Choosing the right headphones for different occasions has become a symbol of trendy lifestyle. The outer surface of metal ear shells may have some sharp edges, some small. Since the metal ear shells are in close contact with the face and ear skin, these sharp edges can pose a certain risk to the user.

[0032] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4To address the aforementioned issues, this application provides a wireless earphone 10, comprising a metal housing 20, a fabric cover 30, a charging assembly, and an insulating component 50. The metal housing 20 has a sound outlet hole 21 on the sound outlet side. The fabric cover 30 is detachably fixed to the surface of the metal housing 20 and located on the side where the sound outlet hole 21 is located. The metal housing 20 also has a first through hole 22. The charging assembly includes a circuit board and a conductive post 41. The circuit board is disposed inside the metal housing 20. The conductive post 41 is electrically connected to the circuit board and passes through the first through hole 22 to be exposed on the outside of the metal housing 20. The insulating component 50 is disposed between the conductive post 41 and the wall of the first through hole 22.

[0033] In this wireless earphone 10, the wireless earphone 10 includes a metal shell 20, a fabric cover 30, a charging component, and an insulating component 50. The metal shell 20 houses the internal components of the earphone and isolates them from the external environment. The metal shell 20 can be made of aluminum alloy, copper, stainless steel, or other metal materials. Metal shells made of these materials offer good mechanical properties and sound quality. They also possess advantages such as high rigidity, high precision, and corrosion resistance. High rigidity and impact resistance reduce sound resonance and maintain sound resolution and clarity, thus enhancing the user experience when using the wireless earphone 10.

[0034] refer to Figure 1 , Figure 3 , Figure 5 and Figure 8In some embodiments, the wireless earphone 10 includes a charging component and an insulating component 50. The metal housing 20 has a first through-hole 22. The charging component includes a circuit board and conductive posts 41. The circuit board is located inside the metal housing 20. The conductive posts 41 are electrically connected to the circuit board and pass through the first through-hole 22 to be exposed on the outside of the metal housing 20. The insulating component 50 is located between the conductive posts 41 and the wall of the first through-hole 22. Direct contact between the conductive posts and the metal housing 20 poses a risk; therefore, an insulating component 50 is provided on the outside of the conductive posts 41 to enclose them and avoid this risk. In some embodiments, the insulating component 50 and the conductive posts 41 can be designed as a single piece. Specifically, the insulating component 50 encloses the conductive posts 41, and the charging component is integrally formed by injection molding, achieving insulation between the charging component and the metal housing 20. Making the insulating component 50 and the conductive posts 41 into a single structure eliminates gaps between them, which is beneficial for the dust and water resistance of the wireless earphone 10 and increases its service life. In some embodiments, the insulating member 50 is sleeved on the outer surface of the conductive post 41, and the side of the insulating member 50 near the inner wall of the metal housing 20 is in close contact with the metal housing 20. The gap between the two is small, which can be set to 0.025 mm, allowing the components inside the metal housing 20 to be installed more easily. In some embodiments, the wall of the first through hole 22 forms a stepped surface 221, and the insulating member 50 is fixed to the stepped surface 221 with adhesive. Yellow glue can be applied to the stepped surface 221 to seal the gap, so that the internal structure of the metal housing 20 of the wireless earphone 10 is compact and stable. The conductive post 41 is a conductive component used to connect the wireless earphone 10 and the charging case. The conductive post 41 is typically located on the stem of the wireless earphone 10. When the wireless earphone 10 is placed in the charging case for charging, the conductive post 41 connects with the contact points inside the charging case to achieve power transmission. The conductive post 41 can be a precision connector, a spring-loaded pin design, providing stable connection and power disconnection when the wireless earphone 10 is inserted or removed. It is usually made of copper. In some embodiments, the copper conductive post 41 can be gold-plated to improve its conductivity and corrosion resistance. The circuit board of the wireless earphone 10 is housed within the metal casing 20. The circuit board is a precision electronic device capable of wireless communication and audio processing. Various electronic components, such as integrated circuits, resistors, and capacitors, can be mounted on the circuit board and interconnected through vias or pads to form a circuit system. In some implementations, the circuit board can be divided into a main control board and a speaker board. The main control board is responsible for receiving and sending wireless signals, processing audio data, and controlling the battery and charging status, etc.; the speaker board is responsible for converting audio signals into sound output, collecting sound input, reducing noise interference, and other functions.In some embodiments, the wireless earphone 10 further includes an ear hook 70, one end of which is connected to the metal housing 20. The ear hook 70 can be used to contact the user's skin. Specifically, the ear hook 70 can be a curved hanging arm or a clamping element. In one embodiment, the ear hook 70 extends in a curved manner around the metal housing 20, providing support. When the user uses the wireless earphone 10, the ear hook 70 can be placed on the user's auricle, securing the earphone to the user's ear. In some embodiments, the ear hook 70 can be shaped like an auricle, typically being arc-shaped. In some embodiments, the ear hook 70 can also be customized according to the user's needs to improve the user's comfort when wearing the wireless earphone 10. When the user wears the wireless earphone 10, with the ear hook 70 placed on their auricle, the sound outlet 21 of the wireless earphone 10 is placed in the user's ear canal.

[0035] refer to Figures 3-8 In some embodiments, the cover 30 has a second through hole 31 that communicates with the first through hole 22, preventing the conductive post 41 from being blocked by the cover 30 and affecting the functionality of the wireless earphone 10. The conductive post 41 passes through the second through hole 31 and is exposed on the outside of the cover 30, which increases the user's comfort when wearing the wireless earphone 10 while ensuring its normal use. In some embodiments, an insulating member 50 is disposed between the conductive post 41 and the hole wall of the second through hole 31. The insulating member 50 wraps around the conductive post 41, providing insulation between the conductive post 41 and the metal housing 20. In some embodiments, the insulating member 50 can be made of plastic material, such as PC (polycarbonate), ABS (acrylonitrile, butadiene, styrene terpolymer), and PC / ABS alloy (engineering plastic alloy).

[0036] refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 10In some embodiments, the covering 30 includes a decorative panel 32 and a covering layer 33.

When the covering 30 is disposed on the metal housing 20, the metal housing 20 of the wireless earphone 10 has the decorative panel 32 and the covering layer 33 arranged sequentially. In some embodiments, the decorative panel 32 avoids the sound outlet 21 to prevent the decorative panel 32 from blocking the sound outlet 21, which helps ensure the normal use of the wireless earphone 10. In some embodiments, the decorative panel 32 is detachably fixed to the metal housing 20, which facilitates the replacement of the decorative panel 32 and the cleaning and maintenance of the wireless earphone 10. The covering layer 33 is fixed to the side of the decorative panel 32 away from the metal housing 20 and covers the decorative panel 32. Specifically, the decorative panel 32 may have a pattern, and the user can replace the decorative panel 32 with a different pattern according to their preference. In some embodiments, the covering layer 33 may be made of breathable fabric with a thickness of 0.2 to 0.3 mm. In some embodiments, patterns can be provided on the cover layer 33. Users can design the appearance of the wireless earphone 10 according to their preferences by replacing the decorative panel 32 or the cover layer 33. They can also combine the patterns of the decorative panel 32 and the cover layer 33 to achieve more patterns, colors, and styles, thus overcoming the monotony of the existing wireless earphone 10's appearance and increasing the user's enjoyment when using it. In some embodiments, the wireless earphone 10 can be designed as a uniquely shaped earphone, allowing for customization to fit the user's ears, increasing the visual richness of the wireless earphone 10 while improving wearing comfort.

[0037] refer to Figures 7-10 In some embodiments, the decorative panel 32 is provided with a first buckle 61, and the metal housing 20 is provided with a first slot 62. The first buckle 61 is fastened into the first slot 62. By fastening the first buckle 61 into the first slot 62, the decorative panel 32 can be fixed to the metal housing 20. The position of the first buckle 61 on the decorative panel 32 corresponds to the position of the first slot 62 on the metal housing 20. In other embodiments, the metal housing 20 is provided with a first buckle 61, and the decorative panel 32 is provided with a first slot 62. The first buckle 61 is fastened into the first slot 62. By fastening the first buckle 61 into the first slot 62, the decorative panel 32 can be fixed to the metal housing 20. The position of the first buckle 61 on the metal housing 20 corresponds to the position of the first slot 62 on the decorative panel 32.

[0038] In some embodiments, the decorative panel 32 has an arc-shaped protrusion, and the metal housing 20 has an arc-shaped groove. The arc-shaped protrusion can be engaged in the arc-shaped groove, thereby fixing the decorative panel 32 to the metal housing 20. The position of the arc-shaped protrusion on the decorative panel 32 corresponds to the position of the arc-shaped groove on the metal housing 20. In other embodiments, one of the metal housings 20 has an arc-shaped protrusion, and the decorative panel 32 has an arc-shaped groove. The arc-shaped protrusion can be engaged in the arc-shaped groove, thereby fixing the decorative panel 32 to the metal housing 20. The position of the arc-shaped protrusion on the metal housing 20 corresponds to the position of the arc-shaped groove on the decorative panel 32. Specifically, the decorative panel 32 has a pry bar 321 on the edge of the side with the arc-shaped protrusion or arc-shaped groove. The pry bar 321 is exposed on the outer surface of the wireless earphone 10. The user can pry the pry bar 321 to separate the decorative panel 32 from the metal housing 20, thus achieving the disassembly process of the decorative panel 32. In some embodiments, the fabric layer 33 is adhered to the decorative panel 32. Specifically, adhesive can be evenly sprayed onto the surface of the fabric layer 33 near the decorative panel 32, and then the adhesive-coated fabric layer 33 is adhered to the surface of the decorative panel 32 away from the metal housing 20. In some embodiments, a button 80 is provided on one side of the metal housing 20, and the button 80 is electrically connected to the circuit board. The side of the metal housing 20 may have a button 80 hole, which may be surrounded by an annular flange. The button 80 may be configured to receive the pressing pressure applied by the user and trigger a switch through the button 80 hole. In one embodiment, the metal housing 20 forms a keyway 81 corresponding to the position of the button 80. A rubber pad is provided in the keyway 81 to abut against the button 80, sealing the keyway 81. Accordingly, the rubber pad includes a soft rubber pad and a hard rubber pad. The soft rubber pad is disposed within the keyway 81 and covers the keyway 81. In some embodiments, the keyway 81 is located on the side of the metal housing 20 facing the ear hook 70. When the user wears the headphones through the ear hook 70, one side of the keyway 81 faces inward, improving the aesthetics of the wireless headphones 10. At this time, the user presses the hard rubber pad, causing the soft rubber pad to deform, thereby acting on the circuit board. Specifically, the soft rubber pad may include an integrally connected central protrusion and an edge connecting portion. The soft rubber pad and the hard rubber pad are bonded together with adhesive, for example, by injecting adhesive into the keyway 81, injecting adhesive into the upper surface of the soft rubber pad, or injecting adhesive into the mating gap between the hard rubber pad and the soft rubber pad. In some embodiments, the bottom edge of the soft rubber pad is formed with a plurality of protrusions that mate with the keyway 81. When the soft rubber pad is sealed and fixed in the keyway 81 by one-piece injection molding, the soft rubber pad and the metal shell 20 can be more tightly bonded through the cooperation between the keyway 81 and the protrusion, which ensures the sealing effect of the wireless earphone 10 and thus improves the waterproof effect of the wireless earphone 10.
