[0037] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0038] like Figure 1 and Figure 2 As shown, the present invention provides a Bluetooth headset that can switch between in-ear and open-ear styles. It includes a sound-emitting member 10, an ear hook 20, and an ear cap 30. The sound-emitting member 10 is provided with a sound-emitting hole 11. The ear hook 20 is connected to the sound-emitting member 10. When worn, the ear hook 20 is configured to bypass the auricle from the user's cavum concha so that the sound-emitting hole 11 is positioned toward the user's ear canal. The ear cap 30 is detachably connected to the sound-emitting member 10 and is used to transmit sound through the sound-emitting hole 11 to the ear canal. When the ear cap 30 is connected to the sound-emitting member 10 and worn, the ear cap 30 is configured to cooperate with the user's ear canal. When the ear cap 30 is detached from the sound-emitting member 10 and worn, the sound-emitting hole 11 is spaced apart from the user's ear canal. This headphone design allows users to switch between in-ear and open-ear listening experiences based on different usage scenarios and personal preferences. This flexibility makes the headphones adaptable to a wider range of usage environments, such as sports, office work, or daily commuting. By switching the ear caps 30, users can choose between in-ear mode for better sound isolation and open-ear mode for natural sound, meeting audio needs in different situations, whether enjoying an immersive music experience or communicating with others in an open environment. Furthermore, since the ear caps 30 are detachable, it is not only convenient for users to clean them, but also easy to replace worn or dirty ear caps 30, extending the overall life of the headphones.

[0039] like Figure 1 and Figure 2 As shown, a battery compartment 40 is provided at the end of the ear hook 20 away from the sound-emitting component 10. Providing the battery compartment 40 at the distal end of the ear hook 20 can balance the weight distribution of the earphones, avoid most of the weight being concentrated near the ear canal, thereby reducing the pressure in the ear canal and improving the comfort of long-term wearing. The battery compartment 40 being located at the distal end of the ear hook 20 helps to enhance the wearing stability of the earphones. Due to the weight of the battery compartment 40, the ear hook 20 can better fit the user's auricle, reducing the shaking or falling off of the earphones during exercise. Providing the battery compartment 40 at the end of the ear hook 20 away from the sound-emitting component 10 not only helps to balance the weight of the earphones and improve the wearing comfort and stability, but also makes rational use of space and improves the aesthetics and practicality of the product.

[0040] In some embodiments, the ear cap 30 includes a detachable portion 31 that detachably connects to the sound-emitting element 10 and a fitting portion 32 for fitting into the user's ear canal. The detachable portion 31 is harder than the fitting portion 32. The higher hardness of the detachable portion 31 means it is more wear-resistant and can withstand frequent plugging and unplugging without damage. This not only increases the lifespan of the ear cap 30 but also ensures a secure connection each time, reducing inconvenience caused by unstable connections. The fitting portion 32 is made of a softer material to better conform to the shape of the user's ear canal, reducing discomfort during prolonged wear. The soft material also helps isolate external noise, enhancing the audio quality. Combining materials of varying hardness optimizes acoustic properties. The hard detachable portion 31 effectively reduces resonance and distortion during sound transmission, while the soft fitting portion 32 helps create a good seal, improving low-frequency response and enhancing overall sound quality. Specifically, the fitting portion 32 and detachable portion 31 are integrally molded using a two-shot injection molding process of soft and hard plastic. The one-piece design makes the ear cap 30 a solid whole, avoiding the problem of loosening or falling off between multiple components, and improving the structural strength of the product and the stability of long-term use. Through the two-color injection molding process, the manufacture of the ear cap 30 can be completed in one go, without the need for subsequent assembly steps, which simplifies the production process, reduces manufacturing costs, and reduces quality problems caused by improper assembly. One-piece molding reduces the connection points between components, thereby reducing possible failure points, making the ear cap 30 more durable and less likely to be damaged by friction or collisions during daily use. The different properties of soft and hard rubber materials can take into account both comfort and functionality. The hard rubber part ensures a good connection with the main body of the earphone, while the soft rubber part provides a comfortable wearing experience and can better adapt to the shape of the ear canal of different users, improving the fit and sealing when worn.

[0041] In this embodiment, the earphones include at least two ear caps 30, and the diameters and / or lengths of the wearing portions 32 of the at least two ear caps 30 are different. Specifically, since different users have different ears, in order to better adapt to the ear canal shapes of different users and improve the fit and sealing when worn, this embodiment provides multiple models of ear caps 30. For example, they can be divided according to the diameter of the wearing portion 32, and three different sizes of ear caps 30 are provided: small, medium, and large. The inner diameter of the wearing portion 32 is 6mm to 10mm, and the outer diameter is 10mm to 20mm. Alternatively, they can be divided according to the length of the wearing portion 32 into single-leaf, double-leaf, and three-leaf ear caps. The double-leaf ear cap in this embodiment is formed by the superposition of two wearing portions 32, and the three-leaf ear cap is formed by the superposition of three wearing portions 32. Users can choose the appropriate ear cap 30 according to their preferences or ear size to improve wearing comfort, and it is also convenient for users to replace the ear caps 30 according to different usage scenarios.

[0042] like Figure 3In one embodiment, the sound-emitting component 10 is provided with a first plug-in slot 12 around the sound-emitting hole 11, and the ear cap 30 includes a first plug-in portion 33 that plugs into and cooperates with the first plug-in slot 12; the sound-emitting component 10 is provided with a second plug-in portion, and the ear cap 30 includes a second plug-in slot that plugs into and cooperates with the second plug-in portion. Specifically, an annular groove is provided around the sound-emitting hole 11 to form the first plug-in slot 12, and the first plug-in portion 33 is a hard rubber ring that matches the first plug-in slot 12. The matching design of the first plug-in portion 33 and the first plug-in slot 12 can ensure a firm connection between the ear cap 30 and the sound-emitting component 10, prevent the ear cap 30 from accidentally falling off during exercise or other activities, and enhance the overall stability of the earphones. The plug-in structure reduces the wear caused by traditional screws or other fixing methods, reduces the risk of damage caused by repeated disassembly and assembly, and thus extends the service life of the earphones and their accessories. The plug-in design makes the ear caps 30 easy to remove for cleaning or replacement, especially for users who frequently sweat or use in humid environments. This design helps keep the ear caps 30 hygienic. Furthermore, if the manufacturer offers multiple sizes or types of ear caps 30, users can choose the appropriate ear cap 30 based on their preferences or ear size, improving wearing comfort and making it easier for users to replace the ear caps 30 according to different usage scenarios.

[0043] More preferably, the first plug-in portion 33 and the first plug-in slot 12 are configured to form an interference fit. An interference fit means that the plug-in portion is slightly larger than the plug-in slot. This design ensures a very tight connection between the ear cap 30 and the sound-emitting component 10, effectively preventing the ear cap 30 from loosening or falling off during use, and improving the reliability of the connection. The interference fit can improve the seal between the ear cap 30 and the sound-emitting hole 11, particularly in in-ear mode. This design helps block external noise and enhances the audio experience, especially in situations where high sound insulation is required.

[0044] like Figure 4As shown, in one embodiment, the sound-emitting component 10 is provided with a snap-fitting protrusion 13 located around the sound-emitting hole 11, and the ear cap 30 includes a snap-fitting groove 34 that snaps into engagement with the snap-fitting protrusion 13. Specifically, the sound-emitting hole 11 is protruded outwardly around a snap-fitting protrusion 13 with an L-shaped cross-section, and the ear cap 30 is provided with a snap-fitting groove 34 that matches the L-shaped protrusion 13. Through the elastic deformation of the ear cap 30, the ear cap 30 can be fixed to the sound-emitting component 10. The snap-fitting structure allows the user to quickly install the ear cap 30 on the sound-emitting component 10 or easily remove it without the need for additional tools, greatly improving the convenience of use. The snap-fitting design ensures that the ear cap 30 can be accurately aligned with the position of the sound-emitting hole 11 each time it is installed, avoiding sound transmission problems caused by position offset and ensuring the consistency of audio quality. In other embodiments, the snap-fitting protrusion 13 and the snap-fitting groove 34 can be other forms of snap-fit ​​structures, which are not described here.

[0045] In other embodiments, the sound-emitting element 10 is provided with a first magnetic portion, and the ear cap 30 is provided with a second magnetic portion that magnetically cooperates with the first magnetic portion. This magnetic design allows the ear cap 30 to be quickly attached to the sound-emitting element 10 and easily detached when needed, greatly simplifying the user's operation and enhancing convenience. The magnetic force helps the ear cap 30 automatically align with the sound-emitting hole 11, ensuring that the ear cap 30 is accurately aligned with the sound-emitting hole 11 every time it is installed, improving installation accuracy and ensuring the quality of sound transmission. The design of the magnetic portion allows the user to easily switch between in-ear and open-ear modes by simply attaching or detaching the ear cap 30 without complicated operations. Specifically, the first and second magnetic portions are arranged with opposite magnetic poles. Due to the opposite magnetic poles, the ear cap 30 is naturally attracted and aligned with the sound-emitting element 10, ensuring that the ear cap 30 is accurately installed around the sound-emitting hole 11 without manual adjustment. This also ensures that the sound transmission hole of the ear cap 30 is aligned with the user's ear canal, preventing sound leakage during use.

[0046] like Figures 5 to 7 As shown, in one embodiment, the ear cap 30 includes a sleeve portion 35 that is detachably connected to the sound-emitting member 10 and a wearing portion 32 for fitting into the user's ear canal. The sleeve portion 35 is sleeved onto the outside of the sound-emitting member 10. Specifically, the sleeve portion 35 is capable of elastic deformation. The design of the sleeve portion 35 enables the ear cap 30 to be securely wrapped around the outside of the sound-emitting member 10. The tight fit ensures that the ear cap 30 will not easily come loose, thereby improving wearing stability.

[0047] Preferably, the outer surface of the sound-emitting member 10 is provided in a socket groove 14 for cooperating with the socket portion 35, so that the outer surface of the socket portion 35 is flush with the outer surface of the sound-emitting member. The design of the socket portion 35 being flush with the outer surface of the sound-emitting member 10 makes the overall appearance of the earphone more concise and smooth, without protruding parts, thereby improving the aesthetics of the product. The flush design reduces the abruptness of the edge of the ear cap 30, making the earphone more comfortable when worn, reducing pressure and discomfort on the auricle, and is especially suitable for long-term wear. The close fit between the socket portion 35 and the socket groove 14 helps to form a better sealing effect, especially in the in-ear mode, which can effectively isolate external noise and enhance the audio experience.

[0048] In this embodiment, as shown in the figure, the area covered by the sleeve portion 35 on the sounding member occupies at least one-third of the outer surface of the sounding member. A larger coverage area means a larger contact surface between the sleeve portion 35 and the sounding member 10, which can provide a stronger fixing force, ensuring that the ear cap 30 is more stable during wearing and not easy to fall off. Specifically, the area covered by the sleeve portion 35 on the sounding member occupies one-half of the outer surface of the sounding member (e.g., Figure 5 As shown), two-thirds (as shown Figure 6 as shown) or all (as shown Figure 7 The design of the sleeve portion 35 covering a larger area of ​​the sound-emitting member 10 helps optimize the sound wave propagation path, reduce sound leakage, and improve the overall sound quality performance.

[0049] In summary, this embodiment provides a Bluetooth headset that can switch between in-ear and open-ear styles. Since the ear cap 30 is detachable, it not only facilitates cleaning of the ear cap 30 but also facilitates replacement of worn or dirty ear caps 30. By switching the ear cap 30, the user can choose between an in-ear mode with better sound insulation and an open-ear mode with natural sound effects, meeting audio needs in different scenarios, whether enjoying an immersive music experience or communicating with others in an open environment. All technical features of this embodiment can be freely combined according to actual needs.

[0050] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
