Implementation

[0016] Figure 1 is a perspective view of a wireless earphone according to an embodiment of the present invention. Figure 2 is a disassembly diagram of the wireless earphone of Figure 1. Figure 3 is a disassembly diagram of the wireless earphone of Figure 2 from another perspective. It should be noted that Figures 2 and 3 only use dashed lines to show the parts of the earphone body that need to be explained, omitting components such as speakers, in order to facilitate explanation.

[0017] Please refer to Figures 1 to 3. The wireless earphone 100 in this embodiment can be a true wireless stereo (TWS) earphone. Specifically, two wireless earphones 100 can be used as the left and right earphones, respectively, to wirelessly connect with electronic devices (such as smartphones or tablets), but the present invention is not limited thereto.

[0018] In this embodiment, the wireless earphone 100 includes an earphone body 110 and a battery assembly 120. The battery assembly 120 is detachably connected to the earphone body 110. Specifically, the earphone body 110 includes a housing 112, a conductive portion C1, and a first connector 111. The housing 112 has an opening A1. The conductive portion C1 is located inside the housing 112 and includes a first terminal and a second terminal for connecting to positive and negative terminals, respectively. The first connector 111 is connected to the housing 112. The battery assembly 120 includes a second connector 122 and a driving portion 124.

[0019] In this embodiment, the outer shell 112 includes an inner surface S1, and a first engaging member 111 is disposed on the inner surface S1 of the outer shell 112 and surrounds the opening A1. Here, the first engaging member 111 is a protrusion and has a first locking point 1111, but is not limited thereto.

[0020] In this embodiment, the second engagement member 122 is disposed on an outer surface S2 of the battery assembly 120. Here, the second engagement member 122 is a groove, but is not limited thereto. For example, the second engagement member 122 has an inlet B1 opposite to the drive unit 124, and includes a blocking wall W1 and a second locking point W11 located on the blocking wall W1.

[0021] In other embodiments, the first connecting member may be a groove and the second connecting member may be a protrusion; the present invention is not limited thereto. In other embodiments, the earphone body and the battery assembly may also be connected by snaps or threads for rotational disassembly and assembly; the present invention is not limited thereto.

[0022] In this embodiment, the second engaging member 122 is an L-shaped groove. When the first engaging member 111 enters the second engaging member 122 through the inlet B1, the first engaging member 111 is located in the first section 1221 of the second engaging member 122. By rotating the battery assembly 120 relative to the earphone body 110, the first engaging member 111 can be located in the second section 1222 of the second engaging member 122 to achieve a locking effect. In this embodiment, the first section 1221 is parallel to the opening direction N1, and the second section 1222 and the blocking wall W1 are not parallel to the opening direction N1, but the present invention is not limited thereto.

[0023] In this embodiment, in addition to restricting the movement of the first connecting member 111 in the opening direction N1 by the blocking wall W1, the first locking point 1111 and the second locking point W11 can also engage with each other to enhance the fixing effect. In this embodiment, the first locking point 1111 is a concave point and the second locking point W11 is a convex point, but the present invention is not limited thereto.

[0024] In this embodiment, the driving part 124 of the battery assembly 120 is annular and has a concave-convex appearance to increase friction and facilitate user finger operation, but is not limited thereto.

[0025] In one embodiment, when the wireless earphone 100 is impacted, the battery unit 121 will not easily fall out because the battery assembly 120 and the earphone body 110 have a good stable relationship.

[0026] With the above configuration, the user can lock or unlock the engagement between the first connector 111 and the second connector 122 by rotating the drive unit 124 in a rotation direction R1. In this way, the user can achieve the opening and closing function without tools, simply by rotating the battery assembly 120 relative to the earphone body 110, which is convenient for operation and battery assembly 120 replacement.

[0027] In detail, referring to Figure 2, in this embodiment, the battery assembly 120 includes a battery cell 121 and a sidewall 123 surrounding the battery cell 121. The battery cell 121 is fixed inside the sidewall 123, a second coupling member 122 is disposed on the outer surface S2 of the sidewall 123, and a driving part 124 is connected to the sidewall 123. The battery cell 121 has a first electrode E1 and a second electrode E2 facing the same side. That is, the first electrode E1 and the second electrode E2 are located on the same surface. In this embodiment, the second electrode E2 surrounds the periphery of the first electrode E1. The first electrode E1 is, for example, a positive electrode, and the second electrode E2 is, for example, a negative electrode; however, this invention is not limited thereto.

[0028] The advantage of this design is that the positive and negative contact positions of the battery unit 121 are in a ring shape rather than a single point. No matter how the user rotates the battery assembly 120 to any angle, the conductive part C1 of the earphone body 110 can make corresponding contact with the first electrode E1 and the second electrode E2 to conduct the battery unit 121.

[0029] Here, the conductive part C1 is a spring connector (POGO PIN), which can extend and float along the opening direction N1 and both ends can be used as contacts, but the present invention is not limited thereto.

[0030] Figures 4A and 4B are perspective views illustrating the operation of the battery assembly of the wireless earphone in Figure 1. Figure 5 is a side view of the wireless earphone in Figure 1. It should be noted that the earphone body in Figures 4A and 4B is depicted with dashed lines to show its outer contour and the first connecting member, in order to clearly show its connection to the second connecting member of the battery assembly. Other internal components of the earphone body are omitted for clarity.

[0031] Please refer to Figures 3 and 4B. In the first state shown in Figure 4B, the battery assembly 120 is assembled on the earphone body 110 and corresponds to the opening A1. The first connector 111 is fixed to the second connector 122, the first locking point 1111 is fixed to the second locking point W11, and the conductive part C1 (Figure 3) is electrically connected to the battery assembly 120.

[0032] During the transition from the first state shown in Figure 4B to the second state shown in Figure 3, an external force drives the first connector 111 to separate from the second connector 122, thereby causing the battery assembly 120 to separate from the earphone body 110.

[0033] In this embodiment, in the first state shown in FIG4B, a portion of the battery assembly 120 is located inside the opening A1, and another portion of the battery assembly 120 is located outside the opening A1, to facilitate user operation and replacement of the battery assembly 120. In other words, in the first state shown in FIG4B, the sidewall 123 of the battery assembly 120 is covered by the housing 112, and the drive portion 124 of the battery assembly 120 is located outside the opening A1. Furthermore, referring to FIG5, the drive portion 124 has a length L1 in the opening direction N1, and the length L1 is greater than or equal to 2 mm to facilitate user finger operation, but is not limited thereto.

[0034] Specifically, referring to Figures 3 and 4A, during assembly, the user inserts the battery assembly 120 into the opening A1 of the earphone body 110, allowing the first connector 111 to enter the first section 1221 of the second connector 122 through the inlet B1. Then, the second connector 122 is rotated in the rotation direction R1 (e.g., clockwise) so that the first connector 111 enters the second section 1222 of the second connector 122. The first locking point 1111 and the second locking point W11 engage with each other, completing the fixation and electrical connection, as shown in Figure 4B.

[0035] Conversely, during the disassembly of the battery assembly 120, the user only needs to rotate the second connector 122 in the rotation direction R1 (e.g., counterclockwise) to disengage the first locking point 1111 from the second locking point W11, and the first connector 111 moves from the second segment 1222 to the first segment 1221. Next, the user pulls the battery assembly 120 out in a direction away from the earphone body 110 to complete the disassembly. At this point, the user can insert another fully charged battery assembly into the earphone body 110 to complete the replacement.

[0036] In one embodiment, when the wireless earphone 100 is out of power or has low power, the user can replace the entire battery assembly 120. The user's fingers will only touch the sidewall 123 and the drive unit 124 of the battery assembly 120, and will not directly touch the battery unit 121, thus preventing the battery unit 121 from being corroded by the user's sweat. In one embodiment, an insulating material is also provided between the battery unit 121 and the sidewall 123 to achieve a better insulation effect.

[0037] In one embodiment, the battery assembly 120 is additionally rechargeable in the wireless earphone charging case for easy replacement by the user.

[0038] Furthermore, referring to Figure 2, in this embodiment, the outer shell 112 includes a front shell 1121 and a rear shell 1122 connected together. The front shell 1121 has a sound cavity outlet A2 for insertion into the user's ear canal. The rear shell 1122 has the opening A1 and includes an ear stem portion T1.

[0039] Please refer to Figure 3. In this embodiment, the earphone body 110 includes a baffle 113 disposed between the front shell 1121 and the rear shell 1122 to separate a first space P1 and a second space P2. The first space P1 is connected to the sound cavity outlet A2 (Figure 2). The conductive part C1 protrudes from the baffle 113 and extends to the second space P2. The second space P2 is configured to accommodate the battery assembly 120. The first space P1 and the second space P2 are independently separated. Other electronic components of the wireless earphone 100 may be disposed in the first space P1.

[0040] The advantage of this design is that when the battery assembly 120 is removed, the second space P2 is the only independent space exposed to the outside, and the user will not touch or see the other electronic components of the earphone body 110. In this way, when the user replaces the battery assembly 120, other electronic components will not be accidentally touched or damaged.

[0041] In summary, in the wireless earphones of the present invention, the battery assembly is detachably connected to the earphone body. The user can lock or unlock the engagement between the first connector of the earphone body and the second connector of the battery assembly by rotating the drive unit in the rotational direction. In this way, the user can achieve the opening and closing function without tools, simply by rotating the battery assembly relative to the earphone body, facilitating operation and battery replacement. In one embodiment, the first and second electrodes of the battery unit are located on the same surface. Therefore, regardless of the angle at which the user rotates the battery assembly, the conductive part of the earphone body can contact the first and second electrodes to conduct electricity to the battery unit. Furthermore, when the battery assembly is removed, the user will only see the conductive part inside the earphone body and will not touch or see other electronic components of the earphone body. This prevents accidental contact or damage to other electronic components when the user replaces the battery assembly.

[0042] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
