[0002] Headphones typically connect the battery pack and other components (such as the transducer) to the headphone via wires in the ear hook, allowing the battery pack to power the other components. The wires extend from the ear hook and are soldered to a circuit board within the battery pack to establish the electrical connection. However, because the wires are soldered to the circuit board, they are essentially connected via soldered wires.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0038] Headphones are common audio devices used for personal entertainment and communication. A typical headphone consists of ear hooks, a battery assembly, a transducer assembly, and other related circuit components. The ear hook is a component on the headphone designed to fit the shape of the ear, facilitating a comfortable fit and maintaining stability. Inside the ear hook are usually wires that connect the battery assembly to the transducer assembly and other related circuit components, enabling the transmission of power or signals. Specifically, one end of the wire connects to the transducer assembly within the ear hook, such as a speaker unit, while the other end connects to the battery assembly to complete the circuit, allowing the battery assembly to power other components (such as the transducer assembly). The battery assembly, as the headphone's power source, contains one or more batteries and at least one circuit board. The circuit board is designed to manage and distribute power, ensuring the proper functioning of other components. After extending from the ear hook, the wires must be secured to the circuit board of the battery assembly to establish the electrical connection. This is typically achieved by soldering, where the ends of the wires are securely soldered to specific solder points on the circuit board using solder wires. The solder joint forms a solder line, which acts as a connecting medium, allowing the conductors to fuse with the circuit board and ensuring smooth current flow. This connection method is reliable under normal circumstances because it provides a low-resistance path and prevents accidental detachment. However, the solder line itself is relatively fragile because, although tiny, it easily becomes a stress concentration point when subjected to force. More specifically, when the headphones are subjected to external forces, such as being accidentally dropped, the impact force is transmitted from different parts of the headphones to the solder joint. For example, if the headphones are dropped from a height onto a hard surface, the anchor point of the conductor will be stretched due to acceleration or impact, causing the solder line to be subjected to excessive tension. Because the solder line is located between the end of the conductor and the circuit board, this tension may act directly on the solder line. The conductor itself may not break immediately, but the solder line, due to its small size and low strength, often cracks or breaks before other parts. Once the solder line breaks, the circuit of the conductor is interrupted, and current cannot flow from the battery assembly to other components of the headphones. The battery assembly should be providing power, but due to the interruption of the electrical connection, the transducer cannot receive the necessary power, causing the headphones to malfunction completely. Users may find that the device is unresponsive, unable to play sound or process signals, requiring repair or replacement. Therefore, improving the existing design where the wires in the ear hook are directly soldered to the circuit board of the battery assembly to avoid the need for soldering wires to establish electrical connections between the wires and the circuit board, thus allowing the headphones to withstand greater external impacts without damage, has become a pressing problem for those skilled in the art. To address these issues, this application provides a battery assembly 100 (e.g., Figure 1 as well as Figure 2 (as shown) and headphones 1000 (as shown) Figure 1 (As shown).

[0039] Please see Figure 1 , Figure 2 and Figure 3 The battery assembly 100 of this application includes a battery case 10 and a circuit board assembly 20. The circuit board assembly 20 is at least partially housed within the battery case 10. The circuit board assembly 20 includes a first circuit board 21 and a connector 22. The connector 22 is disposed on one side of the first circuit board 21 and configured to be inserted into an electrical connector 60 inside the ear hook 200 so that the electrical connector 60 is electrically connected to the first circuit board 21.

[0040] Specifically, battery assembly 100 refers to the integrated functional component in the headphones 1000 that provides power to the entire headphones 1000. Battery assembly 100 is the core unit for the energy supply of the headphones 1000. It includes not only the energy storage unit (power supply unit 40) but also its associated control, protection, and interface components (such as the first circuit board 21 and connector 22). Battery assembly 100 can be designed as an independently packaged structure, responsible for converting chemical energy into electrical energy and stably delivering power to other components of the headphones 1000 (such as the transducer assembly 300) through internal circuitry. The core function of battery assembly 100 is to ensure the continuous, reliable, and safe operation of the headphones 1000.

[0041] Specifically, the battery assembly 100 includes a circuit board assembly 20 and a battery casing 10, wherein the battery casing 10 refers to a rigid or semi-rigid outer cover structure that encloses and protects the battery assembly 100. In this application, the battery casing 10 may be made of high-strength plastic, metal alloy, or composite material. As a barrier protecting the circuit board assembly 20, the battery casing 10 can be used to resist environmental factors such as external impacts, compression, dust, and moisture that may damage the internal circuitry.

[0042] Specifically, the circuit board assembly 20 refers to an electronic functional component installed inside the battery casing 10 of the battery assembly 100, with the first circuit board 21 as its physical carrier. The circuit board assembly 20 is not a single component, but an electrical assembly integrating various electronic components (such as resistors, capacitors, integrated circuit chips, etc.) and interface components (such as connectors 22). The circuit board assembly 20 can be used for voltage regulation, filtering, charge / discharge control, overload protection, and short-circuit protection of the electrical energy input to the headphone 1000 battery, and can also perform audio signal processing and wireless communication functions. Through the connectors 22 carried on the first circuit board 21, the circuit board assembly 20 can establish electrical interconnection paths with other functional modules of the headphone 1000 (especially the ear hook 200 assembly).

[0043] Specifically, the circuit board assembly 20 includes a first circuit board 21 and a connector 22. The first circuit board 21 is a rigid or flexible circuit substrate that serves as the main carrier and plays a leading role in the circuit board assembly 20. The first circuit board 21 is the physical core and functional platform of the circuit board assembly 20. The first circuit board 21 can form an electrical signal and power transmission network connecting various electronic components by etching precision copper foil traces (conductors) on its surface. The first circuit board 21 can also have various active / passive electronic components mounted on its surface or inserted through through-holes on its surface.

[0044] Specifically, connector 22 refers to an electrical interface device that is fixedly mounted (e.g., by soldering) to a specific side area of ​​the first circuit board 21. Connector 22 is the core component for enabling pluggable electrical connections. Connector 22 is precisely designed to physically mate and lock with specific complementary electrical connectors 60 inside ear hook 200 to form a reliable and easily separable electrical interconnect structure. Connector 22 typically includes an insulating plastic housing, internal precision conductive terminals (springs, pins / holes), and possible locking mechanisms (such as snap-fit ​​613, springs) to ensure electrical conductivity stability and mechanical connection reliability when connector 22 mates with electrical connector 60.

[0045] Specifically, the ear hook 200 refers to the curved structural component in the earphone 1000 that directly contacts or hangs on the user's ear. In this application, the ear hook 200 conforms to the ergonomic curve shape of the ear, ensuring that the earphone 1000 is worn securely and comfortably, and preventing the earphone 1000 from accidentally falling off.

[0046] Specifically, the ear hook 200 has an electrical connector 60 inside. The electrical connector 60 is a plug-in terminal installed inside or at the end of the ear hook 200 and connected to other electrical components of the headphone 1000 (such as speakers, microphones, sensors, etc.) via wires (or flexible circuits). The physical shape and size of one end of the electrical connector 60 correspond to the connector 22 in the battery assembly 100, and the two can be precisely matched to achieve a plug-in connection.

[0047] It is understood that this application provides a battery assembly 100, which includes a battery casing 10 and a circuit board assembly 20. The circuit board assembly 20 is at least partially housed within the battery casing 10, and the battery casing 10 can protect the circuit board assembly 20. The circuit board assembly 20 includes a first circuit board 21 and a connector 22. The connector 22 is disposed on one side of the first circuit board 21 and is electrically connected to the first circuit board 21. The connector 22 is configured to insert into an electrical connector 60 inside the ear hook 200, thereby electrically connecting the connector 22 to the electrical connector 60, and thus achieving an electrical connection between the first circuit board 21 and the electrical connector 60. This application replaces the prior art method of soldering the electrical connector 60 (e.g., wires) to the first circuit board 21 by providing a connector 22 on the first circuit board 21, thereby establishing an electrical connection between the electrical connector 60 and the first circuit board 21. The plug-in relationship between the electrical connector 60 and the connector 22 provides cushioning when the battery assembly 100 is subjected to external impact, making the electrical connection between the electrical connector 60 and the first circuit board 21 more stable. This ensures that the soldered wires are less likely to break when the earphone 1000 is dropped and subjected to external force, improving the earphone 1000's drop resistance and extending its service life. Furthermore, the plug-in relationship between the electrical connector 60 and the connector 22 makes it easier to remove the connector 22 from the electrical connector 60, facilitating the repair and replacement of parts in the battery assembly 100 and improving repair efficiency.

[0048] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the connector 22 has a receiving groove 221 on the side facing the ear hook 200, and the inner top wall of the receiving groove 221 has a first protrusion 2211. The first protrusion 2211 is configured to be electrically connected to the latch 613 on the plug portion 61 of the electrical connector 60; or, the connector 22 has a receiving groove 221 on the side facing the ear hook 200, the inner top wall of the receiving groove 221 has a latch 613, the top surface of the plug portion 61 of the electrical connector 60 has a first protrusion 2211, and the latch 613 is configured to be electrically connected to the first protrusion 2211.

[0049] Specifically, the receiving groove 221 refers to a recessed cavity structure with a specific geometry and size located on the side of the connector 22 facing the ear hook 200. The function of the receiving groove 221 is to provide precise guidance, limiting, and physical accommodation space for the insertion portion 61 of the electrical connector 60, ensuring reliable and controllable insertion process. The receiving groove 221 is set on a specific surface of the connector 22, which faces the insertion direction of the ear hook 200 after assembly, forming the first physical interface for the electrical connector 60 to enter. The receiving groove 221 can be U-shaped, rectangular, or irregularly shaped, and is slightly larger than the outer shape of the insertion portion 61, so that it forms a suitable clearance fit after being accommodated.

[0050] Specifically, the inner top wall of the receiving groove 221 is provided with a first protrusion 2211. The first protrusion 2211 refers to a conductive metal spring or insert structure that protrudes from the inner top wall of the receiving groove 221 into the groove. The purpose of the first protrusion 2211 is to establish an elastic electrical connection with the corresponding metal contact on the insertion part 61 when the electrical connector 60 is inserted into the groove. The first protrusion 2211 can be fixed at a predetermined position on the inner top wall of the receiving groove 221 (usually arranged in groups along the insertion direction) to ensure precise alignment with the contact below after the insertion part 61 is fully inserted. The first protrusion 2211 can be an integrally formed spring or a metal contact point independently welded to the groove wall. The surface of the first protrusion 2211 can be gold-plated or nickel-plated to improve corrosion resistance and conductivity.

[0051] Furthermore, the electrical connector 60 is also provided with a buckle 613. When the first protrusion 2211 is electrically connected to the plug portion 61 of the electrical connector 60, the buckle 613 can be used to clamp the first protrusion 2211, preventing the earphone 1000 from swinging during use and causing the first protrusion 2211 to be separated from the plug portion 61 of the electrical connector 60, thereby enhancing the firmness of the electrical connection between the first protrusion 2211 and the plug portion 61 of the electrical connector 60.

[0052] Furthermore, the buckle 613 can also be provided on the inner top wall of the receiving groove 221, and the top surface of the plug portion 61 of the electrical connector 60 can also be provided with a first protrusion 2211, that is, the position of the buckle 613 can be interchanged with the position of the first protrusion 2211, and the buckle 613 is configured to be electrically connected to the first protrusion 2211.

[0053] Please see Figure 2 , Figure 3 and Figure 4In some embodiments, the inner wall of the receiving groove 221 is provided with a second protrusion 2212, which is configured to cooperate with the limiting sub-part 614 of the plug-in part 61 to mechanically connect the connector 22 to the electrical connector 60; or, the inner wall of the receiving groove 221 is provided with a limiting sub-part 614, which is configured to cooperate with the second protrusion 2212 of the plug-in part 61 to mechanically connect the connector 22 to the electrical connector 60.

[0054] Specifically, the second protrusion 2212 refers to a rigid plastic or metal reinforced structure that protrudes into the groove from the left or right inner sidewalls (or one of the left or right inner sidewalls) of the receiving groove 221. The function of the second protrusion 2212 is as a key component of the mechanical locking mechanism. By forming a physical interference fit with the limiting sub-part 614 of the insertion part 61, it prevents the electrical connector 60 from disengaging from the connector 22 during vibration, tension, or accidental collision. The second protrusions 2212 are symmetrically distributed at predetermined points on both sides (or one side) of the inner wall of the receiving groove 221, usually in the middle to rear section in the insertion direction, ensuring that the locking effect is generated only after the insertion part 61 reaches the working position.

[0055] Specifically, the limiting sub-part 614 refers to a recessed groove, opening, or protruding step structure located on the side surface of the plug portion 61 of the electrical connector 60. The function of the limiting sub-part 614 is to establish a complementary physical engagement with the second protrusion 2212. The limiting sub-part 614 has a groove at a precise position corresponding to the space of the plug portion 61 sidewall and the second protrusion 2212. The geometry of the limiting sub-part 614 (such as a U-shaped groove or a rectangular hole) perfectly matches the outer contour of the second protrusion 2212.

[0056] Please see Figure 2 and Figure 3 In some embodiments, the battery assembly 100 further includes a bracket 30, which is housed within the battery casing 10, and the first circuit board 21 is plugged into the bracket 30.

[0057] Specifically, the bracket 30 is a rigid metal or high-strength engineering plastic structural component inside the battery assembly 100. The bracket 30 is completely housed within the battery casing 10. The core function of the bracket 30 is to provide three-dimensional positioning support and stress buffering for the first circuit board 21, achieving precise, stable, and maintainable physical fixation of the circuit board assembly 20 within the battery casing 10. The bracket 30 can be rigidly fixed to the inner cavity sidewall of the battery casing 10 by means of clips 613, screws, or solder joints, becoming the mounting reference plane for the circuit board assembly 20.

[0058] Furthermore, the inner sidewall of the receiving groove 221 may be provided with a limiting sub-part 614, which is configured to cooperate with the second protrusion 2212 of the plug-in part 61, that is, the position of the second protrusion 2212 can be interchanged with the position of the limiting sub-part 614 so that the connector 22 is mechanically connected to the electrical connector 60.

[0059] Please see Figure 2 and Figure 3 In some embodiments, the sidewall of the battery case 10 forms a receiving cavity 11, and the inner side of the sidewall of the battery case 10 is recessed outward to form a first mounting groove 12. The two sides of the bracket 30 are inserted into the first mounting groove 12, and at least a portion of the bracket 30 is received in the receiving cavity 11.

[0060] Specifically, the accommodating cavity 11 is a protective space formed by the upward extension of the side wall of the battery casing 10. The core function of the accommodating cavity 11 is to provide a safe operating space with fully enclosed physical containment and electromagnetic environment isolation for the internal components (support 30 and circuit board assembly 20). The inner side of the side wall of the battery casing 10 is recessed outward to form a first mounting groove 12. The first mounting groove 12 is a recessed groove in the thickness direction of the side wall of the battery casing 10. The first mounting groove 12 can achieve tool-free insertion of the components in the accommodating cavity 11 by symmetrically clamping the support 30 on both sides.

[0061] Please see Figure 2 and Figure 3 In some embodiments, the sidewall of the bracket 30 forms a receiving cavity 31, and the inner side of the sidewall of the bracket 30 is recessed outward to form a second mounting groove 32. The opposite sides of the first circuit board 21 are respectively inserted into the second mounting groove 32, and the first circuit board 21 is at least partially housed in the receiving cavity 31.

[0062] Specifically, the receiving cavity 31 is a semi-enclosed rectangular space structure enclosed by the side walls of the bracket 30. The function of the receiving cavity 31 is to provide a protective area for the first circuit board 21, which provides physical containment, freedom of movement constraint, and external stress isolation. The inner side of the side wall of the bracket 30 is recessed outward to form a second mounting groove 32. The second mounting groove 32 is a continuous linear recessed channel machined outward from the inner side of the side wall of the bracket 30. The function of the second mounting groove 32 is to precisely guide the first circuit board 21 into the bracket 30 along a predetermined path through symmetrical clamping on both sides, and to lock the first circuit board 21 onto the bracket 30, thereby achieving physical fixation of the first circuit board 21.

[0063] Please see Figure 2 and Figure 3In some embodiments, the battery assembly 100 further includes a power supply unit 40 housed within the battery casing 10 and a second circuit board 23 housed within the battery casing 10. The second circuit board 23 is electrically connected to the power supply unit 40. The first circuit board 21 and the second circuit board 23 are electrically connected through a conductive element. The second circuit board 23 is located between the first circuit board 21 and the power supply unit 40. The first mounting surface of the first circuit board 21 for mounting electronic devices (not shown in the figure) is perpendicular to the second mounting surface of the second circuit board 23 for mounting electronic devices (not shown in the figure).

[0064] Specifically, the power supply unit 40 is an energy storage medium (such as a battery cell) encapsulated within the battery assembly 100. The power supply unit 40 can convert chemical energy into controllable DC electrical energy and provide basic power input for the entire headphone 1000 system. The second circuit board 23 is a dedicated power conversion and distribution substrate located between the power supply unit 40 and the first circuit board 21. The second circuit board 23 can be used to realize efficient power transformation, path switching and load matching control, and conduct the electrical energy of the power supply unit 40 to the first circuit board 21, realizing the electrical connection between the first circuit board 21 and the power supply unit 40.

[0065] Specifically, the first mounting surface is a physical surface area on the first circuit board 21 of the battery assembly 100, specifically designed to support, fix, and electrically connect electronic components (such as resistors, capacitors, integrated circuits, connectors, etc.) to the circuit board. The first mounting surface is an integral part of the first circuit board 21. All electronic components that need to be mounted on the first circuit board 21 undergo physical mounting and electrical connection (usually through soldering or surface mounting) on ​​this first mounting surface.

[0066] Specifically, the second mounting surface is a physical surface area on the second circuit board 21 of the battery assembly 100, specifically designed to support, fix, and electrically connect electronic components (such as resistors, capacitors, integrated circuits, connectors, etc.) to the circuit board. The second mounting surface is an integral part of the second circuit board 21. All electronic components that need to be mounted on the second circuit board 21 undergo physical mounting and electrical connection (usually through soldering or surface mounting) on ​​this second mounting surface.

[0067] Furthermore, the first mounting surface of the first circuit board 21 and the second mounting surface of the second circuit board 23 are spatially perpendicular to each other. The first circuit board 21 and the second circuit board 23 are not placed parallel to each other, but rather arranged with one plane as a reference and the other plane forming a 90-degree angle (perpendicular to each other) with the reference plane. For example, the first circuit board 21 is placed horizontally, while the second circuit board 23 is mounted vertically on the edge of the first circuit board 21.

[0068] Please see Figure 2 and Figure 3 In some embodiments, conductive elements (for connection) Figure 3 The first circuit board 21 and the second circuit board 23 are at least one of wires, flexible circuit boards and conductive metal parts; and / or, at least one of the first circuit board 21 and the second circuit board 23 is a protection circuit board and is configured to provide overvoltage protection and / or overcurrent protection when an external power supply charges the power supply unit 40.

[0069] Specifically, this application uses a flexible material for the conductive component, such as at least one of wires, flexible circuit boards, and conductive metal components. This ensures that the connection between the first circuit board 21 and the second circuit board 23 is not easily damaged when the battery assembly 100 is subjected to external impact, thereby improving the impact resistance of the battery assembly 100 and extending its service life.

[0070] Specifically, at least one of the first circuit board 21 and the second circuit board 23 is a protection circuit board. When the user charges the power supply unit 40 using an external power source, the protection circuit board can provide overvoltage protection and / or overcurrent protection for the power supply unit 40, preventing damage to the power supply unit 40 due to fluctuations in the external power supply. The first circuit board 21 and the second circuit board 23 may also not be protection circuit boards, but other types of circuit boards.

[0071] Please see Figure 1 , Figure 2 and Figure 3 The present application also provides an earphone 1000, which includes an ear hook 200 and a battery assembly 100 as described in any of the above embodiments. The ear hook 200 includes an electrical connector 60, which is electrically connected to a first circuit board 21.

[0072] It is understood that this application provides an earphone 1000, which includes an ear hook 200 and a battery assembly 100 as described in any of the above embodiments. The ear hook 200 includes an electrical connector 60, which is electrically connected to a first circuit board 21. The battery assembly 100 includes a battery housing 10 and a circuit board assembly 20, with the circuit board assembly 20 at least partially housed within the battery housing 10, which provides protection for the circuit board assembly 20. The circuit board assembly 20 includes a first circuit board 21 and a connector 22, which is disposed on one side of the first circuit board 21 and electrically connected to it. The connector 22 is configured to insert into the electrical connector 60 inside the ear hook 200, thereby electrically connecting the connector 22 to the electrical connector 60, and thus achieving an electrical connection between the first circuit board 21 and the electrical connector 60. This application provides a connector 22 on the first circuit board 21, which establishes an electrical connection between the electrical connector 60 and the first circuit board 21. This replaces the prior art method of soldering the electrical connector 60 (e.g., wires) to the first circuit board 21. The insertion relationship between the electrical connector 60 and the connector 22 creates a more stable electrical connection between the electrical connector 60 and the first circuit board 21, ensuring that the soldered wires are less likely to break when the earphone 1000 is dropped and subjected to external force, thus improving the drop resistance of the earphone 1000 and extending its service life.

[0073] Please see Figure 1 , Figure 2 and Figure 4 In some embodiments, the earphone 1000 further includes a transducer assembly 300, and the ear hook 200 includes an ear hook body 50, one end of which is connected to the battery housing 10, and the other end is connected to the transducer assembly 300; the electrical connector 60 includes a plug portion 61 and a connecting portion 62, the plug portion 61 including a first sub-part 611 and a second sub-part 612 connected to each other, the first sub-part 611 being housed inside the connector 22, and the second sub-part 612 being located outside the connector 22. The connecting portion 62 passes through the ear hook body 50, one end of which is connected to the second sub-part 612, and the other end is connected to the transducer assembly 300.

[0074] Specifically, the ear hook body 50 can be an ergonomically curved beam frame injection molded from flexible material or titanium-nickel alloy. The ear hook body 50 constitutes the core load-bearing skeleton of the ear hook 200. The front end of the ear hook body 50 is rigidly connected to the battery shell 10, and the rear end of the ear hook body 50 is equipped with a transducer component 300, thereby achieving three-point stable suspension of the earphone 1000 on the auricle.

[0075] Specifically, the plug-in portion 61 is a modular interface in the electrical connector 60 used to establish electrical and mechanical interlocking with the connector 22. The plug-in portion 61 is composed of a first sub-part 611 and a second sub-part 612 nested coaxially. The plug-in portion 61 is used for signal transmission, contact impedance suppression, and insertion / removal guidance. The first sub-part 611 is located at the front end of the plug-in portion 61. The first sub-part 611 has conductive pins that directly contact the first protrusion 2211 inside the connector 22, and also has a latch 613 for firmly fixing the first protrusion 2211. The second sub-part 612 is adjacent to the first sub-part 611 and can be used to provide force for the user's fingers to assist the user in pulling out or inserting the plug-in portion 61 into the connector 22.

[0076] Specifically, the connecting part 62 can be a multi-core composite wire harness that passes through the ear hook body 50 to transmit electrical energy to the transducer assembly 300. The transducer assembly 300 is a component used to convert electrical signals into sound energy.

[0077] Please see Figure 4 In some embodiments, the second sub-part 612 is provided with a gripping sub-part 6121, which is configured for a user to grip.

[0078] Specifically, the gripping sub-part 6121 is an ergonomic gripping enhancement structure located on the outer surface of the second sub-part 612 of the insertion part 61. The gripping sub-part 6121 may have grooves or protrusions to optimize the contact interface between the user's fingers and the second sub-part 612 through specific geometric shapes and surface treatment technologies, so that the user can obtain a precise force fulcrum and tactile feedback during insertion and removal operations.

[0079] In summary, this application provides an earphone 1000, which includes an ear hook 200 and a battery assembly 100 as described in any of the above embodiments. The ear hook 200 includes an electrical connector 60, which is electrically connected to a first circuit board 21. The battery assembly 100 includes a battery housing 10 and a circuit board assembly 20, with the circuit board assembly 20 at least partially housed within the battery housing 10, which provides protection for the circuit board assembly 20. The circuit board assembly 20 includes a first circuit board 21 and a connector 22, which is disposed on one side of the first circuit board 21 and electrically connected to it. The connector 22 is configured to insert into the electrical connector 60 inside the ear hook 200, thereby electrically connecting the connector 22 to the electrical connector 60, and thus achieving an electrical connection between the first circuit board 21 and the electrical connector 60. This application provides a connector 22 on the first circuit board 21, which establishes an electrical connection between the electrical connector 60 and the first circuit board 21. This replaces the prior art method of soldering the electrical connector 60 (e.g., wires) to the first circuit board 21. The insertion relationship between the electrical connector 60 and the connector 22 creates a more stable electrical connection between the electrical connector 60 and the first circuit board 21, ensuring that the soldered wires are less likely to break when the earphone 1000 is dropped and subjected to external force, thus improving the drop resistance of the earphone 1000 and extending its service life.
