, which increases the flexibility of assembly and facilitates later replacement or maintenance.

[0084] This application also provides an earphone set, including the bone conduction earphone 1000 described in the above embodiments and a charging case. The charging case is used to store the bone conduction earphone 1000 and charge it. This earphone set is portable, making the bone conduction earphone 1000 easy to store and carry, and has a portable charging function to ensure the battery life of the bone conduction earphone 1000.
