Description

Technical Field

[0001] This utility model relates to wearable electronic devices, and more specifically, to an earphone assembly. Background Technology

[0002] With the rapid development of technology, wearable electronic devices such as true wireless stereo (TWS) earphones, smartwatches, and smart bracelets have increasingly become an indispensable part of daily life. These electronic devices have brought great convenience to people's daily lives, but the non-removable battery technology they use has brought a series of problems.

[0003] First, battery performance begins to decline after a certain number of charge-discharge cycles. For example, frequently used TWS earbuds may last for 5-6 hours when first purchased, but after a year or less of use, their battery life may be reduced to only 3-4 hours or even less. Such a decline in battery performance seriously affects the user experience.

[0004] Secondly, the current non-removable battery design limits the lifespan of electronic devices as battery performance deteriorates. Some users may choose to replace the entire device due to reduced battery life, which undoubtedly increases the amount of electronic waste and puts considerable pressure on the environment.

[0005] In recent years, environmental protection has become a global focus. To reduce electronic waste and encourage the long-term use of devices, some countries have proposed requirements for removable batteries, hoping that manufacturers can design electronic devices with easily replaceable batteries, thereby extending the lifespan of electronic devices and reducing electronic waste.

[0006] However, there is currently a lack of unified standards or solutions in the market regarding how to design a simple, reliable, and aesthetically pleasing method for battery removal and replacement. Therefore, a new technology is needed to meet the above requirements in order to achieve simple, reliable, and aesthetically pleasing removal and replacement of batteries for wearable electronic devices.

Figure 1A-1B In the illustrated embodiment, the earphone assembly 100 is a TWS earphone. In other embodiments according to the present invention, the earphone assembly 100 can be any suitable wireless earphone.

[0039] Figure 2A-2B This is an exploded view of an earphone assembly 100 according to one or more embodiments of the present invention. As shown, the battery compartment 120 is a recess formed at the rear of the earphone body 110, including a compartment bottom 122 and a compartment sidewall 124 defining the recess. In the embodiment shown, the compartment bottom 122 is flat, and the compartment sidewall 124 extends axially upward from the compartment bottom 122, generally perpendicular to the compartment bottom 122. In another embodiment according to the present invention, the compartment bottom 122 and the compartment sidewall 124 may have any suitable shape and structure, as long as they define a suitable battery compartment.

[0040] Electrical connection terminals 126 are arranged at the bottom 122 of the compartment, and multiple first connection structures 130 are arranged on the side wall 124 of the compartment. In the embodiment shown in the figure, two electrical connection terminals 126 are arranged on the bottom 122 of the compartment, one of which is centrally located on the bottom 122 of the compartment, and the other is spaced apart from the centrally located electrical connection terminal 126. Correspondingly, the battery 160 of the headphone assembly 100 includes a centrally located first electrode 166 and an annular second electrode 168 spaced apart from and surrounding the first electrode 166 on its bottom surface. Since the second electrode 168 of the battery 160 is annular, when the battery 160 is placed in the battery compartment 120, the first electrode 166 and the second electrode 168 of the battery 160 can respectively contact and be electrically connected with the two electrical connection terminals 126 on the bottom 120 of the compartment, regardless of the specific placement angle of the battery 160.

The second connection structures 150 of the side wall portion 144 of the battery cover 140 correspond to and are adapted to cooperate with the first connection structures 130 on the side wall 124, thereby securely and detachably connecting the battery cover 140 to the battery compartment 120, thereby securely holding the battery 160 in the battery compartment 120.

[0042] The headphone assembly 100 also includes a sealing ring 170. The sealing ring 170 is received in a corresponding annular groove in the side wall portion 144 of the battery cover 140. When the battery cover 140 is connected to the battery compartment 120, the sealing ring 170 is tightly fitted between the side wall portion 144 of the battery cover 140 and the side wall 124 of the battery compartment 120, providing a seal for the battery compartment 120 and the battery 160 therein.

[0043] A bracket 148 is also arranged or formed on the inner side of the top cover portion 142 of the battery cover 140. The bracket 148 is adapted to contact and engage with the top surface of the battery 160, thereby holding the battery 160 in the battery compartment 120.

[0044] Figure 3An earphone assembly 100 according to one or more embodiments of the present invention is shown. Figure 1B The cross-sectional view is shown by arrows 3A-3A. Between the bottom surface of the battery 160 and the bottom 122 of the compartment, the first electrode 166 and the second electrode 168 of the battery 160 contact and are electrically connected to two electrical connection terminals 126 on the bottom 122 of the compartment, respectively. This allows the battery 160 to be electrically connected to and powered by electronic devices (including speakers, etc.) inside the headphone assembly 100. Multiple first connection structures 130 on the side wall 124 of the compartment are interconnected with multiple second connection structures 150 on the side wall portion 144 of the battery cover 140, achieving a detachable and secure connection between the battery cover 140 and the battery compartment 120, thereby detachably and securely holding the battery 160 within the battery compartment 120. Furthermore, a sealing ring 170 between the side wall portion 144 of the battery cover 140 and the side wall 124 of the battery compartment 120 provides a seal, preventing water or dust from entering the battery compartment 120.

[0045] like Figure 3 As shown and combined Figure 2A-2B The battery compartment 120 of the earphone body 110 includes only electrical connection terminals 126 and a first connection structure 130 on its bottom 122 and side walls 124, without any other protruding or recessed structures. This achieves a simple and independent removable battery compartment structure. This simple and compact structure of the earphone body, in... Figure 2A-2B Even after removing the battery 160 and battery cover 140, the structure remains intact, which improves the waterproofness, electronic design, and overall quality of the headphone body 110.

[0046] In addition, such as Figure 3 As shown and combined Figure 2A-2B The top cover portion 142 and the side wall portion 144 of the battery cover 140 are integrally formed, providing good structural integrity. In the assembled position, the side wall portion 144 of the battery cover 140 extends to or contacts the bottom 122 of the battery compartment 120.

Furthermore, the sealing ring 170 between the side wall portion 144 of the battery cover 140 and the side wall 124 of the battery compartment 120 ensures good sealing performance.

[0047] Figure 4A This is an exploded view of an earphone assembly 100 according to one or more embodiments of the present invention. Figure 4B yes Figure 4A A magnified view of a portion of the view. Figure 4C yes Figure 4A Another magnified view of a portion of the view.

[0048] like Figure 4B As shown, a plurality of second connecting structures 150 are formed circumferentially on the sidewall portion 144 of the battery cover 140. In one or more embodiments of the present invention, two, three, four or more second connecting structures 150 may be formed on the sidewall portion 144 of the battery cover 140. In one or more embodiments of the present invention, the second connecting structure 150 includes a first groove 156 and a second groove 158 formed on the outer side of the sidewall portion 144 of the battery cover 140. The first groove 156 communicates with the second groove 158. In one or more embodiments of the present invention, the first groove 156 extends axially to the axially lower end of the sidewall portion 144. The second groove 158 is spaced apart from the axially lower end of the sidewall portion 144 and extends substantially circumferentially, thereby defining a circumferentially extending rib 152. The second groove 158 is defined between the rib 152 and the sidewall portion 154. The rib 152 here is a raised rib naturally left by forming the first groove 156 and the second groove 158 on the side wall portion 144 of the battery cover 140. In one or more embodiments according to the present invention, the rib 152 has a boss 152a formed on its axially upward side. In one or more embodiments according to the present invention, the boss 152a has a small protrusion height, for example, about 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm or 0.5 mm.

[0049] like Figure 4C As shown, a plurality of first connecting structures 130 are formed on the side wall 124 of the battery compartment 120. The number of first connecting structures 130 on the side wall 124 of the battery compartment 120 corresponds to the number of second connecting structures 150 on the side wall portion 144 of the battery cover 140. In one or more embodiments of the present invention, two, three, four or more first connecting structures 130 may be formed on the side wall 124 of the battery compartment 120. In one or more embodiments of the present invention, the first connecting structure 130 is in the form of a rib 130 that protrudes radially inward from the side wall 124 of the battery compartment 120. In one or more embodiments of the present invention, the rib 130 has a boss 132 formed on its axially lower side. In one or more embodiments of the present invention, the boss 152a has a small protrusion height, for example, about 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm or 0.5 mm.

[0050] In one or more embodiments of the present invention, the dimensions of the first groove 156 and the second groove 158 on the side wall portion 144 of the battery cover 140 are configured to receive the protrusion 130 on the side wall 124 of the battery compartment 120. For example, the circumferential dimension of the first groove 156 on the side wall portion 144 of the battery cover 140 may be equal to or slightly larger than the circumferential dimension of the protrusion 130 on the side wall 124 of the battery compartment 120, so as to allow the protrusion 130 to enter the first groove 156 axially, thereby moving to a position aligned with the second groove 158. The axial dimension of the second groove 158 on the side wall portion 144 of the battery cover 140 may be equal to or slightly larger than the axial dimension of the protrusion 130 on the side wall 124 of the battery compartment 120, so as to allow the protrusion 130 to rotate circumferentially into the second groove 158.

[0051] The boss 132 on the rib 130 and the boss 152a on the rib 152 prevent the rib 130 from accidentally disengaging from the second groove 158 when the rib 130 engages with the second groove 158. Furthermore, the protrusion height of the boss 132 on the rib 130 and the boss 152a on the rib 152 is sufficiently small to allow the rib 130 to disengage from the second groove 158 under appropriate external force.

[0052] When installing the battery cover 140, first align the battery cover 140 with the battery compartment 120 of the earphone body 110, so that the first groove 156 of the battery cover 140 aligns with the protrusion 130 of the battery compartment 120. Then, insert the battery cover 140 axially into the battery compartment 120. At this time, the protrusion 130 on the side wall 124 of the battery compartment 120 passes axially through the first groove 156 and reaches a position aligned with the second groove 158. Then, along... Figure 4B Rotate the battery cover 140 in the direction indicated by arrow 4B so that the protrusion 130 of the battery compartment 120 enters the second groove 158 of the battery cover 140, thereby firmly holding the battery cover 140 connected to the battery compartment 120 of the headphone body 110.

[0053] The boss 132 on the rib 130 and the boss 152a on the rib 152 prevent the rib 130 from accidentally dislodging from the second groove 158. Furthermore, the protrusion height of the boss 132 on the rib 130 and the boss 152a on the rib 152 is sufficiently small to allow the rib 130 to dislodge from the second groove 158 under external force. In addition, the sealing ring 170 on the headphone cover 140 is tightly fitted between the side wall 144 of the battery cover 140 and the side wall 124 of the battery compartment 120, providing a seal for the battery compartment 120 and the battery 160 therein.

[0054] In the embodiment shown, the sidewall 124 of the battery compartment 120 is smooth and has no other protrusions except for the rib 130. The sidewall 144 of the battery cover 140 is also substantially smooth, except for the groove for receiving the sealing ring 170 and the first groove 156 and the second groove 158 for forming the second connection structure 150. Therefore, the sidewall 144 of the battery cover 140 and the sidewall 124 of the battery compartment 120 mate substantially over the entire mating surface, and in some embodiments fit tightly together. This improves the structural integrity, sealing, and aesthetics of the entire headphone assembly 100.

[0055] The first connecting structure 130 and the second connecting structure 150 shown in the figure are exemplary. In one or more embodiments according to the present invention, the first groove 156 and the second groove 158 of the second connecting structure 150 may have different shapes and structures, as long as the first groove 156 allows the protruding rib 130 of the battery compartment 120 to pass through and the second groove 168 can engage with the protruding rib 130. In one or more embodiments according to the present invention, the first connecting structure 130 and the second connecting structure 150 may be any suitable snap-fit ​​structure, latch, or connection structure, as long as it can reliably and detachably connect the battery cover to the battery compartment 120 of the earphone body 110.

[0056] Figure 5A The headphone assembly 100 according to one or more embodiments of the present invention is along Figure 1B The sectional view taken by arrow 5A-5A. Figure 5B yes Figure 5A An enlarged view of part 5B is shown. As illustrated, the protruding rib 130 on the side wall 124 of the battery compartment 120 is received in the second groove 158 of the side wall portion 144 of the battery cover 140, thereby limiting the axial movement of the protruding rib 130 of the battery compartment 120 by the protruding ribs 152 on both sides of the second groove 158 of the battery cover 140 and the side wall portion 154. This prevents the battery cover 140 from moving axially relative to the battery compartment 120.

[0057] Furthermore, the boss 132 on the rib 130 and the boss 152a on the rib 152 prevent the rib 130 from accidentally rotating circumferentially and disengaging from the second groove 158. The protrusion height of the boss 132 on the rib 130 and the boss 152a on the rib 152 is sufficiently small, and ramps are formed on both sides, thereby allowing the rib 130 to disengage from the second groove 158 when the user forcefully rotates the battery cover 140.

[0058] Figures 6A-6BThis is a perspective view of an earphone assembly 100 according to one or more embodiments of the present invention, showing how to remove the battery cover 140 using a tool needle 20. As shown, a removal hole 146 is formed on the battery cover. The removal hole 146 has a diameter corresponding to the tool needle 20. When it is necessary to replace the battery from the earphone assembly 100, the tool needle 20 is aligned with and inserted into the removal hole 146 of the battery cover 140. The battery cover 140 is then rotated in the desired direction so that the rib 130 on the side wall 124 of the battery compartment 120 disengages from the second groove 158 of the side wall portion 144 of the battery cover 140, thereby removing the battery cover 140 from the earphone assembly 100 for battery replacement. In one or more other embodiments according to the present invention, the removal hole 146 on the battery cover and the tool needle 20 are not necessary.

[0059] In one or more embodiments of the present invention, a commercially available headphone assembly or battery replacement kit may include tools and spare parts. These tools and spare parts include tool pins 20 and spare parts for the battery 160, etc. In other embodiments of the present invention, the battery replacement kit may be sold together with the headphone assembly or may be sold separately.

[0060] In the embodiments shown above, the battery is cylindrical, and the battery cover and battery compartment are shaped to accommodate the cylindrical battery. This invention is not limited thereto; in one or more other embodiments according to this invention, the battery, battery cover, and battery compartment may have any suitable shape and structure, as long as they securely hold the battery and facilitate the removal of the battery from the battery compartment and the reinstallation of a new battery into the battery compartment.

[0061] In the embodiment shown above, the battery compartment 120 and its opening are arranged at the rear of the earphone body 110 of the earphone assembly 100, away from the ear inlet 112, through which the battery 160 is installed and removed. In one or more other embodiments according to the present invention, the battery compartment and its opening may be arranged in other suitable locations on the earphone.
