Description

Technical Field

[0001] This application relates to the technical field of wearable devices, and particularly to an earclip-type earphone and a headphone device. Background Art

[0002] As a new type of wearable audio device, the earclip-type earphone realizes sound conduction by clamping on the outside of the wearer's auricle. Compared with traditional semi-in-ear earphones and in-ear earphones, it has advantages such as good wearing comfort and being suitable for long-term wearing.

[0003] In the related art, even though the earclip-type earphone has certain advantages compared with the above-mentioned semi-in-ear earphones and in-ear earphones, for the earclip-type earphone itself, due to the different shapes and sizes of the auricles of different wearers, it is difficult for the earclip-type earphone to fit different wearers, and there will still be problems of poor wearing comfort or poor stability. For example, when the sound output part of the earclip-type earphone is inserted too deeply, it will cause excessive pressure in the concha area and result in wearing pain. When the sound output part is inserted too shallowly, it will cause instability during exercise scenarios, which to a certain extent affects the user experience of the wearer. Summary of the Invention

[0004] This application discloses an earclip-type earphone and a headphone device to solve the problems of poor wearing comfort or poor stability existing in the earclip-type earphone in the related art.

[0005] To solve the above technical problems, this application is implemented as follows: In a first aspect, an embodiment of this application discloses an earclip-type earphone. The disclosed earclip-type earphone includes a sound output part, a clamping part, a bridging arm, and a center-of-gravity adjustment part; The first end of the bridging arm is connected to the sound output part, and the second end of the bridging arm is connected to the clamping part. In the wearing state, the sound output part is configured to abut against the inner side of the auricle, the clamping part is configured to abut against the outer side of the auricle, and the bridging arm is configured to bypass the helix and provide a clamping force for clamping the sound output part and the clamping part on both sides of the auricle; The center-of-gravity adjustment part is connected to the bridging arm, and the center-of-gravity adjustment part has a first state and a second state. When the center-of-gravity adjustment part is in the first state, the center-of-gravity adjustment part can move along the length direction of the bridging arm to adjust the center of gravity of the earclip-type earphone. When the center-of-gravity adjustment part is in the second state, the center-of-gravity adjustment part remains relatively stationary with respect to the bridging arm.

[0006] In a second aspect, an embodiment of this application discloses a headphone device. The disclosed headphone device includes a headphone case and the above-mentioned earclip-type earphone. The headphone case has an accommodation space inside, and the earclip-type earphone is placed in the accommodation space.

[0007] The technical solution adopted in this application can achieve the following technical effects: The earclip-type earphone disclosed in the embodiment of this application improves the related technology. By setting a center-of-gravity adjustment part on the bridging arm, when the position where the sound output part is worn inside the auricle is too deep or too shallow, the center-of-gravity adjustment part can be controlled to be in the first state, so that the center-of-gravity adjustment part can move along the length direction of the bridging arm, thereby adjusting the center of gravity of the earclip-type earphone. When the center of gravity of the earclip-type earphone changes, the acting forces exerted on the auricle by the sound output part and the clamping part will also change accordingly. The center of gravity of the earclip-type earphone can be adjusted according to the actual wearing posture, so that the sound output part and the clamping part will neither overly press the auricle nor become loose, and further enable the earclip-type earphone to reach a relatively comfortable and stable wearing state with the wearer's auricle; after the position adjustment of the center-of-gravity adjustment part is completed, the center-of-gravity adjustment part can be controlled to be in the second state, so that the center-of-gravity adjustment part remains relatively stationary with the bridging arm, avoiding the problem that the position of the center-of-gravity adjustment part needs to be frequently adjusted due to shaking.

Detailed Description of the Embodiment

[0010] To make the objectives, technical solutions and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments of this application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts belong to the scope of protection of this application.

It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of this application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually of the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally means that the associated objects before and after are in an "or" relationship.

[0012] The following will detail the technical solutions disclosed in each embodiment of this application with reference to the drawings.

[0013] Please refer to Figures 1 to 5 , an earclip-type earphone is disclosed in an embodiment of this application. The disclosed earclip-type earphone may include a sound output part 110, a clamping part 120, a bridging arm 130, and a center-of-gravity adjustment part 140. Among them, the sound output part 110 is internally provided with a sound generating unit for converting an electrical signal into a sound wave, which is the core component of the earclip-type earphone. In addition, the sound output part 110 may also be internally provided with a main control chip, and a Bluetooth module, a radio frequency antenna, a signal processing module, etc. may be integrally arranged on the main control chip; the clamping part 120 is internally provided with components such as a battery, which can supply power to the main control chip and the sound generating unit. With this layout of the sound output part 110 and the clamping part 120, it is beneficial to balance the weight distribution of the earclip-type earphone and avoid the problem of excessive weight on one side.

[0014] The bridging arm 130 has opposite first and second ends. The bridging arm 130 can be in an arched structure. The first end of the bridging arm 130 is connected to the sound output part 110, and the second end of the bridging arm 130 is connected to the clamping part 120. The specific connection methods can be snap connection, bolt connection, etc. When the earclip-type earphone is in a worn state, the sound output part 110 is configured to abut against the inner side of the auricle, specifically, it can abut against the inner wall of the wearer's concha cavity. The clamping part 120 is configured to abut against the outer side of the auricle, and the bridging arm 130 is configured to bypass the helix and provide a clamping force for clamping the sound output part 110 and the clamping part 120 on both sides of the auricle. The bridging arm 130 can be made of an elastic material. The inside of the bridging arm 130 can adopt a hollow structure. The inside of the bridging arm 130 is respectively connected to the inside of the sound output part 110 and the inside of the clamping part 120, so as to facilitate the electrical connection between the built-in components of the sound output part 110 and the built-in components of the clamping part 120.

[0015] Considering that the auricle shapes and sizes of different wearers are different, during the actual wearing process, the wearing posture of the earclip-type earphone is greatly affected by the auricle shape and size. From the perspective of the specific wearing posture, if the sound output part 110 of the earclip-type earphone is worn too deep, it will cause excessive pressure in the concha cavity area and cause wearing pain. When the sound output part 110 is worn too shallow, it will cause the problem of unstable wearing in the movement scenario.

[0016] To solve the above problems, a center of gravity adjustment part 140 can be added to the earclip-type earphone. The center of gravity adjustment part 140 can be in a ring structure, a block structure, an arc structure, etc. The center of gravity adjustment part 140 is connected to the bridging arm 130. The specific connection methods can include sliding connection, threaded connection, etc. The center of gravity adjustment part 140 has a first state and a second state. When the center of gravity adjustment part 140 is in the first state, the center of gravity adjustment part 140 can move along the length direction of the bridging arm 130, so as to adjust the center of gravity of the earclip-type earphone. It should be noted that when the center of gravity adjustment part 140 moves along the length direction of the bridging arm 130, the included motion states can be sliding or rotational motion along a screw pair. Taking sliding as an example, the center of gravity adjustment part 140 and the bridging arm 130 can be in frictional contact, or a slide rail pair can be set between the center of gravity adjustment part 140 and the bridging arm 130 to restrict the movement path of the center of gravity adjustment part 140. Taking the rotational motion along a screw pair as an example, the center of gravity adjustment part 140 can be a nut, the inner side of the center of gravity adjustment part 140 is provided with internal threads, the surface of the bridging arm 130 is provided with external threads, and the external threads extend along the length direction of the bridging arm 130. By rotating the center of gravity adjustment part 140, it can be made to rotate along the length direction of the bridging arm 130.

[0017] By adjusting the relative position of the center-of-gravity adjustment part 140 and the bridging arm 130, the center of gravity of the earclip-type earphone can be changed, so that the pressure between the sound output part 110 and the inner side of the auricle and the pressure between the clamping part 120 and the outer side of the auricle can be adjusted. In combination with a specific usage scenario, when the sound output part 110 extends too far into the auricle and the pressure between the sound output part 110 and the inner side of the auricle is too large, the center-of-gravity adjustment part 140 can be adjusted to a position close to the clamping part 120 (such as Figure 2 shown), so that the center of gravity of the earclip-type earphone changes, which enables a part of the weight of the earclip-type earphone to be transferred to a position close to the clamping part 120, thereby reducing the pressure between the sound output part 110 and the inner side of the auricle, and at the same time balancing the pressure between the clamping part 120 and the outer side of the auricle, avoiding the problem of wearing pain; similarly, when the sound output part 110 is worn too shallowly and the pressure between the sound output part 110 and the inner side of the auricle is small, the center-of-gravity adjustment part 140 can be adjusted to a position close to the sound output part 110 (such as Figure 3 shown), so as to increase the pressure between the sound output part 110 and the inner side of the auricle, and at the same time balance the pressure between the clamping part 120 and the outer side of the auricle, thereby improving the wearing stability.

[0018] The adjustment method of the above-mentioned center-of-gravity adjustment part 140 can be manual adjustment, or the earclip-type earphone can automatically adjust according to the detected wearing state, such as by magnetic drive, motor drive, etc., and the embodiments of the present application do not limit this.

[0019] After completing the position adjustment of the center-of-gravity adjustment part 140, that is, when the earclip-type earphone reaches a relatively comfortable and stable wearing state with the wearer's auricle, in order to avoid adjustment failure, the center-of-gravity adjustment part 140 can be controlled to be in the second state, so that the center-of-gravity adjustment part 140 and the bridging arm 130 remain relatively stationary, avoiding the center-of-gravity adjustment part 140 from moving again due to shaking.

[0020] Exemplarily, taking sliding as an example, structures such as friction plates and teeth can be provided between the center-of-gravity adjustment part 140 and the bridging arm 130. By changing the distance between the center-of-gravity adjustment part 140 and the bridging arm 130, the friction force between the center-of-gravity adjustment part 140 and the bridging arm 130 is increased or decreased. When the friction force between the center-of-gravity adjustment part 140 and the bridging arm 130 is relatively large, correspondingly, the center-of-gravity adjustment part 140 is in the second state, and at this time the center-of-gravity adjustment part 140 and the bridging arm 130 can remain relatively stationary; when the friction force between the center-of-gravity adjustment part 140 and the bridging arm 130 is relatively small, correspondingly, the center-of-gravity adjustment part 140 is in the first state, and at this time the center-of-gravity adjustment part 140 slides along the length direction of the bridging arm 130.

[0021] As described above, the ear clip earphone disclosed in the embodiment of the present application improves the related art. By setting the center of gravity adjustment part 140 on the bridging arm 130, when the sound outlet part 110 is worn too deep or too shallow inside the auricle, the center of gravity adjustment part 140 can be controlled to be in the first state, so that the center of gravity adjustment part 140 can be moved along the length direction of the bridging arm 130, so that the center of gravity of the ear clip earphone can be adjusted. When the center of gravity of the ear clip earphone changes, the forces applied to the auricle by the sound outlet part 110 and the clamping part 120 will also change accordingly, and the center of gravity of the ear clip earphone can be adjusted according to the change of the center of gravity. The center of gravity of the ear clip earphone is adjusted according to the actual wearing posture, so that the sound output part 110 and the clamping part 120 will neither over-press the auricle nor become loose, thereby making the ear clip earphone and the wearer's auricle reach a relatively comfortable and stable wearing state; after the position adjustment of the center of gravity adjustment part 140 is completed, the center of gravity adjustment part 140 can be controlled to be in the second state, so that the center of gravity adjustment part 140 and the bridging arm 130 remain relatively still, thereby avoiding the problem of frequent adjustments due to changes in the position of the center of gravity adjustment part 140 caused by shaking.

[0022] In an optional embodiment of the present application, Figures 1 to 3 As shown, the center of gravity adjustment part 140 can be driven by magnetic force and rely on magnetic force to maintain a balanced state. Specifically, the ear clip type earphone can also include a first electromagnetic component 150 and a second electromagnetic component 160. The first electromagnetic component 150 is arranged at the sound outlet 110, and can be arranged inside the sound outlet 110 or outside the sound outlet 110. It should be noted that when the first electromagnetic component 150 is arranged outside the sound outlet 110, in order to avoid the first electromagnetic component 150 being exposed, a protective shell can be installed outside the first electromagnetic component 150. The second electromagnetic component 160 is arranged at the clamping part 120. Similarly, the second electromagnetic component 160 can be arranged inside the clamping part 120 or outside the clamping part 120.

[0023] The center of gravity adjustment part 140 is a magnetic part, which can be a neodymium iron boron magnet, a samarium cobalt magnet, a ferrite magnet, an aluminum nickel cobalt magnet, an iron chromium cobalt magnet, etc. The magnetic part has a first magnetic pole and a second magnetic pole. The first magnetic pole can be an N pole, and the second magnetic pole is an S pole. Similarly, the first magnetic pole can be an S pole, and the second magnetic pole is an N pole. The first magnetic pole of the center of gravity adjustment part 140 is close to the first electromagnetic component 150, and the first electromagnetic component 150 is used to apply a first magnetic repulsion force to the center of gravity adjustment part 140. The second magnetic pole of the center of gravity adjustment part 140 is close to the second electromagnetic component 160, and the second electromagnetic component 160 is used to apply a second magnetic repulsion force to the center of gravity adjustment part 140.

[0024] According to the principle of electromagnetism, when current is passed through the first electromagnetic component 150 and the second electromagnetic component 160, magnetic forces will be generated on the center-of-gravity adjustment part 140 in the magnetic field respectively. The direction of the magnetic force is determined by the direction of the current and the direction of the magnetic field, following the right-hand rule. Here, the first magnetic repulsive force and the second magnetic repulsive force can be generated on the center-of-gravity adjustment part 140 by presetting the current direction for the first electromagnetic component 150 and the second electromagnetic component 160 respectively. The magnitudes of the first magnetic repulsive force and the second magnetic repulsive force are proportional to the square of the current, and different magnitudes of the first magnetic repulsive force and the second magnetic repulsive force can be generated by changing the magnitudes of the current in the first electromagnetic component 150 and the second electromagnetic component 160. At the same time, the magnitude of the first magnetic repulsive force received by the center-of-gravity adjustment part 140 is related to the distance between the center-of-gravity adjustment part 140 and the first electromagnetic component 150. Similarly, the magnitude of the second magnetic repulsive force received by the center-of-gravity adjustment part 140 is related to the distance between the center-of-gravity adjustment part 140 and the second electromagnetic component 160.

[0025] It can be understood that when the currents passed through the first electromagnetic component 150 and the second electromagnetic component 160 remain unchanged, the magnitudes of the first magnetic repulsive force and the second magnetic repulsive force will change in real time during the movement of the center-of-gravity adjustment part 140. Then, the relationship between the center-of-gravity adjustment part 140 and the first magnetic repulsive force and the second magnetic repulsive force can be as follows: when the first magnetic repulsive force and the second magnetic repulsive force are not equal, the difference between the first magnetic repulsive force and the second magnetic repulsive force can drive the center-of-gravity adjustment part 140 to slide along the length direction of the bridging arm 130 (corresponding to the center-of-gravity adjustment part 140 being in the first state). During the sliding process of the center-of-gravity adjustment part 140, the first magnetic repulsive force and the second magnetic repulsive force will change in real time. When the first magnetic repulsive force and the second magnetic repulsive force are equal, the center-of-gravity adjustment part 140 and the bridging arm 130 will remain relatively stationary (corresponding to the center-of-gravity adjustment part 140 being in the second state).

[0026] In combination with a specific usage scenario, when the sound output part 110 extends too far into the inner part of the auricle and the pressure between the sound output part 110 and the inner side of the auricle is too large, the current of the first electromagnetic component 150 can be increased, or the current of the second electromagnetic component 160 can be decreased. Of course, the current of the first electromagnetic component 150 can also be increased while the current of the second electromagnetic component 160 is decreased, as long as the first magnetic repulsive force can be made greater than the second magnetic repulsive force. Due to the larger first magnetic repulsive force, under the action of the first magnetic repulsive force, the center-of-gravity adjustment part 140 can slide along the bridging arm 130 and gradually approach the clamping part 120 (such as Figure 2As shown), the center of gravity of the ear clip earphone changes, which allows part of the weight of the ear clip earphone to be transferred to a position close to the clamping portion 120, thereby reducing the pressure between the sound outlet 110 and the inner side of the auricle, while balancing the pressure between the clamping portion 120 and the outer side of the auricle, avoiding the problem of wearing pain. It should be noted that in the process of the center of gravity adjustment portion 140 gradually approaching the clamping portion 120, the distance between the first electromagnetic component 150 and the center of gravity adjustment portion 140 becomes farther, the first magnetic repulsion force decreases, and the distance between the second electromagnetic component 160 and the center of gravity adjustment portion 140 becomes closer, so that the second magnetic repulsion force increases, until the first magnetic repulsion force is equal to the second magnetic repulsion force, the center of gravity adjustment portion 140 can be in a balanced state again, at which time, the center of gravity adjustment portion 140 and the bridging arm 130 can remain relatively still.

[0027] Similarly, when the sound outlet 110 is worn too shallowly and the pressure between the sound outlet 110 and the inner side of the auricle is small, the current of the first electromagnetic component 150 and / or the second electromagnetic component 160 can be controlled so that the first magnetic repulsion force is smaller than the second magnetic repulsion force. Since the second magnetic repulsion force is larger, under the action of the second magnetic repulsion force, the center of gravity adjustment part 140 can slide along the bridging arm 130 and gradually approach the sound outlet 110 (such as Figure 3 As shown in the figure, the center of gravity of the ear clip earphone changes, which allows part of the weight of the ear clip earphone to be transferred to a position close to the sound outlet 110, thereby increasing the pressure between the sound outlet 110 and the inner side of the auricle, while balancing the pressure between the clamping part 120 and the outer side of the auricle, avoiding the problem of wearing pain.

[0028] For the above-mentioned solution of arranging the first electromagnetic assembly 150 and the second electromagnetic assembly 160 inside the sound outlet 110 and the clamping part 120, specifically, the sound outlet 110 may include a first shell 111, the first shell 111 is connected to the first end of the bridge arm 130, the first shell 111 has a first accommodating cavity 112, and the first electromagnetic assembly 150 may be arranged in the first accommodating cavity 112. The clamping part 120 may include a second shell 121, the second shell 121 is connected to the second end of the bridge arm 130, the second shell 121 has a second accommodating cavity 122, and the second electromagnetic assembly 160 may be arranged in the second accommodating cavity 122. By respectively placing the first electromagnetic assembly 150 and the second electromagnetic assembly 160 inside the sound outlet 110 and the clamping part 120, the consistency and aesthetics of the ear clip type earphone can be improved.

[0029] In an optional embodiment of the present application, Figures 1 to 3 As shown, in order to improve the stability of the cooperation between the center of gravity adjusting part 140 and the bridging arm 130 , the center of gravity adjusting part 140 may adopt an annular structure, and the center of gravity adjusting part 140 is sleeved outside the bridging arm 130 and slidably connected to the bridging arm 130 .

[0030] In the above solution, the wearer can manually adjust the relative position of the center-of-gravity adjustment part 140 and the bridging arm 130 according to the actual wearing situation. Taking the driving of the center-of-gravity adjustment part 140 to slide by the first electromagnetic component 150 and the second electromagnetic component 160 as an example, a button can be set on the earclip-type earphone, and the wearer can manually adjust the current magnitude of the first electromagnetic component 150 and / or the second electromagnetic component 160 according to the actual wearing situation. Of course, the current magnitude of the first electromagnetic component 150 and / or the second electromagnetic component 160 can also be adjusted automatically. In the automatic adjustment solution, the earclip-type earphone can further include a first pressure sensor 170 and a second pressure sensor 180. The first pressure sensor 170 and the second pressure sensor 180 can be a strain-type pressure sensor, a piezoresistive pressure sensor, a capacitive pressure sensor, a piezoelectric pressure sensor, etc.

[0031] The first pressure sensor 170 is disposed in the first accommodation cavity 112 and close to the area of the sound output part 110 for abutting against the inner side of the auricle, so that when the sound output part 110 abuts against the inner side of the auricle, the pressure data of the sound output part 110 can be collected. The first electromagnetic component 150 can adjust its own current according to the detection data of the first pressure sensor 170, and further adjust the magnitude of the first magnetic repulsive force. The second pressure sensor 180 is disposed in the second accommodation cavity 122 and close to the area of the clamping part 120 for abutting against the outer side of the auricle, so that when the clamping part 120 abuts against the outer side of the auricle, the pressure data of the clamping part 120 can be collected. The second electromagnetic component 160 can adjust its own current according to the detection data of the second pressure sensor 180, and further adjust the magnitude of the second magnetic repulsive force. It should be noted that there is a preset correspondence relationship between the detection data of the first pressure sensor 170 and the current magnitude of the first electromagnetic component 150. Similarly, there is also a preset correspondence relationship between the detection data of the second pressure sensor 180 and the current magnitude of the second electromagnetic component 160. This preset correspondence relationship can be obtained through experiments.

[0032] In view of a specific usage scenario, when the detection data of the first pressure sensor 170 is too large and the detection data of the second pressure sensor 180 is too small, it indicates that the pressure between the sound output part 110 and the inner side of the auricle is too large, while the pressure between the clamping part 120 and the outer side of the auricle is too small. Then, the current magnitude of the first electromagnetic component 150 and / or the second electromagnetic component 160 can be controlled so that the first magnetic repulsive force is greater than the second magnetic repulsive force, enabling the center of gravity adjustment part 140 to slide along the bridging arm 130 and gradually approach the clamping part 120, causing a change in the center of gravity of the earclip-type earphone. Similarly, when the detection data of the first pressure sensor 170 is too small and the detection data of the second pressure sensor 180 is too large, it indicates that the pressure between the sound output part 110 and the inner side of the auricle is too small, while the pressure between the clamping part 120 and the outer side of the auricle is too large. Then, the current magnitude of the first electromagnetic component 150 and / or the second electromagnetic component 160 can be controlled so that the first magnetic repulsive force is less than the second magnetic repulsive force, enabling the center of gravity adjustment part 140 to slide along the bridging arm 130 and gradually approach the sound output part 110, causing a change in the center of gravity of the earclip-type earphone.

[0033] As Figures 1 to 3 shown, the structures of the above-mentioned first electromagnetic component 150 and second electromagnetic component 160 can be the same, and both include a circuit board 151 and an electromagnetic coil 152. The circuit board 151 is electrically connected to the electromagnetic coil 152. The cooperation relationship among the first electromagnetic component 150, the second electromagnetic component 160, the first pressure sensor 170, and the second pressure sensor 180 is as follows: The circuit board 151 of the first electromagnetic component 150 can be connected to the first pressure sensor 170, and the circuit board 151 of the first electromagnetic component 150 can control the current magnitude of the electromagnetic coil 152 of the first electromagnetic component 150 according to the detection data of the first pressure sensor 170; the circuit board 151 of the second electromagnetic component 160 can be connected to the second pressure sensor 180, and the circuit board 151 of the second electromagnetic component 160 can control the current magnitude of the electromagnetic coil 152 of the second electromagnetic component 160 according to the detection data of the second pressure sensor 180. Alternatively, the circuit board 151 of the first electromagnetic component 150, the circuit board 151 of the second electromagnetic component 160, the first pressure sensor 170, and the second pressure sensor 180 can be respectively connected to the main control chip of the earclip-type earphone, and be uniformly controlled by the main control chip.

[0034] In an alternative embodiment of the present application, as Figure 4 and Figure 5As shown, a damping structure 131 is provided on the surface of the bridging arm 130. The damping structure 131 can be a friction plate, a toothed gear, etc. The center-of-gravity adjustment part 140 can include an adjustment body 141 and a mating structure 142. The adjustment body 141 is slidably connected to the bridging arm 130, and the mating structure 142 is provided on one side of the adjustment body 141 close to the bridging arm 130. The mating structure 142 has a first position away from the damping structure 131 and a second position close to the damping structure 131. When the mating structure 142 is in the first position, the frictional resistance between the mating structure 142 and the damping structure 131 is small. At this time, the center-of-gravity adjustment part 140 can slide along the length direction of the bridging arm 130 to adjust the center of gravity of the earclip-type earphone. When the mating structure 142 is in the second position, the frictional resistance between the mating structure 142 and the damping structure 131 is large. At this time, the center-of-gravity adjustment part 140 remains relatively stationary with respect to the bridging arm 130.

[0035] The driving force for the mating structure 142 to switch between the first position and the second position can be manual or can be achieved by driving components such as motors and cylinders. Using the above mechanical linkage method, the structure is simple and the stability is good.

[0036] As Figure 4 and Figure 5 shown, the above damping structure 131 can include a plurality of ratchet teeth 1311. The plurality of ratchet teeth 1311 are sequentially connected along the length direction of the bridging arm 130. The adjustment body 141 can be an annular structure. The adjustment body 141 is sleeved on the bridging arm 130 to improve the assembly stability between the adjustment body 141 and the bridging arm 130. The adjustment body 141 has an installation groove 1411. The notch of the installation groove 1411 is located on the side of the adjustment body 141 close to the bridging arm 130, that is, the inner ring surface of the adjustment body 141. The mating structure 142 can include a telescopic member 1421. The telescopic member 1421 is arranged in the installation groove 1411 and is slidably connected to the groove wall of the installation groove 1411.

[0037] Combined with the above solutions of the mating structure 142 being in the first position and the second position, when the mating structure 142 is in the first position, at least a part of the telescopic member 1421 retracts into the installation groove 1411. Then, the lower end of the telescopic member 1421 is far from the ratchet teeth 1311, and the frictional resistance between the telescopic member 1421 and the ratchet teeth 1311 is small. At this time, the center-of-gravity adjustment part 140 can slide along the length direction of the bridging arm 130. When the mating structure 142 is in the second position, the telescopic member 1421 extends out of the installation groove 1411. Then, the lower end of the telescopic member 1421 is close to the ratchet teeth 1311 and can be engaged with one of the plurality of ratchet teeth 1311. At this time, the center-of-gravity adjustment part 140 remains relatively stationary with respect to the bridging arm 130.

[0038] In addition, asFigure 5 As shown, the engaging structure 142 may further include an elastic member 1422. The elastic member 1422 may be a metal spring, a silicone spring, etc. The elastic member 1422 is disposed in the installation groove 1411 and located between the bottom of the installation groove 1411 and the telescopic member 1421. Both ends of the elastic member 1422 are respectively abutted against the bottom of the installation groove 1411 and the telescopic member 1421. When the engaging structure 142 is in the second position, that is, when the telescopic member 1421 extends out of the installation groove 1411, the elastic member 1422 can elastically support between the telescopic member 1421 and the bottom of the installation groove 1411 and provide an elastic pre-tightening force to the telescopic member 1421, so that the telescopic member 1421 can be stably engaged with the ratchet tooth 1311.

[0039] When it is necessary to slide the center-of-gravity adjustment part 140, a force can be manually applied to the center-of-gravity adjustment part 140 to prompt it to slide along the length direction of the bridging arm 130. Under the action of the force, the inclined surface of the ratchet tooth 1311 can apply a reaction force to the telescopic member 1421 and prompt at least a part of the telescopic member 1421 to retract into the installation groove 1411, so that the sliding of the center-of-gravity adjustment part 140 can be realized. When moving to the next ratchet tooth 1311, the telescopic member 1421 extends out of the installation groove 1411 under the elastic force of the elastic member 1422 and is engaged with the ratchet tooth 1311, so that the center-of-gravity adjustment part 140 and the bridging arm 130 remain relatively stationary. When it is necessary to continue sliding the center-of-gravity adjustment part 140, the above operation can be repeated.

[0040] The first end of the telescopic member 1421 extends into the installation groove 1411. To prevent the telescopic member 1421 from disengaging from the installation groove 1411 and causing the failure of the engaging structure 142, a limit flange 1423 can be provided at the first end of the telescopic member 1421. The limit flange 1423 can be used to engage with the notch of the installation groove 1411 when the telescopic member 1421 extends out of the installation groove 1411, preventing the telescopic member 1421 from disengaging from the installation groove 1411, thereby improving the stability of the cooperation between the telescopic member 1421 and the adjustment body 141.

[0041] In addition, in order to facilitate the sliding of the center-of-gravity adjustment part 140, a chamfer 1424 can be provided at the second end of the telescopic member 1421. The chamfer 1424 can be used for guiding cooperation with the ratchet tooth 1311. When a force is manually applied to the center-of-gravity adjustment part 140, the ratchet tooth 1311 can apply a reaction force to the telescopic member 1421 through the chamfer 1424, so that at least a part of the telescopic member 1421 retracts into the installation groove 1411.

[0042] The embodiment of the present application also discloses an earphone device, which may include an earphone compartment and the above-mentioned ear-clip earphone, wherein the interior of the earphone compartment has a storage space, and the ear-clip earphone is placed in the storage space. In addition, the interior of the earphone compartment may also be provided with a rechargeable battery, which can be used to charge the ear-clip earphone. The number of ear-clip earphones included in the earphone device may be one, two, or more than two. In an optional embodiment of the present application, the earphone device may include two ear-clip earphones, corresponding to the left ear and the right ear of the wearer, respectively. Correspondingly, the interior of the earphone compartment has two storage spaces, which are respectively used to accommodate the above-mentioned two ear-clip earphones.

[0043] As described above, the ear clip earphone disclosed in the embodiment of the present application improves the related art. By setting the center of gravity adjustment part 140 on the bridging arm 130, when the sound outlet part 110 is worn too deep or too shallow inside the auricle, the center of gravity adjustment part 140 can be controlled to be in the first state, so that the center of gravity adjustment part 140 can be moved along the length direction of the bridging arm 130, so that the center of gravity of the ear clip earphone can be adjusted. When the center of gravity of the ear clip earphone changes, the forces applied to the auricle by the sound outlet part 110 and the clamping part 120 will also change accordingly, and the center of gravity of the ear clip earphone can be adjusted according to the change of the center of gravity. The center of gravity of the ear clip earphone is adjusted according to the actual wearing posture, so that the sound output part 110 and the clamping part 120 will neither over-press the auricle nor become loose, thereby making the ear clip earphone and the wearer's auricle reach a relatively comfortable and stable wearing state; after the position adjustment of the center of gravity adjustment part 140 is completed, the center of gravity adjustment part 140 can be controlled to be in the second state, so that the center of gravity adjustment part 140 and the bridging arm 130 remain relatively still, thereby avoiding the problem of frequent adjustments due to changes in the position of the center of gravity adjustment part 140 caused by shaking.

As long as the different technical features between the various embodiments are not contradictory, they can be combined to form more specific embodiments. Considering the simplicity of the text, they will not be repeated here.

Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
