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 headphone to provide a continuous power supply. However, with increasing user demands for headphone performance, battery replacement and maintenance have become significant issues. Traditional headphone battery designs connect the battery to the PCB via solder wires. Solder wire assembly is difficult, the solder joints occupy considerable PCB space, limiting the headphone's size, and the non-removable battery restricts the headphone's lifespan and user convenience. To address this problem, some headphone designs have adopted removable batteries, allowing users to replace them themselves.
[0003] While removable batteries offer convenience, this design introduces new challenges in practical applications. Because the battery needs to be removed and reinstalled from the headphones, a specialized foolproof mechanism must be incorporated inside the headphones to ensure proper battery installation and securement, thereby preventing damage to headphone components or performance degradation due to incorrect installation.
[0004] Existing foolproof design features a variety of patterns, but they typically require additional components and complex assembly processes. This not only increases the manufacturing cost of the headphones but also leads to larger headphone size and more complex design. Furthermore, some foolproof designs are not intuitive enough, which may confuse users when replacing batteries, increasing the difficulty of operation. Utility Model Content
[0005] The purpose of this application is to provide an earphone battery compartment structure and earphones, so as to solve the technical problems in the prior art where earphones with removable batteries require specially designed foolproof structures, which increases the manufacturing cost of earphones, as well as the increase in the size of earphones and the complexity of their design.
[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: Firstly, an earphone battery compartment structure is provided, comprising:
[0007] Warehouse body;
[0008] A battery cover is detachably mounted on the housing, and the housing and the battery cover form a receiving cavity;
[0009] A circuit board is located within the receiving cavity, and a first electrical connector and a second electrical connector are provided on the circuit board;
[0010] A cylindrical battery is located within the receiving cavity. The positive and negative terminals of the cylindrical battery are both located at the first end of the cylindrical battery, with the positive terminal located at the middle of the first end and the negative terminal being annular. The first electrical connector is in contact with the positive terminal of the cylindrical battery, and the second electrical connector is in contact with the negative terminal of the cylindrical battery.
[0011] This embodiment sets the positive and negative terminals of the cylindrical battery at the same end, with the positive terminal in the middle and the negative terminal in a ring shape. This eliminates the need for a foolproof structure for the cylindrical battery. Users can insert the cylindrical battery into the receiving cavity at any angle, and the two electrical connectors will automatically align the positive and negative terminals, simplifying the installation process and improving the user experience.
[0012] As an alternative implementation of the first aspect, a portion of the cylindrical battery is located within the receiving cavity corresponding to the battery cover.
[0013] This embodiment allows the cylindrical battery portion to protrude outside the battery casing, making it easy for the user to remove the cylindrical battery using their fingers or tools when the battery cover is removed.
[0014] As an alternative implementation of the first aspect, the housing is part of the earphone housing, or the housing is part of the earphone hook housing, or the housing is a battery housing disposed within the earphone housing or the earphone hook housing.
[0015] This application provides various housing integration methods to adapt to the needs of different headphone structures. When the housing is part of the headphone shell, it simplifies the structural design; when it is part of the headphone hook shell, it can increase the battery capacity without affecting the headphone body; when it is a separate battery shell, it facilitates maintenance and replacement, and provides better protection for the cylindrical battery and circuit board.
[0016] As an alternative implementation of the first aspect, the circuit board is disposed within the compartment, with the first electrical connector and the second electrical connector facing the battery cover.
[0017] In this embodiment, by placing the circuit board inside the housing, the circuit board is located deep within the cavity, thus making the circuit board less susceptible to damage and also shortening the length of the wire connecting the headphone speaker and the circuit board.
[0018] As an alternative implementation of the first aspect, the circuit board is disposed inside the battery cover, with the first electrical connector and the second electrical connector facing the compartment.
[0019] This embodiment simplifies the structure of the battery compartment by integrating the circuit board inside the battery cover, while also facilitating the maintenance and replacement of the circuit board.
[0020] As an optional implementation of the first aspect, a first positioning boss is provided in the receiving cavity corresponding to the compartment or the receiving cavity corresponding to the battery cover to prevent the circuit board from rotating along the axial direction of the cylindrical battery, and a first limiting groove is provided on the circuit board to cooperate with the first positioning boss.
[0021] This embodiment, by setting a first positioning boss and a first limiting groove, can prevent the circuit board from rotating during the use of the headphones, thereby improving the stability and service life of the circuit board.
[0022] As an optional implementation of the first aspect, a first limiting boss is further provided in the receiving cavity corresponding to the compartment or the receiving cavity corresponding to the battery cover to prevent the circuit board from moving along the axial direction of the cylindrical battery, and a first limiting end face is provided on the circuit board to abut against the first limiting boss.
[0023] This embodiment, by setting a first limiting boss and a first limiting end face, can prevent the circuit board from displacing axially when subjected to vibration or external force.
[0024] As an optional implementation of the first aspect, a second limiting boss is provided on the inner side wall of the battery cover to limit the end face of the compartment body near the battery cover. A portion of the second limiting boss protrudes along the axial direction of the cylindrical battery to form a second positioning boss. A first positioning groove is provided at the end of the compartment body near the battery cover to cooperate with the second positioning boss.
[0025] This embodiment achieves precise positioning of the battery cover and the compartment body through the cooperation of the second positioning boss and the first positioning groove, thereby improving the assembly accuracy between the battery cover and the compartment body and avoiding assembly difficulties or poor connection caused by misalignment.
[0026] As an optional implementation of the first aspect, a first groove is also provided on the inner sidewall of the battery cover, the first groove extending from the second positioning boss to the end face of the battery cover near the compartment body.
[0027] In this embodiment, a first groove is provided. When the user closes the battery cover, he / she only needs to align the first positioning groove with the first groove to achieve alignment between the first positioning groove and the second positioning protrusion, thereby improving the convenience of user operation.
[0028] As an optional implementation of the first aspect, the first electrical connector is a positive electrode spring and the second electrical connector is a negative electrode spring.
[0029] In this embodiment, the elasticity of the springs allows the positive and negative springs to automatically contact the positive and negative electrodes during cylindrical battery installation, ensuring good contact.
[0030] As an alternative implementation of the first aspect, the compartment is threaded or snapped onto the battery cover.
[0031] In this embodiment, the battery cover can be easily removed by threading or snapping the compartment body to the battery cover.
[0032] In a second aspect, an earphone is provided, including an earphone battery compartment structure as described in any one of the first aspects.
[0033] The beneficial effects of this embodiment are as follows: By designing a removable battery cover, users can easily replace the cylindrical battery. By placing the positive and negative terminals of the cylindrical battery at the same end, with the positive terminal in the center and the negative terminal in a ring shape, there is no need to design a foolproof structure for the cylindrical battery. Users can insert the cylindrical battery into the receiving cavity at any angle, and the two electrical connectors will automatically align the positive and negative terminals, simplifying the installation process and improving the user experience. Furthermore, since the positive and negative terminals are designed at the same end of the cylindrical battery, the space occupied by the circuit board can be reduced, allowing the headphones to be made smaller and improving their portability.

[0056] Please refer to the following: Figure 1 and Figure 2The headphone battery compartment structure provided in this application embodiment will now be described. The headphone battery compartment structure includes: a compartment body; a battery cover 6, detachably mounted on the compartment body, the compartment body and the battery cover 6 forming a receiving cavity 8; a circuit board 2, located within the receiving cavity 8, the circuit board 2 being provided with a first electrical connector and a second electrical connector; a cylindrical battery 1, located within the receiving cavity 8, the positive electrode 11 and the negative electrode 12 of the cylindrical battery 1 being located at the first end of the cylindrical battery 1, with the positive electrode 11 located at the middle of the first end, and the negative electrode 12 of the cylindrical battery 1 being annular; the first electrical connector is in contact with the positive electrode 11 of the cylindrical battery 1, and the second electrical connector is in contact with the negative electrode 12 of the cylindrical battery 1.
[0057] Specifically, the cavity 8 is cylindrical and matches the shape of the cylindrical battery 1.
[0058] See Figure 3 The first end of the cylindrical battery 1 is circular, with the positive electrode 11 located in the middle of the first end. The negative electrode 12 is annular, and the center of the negative electrode 12 is the same as the center of the first end. An insulating ring 13 is provided between the positive electrode 11 and the negative electrode 12. The insulating ring 13 can be made of plastic to prevent short circuits between the positive and negative electrodes.
[0059] See Figure 4 The circuit board 2 is equipped with a first electrical connector and a second electrical connector, corresponding to the positive terminal 11 and negative terminal 12 of the cylindrical battery 1, respectively, to ensure a stable connection. Optionally, the first electrical connector is a positive terminal spring 11, and the second electrical connector is a negative terminal spring 12. The springs are elastic, and their elasticity allows them to automatically abut against the positive and negative terminals during installation of the cylindrical battery 1, ensuring good contact. Specifically, the circuit board 2 can be a PCB or a PCBA.
[0060] See Figure 5 The positive electrode 11 of the cylindrical battery 1 is positioned opposite to the first electrical connector of the circuit board 2, and the negative electrode 12 is positioned opposite to the second electrical connector.
[0061] This embodiment features a removable battery cover 6, allowing users to easily replace the cylindrical battery 1. By placing the positive terminal 11 and negative terminal 12 of the cylindrical battery 1 at the same end, with the positive terminal 11 in the center and the negative terminal 12 in a ring shape, there is no need to design a foolproof structure for the cylindrical battery 1. Users can insert the cylindrical battery 1 into the receiving cavity 8 at any angle, and the two electrical connectors will automatically align with the positive and negative terminals, simplifying the installation process and improving the user experience. Furthermore, since the positive terminal 11 and negative terminal 12 are designed at the same end of the cylindrical battery 1, the space occupied by the circuit board 2 can be reduced, allowing the headphone to be made smaller and improving its portability.
[0062] The installation process of the headphone battery compartment structure in this embodiment is as follows: First, assemble and fix the circuit board 2 in the compartment. Then, assemble the cylindrical battery 1 in the compartment, with the negative electrode 12 and positive electrode 11 contacting the negative electrode spring 4 and positive electrode spring 3 respectively. Next, assemble the battery cover 6 to press down the cylindrical battery 1. The negative electrode spring 4 and positive electrode spring 3 can be compressed by 0.4mm, and the cylindrical battery 1 becomes conductive and receives power. The entire battery assembly process does not require soldering wires or plugging connectors, making assembly convenient and efficient.
[0063] As one optional implementation, the housing is part of the headphone shell, which can be the shell of an in-ear headphone or a headphone, etc. As another optional implementation, the housing is part of the headphone hook shell 7, which is the shell of an ear-hook headphone. As yet another optional implementation, see [link to further details]. Figure 2 The housing is a separate battery casing 5, which is located inside the earphone casing or the earphone hook casing 7.
[0064] This application provides various housing integration methods to adapt to the needs of different headphone structures. For example, when the housing is part of the headphone shell, it simplifies the structural design; when it is part of the headphone hook shell 7, it can increase the battery capacity without affecting the headphone body; when it is an independent battery shell 5, it facilitates maintenance and replacement, and provides better protection for the cylindrical battery 1 and circuit board 2.
[0065] As an optional implementation method, see [link to implementation details]. Figure 6 Some of the cylindrical batteries 1 are located in the receiving cavity 8 corresponding to the compartment (i.e., battery casing 5), and some of the cylindrical batteries 1 are located in the receiving cavity 8 corresponding to the battery cover 6.
[0066] In other words, the length of the cylindrical battery 1 is greater than the depth of the corresponding receiving cavity 8 of the battery casing 5, and part of the cylindrical battery 1 protrudes outside the battery casing 5. When the user removes the battery cover 6, since part of the cylindrical battery 1 is outside the battery casing 5, it is easy for the user to remove the cylindrical battery 1 with their fingers or tools (such as tweezers). This design not only facilitates user operation but also enhances the flexibility of battery replacement. Optionally, the exposed part of the cylindrical battery 1 can also be designed with an anti-slip texture to increase friction and ensure a more stable installation or removal of the cylindrical battery 1.
[0067] See Figure 6 , Figure 7The battery housing 5 is disposed inside the headphone hook housing 7. Optionally, the headphone hook housing 7 has a third limiting protrusion 71 at one end near the battery cover 6, and the battery housing 5 has a second limiting end face 54 at one end near the battery cover 6 that abuts against the third limiting protrusion 71, so that the battery housing 5 is stably positioned inside the headphone hook housing 7. Optionally, the headphone hook housing 7 is made of silicone, and the battery housing 5 is made of plastic. The two are injection molded together, resulting in a sturdy structure and good shock absorption.
[0068] As an optional implementation method, see [link to implementation details]. Figure 6 The circuit board 2 is located inside the battery housing 5, with the first electrical connector and the second electrical connector facing the battery cover 6.
[0069] By placing the circuit board 2 inside the battery housing 5, it is positioned deep within the receiving cavity 8, thus reducing the risk of damage to the circuit board 2 and shortening the length of the wire connecting the headphone speaker to the circuit board 2. The wire passes through a wire hole 55 at the end of the battery housing away from the battery cover.
[0070] See Figure 4 , Figure 8 Corresponding to the embodiment in which the circuit board 2 is disposed within the battery housing 5, the corresponding receiving cavity 8 of the battery housing 5 is provided with a means to prevent the circuit board 2 from moving along the axial direction of the cylindrical battery 1. Figure 3 The dotted line in the diagram represents the first positioning boss 51 that rotates axially (the first positioning boss 51) on the cylindrical battery 1. The circuit board 2 is provided with a first limiting groove 21 that cooperates with the first positioning boss 51.
[0071] By providing a first positioning protrusion 51 inside the battery housing 5 and a first limiting groove 21 on the circuit board 2, the circuit board 2 can be prevented from rotating during the use of the headphones, thereby improving the stability and service life of the circuit board 2.
[0072] See Figure 6 , Figure 8 In the embodiment where the circuit board 2 is placed inside the battery housing 5, the corresponding receiving cavity 8 of the battery housing 5 is also provided with a first limiting boss 52 to prevent the circuit board 2 from moving along the axial direction of the cylindrical battery 1, and the circuit board 2 is provided with a first limiting end face 22 that abuts against the first limiting boss 52.
[0073] By setting a first limiting protrusion 52 inside the chamber and a first limiting end face 22 on the circuit board 2, plus the elastic force provided by the positive electrode spring 3 and the negative electrode spring, the circuit board 2 can be prevented from displacing axially when subjected to vibration or external force.
[0074] As an alternative implementation, the circuit board is disposed inside the battery cover, with the first electrical connector and the second electrical connector facing the battery housing (not shown in the figure).
[0075] By integrating the circuit board inside the battery cover, the structure of the compartment can be simplified, while also facilitating the maintenance and replacement of the circuit board. In this embodiment, wires are provided on the battery cover and inside the compartment, and the wires automatically connect when the battery cover is closed to the battery housing.
[0076] In the embodiment where the circuit board is housed in the battery cover, a first positioning boss (not shown in the figure) is provided in the receiving cavity corresponding to the battery cover to prevent the circuit board from rotating along the axial direction of the cylindrical battery, and a first limiting groove is provided on the circuit board to cooperate with the first positioning boss. This prevents the circuit board from rotating during the use of the earphones.
[0077] Corresponding to the embodiment where the circuit board is placed in the battery cover, a first limiting boss (not shown in the figure) is also provided in the receiving cavity of the battery cover to prevent the circuit board from moving axially along the cylindrical battery. The circuit board is provided with a first limiting end face that abuts against the first limiting boss. This prevents the circuit board from displacing axially when subjected to vibration or external force.
[0078] As an optional implementation method, see [link to implementation details]. Figure 9 , Figure 10 The inner wall of the battery cover 6 is provided with a second limiting protrusion 62 that limits the end face of the battery housing 5 near the end of the battery cover 6. A portion of the second limiting protrusion 62 protrudes along the axial direction of the cylindrical battery 1 to form a second positioning protrusion 63. The end of the compartment near the battery cover 6 is provided with a first positioning groove 53 that cooperates with the second positioning protrusion 63.
[0079] By cooperating with the second positioning boss 63 and the first positioning groove 53, the battery cover 6 and the battery housing 5 can be accurately positioned, improving the assembly accuracy between the battery cover 6 and the compartment and avoiding assembly difficulties or poor connection caused by misalignment.
[0080] As an optional implementation method, Figure 10 The inner wall of the battery cover 6 is also provided with a first groove 64, which extends from the second positioning boss 63 to the end face of the battery cover 6 near the battery housing 5.
[0081] Because the battery cover 6 has a certain depth, and the second positioning protrusion 63 is located in the middle of the battery cover 6 along the depth direction, if the first groove 64 is not provided, the user may not be able to see the second positioning protrusion 63 when closing the battery cover 6, which could lead to unsuccessful closing due to the first positioning groove 53 not being aligned with the second positioning protrusion 63. If the first groove 64 is provided, the user only needs to align the first positioning groove 53 with the first groove 64 when closing the battery cover 6, thus achieving alignment between the first positioning groove 53 and the second positioning protrusion 63, improving the convenience of user operation.
[0082] As an optional implementation method, Figure 9 , Figure 10 The compartment body and the battery cover 6 are engaged. Specifically, a latch 56 (i.e., a latching tooth) is provided on the outer wall of the compartment body near the battery cover 6, and a slot 61 is provided on the inner wall of the battery cover 6. The latch 56 on the compartment body and the slot 61 on the battery cover 6 cooperate with each other to form a stable engagement structure. This structure not only ensures the stability of the battery cover 6 in the closed state, but also effectively prevents the battery cover 6 from being accidentally opened when subjected to external force.
[0083] As an alternative implementation, the compartment body is threadedly connected to the battery cover 6 (not shown in the figure). Specifically, an external thread can be provided on the outer side wall of the compartment body near the battery cover 6, while a corresponding internal thread is provided on the inner side wall of the battery cover 6. The connection between the battery cover 6 and the compartment body is achieved by tightening.
[0084] This application also discloses an earphone, which can be an open-back earphone, a headphone, an in-ear earphone, a Bluetooth earphone, a bone conduction earphone, etc. The earphone includes the battery compartment structure described above.
