Description

Technical Field

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

[0002] Normally, the sound we hear is transmitted through the air via the outer ear to the eardrum. The vibrations in the eardrum then stimulate the auditory nerve, allowing us to perceive the sound. However, in existing bone conduction headphones, the back hook is glued into the housing. Under strong tension, the back hook can detach, causing the wires running through it to come loose. Furthermore, the large amount of glue between the back hook and the main housing leads to glue overflow, making it impossible to accurately test the bonding strength during mass production. Utility Model Content

[0003] The purpose of this utility model is to provide a bone conduction headphone in which the headphone's back-hook assembly is inserted into the core housing via a connector. The connector is locked into the core housing during rotation and then fixedly connected, ensuring a strong and secure connection between the back-hook assembly and the core housing, preventing them from detaching.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a bone conduction earphone, including a rear hook assembly and ear hook assemblies respectively connected to both ends of the rear hook assembly. The ear hook assembly includes a core housing, an ear hook, and a speaker housing. The core housing and the speaker housing are connected by the ear hook. The tail end of the core housing is provided with a plug hole. Both ends of the rear hook assembly are provided with plug parts. The plug parts are inserted into the plug holes and rotate axially and are fixedly connected, so that the rear hook assembly and the ear hook assembly are fixedly connected.

[0005] This utility model adopts the above-mentioned technical solution, in which the plug part and the plug hole cooperate, so that the plug part can rotate axially when inserted into the plug hole, so that the plug part is stuck in the plug hole and cannot move linearly along the axis in the plug hole. Then, it is fixed by means of injecting glue, so that the rear hanging component and the ear hook component can be firmly connected and prevent the rear hanging component and the ear hook component from separating. In mass production, the connection efficiency of the ear hook component and the rear hanging component is guaranteed and the quality is stable.

[0006] The aforementioned bone conduction headphones have a glue-filling groove in the core housing that connects to the plug-in hole. The plug-in part passes through the plug-in hole and extends into the glue-filling groove. Glue is poured into the glue-filling groove or a locking component is installed, so that the plug-in part is fixedly connected to the plug-in hole under the action of glue or locking component. The plug-in part passes through the plug-in hole and its end extends into the glue-filling groove. Glue can be poured into the glue-filling groove to make the plug-in part and the plug-in hole firmly connected, or the plug-in part can be fixed in the plug-in hole by setting a locking component, so that the two are firmly connected. After the plug-in part is inserted into the plug-in hole and then rotated to limit the position of the plug-in part, the plug-in part cannot be pulled out of the plug-in hole. Combined with glue or locking component, the connection between the plug-in part and the plug-in hole is firmly connected, which effectively improves the connection strength between the rear-mounted component and the core housing.

[0007] The aforementioned bone conduction headphones have a groove on the wall of the connector hole and a protrusion on the side wall of the connector. After the connector is inserted into the connector hole, it rotates axially. The protrusion slides through the groove and then locks into the wall of the glue injection groove after rotation. The groove in the connector hole engages with the protrusion of the connector to position the connector for insertion. After the connector is inserted into the connector hole, it rotates at an angle, causing the protrusion to misalign with the groove and lock into the wall of the glue injection groove. This prevents the connector from being pulled out of the connector hole axially, thus improving the connection strength between the rear mounting assembly and the core housing.

[0008] In the aforementioned bone conduction headphones, the glue injection groove is composed of an integrally molded L-shaped partition that surrounds the inner sidewall and bottom wall of the core housing. The partition is integrally molded on the core housing, forming a glue injection groove together with the sidewall and bottom wall. The end of the plug-in part extends into the glue injection groove, and after rotation, the protrusion is locked against the groove wall. Glue is then injected to fix the end of the plug-in part in the glue injection groove, achieving a tight connection between the plug-in part and the plug hole.

[0009] The aforementioned bone conduction headphones have mounting slots at both ends of the rear-hook assembly. The tail end of the connector is inserted into the mounting slot and fixedly connected. The connector can be fixedly connected to the rear-hook assembly by gluing or by integral molding.

[0010] The aforementioned bone conduction headphones include a connector portion comprising a connecting fixing section, a first insertion section, and a second insertion section. The connecting fixing section is inserted into a mounting groove. The first insertion section is connected to the connecting fixing section. The second insertion section extends axially relative to the first insertion section, with a protrusion on its outer wall. The diameter of the second insertion section is smaller than that of the first insertion section. The connector is inserted into a connector hole. After passing through the connector hole, the second insertion section extends into a glue injection groove. The protrusion is engaged with the wall of the glue injection groove, preventing the connector from being pulled out axially from the connector hole, thus improving the connection strength between the rear hook assembly and the ear hook assembly.

[0011] The aforementioned bone conduction headphones have a first hole segment and a second hole segment formed within the plug hole to receive the first insertion segment and the second insertion segment, respectively. The plug hole is equipped with a first hole segment and a second hole segment that match the first insertion segment and the second insertion segment, allowing for better fit of the plug and enabling quick insertion of the plug.

[0012] The aforementioned bone conduction headphones include a back-hook assembly comprising an elastic metal wire and an elastic covering layer over the elastic metal wire, with a mounting groove located at the end of the elastic covering layer. The elastic covering layer encapsulates the elastic metal wire, allowing the back-hook assembly to possess a certain degree of elasticity.

[0013] The aforementioned bone conduction headphones have wires threaded through the rear-hook assembly, with an elastic cover covering the wires. The two ends of the wires extend into the two internal housings of the headphone mechanism. The wires connect to the electronic components within the housings, providing electrical conductivity and signal transmission to enable the headphones to vibrate and produce sound.

[0014] The aforementioned bone conduction headphones have a battery unit and a driver unit housed in two separate housings. A horn is located inside the speaker housing. The battery unit is connected to the driver unit via wiring, and the driver unit is connected to the horn via wiring. The driver unit drives the horn to vibrate. The battery unit provides power to the driver unit, which in turn drives the horn to vibrate. The speaker housing is placed against the user's skin, allowing the user to hear sound through bone conduction.

[0015] The beneficial effects of this utility model are as follows: By providing a plug-in part on the rear hanging assembly and a plug-in hole on the mechanism, the plug-in part and the plug-in hole are engaged through the plug-in cooperation, and the plug-in part is inserted into the plug-in hole and rotated to lock into the plug-in hole, locking the plug-in part so that it can no longer move axially and is limited to not being pulled out of the plug-in hole. This enhances the connection strength between the rear hanging assembly and the ear hook assembly, avoids the wire being pulled out due to force, and ensures reliable connection and stable quality.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figures 1 to 13As shown, the bone conduction headphones of this utility model embodiment include a rear hook assembly 1 and ear hook assemblies 2 connected to both ends of the rear hook assembly 1. Each ear hook assembly 2 includes a core housing 21, a speaker housing 23, and an ear hook 22 connecting the core housing 21 and the speaker housing 23. The two core housings 21 are respectively provided with a battery unit 31 and a drive unit 32. The speaker housing 23 is provided with a vibrating speaker 33. The battery unit 31 provides power to the drive unit 32, and the drive unit 32 drives the vibrating speaker 33 to vibrate and produce sound.

[0033] The speaker housing 23 has a vibrating speaker 33 inside and a speaker housing cover 24 on the speaker housing 23. The mechanism housing 21 has a receiving cavity 210 inside and a mechanism housing cover 25 on top of it. The drive unit 33 is connected to the vibrating speaker 33 through wires and drives the vibrating speaker 33 to vibrate.

[0034] The accommodating cavity 210 houses a circuit board 34, a charging spring 38, a magnet 39, a TF memory card 40, and a microphone 41, which together constitute the driving unit 32. In this embodiment, the circuit board 34 is connected to the vibrator speaker 33 via wires.

The TF memory card 40 is used to store music, the microphone 41 is used to enable the headset's call function, and the magnet 39 is used to attract and keep the charging spring 38 connected to the charging unit, thus enabling the charging function.

[0035] The circuit board 34 is equipped with an LED lamp 35, and the housing 21 of the mechanism is equipped with a light guide post 36 corresponding to the LED lamp 35, so that the light emitted by the LED lamp 35 is guided out from the light guide post 36.

[0036] The battery unit 31 includes a battery 311 and a welding adapter plate 312. The welding adapter plate 312 is connected to the battery 311 to facilitate wire connection to the battery 311.

[0037] In existing headphones, during assembly, the end of the back hook assembly 1 is inserted into the end of the ear hook assembly 2, and then the connection between the back hook assembly 1 and the ear hook assembly 2 is usually achieved by gluing. The wire extends into the inner housing 21 of the main body to connect the sound unit 32 and the battery unit 31. However, due to the strength of the glue bond, it is prone to delamination and wire detachment under strong tensile force, and the use of a large amount of glue can easily lead to glue overflow. Furthermore, it is difficult to accurately test the bonding strength during mass production.

[0038] Reference Figures 1 to 13As shown, this utility model discloses a bone conduction earphone, including a rear hook assembly 1 and ear hook assemblies 2 connected to both ends of the rear hook assembly 1. The ear hook assembly 2 includes a core housing 21, ear hooks 22, and a speaker housing 23. The core housing 21 and the speaker housing 23 are connected by the ear hooks 22. The tail end of the core housing 21 is provided with a insertion hole 211. Both ends of the rear hook assembly 1 are provided with insertion parts 11. The insertion parts 11 are inserted into the insertion holes 211 and rotate axially and are fixedly connected, thereby fixing the rear hook assembly 1 and the ear hook assembly 2 together. In a specific implementation, protrusions, buckles, or other structures can be provided on the insertion parts 11. During rotation, the protrusions or buckles are engaged with the ends of the insertion holes 211 due to misalignment, limiting the axial movement of the rear hook assembly 1 relative to the ear hook assembly 2. Then, glue is injected for bonding, which enhances the connection strength between the rear hook assembly 1 and the ear hook assembly 2. In other embodiments, the way to lock the plug part 11 to the plug hole 211 by rotating it can also be by threading the plug part 11 to the plug hole 211 and then fixing it with glue, which also enhances the connection strength between the rear hanging assembly 1 and the ear hook assembly 2.

[0039] Combination Figure 8 As shown, the movement housing 21 has a glue injection groove 212 that connects to the insertion hole 211. The insertion part 11 passes through the insertion hole 211 and extends into the glue injection groove 212. Glue is injected into the glue injection groove 212 or a locking component is installed, so that the insertion part 11 is fixedly connected to the insertion hole 211 under the action of glue or the locking component. The glue injection groove 211 is open on one side and connects to the insertion hole 211. When the insertion part 11 passes through the insertion hole 211 and extends into the glue injection groove 212, it is convenient to inject glue or fix the insertion part 11 in the insertion hole 211 by setting a locking component.

[0040] Combination Figure 9 As shown, the wall of the insertion hole 211 is provided with a groove 213, and the side wall of the insertion part 11 is provided with a protrusion 114. After the insertion part 11 is inserted into the insertion hole 211, it rotates axially. The protrusion 114 slides through the groove 213 and is locked in the groove wall of the glue injection groove 212 after rotation. During the process of inserting the rear hanging component 1 into the insertion hole 211, the protrusion 114 is aligned with the groove 213, so that the insertion part 11 is smoothly inserted into the insertion hole 211. The protrusion 114 extends into the glue injection groove 213. Then, by rotating the insertion part 11, the protrusion 114 is misaligned with the groove 213 and locked in the groove wall of the glue injection groove 213, which limits the insertion part 11 from being pulled out axially from the insertion hole 211, thereby avoiding the problem of the wires being easily detached due to external force.

[0041] Combination Figure 8-10As shown, the glue injection groove 212 is composed of an integrally formed L-shaped partition 214 surrounding the inner wall and bottom wall of the movement housing 21. The partition 214 is L-shaped, with its two ends integrally formed and fixed to the inner wall of the movement housing 1. The bottom of the partition 214 is integrally formed on the inner wall of the movement housing 21, forming a groove with an opening. When the insertion part 11 is inserted into the glue injection groove 213, the protrusion 114 is located in the glue injection groove 213. Then, glue is injected to fix the insertion part 11 in the insertion hole 211.

[0042] Combination Figure 6 As shown, the rear mounting component 1 has mounting slots 12 at both ends, and the tail end of the plug-in part 11 is inserted into the mounting slots 12 and fixedly connected.

[0043] like Figure 11 As shown, the plug-in part 11 includes a connecting and fixing section 113, a first insertion section 111 and a second insertion section 112. The connecting and fixing section 113 is inserted into the mounting groove 12. The first insertion section 111 is connected to the connecting and fixing section 113. The second insertion section 112 extends axially relative to the first insertion section 111. A protrusion 114 is provided on the outer wall of the second insertion section 112.

[0044] Figure 10 As shown, the insertion hole 211 has a first hole segment 215 and a second hole segment 216 formed therein to receive the first insertion segment 111 and the second insertion segment 112, respectively. When the insertion part 11 is inserted into the insertion hole 211, the first hole segment 215 receives the first insertion segment 111 and the second hole segment 216 receives the second insertion segment 112.

[0045] Reference Figure 6 As shown, the rear mounting assembly 1 includes an elastic metal wire 13 and an elastic coating 14 covering the elastic metal wire 13. Mounting grooves 12 are located at the ends of the elastic coating 14. A wire 15 is threaded through the rear mounting assembly 1, and the elastic coating 14 wraps around the wire 15. Both ends of the wire 15 extend into the two mechanism housings 21, respectively. The wire 15 is first fixed to the elastic metal wire 13. Then, the elastic metal wire 13 and the wire 15 are placed in a mold, and the elastic coating 14 is cast onto the surfaces of the elastic metal wire 13 and the wire 15. Mounting grooves 12 are formed at both ends of the elastic coating 14. The connecting and fixing sections 113 of the insertion part 11 are inserted into the mounting grooves 12 for shaping. This process can also be implemented using a casting molding technique.

[0046] In this embodiment, a battery unit 31 and a drive unit 32 are respectively installed in the two core housings 21. A vibrator horn 33 is provided in the horn housing 22. The battery unit 31 is connected to the drive unit 32 by wiring, and the drive unit 32 is connected to the vibrator horn 33 by wiring. The drive unit 32 drives the vibrator horn 33 to vibrate.

[0047] In the specific connection of the rear hanging component and the ear hook component, the rear hanging component is made by fixing the wire 15 to the elastic metal wire 13 and placing it in the mold. At the same time, the plug part 11 can be placed in the mold. Then, the elastic coating 14 is poured into the mold to cover the elastic metal wire 13 and the wire 15. The elastic coating 14 covers the fixed connection section 113. After cooling and shaping, it forms a whole. After the hanging component 1 is completed, the manufacturing process is completed.

[0048] Insert the connector 11 into the connector hole 211 on the movement housing 21, align the protrusion 114 with the slide groove 213, and after the connector 11 passes through the connector hole 211 and its protrusion 114 extends into the glue injection groove 212, rotate the rear hanging assembly 1 so that the connector 11 rotates at an angle, and after the protrusion 114 is misaligned with the slide groove 213, it is engaged with the outer edge of the connector hole 211. Then, glue is injected into the glue injection groove 212 to firmly connect the connector 11 to the connector hole 211.

[0049] The connector 11 is inserted into the connector hole 211 and rotated so that the protrusion 114 engages with the connector hole 211, forming a firm connection that can withstand strong tensile force. The connection structure has high strength and prevents the wire from coming off under strong tensile force. This improves assembly efficiency during mass production and ensures stable, reliable and controllable quality inspection.

[0050] In summary, this utility model has been manufactured into actual samples as described in the specification and figures, and has undergone multiple use tests. The results of these tests demonstrate that this utility model can achieve its intended purpose, and its practical value is undeniable. The embodiments described above are merely illustrative examples of this utility model and are not intended to limit it in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in this utility model without departing from its technical features shall also fall within the scope of this utility model's technical features.
