Description

Technical Field

[0001] This invention relates to the field of headphones, and more particularly to headphone components and head-mounted devices. Background Technology

[0002] When wearing headphones, the earphone shell covering the ears is connected to the wearing bracket via a headphone pull-out mechanism. The earphone shell has a mounting channel for the headphone pull-out mechanism to pass through. However, users' face shapes and ear shapes are not all the same. In order to make it easier for users to adjust the relative angle between the earphone shell and the headphone pull-out mechanism so that the earphone shell can fit the user, a large gap is set between the wall of the mounting channel between the headphone pull-out mechanism and the earphone shell. This allows the headphone pull-out mechanism to make room when it swings relative to the earphone shell. However, the large gap makes the headphones look unsightly, and the excessively large gap allows noise to be transmitted into the earphone shell, thus affecting the low frequency acoustics.

[0046] When wearing headphones, the earphone shell covering the ears is connected to the wearing bracket via a headphone pull-out mechanism. The earphone shell has a mounting channel for the headphone pull-out mechanism to pass through. However, users' face shapes and ear shapes are not all the same. In order to make it easier for users to adjust the relative angle between the earphone shell and the headphone pull-out mechanism so that the earphone shell can fit the user, a large gap is set between the wall of the mounting channel between the headphone pull-out mechanism and the earphone shell. This allows the headphone pull-out mechanism to make room when it swings relative to the earphone shell. However, the large gap makes the headphones look unsightly, and the excessively large gap allows noise to be transmitted into the earphone shell, thus affecting the low frequency acoustics.

[0047] To address the aforementioned problems, the present invention provides an earphone assembly 100 for use in a head-mounted device. The head-mounted device includes two earphone assemblies 100 and a wearing bracket, wherein the two earphone assemblies 100 are respectively disposed at both ends of the wearing bracket. Figures 1 to 9 This is a specific embodiment of the headphone assembly 100 provided by the present invention.

[0048] Please see Figures 1 to 3 The headphone assembly 100 includes a headphone body 1 and an adjustment member 2. The headphone body 1 has an inner side facing the ear and an outer side away from the ear. The headphone body 1 has a mounting cavity with an upper opening, and the mounting cavity is at least partially configured as a spherical cavity. The adjustment member 2 has a first end and a second end. The first end has a ball head 21 adapted to the spherical cavity. The ball head 21 is accommodated in the spherical cavity so that the headphone body 1 can swing relative to the adjustment member 2 at least in the inward and outward directions. The second end is exposed outside the opening for connection with a wearing bracket.

[0049] In the technical solution provided by this invention, the headphone body 1 has a mounting cavity with an opening at the top. An adjusting member 2 can be inserted into the mounting cavity through the opening. The mounting cavity is at least partially configured as a spherical cavity. The adjusting member 2 has a first end and a second end. The first end has a ball head 21 adapted to the spherical cavity, which is housed within the spherical cavity. The second end protrudes outside the opening for connection with a wearing bracket. In this technical solution, the hinge between the ball head 21 and the spherical cavity on the headphone body 1 and the adjusting member 2 allows the headphone body 1 to swing relative to the adjusting member 2 in at least the inward and outward directions. No clearance space is required when the spherical cavity mates with the ball head 21, thus eliminating the need for excessively large gaps between them. After the adjusting member 2 is sealed to the headphone body, noise can be blocked and attenuated to a certain extent, reducing the noise received by the ear and achieving a better passive effect. This solves the problem of excessively large and unsightly gaps and high noise levels when existing headphones are connected to a wearing bracket.

[0050] Furthermore, in order to ensure a stable hinge between the ball head 21 and the spherical cavity, the cavity wall needs to be relatively thick to guarantee its strength. However, if the cavity wall is too thick, the mounting channel between the spherical cavity and the opening needs to be too large to allow for movement during the swing of the adjusting member 2. This still results in an excessively large gap between the adjusting member 2 and the headphone body 1, affecting aesthetics. Therefore, please refer to... Figure 4 and Figure 6In this embodiment, the headphone body 1 also forms an installation channel a connecting the spherical cavity and the opening. Since the geometric center of the spherical cavity and the ball head 21 is the rotation center of the adjusting member 2, the further away the adjusting member 2 is from the ball head 21, the greater its swing amplitude. Therefore, the installation channel a follows the swing amplitude of the adjusting member 2. The installation channel a is gradually widened in the direction close to the opening, so that the inner wall of the installation channel a is tapered. In this way, the visual effect of the installation channel a is transitional, which is better in appearance while ensuring strength.

[0051] Specifically, for ease of forming the headphone body 1, please refer to... Figure 6 In this embodiment, the headphone body 1 includes a housing 11 and a mounting portion 12. The upper end of the housing 11 forms a first channel 11a extending vertically, with an opening at the upper end of the first channel 11a. The mounting portion 12 is disposed within the housing 11. The mounting portion 12 can be screwed onto the housing 11 or snapped onto the housing 11. The mounting portion 12 forms a spherical cavity and a second channel 12a communicating with the spherical cavity. The second channel 12a is located at the upper end of the mounting portion 12 and extends vertically, corresponding to the first channel 11a to form the mounting channel a. With this configuration, the wall thickness of the housing 11 is not affected by the mounting cavity, avoiding uneven wall thickness that could lead to poor appearance.

[0052] Furthermore, since the ball head 21 is installed in the spherical cavity, the mounting part 12 is equivalent to surrounding the ball head 21. For convenient installation of the ball head 21, please refer to [link / reference needed]. Figure 6In this embodiment, the mounting portion 12 includes a first mounting portion 121 and a second mounting portion 122 spaced apart in the vertical direction. The lower side of the first mounting portion 121 is recessed with a first mounting groove 121a. The first mounting groove 121a is gradually widened in the direction of groove depth toward groove opening. The bottom wall of the first mounting groove 121a is provided with a second channel 12a. Thus, during installation, the adjusting member 2 can be inserted upward from the lower side of the first mounting portion 121 until the upper end of the ball head 21 abuts against the inner wall of the first mounting groove 121a. In order to position the lower end of the ball head 21, a second mounting groove 122a is formed in the second mounting portion 122. The groove opening of the second mounting groove 122a is set toward the groove opening of the first mounting groove 121a. The second mounting groove 122a is gradually widened in the direction of groove depth toward groove opening, so as to surround the first mounting groove 121a to form the spherical cavity. Thus, during installation, after the first mounting part 121 and the adjusting member 2 are assembled, the second mounting part 122 is then installed from the lower end of the ball head 21, so that the ball head 21 can be clamped between the first mounting part 121 and the second mounting part 122.

[0053] Further, please refer to Figure 5 In another embodiment, the headphone assembly 100 further includes a sealing gasket 3 disposed between the adjusting member 2 and the first mounting portion 121. This arrangement provides a damping feel during use, improving the tactile experience, and also provides waterproofing in rainy or other complex humidity environments.

[0054] Furthermore, to avoid unnecessary shaking of the headphone body 1, please refer to... Figures 6 to 7 In this embodiment, the headphone body 1 has a limiting channel b communicating with the spherical cavity. A limiting protrusion 211 protrudes from the outer side of the ball head. The limiting protrusion 211 is located within the limiting channel b and is used to limit the movement of the adjusting member 2 relative to the headphone body 1. The shape and position of the limiting channel b are not limited. In one embodiment, the first mounting part 121 has a recessed groove on its end face near the second mounting part 122. The bottom wall of the groove has a recessed first mounting groove 121a. The end face of the second mounting part 122 near the first mounting part 121 is spaced apart from the bottom wall of the groove. Therefore, the limiting channel b is formed between the end face of the second mounting part 122 and the bottom wall of the groove.

[0055] Furthermore, since the connection between the ball head 21 and the spherical cavity is hinged, the ball head 21 can rotate relative to the earphone body 1. To control the rotation angle of the earphone body 1, please refer to [link to relevant documentation]. Figures 8 to 9In this embodiment, the inner wall surface of the limiting channel b is provided with a limiting part 13 to limit the adjustment member 2 when it rotates relative to the headphone body part 1.

[0056] Specifically, in one embodiment, the swing angle of the earphone body 1 relative to the adjustment member 2 in the inward and outward directions is θ, where θ ≤ 12°. This swing angle is reasonably set according to the shape and size of the average human ear in ergonomics, so that the earphone assembly 100 can fully adapt to most users. In another embodiment, the first rotation angle of the earphone body 1 relative to the adjustment member 2 in a first clockwise direction is α1, where α1 ≤ 35°; and / or, the second rotation angle of the earphone body 1 relative to the adjustment member 2 in a second clockwise direction opposite to the first clockwise direction is α2, where α2 ≤ 100°. This allows the earphone body 1 to rotate at an appropriate angle to adapt to the packaging box during the later packaging of the head-mounted device, and also makes it convenient for outdoor athletes to hang the earphones around their necks for easy use.

[0057] Further, please refer to Figures 1 to 3 In this embodiment, the headphone assembly 100 further includes a reset member 4, which is connected to the headphone body 1 and the adjustment member 2 to provide a reset force when the adjustment member 2 swings relative to the headphone body 1, so that when the headphone body 1 swings to a suitable angle, the reset force of the reset member 4 can clamp the headphone body 1 to the ear and fit the user's ear.

[0058] Specifically, since the second end of the adjusting member 2 has the largest swing amplitude, in order for the reset member 4 to provide a better reset force when the earphone body 1 swings relative to the adjusting member 2, and to facilitate installation, please refer to [reference needed]. Figure 3 In this embodiment, a third channel 13a is further provided downward on the lower side of the spherical cavity. The second end has a first segment 22 that is at least partially exposed outside the third channel 13a. A limiting groove 22a is formed circumferentially on the periphery of the first segment 22. The reset member 4 includes a spring with a bent section in the middle. Both ends of the spring are connected to the headphone body 1, and the bent section is located within the limiting groove 22a. With this configuration, the first segment 22 is located outside the mounting cavity, facilitating the installation of the spring.

[0059] The present invention also provides a head-mounted device, which may be a headset or VR glasses, etc. The head-mounted device includes two headphone assemblies 100 and a wearing bracket. The two headphone assemblies 100 are respectively disposed at both ends of the wearing bracket, and each adjustment member 2 is connected to the corresponding end of the wearing bracket. Since the head-mounted device includes the headphone assembly 100, the specific structure of the headphone assembly 100 is as described in the above embodiments. Since the headphone assembly 100 of the head-mounted device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0060] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
