Headphones may allow people to listen to sound information, such as music, radio stations, voice messages, etc., output by electronic devices without affecting others. There are many forms of headphones on the market today, including bone conduction headphones. The bone conduction earphone can convert sound information into mechanical vibration, and the earphone is clung to human bones to directly transmit the sound information in a vibration form to auditory nerves through the bones, so that the earphone can be used without being in the ear, and the damage to eardrum and auditory canal is reduced. Therefore, improvement of the bone conduction headset is of great significance.

According to the research, the inventor finds that in order to improve the using effect of the bone conduction earphone, the vibration unit of the earphone needs to be clung to a human body, the left and right earphone units of the existing majority of bone conduction earphone are connected through the connecting bridge, the two earphone units need to be worn and used simultaneously when in use, and the two earphone units are clamped and fixed on the skull part of the human body through the connecting bridge so as to achieve the best effect of contacting with the human body. The bone conduction earphone has a complex structure and a large volume, and although the two earphone single clips can be fastened on the skull of a human body through the connecting bridge, the long-time clamping of the human body can cause head discomfort, and head diseases can be caused when the bone conduction earphone is serious. Meanwhile, as the two earphone monomers are fixed through the connecting bridge, when the earphone is used, the wearing position is difficult to adjust, and the requirement of using a single earphone cannot be met. While some of the bone conduction headphones adopt a mode of separating left and right headphones, the left and right headphones are worn at the left and right ears respectively, so that the problem that the connecting bridge is uncomfortable to the head of a human body can be solved, but the problem that the wearing position of the headphones is difficult to adjust still exists when the headphones are used, the adjusted position is difficult to keep, the vibrating unit of the headphones is difficult to continuously and stably attach to the human body when the headphones are continuously used, the sound output quality is unstable, and the use experience of the bone conduction headphones is seriously affected.

In order to solve the problems, the inventor designs a bone conduction earphone which mainly comprises a hanging part, an abutting part and a fitting part, wherein the earphone is hung on a human ear through the hanging part, and the abutting part abuts against the inner side of the human ear, so that the earphone is prevented from falling off; meanwhile, the abutting part is hinged with the abutting part through a rolling pin, and the rolling pin forms interference fit, so that the relative included angle between the abutting part and one side of the abutting part, facing to a human body, can be adjusted. According to the bone conduction earphone, on one hand, the characteristic of hinging is utilized, the included angle between the attaching part and the abutting part can be adjusted, the attaching effect of the attaching part and a human body can be optimal through adjusting actions, at the moment, sound information is output through the vibration structure, and the optimal sound output quality can be ensured; on the other hand still utilized the interference fit that the roll round pin formed and roll round pin self elasticity, made roll round pin to have continuous extrusion force and frictional force to articulated department, and then made laminating portion with the contained angle of butt portion can keep unchanged after adjusting, makes laminating portion can laminate with the human body is continuous steadily, through setting up the vibrating structure in laminating portion, can transmit high-quality sound information steadily.

The bone conduction earphone disclosed by the embodiment of the application is suitable for all application scenes of the earphone, and can also be used as a hearing aid for people with hearing impairment.

Referring to fig. 1 to 4, according to an embodiment of the present application, a bone conduction headset 1000 includes a hooking portion 100, an abutting portion 200, and a fitting portion 300; the hanging part 100 is used for hanging on the ear; one end of the abutting part 200 is connected with one end of the hanging part 100 and is arranged at an angle, and the abutting part 200 is used for abutting against the inner side of the human ear; the other end of the abutting portion 200 is provided with a first hinge hole 210; a second hinge hole 310 is formed at one end of the attaching part 300, and the second hinge hole 310 is coaxially disposed with the first hinge hole 210 and is connected through a roll pin 400; the rolling pin 400 forms interference fit with the first hinge hole 210 and the second hinge hole 310, so that the relative included angle between the abutting part 200 and the fitting part 300 facing to one side of a human body can be adjusted; the attaching part 300 is provided therein with a vibration structure 320, and the attaching part 300 is used for attaching to a human body and outputting sound information through the vibration structure 320.

The hooking portion 100 is hung on the ear when the bone conduction earphone 1000 is in use, preferably, the hooking portion 100 can be hung on the back of the auricle, so that the hooking portion 100 is supported by the ear, and the bone conduction earphone 1000 is prevented from falling. As shown in fig. 1, the shape of the hitching part 100 can be designed according to the outline of the ear, so that the hitching part 100 has a certain arc shape, and the weight can be properly balanced at the hitching end part, so that the gravity center of the hitching part 100 is more stable, and a more comfortable use experience is provided. The interior of the hooking portion 100 may be further provided with a circuit structure such as a circuit board and a bluetooth module, so that the interior space of the hooking portion 100 is fully utilized. The connection part of the hooking part 100 and the abutting part 200 can be made of a memory alloy material such as copper-titanium alloy, copper-zinc alloy, etc., so that the hooking part 100 has the function of adjusting the wearing position, and the wearing comfort of the bone conduction earphone 1000 is improved.

As shown in fig. 1, one end of the abutment portion 200 is connected to one end of the hooking portion 100 and disposed at an angle such that the abutment portion 200 is placed in the ear of the person at an optimal angle when the bone conduction headset 1000 is in use, preferably, the abutment portion 200 may be placed in the concha cavity of the ear of the person, and abuts against the inner wall of the concha cavity, so that the abutment portion 200 is supported by the ear of the person. The external shape of the abutment portion 200 and the relative angle between the abutment portion 200 and the hooking portion 100 can be designed in combination with factors such as comfort requirements and fixing effects. As shown in fig. 2 and 3, in which fig. 3 is a partially enlarged view of a portion a in fig. 2, the other end of the abutting portion 200 is shown to be opened with a first hinge hole 210. Preferably, the axis direction of the first hinge hole 210 may be parallel to the Y-axis direction shown in fig. 3, which is the height direction of the bone conduction earphone 1000 with respect to the human body in use, and the optimal adjustment effect can be achieved when the abutment portion 200 and the fitting portion 300 are relatively rotated around the axis direction to adjust the relative angle toward the human body side.

As shown in fig. 1, the attaching portion 300 is disposed at an end of the abutting portion 200 away from the hooking portion 100, and when the bone conduction headset 1000 is used, the attaching portion 300 is attached to a human body, preferably, the attaching portion 300 may be attached to a skin surface at a position corresponding to a skull of the human body. As shown in fig. 2 and 3, a second hinge hole 310 is formed at one end of the attaching portion 300, and when assembled, the attaching portion 300 is adjacent to the abutting portion 200 in the X-axis direction shown in fig. 3 such that the second hinge hole 310 is coaxially disposed with the first hinge hole 210. The cushion pad made of a skin-friendly flexible material can be further covered on the side of the attaching part 300 attached to the human body, so that the touch feeling of the attaching part 300 is improved, and the attaching part 300 is more comfortable when attached to the human body.

The roll pin 400 is an elastic pin capable of being elastically deformed when it receives a pressing force in a radial direction, and the initial diameter of the roll pin 400 should be larger than the diameters of the first hinge hole 210 and the second hinge hole 310, and at the time of assembly, the roll pin 400 is first compressed to be reduced in diameter and then simultaneously coupled to the first hinge hole 210 and the second hinge hole 310 in a Y-axis direction as shown in fig. 3, so that the roll pin 400 is held closely to the inner walls of the first hinge hole 210 and the second hinge hole 310 to form an interference fit, while the elastic force generated by the compression of the roll pin 400 continuously presses the inner walls of the first hinge hole 210 and the second hinge hole 310. When the user adjusts the relative angle between the fitting portion 300 and the abutting portion 200, the first hinge hole 210 and the second hinge hole 310 rotate relatively about the common axis, and at this time, the rolling pin 400 applies a friction force to the inner walls of the first hinge hole 210 and the second hinge hole 310, and when the user stops the adjustment, the rolling pin 400 applies a friction force that can stop the relative rotation of the first hinge hole 210 and the second hinge hole 310 rapidly, thereby maintaining the adjusted state. It should be noted that, the initial diameter of the roll pin 400 should not be too large while satisfying the premise of being larger than the diameters of the first hinge hole 210 and the second hinge hole 310, otherwise the roll pin 400 needs to be compressed to a large extent before being installed in the first hinge hole 210 and the second hinge hole 310, which increases the difficulty of assembly; moreover, the excessive extrusion force and friction force of the roll pin 400 to the first hinge hole 210 and the second hinge hole 310 may cause abrasion of the hole wall, and may further cause more effort to the user when adjusting the angle, affecting the use experience.

As shown in fig. 4, a vibration structure 320 is provided in the attaching portion 300, and the vibration structure 320 converts sound into mechanical vibration, and when the attaching portion 300 is attached to a human body, sound information in a vibration form is transmitted by using a bone conduction principle, so that a person can hear the sound. Therefore, when the position of the attaching portion 300 is adjusted to the optimal position, the quality of the sound output can be improved.

Through the above embodiment, the relative included angle between the attaching portion 300 and the abutting portion 200 facing to one side of the human body is adjustable, and the adjusting can be kept unchanged after the completion of the adjustment, so that the attaching portion 300 and the human body are attached to each other with the best effect, the stability of the output sound quality is ensured, the wearing comfort of the bone conduction earphone is also improved, and the use experience is improved.

To make the connection between the abutment and the abutment more reliable and to facilitate the assembly operation, in some embodiments, optionally, please continue to refer to fig. 3, the abutment 200 is provided with a U-shaped connection 220 near an end of the first hinge hole 210; the first hinge hole 210 includes a through hole portion 211 and a blind hole portion 212 coaxially disposed with each other, the through hole portion 211 and the blind hole portion 212 being disposed at both ends of the U-shaped connection portion 220, respectively; the attaching part 300 is provided with a protruding part 330 near one end of the second hinge hole 310, the protruding part 330 is clamped between two ends of the U-shaped connecting part 220, the protruding part 330 is provided with the second hinge hole 310 in a penetrating way, and the second hinge hole 310 and the first hinge hole 210 are coaxially arranged; the winding pin 400 penetrates the through hole portion 211 and the second hinge hole 310 and is accessed into the blind hole portion 212, and one end of the winding pin 400 abuts against the bottom wall of the blind hole portion 212.

As shown in fig. 3, the U-shaped connection part 220 has a shape similar to a letter U, which includes two ends and a relatively concave portion between the two ends, and the two ends of the U-shaped connection part 220 are respectively provided with a through hole portion 211 and a blind hole portion 212 of the first hinge hole 210. Wherein the through hole portion 211 is penetratingly provided at one end of the U-shaped connection portion 220; the blind hole 212 is a non-through hole structure with one end being an orifice and the other end being a bottom wall, the blind hole 212 is provided at the other end of the U-shaped connecting portion 220, the orifice of the blind hole 212 faces one side of the through hole 211, and the blind hole 212 is provided coaxially with the through hole 211.

The protruding portion 330 is close to the U-shaped connecting portion 220 along the X direction shown in fig. 3, and is clamped at a relatively concave portion between two ends of the U-shaped connecting portion 220, so that a gap between two ends of the U-shaped connecting portion 220 is filled, and a connection portion between the abutting portion 200 and the attaching portion 300 can be more compact; on the other hand, in the use process, since the position of the protruding portion 330 is limited by the two ends of the U-shaped connecting portion 220, the attaching portion 300 is not easy to loose relatively, so that the stability of the connection between the attaching portion 300 and the abutting portion 200 is increased, and long-term use is facilitated.

The winding pin 400 penetrates the through hole portion 211 and the second hinge hole 310 in the Y direction shown in fig. 3 and is accessed into the blind hole portion 212, and one end of the winding pin 400 abuts against the bottom wall of the blind hole portion 212. The bottom wall of the blind hole portion 212 can limit the position of the roll pin 400 to facilitate the determination of whether the roll pin 400 is in place, and thus, the design of the above-described embodiment is also advantageous for assembly operations.

In some embodiments, as shown in fig. 3, a limiting portion 230 is disposed at an end of the abutting portion 200 near the first hinge hole 210, and the limiting portion 230 is used for abutting against the abutting portion 300 to limit a variation range of a relative angle between the abutting portion 200 and the abutting portion 300 toward the human body.

As an illustration, the stopper 230 may further include a first stopper 231 and a second stopper 232; the first limiting portion 231 may be disposed at an end portion of the U-shaped connection portion 220, and not limited thereto, the first limiting portion 231 may be disposed at an end having the through hole portion 211 and/or at an end having the blind hole portion 212, and when the abutting portion 200 and the fitting portion 300 are adjusted to have a relative angle toward a side close to the human body, the first limiting portion 231 is abutted to the fitting portion 300 for defining a minimum angle between the abutting portion 200 and the fitting portion 300; the second limiting portion 232 may be disposed between two ends of the U-shaped connecting portion 220, where when the abutting portion 200 and the attaching portion 300 are adjusted to a side far away from the human body, the second limiting portion 232 abuts against the attaching portion 300, so as to define a maximum included angle between the abutting portion 200 and the attaching portion 300.

The above embodiment provides the limiting portion 230 for limiting the range of the included angle between the abutting portion 200 and the attaching portion 300, so as to avoid the problem that the parts are seriously deformed or damaged due to careless operation when the user adjusts the included angle between the abutting portion 200 and the attaching portion 300, which is beneficial to the long-term use of the bone conduction earphone.

The flexible material comprises soft materials such as soft rubber materials or cloth, and the like, and according to the characteristics of the flexible materials, the protection cover 600 can adapt to the deformation generated by the change of the relative included angle between the abutting part 200 and the attaching part 300, so that the protection cover 600 always attaches to and wraps the joint of the abutting part 200 and the attaching part 300, and plays a role in protection. Preferably, the initial size of the protection cover 600 may be smaller than the overall size formed by combining the U-shaped connection portion 220, the protruding portion 330 and the winding pin 400, and when the protection cover 600 is properly unfolded and then wrapped outside the U-shaped connection portion 220, the protruding portion 330 and the winding pin 400, the connection portion between the abutment portion 200 and the attaching portion 300 is tightened by the elastic force of the protection cover 600, so that loosening of parts can be prevented, and the protection effect of the protection cover 600 is better. In addition, the protective cover 600 is made of flexible materials, so that the touch feeling of a user can be improved, and the protective cover 600 can cover the U-shaped connecting part 220, the protruding part 330, the winding pin 400 and other parts, so that the whole bone conduction headset 1000 is attractive.

To make the bone conduction headset 1000 more firm, in some embodiments, optionally, referring to fig. 6 and 7, a plug portion 260 is disposed on a side of the abutment portion 200 facing the inside of the human ear, the plug portion 260 is disposed at an angle to the abutment portion 200, and the plug portion 260 is used to plug into the human ear and clamp the human ear together with an end of the abutment portion 200 near the plug portion 260.

As shown in fig. 6, the plug 260 is connected to the abutment 200, and extends toward one side in the human ear when the bone conduction headset 1000 is in use, preferably, the plug 260 may extend toward the position inside the tragus of the human ear and abut against the tragus so that the plug 260 is supported by the human ear. The plug portion 260 is disposed at an angle with respect to the abutment portion 200, which is generally smaller than 90 degrees, so as to form a clamping effect with respect to the human ear together with the abutment portion 200, thereby improving the fixing effect of the bone conduction headset 1000. To improve the use experience, the plug portion 260 may preferably be made of a flexible material, such as a soft gel material, e.g., silicone, TPE, etc., to avoid squeezing the human ear with too hard a material. In addition, the plug 260 can be designed reasonably, for example, the surface of the plug 260 facing the inner side of the tragus is designed into a concave arc shape, so that the surface facing the inner side of the tragus is incompletely attached to the skin of the tragus, and only a small part of the end part is contacted with the tragus, thus the contact area is reduced, the foreign body sensation of a user can be reduced, and the wearing comfort level is increased.

When the bone conduction headset 1000 is used, for example, the right ear, as shown in fig. 7, the user's face is directed in the direction of the arrow shown in the figure, the hooking portion 100 is hooked on the back of the auricle of the right ear, and contact is made between the figure P1 and the vicinity thereof; the abutment portion 200 is placed in the concha cavity of the right ear, and is brought into contact with the inside of the concha at a position near the position P2 shown in the figure; the plug 260 is inserted into the tragus of the right ear, and is brought into contact with the tragus at a position near or at the position shown in the drawing P3; the attaching portion 300 is attached to the face of the user at the position shown by the drawing P4 and the vicinity thereof. The bone conduction earphone 1000 is worn at the right ear through the operation, and the stability of the fitting part 300 at the position of the figure P4 is ensured through the supporting function of the figures P1, P2 and P3 and the positions nearby, so that the bone conduction earphone 1000 can be firmly fixed at the right ear and is not easy to loose. The same is true for the wearing operation at the left ear.

Through the above embodiment, the bone conduction earphone 1000 forms a multi-point fixed support with the human ear through the hitching part 100, the abutting part 200 and the plug part 260, so that the stability of the fitting part 300 fitting with the human body is ensured, the bone conduction earphone 1000 has a more stable fixing effect, and meanwhile, the comfort level of wearing is good.

To increase the flexibility of assembly and further improve the use experience, in some embodiments, optionally, referring to fig. 6, the abutment 200 is detachably connected to the plug 260.

In view of the variability in ear configuration, it is desirable to personalize the abutment 200 and/or plug 260 to meet different use requirements. However, the modification of the abutment portion 200 is inconvenient in practical operation, and may affect the assembly effect with other portions, so that the personalized customization of the plug portion 260 is preferentially considered, and the cost of customization can be reduced; on the other hand, by setting the plug 260 to be detachably connected, the plug 260 can be replaced at any time, so that the flexibility of assembly can be improved, and different use requirements can be met. As an example, in the embodiment of the present application, the plug 260 and the abutment 200 are connected by an internally threaded cylindrical pin, specifically, the internally threaded cylindrical pin is fixed in the abutment 200 by a screw and protrudes toward the plug 260, and a pin hole is formed at a corresponding position of the plug 260 and is sleeved into the protruding end of the internally threaded cylindrical pin through the pin hole, so that the plug 260 and the abutment 200 are connected. In addition, the plug 260 and the contact 200 may be detachably connected by other means such as a snap-fit connection.

Through the above embodiment, the detachable connection of the abutting portion 200 and the plug portion 260 improves the flexibility of assembly, realizes personalized customization to meet different use demands, reduces customization cost, and improves use experience.

The application also provides an earphone set, which comprises the bone conduction earphone 1000 and a charging box, wherein the charging box is used for accommodating the bone conduction earphone 1000 and charging the bone conduction earphone 1000.
