Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and more specifically, to a sliding arm adjustment component and a headphone. Background Technology

[0002] Over-ear headphones, with their excellent acoustic sealing and wearing stability, occupy an important position in many fields such as professional audio monitoring, audio-visual entertainment, and daily communication. The headband and the sliding arm adjustment assembly connected to it not only bear the weight of the headphones themselves, but also directly determine the fit, comfort, and adaptability to different head shapes. Currently, the mainstream over-ear headphones on the market generally use a single elastic material bent into a roughly U-shaped or arc-shaped structure for the headband design, so that the earcups can fit the sides of the user's head. However, existing over-ear headphones often have the problems of greater pressure on the ear area of ​​users with large heads and easy wear and tear on the sliding arm adjustment.

[0003] On the one hand, when the user's head size exceeds the "comfortable deformation" range of the elastic headband, in order to ensure the necessary fit and seal between the earcups and the head to maintain sound quality, the headband is forced to deform more. This excessive deformation causes a sharp increase in static pressure applied to the top of the user's head and the area near the temples on both sides, resulting in obvious discomfort.

[0004] On the other hand, after frequent extension and retraction operations, the internal positioning teeth, buckles, or friction elements of the sliding arm adjustment structure are prone to wear, deformation, or fatigue. This wear directly leads to positioning failure, causing the adjustment components of the sliding arm to fail.

[0005] Therefore, existing headphones need improvement in terms of comfort for users with larger heads and wear and tear on the sliding arm adjustment. Utility Model Content

[0006] To address the aforementioned technical problems, this invention provides a sliding arm adjustment assembly and a headset, thereby resolving the issues of excessive pressure on the ear area of ​​users with large heads and easy wear and tear on the sliding arm adjustment mechanism in existing technologies.

[0007] The purpose and function of this utility model, namely a sliding arm adjustment component and a headset, are achieved by the following specific technical means:

[0008] A sliding arm adjustment assembly includes a first earphone beam and a second earphone beam. The second earphone beam is disposed at one end of the first earphone beam. A connecting rod and two sets of friction plates are disposed between the first earphone beam and the second earphone beam. A first spring is disposed at one end of the connecting rod. Multiple sets of ventilation holes are disposed on the outer sides of the first earphone beam and the second earphone beam.

[0009] Both the first and second earphone beams are provided with sliding grooves, each set of sliding grooves is provided with two sets of retaining strips, each set of sliding grooves is provided with a sliding arm, each set of sliding arms is connected to a slider at one end, and each set of sliders is provided with two sets of second springs and two sets of limiting members at one end.

[0010] According to a preferred embodiment, the first earphone beam has three sets of first connecting rings at one end near the second earphone beam, and the second earphone beam has two sets of second connecting rings at one end near the first earphone beam, with both sets of second connecting rings being engaged between the three sets of first connecting rings.

[0011] According to a preferred embodiment, each of the three sets of first connecting rings and the two sets of second connecting rings has a connecting hole on one side. The same set of connecting rods passes through the multiple sets of connecting holes. Two sets of friction plates are connected to the connecting rods. One side of each of the two sets of friction plates contacts the two sets of second connecting rings respectively. A spring is fixedly connected to one end of the connecting rod, and one end of the spring contacts one of the sets of first connecting rings.

[0012] According to a preferred embodiment, the four sets of locking strips are respectively locked onto both sides of the two sets of sliding grooves, and the sliding arms are locked in the two sets of sliding grooves. The two sets of sliding arms are respectively locked onto one end of the two sets of sliding blocks.

[0013] According to a preferred embodiment, mounting holes are provided on both sides of the two sets of sliders, and springs and limiting members are provided in the four sets of mounting holes. One end of each of the four sets of limiting members is fixedly connected to the spring, and the other end of each of the four sets of limiting members is in contact with the locking strip.

[0014] According to a preferred embodiment, multiple sets of ventilation holes are provided through the outer sides of both the first and second earphone beams, and the multiple sets of ventilation holes are evenly distributed around the periphery of the first and second earphone beams. Hollow holes are provided on both sets of sliding arms.

[0015] According to a preferred embodiment, each of the two sets of sliding arms is provided with a locking block and a connecting member at one end, and each of the two sets of connecting members is connected to the sliding arm through the locking block, and each of the two sets of connecting members is provided with a connecting block at the bottom.

[0016] A type of over-ear headphone includes an earphone body, wherein a sliding arm adjustment assembly is provided on the top of the earphone body.

[0017] Based on the above aspects, the embodiments of this application achieve the following:

[0018] 1. For users with larger heads, the user can press one end of the connecting rod to compress the first spring. At this time, the two sets of friction plates will disengage from the surface of the second connecting ring. The user can rotate to adjust the angle of the first and second earphone beams. At the same time, both the first and second earphone beams have a certain degree of elasticity, allowing the user to freely adjust the width of the earphones. This prevents a single earphone beam from putting too much pressure on the area around the ears of users with larger heads due to excessive elasticity, thus avoiding discomfort.

[0019] 2. When adjusting the sliding arm, the user grasps the headphone body and pulls the sliding arm out of the sliding groove. The limiting member is pushed into the mounting hole by the protrusion of the retaining strip. At this time, the sliding arm can slide along the sliding groove. After adjusting to the appropriate position, the user releases the headphone body, and the spring pushes the limiting member back into the groove of the retaining strip, fixing the sliding arm. This allows for quick adjustment of the headphone body position, improving the ease of adjustment of the headphones. The end of the limiting member that contacts the retaining strip is rounded to reduce friction with the retaining strip, improving the durability of the headphones. Multiple sets of ventilation holes are provided on both the first and second headphone beams to improve the breathability at the point where the first and second headphone beams fit against the user's head, making it less likely for the user's head to feel stuffy, thus improving the practicality of the headphones.

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0028] As attached Figure 1 To be continued Figure 5 As shown:

[0029] A sliding arm adjustment assembly includes a first earphone beam 100 and a second earphone beam 101 as its core components. The second earphone beam 101 is tightly disposed at one end of the first earphone beam 100, and the two cooperate to form the basic structure of the earphone beam. A connecting rod 102 and two sets of friction plates 103 are installed between the first earphone beam 100 and the second earphone beam 101. One end of the connecting rod 102 is fixedly connected to a first spring 104. Multiple sets of ventilation holes 105 are evenly distributed on the outer sides of the first earphone beam 100 and the second earphone beam 101. These ventilation holes 105 can increase the breathability of the earphone beam and improve the comfort when wearing it.

[0030] Inside the first headphone beam 100 and the second headphone beam 101, there are sliding grooves 106. In each of the two sets of sliding grooves 106, there are two sets of retaining strips 107. The presence of retaining strips 107 serves to limit the sliding of the sliding arm 108 and the slider 109 in the sliding grooves 106. The sliding arm 108 is installed in the sliding groove 106, and one end of it is connected to the slider 109. One end of the slider 109 is provided with two sets of second springs 110 and two sets of limiting members 111. The second springs 110 and the limiting members 111 cooperate with each other. One end of the limiting member 111 is inserted into the groove of the retaining strip 107, so that the slider 109 and the sliding arm 108 are restricted.

[0031] The first headphone beam 100 has three sets of first connecting rings 112 near the end of the second headphone beam 101, and the second headphone beam 101 has two sets of second connecting rings 113 near the end of the first headphone beam 100. The two sets of second connecting rings 113 are engaged between the three sets of first connecting rings 112 to form a rotatable connection structure.

[0032] Each of the three sets of first connecting rings 112 and the two sets of second connecting rings 113 has a connecting hole 114 on one side. A connecting rod 102 passes through multiple connecting holes 114. Two sets of friction plates 103 are connected to the connecting rod 102. One side of each friction plate 103 is in close contact with one of the two sets of second connecting rings 113. The friction plates 103 increase the friction between the first headphone beam 100 and the second headphone beam 101, making it less likely for the first headphone beam 100 and the second headphone beam 101 to rotate relative to each other. A first spring 104 is fixedly connected to one end of the connecting rod 102. The other end contacts one of the first connecting rings 112. The first spring 104 plays the role of resetting the connecting rod 102 during the adjustment of the headphone beam. When a user with a larger head uses the headphones, the end of the connecting rod 102 away from the first spring 104 can be pressed down, and the friction plate 103 will disengage from the surface of the second connecting ring 113, so that the first headphone beam 100 and the second headphone beam 101 can be rotated to adjust the angle to adapt to users with different head sizes. This prevents the single headphone beam from putting too much pressure on the area around the ears of users with larger heads due to excessive elasticity, thus preventing discomfort to the user.

[0033] Four sets of locking strips 107 are respectively locked onto both sides of two sets of sliding grooves 106. The sliding arms 108 locked in the two sets of sliding grooves 106 have two sets of sliders 109 locked at one end. The locking of the sliders 109 and the sliding arms 108 allows the sliding arms 108 to slide smoothly in the sliding grooves 106 through the sliders 109.

[0034] Both sides of the two sets of sliders 109 are provided with mounting holes 115. A second spring 110 and a limiting member 111 are respectively installed in each of the four sets of mounting holes 115. One end of each limiting member 111 is fixedly connected to the second spring 110, and the other end contacts the retaining strip 107. When the sliding arm 108 drives the slider 109 to slide, the second spring 110 and the limiting member 111 can extend, retract, and limit the movement according to the sliding position, ensuring that the sliding arm 108 will not easily disengage from the sliding groove 106 during adjustment. This ensures the safety and stability of the adjustment. When the user adjusts the sliding arm 108, they only need to grasp the headphone body 120 and pull it away from the sliding groove 106. At this time, the limiting member 111 will be pushed back into the mounting hole 115 by the protrusion of the locking strip 107, and the spring will be compressed. When the user adjusts the sliding arm 108 to the appropriate position, the spring will push the limiting member 111 back into the groove of the locking strip 107, and the slider 109 and the sliding arm 108 will be fixed. The user can quickly adjust the sliding arm 108, which is convenient and fast.

[0035] Multiple sets of ventilation holes 105 are provided on the outer sides of the first headphone headband 100 and the second headphone headband 101. These ventilation holes 105 are evenly distributed around the periphery of the first headphone headband 100 and the second headphone headband 101, which can effectively promote air circulation and reduce the stuffiness of the head when wearing headphones. At the same time, hollow holes 116 are provided on both sets of sliding arms 108. The hollow holes 116 further reduce the weight of the sliding arms 108 and also help air circulation to a certain extent.

[0036] Each of the two sets of sliding arms 108 has a locking block 117 and a connector 118 at one end. Both sets of connectors 118 are firmly connected to the sliding arms 108 through the locking block 117. This connection method ensures the stability between the connectors 118 and the sliding arms 108. Each of the two sets of connectors 118 has a connecting block 119 at the bottom. The connecting block 119 can be used to connect with the headphone body 120 to realize the combination of the sliding arm adjustment component and the headphone body 120.

[0037] A type of over-ear headphone includes an earphone body 120 as an important component. The aforementioned sliding arm adjustment assembly is installed on the top of the earphone body 120. Through the sliding arm adjustment assembly, the user can flexibly adjust the position of the two sets of earphone bodies 120 according to their own head size, thereby obtaining a comfortable wearing experience. At the same time, the various parts of the sliding arm adjustment assembly cooperate with each other to ensure the structural stability and durability of the over-ear headphone during use.

[0038] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
