[0071] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0072] When using over-ear headphones, the headphones are worn on the head and the earcups cover the ears, providing better sound isolation and noise reduction.

[0073] In related technologies, over-ear headphones have a limited usage method. Due to poor air circulation inside the earcups, prolonged wear can easily lead to stuffiness, sweating, and discomfort in the ears. Moreover, in order to ensure sound isolation, the earcups exert pressure on the ears, which can easily cause pressure and fatigue during prolonged wear.

[0074] Furthermore, the closed acoustic space of earcups restricts the natural diffusion and reflection of sound, resulting in a less open soundstage and less natural sound compared to open-back headphones. The sound is more "closed," lacking the natural and spacious listening experience of open-back headphones, and its performance is insufficient when enjoying classical, symphonic, and other music genres that require a wide soundstage. In addition, closed-back earcups isolate external sounds when worn, making it difficult to hear car horns or pedestrian conversations when wearing them in the street, thus posing a safety concern.

[0075] To address this, this application provides an embodiment of a headset with a hollow design that enhances comfort when worn. By incorporating a rotating structure, the speaker can be positioned either facing inwards for a head-wearing mode or outwards for an external playback mode, thereby increasing the flexibility of the headset's usage mode and avoiding discomfort caused by prolonged use in a single head-wearing mode.

[0076] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0077] First, it needs to be explained that the headphones in this embodiment can be worn on the head. The basic axes of the human body include a vertical axis, a sagittal axis, and a frontal axis, all of which are perpendicular to each other. The vertical axis is oriented up and down, consistent with the direction of gravity when the human body is upright. The sagittal axis is oriented forward and backward, and the frontal axis is oriented left and right.

[0078] Combination Figure 1 , Figure 2 as well as Figure 3 This application provides a headset, which includes a headband 100 and two earphone bodies 200, the two earphone bodies 200 being respectively connected to both ends of the headband 100.

[0079] The headband 100 is arc-shaped to fit the wearer's head. The headband 100 can be a fixed-length arc-shaped beam with a simple structure. Alternatively, the headband 100 can be a telescopic beam that extends and retracts along the arc-shaped extension direction, facilitating length adjustment. The inner side of the headband 100 is the concave side that contacts the head; the outer side of the headband 100 is the convex side.

[0080] The headphone body 200 includes an earcup portion 210 and a sound-emitting portion 220, with the earcup portion 210 connected to the headband portion 100. The earcup portion 210 can be directly connected to the headband portion 100, or it can be indirectly connected to the headband portion 100 via an intermediate connecting structure. Exemplarily, in this embodiment, the earcup portion 210 is connected to the headband portion 100 via a bracket 300.

[0081] The earcup portion 210 contacts the wearer's ear, and the side of the earcup portion 210 facing the ear may be provided with a flexible structure such as sponge. The earcup portion 210 has opposing inner and outer surfaces, with the inner surface of the earcup portion 210 facing the wearer's ear and contacting the ear. The outer surface of the earcup portion 210 faces away from the wearer's head. Whether the edge of the earcup portion 210 covers the auricle of the ear is not limited in this embodiment.

[0082] The shape of the earcup portion 210 can be circular, oval, or rounded rectangle, or other irregular smooth shape, without any limitation.

[0083] In this embodiment, the earcup portion 210 is configured to form a hollow cavity, that is, the earcup portion 210 is annular, and the earcup portion 210 has an inner annular surface and an outer annular surface. The inner annular surface is the annular surface that forms the hollow cavity on the inner side, and the outer annular surface is the annular surface on the outer side.

[0084] The hollow cavity is a through cavity, allowing part of the wearer's ear inside the earcup 210 to be exposed through the hollow cavity.

[0085] The sound-emitting part 220 is used to emit sound signals. The sound-emitting part 220 is located inside the annular ear cup part 210, that is, the sound-emitting part 220 is located inside the hollow cavity, and there is a gap between the sound-emitting part 220 and the inner ring surface of the ear cup part 210, forming a hollow area 211 so that part of the wearer's ear is exposed.

[0086] A front acoustic cavity 201 and a rear acoustic cavity 202 are formed between the sound-emitting part 220 and the ear cup part 210, wherein the front acoustic cavity 201 and the rear acoustic cavity 202 are located on opposite sides of the sound-emitting part 220. When worn, the front acoustic cavity 201 can face the ear, and the rear acoustic cavity 202 can face away from the ear.

[0087] The front acoustic cavity 201 and the rear acoustic cavity 202 are connected to form a hollow structure, allowing the part of the wearer's ear to be exposed and breathable.

[0088] Thus, the earcup 210 surrounds the outer side of the sound-emitting part 220, forming a surrounding effect that helps sound waves travel towards the wearer's ear, providing a certain degree of sound insulation and improving sound quality. Furthermore, the sound-emitting part 220 does not completely fill the hollow cavity, but only occupies a portion of it, creating a hollow area 211 between the sound-emitting part 220 and the inner ring surface of the earcup 210. The front sound cavity 201 and the rear sound cavity 202 are connected through this hollow area 211, exposing part of the wearer's ear. This reduces pressure on the ear, improving wearing comfort, and the open design also allows the wearer to hear external sounds, enhancing safety.

[0089] The headphones of this application embodiment, while maintaining the traditional wearing method, improve wearing comfort by setting a hollow area 211 in the middle, so that the ear part can be opened through the hollow area 211.

[0090] The sound-emitting unit 220 of this embodiment has an external speaker mode and a headphone mode. The sound-emitting unit 220 is configured to output sound to the wearer's ear in a headphone mode when worn, and to output sound to the external space in an external speaker mode when not worn, and can switch between the headphone mode and the external speaker mode. When the headphones are worn on the ears, the sound-emitting unit 220 operates in headphone mode; when the headphones are in an external speaker mode, the sound-emitting unit 220 operates in external speaker mode.

[0091] The sound-emitting part 220 may include a housing and a speaker disposed within the housing, which can operate in either headphone mode or external speaker mode.

[0092] Combination Figure 1 and Figure 3 The sound-emitting part 220 is rotatably connected to the earcup part 210 so that the sound-emitting part 220 can rotate between the head-mounted position and the external speaker position.

[0093] Reference Figure 4 When the speaker unit 220 is in the headband position, it operates in headphone mode. (See reference...) Figure 5 When the speaker unit 220 is in the external speaker position, it operates in external speaker mode. Specifically, in... Figure 5 In China, over-ear headphones can be worn around the neck. Of course, this does not restrict the way over-ear headphones are used for playing music.

[0094] like Figure 4 As shown, the sound-emitting part 220 is provided with a sound outlet 221, which faces the speaker of the sound-emitting part 220, so that the speaker can transmit sound outward. When the sound-emitting part 220 is in the head-wearing position, the sound outlet 221 faces the wearer's ear. At this time, the sound outlet 221 faces the inside of the head-wearing part 100.

[0095] When the speaker 220 rotates from the headband position relative to the earcup 210 to a preset position, the earcup 210 is in the external speaker position, and the headphones are in a non-wearing state. The rotation angle of the earcup 210 from the headband position to the preset position can be 0° to 180°. Due to the presence of the hollow area 211, the speaker 220 can be in the external speaker mode whether it is in the headband position or rotated at any angle relative to the headband position.

[0096] When the earcup 210 rotates 180° from the headband position to the preset position, the sound outlet 221 faces the outer side of the headband 100, as shown below. Figure 5 As shown.

[0097] In this embodiment, the earcup portion 210 rotates 180° from the headband position to the preset position, so that the sound outlet 221 faces the outside of the headband portion 100, which is more conducive to the propagation of sound waves in the open space and improves the external sound effect.

[0098] Therefore, the sound-emitting part 220 of this embodiment has a headphone mode and a speaker mode. Utilizing the rotatable connection between the sound-emitting part 220 and the earcup part 210, the sound-emitting part 220 can rotate between a head-mounted position and a speaker position. In the head-mounted position, the sound outlet 221 of the sound-emitting part 220 faces the wearer's ear, thus achieving headphone mode. This allows sound waves to enter the ear at a closer distance, facilitating sound propagation and achieving relatively closed audio reception in head-mounted mode, reducing noise issues caused by the hollow area 211 and ensuring sound quality. Rotating the sound-emitting part 220 from the head-mounted position to the speaker position enables speaker mode, expanding the usage modes of the headphones, avoiding the pressure of continuous wear, and allowing users to flexibly choose the usage mode.

[0099] In this embodiment, the sound-emitting part 220 rotates relative to the earcup part 210 to adjust the orientation of the sound outlet 221, thereby switching between a head-mounted position and a speaker position. Users can select between head-mounted mode and speaker mode based on audio type, increasing the product's functionality.

[0100] In some embodiments, the hollow cavity is a circular cavity, and the axis of the hollow cavity may be parallel to the frontal axis of the human body. The cross-sectional shape of the hollow cavity is circular, with a regular structure and good appearance; moreover, it is relatively easy to clean and maintain.

[0101] The earcup portion 210 can be circular, which makes the radial dimension of the earcup portion 210 more uniform, which helps to improve the uniformity of the force exerted by the earcup portion 210 on the ear, thereby helping to improve the wearing comfort.

[0102] Combination Figure 6 The sound-emitting part 220 is circular in its orthographic projection onto the first plane, which is perpendicular to the axis of the hollow cavity. The first plane can be... Figure 6 In the XY plane, the first plane is parallel to the plane defined by the sagittal axis and the vertical axis. The circular shape of the sound-emitting part 220 matches the circular hollow cavity, which not only improves the appearance but also makes the hollow area 211 relatively regular.

[0103] When the headphones are worn on the ears, the sound-producing part 220 is positioned forward and off-center relative to the hollow cavity.

[0104] This can be understood as the center of the sound-emitting part 220 not coinciding with the center of the hollow cavity, causing the center of the sound-emitting part 220 to deviate from the center of the hollow cavity. When the headphones are worn on the ears, the area in front of the wearer is "front" and the area behind is "back".

[0105] This design reduces pressure on the helix, and the 220mm forward-biased position of the sound-producing part, located in front of the helix and closer to the ear canal, is more conducive to sound pickup.

[0106] Combination Figures 6 to 8 In some embodiments of this application, the sound-emitting part 220 and the earcup part 210 are connected by a first rotating shaft 240. The first rotating shaft 240 may be disposed on the sound-emitting part 220, and correspondingly, the earcup part 210 is provided with a connecting hole 212 that mates with the first rotating shaft 240. Alternatively, the first rotating shaft 240 may be disposed on the earcup part 210, and correspondingly, the sound-emitting part 220 is provided with a connecting hole 212 that mates with the first rotating shaft 240.

[0107] When the headphones are worn on the ears, the first pivot 240 is parallel to the vector axis of the human body. The extension direction of the first pivot 240 can correspond to... Figure 6 D1 direction.

[0108] The openwork area 211 is roughly C-shaped, similar to the shape of the auricle, which helps improve the evenness of ventilation in the exposed parts of the ear and reduces discomfort caused by excessive local pressure. Combined with... Figure 5 Along the circumference of the earcup portion 210, from the front end to the rear end of the sound-emitting portion 220, the interval between the outer surface of the sound-emitting portion 220 and the inner ring surface gradually increases, that is, the radial dimension of the hollow area 211 gradually increases.

[0109] With this configuration, the sound-emitting part 220 can rotate relative to the first rotating shaft 240. The two ends of the first rotating shaft 240 are evenly subjected to gravity, making the rotation of the sound-emitting part 220 smoother. Moreover, the first rotating shaft 240, which is arranged vertically relative to the vector axis, allows the sound-emitting part 220 to be adjusted up and down, making it fit the auricle better and reducing pressure on the ear or sound leakage.

[0110] Furthermore, the sound-emitting part 220 is offset forward relative to the earcup part 210, allowing the front part of the first pivot 240 to be hidden in the earcup part 210, which improves the appearance of the headphones. It does not affect the rotation of the sound-emitting part 220, and it also allows the sound-emitting part 220 to be as close as possible to the front of the earcup part 210 to match the position of the ear canal and improve the sound pickup effect. It also allows the sound-emitting part 220 to have a certain coverage around the ear canal, thereby improving the sound sealing effect in headphone mode and reducing noise problems caused by the hollow design.

[0111] In some embodiments of this application, when the headphones are worn on the ears, the thickness of the rear end of the earcup portion 210 is greater than the thickness of the front end. The thickness of the earcup portion 210 is the dimension of the earcup portion 210 along the axial direction of the hollow cavity. This arrangement allows for a larger space at the rear end of the earcup portion 210 to accommodate the electrical components of the headphones. Furthermore, the larger space at the rear end of the earcup portion 210, combined with the forward-eccentric arrangement of the sound-emitting portion 220, achieves weight balance in the headphone body 200, contributing to improved stability when wearing the headphones.

[0112] Continue to refer to Figure 6 In this embodiment of the application, the first rotating shaft 240 includes a first shaft portion 241 and a second shaft portion 242, wherein the axial length of the first shaft portion 241 is greater than the axial length of the second shaft portion 242.

[0113] When the headphones are worn on the ears, the first shaft portion 241 is located behind the sound-emitting portion 220, and the second shaft portion 242 is located in front of the sound-emitting portion 220.

[0114] The first shaft portion 241 and the second shaft portion 242 are fixedly connected to the sound-emitting portion 220, and the first shaft portion 241 and the second shaft portion 242 are rotatably connected to the earcup portion 210. The earcup portion 210 has connecting holes 212 at both ends along the horizontal diameter direction, so that the first shaft portion 241 and the second shaft portion 242 can rotate relative to the earcup portion 210.

[0115] Continue to refer to Figure 8 The earcup portion 210 includes a first half-shell 213 and a second half-shell 214, both of which are annular. The first half-shell 213 and the second half-shell 214 are fixedly connected to form the earcup portion 210. For example, the first half-shell 213 and the second half-shell 214 are snap-fitted together, a simple and reliable connection method. The space enclosed by the first half-shell 213 and the second half-shell 214 can be used to arrange electrical components such as circuit boards and batteries.

[0116] The first half-shell 213 is provided with a first half-hole 2121, and the second half-shell 214 is provided with a second half-hole 2122. When the first half-shell 213 and the second half-shell 214 are fixedly connected, the first half-hole 2121 and the second half-hole 2122 surround each other to form a connecting hole 212.

[0117] The first rotating shaft 240 of this embodiment has two shaft sections, so that both the front and rear sides of the sound-emitting part 220 are rotatably connected to the earcup part 210 through the shaft sections, which helps to improve the reliability and stability of the connection between the sound-emitting part 220 and the earcup part 210. Moreover, the axial length of the second shaft section 242 on the front side is shorter, which helps to make the sound-emitting part 220 eccentrically arranged forward relative to the earcup part 210.

[0118] Reference Figures 8 to 10 In some embodiments of this application, an elastic limiting member 215 and a mating shaft portion 243 are provided between one end of the first rotating shaft 240 and the ear cup portion 210, and the mating shaft portion 243 rotates relative to the elastic limiting member 215.

[0119] The shaft portion 243 is provided with a first limiting groove 2431 and a second limiting groove 2432; when the sound-emitting portion 220 is in the head-wearing position, the first limiting groove 2431 cooperates with the elastic limiting member 215; when the sound-emitting portion 220 is in the external position, the second limiting groove 2432 cooperates with the elastic limiting member 215.

[0120] When the first rotating shaft 240 includes a first shaft portion 241 and a second shaft portion 242, a limiting elastic member and a mating shaft portion 243 are provided between one of the first shaft portion 241 and the second shaft portion 242 and the ear cup portion 210. In this embodiment, the example of providing a limiting elastic member and a mating shaft portion 243 between the ends of the first shaft portion 241 and the ear cup portion 210 will be described.

[0121] The end of the first shaft portion 241 opposite to the sound-generating portion 220 forms a mating shaft portion 243. The diameter of the mating shaft portion 243 can be larger than the diameter of the first shaft portion 241, providing arrangement space for the first limiting groove 2431 and the second limiting groove 2432. The mating shaft portion 243 is located inside the ear cup portion 210, so that the mating of the mating shaft portion 243 and the elastic limiting member 215 is not exposed.

[0122] The limiting elastic element can be an elastic sheet structure. The limiting elastic element can include a U-shaped arm, one side arm of which is fixed to the first half shell 213 of the ear cup portion 210, and the other side arm is bent outward away from the middle area of ​​the U-shaped arm to form a limiting part, which cooperates with the first limiting groove 2431 or the second limiting groove 2432.

[0123] The arc surface of the mating shaft 243 includes a first arc surface 2433 and a second arc surface 2434. The diameter of the first arc surface 2433 is larger than the diameter of the second arc surface 2434, thereby forming a first limiting groove 2431 and a second limiting groove 2432 at the two points where the first arc surface 2433 and the second arc surface 2434 intersect.

[0124] The first limiting groove 2431 and the second limiting groove 2432 can be recessed relative to the second arc-shaped surface 2434 toward the center of the mating shaft portion 243, thereby improving the stability of the limiting elastic member mating with the first limiting groove 2431 and the second limiting groove 2432 respectively, thereby improving the stability of the sound-generating portion 220 in the head-mounted position and the external playback position.

[0125] When the first rotating shaft 240 rotates, the limiting part of the elastic limiting member 215 rotates in the second arc-shaped surface 2434, and rotates between the first limiting groove 2431 and the second limiting groove 2432, so that the limiting elastic member does not affect the rotation of the first rotating shaft 240.

[0126] In some embodiments, the first limiting groove 2431 and the second limiting groove 2432 are opposite each other along the diameter direction of the mating shaft portion 243, such that the first limiting groove 2431 and the second limiting groove 2432 are 180° apart along the circumferential direction of the mating shaft portion 243. Thus, the first rotating shaft 240 can be rotated 180° to achieve adjustment between the head-mounted position and the external position.

[0127] like Figure 9 As shown, at this time, the first limiting groove 2431 cooperates with the elastic limiting member 215, so that the sound-generating part 220 can be stably positioned in the headband position. The first rotating shaft 240... Figure 9 The headband position was rotated 180° clockwise to Figure 10 The external placement within. For example... Figure 10 As shown, at this time, the second limiting groove 2432 cooperates with the elastic limiting member 215, so that the sound-emitting part 220 can be stably in the external position. The first rotating shaft 240 from Figure 10 Rotate the external speaker position counterclockwise 180° to Figure 9 The position of the headgear in the middle.

[0128] In this embodiment, by providing a limiting elastic member and a cooperating shaft 243 between the first rotating shaft 240 and the earcup portion 210, and by providing a first limiting groove 2431 and a second limiting groove 2432 in the cooperating shaft 243, the sound-emitting portion 220 can be stably positioned in the head-mounted position and the external speaker position by utilizing the cooperation between the limiting elastic member and the first limiting groove 2431 and the second limiting groove 2432, thus preventing the sound-emitting portion 220 from rotating arbitrarily and affecting the stability of its use.

[0129] Of course, the above is merely a schematic illustration of the rotational limitation between the sound-emitting part 220 and the earcup part 210. By limiting the headband position and the external speaker position through the first limiting groove 2431 and the second limiting groove 2432, the sound-emitting part 220 can only be adjusted between the headband position and the external speaker position, making the adjustment simple and eliminating the need for repeated adjustments. In other possible implementations, multiple limiting grooves, such as three or four, can be provided in conjunction with the shaft part 243, allowing the sound-emitting part 220 to have multiple external speaker positions, making the adjustment of the sound-emitting part 220 more flexible. Alternatively, in some embodiments, the first shaft part 241 and the second shaft part 242 can also be damping shafts, allowing the sound-emitting part 220 to rotate to any position relative to the earcup part 210 and stabilize at that position, further enhancing the flexibility of the adjustment of the sound-emitting part 220.

[0130] Reference Figure 11 and Figure 12 In some embodiments, a trigger 2441 and a position sensor 216 are provided between the other end of the first rotating shaft 240 and the earcup portion 210, and the trigger 2441 and the position sensor 216 rotate relative to each other.

[0131] When the speaker 220 is in the external speaker position, the position sensor 216 is configured to be triggered by the trigger 2441 to send an external speaker mode start signal.

[0132] When the first rotating shaft 240 includes a first shaft portion 241 and a second shaft portion 242, a trigger 2441 and a position sensor 216 are disposed between the other of the first shaft portion 241 and the earcup portion 210. In this embodiment, the example of a trigger 2441 and a position sensor 216 disposed between the end of the second shaft portion 242 and the earcup portion 210 will be described.

[0133] The end of the second shaft portion 242 opposite to the sound-emitting portion 220 forms a mounting shaft portion 244. The diameter of the mounting shaft portion 244 can be larger than the diameter of the second shaft portion 242, providing a position for the installation of the trigger member 2441. The mounting shaft portion 244 is located inside the earcup portion 210, so that the engagement between the trigger member 2441 and the position sensor 216 is not exposed.

[0134] In some embodiments, the second shaft portion 242 and the mounting shaft portion 244 are provided with coaxially arranged wire holes so that the cable in the sound-generating portion 220 can be passed through the wire holes and electrically connected to the electrical components in the earcup portion 210.

[0135] The trigger element 2441 is mounted on the mounting shaft portion 244, and the position sensor 216 is mounted on the earcup portion 210. (Combined) Figure 11 The speaker 220 is located in the headband position. The trigger 2441 is 180° away from the position sensor 216. If the position sensor 216 is not triggered by the trigger 2441 to emit an external speaker mode activation signal, the default is low-power headband mode; combined with Figure 12 The sound-emitting part 220 is located in the external speaker position. The trigger 2441 is close to the position sensor 216, so that the trigger 2441 triggers the position sensor 216 to send an external speaker mode start signal, so that the external speaker mode can be activated.

[0136] For example, the trigger 2441 is a magnet, and the position sensor 216 is a Hall sensor. The structure is relatively simple, with non-contact detection and no wear.

[0137] In some other embodiments, the position sensor 216 can also be a micro switch. When the first rotating shaft 240 rotates to the external speaker position, the trigger 2441 triggers the micro switch to close, sending an external speaker mode start signal. The position sensor 216 can also be other types of proximity sensors, which are not limited in this application embodiment.

[0138] In this embodiment of the application, by providing a trigger 2441 and a position sensor 216 between the first rotating shaft 240 and the earcup portion 210, the position sensor 216 can be triggered by the trigger 2441 in the external playback position to send an external playback mode start signal, so that the high-power external playback mode can be started, avoiding the external playback mode being started in the headband position, which would produce excessively loud and harsh sound.

[0139] In some embodiments of this application, the earcup portion 210 is rotatably connected relative to the headband portion 100. When the headphones are worn on the ears, the earcup portion 210 is configured to rotate relative to the headband portion 100 about the frontal axis of the human body.

[0140] like Figure 13 As shown, the earcup portion 210 is in the initial position; as Figure 14The earcup portion 210 can be relative to Figure 13 Rotate forward from the center position; combine Figure 15 The earcup portion 210 can be relative to Figure 13 Rotate backward from the middle position. Figures 13 to 15 The positive direction of the X-axis represents the orientation "forward," and the negative direction of the X-axis represents the orientation "backward." In some embodiments, after the earcup portion 210 rotates backward by a certain angle, such as... Figure 16 As shown, the headband 100 can be placed on a supporting surface 400, and the headband 100 supports the earcups 210 and suspends them relative to the supporting surface 400. The supporting surface 400 can be a tabletop, desk, or similar surface. This allows the second speaker of the earcups 210 to have better sound propagation.

[0141] This can be understood as the headphones not being worn on the ears continuously when the earcups 210 rotate relative to the headband 100 around the frontal axis of the human body. The phrase "when the headphones are worn on the ears" only indicates the direction of rotation of the earcups 210. This direction of rotation differs from the inward / outward rotation of the earcups 210 relative to the headband 100 around the sagittal axis of the human body when the headphones are worn on the ears.

[0142] In some embodiments, the earcup portion 210 can be directly rotatably connected to the headband portion 100. For example, the earcup portion 210 and the headband portion 100 can be rotatably connected by means of a rotating shaft and a shaft hole 141.

[0143] In other embodiments, the earcup portion 210 may also be rotatable relative to the headband portion 100 via an intermediate structure.

[0144] In this embodiment, the earcup portion 210 is rotated relative to the headband portion 100 in the frontal direction around the frontal axis of the human body to adjust the angle of the earcup portion 210 relative to the headband portion 100. This can adjust the wearing angle of the earcup portion 210 to make wearing more comfortable, and can also adjust the sound output angle of the speaker portion 220 in the external playback mode to improve the external playback effect.

[0145] Reference Figure 13 The headphones also include two supports 300, and two sound-emitting parts 220 are respectively connected to the headband 100 through the two supports 300;

[0146] The bracket 300 is connected to the earcup portion 210. The bracket 300 is connected to the headband portion 100 and rotates back and forth around the frontal axis of the human body, thereby enabling the earcup portion 210 to rotate back and forth relative to the headband portion 100.

[0147] In this embodiment, by providing a bracket 300, the earcup portion 210 is directly and rotatably connected to the headband portion 100. This allows for both front-to-back rotation of the earcup portion 210 and inward / outward rotation of the earcup portion 210 relative to the headband portion 100, improving the flexibility of earcup portion 210 posture adjustment and simplifying the structure. Furthermore, the rotatable connection between the bracket 300 and the headband portion 100 facilitates flexible adjustment of the earcup portion 210's position and makes it easy to store.

[0148] For example, the bracket 300 is rotatably connected to the earcup portion 210, and the rotatable connection axis between the bracket 300 and the earcup portion 210 extends along the frontal axis, corresponding to the horizontal direction. Figure 6 In the D1 direction. Thus, the bottom ends of the two earcups 210 can rotate toward the inside of the headband 100, or the bottom ends of the two earcups 210 can rotate toward the outside of the headband 100, which can adjust the wearing angle and also provide a storage method.

[0149] Combination Figure 17 The bracket 300 includes: an arc-shaped arm 310, a connecting arm 320, and a rotating connecting part 330;

[0150] An arc-shaped arm 310 extends circumferentially around the earcup portion 210. The arc-shaped arm 310 has a first end and a second end along its extending direction. The first end of the arc-shaped arm 310 is connected to the earcup portion 210, and the second end of the arc-shaped arm 310 is connected to the connecting arm 320. Exemplarily, the first end of the arc-shaped arm 310 is rotatably connected to the earcup portion 210.

[0151] In some embodiments, the arc arm 310 can be a quarter-arc arm, i.e., a quadrant arc arm. The first end of the arc arm 310 is rotatably connected to the earcup portion 210. The arc arm 310 can be located on the rear side of the earcup portion 210 to balance the eccentrically positioned front-mounted sound-emitting part 220, making the gravity of the earcup portion 210 more balanced in the front-back direction, which is beneficial to improving the stability of wearing.

[0152] In other embodiments, the arc-shaped arm 310 may be composed of two quadrant arc-shaped arms, forming a half-arc arm, i.e., a semi-circular arc arm. In this case, the middle of the semi-circular arc arm is connected to the connecting arm 320, the semi-circular arc arm extends along the upper semicircle of the earcup portion 210, and the two ends of the semi-circular arc arm are respectively rotatably connected to the earcup portion 210, thereby improving the stability of the earcup portion 210 relative to the support 300.

[0153] One end of the connecting arm 320 away from the arc-shaped arm 310 is fixedly connected to the rotating connecting part 330; the rotating connecting part 330 is rotatably connected to the headgear 100.

[0154] For example, the arc-shaped arm 310, the connecting arm 320, and the rotating connecting part 330 are integrally formed as a single piece, resulting in a stable structure.

[0155] In this embodiment, the bracket 300, by providing an arc-shaped arm 310, can not only connect with the earcup portion 210, but also fit snugly to the earcup portion 210, which is beneficial to improving the appearance; by providing a connecting arm 320, the rotating connecting portion 330 is spaced from the earcup portion 210, so that the earcup portion 210 has sufficient space to rotate back and forth relative to the headband portion 100.

[0156] Reference Figure 13 At the initial position of the earcup portion 210, the connecting arm 320 extends along the extending direction of the headband portion 100. That is, the connecting arm 320 is located in the arcuate extending direction of the headband portion 100. Figures 13 to 15 In the diagram, the positive direction of the X-axis represents the "front" direction, and the negative direction of the X-axis represents the "back" direction.

[0157] Reference Figure 14 The earcup portion 210 is configured to rotate forward relative to the headband portion 100 around the forehead axis of the human body from its initial position to adjust the wearing angle. The rotating connection portion 330 rotates forward relative to the headband portion 100 from its initial position around the forehead axis of the human body to adjust the fitting angle of the earcup portion 210, so that the inner side of the sound-emitting portion 220 fits more closely to the area around the ear canal, thereby improving the playback effect in headband mode.

[0158] Reference Figure 15 and Figure 16 The earcup portion 210 is also configured to rotate rearward relative to the headband portion 100 about the forehead axis of the human body from its initial position, so that the earcup portion 210 is positioned in an outward position above the flat headband portion 100. The rotating connecting portion 330 rotates rearward relative to the headband portion 100 from its initial position about the forehead axis of the human body, thereby adjusting the angle of the earcup portion 210 relative to the headband portion 100, and thus adjusting the orientation of the outer side of the sound-emitting portion 220, thereby diversifying the sound output direction of the second speaker.

[0159] In some implementations, the earcup portion 210 is rotated a certain angle relative to the headband portion 100. When the headband portion 100 is placed flat on the support surface 400, the earcup portion 210 can be located above the headband portion 100, so that the sound-emitting portion 220 inside the earcup portion 210 can be suspended at a certain height relative to the headband portion 100, which helps to improve the sound transmission effect of the second speaker.

[0160] Figure 16 This is not a restriction on the placement of headphones in speaker mode. For example, headphones can also be used around the neck. Figure 5 As shown.

[0161] Reference Figure 14 The earcup portion 210 is configured to rotate forward by a first angle α from its initial position, where the first angle α is less than or equal to 20°. In its initial position, the first angle α is 0°. This can be understood as the rotating connection portion 330 being able to rotate forward relative to the headband portion 100 by an angle greater than 0° and less than or equal to 20°, meaning the forward rotation range of the earcup portion 210 is within 20°.

[0162] Combination Figure 15 The earcup portion 210 is configured to rotate rearward by a second angle β from its initial position, where the second angle β is less than or equal to 110°. In the initial position, the second angle β is 0°. This can be understood as the rotating connection portion 330 being able to rotate rearward relative to the headband portion 100 by an angle greater than 0° and less than or equal to 110°; that is, the rearward rotation range of the earcup portion 210 is within 110°. This allows the earcup portion 210 to have a large rearward adjustment angle range while avoiding an excessively large rearward rotation angle range and an excessively large clearance in the headband portion 100, thus ensuring the overall stability of the headband portion 100 when it is placed flat. When the headband portion 100 is placed flat, it acts as a base, supporting the earphone body 200 and ensuring that the earphone body 200 is suspended relative to the headband portion 100 without tipping over.

[0163] Reference Figure 18 In some embodiments of this application, mounting notches 101 are formed at both ends of the headband 100, and inner support arms 110 and outer support arms 120 are formed on both sides of the mounting notches 101, respectively. The inner support arms 110 and outer support arms 120 are arranged along the inward and outward directions of the headband 100 (corresponding to...). Figure 18 The inner support arm 110 is positioned relative to and spaced apart from the outer support arm 120, and is closer to the wearer's head than the outer support arm 120. The gap between the inner support arm 110 and the outer support arm 120 forms a mounting notch 101. The positive direction of the D2 axis is the outer side, and the negative direction of the D2 axis is the inner side.

[0164] At least one of the inner support arm 110 and the outer support arm 120 is provided with a second pivot 130, which is parallel to the frontal axis of the human body. For example, the outer support arm 120 is provided with the second pivot 130, and the second pivot 130 and the inner support arm 110 are spaced apart along the axial direction of the pivot, so that the rotatable connection part 330 can be fitted into the rotating hole 331 through the gap.

[0165] Reference Figure 17 and Figure 18The rotating connecting part 330 is inserted into the mounting notch 101 and is provided with a rotating hole 331; the rotating hole 331 is rotatably engaged with the second rotating shaft 130. The rotating shaft 130 is inserted into the rotating hole 311, so that the rotating connecting part 330 can rotate relative to the second rotating shaft 130. Other annular structures may also be provided between the rotating hole 331 and the second rotating shaft 130, so that the rotating hole 331 can rotate relative to the second rotating shaft 130.

[0166] With this configuration, the rotating connection 330 is embedded into the mounting notch 101, allowing the connection between the rotating connection 330 and the second pivot 130 to be hidden inside the mounting notch 101, which helps improve the appearance of the headphones. Furthermore, the second pivot 130 is located on the inner arm 110 and / or the outer arm 120. The inner arm 110 and the outer arm 120 can be made relatively thin, eliminating the need for thick areas to accommodate the pivot hole, resulting in a better overall appearance consistency for the headband 100.

[0167] In some embodiments, the rear side of the mounting notch 101 may also provide a limit for the rotating connection 330, that is, when the rotating connection 330 rotates rearward to contact the headband 100 on the rear side of the mounting notch 101, the rotating connection 330 rotates rearward to the maximum angle.

[0168] To ensure that the rotating connection 330 can be maintained at a certain angle relative to the headband 100, a damping structure is provided between the rotating connection 330 and the headband 100. The damping structure is located between the rotating hole 331 and the second rotating shaft 130 to generate rotational damping. The damping structure restricts the rotational position of the rotating connection 330 relative to the headband 100, thereby maintaining the earcup portion 210 at a certain angle.

[0169] In some possible implementations, the damping structure includes an elastic protrusion 332 and a mating recess 121. The elastic protrusion 332 is provided on one of the rotating connection 330 and the headband 100, while the other is provided with a plurality of mating recesses 121; the plurality of mating recesses 121 are arranged at intervals around the axis of rotation of the rotating connection 330 and the headband 100; the mating recesses 121 engage with the elastic protrusion 332.

[0170] Combination Figure 19 The second rotating shaft 130 is directly inserted into the rotating hole 331, so that the rotating connecting part 330 can rotate relative to the second rotating shaft 130. The rotating connecting part 330 is provided with an elastic protrusion 332, and the outer support arm 120 is provided with a plurality of mating recesses 121.

[0171] An open annular slit is provided on the rotating connection portion 330, and an elastic arm is formed within the open annular slit. The elastic arm can elastically deform relative to the rotating connection portion 330. One end of the elastic arm is connected to the rotating connection portion 330, and the other end of the elastic arm is provided with a protrusion. Thus, the elastic arm and the protrusion form an elastic protrusion 332.

[0172] The recess 121 can be a recess located on the inner side of the outer arm 120. The side of the outer arm 120 facing the inner arm 110 is the inner side of the outer arm 120.

[0173] When the rotating connection 330 rotates relative to the headband 100, the elastic protrusion 332 elastically deforms, causing the elastic protrusion 332 to rotate along with the rotating connection 330. When rotated to a certain angle, the protrusion of the elastic protrusion 332 engages with the mating recess 121, thereby keeping the earcup 210 stably at that angle, preventing the earcup 210 from rotating arbitrarily and affecting the stability of the wearing and the sound direction of the speaker 220 in external playback mode.

[0174] Reference Figure 17 and Figure 20 In some other possible implementations, the second pivot 130 includes a third shaft portion 131 and a fourth shaft portion 140, wherein the third shaft portion 131 is disposed on one of the inner support arm 110 and the outer support arm 120, and the fourth shaft portion 140 is disposed on the other of the inner support arm 110 and the outer support arm 120. For example, the third shaft portion 131 is disposed on the inner support arm 110, and the fourth shaft portion 140 is disposed on the outer support arm 120.

[0175] The fourth shaft portion 140 is provided with a shaft hole 141 so that the third shaft portion 131 can engage with the shaft hole 141.

[0176] The fourth shaft 140 is rotatably engaged with the rotating hole 331.

[0177] The damping structure includes a plurality of mating grooves 333 disposed on the wall of the rotating hole 331, and the plurality of mating grooves 333 are spaced apart circumferentially along the rotating hole 331; wherein the wall of the rotating hole 331 is wavy to form the plurality of mating grooves 333.

[0178] The damping structure also includes a spring 150 connected to the fourth shaft portion 140, the end of which engages with the mating groove 333.

[0179] For example, the fourth shaft portion 140 may include an inner ring 142 and an outer ring 143, with the inner ring 142 forming a shaft hole 141. The outer ring 143 is sleeved on the outside of the inner ring 142, and the outer ring 143 and the inner ring 142 are radially spaced to form an annular cavity 144. The outer ring 143 is provided with a through opening that communicates with the annular cavity 144.

[0180] The spring 150 includes an integrally formed annular portion 151, an intermediate connecting portion 152, and an elastic fitting portion 153. The annular portion 151 is inserted into the annular cavity 144. The intermediate connecting portion 152 connects the annular portion 151 and the elastic fitting portion 153 and protrudes from the through opening. The elastic fitting portion 153 is located outside the outer ring 143 and engages with the mating groove 333.

[0181] When the rotating connecting part 330 rotates relative to the headband part 100, the elastic fitting part 153 elastically deforms, allowing the rotating connecting part 330 to rotate relative to the fourth shaft part 140 and the spring piece 150, thereby causing the elastic fitting part 153 to rotate within multiple fitting grooves 333. When rotated to a certain angle, the elastic fitting part 153 engages with the fitting grooves 333, thereby keeping the earcup part 210 stably maintained at that angle and preventing the earcup part 210 from rotating arbitrarily relative to the headband part 100.

[0182] Of course, the damping structure between the rotating connection 330 and the headband 100 can also adopt other structures. For example, the second rotating shaft 130 can be a damping shaft, so that the rotating connection 330 and the headband 100 do not rotate arbitrarily, which helps to ensure the angle of the earcup 210 relative to the headband 100.

[0183] Reference Figure 4 In some embodiments of this application, an in-ear detection sensor 500 is provided on the inner side of the earphone body 200 facing the ear; when the in-ear detection sensor 500 detects that the earphone body 200 is worn on the ear, the external speaker function of the sound-emitting part 220 is configured to be disabled.

[0184] The in-ear detection sensor 500 can be located inside the sound-emitting part 220. For example, the in-ear detection sensor 500 can be installed at the front end inside the sound-emitting part 220, near the earcup part 210, which provides high detection accuracy.

[0185] The in-ear detection sensor 500 can be a proximity sensor, for example, a capacitive proximity sensor, which triggers a signal when the earphone body 200 is worn on the ear due to a change in capacitance. Alternatively, the in-ear detection sensor 500 can be an infrared photoelectric sensor, which amplifies the receiver signal and triggers a signal when the earphone body 200 is worn on the ear.

[0186] The in-ear detection sensor 500 can be a pressure sensor that triggers a signal by detecting the pressure of the sound-emitting part 220 when worn in the ear. This application embodiment does not limit the specific type of the in-ear detection sensor 500.

[0187] This application embodiment uses an in-ear detection sensor 500 to ensure that the external speaker mode will not be activated when the headphones are worn on the ears, regardless of how they are rotated, thus avoiding accidental activation of the external speaker mode and generating loud noise in the ears.

[0188] Regarding the over-ear headphones of this application embodiment, combined with Figure 2 The earcups 210 may be equipped with function keys 230, which can be used to switch between headband mode and speaker mode. Alternatively, the headband mode and speaker mode can also be switched via an app on a mobile device.

[0189] Therefore, through the above-described configuration, the headphones of this embodiment can switch between headphone mode and speaker mode by rotating the sound-emitting part 220 relative to the earcup part 210; the speaker mode can be activated by the interaction between the trigger 2441 and the position sensor 216; the speaker mode is disabled when the headphones are worn on the ears, as determined by the in-ear detection sensor 500; and the headphone mode and speaker mode can also be switched by using the function key 230 or other operations. The headphones of this embodiment offer diverse mode switching methods, facilitating flexible user operation.
