Description

Technical Field

[0001] The present application relates to the technical field of sound-generating instruments, and in particular to an earphone. Background Art

[0002] Headphones have been widely used in people's daily life. They can be used with mobile phones, computers and other electronic devices to provide users with an auditory feast. According to the working principle of headphones, they can generally be divided into air conduction headphones and bone conduction headphones; according to the way users wear headphones, they can generally be divided into headphone, earhook headphones and in-ear headphones; according to the interaction between headphones and electronic devices, they can generally be divided into wired headphones and wireless headphones.

[0003] Due to differences in user heads and in different scenarios (such as sports and work), the balance conditions of ear-hook headphones when worn on the user's head are different, and existing headphones cannot make corresponding balance adjustments based on these differences. Summary of the invention

[0006] In some embodiments, the functional component is block-shaped, one end of the ear hook is connected to the width side of the functional component, and the back hook is movably connected between the two groups of ear hooks; wherein the total mass of the speaker component is greater than the sum of the total mass of the functional component and the back hook.

[0007] In some embodiments, in the wearing state, the ear hook is supported on the human ear, and the torque generated by the two groups of the speaker components is balanced with the torque generated by the two groups of the functional components and the back hook.

[0013] In some embodiments, two sets of the functional components are used to clamp both sides of a human head, and in a wearing state, the torques of the two sets of speaker components to the corresponding functional components are balanced with the torque of the rear hanger to the functional component.

[0032] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

Thus, the features defined with "first", "second", and "third" may explicitly or implicitly include at least one of such features. In the description of the present application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0034] Referring to "embodiment" herein means that a specific feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0035] The present application provides a headset 100. Refer to Figure 1 , Figure 1 which is a schematic structural diagram of an embodiment of the headset provided by the present application.

[0036] In the present application, the headset 100 can be a head-mounted headset. At this time, when the user wears the headset 100, mainly the weight of the headset 100 is borne by the user's head. For example, the weight of the headset 100 is borne by the human ear, or the weight of the headset 100 is borne by the human head.

[0037] Furthermore, for a head-mounted headset, the headset 100 can specifically be an air conduction headset, a bone conduction headset, or a combination air and bone conduction headset, where the combination air and bone conduction headset is a headset that simultaneously has air conduction and bone conduction. Among them, the embodiments of the present application take the headset 100 as a bone conduction head-mounted headset as an example for exemplary illustration.

[0038] Bone conduction headphones can transmit sound to a person's auditory system through his / her bones and can generate hearing. The bone conduction headphones can obtain a sound signal containing audio information and can generate vibrations according to the signal. The vibrations can be transmitted to the user's bones through a transmission component, and the user's auditory system can receive the vibrations through the bones to further perceive the audio information. In some embodiments, the bone conduction headphones can receive a signal containing audio information, convert the audio information into sound vibrations through a transducer, and then the sound can be transmitted to the user's sensory organs and the sound can be heard.

[0039] As Figure 1 shown, the headphone 100 may include a speaker assembly 10, a function assembly 20, an ear hook 30, and a rear hook 40. Among them, the speaker assembly 10 includes a movement housing and a headphone core. The movement housing is connected to one end of the ear hook 30 and is used to accommodate the headphone core; the function assembly 20 includes a function housing, a circuit board, and / or a battery. The function housing is used to accommodate the circuit board and / or the battery, and the function housing is connected to the other end of the ear hook 30; among them, the speaker assembly 10 can be bone conduction sound transmission or air conduction sound transmission. The function assembly 20 is electrically connected to the speaker assembly 10. The ear hook 30 is connected between the speaker assembly 10 and the function assembly 20, and the rear hook 40 is connected between two function assemblies 20 or between two ear hooks 30. The number of the speaker assembly 10, the function assembly 20, and the ear hook 30 can all be two, respectively corresponding to being worn on the left and right sides of the human head.

[0040] In the scenario where the user wears the headphone 100, the two groups of speaker assemblies 10 are respectively located on the left and right sides of the human head. Under the cooperation of the two ear hooks 30 and the rear hook 40, the two groups of speaker assemblies 10 can clamp the human head and contact the user's skin, so as to be able to realize the transmission of sound based on bone conduction technology.

[0041] Furthermore, the circuit board and the battery can be arranged in the same function housing, or can be respectively arranged in two function housings. And the circuit board and the battery can be electrically connected to each other through corresponding conductors, and further electrically connected to the headphone core in the speaker assembly 10 through the conductors. Among them, the circuit board can be used to control the sound generation of the headphone core, such as converting an electrical signal into mechanical vibrations to transmit sound to the user through bone conduction technology. The battery can be used to provide electrical energy for the headphone 100, for example, to supply power to the headphone core in the speaker assembly 10.

[0042] The headphone 100 described in this application may further include a microphone or a pickup such as a microphone, and may further include a communication device such as Bluetooth or NFC (Near Field Communication). They are electrically connected to the circuit board and the battery through corresponding conductors to realize corresponding functions.

[0043] It should be noted that: There are two sound - generating components 10 described in this application. Both of the two sound - generating components 10 can generate sound, mainly to facilitate the headset 100 to achieve stereo sound effects, thereby improving the acoustic performance of the headset 100. Therefore, in some other application scenarios where the requirement for stereo is not particularly high, such as hearing aid for hearing - impaired patients, (host) live teleprompter, etc., the headset 100 can also be provided with only one sound - generating component 10.

[0044] It should be noted that in this application, the orientations described in the description mostly adopt the scenario where the headset 100 is worn on the human head to describe, so as to more concisely and clearly express the features of the headset 100. However, biological features such as the human head should not be regarded as features of the headset protected by this application.

[0045] Connection method between the sound - generating component 10 and the ear hook 30

[0046] The sound - generating component 10 can be fixedly connected to the ear hook 30, and the sound - generating component 10 can also be movably connected to the ear hook 30.

[0047] The ear hook 30 and the sound - generating component 10 can be fixedly connected by gluing, clamping, riveting or integral injection molding, etc. The ear hook 30 and the sound - generating component 10 can also be movably connected by hinging or universal joints, etc.

[0048] The movement mechanism housing of the sound - generating component 10 includes a first movement mechanism housing part and a second movement mechanism housing part. The first movement mechanism housing part and the second movement mechanism housing part can be snap - fitted or connected by fasteners or adhesives, etc., and form a space for accommodating the earphone core.

[0049] The ear hook 30 includes a first ear - hook part and a second ear - hook part. The first ear - hook part and the second ear - hook part are connected by snap - fitting or using adhesives, etc. The first ear - hook part is provided with a wire - routing groove to accommodate the wire leading from the functional component 20 to the sound - generating component 10. The first ear - hook part and the second ear - hook part are connected to avoid the exposure of the wire.

[0050] Among them, the first ear - hook part is fixedly connected or movably connected to the first movement mechanism housing part.

[0051] In this embodiment, refer to Figure 2 , the sound - generating component 10 can be adjusted in posture relative to the ear hook 30, so that when the headset 100 is worn, the sound - generating component 10 can be adjusted in posture to fit the human head, avoiding the poor sound - transmission effect caused by the non - fitting of the sound - generating component 10 relative to the human head due to the skew of the sound - generating component 10 relative to the human head.

[0052] Specifically, when the sound - generating component 10 fits the human head, it should be understood that the surface of the sound - generating component 10 facing the human head side fits the human head.

[0053] In one embodiment, the ear hook 30 is a rigid ear hook. For example, the ear hook 30 is made of hard plastic or rubber, or a metal part such as a steel bar is embedded in the ear hook 30, so that the whole ear hook 30 is rigid and cannot be deformed.

[0054] Among them, as Figure 2 shown, the side of the speaker assembly 10 facing away from the human head is movably connected to one end of the ear hook 30, so as to facilitate the attitude adjustment of the speaker assembly 10 relative to the ear hook 30, and then be completely attached to the human head when worn.

[0055] Further, the speaker assembly 10 and the ear hook 30 are movably connected through a universal joint. Among them, a relatively smooth sphere is provided at one end of the ear hook 30 connected to the speaker assembly 10, a boss is provided on the side of the speaker assembly 10 facing away from the human head, and a groove is provided on the boss. The sphere is clamped in the groove, and the sphere can rotate in the groove to form a universal joint structure, that is, the sphere and the boss can rotate relative to each other to realize the attitude adjustment of the speaker assembly 10 relative to the ear hook 30.

[0056] By setting the sizes of the groove on the boss and the sphere, the attitude adjustment range of the speaker assembly 10 relative to the ear hook 30 can be adjusted. For example, the rotation angle range of the speaker assembly 10 relative to the ear hook 30 around the vertical direction is within plus or minus 5 degrees, and the rotation angle range of the speaker assembly 10 relative to the ear hook 30 around the horizontal direction is within plus or minus 10 degrees. Therefore, the problem that the speaker assembly 10 does not fit the face can be effectively improved, and the side surface of the speaker assembly 10 facing the human head can be completely attached to the human head, so as to achieve excellent sound transmission effect.

[0057] Further, referring to Figure 2 , the ear hook 30 includes a connected extension part 321 and a biasing part 322. One end of the extension part 321 is connected to the functional component 20, and the side of the extension part 321 facing away from the human head is coplanar with the side of the functional component 20 facing away from the human head. The biasing part 322 is biased away from the human head relative to the extension part 321, and one end of the biasing part 322 is movably connected to the speaker assembly 10. In other words, the thickness of the speaker assembly 10 is relatively thick, and the biasing part 322 is biased away from the human head relative to the extension part 321, so that the speaker assembly 10 can be offset away from the human head, avoiding the discomfort caused to the outer ear back by the functional component 20 abutting against the outer ear back due to the connection of the ear hook 30 and the side of the speaker assembly 10 facing away from the human head.

[0058] The speaker assembly 10 can also be hinged to the ear hook 30, and the hinging direction of the speaker assembly 10 and the ear hook 30 can be the vertical direction or the horizontal direction, so that the speaker assembly 10 can be adjusted in attitude relative to the ear hook 30 around the vertical direction or the horizontal direction.

[0059] The speaker assembly 10 can also be rotationally connected to one end of the earhook 30 through shaft-hole cooperation, that is, the speaker assembly 10 can rotate around the axis of the earhook 30 for attitude adjustment, which can improve the adaptability of the earphone 100, thereby achieving an improved fitting effect between the speaker assembly 10 and the human head.

[0060] In another embodiment, referring to Figure 3 , the earhook 30 is an elastic earhook, which can be made of materials such as silica gel, plastic or rubber with good elasticity, and the earhook 30 is fixedly connected to the speaker assembly 10 to utilize the self-elasticity of the earhook 30 to achieve the attitude adjustment of the speaker assembly 10 relative to the earhook 30.

[0061] As Figure 3 shown, the earhook 30 can be arc-shaped, the earhook 30 extends arc-shaped from above the speaker assembly 10, and the earhook 30 is fixedly connected to the front side surface 101 of the speaker assembly 10 facing away from the human ear. Specifically, the earhook 30 includes a connected arc segment 311 and a horizontal segment 312, wherein the arc segment 311 is arc-shaped and connected to the functional component 20, the horizontal segment 312 is linear and is horizontally arranged when the earphone 100 is worn on the human head, and one end of the horizontal segment 312 away from the arc segment 311 is connected to the speaker assembly 10, so as to utilize the elasticity of the earhook 30 to enable the speaker assembly 10 to perform attitude adjustment around the horizontal direction in the wearing state. For example, the rotation range of this attitude adjustment is plus or minus 10 degrees, so that the side surface of the speaker assembly 10 facing the human head completely fits the human head, thereby achieving an excellent sound transmission effect.

[0062] In a specific application scenario, when the surface of the speaker assembly 10 facing the human head is skewed relative to the human head, the contact between the human head and the surface of the speaker assembly 10 facing the human head can cause the speaker assembly 10 to be deflected by force, thereby achieving attitude adjustment and making the surface of the speaker assembly 10 facing the human head completely fit the human head.

[0063] Furthermore, from the end of the earhook 30 connected to the functional component 20 to the end connected to the speaker assembly 10, the earhook 30 gradually inclines towards the human head relative to the functional component 20, so that the distance between the two speaker assemblies 10 is less than the width of the human head. That is, when the earphone 100 is worn on the human head, the human head adaptively forms a pre-tightening force on the speaker assembly 10, which can further ensure the adaptive attitude adjustment of the speaker assembly 10 relative to the earhook 30 and make the side surface of the speaker assembly 10 facing the human head completely fit the human head.

[0064] In other embodiments, referring to Figure 4, the ear hook 30 is an elastic ear hook, and the ear hook 30 can also be fixedly connected to the lower side surface 102 of the sound generating component 10 facing the human chin. The ear hook 30 can be bent and extended between the sound generating component 10 and the human ear and connected to the lower side surface 102, or the ear hook 30 is bent and extended from the front side surface 101 of the sound generating component 10 facing away from the human ear and connected to the lower side surface 102.

[0065] As Figure 4 shown, the ear hook 30 can include a connected first bending portion 331 and a second bending portion 332. The first bending portion 331 is connected to the functional component 20 and bends towards the human chin relative to the functional component 20. The second bending portion 332 bends towards the lower side surface 102 of the ear hook 30 relative to the first bending portion 331 and is connected to the lower side surface 102. The second bending portion 332 includes a horizontally extending sub-portion 333 and a vertically extending sub-portion 334 that are bent and connected. The horizontally extending sub-portion 333 is connected to the first bending portion 331 and is bent relative to it to extend below the lower side surface 102 and extend substantially horizontally in the wearing state. The vertically extending sub-portion 334 is bent relative to the horizontally extending sub-portion 333 and extends substantially vertically in the wearing state, and the end of the vertically extending sub-portion 334 away from the horizontally extending sub-portion 333 is connected to the sound generating component 10. Thus, the elasticity of the ear hook 30 can be utilized to enable the sound generating component 10 to adjust its posture around the vertical direction in the wearing state. For example, the rotation range of this posture adjustment is plus or minus 10 degrees, so that the side surface of the sound generating component 10 facing the human head completely fits the human head, thereby achieving an excellent sound transmission effect.

[0066] Furthermore, the sound generating component 10 is inclined towards the human head relative to the ear hook 30. In other words, the sound generating component 10 is inclined towards the human head from one end of its connection with the ear hook 30 to the end away from the connection. Thus, when worn, a pre-tightening force is provided between the sound generating component 10 and the human head, and the sound generating component 10 can be adaptively adjusted in posture relative to the ear hook 30. Furthermore, the side surface of the sound generating component 10 facing the human head completely fits the human head.

[0067] Furthermore, the surface of the sound generating component 10 facing the human head includes a convex arc surface, that is, at least part of the surface of the sound generating component 10 facing the human head is a convex arc surface, so as to increase the upward frictional force when the sound generating component 10 fits the human face and improve the earthquake resistance of the earphone 100.

[0068] Furthermore, a sticking layer is provided at the side edge of the sound generating component 10 facing the human head. The sticking layer is used to stick to the human head. That is, when the side surface of the sound generating component 10 facing the human head fits the human face, the sticking layer can further strengthen this fitting relationship and slow down or even eliminate the situation where the sound generating component 10 does not fit and slips due to other factors. The sticking layer can be a medical glue or a hydrogel, etc., and it is replaceable.

[0069] Optionally, an anti-slip member is provided at the side edge of the speaker assembly 10 facing the human head to increase the frictional force between the side of the speaker assembly 10 facing the human head and the human head, and to slow down or even eliminate the situation where the speaker assembly 10 does not fit and slips due to other factors.

[0070] The anti-slip member can be an anti-slip sleeve. The anti-slip sleeve is sleeved on the side edge of the speaker assembly 10 facing the human head. The anti-slip sleeve is made of skin-friendly material, which can enhance the comfort of use. The anti-slip member can be an anti-slip rubber block. Its rubber material can effectively increase the frictional force, thus achieving an anti-slip effect. The anti-slip member can also be anti-slip silica gel, which can avoid the non-fitting and slipping of the speaker assembly 10 by virtue of the large friction coefficient of silica gel.

[0071] Furthermore, a plurality of convex particles are provided on the side of the anti-slip member facing away from the speaker assembly. The plurality of convex particles can increase the tightness of fit with the user and play a good anti-slip role.

[0072] Furthermore, a water-absorbing gel layer is also provided on the side of the speaker assembly 10 facing the human head. The water-absorbing gel layer is arranged at the position in contact with the facial skin. The water-absorbing gel layer can absorb the moisture at the position in contact with the facial skin, prevent the speaker assembly 10 from slipping when in contact with the facial skin, and further increase the frictional force between the speaker assembly 10 and the human head.

[0073] The ear hook 30 is rigidly connected between the speaker assembly 10 and the functional component 20

[0074] In this embodiment, referring to Figure 5 ..., the ear hook 30 is rigidly connected between the speaker assembly 10 and the functional component 20, and a fixed preset angle β is set between the first surface 103 of the speaker assembly 10 facing the human head and the second surface 201 of the functional component 20 facing the human head, so that when the first surface 103 is close to the human head, the functional component 20 does not contact the back of the outer ear, and the force generated by the contact between the first surface 103 and the human head is greater than or equal to 0.1 N and less than or equal to 4.5 N.

[0075] Among them, the first surface 103 can be in direct or indirect contact with the human head at least partially. 0.1 N is greater than the minimum force for the first surface 103 of the speaker assembly 10 to contact the human head, and 4.5 N is less than the minimum force for the first surface 103 of the speaker assembly 10 to cause pain to the human head. The force generated by the contact between the first surface 103 and the human head within the range of 0.1 N to 4.5 N can improve the transmission efficiency and sound quality transmitted by the speaker assembly 10 to the human head. The sound quality of the bone conduction headset 100 is related to the distribution of the force on the first surface 103 of the speaker assembly 10. The frequency response curve of the speaker assembly 10 can be the superposition of the frequency response curves of the points on the first surface 103. In some embodiments, the force between the first surface 103 and the human head can preferably be 0.2 N - 0.8 N; this force is more preferably 0.2 N - 3.6 N; further preferably, the force can be 0.2 N - 1.5 N; and further preferably, this force can be 0.3 N - 1.8 N.

[0076] Specifically, the earhook 30 is rigidly connected between the speaker assembly 10 and the functional assembly 20, which means that the earhook 30 is a rigid earhook, that is, the earhook 30 cannot be deformed, and the earhook 30 is fixedly connected to both the speaker assembly 10 and the functional assembly 20, so that the included angle formed between the first surface 103 and the second surface 201 is a preset fixed angle value β, so that when the first surface 103 is completely close to the human head, a gap is maintained between the functional assembly 20 and the outer ear back to prevent the functional assembly 20 from abutting against the outer ear back.

[0077] For example, in some scenarios, when the headset 100 is worn, the force generated by the contact between the first surface 103 of the speaker assembly and the human head is greater than or equal to 0.1 N and less than or equal to 4.5 N to ensure the transmission efficiency and sound quality. During the wearing process, the functional assembly 20 will cause discomfort and a sense of oppression to the user due to abutting against the outer ear back of the ear. For example, the functional assembly 20 is laterally deflected and abuts against the outer side of the ear back. Through a large number of experiments and tests, the inventor understands a plurality of head shape size data. There is an included angle between the facial area corresponding to the speaker assembly 10 in front of the ear and the brain area corresponding to the functional assembly 20 behind the ear, and this included angle is within a certain range. Therefore, by rigidly connecting the earhook 30 between the speaker assembly 10 and the functional assembly 20 and setting a preset included angle β between the first surface 103 and the second surface 201, when the first surface 103 is completely close to the human head, the functional assembly 20 is located in the space between the human head and the outer side of the ear back and does not contact either the human head or the outer side of the ear back, thereby preventing the functional assembly 20 from abutting against the outer ear back and solving the problem of discomfort and a sense of oppression caused by the functional assembly 20 abutting against the outer ear back.

[0078] Furthermore, through a large amount of research, it can be obtained that the approximate preset angle β between the first surface 103 and the second surface 201 is in the range of 5 degrees to 10 degrees. The preset angle β can be 5 degrees, 8 degrees, 10 degrees, etc. Within this angular range, when the first surface 103 is completely in contact with the human head, the functional component 20 can be located in the space between the human head and the outer side of the ear back and is not in contact with either the human head or the outer side of the ear back.

[0079] The first surface 103 is the side of the sound - emitting component 10 facing the human head, and the second surface 201 is the side of the functional component 20 facing the human head. The first surface 103 and the second surface 201 can be a flat surface or a convex arc surface. If the first surface 103 and / or the second surface 201 is an arc surface, then the preset angle β is the angle between the plane formed by the edge contour lines of the first surface 103 and the second surface 201, and the preset angle β can also be the angle between the tangent planes at the top of the arc surface.

[0080] Furthermore, in this embodiment, the first surface 103 may include a convex arc surface to increase the upward frictional force when the sound - emitting component 10 fits against the human face and improve the anti - vibration performance of the earphone 100. In other words, the first surface 103 may be partially a convex arc surface, or the first surface 103 is a convex arc surface. In the wearing state, this arc surface fits against the human face. Compared with the first surface 103 being a flat surface, it increases the contact area between the sound - emitting component 10 and the human face. When the user is in a moving state, the convex arc surface can also increase the resistance to the upward or downward movement of the earphone 100 to prevent the earphone 100 from flying up. When the user is in a non - moving state, it is more conducive to preventing the earphone 100 from slipping down. Further, with reference to Figure 1 and Figure 5 , one corner of the functional component 20 adjacent to the outer ear back is chamfered. The chamfer can be a right - angled chamfer or a rounded chamfer to leave a clearance space, which can reduce the risk of the functional component 20 contacting the outer ear back and further prevent the functional component 20 from abutting against the outer ear back.

[0081] The functional component 20 can be in a block shape. For example, the functional component 20 is a cuboid, and its length edge is set along the extending direction of the ear hook 30. Its width edge facing the outer ear back is likely to abut against the outer ear back, that is, one corner of the functional component 20 adjacent to the outer ear back is a corner on its width edge facing the outer ear back. After chamfering, it can further prevent the functional component 20 from abutting against the outer ear back.

[0082] Furthermore, with reference to Figure 5 and Figure 6 , the functional component 20 is telescopically connected to the ear hook 30, that is, the functional component 20 is fixedly connected to the ear hook 30 and can be telescoped through the ear hook 30 to adjust the position of the functional component 20, which can prevent the functional component 20 from abutting against the outer ear back.

[0083] The ear hook 30 includes a first tube body 31 and a second tube body 32. One end of the first tube body 31 is rigidly connected to the speaker assembly 10, the other end of the first tube body 31 is telescopically connected to one end of the second tube body 32, and the other end of the second tube body 32 is rigidly connected to the functional component 20.

[0084] The first tube body 31 and the second tube body 32 are slidably sleeved. One end of the second tube body 32 is slidably inserted into the other end of the first tube body 31 and can be fixed by fasteners such as screws, pins or lock nuts. That is, when the limiting and fixing effect of the fasteners such as screws, pins or lock nuts on the first tube body 31 and the second tube body 32 is released, the first tube body 31 and the second tube body 32 can slide relative to each other for adjustment, and the first tube body 31 and the second tube body 32 are fixed again by fasteners after adjustment.

[0085] In one embodiment, the first tube body 31 and the second tube body 32 are both provided with limiting holes, and screws or pins are inserted through the limiting holes to fix the first tube body 31 and the second tube body 32.

[0086] In another embodiment, the lock nut is screwed onto the end of the first tube body 31, and the position of the lock nut is adjusted by screwing to adjust the size of the port of the first tube body 31. When the port of the first tube body 31 is larger, the second tube body 32 can telescopically slide relative to the first tube body 31. When the port of the first tube body 31 is smaller, the port of the first tube body 31 presses the second tube body 32, thereby fixing the first tube body 31 and the second tube body 32.

[0087] Connection mode of the functional component 20 and the ear hook 30

[0088] In this embodiment, referring to Figure 8 , the ear hook 30 can be a rigid ear hook or an elastic ear hook. The functional component 20 is movably connected to the ear hook 30, and the functional component 20 can deflect following when touched by an external force, so as to avoid hitting the human head and the back of the outer ear, and avoid the functional component 20 from pressing against the human head and the back of the outer ear, so as to solve the problem of discomfort and pressure caused by the functional component 20 pressing against the back of the outer ear to the user.

[0089] Among them, when the functional component 20 is subjected to a certain pressing force from the human head or the back of the outer ear, it can deflect relatively around the extension axis of the ear hook 30 to avoid the human head or the back of the outer ear, so as to eliminate the discomfort and pressure caused by the functional component 20 pressing against the back of the outer ear or the human head.

[0090] In one embodiment, a rotating hole (not shown) is provided on the functional component 20, and one end of the ear hook 30 is rotatably connected to the rotating hole. The ear hook 30 can be inserted through the rotating hole and is in clearance fit with the rotating hole. The functional component 20 can deflect around the ear hook 30 under the action of an external force, so that when the back of the outer ear or the human head presses against the functional component 20, the functional component 20 can deflect adaptively to avoid causing discomfort and pressure.

[0091] Furthermore, the functional component 20 further includes a functional housing and a movable connecting member (not shown), and the ear hook 30 is movably connected to the functional housing via the movable connecting member, which may be a torsion spring or a damping shaft.

[0092] In one embodiment, the movable connecting member is a torsion spring, which is inserted into the ear hook 30 and cooperates with the functional housing. When the functional component 20 is subjected to an external force reaching the threshold of the torsion spring, the functional housing can deflect around the extension axis of the ear hook 30, wherein the threshold of the torsion spring can be set to be relatively small, so that the force generated when the functional housing contacts the human head or the back of the external ear can cause the functional component 20 to deflect without causing a sense of pressure.

[0093] In another embodiment, the movable connecting member is a damping shaft, one end of which is connected to the functional housing, and the other end of which is connected to the ear hook 30. When the external force on the functional component 20 reaches the threshold of the damping shaft, the functional component 20 deflects through the damping shaft, and thereafter the functional component 20 can remain relatively fixed with the ear hook 30. The threshold of the damping shaft is also set so that the external force can cause the functional component 20 to deflect without causing a sense of pressure.

[0094] Furthermore, the deflection angle of the functional component 20 relative to the ear hook 30 is within a range of positive and negative preset threshold angles, wherein when the functional component 20 is not deflected, the deflection angle is 0 degrees, and the deflection of the functional component 20 toward or away from the head can be defined as positive or reverse deflection, and the corresponding deflection angle is a positive angle or a negative angle.

[0095] Specifically, when the functional component 20 is not in contact with the human head and ears, the surface 201 of the functional component 20 facing the human head is in the first position; when the functional component 20 is worn, the surface 201 of the functional component 20 facing the human head is in the second position, wherein the deflection angle between the surface 201 of the functional component 20 facing the human head at the first position and the second position is within the range of positive and negative preset threshold angles.

[0096] In other words, when worn, the functional component 20 does not contact the human head and ears, the functional component 20 does not deflect, the surface 201 of the functional component 20 facing the human head is in the first position, and the deflection angle is 0 degrees; when worn, the functional component 20 may also contact the human head and ears, and then deflect, at this time the surface 201 is in the second position, and the deflection angle between the surface 201 at the first position and the second position is within the range of positive and negative preset threshold angles.

[0097] The value of the preset threshold angle is in the range of 10 to 20 degrees. The preset threshold angle can be 10, 14, 17 or 20 degrees.

[0098] In this embodiment, the preset threshold angle is 10 degrees, and the deflection angle of the functional component 20 relative to the ear hook 30 is within the range of plus or minus 10 degrees. For example, the functional component 20 deflects 5 degrees, 6 degrees, or 8 degrees in the positive or negative direction relative to the ear hook 30, etc.

[0099] Alternatively, the functional component 20 can also only deflect towards the side close to the human head or only deflect towards the side away from the human head, and the deflection angle between the surfaces of the functional component 20 facing the human head at the first position and the second position is within the range of 0 to the preset threshold angle.

[0100] Furthermore, one corner of the functional component 20 adjacent to the back of the outer ear is chamfered to prevent the functional component 20 from abutting against the back of the outer ear, which will not be elaborated here.

[0101] The connection method of the rear hook 40 with the functional component 20 or the ear hook 30

[0102] In this embodiment, refer to Figure 6 and Figure 9 , the rear hook 40 is connected between two groups of functional components 20 or two groups of ear hooks 30, that is, the rear hook 40 can be connected between two groups of functional components 20, and the rear hook 40 can also be connected between two groups of ear hooks 30. Among them, in the wearing state, the rear hook 40 can be located at the back of the head or on the top of the head.

[0103] Optionally, the rear hook 40 is fixedly connected to the functional component 20 or the ear hook 30, that is, the rear hook 40 cannot be adjusted. The rear hook 40 can be fixedly connected to the functional component 20 or the ear hook 30 by means of integral injection molding, bonding, or threaded connection, etc.

[0104] In this embodiment, the position of the rear hook 40 relative to the functional component 20 is adjustable to adjust the posture of the rear hook 40, thereby changing the centroid position of the rear hook 40 and adjusting the torque generated by the rear hook 40 to achieve the torque balance of the earphone 100 about the support position and increase the wearing stability of the earphone 100.

[0105] Optionally, the rear hook 40 is rotatably connected to the functional component 20 or the ear hook 30.

[0106] In one embodiment, refer to Figure 9 , the rear hook 40 is connected to two groups of ear hooks 30 and is used to be worn on the top of the head. Among them, the ear hook 30 is connected between the speaker component 10 and the functional component 20, and the ear hook 30 only plays a connecting role and does not need to support the ear.

[0107] In the wearing state, the rear hook 40 supports on the top of the head, that is, when the earphone 100 is worn on the human head, the support point of the earphone 100 is on the rear hook 40. In the stable wearing state of the earphone 100, the torque generated by the speaker component 10 is balanced with the torque generated by the functional component 20 about this support point.

[0108] Such asFigure 10 As shown, Figure 10 for Figure 9 , a schematic diagram of mechanical analysis of the earphone 100 in a wearing state is shown in the figure, wherein the back hanger 40 is worn on the top of the head, the weight of the earphone 100 is balanced by the supporting force provided by the human head, and the supporting point of the earphone 100 is on the back hanger 40, then m1g*r1=m2g*r2, wherein m1 is the mass of the speaker component 10, m2 is the mass of the functional component 20, r1 is the force arm from the center of mass of the speaker component 10 to the supporting point, r2 is the force arm from the center of mass of the functional component 20 to the supporting point, and g is the gravitational constant.

[0109] In this embodiment, by changing the spatial form of the rear hanger 40 connection, from the parallel rear hanger when worn to the upright vertical rear hanger, the rear hanger 40 bears the weight of the entire device, so that the support point of the earphone 100 is located on the rear hanger 40, thereby eliminating the balance arm of the center of mass of the rear hanger 40 at the support point of the earphone 100, and the torque balance in the wearing state can be achieved only by the speaker component 10 and the functional component 20.

[0110] Furthermore, if Figure 9 As shown, the back hanging 40 includes a first head-mounted part 411 and two second head-mounted parts 412, one end of the two second head-mounted parts 412 is rotatably connected to one end of the first head-mounted part 411, and the second head-mounted part 412 is also connected to the ear hook 30; wherein in the wearing state, the second head-mounted part 412 can be rotated around the vertical direction relative to the first head-mounted part 411, and the rotation range can be plus or minus 5 degrees or plus or minus 8 degrees, etc., thereby adjusting the speaker component 10 and the functional component 20 connected to the ear hook 30 to have a better wearing state with the human head.

[0111] From the perspective of force, the support point of the earphone 100 is on the top of the head, and the ear hooks 30, the speaker assembly 10 and the functional assembly 20 on both sides are symmetrically arranged. Therefore, the earphone 100 can easily achieve torque balance, and is also easy to fine-tune based on the differences in the human head to obtain a good wearing effect and facilitate the wearing stability of the earphone 100.

[0112] In another embodiment, see Figure 6 The functional component 20 is block-shaped, one end of the ear hook 30 is connected to the width side of the functional component 20, and the rear hook 40 is movably connected between the two groups of ear hooks 30; wherein the mass of the speaker component 10 is greater than the sum of the masses of the functional component 20 and the rear hook 40, so as to facilitate the balance adjustment of the earphone 100.

[0113] The functional component 20 is in a block shape, having two width sides, namely the two sides distributed along the width direction of the upper surface of the functional component 20, and two length sides, namely the two sides distributed along the length direction of the upper surface of the functional component. The two width sides are spaced apart from each other, and the two length sides are also spaced apart from each other. One end of the ear hook 30 is connected to the width side of the functional component 20, that is, the functional component 20 is arranged horizontally.

[0114] As Figure 7 shown, Figure 7 for Figure 6 the schematic diagram of the mechanical analysis of the earphone 100 in the wearing state shown in, when in the wearing state, the ear hook 30 supports on the human ear, the rear hook 40 is located behind the head, and the weight of the earphone 100 is mainly balanced by the supporting force provided by the human ear to the ear hook 30. The supporting point of the earphone 100 is on the ear hook 30. Then, the torque generated by the two groups of speaker components 10 is balanced with the torque generated by the two groups of functional components 20 and the rear hook 40, that is, m1g*r1 = m3g*r3 + m2g*r2, where m3 is the mass of the rear hook 40, and r3 is the lever arm from the center of mass of the rear hook 40 to the supporting point.

[0115] In this embodiment, the rear hook 40 is rotatably connected to the ear hook 30.

[0116] Specifically, as Figure 6 shown, a first hinge plate 34 is provided on the ear hook 30, and a second hinge plate 42 is provided at the end of the rear hook 40. The first hinge plate 34 and the second hinge plate 42 are connected by a rotating shaft, and the attitude of the rear hook 40 can be adjusted by rotation to change the position of the center of mass of the rear hook 40.

[0117] Among them, the ear hook 30 is used to support on the human ear, that is, the contact position between the ear hook 30 and the human ear is the supporting point, and the speaker component 10 and the functional component 20 are located on both sides of the supporting point, which is beneficial to torque balance. At the same time, with the adjustment of the rear hook 40, it is more beneficial to achieve torque balance for the differences of different human heads, thereby facilitating the wearing stability of the earphone 100.

[0118] Furthermore, the functional component 20 is telescopically connected to the ear hook 30 to adjust the position of the functional component 20 by telescoping, that is, the lever arms of the functional component 20 and the rear hook 40 relative to the supporting point can be adjusted to achieve torque balance, thereby increasing the wearing stability of the earphone 100.

[0119] For example, the rear hook 40 further includes a first sliding part 421 and two second sliding parts 422. The two ends of the first sliding part 421 are respectively slidably connected to the two second sliding parts 422, and one end of the second sliding part 422 is provided with a second hinge plate 42 and is hinged to the ear hook 30.

[0120] In other embodiments, refer to Figure 1 and Figure 12, both ends of the rear hook 40 can also be slidably connected to the corresponding functional components 20 respectively and can slide and adjust along the width sides of the functional components 20, and the position of the rear hook 40 can be adjusted by sliding.

[0121] Optionally, a slideway is provided in the width direction of the functional component 20, and a slider is provided at the end of the rear hook 40, and the slider is slidably assembled in the slideway. Or, a guide block is provided in the width direction of the functional component 20, and a guide shaft is connected to the end of the rear hook 40, and the guide shaft is slidably assembled with the guide block.

[0122] Among them, the functional component 20 is clamped to the human head by the elastic force provided by the rear hook 40. Therefore, the position where the functional component 20 contacts the human head is the support point, and the moment balance is achieved by adjusting the rear hook 40 and the speaker component 10 with respect to the support point, so as to increase the wearing stability of the earphone 100.

[0123] Such as Figure 6 and Figure 11 As shown, the rear hook 40 includes a first sliding portion 421 and two second sliding portions 422. Both ends of the first sliding portion 421 are slidably connected to the two second sliding portions 422 respectively, and the two second sliding portions 422 are fixedly connected to the functional component 20. The sliding connection method here will not be elaborated, and reference can be made to the description in the above embodiments.

[0124] In another embodiment, continue to refer to Figure 11 , the functional component 20 is in a block shape, and the rear hook 40 is connected to the two length sides of the functional component 20, that is, the functional component 20 is arranged vertically, so as to facilitate the functional component 20 to be clamped to the human head, and the rear hook 40 is telescopically connected to the functional component 20.

[0125] Furthermore, two groups of functional components 20 are used to clamp both sides of the human head, that is, the functional components 20 are directly used as the main support points. Therefore, the balance arm of the center of mass of the functional component 20 with respect to the support point can be almost ignored. The clamping force of the speaker component 10 is provided by the ear hook 30 alone. The normal pressure provided by the rear hook 40 to the functional component 20 generates a frictional force when contacting the human head, and this frictional force balances the gravity of the earphone 100.

[0126] In the wearing state, the moments of the two groups of speaker components 10 to the corresponding functional components 20 are balanced with the moments of the rear hook 40 to the functional components 20, that is, the moment generated by the center of mass of the speaker component 10 to the support point is equal to the moment generated by the center of mass of the rear hook 40 to the support point.

[0127] Specifically, as Figure 12 shown, Figure 12 is Figure 11The schematic diagram of torque balance when the earphone is in the wearing state is shown, in which the elastic force provided by the rear hanger 40 makes the two groups of functional components 20 clamped on both sides of the human head in the wearing state, and then the gravity of the earphone 100 is mainly balanced by the friction between the functional components 20 and the human head, that is, the supporting point of the earphone 100 is located on the functional component 20, then m1g*r1=m3g*r3, wherein m3 is the mass of the rear hanger 40, and r3 is the lever arm from the center of mass of the rear hanger 40 to the supporting point.

[0128] The mass of the ear hook 30 is extremely small compared to the mass of the speaker assembly 10, and the lever arm from its center of mass to the supporting point is also relatively short. Therefore, the torque generated by it is not of the same order of magnitude as the torque generated by the speaker assembly 10 and can be ignored.

[0129] Furthermore, the contact area between the functional component 20 and the human head can be relatively increased to reduce the pressure caused by the functional component 20 on the human head and improve wearing comfort.

[0130] Furthermore, the side of the functional component 20 facing the human head can be adapted to the corresponding area of ​​the human head, that is, the side of the functional component 20 facing the human head is contoured to better fit the human head, thereby increasing the contact area between the functional component 20 and the human head.

[0131] For example, the side of the functional component 20 facing the human head is concave to fit the human head, or the side of the functional component 20 facing the human head is provided with an elastic layer, which can also increase the contact area between the functional component 20 and the human head.

[0132] In another embodiment, if Figure 13 As shown, the functional component 20 is block-shaped, and the rear hanger 40 and the ear hanger 30 are respectively connected to the two width sides of the functional component 20, that is, the functional component 20 is arranged horizontally, and the rear hanger 40 is fixedly connected or telescopically connected to the functional component 20. Among them, the sum of the mass of the rear hanger 40 and the mass of the functional component 20 is less than the mass of the speaker assembly 10.

[0133] Specifically, in the wearing state, the ear hook 30 is supported on the human ear, so the supporting point of the earphone 100 is on the ear hook 30, the two groups of speaker components 10 are clamped on both sides of the human head, and the functional component 20 does not contact the human head. The torque generated by the two groups of speaker components 10 is balanced with the torque generated by the back hook 40 and the functional component 20, then m1g*r1+m3g*r3=M1, wherein M1 is the torque generated by the speaker component 10, including the torque generated by its gravity and the friction between the human head.

[0134] Integrated design

[0135] In this embodiment, refer to Figure 14, the ear hook 30 is connected between the speaker component (not shown) and the functional component 20, wherein the functional component 20 is connected to one end of the ear hook 30 and is arranged in a streamlined shape with the ear hook 30. In other words, the cross-section where the functional component 20 transitions to the ear hook 30 is gradually changing, and the functional component 20 is generally arranged along the extending direction of the ear hook 30. There is no obvious protrusion of the functional component 20 relative to the ear hook 30, which can also be understood that the cross-sections of the functional component 20 and the ear hook 30 along the extending direction are substantially the same, only with slight differences in size.

[0136] Therefore, the streamlined functional component 20 and ear hook 30 can avoid the discomfort and pressure caused by the functional component 20 squeezing the back of the ear.

[0137] Wherein, the slope of the functional component 20 relative to the ear hook 30 is within the range of 0 degrees to 15 degrees. For example, the slope can be 0 degrees, 3 degrees, 5 degrees, 8 degrees, 12 degrees or 15 degrees. In other words, in the extending direction, the slope of each point on the circumferential direction of the functional component 20 relative to the ear hook 30 is within the range of 0 to 15 degrees, so that the functional component 20 and the ear hook 30 can be arranged in a streamlined shape.

[0138] The length dimension of the functional component 20 along the extending direction of the ear hook 30 is greater than its body dimension in the direction perpendicular to the extending direction. The body dimension can be the width dimension, thickness dimension or radial dimension, etc. That is, the functional component 20 is in a long strip shape in the extending direction, so as to be arranged in a streamlined shape with the ear hook 30.

[0139] The ratio of the length dimension of the functional component 20 along the extending direction of the ear hook 30 to its body dimension in the direction perpendicular to the extending direction is less than 10. For example, the ratio of the length dimension to the body dimension is 6, and the body dimension includes the width dimension and the thickness dimension. The width dimension can be 6 mm, the thickness dimension can be 8 mm, and the length dimension can be 36 mm. The ratio of the length dimension to the body dimension can also be 5, 7, 8, 9 or 10.

[0140] Furthermore, the body dimension is less than or equal to 10 mm. Therefore, the width dimension of the battery or circuit board in the functional component 20 is less than 10 mm, which is different from the existing batteries or circuit boards with large width dimensions.

[0141] In this embodiment, the body dimension of the functional component 20 is 8 mm, and its length dimension is 40 mm.

[0142] The rear hook 40 is connected between two groups of functional components 20, and the rear hook 40 is connected to the end of the functional component 20 away from the ear hook 30 and is arranged in a streamlined shape with the functional component 20. The slope of the functional component 20 relative to the rear hook 40 is within the range of 0 degrees to 15 degrees.

[0143] Among them, the two sets of earhooks 30, the two sets of functional components 20 and the rear hook 40 are integrally designed. In other words, by designing the body sizes of the earhooks 30, the rear hook 40 and the functional components 20 to be substantially the same, the functional component 20 is connected to one end of the earhook 30 and to one end of the rear hook 40, and the slopes between the functional component 20 and the earhook 30 and between the functional component 20 and the rear hook 40 are small, so that they are overall streamlined and there are no obvious protrusions on their outer shapes.

[0144] Different from the prior art, the present application discloses a pair of earphones. By defining that the rear hook is connected between two sets of functional components or two sets of earhooks, and the position of the rear hook relative to the functional component is adjustable to adjust the posture of the rear hook, and then change the centroid position of the rear hook, and adjust the torque generated by the rear hook, so as to cooperate with the speaker component, the functional component and the earhook to achieve the torque balance of the earphone with respect to the support position, which is beneficial to the balance adjustment of the earphone and can increase the wearing stability of the earphone.

[0145] The above are only the embodiments of the present application, and do not limit the patent scope of the present application. Moreover, the features in the above embodiments can be combined with each other. Any equivalent structure or equivalent process transformation and combination made by using the content of the specification and drawings of the present application, or directly or indirectly applied to other related technical fields, are similarly included in the patent protection scope of the present application.
