Description

Technical Field

[0001] This utility model relates to the field of headphone technology, specifically to a type of over-ear headphone. Background Technology

[0002] As a mainstream audio device, over-ear headphones have long suffered from the technical challenge of limited usage scenarios. For example, Chinese patent CN308146323S discloses an over-ear headphone. The common feature of these traditional over-ear headphones is that they completely cover the outline of the human ear, isolating external sounds and thus providing passive noise cancellation. This design leads to users being less sensitive to external loudspeaker and broadcast sounds. When wearing headphones while out and about, it's easy to overlook dangerous sounds, potentially causing accidents.

[0003] Chinese patent CN308879614S discloses a type of through-ear headphone. This headphone is an improvement on traditional over-ear headphones. It removes the earcups that cover the earpiece. Instead, it features a completely through-ear "O"-shaped ear loop within the earcup area, with the speaker unit suspended outside the ear, not directly pressing against it. This design allows external sound to pass through directly, solving the problem of blocking out hazard signals inherent in traditional over-ear headphones. However, when users need quiet time to enjoy music or audio programs, external noise can interfere with the listening experience, making it less focused than traditional over-ear headphones.

[0004] In summary, closed-back designs sacrifice safety, while through-hole designs sacrifice sound quality focus, and modular solutions fail to address the core functional transformation. Therefore, there is an urgent need for an earphone structure that can freely switch acoustic forms according to scenario requirements, ensuring environmental awareness while providing a physical noise isolation solution that can be activated on demand. Utility Model Content

[0005] In view of this, this utility model provides a pair of headphones to solve the problems of closed-back designs sacrificing safety, through-type designs sacrificing sound quality focus, and modular solutions failing to address the core functional switching issues. Therefore, there is an urgent need for a headphone structure that can freely switch acoustic forms according to scenario requirements, ensuring environmental awareness while providing a physical noise isolation solution that can be activated on demand.

[0006] In a first aspect, this utility model provides a headset, comprising:

[0007] A headband, with ear loops connected to both ends of the headband;

[0008] A sound-generating unit is mounted on the ear loop, and a sound-penetrating channel is provided between the sound-generating unit and the ear loop;

[0009] Ear cup housing, the ear cup housing being adapted to be mounted on the outside of the ear loop, the ear cup housing being used to open or close the sound penetration channel.

[0010] Beneficial effects: By incorporating an earcup shell that can open or close the sound channel, the earcup shell allows direct contact and communication between the external environment and the ear, ensuring natural ambient sound transmission and eliminating safety hazards. Conversely, when the earcup shell closes the sound channel, it cuts off the direct contact between the external environment and the ear, achieving passive noise cancellation and enhancing audio immersion. Users can freely switch headphone modes according to their environment, resolving the conflict between safety and noise cancellation requirements.

[0011] In one alternative embodiment, the earcup shell is detachably mounted on the ear loop. The earcup shell and the ear loop are connected by clips or magnets.

[0012] Beneficial effects: Using clips, slots, or magnets for connection, the earcups can be completely detached or installed onto the ear loops, allowing for instant switching between through-ear and closed-back configurations to meet various needs. The clips and magnets ensure a full circumferential fit between the earcups and ear loops, guaranteeing a tight, seamless seal and preventing sound leakage in closed-back mode, thus improving passive noise cancellation. The clips or magnets do not alter the basic structure of the ear loops and earcups, are compatible with different materials, and support diverse accessory expansions. Users can complete installation and removal without tools, enhancing the user experience.

[0013] In one alternative embodiment, the device further includes a pivot and a spindle, the pivot being mounted on the ear loop and the spindle being mounted on the earcup housing corresponding to the pivot, the spindle being rotatably connected to the pivot to allow the earcup housing to rotate relative to the ear loop.

[0014] Beneficial effects: The earcups allow for flexible rotation relative to the ear loops. Rotating upwards opens the sound channel, satisfying the user's need to perceive external sounds, making it suitable for commuting and outdoor activities. Rotating downwards allows the earcups to fit snugly against the ear loops, sealing the sound channel and reducing external noise, ideal for quiet listening environments. The hinge structure can be installed in different positions on the earcups and ear loops, allowing the earcups to rotate in different directions. This ensures the ability to open or close the sound channel while enhancing the design's flexibility and adaptability.

[0015] In an alternative embodiment, a connecting fork is also included, which is mounted at the end of the headband;

[0016] The connecting fork has a rotating shaft at both ends, and the ear loop has a mounting hole corresponding to the rotating shaft. The rotating shaft is inserted into the mounting hole to install the ear loop on the connecting fork.

[0017] In one alternative embodiment, the inner diameter of the mounting hole is equal to the outer diameter of the rotating shaft.

[0018] Beneficial effects: The semi-circular arc shape of the connecting fork, combined with the connection structure between the rotating shaft and the mounting hole, enables the ear loop to rotate relative to the connecting fork, improving the angular adaptability of the headphones during wear. This allows for a better fit to the ear contours of different users, enhancing wearing comfort. The design where the inner diameter of the mounting hole is equal to the outer diameter of the rotating shaft ensures the stability of the ear loop during rotation, preventing wobbling or shifting and ensuring the structural stability of the headphones during use.

[0019] In one alternative embodiment, the earcup shell and the ear loop are connected by a snap, magnet, thread, or interference friction.

[0020] In one alternative embodiment, the earcup shell is made of one or more combinations of plastic, resin, rubber, metal, woven fabric, and plush.

[0021] Beneficial effects: The design features earcups made of various materials, allowing users to switch between different earcups for a unique sound experience.

[0022] In one alternative embodiment, a sensor switch is also installed on the ear loop or the sound-generating unit, the sensor switch being used to determine whether the earcup shell is attached to or detached from the outer surface of the ear loop.

[0023] In one alternative implementation, the headphones further include an active noise cancellation module installed within the sound-generating unit.

[0024] In one alternative embodiment, the headphones further include a light-emitting module, which is installed within one or more of the sound-emitting unit, the earcups, or the headband. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] As a mainstream audio device, over-ear headphones have long suffered from the technical dilemma of limited usage scenarios. Closed-back designs sacrifice safety, while through-hole designs sacrifice focused sound quality, and modular solutions fail to address the core functional transformation. Therefore, there is an urgent need for a headphone structure that can freely switch acoustic forms according to scenario requirements, ensuring environmental awareness while providing a physical noise isolation solution that can be activated on demand.

[0039] To solve the above technical problems, the following will be combined with... Figures 1 to 3 The following describes embodiments of the present invention.

[0040] According to an embodiment of the present invention, one aspect provides a headset, including: a headband 1, ear loops 2, a sound-generating unit 3, and an earcup shell 5.

[0041] like Figures 1 to 3As shown, the headband 1 is an arc-shaped wire beam, and ear loops 2 are installed on both sides of the headband 1. The ear loops 2 are circular or arc-shaped and have through holes inside. The sound-generating unit 3 is fixed to the inner wall of the ear loop 2 by a connecting block. The sound-generating unit 3 partially blocks the through holes, leaving a sound-penetrating channel 4 between the inner wall of the ear loop 2 and the sound-generating unit 3. The earcup shell 5 is adapted to be installed on the outside of the ear loop 2. The earcup shell 5 is used to open or close the sound-penetrating channel 4.

[0042] The aforementioned structure incorporates an earcup shell 5, which can open or close the sound-penetrating channel 4. When the earcup shell 5 opens the sound-penetrating channel 4, the external environment is directly connected to the ear, ensuring natural ambient sound transmission and eliminating safety hazards. Conversely, when the earcup shell 5 closes the sound-penetrating channel 4, it cuts off the direct contact between the external environment and the ear, achieving passive noise cancellation and enhancing audio immersion. Users can freely switch headphone modes according to their environment, resolving the conflict between balancing safety and noise cancellation requirements.

[0043] Specifically, such as Figure 1 As shown, the shape of the earcup shell 5 is adapted to the shape of the ear loop 2, and the earcup shell 5 can be detachably installed on the ear loop 2. For example, a structure such as a buckle or magnet can be installed between the outer surface of the earcup shell 5 and the outer surface of the ear loop 2. A buckle is installed on the earcup shell 5, and a groove is opened on the outer surface of the ear loop 2. The buckle is engaged in the groove to install the earcup shell 5 on the ear loop 2, ensuring that the earcup shell 5 and the outer surface of the ear loop 2 are in close contact. Alternatively, a ring of magnets is placed on the earcup shell 5, and a ring of magnets is also placed on the outer surface of the ear loop 2. The opposing faces of the two rings of magnets have opposite magnetic properties, and the earcup shell 5 is tightly attached to the outer surface of the ear loop 2 by magnetism.

[0044] With the above-described configuration, the earcup shell 5 can be completely detached or installed onto the ear loop 2 via a snap-fit ​​or magnet connection, enabling a near-instantaneous switch between through-type and closed-back configurations to meet various scenario requirements. The snap-fit ​​or magnet ensures a full-circumference fit between the earcup shell 5 and the ear loop 2, guaranteeing a tight, seamless fit that prevents sound leakage in closed-back mode and enhances passive noise cancellation. The snap-fit ​​or magnet interface does not alter the basic structure of the ear loop 2 and earcup shell 5, is compatible with different materials, and supports diverse accessory expansion. Users can complete installation and removal without tools, improving the smoothness of the experience.

[0045] In addition, in other possible implementations, the earcup housing 5 and the ear loop 2 can also be connected by threads or by interference friction during insertion and removal.

[0046] In other embodiments, the headband 1 can be a single unit, a fixed-length component, an adjustable-length headband 1, or a segmented foldable headband 1. The two ends of the headband 1 can be fixedly connected to the ear loops 2 or detachably connected. There can be a certain degree of freedom of movement between the headband 1 and the ear loops 2. For example, the ear loops 2 can be connected to the headband 1 via a swivel ball joint, ensuring that the ear loops 2 can deflect relative to the headband 1. This allows them to fit the ear more closely and improve comfort. The ear loops 2 and the sound-emitting unit 3 can be a single unit or detachably connected to the ear loops 2. There can be a certain degree of freedom of movement between the sound-emitting unit 3 and the ear loops 2. For example, the ear loops 2 can be connected to the sound-emitting unit 3 via a swivel ball joint, ensuring that the sound-emitting unit 3 can deflect relative to the ear loops 2, changing the sound-emitting angle of the sound-emitting unit 3.

[0047] In one embodiment, such as Figure 2 As shown, a hinge structure can also be directly installed on the earcup shell 5 and the ear loop 2. The hinge structure includes a pivot 61 and a spindle 62. The pivot 61 is mounted on the upper outer surface of the ear loop 2, and the spindle 62 is mounted on the upper inner wall of the earcup shell 5, corresponding to the pivot 61. The spindle 62 is mounted on the pivot 61 and can rotate on the pivot 61, allowing the earcup shell 5 to flip upwards relative to the ear loop 2 to open the sound channel 4, or to flip downwards so that the earcup shell 5 fits against the ear loop 2 to close the sound channel 4. Similarly, the hinge structure can not only be installed on the upper ends of the earcup shell 5 and the ear loop 2, but also in other positions, allowing the earcup shell 5 to flip in different directions, as long as it satisfies the requirement that the earcup shell 5 fits against the ear loop 2 to close the sound channel 4 or flips to open the sound channel 4.

[0048] The aforementioned structure allows for flexible rotation of the earcup shell 5 relative to the ear loop 2. Rotating upwards opens the sound channel 4, satisfying the user's need to perceive external sounds, making it suitable for commuting and outdoor activities. Rotating downwards allows the earcup shell 5 to fit snugly against the ear loop 2, sealing the sound channel 4 and reducing external noise, making it suitable for quiet listening environments. The hinge structure can be installed in different positions on the earcup shell 5 and ear loop 2, allowing the earcup shell 5 to rotate in different directions. While ensuring the ability to open or close the sound channel 4, this enhances the design's flexibility and adaptability.

[0049] In one embodiment, such as Figure 3 As shown, the headphones also include a connecting fork 7, the fork of which is semi-circular in shape, and the top of the connecting fork 7 is mounted on the end of the headband 1; rotating shafts 71 are fixed at both ends of the connecting fork 7, and the ear loops 2 are provided with mounting holes 21 corresponding to the rotating shafts 71. The rotating shafts 71 are inserted into the mounting holes 21 to mount the ear loops 2 on the connecting fork 7, so that the ear loops 2 can rotate relative to the connecting fork 7. The inner diameter of the mounting hole 21 is equal to the outer diameter of the rotating shaft 71.

[0050] The fork of the connecting fork 7 is semi-circular, and in conjunction with the connection structure between the rotating shaft 71 and the mounting hole 21, it enables the ear loop 2 to rotate relative to the connecting fork 7. This improves the angular adaptability of the headphones when worn, allowing them to better fit the ear contours of different users and enhance wearing comfort. The design that the inner diameter of the mounting hole 21 is equal to the outer diameter of the rotating shaft 71 ensures the stability of the ear loop 2 during rotation, preventing wobbling or displacement during rotation and ensuring the structural stability of the headphones during use.

[0051] In other embodiments, the two ends of the headband 1 can be fixedly connected to the connecting fork 7 or detachably connected. There can be a certain degree of freedom of movement between the headband 1 and the connecting fork 7. For example, the connecting fork 7 can be connected to the headband 1 via a steering ball joint, ensuring that the connecting fork 7 can deflect relative to the headband 1. This allows the ear loops 2 to fit more snugly to the ear, improving comfort.

[0052] In one embodiment, the earcup shell 5 is made of one or more combinations of plastic, resin, rubber, metal, woven fabric, and plush. Designing earcup shells 5 with various materials allows users to switch between different shells for a unique sound experience. The earcup shell 5 can be made in different colors, patterns, materials, and finishes, and can be worn as a fashionable accessory.

[0053] In one embodiment, an inductive switch is also installed on the ear loop 2 or the sound-generating unit 3. The inductive switch is used to determine whether the earcup shell 5 is in contact with or detached from the ear loop 2. The inductive switch includes, but is not limited to, mechanical push switches, electronic contact switches, circuit connection switches, magnetic inductive switches, etc.

[0054] In one embodiment, the headphones also include an active noise cancellation module, which is installed inside the sound-generating unit 3. When the earcup shell 5 detaches from the ear loop 2 and opens the sound channel 4, a sensor switch causes the active noise cancellation module to automatically stop working. When the earcup shell 5 is attached to the ear loop 2, the sound channel 4 is closed, and the sensor switch causes the active noise cancellation module to automatically activate active noise cancellation.

[0055] In one embodiment, the headphones also include a light-emitting module, which is installed within one or more of the sound-generating unit 3, earcups 2, and headband 1. The light-emitting module, linked to a sensor switch, indicates the status through its color; for example, a red light indicates a desire for quiet when the earcup shell 5 is attached, while a green light indicates a willingness to engage in conversation when the earcup shell 5 is removed.

[0056] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
