Description

Technical Field

[0001] This application relates to the field of headphone technology, and more particularly to a type of over-ear headphone. Background Technology

[0002] In related technologies, to ensure that headphones have a relatively long battery life, a battery is usually placed inside the headphone unit. However, if the battery and other electronic components inside the headphone unit are not arranged properly, the headphone unit of the headphones will be too thick. Therefore, it is particularly important to reduce the thickness of the headphone unit while ensuring the acoustic performance of the headphones. Utility Model Content

[0003] This application provides a type of over-ear headphone designed to reduce the thickness of the headphone unit.

[0004] To address the aforementioned technical problems, this application provides a headset, comprising a headband and earphone units connected to both ends of the headband; each earphone unit includes an ear shell, a speaker assembly, and a battery; the ear shell is connected to the headband, and an internal cavity is provided within the ear shell; the speaker assembly is disposed within the cavity, dividing the cavity into a front chamber and a rear chamber; the speaker assembly has a receiving groove on its side facing the rear chamber; the battery is electrically connected to the speaker assembly, and at least partially located within the receiving groove, with the battery and speaker assembly nested together in the thickness direction of the ear shell.

[0005] To address the aforementioned technical problems, this application also provides a headset, which includes a headband and earphone units connected to both ends of the headband. The earphone units include ear shells, speaker components, and batteries. The ear shell is connected to the headband, and the ear shell has an internal cavity; the speaker assembly is disposed in the cavity, and the speaker assembly divides the cavity into a front chamber and a rear chamber; the battery is electrically connected to the speaker assembly, and the battery is arranged in a ring and sleeved on the outside of the speaker assembly; in the thickness direction of the ear shell, the battery and the speaker assembly are nested together.

[0006] The beneficial effects of this application are as follows: Since the headphone unit contains a battery that powers the headphones, i.e., the battery powers the speaker assembly, and the internal space of the headphone unit is limited, and the battery itself has a certain volume, it will undoubtedly occupy the internal space of the headphone unit. Therefore, this application sets up a receiving slot in the speaker assembly, and the battery is at least partially located in the receiving slot. Compared with the previous stacked design, this arrangement can significantly improve the space reuse rate of the headphone unit along the thickness direction. In other words, the battery and the speaker assembly share the thickness space in the thickness direction of the headphone unit, thereby reducing the overall thickness of the headphone unit, making the headphone unit lighter and thinner, and also helping to improve the structural compactness between the battery and the speaker assembly, thereby improving the structural compactness of the single unit of the headphones.

[0010] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0011] This application provides a pair of headphones 100. Please refer to [reference needed]. Figure 1 The headset 100 includes a headband 1001 and two earphone units 1002, which are respectively connected to both ends of the headband 1001. Exemplarily, the connection between the earphone units 1002 and the headband 1001 can be a fixed connection or a rotatable connection. During wear, the headband 1001 spans the user's head and provides a certain elastic clamping force to cover one earphone unit 1002 over the user's ear. For ease of description, the side of the earphone unit 1002 facing the user's ear is defined as the front side or front, while the side facing away from the ear is defined as the back side or back.

[0012] The headband 1001 has a curved, arc-shaped structure to adapt to the user's head contour. The headband 1001 can be telescopically adjustable and includes a frame and a cover that covers the frame. The frame can be made of plastic or metal, while the cover can be made of soft materials such as leather or fabric, providing a more comfortable feel when in contact with the user. The frame can have multiple connecting units, and two connecting units can be connected by a sliding mechanism. This allows for length adjustment of the headband 1001 by sliding and pulling between two connecting units to accommodate users with different head sizes, improving user convenience and comfort.

[0013] Please refer to Figures 1 to 5 The headphone unit 1002 includes an ear shell 10, a speaker assembly 20, and a battery 30.

[0014] The earpiece 10 is connected to the headband 1001. For example, one end of the headband 1001 along its length is fixedly connected to the outer periphery of the earpiece 10, or one end of the headband 1001 along its length is swivelly or slidably connected to the earpiece 10. The earpiece 10 can be circular, square, or other shapes. An open-ended cavity is formed within the earpiece 10 to provide a mounting base for components such as the speaker assembly 20 and the battery 30. The earpiece 10 can be made of metal (such as aluminum). Metal materials can improve the overall rigidity of the earpiece 10, enhance its impact resistance, and provide better protection for the internal components. It is understood that the earpiece 10 can also be made of other materials (such as plastic). Plastic is easy to mold and inexpensive.

[0015] The speaker assembly 20 is disposed within the ear shell 10 and can cover the opening of the receiving cavity. The speaker assembly 20 divides the receiving cavity into a front chamber and a rear chamber 101. The rear chamber 101 is formed by the speaker assembly 20 and the ear shell 10. The speaker assembly 20 has a receiving groove 201 on one side facing the rear chamber 101. The battery 30 is disposed within the ear shell 10, that is, within the rear chamber 101. The battery 30 is electrically connected to the speaker assembly 20. The battery 30 and the speaker assembly 20 are nested together in the thickness direction of the ear shell 10. The battery 30 is at least partially located within the receiving groove 201; that is, the entire battery 30 can be completely located within the receiving groove 201, or only a portion of the battery 30 along its thickness direction can be located within the receiving groove 201. It should be noted that the battery 30 can be fixed to the ear shell 10 or the speaker assembly 20 by at least one of the following methods: adhesive, snap-fit, or screw-fit, to ensure that the battery 30 is stably disposed within the ear shell 10.

[0016] Since the battery 30 has a certain volume, it will undoubtedly occupy the internal space of the headphone unit 1002. Based on the above solution, a receiving groove 201 is provided through the speaker assembly 20, and the battery 30 is at least partially located in the receiving groove 201. Compared with the previous stacked design, this arrangement can significantly improve the space reuse rate of the headphone unit 1002 along the thickness direction. That is to say, the battery 30 and the speaker assembly 20 share the thickness space in the thickness direction of the headphone unit 1002, thereby reducing the overall thickness of the headphone unit 1002, making the headphone unit 1002 thinner and lighter. It also helps to improve the structural compactness between the battery 30 and the speaker assembly 20, thereby improving the structural compactness of the single unit of the headphone 100.

[0017] Furthermore, in some embodiments of this application, the battery 30 is flat, and the thickness direction of the battery 30 is consistent with the thickness direction of the earpiece 10. With the battery 30 at least partially located in the receiving groove 201, the flat arrangement of the battery 30 reduces the space occupied by the battery 30 in the thickness direction, thus enabling a thinner design for the single unit. It is understood that the flat arrangement of the battery 30 allows for a relatively large surface area, and the thinner battery 30, when subjected to external pressure (such as when the headphones 100 fall or are compressed during storage), the pressure is evenly distributed across the entire surface of the battery 30, rather than concentrated at a single point. This meets the drop and pressure resistance requirements suitable for portable applications.

[0018] In some embodiments of this application, the receiving slot 201 is located in the middle of the speaker assembly 20. This arrangement can, on the one hand, reasonably divide the internal space of the headphone unit, helping to free up space for the battery 30 to be nested, thus achieving a thinner and lighter design for the headphone unit 1002; on the other hand, when the battery 30 is embedded in the receiving slot 201, the battery 30 can be located approximately in the middle of the headphone unit 1002, which can reasonably distribute the weight of the headphone unit 1002 and help improve the wearing comfort of the headphones 100; furthermore, the battery 30 can be surrounded and protected by the speaker assembly 20 from all sides. This embedded form allows the battery 30 and the speaker assembly 20 to support each other, forming a very compact and highly rigid integral module with stronger resistance to compression and impact.

[0019] Please refer to Figures 2 to 5 In some embodiments of this application, the speaker assembly 20 divides the space within the ear shell 10 into a rear chamber 101 located behind the speaker assembly 20. A receiving groove 201 connects to the rear chamber 101. A portion of the battery 30 is located in the receiving groove 201, and another portion is located in the rear chamber 101. This arrangement allows the battery 30 to reuse the receiving groove 201 of the speaker assembly 20 in the thickness direction within the rear chamber 101. This makes the structure between the ear shell 10, speaker assembly 20, and battery 30 more compact, avoids wasting space, improves the space utilization of the headphone unit 1002, and achieves a reduction in the thickness of the headphone unit 1002, thereby making the headphone unit 1002 thinner and lighter.

[0020] Understandably, the portion of the battery 30 located in the rear chamber 101 is fixedly connected to the ear shell 10. For example, the battery 30 can be glued and fixed to the ear shell 10 to ensure that the battery 30 is stably installed inside the ear shell 10, while effectively preventing the battery 30 from shifting position, avoiding affecting the normal operation of the speaker assembly 20, and ensuring the acoustic performance of the headphone unit 1002.

[0021] Please refer to Figure 6 and Figure 7Furthermore, in some embodiments of this application, the speaker assembly 20 includes a speaker bracket 202 and a speaker unit 203 disposed on the speaker bracket 202. The speaker bracket 202 is connected to the ear shell 10. Specifically, the speaker bracket 202 covers the opening of the receiving cavity of the ear shell 10 and, together with the speaker unit 203, forms a rear chamber 101 with the ear shell 10. The speaker unit 203 has a receiving groove 201 on the side facing the rear chamber 101. In this embodiment, the receiving groove 201 can be a circular space or a rectangular space to accommodate a circular battery 30 or a rectangular battery 30, thereby improving the performance of accommodating batteries 30 of different sizes.

[0022] Within the limited internal space of the headphone unit 1002, and with the speaker unit 203 already occupying the core area, the speaker unit 203 defines the receiving slot 201. This allows the battery 30 to be embedded within the receiving slot 201, reducing the space occupied by the battery 30 in the rear chamber 101. This frees up space in other areas of the rear chamber 101 for components such as the flexible circuit board 40, avoiding problems like messy wiring and poor heat dissipation caused by space constraints. Simultaneously, there's no need to design a thicker ear shell 10 or additional support to accommodate the battery 30, reducing the weight of redundant structures and improving wearing comfort, such as reducing head pressure during prolonged use of the headphones 100. Furthermore, embedding the battery 30 within the receiving slot 201 inside the speaker unit 203 results in a compact structure, allowing for more design leeway, such as adding an active noise cancellation module without significantly increasing the size of the headphone unit 1002.

[0023] It is understandable that the speaker unit 203 will vibrate when it is working. After fixing the battery 30 to the ear shell 10, the battery 30 is placed in the receiving groove 201. Since the magnetic circuit system of the speaker unit 203 has a certain rigidity, the magnetic circuit system of the speaker unit 203 forms a wrapping fixation for the battery 30, which can greatly reduce the risk of displacement of the battery 30 and improve the power supply stability.

[0024] Please refer to Figures 8 to 10 In some embodiments of this application, the speaker unit 203 includes a vibration system and a magnetic circuit system. The inner side of the speaker bracket 202 is recessed to the outer side to form a mounting groove 2021 that communicates with the rear chamber 101. The speaker unit 203 is disposed in the mounting groove 2021. The speaker bracket 202 is also provided with a flange 2022 that is arranged in a ring and surrounds the opening of the mounting groove 2021. The outer peripheral side of the speaker unit 203 is fixed to the inner side of the flange 2022 to achieve fixed installation.

[0025] The vibration system includes a diaphragm 2031 and a voice coil 2032 connected to the diaphragm 2031. The magnetic circuit system includes a center magnet 2033 and a side magnet 2034. The center magnet 2033 is T-shaped and includes a base 2033a and an edge portion 2033b connected to the base 2033a. The side magnet 2034 is disposed on the edge portion 2033b and surrounds the base 2033a. A voice coil is formed between the side magnet 2034 and the base 2033a. The magnetic gap 2035 inserted in 2032 has a recessed receiving groove 201 formed on the surface of the base 2033a facing the rear chamber 101. The receiving groove 201 can be formed by the base 2033a recessed in the direction of the back of the ear shell 10 towards the diaphragm 2031. The receiving groove 201 can penetrate the base 2033a along the thickness direction of the ear shell 10, or it can not penetrate the base 2033a. In this embodiment, the receiving groove 201 does not penetrate the base 2033a.

[0026] It is understood that the outer periphery of the side magnet 2034 is fixedly connected to the inner side of the flange 2022, such as by at least one of the following methods: bonding, snap-fitting or screwing; or, the side magnet 2034 is fixed to the inner side of the flange 2022 by an auxiliary bracket, and the periphery of the diaphragm 2031 is fixedly connected to the auxiliary bracket.

[0027] It should be noted that the speaker unit 203 occupies the core area of ​​the internal space of the ear shell 10. In this embodiment, a receiving groove 201 is formed by the indentation on the inner side of the base 2033a, and the battery 30 is at least partially located in the receiving groove 201. In this way, the battery 30 can reuse the inner space of the central magnet 2033 in the thickness direction, thereby reducing the overall thickness of the headphone unit 1002. In addition, the battery 30 can also act as an acoustic damper. The battery 30 itself has a fixed volume and occupies part of the volume of the rear chamber 101. When the diaphragm 2031 vibrates, the air in the rear chamber 101 flows slowly from the gap between the battery 30 and the side wall of the receiving groove 201 or from the tiny gaps on the surface of the battery 30, thereby achieving a damping effect that hinders the rapid flow of air. There is no need to add an additional damping structure (such as damping cotton), avoiding increasing the size of the headphone unit 1002, which is more conducive to reducing the overall thickness of the headphone unit 1002.

[0028] Understandably, when the diaphragm 2031 vibrates, it transmits sound not only through the air but also through structures such as the speaker bracket 202 and ear shell 10, transmitting structural sound (such as noise and resonance). Since the battery 30 itself has a certain weight and rigidity, it can act as a vibration damping structure within the receiving slot 201 and the rear chamber 101, absorbing some of the vibration energy generated by the diaphragm 2031 and reducing the transmission of vibration to the ear shell 10 or other components. This reduces the interference of structural sound on sound quality and improves the purity of the sound.

[0029] Please continue to refer to Figures 8 to 10 Furthermore, in some embodiments of this application, the central magnet 2033 includes a rear surface 2033c. Along the thickness direction of the earphone, the receiving groove 201 is annular, that is, the receiving groove 201 is an annular groove. The annular groove is formed by the recess of the rear surface 2033c toward the diaphragm 2031, and the annular groove does not penetrate the base 2033a along the thickness direction of the ear shell 10. The battery 30 can be arranged in annular shape, that is, an annular battery 30. Along the thickness direction of the ear shell 10, a part of the annular battery 30 is located in the receiving groove 201, and another part is located in the rear cavity 101.

[0030] Alternatively, the receiving groove 201 can be an annular groove, formed by a recess in the rear surface 2033c towards the diaphragm 2031. The annular groove does not penetrate the base 2033a along the thickness direction of the ear shell 10. The battery 30 is arranged in a block shape, and the number of batteries 30 includes at least two, arranged in series. These at least two batteries 30 are distributed circumferentially along the annular groove, that is, distributed circumferentially along the central magnet 2033 within the receiving groove 201. Compared to a single-piece battery 30, the arrangement of multiple batteries 30 connected in series is more flexible. Furthermore, by providing stable high-voltage DC power through multiple series-connected batteries 30, the magnetic field strength of the magnetic gap 2035 can be enhanced, which helps to increase the driving force of the voice coil 2032. This, in turn, can optimize the vibration of the diaphragm 2031 (e.g., response speed, dynamics, linearity), thereby reducing sound distortion, improving detail and low-frequency performance, and ultimately improving sound quality.

[0031] Please refer to Figures 2 to 5 Furthermore, in some embodiments of this application, the speaker unit 203 includes a vibration system and a magnetic circuit system. The vibration system includes a diaphragm 2031 and a voice coil 2032 connected to the diaphragm 2031. The magnetic circuit system includes a center magnet 2033 and a side magnet 2034. The center magnet 2033 is T-shaped and includes a base 2033a and an edge portion 2033b connected to the base 2033a. The side magnet 2034 is disposed on the edge portion 2033b and surrounds the base 2033a. A magnetic gap 2035 is formed between the side magnet 2034 and the base 2033a for the voice coil 2032 to be inserted. A receiving groove 201 is formed in the base 2033a, and the receiving groove 201 penetrates the base 2033a and leads to the diaphragm 2031. That is, the receiving groove 201 penetrates the base 2033a along the thickness direction of the ear shell 10. With the battery 30 located in the receiving slot 201, that is, on the basis of reusing the space of the battery 30 and the acoustic space, the battery 30 avoids occupying the volume of other areas of the rear chamber 101, thereby helping to make the headphone unit 1002 smaller and thinner, and realizing the lightweight design of the over-ear headphones 100.

[0032] Understandably, the receiving slot 201 forms part of the rear chamber 101. The rear chamber 101 of the headphone unit 1002 is one of the core acoustic structures that determines low-frequency response and distortion. The volume, sealing, and internal damping of the rear chamber 101 directly affect the sound quality. The battery 30 itself has a fixed volume, and part of the battery 30 is located in the receiving slot 201. This means that the physical volume of the battery 30 fills and defines the effective space of the rear chamber 101. Compared with the traditional method of filling the rear chamber 101 with sponge, the rigid volume of the battery 30 is more stable, which can keep the volume of the rear chamber 101 precise and consistent, avoiding sound quality deviations caused by differences in sponge compression during production, thus making the low-frequency response more stable and consistent.

[0033] Since part of the battery 30 is located in the receiving groove 201 and the other part is located in the rear chamber 101, and the outer shell of the battery 30 is usually made of metal or hard plastic, the outer surface of the battery 30 and the inner wall of the receiving groove 201 and the back of the diaphragm 2031 will form tiny gap channels. When the diaphragm 2031 vibrates, the air needs to flow through these gaps. This process will generate air damping, which is equivalent to adding a moderate resistance to the vibration of the diaphragm 2031. In this way, the excessive vibration of the diaphragm 2031 can be effectively suppressed (avoiding excessively high low-frequency peaks), thereby optimizing the low-frequency Q value to a more ideal range (usually close to 0.7, balancing depth and clarity), reducing low-frequency distortion, and making the low frequencies cleaner and more elastic.

[0034] Furthermore, in some embodiments of this application, the gap between the battery 30 and the diaphragm 2031 is set to be no less than 1.2 mm. Since the battery 30 is partially located within the receiving slot 201, it is equivalent to the battery 30 being partially embedded within the speaker unit 203. If the gap between the battery 30 and the diaphragm 2031 is too small, the back of the diaphragm 2031 may directly rub against the battery 30, resulting in a hissing friction noise, or rubbing noise. In severe cases, this can cause the diaphragm 2031 to deform, become stuck, and completely lose its sound-producing ability. If the gap between the battery 30 and the diaphragm 2031 is too large, it will undoubtedly increase the thickness of the headphone unit 1002. To ensure that there is sufficient gap to prevent the vibration of the diaphragm 2031 from being physically interfered with and to prevent deformation during long-term use, and to ensure stable air damping effect (optimizing the low-frequency Q value) through precise gap size, while also taking into account the feasibility of production and assembly, the gap between the battery 30 and the diaphragm 2031 can be set to 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, etc.

[0035] In some embodiments, the bottom of the mounting groove 2021 is recessed from the inside to the outside of the speaker bracket 202, so as to form an avoidance protrusion 2024 on the outside of the speaker bracket 202 and at the location corresponding to the mounting groove 2021. The avoidance protrusion 2024 is used to provide space for the vibration of the diaphragm 2031 and avoid the phenomenon of ring rubbing.

[0036] Please refer to Figure 11 and Figure 12 In some embodiments of this application, based on the premise that the accommodating cavity is divided into a front chamber and a rear chamber 101 by the speaker assembly 20, the battery 30 may not be disposed inside the speaker assembly 20, but may be disposed outside the speaker assembly 20. Therefore, in this embodiment, the battery 30 may be arranged in a ring shape and sleeved outside the speaker assembly 20. That is to say, the ring-shaped battery 30 may be located outside the entire speaker assembly 20, so that the battery 30 and the speaker assembly 20 are nested in the thickness direction of the ear shell 10.

[0037] The speaker assembly 20 includes a speaker bracket 202 and a speaker unit 203 disposed on the speaker bracket 202. The speaker bracket 202 is connected to the ear shell 10. It is understood that the annular battery 30 can be arranged around the speaker unit 203. The annular battery 30 can be positioned around the speaker unit 203 by either fitting the annular battery 30 onto the outer periphery of the speaker unit 203, or by the speaker bracket 202 forming an annular space around the speaker unit 203 to accommodate the annular battery 30. In this embodiment, the speaker bracket 202 forming a certain accommodating space for the annular battery 30 is used as an example. The speaker bracket 202 has an accommodating groove 201 surrounding the speaker unit 203. That is, the battery 30 is located on the outer periphery of the speaker unit 203, and in the thickness direction of the headphone unit 1002, the battery 30 and the speaker unit 203 share the thickness space of the ear shell 10. This helps to reduce the overall thickness of the headphone unit 1002, achieving a thinner and lighter headphone unit 1002.

[0038] Specifically, the speaker bracket 202 has an annular flange 2022 to form a ring structure. The outer peripheral wall of the flange 2022 and the speaker bracket 202 facing the back of the ear shell 10 form an annular notch, which constitutes a receiving groove 201, thereby accommodating the annular battery 30 outside the speaker assembly 20. The battery 30 is annularly arranged, with its inner peripheral side fitted onto the outer peripheral side of the flange 2022. The battery 30 is fixed to the flange 2022. With this arrangement, the battery 30 and the speaker unit 203 share a thickness space in the thickness direction of the headphone unit 1002, thereby reducing the overall thickness of the headphone unit 1002, making the headphone unit 1002 thinner and lighter. It also helps to improve the structural compactness between the battery 30 and the speaker assembly 20, thereby improving the structural compactness of the single unit of the headphone 100.

[0039] In some embodiments of this application, the battery 30 includes at least two batteries connected in series. Each battery 30 is arranged in an arc shape, and the at least two batteries 30 are distributed circumferentially at intervals along the receiving groove 201, so that the battery 30 as a whole can form a ring structure. Compared with an integrated battery 30, the battery 30 has a split structure, which helps to improve the flexibility of arrangement. Moreover, the series connection between multiple batteries 30 can provide a stable high-voltage direct current to enhance the magnetic field strength of the magnetic gap 2035. This helps to increase the driving force of the voice coil 2032, thereby optimizing the vibration of the diaphragm 2031, thereby reducing sound distortion, improving detail and low-frequency performance, and achieving improved sound quality.

[0040] In some embodiments of this application, the headphones 100 further include a flexible circuit board 40, with the battery 30 and speaker assembly 20 all electrically connected to the flexible circuit board 40, which is disposed on one side of the speaker assembly 20 in the circumferential direction. Compared to the conventional design where the battery 30 and the flexible circuit board 40 are simply stacked in the thickness direction of the headphone unit 1002, the battery 30 is offset and arranged side-by-side with the flexible circuit board 40 in the radial direction of the headphone unit 1002. This allows for full utilization of the internal space of the ear shell 10, resulting in a relatively smaller size of the headphone unit 1002 in the thickness direction. This reduces the thickness of the headphone unit 1002, making the overall thickness of the headphone unit 1002 smaller, resulting in a thinner and lighter headphone 100, avoiding a bulky product design, and thus making it more comfortable to wear.

[0041] Please refer to Figures 1 to 5In some embodiments of this application, the headset 100 further includes an earcup assembly 50 connected to the speaker bracket 202 along its thickness direction. The earcup assembly 50 includes an earcup bracket 501, an earcup body 502, and earcup foam 503.
