Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to a detachable Bluetooth headphone. Background Technology

[0002] Over-ear headphones are worn on the user's head via a back hook. Currently, the two ends of the back hook are connected to the main body of the headphones, and the connection between the back hook and the main body is fixed. Typically, the back hook and the main body are placed in a mold, and the back hook is attached to the main body through a casting process. This traditional fixed-connection back hook involves placing the back hook and the main body in the mold during production and assembly, pouring silicone, and then allowing it to cool and solidify, resulting in low production efficiency.

[0003] Chinese utility model patent (CN219478115U) discloses a bone conduction headphone with a detachable and replaceable back hook, including a headphone body and a back hook. The headphone body includes a base connected to the back hook, with a socket at one end of the base. A socket terminal electrically connected to the circuitry of the headphone body is located within the socket. The back hook has an insertion part at one end that engages with the socket, with an insertion terminal electrically connected to a wire in the back hook. An elastic latching element is provided between the socket and the insertion part. When the insertion part is inserted into the socket, the insertion terminal is inserted into a terminal hole in the socket and electrically connected to the socket terminal, allowing for a detachable connection between the base and the back hook. The elastic latching element includes: an elastic protrusion on the side of the insertion part and a latching hole on the inner wall of the socket. When the insertion part is inserted into the socket, the elastic protrusion falls into the latching hole, thus limiting the insertion part from the socket. To facilitate detachable separation of the insertion part from the socket, the latching hole is a through hole penetrating the side wall of the socket. This allows for the separation of the insertion part from the socket by applying pressure from the outside of the locking hole inwards to press against the elastic locking protrusion, causing it to retract inwards and disengage from the locking hole.

[0004] This bone conduction headphone achieves a detachable connection between the back hook and the headphone body through the cooperation of the jack and the insertion part. The back hook is inserted axially relative to the headphone body and is locked and separated by elastic clips. A jack terminal is provided on the base of the headphone body, and an insertion terminal is provided on the insertion part of the back hook. The insertion terminal is inserted into the terminal hole in the jack to achieve electrical connection. This connection structure between the headphone body and the back hook is complex, involves many parts, is difficult to assemble, and has a high overall manufacturing cost. Utility Model Content

[0005] The purpose of this utility model is to provide a detachable Bluetooth headset. The back hook and the headset body can be quickly connected and engaged through a plug and a slot. The plug and slot can be separated, allowing the back hook to be detached from the headset body. The back hook and the headset body can be quickly assembled and disassembled through the plug-in engagement, reducing the manufacturing cost of the product and improving the production efficiency of the headset.

[0006] To achieve the above objectives, the technical solution provided by this utility model is: a detachable Bluetooth headset, including a back hook and a headset body, wherein the back hook and the headset body are respectively provided with a plug-in part and a plug-in slot for mutual insertion and cooperation, the plug-in part is laterally inserted into the plug-in slot to make the back hook and the headset body detachably connected, and a locking structure is provided between the plug-in part and the plug-in slot to lock the back hook and the headset body.

[0007] This utility model adopts the above-mentioned technical solution. The back hook is inserted laterally into the insertion slot of the earphone body through the plug-in part. After the connection between the back hook and the earphone body is completed, the plug-in part can be pulled out from the side of the insertion slot, allowing the back hook to be quickly separated from the earphone body. When the plug-in part is inserted into the insertion slot, the back hook and the earphone body are locked and fixed by a locking structure, preventing the earphone body from sliding off the back hook and locking the back hook and the earphone body together. This earphone can be quickly assembled and disassembled, simplifying the complex structure of traditional earphone assembly and disassembly, and has the advantages of convenient operation, high production efficiency, and reduced manufacturing costs.

[0008] The aforementioned detachable Bluetooth headset features a connector slot that extends through the side of the headset body, with the connector inserted into the slot from the side. By aligning the connector with the slot and inserting and pulling it out from the side, the assembly and disassembly of the headband to the headset body can be quickly achieved. This structure, with its connector slot and connector engaging, simplifies the detachable connection between the headset body and the headband, reduces manufacturing costs, and allows for rapid operation.

[0009] In the aforementioned detachable Bluetooth headset, the wall of the plug slot forms a snap-fit ​​groove on the headset body, and a snap-fit ​​part is provided on the side of the plug portion, which snaps into the snap-fit ​​groove. The snap-fit ​​part, engaged in the snap-fit ​​groove, restricts the hook from being inserted into the headset body, preventing the hook from moving away from the headset body.

[0010] The aforementioned detachable Bluetooth headset features a locking structure including a limiting groove on the end face of the headset body and a limiting protrusion on the end face of the rear hook. The connector is inserted into the connecting groove, and the limiting protrusion engages with the limiting groove. When the rear hook is connected to the headset body, the connector is inserted into the connecting groove, and the limiting protrusion engages with the limiting groove, preventing the rear hook from sliding out laterally from the connecting groove, ensuring a secure connection between the rear hook and the headset body. During disassembly, a force is applied along the lateral direction of the headset body to push the limiting protrusion away from the limiting groove, thereby separating the rear hook from the headset body. This enables rapid assembly and disassembly of the rear hook and the headset body, improving product manufacturing efficiency.

[0011] The aforementioned detachable Bluetooth headset features two integrally molded positioning protrusions on the end face of the back hook and two recessed positioning grooves on the end face of the headset body. During insertion into the grooves, the positioning protrusions abut against the end face of the headset body. When fully inserted, the positioning protrusions align and engage with the positioning grooves, securing the back hook to the headset body. For disassembly, a force is applied to the back hook to disengage the positioning protrusions from the positioning grooves, and then the back hook is pushed out of the grooves, completing the detachment of the back hook from the headset body. The positioning protrusions and grooves work together to secure the connection between the back hook and the headset body, preventing the back hook from slipping out of the headset body during use due to lateral forces.

[0012] The aforementioned detachable Bluetooth headset includes a main body and a telescopic part on the back strap, which is adjustable relative to the main body. By adjusting the telescopic part, the length of the back strap can be adjusted to accommodate users with different head shapes, making it more comfortable to wear.

[0013] The aforementioned detachable Bluetooth headset has a telescopic channel within its main body. A connector strip is mounted on the telescopic section, and the portion of the connector strip that inserts into the telescopic channel has several positioning grooves arranged side-by-side. A limiting member is located within the telescopic channel and engages with these positioning grooves. The connector strip is movably inserted into the telescopic channel, and by the limiting member engaging with the corresponding positioning groove, the position of the connector strip within the telescopic channel is adjusted. This, in turn, adjusts the extension position of the telescopic section relative to the main body, thereby adjusting the length of the headset.

[0014] The aforementioned detachable Bluetooth headset features a positioning groove shaped like an arc, with an arc-shaped protrusion on the side wall of the limiting member that abuts against the positioning groove. The arc-shaped protrusion matches the shape of the positioning groove, allowing for better contact within the arc-shaped groove. When the telescopic part is pulled or pushed, the insertion strip moves more smoothly relative to the limiting member, reducing friction and noise.

[0015] In the aforementioned detachable Bluetooth headset, the end of the connector strip inserted into the telescopic channel is bent to form a bend. A baffle is provided inside the telescopic channel. The connector strip moves telescopically within the telescopic channel, and the baffle abuts against the bend to limit the extension length of the telescopic section. By abutting against the bend, the baffle prevents the connector strip from detaching from the telescopic channel.

[0016] The beneficial effects of this invention are as follows: By detachably connecting the back hook to the headphone body, it allows for the replacement of back hooks of different sizes and types, enabling the assembly of different over-ear headphones. The back hook and headphone body are connected via a plug-in joint and a slot, allowing the back hook to be inserted into the slot from the side of the headphone body. This simplifies the complex structure of existing headphone back hook and headphone body connections, enabling quick connection and improving production efficiency during headphone assembly. After connecting the back hook to the headphone body, a locking structure secures the headphone body and back hook together, preventing the back hook from slipping off. During disassembly, the back hook is pulled out from the side of the headphone body, disengaging the plug-in joint from the slot. This plug-in method achieves quick connection and separation of the back hook and headphone body, further improving production efficiency. Attached Figure Description

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1 to 12 As shown, a detachable Bluetooth headset includes a back hook 1 and a headset body 2. The back hook 1 and the headset body 2 are respectively provided with a plug-in part 11 and a plug-in slot 21 that are mutually plugged in and cooperate with each other. The plug-in part 11 is inserted into the plug-in slot 21 from the side, so that the back hook 1 and the headset body 2 are detachably connected. A locking structure is provided between the plug-in part 11 and the plug-in slot 21, and the locking structure locks the back hook 1 and the headset body 2. The plug part 11 is integrally formed on both ends of the back hook 1. The plug groove 21 is opened at the end of the earphone body 2 that connects to the back hook 1. During assembly, the plug part 11 is inserted into the plug groove 21 from the side of the earphone body 2, so that the back hook 1 is connected to the earphone body 2. After the back hook 1 is connected to the earphone body 2, the back hook 1 and the earphone body 2 are locked by the locking structure, so that the back hook 1 and the earphone body 2 will not be separated when not subjected to external force or when worn by the user. During disassembly, a force is applied to the back hook 1, that is, the plug part 11 is pushed laterally, so that the plug part 11 overcomes the limitation of the locking structure and is disengaged from the plug groove 21, thus completing the disassembly of the back hook 1 and the earphone body 2.

[0032] Reference Figure 2As shown, the insertion slot 21 extends through the side of the headphone body 2, and the insertion part 11 is inserted into the insertion slot 21 from the side. The insertion slot 21 is formed at the end of the headphone body 2 that is connected to the rear hook 1. The insertion slot 21 is open in the direction of the rear hook 1 and extends through one side of the headphone body 2. The insertion part 11 can be easily inserted into the insertion slot 21 from the side opening.

[0033] Furthermore, referring to Figure 3 As shown, the groove wall of the plug groove 21 forms a snap-fit ​​groove 22 on the headphone body 2. The side of the plug part 11 is provided with a snap-fit ​​part 12, which snaps into the snap-fit ​​groove 22. The snap-fit ​​groove 22 is located on both sides of the plug groove 21. The snap-fit ​​groove 22 and the end of the headphone body 2 limit the snap-fit ​​part 12 of the plug part 11, so that the back hook 1 cannot move along the axial direction of the headphone body 2, and the back hook 1 is locked on the plug groove 21.

[0034] Reference Figure 2-6 As shown, the locking structure includes a limiting groove 31 on the end face of the earphone body 2 and a limiting protrusion 32 on the end face of the rear hook 1. The insertion part 11 is inserted into the insertion groove 21, causing the limiting protrusion 32 to engage with the limiting groove 31. The limiting groove 31 forms the end face of the earphone body 2, and the limiting protrusion 32 is integrally formed on the rear hook 1, using the same material as the rear hook 1. For example, silicone material can be used. The molded rear hook 1 and limiting protrusion 32 have a certain degree of elasticity. The size and shape of the limiting protrusion 32 are adapted to the limiting groove 31. When the insertion part 11 is inserted into the insertion groove 21, the limiting protrusion 32 engages with the limiting groove 31, thereby fixing the rear hook 1 and the earphone body 2 in place. The earphone body 2 will not slide off the rear hook 1 when no external force is applied. During disassembly, a force is applied to the rear hook 1, causing the plug portion 11 of the rear hook 1 to move in the direction of disengaging from the plug groove 21. When this force overcomes the resistance generated by the limiting protrusion 32 being inserted into the limiting groove 31, the plug portion 11 slides out of the plug groove 21, thereby realizing the removal of the rear hook 1 from the headphone body 2.

[0035] In this embodiment, two limiting protrusions 32 are integrally formed on the end face of the rear hanger 1, and two limiting grooves 31 are recessed in the end face of the earphone body 2. The limiting protrusions 32 and limiting grooves 31 can also play a positioning role when the plug-in part 11 is inserted into the plug-in groove 21.

[0036] In this embodiment, the locking structure engages with the limiting protrusion 32 in the limiting groove 31, thereby locking the connection between the rear hook 1 and the earphone body 2. In other embodiments, the locking structure may employ other methods, such as providing an external thread on the outer periphery of the end of the rear hook 1 that connects to the earphone body 2, and then connecting the rear hook 1 to the earphone body 2 via a sleeve threaded with an internal thread to the outer periphery of the insertion part and the insertion groove, thereby achieving the locking of the rear hook 1 and the earphone body 2. The locking structure includes, but is not limited to, the above-described embodiments, and can be selected according to actual needs.

[0037] Reference Figure 4-10 As shown, the rear hanger 1 includes a main body 13 and a telescopic part 14, which can be telescopically adjusted relative to the main body 13. Specifically, the main body 13 has a telescopic channel 131, and the telescopic part 14 has an insertion strip 141. The portion of the insertion strip 141 that inserts into the telescopic channel 131 has several positioning grooves 142 arranged side by side. The telescopic channel 131 has a limiting member 132 that abuts against the positioning grooves 142. It should be understood that the number of positioning grooves 142 is set according to the design requirements of the rear hanger 1, and the number is set to at least two. The number is selected according to the actual size and design requirements of the rear hanger 1. In this embodiment, there are seven positioning grooves 142. In other embodiments, the number of positioning grooves 142 can also be set to other numbers. During implementation, the limiting member 132 abuts against the positioning groove 142, limiting the position of the connector 141. When the telescopic part 14 needs adjustment, it is pulled or pushed, causing the connector 141 to slide in the telescopic channel 131. The positioning groove 142 pushes the limiting member 132, allowing it to disengage from the limiting groove 142. After adjusting the extension position of the telescopic part 14, the limiting member 132 abuts against its corresponding positioning groove 142, limiting the position of the telescopic part 14 relative to the main body 13 when no external force is applied. It should be understood that the limiting member 132 is elastic, with both ends embedded in the sidewall of the telescopic channel 131, exposing its arc-shaped protrusion 133 to abut against the positioning groove 142.

[0038] In other embodiments, the telescopic part 14 can be extended or retracted relative to the main body 13 in other ways. For example, the telescopic part 14 can be sleeved on the outer periphery or inside the main body 13 and can move along the axial direction of the main body 13. When it extends to the corresponding position, it can be fixed by a snap-fit ​​connection or the telescopic part 14 can be threaded to the main body 13. The extension and retraction of the telescopic part 14 can be achieved by the threaded follow-up, thereby adjusting the length of the rear hanger 1.

[0039] like Figure 9 and Figure 10 As shown, the positioning groove 142 is configured as an arc-shaped groove, and the side wall of the limiting member 132 protrudes to form an arc-shaped protrusion 133, which abuts against the positioning groove 142. The arc-shaped protrusion 133 matches the shape of the positioning groove 142, and the surface of the arc-shaped protrusion 133 fits the arc surface of the positioning groove 142. When the telescopic part 14 is pushed or pulled, the insertion strip 141 moves in the telescopic channel 131, and the movement of the insertion strip 141 relative to the limiting member 132 is smoother and more fluid.

[0040] See Figure 7 , 8As shown, the end of the connector 141 inserted into the telescopic channel 131 is bent to form a bend 143. A baffle 134 is provided inside the telescopic channel 131. The connector 141 moves telescopically in the telescopic channel 131. The baffle 134 abuts against the bend 143 to limit the extension length of the telescopic section 14.

[0041] Combination Figure 5 As shown, the main body 13 is provided with a cover plate 135, which covers the telescopic channel 131. After inserting the connector 141 into the telescopic channel 131, the cover plate 135 is placed on the main body 13 and covers the telescopic channel 131. The cover plate 135 is fixed to the main body 13 by ultrasonic welding. Inserting the connector 141 first and then covering the cover plate 135 facilitates the assembly of the telescopic part 14 and the main body 13.

[0042] Reference Figure 2 , 11 As shown in Figure 12, the headphone body 2 includes a mechanism assembly 23, a power supply assembly 24, and a connecting part 25 connecting the mechanism assembly 23 and the power supply assembly 24. The connecting part 25 can be hung on the user's ear, and the mechanism assembly 23 is aligned with the ear canal. The mechanism assembly 23 includes an upper mechanism shell 231 and a lower mechanism shell 232. The upper mechanism shell 231 and the lower mechanism shell 232 are assembled together to form a mechanism shell. The lower mechanism shell 232 fits the user's ear. The mechanism assembly 23 includes a circuit board 233 and a speaker 234 placed in the inner cavity enclosed by the upper mechanism shell 231 and the lower mechanism shell 232. The speaker 234 is connected to the circuit board 233. A dustproof mesh 2321 corresponding to the speaker 234 is provided on the lower mechanism shell 232 to conduct sound and prevent dust.

[0043] A charging post 235 is provided on the circuit board 233. The outer end of the charging post 235 protrudes from the lower shell 232 of the mechanism. There are two charging posts 235. An adsorption magnet 236 is provided between the charging posts 235. The adsorption magnet 236 is used to adsorb onto the charging case when the earphone is charging, so that the charging post 235 and the charging pin of the charging case are in close contact.

[0044] The circuit board 233 is provided with a touch pin 237 and a touch sheet 238. The touch pin 237 passes through the touch sheet 238 and abuts against the upper shell 231 of the mechanism. The touch pin 237 and the touch sheet 238 cooperate to enable the headphones to be controlled by touch.

[0045] A light guide post 239 is provided on the circuit board 233. One end of the light guide post 239 protrudes from the upper shell 231 of the mechanism, and the other end is aligned with the indicator light on the circuit board 233 for light display. A microphone 2310 is provided on the circuit board 233 to pick up the user's voice and realize the call function of the headset.

[0046] The power assembly 24 includes a battery housing 241 and a battery 242, wherein the battery 242 is connected to the circuit board 233 via wires 26. An elastic metal wire 27 is threaded through the connecting portion 25, with both ends of the elastic metal wire 27 connected to the battery housing 241 and the upper casing 231 or lower casing 232 of the mechanism. A first connecting block 28 is formed at the end of the battery housing 241, and a second connecting block 29 is formed at the end of the upper casing 231 and lower casing 232 of the mechanism. Both ends of the elastic metal wire 27 are inserted into the first connecting block 28 and the second connecting block 29 and can be cast. The first connecting block 28 and the second connecting block 29 have through-holes for the wires 26 to pass through, allowing the wires 26 to extend into the battery housing 241, the upper casing 231, and the lower casing 232 of the mechanism to connect the battery 242 and the circuit board 233. The connecting part 25 is formed by an integrally molded silicone outer shell around the first connecting block 28, the second connecting block 29, the elastic metal wire 27 and the wire 26. The elastic metal wire 27 makes the connecting part 25 elastic, making it more comfortable for the user to wear.

[0047] A magnetic magnet 243 is also provided inside the battery housing 241, which can be used to magnetically attract the charging case when the earphones are charging, and fix the position of the power assembly 24.

[0048] This invention achieves rapid assembly and improves production efficiency through the detachable connection between the back hook 1 and the headphone body 2. Different types and shapes of back hooks can also be replaced according to different usage needs, thus assembling different over-ear headphones. Specifically, a connector slot 21 is provided on the battery housing 241 of the headphone body 2, and connector parts 11 are provided at both ends of the back hook 1. The connector parts 11 are inserted into the connector slot 21, thereby connecting the back hook 1 and the headphone body 2. This achieves rapid connection between the back hook 1 and the headphone body 2, simplifies the structure, and reduces the manufacturing cost of the headphones. After the connector parts 11 are inserted into the connector slot 21, in this embodiment, limiting protrusions 32 are used to correspondingly engage with the limiting slots 31, thereby locking and fixing the connection between the back hook 1 and the headphone body 2, preventing the headphone body 2 from slipping off the back hook 1 when worn. When the plug part 11 is inserted into the plug groove 21, a snap-fit ​​part 12 is provided on the plug part 11, and a snap-fit ​​groove 22 is provided in the plug groove 21. The snap-fit ​​part 12 snaps into the snap-fit ​​groove 22 and is restricted by the groove wall of the snap-fit ​​groove 22 to prevent the back hook 1 from moving along the axial direction of the headphone body 2. Combined with the locking structure, the back hook 1 and the headphone body 2 can be firmly connected.

[0049] The length of the rear hanger 1 can be adjusted during use. Pulling the telescopic part 14 outward relative to the main body 13 extends the length of the rear hanger 1, while pushing the telescopic part 14 inward relative to the main body 13 shortens the length of the rear hanger 1, providing flexibility. Specifically, the telescopic part 14 is provided with a connector 141 that is movably inserted into the telescopic channel 131 within the main body 13. A positioning groove 142 is provided on the connector 141, and a limiting member 132 is provided in the telescopic channel 131. When the limiting member 132 abuts against the positioning groove 142, it maintains the position of the connector 141 inserted into the telescopic channel 131 without external force, thereby adjusting the position of the telescopic part 14 relative to the main body 13 and thus achieving length adjustment of the rear hanger 1.

[0050] This invention features quick assembly and disassembly of the back hook and the main body of the earphone, enabling rapid replacement and improving production efficiency; it also allows for adjustment of the back hook length to accommodate users with different head shapes, thus broadening its application range.
