Description

Technical Field

[0001] This application belongs to the field of headphone device technology, and more specifically, relates to a headphone battery compartment structure and a headphone. Background Technology

[0002] In existing headphone designs, the battery, as a crucial component, is typically integrated inside the headphones to provide a continuous power supply. However, with increasing user demands for headphone use, battery replacement and maintenance have become significant issues. Traditional headphone battery designs usually seal the battery inside the headphones, making it difficult or impossible to replace, thus shortening the product's lifespan.

[0003] To address this issue, some headphone designs incorporate removable batteries, allowing users to replace them themselves. However, current removable battery designs involve a tail cap on the headphone, which is opened to remove the battery from its housing. Yet, to minimize headphone size and ensure battery stability, manufacturers have kept the gap between the battery and the housing very small, making it difficult to remove the battery by hand from the narrow space, causing inconvenience for users. Utility Model Content

[0004] The purpose of this application is to provide an earphone battery compartment structure and earphones to solve the technical problem that earphone batteries are not easy to replace in the prior art.

[0052] Current headphone products with removable batteries use a removable tail cap design to allow users to replace the battery. However, to ensure battery stability and structural simplicity, a retaining cavity is usually used to limit the headphone's movement and prevent it from shaking. This means that even after removing the tail cap, the battery is difficult to remove directly from the narrow retaining cavity, requiring tools or force to shake it out, increasing the complexity and inconvenience for users when replacing the battery.

[0053] Therefore, please refer to the earphone battery compartment structure provided in this application embodiment. Figures 1-3The headphone battery compartment structure includes: a battery compartment inner shell 4 having a first receiving groove 412, the first receiving groove 412 having a first opening 41 facing a first direction and a second opening 42 facing a second direction, the first direction and the second direction being non-parallel; a battery compartment outer cover 5 having a second receiving groove 58, the second receiving groove 58 having a third opening 51 facing the opposite direction of the first direction and a fourth opening 52 facing the opposite direction of the second direction; the battery compartment outer cover 5 covers the battery compartment inner shell 4, and the first opening 41 and the third opening 51 are arranged opposite to each other, the second opening 42 and the fourth opening 52 are arranged opposite to each other, so that the first receiving groove 412 and the second receiving groove 58 form a receiving cavity; and a battery 3 located in the receiving cavity.

[0054] See Figure 3 In this embodiment, the first direction and the second direction are perpendicular. It is easy to understand that the first direction and the second direction can also be other non-perpendicular angular relationships, as long as the first opening 41 and the third opening 51 are set opposite each other, and the second opening 42 and the fourth opening 52 are set opposite each other, it will not affect the formation and use of the receiving cavity. The specific angle can be adjusted according to the actual design requirements.

[0055] See Figure 3 The first opening 41 and the second opening 42 form a continuous open space, and the third opening 51 and the fourth opening 52 form a continuous open space. When the inner shell 4 of the battery compartment and the outer cover 5 of the battery compartment are fastened together, part of the battery is located in the first receiving groove 412, and the remaining part of the battery 3 is located in the second receiving groove 58. The first receiving groove 412 and the second receiving groove 58 form a closed receiving cavity.

[0056] This embodiment of the application provides a first receiving groove 412 in the inner shell 4 of the battery compartment and a second receiving groove 58 in the outer cover 5 of the battery compartment. The first receiving groove 412 and the second receiving groove 58 have opposing openings, so that after removing the outer cover 5 from the inner shell 4, the battery 3 can be taken out from the first opening 41 and the third opening 51, making the battery installation and removal process more convenient. Even if the battery 3 is tightly fitted inside the receiving cavity, the user can easily remove the battery 3 without additional tools, making it convenient for the user to replace the battery 3. This headphone battery compartment structure not only improves the user experience and reduces the difficulty of replacing the battery, but also extends the service life of the headphones, meeting the user's needs for the convenience and maintainability of the headphones. In addition, the design of this headphone battery compartment structure also helps to maintain the compactness and aesthetics of the headphones, ensuring that the stability of the battery 3 is not affected while miniaturizing the size.

[0057] As an optional implementation, the outer cover 5 of the battery compartment and the inner shell 4 of the battery compartment are connected by a snap-fit.

[0058] Specifically, the battery compartment outer cover 5 and the battery compartment inner shell 4 have a first latching structure and / or a second latching structure; the first latching structure is used to prevent the battery compartment outer cover 5 from moving in a first direction, and the second latching structure is used to prevent the battery compartment outer cover 5 from moving in a second direction.

[0059] Optional, see Figures 4-6 The first snap-fit ​​structure includes a first male snap-fit ​​54 and a first female snap-fit ​​48 that are compatible with each other; the end face of the inner shell 4 of the battery compartment facing the first direction is provided with a first step 410, and the end face of the outer cover 5 of the battery compartment facing the opposite direction of the first direction is provided with a second step 57, and the first step 410 and the second step 57 are fitted together; one of the first male snap-fit ​​54 and the first female snap-fit ​​48 is provided on the first step 410, and the other of the first male snap-fit ​​54 and the first female snap-fit ​​48 is provided on the second step 57.

[0060] See Figures 4-6 In one embodiment, the first step 410 is positioned close to the battery 3, and the second step 57 is positioned away from the battery 3. In another embodiment, the first step 410 is positioned away from the battery 3, and the second step 57 is positioned close to the battery 3 (not shown in the figure). The first step 410 and the second step 57 engage with each other, preventing the battery compartment cover 5 from moving upward in a third direction, where the third direction refers to a direction perpendicular to the first and second directions.

[0061] It is easy to understand that a first male buckle 54 can be set on the first step 410, and a first female buckle 48 can be set on the second step 57; or, a first female buckle 48 can be set on the first step 410, and a first male buckle 54 can be set on the second step 57.

[0062] Optionally, the number of first male buckles 54 can be 2 to 6, and the number of first female buckles 48 is the same as the number of first male buckles 54, also 2 to 6. See also Figures 4-6 In this embodiment, four of each of the first male buckle 54 and the first female buckle 48 are provided.

[0063] See Figures 4-5 The first female buckle 48 has a chamfered groove; see also Figure 6 The first male buckle 54 has a chamfered protrusion. The engagement of the first female buckle 48 and the first male buckle 54 forms a secure first snap-fit ​​structure. See also... Figure 3 When the first male buckle 54 and the first female buckle 48 are engaged, the first buckle structure can prevent the battery compartment cover 5 from moving in the first direction.

[0064] Optionally, the second snap-fit ​​structure includes a matching second male snap-fit ​​55 and a second female snap-fit ​​49; the second male snap-fit ​​55 is disposed on the end face of the outer cover 5 of the battery compartment facing the opposite direction of the second direction, and the second female snap-fit ​​49 is disposed on the inner wall of the inner shell 4 of the battery compartment.

[0065] Optionally, the second male buckle 55 can be set to 1 to 3, and the number of the second female buckles 49 is the same as that of the second male buckle 55, also set to 1 to 3. See also Figures 6-7 In this embodiment, one second male buckle 55 and one second female buckle 49 are provided.

[0066] See Figure 6 The second male buckle 55 has a chamfered protruding structure; see also Figure 7 The second female buckle 49 has a chamfered groove. The engagement of the second male buckle 55 and the second female buckle 49 forms a secure second snap-fit ​​structure. See also... Figure 3 When the second male buckle 55 and the second female buckle 49 are engaged, the second buckle structure effectively prevents the battery compartment cover 5 from moving in the second direction.

[0067] As an optional implementation, see [link to implementation details]. Figures 3-4 The inner shell 4 of the battery compartment is provided with an extension 411 extending in the second direction at one end near the outer cover 5 of the battery compartment. In the closed state, the outer side wall of the extension 411 is in contact with the inner side wall of the outer cover 5 of the battery compartment.

[0068] Optionally, the outer wall of the inner shell 4 of the battery compartment is flush with the outer wall of the outer cover 5 of the battery compartment, making the product more aesthetically pleasing.

[0069] This embodiment, through the design of the extension, enhances the sealing performance, preventing dust and moisture intrusion and further ensuring the safety and stability of the battery compartment structure. Furthermore, the design of the extension 411 also improves the overall structural strength of the battery compartment structure. (See [link to previous section]). Figures 8-9 The second male buckle 55 and the second female buckle 49 fasten together, and the extension 411 fits tightly with the outer cover 5 of the battery compartment. They are located diagonally opposite the battery 3, thus forming a stable structure. This prevents the outer cover 5 of the battery compartment from easily loosening, and the outer cover 5 of the battery compartment can only be opened in the second direction, ensuring the safety and durability of the battery compartment structure.

[0070] See Figure 4 The first step 410 has a first sliding end face 47; see also Figure 6 The second step 57 has a second sliding end face 53. See also Figure 3When installing battery 3, battery 3 is placed in the first receiving slot 412. Then, the first opening 41 of the inner shell 4 of the battery compartment is aligned with the third opening 51 of the outer cover 5 of the battery compartment. The outer cover 5 of the battery compartment is pushed to slide in the opposite direction of the second direction. During the sliding process, the first sliding end face 47 contacts the second sliding end face 53. When the first male buckle 54 and the first female buckle 48 are fully engaged, the second male buckle 55 and the second female buckle 49 are also engaged simultaneously, thus completing the installation of the outer cover 5 of the battery compartment. After installation, the outer cover 5 of the battery compartment is firmly fixed in the first, second, and third directions, which can effectively improve the overall structural stability and reliability of the battery compartment structure, prevent the outer cover 5 of the battery compartment from being accidentally opened or displaced, and improve the safety and service life of the equipment.

[0071] See Figure 3 When it is necessary to remove the battery 3, hold the inner shell 4 of the battery compartment with one hand and pull the outer cover 5 of the battery compartment in the second direction with the other hand. When the first male buckle 54 separates from the first female buckle 48, the second male buckle 55 and the second female buckle 49 also separate. The outer cover 5 of the battery compartment moves out smoothly. At this time, the side and one end of the battery 3 are presented to the user. The user can easily take out the battery 3. The operation is simple and safe.

[0072] As an optional implementation method, see [link to implementation details]. Figure 5 , Figure 7 The inner shell 4 of the battery compartment has a recessed arc surface 46 on its outer side wall in the opposite direction to the first direction. By designing the recessed arc surface 46, a more comfortable grip is provided when installing or removing the outer cover 5 of the battery compartment, reducing finger slippage and improving the user experience. The recessed arc surface 46 conforms to the natural curvature of the fingers, allowing the user's fingers to fit comfortably, increasing grip stability and reducing operational difficulty. It is easy to understand that a recessed arc surface 46 can also be provided on the outer side wall of the outer cover 5 in the first direction to further enhance grip comfort, ensuring good fit for both fingers during operation and improving ease of use.

[0073] As an optional implementation method, see [link to implementation details]. Figures 8-9 A circuit board 2 is also installed inside the housing cavity, and the circuit board 2 is electrically connected to the battery 3. By placing the circuit board 2 in the housing cavity, the integration of the headphones can be effectively improved.

[0074] For details, see Figure 9 A positive electrode spring 6 and a negative electrode spring 7 are soldered onto circuit board 2. The positive electrode 31 and negative electrode 32 of battery 3 are located at the same end. The positive electrode spring 6 contacts the positive electrode 31 of battery 3, and the negative electrode spring 7 contacts the negative electrode 32 of battery 3, thus achieving circuit conduction. By placing the positive electrode 31 and negative electrode 32 of battery 3 at the same end, the integration of the headphones can be further improved, and the difficulty of battery installation can be reduced.

[0075] Optionally, the battery in this embodiment can be a cylindrical battery, a rectangular battery, a trapezoidal battery, etc., and the shape of the receiving cavity is the same as the shape of the battery.

[0076] See Figure 10 The circuit board 2 is also provided with a limiting groove 21, see [reference]. Figure 7 The inner shell 4 of the battery compartment is provided with a limiting plane 45 that contacts the circuit board 2. The limiting plane 45 is provided with a limiting post 44 that matches the limiting groove 21. By locking the limiting groove 21 onto the limiting post 44 and abutting the circuit board 2 against the limiting plane 45, the circuit board 2 can be stably fixed, preventing it from shifting during the use of the earphone and avoiding poor contact with the battery 3 due to vibration.

[0077] See Figure 6 , Figure 9 Inside the battery compartment cover 5, there is a limiting block 56 that contacts one end of the battery 3. This limiting block 56 can limit the battery 3, prevent it from shaking inside the compartment, and ensure good contact between the battery 3 and the circuit board 2.

[0078] This embodiment also discloses an earphone, including the earphone battery compartment structure described in any of the above embodiments. The earphone can be an open-back earphone, over-ear earphone, in-ear earphone, Bluetooth earphone, bone conduction earphone, etc.

[0079] For example, see Figures 1-3 The headphones are open-back headphones, and an ear hook 1 is fixed on the inner shell 4 of the battery compartment. One end of the inner shell 4 of the battery compartment has a connecting part 43 for embedding the ear hook 1. The connecting part 43 is provided with a wire hole 431. The wires of the circuit board 2 pass through the wire hole 431 and the ear hook 1 to connect with components such as the speaker.
