[0002] With the development of technology, more and more headphone devices are being used in daily life, providing convenience for people.

[0003] The headphone device can be, for example, a pair of over-ear headphones. Existing over-ear headphones generally include a headband and headphone bodies set at both ends of the headband. The headband is generally made of soft materials such as foam and silicone to make it comfortable to wear, while the headphone bodies are equipped with batteries, circuit boards and other electronic components. Therefore, the weight of the headphones is mainly distributed on the headphone bodies. When the user wears them, the stress point of the over-ear headphones is concentrated on the top of the user's head, which makes the user easily feel the weight of the headphones on the top of their head, reducing the user's comfort. At the same time, when the user wears over-ear headphones for a long time, the weight of the headphones will continue to press on the top of the user's head, resulting in poor user comfort.

Detailed Implementation

[0031] 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, and not all embodiments. Based on the embodiments described in 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.

[0032] It should be noted that all directional indicators (such as up, down, left, right, front, back, top, bottom) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0033] In this embodiment of the invention, the use of terms such as "first" and "second" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0034] In this embodiment, the headphone device 1 is, for example, a headphone, an in-ear headphone, an earbud headphone, and an on-ear headphone, etc. In this embodiment, the headphone device 1 is described using a headphone as an example.

[0035] See Figures 1-8 As shown, this utility model embodiment provides an earphone device 1, which includes, for example, a headband 10, a first earphone component 21, a second earphone component 22, a first support component 30, a second support component 40, and a circuit assembly 50.

[0036] Specifically, the headband 10 may be, for example, a portion of the headband of a conventional headset, and the headband 10 may be, for example, arc-shaped so as to fit snugly against the user's head. The headband 10, the first earphone 21, the second earphone 22, the first support member 30, and the second support member 40 together form a wearing space 70 for wearing.

[0037] The first earphone component 21 and the second earphone component 22 are respectively located at both ends of the headband component 10. The first earphone component 21 and the second earphone component 22 may be, for example, the main body of a pair of headphones, which includes, for example, an earpiece portion.

[0038] The first support member 30 is connected between the headband member 10 and the first earphone member 21. The second support member 40 is connected between the headband member 10 and the second earphone member 22. The first support member 30 and the second support member 40 are respectively disposed at both ends of the headband member 10. The first support member 30 and the second support member 40 may be, for example, a support structure with a receiving cavity, so that when the user wears the earphone device 1 on his head through the wearing space 70, the first support member 30 and the second support member 40 can fit against the user's head.

[0039] The circuit assembly 50 includes a first circuit section 51, a second circuit section 52, a third circuit section 53, and a fourth circuit section 54. The first circuit section 51 is disposed in the first earphone part 21, the second circuit section 52 is disposed in the second earphone part 22, the third circuit section 53 is disposed in the first support member 30, and the fourth circuit section 54 is disposed in the second support member 40. The circuit assembly 50 may be, for example, an assembly composed of electronic devices such as batteries, circuit boards, and electronic components. The first circuit section 51, the second circuit section 52, the third circuit section 53, and the fourth circuit section 54 may each include, for example, a circuit board. The four circuit boards are respectively disposed in the first earphone part 21, the second earphone part, the first support member 30, and the second support member 40, thereby reducing the weight of the circuit assembly placed within the first earphone part 21 and the second earphone part 22.

[0040] Because the weight of existing over-ear headphones is mainly distributed on the headphone body, namely the first and second earpieces, when a user wears the headphones, the force is concentrated on the top of the head, making the user feel the weight easily. Prolonged wear can also compress the top of the head, resulting in poor comfort. This embodiment of the invention divides the circuit assembly 50 into a first circuit section 51, a second circuit section 52, a third circuit section 53, and a fourth circuit section 54. The first circuit section 51 is located on the first earpiece 21, the second circuit section 52 on the second earpiece 22, the third circuit section 53 on the first support member 30, and the fourth circuit section 54 on the second support member 40. This effectively reduces the weight of the first earpiece 21 and the second earpiece 22 in the headphone device 1, distributing the weight of the headphone device 1 more evenly across the first support member 30, the second support member 40, the first earpiece 21, and the second earpiece 22. Therefore, when a user wears the headphone device 1, the excessive weight of the first earpiece 21 and the second earpiece 22 will not cause discomfort.

[0041] like Figures 1-2As shown, the first support member 30 and the second support member 40 are symmetrically arranged with respect to the headband member 10. This symmetrical arrangement can be, for example, axially symmetrical, where the axis of axial symmetry is the center position of the headband member 10, and the vertical direction of the center position serves as the axis of symmetry. The first support member 30 and the second support member 40 can be symmetrically arranged about this axis of symmetry. The symmetry of the first support member 30 and the second support member 40 can be understood as their positions being axially symmetrical about the center position of the headband member 10, and the specific structures of the first support member 30 and the second support member 40 can also be axially symmetrical about the center position of the headband member 10. By symmetrically arranging the first support member 30 and the second support member 40, the weight distribution of the headphone device 1 is more even, resulting in a more comfortable wearing experience for the user.

[0042] Specifically, such as Figure 2 , Figure 4 and Figure 5 As shown, the first circuit portion 51 includes a first circuit board 511. The first circuit board 511 is disposed in the first earphone component 21. The second circuit portion 52 includes a second circuit board 521, which is disposed within the first support member 30. The first circuit board 511 and the second circuit board 521 are electrically connected. The first circuit board 511 may, for example, house power supplies, rectified current devices, capacitors, etc., while the second circuit board 521 may, for example, house transformers, capacitors, and other electronic components. The third circuit portion 53 may, for example, include a third circuit board 531, which is disposed within the first support member 30. The fourth circuit portion 54 may, for example, include a fourth circuit board 541, which is disposed within the second support member 40. In this embodiment, the third circuit portion 53 further includes, for example, a first battery component 532, which may be, for example, a battery, and may be disposed within the first support member 30. The fourth circuit section 54 further includes, for example, a second battery component 542, which can be disposed within the second support member 40. The position of the second battery component 542 can be set according to actual conditions, and is not specifically limited here. By dividing the first circuit section 51 and the third circuit section 53 in the circuit assembly 50 into two parts, the weight is evenly distributed between the first earphone component 21 and the first support member 30. Similarly, by dividing the second circuit section 52 and the fourth circuit section 54 into two parts, the weight is evenly distributed between the second earphone component 22 and the second support member 40. This further distributes the weight of the earphone device 1, improving user wearing comfort.

[0043] Furthermore, such as Figures 4-5As shown, the first support member 30 includes a first housing 31, a second housing 32, and a first contact member 33. The first housing 31 and the second housing 32 are connected, and the connection between the first housing 31 and the second housing 32 forms a first receiving cavity 301. The second circuit board 521 is disposed within the first receiving cavity 301. The third circuit portion 53 is disposed within the first receiving cavity 301. In this embodiment, the first housing 31 may be, for example, the upper housing of the first support member 30; the second housing 32 may be, for example, the lower housing of the first support member 30; and the first contact member 33 may be, for example, the portion that contacts the user's head. Since the first support member 30 needs to contact the user's head, in order to further improve the user's wearing comfort, the first contact member 33 is wrapped around the second housing 32, so that the portion of the first support member 30 that contacts the user's head is the first contact member 33, and does not directly contact the second housing 32.

[0044] Furthermore, the first contact 33 is disposed on the surface of the second housing 32 away from the first housing 31, and when the user wears the headphone device 1, the first contact 33 contacts the user's head; and / or, the first contact 33 is a flexible structure. The flexible structure is, for example, composed of a soft material, such as foam, silicone, rubber, etc. Since the first support member 30 needs to contact the user's head, to further improve the user's wearing comfort, the first contact 33 is wrapped around the second housing 32, making the part of the first support member 30 that contacts the user's head soft, thereby improving the user's wearing comfort.

[0045] like Figures 6-7 As shown, the second support member 40 includes a third housing 41, a fourth housing 42, and a second contact member 43. The third housing 41 and the fourth housing 42 are connected and form a second accommodating cavity 401. The fourth circuit portion 54 is disposed within the second accommodating cavity 401. In this embodiment, the third housing 41 may be, for example, the upper housing of the second support member 40; the fourth housing 42 may be, for example, the lower housing of the second support member 40; and the second contact member 43 may be, for example, the portion that contacts the user's head.

[0046] Furthermore, the second contact 43 is disposed on the surface of the fourth housing 42 away from the third housing 41, and when the user wears the headphone device 1, the second contact 43 contacts the user's head; and / or, the second contact 43 is a flexible structure, which is composed of, for example, a soft material, such as foam, silicone, rubber, etc. The specific structure of the second support 40 is similar to that of the first support 30. The specific structure and effect of the second support 40 can be referred to the above description of the specific structure and effect of the first support 30, and will not be repeated here.

[0047] Furthermore, such as Figures 3-6 As shown, the headband 10 includes a first deformable portion 11 and a first flexible portion 14. The first flexible portion 14 is disposed on one side of the first deformable portion 11 and connected to it. The first deformable portion 11 is connected between the first support member 30 and the second support member 40. A first wiring groove (not shown) is provided on the first flexible portion 14. The third circuit portion 53 and the fourth circuit portion 54 are electrically connected through a first wire, which is disposed in the first wiring groove. The first deformable portion 11 may be composed of, for example, an elastic arm or a spring arm. By configuring the headband 10 to include the first deformable portion 11, the headphone device 1 can be easily deformed, thus making it more convenient for the user to wear the headphone device 1. Under the action of the spring arm, the first support member 30 and the second support member 40 are respectively clamped on both sides of the user's head, which also provides support and ensures that the pressure on the top of the head is even without pressure. The first flexible part 14 may be a component made of silicone, for example, which may surround the first deformable part 11 or be attached to the lower side of the first deformable part 11. A slot may be provided on the first flexible part 14, which is a wiring slot. The slot may be provided along the length direction of the first deformable part 11, for example. The first wire for the electrical connection between the third circuit part 53 and the fourth circuit part 54 may be placed in the slot.

[0048] like Figures 4-8 As shown, the first deformable part 11 is provided with a first sliding groove 111, and the first support member 30 and the second support member 40 are both slidably connected to the first deformable part 11 through the first sliding groove 111. The first sliding groove 111 can be, for example, a guide rail or a slide rail, so that the elastic arm can be slidably connected to the first support member 30 and the second support member 40 respectively by means of the guide rail or slide rail, thereby adjusting the size of the wearing space 70 of the headphone device 1.

[0049] Furthermore, such as Figures 4-8As shown, a first limiting structure 12 and a second limiting structure 13 are respectively provided at both ends of the first deformable portion 11. The first limiting structure 12 is located at the end of the first deformable portion 11 near the first support member 30. A third limiting structure 34 is provided inside the first support member 30. The first limiting structure 12 slides on the first groove 111 through the first deformable portion 11 to separate from or be limitedly connected to the third limiting structure 34. The second limiting structure 13 is located at the end of the first deformable portion 11 near the second support member 40. A fourth limiting structure 44 is provided inside the second support member 40. The second limiting structure 13 slides on the first groove 111 through the first deformable portion 11 to separate from or be limitedly connected to the fourth limiting structure 44. Specifically, one of the first limiting structure 12 and the third limiting structure 34 includes a limiting groove, and the other of the first limiting structure 12 and the third limiting structure 34 includes a protrusion. One of the second limiting structure 13 and the fourth limiting structure 44 includes a limiting groove, and the other of the second limiting structure 13 and the fourth limiting structure 44 includes a protrusion. Through the limiting structure cooperation between the protrusion and the limiting groove, it is possible to prevent the head beam 10 and the first support 30 from separating when they slide together, and also to prevent the head beam 10 and the second support 40 from separating when they slide together.

[0050] Furthermore, a first protrusion 15 is provided at one end of the first deformable part 11 near the first limiting structure 12, and a first slot 35 is provided inside the first support member 30. The first protrusion 15 and the first slot 35 are slidably connected. Multiple first slots 35 are arranged sequentially along the length of the first support member 30, and the first protrusion 15 engages with any one of the multiple first slots 35. The first protrusion 15 can be, for example, a raised spring, and the first slot 35 can be, for example, a slot. This groove structure corresponds to the raised spring. By providing multiple first slots 35, when the first deformable part 11 slides against the first support member 30, a fixed connection is achieved by engaging the first protrusion 15 with any one of the multiple first slots 35, thereby achieving fixation at different positions and meeting the needs of different users' head sizes.

[0051] The first deformable part 11 has a second protrusion 16 at one end near the second support member 40. The second support member 40 has a second slot 45. The second protrusion 16 and the second slot 45 are slidably connected. Multiple second slots 45 are arranged sequentially along the length of the second support member 40. The second protrusion 16 engages with any one of the multiple second slots 45. The second protrusion 16 is, for example, a raised spring, and the second slot 45 can be, for example, a slot or groove structure. By providing multiple second slots 45, when the first deformable part 11 slides against the second support member 40, a fixed connection is achieved by engaging the second protrusion 16 with any one of the multiple second slots 45, thus achieving fixation at different positions and meeting the needs of different users' head sizes.

[0052] Furthermore, such as Figures 1-3 As shown, the headphone device 1 further includes a first connector 25 and a second connector 26. The first connector 25 is connected between the first support member 30 and the first headphone member 21, and the second connector 26 is connected between the second support member 40 and the second headphone member 22. The first connector 25 and the second connector 26 may be, for example, elastic arms.

[0053] Furthermore, the first connector 25 includes a second deformable portion 251 and a second flexible portion 252. The second flexible portion 252 is disposed on one side of the second deformable portion 251 and connected to it. The second deformable portion 251 is connected between the first support member 30 and the first earphone member 21. A second wiring groove is formed on the second flexible portion 252. The first circuit portion 51 and the third circuit portion 53 are electrically connected by a second wire, which is disposed within the second wiring groove. The second deformable portion 251 is, for example, an elastic steel component. The second flexible portion 252 can be, for example, a long strip made of silicone. The second flexible portion 252 can wrap around the second deformable portion 251, or it can be disposed on the side of the second deformable portion 251 near the wearing space 70. The elastic steel component can be used to provide clamping force, and the second flexible portion 252 can have a wiring groove for wiring or placing wires for circuit board connections. Of course, in this embodiment, the first connector 25 and the first support 30 may also be provided with an anti-detachment structure composed of the first limiting structure 12 and the third limiting structure 34, and a locking structure composed of the first protrusion 15 and the first slot 35, which is similar to the connection structure of the first deformable part 11 and the first support 30; and / or, the second connector 26 includes a third deformable part 261 and a third flexible part 262, the third flexible part 262 is disposed on one side of the third deformable part 261 and connected to the third deformable part 261; the third deformable part 261 is connected between the second support 40 and the second earphone part 22, the third flexible part 262 is provided with a third wiring groove, the second circuit part (52) and the fourth circuit part 54 are electrically connected by a third wire, and the third wire is disposed in the third wiring groove. The third deformable part 261 is, for example, an elastic steel component, and the third flexible part 262 can be, for example, a long strip made of silicone. The third flexible part 262 can wrap around the third deformable part 261, or it can be positioned on the side of the third deformable part 261 closest to the wearing space 70. The elastic steel component can be used to provide clamping force, and the third flexible part 262 can have a cable routing groove for cable routing. The specific structure and effect of the second connector 26 can be specifically referred to the specific structure and effect of the first connector 25, and are not limited here.
