Description

Technical Field

[0001] This utility model belongs to the field of bone conduction generators, and specifically relates to a bone conduction generator with detachable connectors. Background Technology

[0002] Bone conduction headphones transmit sound waves directly to the inner ear through the skull, without blocking the ear canal. Their advantages include open ears, avoiding discomfort from prolonged wear, and the ability to perceive ambient sound, enhancing outdoor safety. They are suitable for activities such as sports and cycling.

[0003] Existing bone conduction headphones can refer to a bone conduction headphone disclosed in Chinese Patent No. CN202410176414.3. The ear hook connects the housing and the shell, and the two housings are connected by a back hook. The shell houses the speaker, and the housing houses the circuit board and battery. When worn on the ear hook, the vibration of the shell is used for bone conduction output when the speaker is working.

[0004] The shortcomings of existing bone conduction headphones are that the ear hooks and back hooks are both slender structures with built-in wires, and the bone conduction headphones as a whole are not detachable. Therefore, when using or storing bone conduction headphones, the ear hooks and back hooks are easily bent, resulting in irreversible deformation or even breakage, which damages the bone conduction headphones. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a bone conduction generator in which a complete circuit structure consisting of a power supply battery, a circuit board, and a bone conduction speaker is housed within a housing, and the bone conduction generator is detachably mounted on a sound receiver via a connector that can be detachably connected to the housing.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0011] The present invention is further configured such that: the charging connector is disposed in the first assembly cavity, and the housing is provided with a plug-in opening for the charging cable to be inserted from the outside of the housing and connected to the charging connector.

[0012] The present invention is further configured such that: the connector is an ear hook, the ear hook is provided with a connecting part, and the connecting part is used to detachably engage with the charging connector.

[0013] The present invention is further configured such that: the connector is made of silicone, gel, TPE / TPV, or TR90; or, the connector is made of elastic metal and silicone / TPE coated; and / or, the connector is an integrally molded part or a coated part; and / or, the charging connector is provided with a plug cavity, a connecting piece is provided in the plug cavity, the connecting part is arranged in a ring shape, and the connecting part and the charging connector cooperate to allow the connecting part to be inserted into the plug cavity and the connecting piece to be inserted into the inner circumference of the connecting part.

[0014] The present invention is further configured such that: the connector adopts an ear hook, the ear hook is provided with a connecting part, and the connecting part is used to detachably engage with the housing.

[0047] To enable those skilled in the art to better understand this utility model and to more clearly define the scope of protection claimed by this utility model, the present utility model is described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present utility model, and the specific and direct descriptions of related structures are merely for the convenience of understanding the present utility model; the specific features do not necessarily or directly limit the scope of implementation of the present utility model. Conventional choices and substitutions made by those skilled in the art under the guidance of the present utility model should all be considered within the scope of protection claimed by this utility model.

[0048] Example 1:

[0049] like Figures 1-6 As shown, this utility model discloses a bone conduction generator with a detachable connector 5, comprising:

[0050] Housing 1, with a first assembly cavity 11 provided inside housing 1;

[0051] The power supply battery 2 is fixed in the first assembly cavity 11 by adhesive or clips.

[0052] Bone conduction speaker 3 is fixed in the first assembly cavity 11 by adhesive or snap-fit.

[0053] Circuit board 4 is fixed in the first assembly cavity 11 by adhesive or snap-fit. Power supply battery 2 and bone conduction speaker 3 are electrically connected to circuit board 4 by wires.

[0054] Connector 5 is detachably mounted on housing 1;

[0055] The connector 5 is used to detachably connect the sound receiver and the housing 1 to configure a bone conduction generator on the sound receiver.

[0056] In this embodiment, the connector 5 is an ear hook 51, and the sound receiver is the human body.

[0057] Therefore, 1. When the bone conduction generator is needed, the ear hook 51 and the housing 1 are assembled. The ear hook 51 is hung on the ear, and the housing 1 is pressed against the skull. The operation of the speaker drives the housing 1 to vibrate, which is transmitted to the skull. The skull directly transmits sound waves to the inner ear to complete the bone conduction vibration; 2. When the bone conduction generator is not needed, the ear hook 51 and the housing 1 are disassembled. The two are independent, so that if the easily bent ear hook 51 is damaged, it will not affect the housing 1 and the structure inside the housing 1. Only the ear hook 51 needs to be replaced; 3. The housing 1 houses the power supply battery 2, the bone conduction speaker 3, and the circuit board 4. The circuit structure of bone conduction vibration is assembled inside the housing 1, and the overall structure is simple and compact.

[0058] Additionally, a push-button switch 41 is provided on the circuit board 4, and a push-button opening 15 is provided on the housing 1. The two ends of the push-button opening 15 are through-holes to connect the first assembly cavity 11 and the outside of the housing 1. A push-button part 6 is slidably disposed at the push-button opening 15, and a silicone element 61 is disposed between the push-button switch 41 and the push-button part 6. Therefore, by pressing the push-button part 6 on the outside of the housing 1, the push-button part 6 moves towards the first assembly cavity 11, driving the silicone element 61 to deform and approach, thereby pressing the push-button switch 41, thus realizing circuit control.

[0059] Preferably, in this embodiment, the housing 1 is provided with a vibration end 12 and a control end 13 in opposite positions. The figure shows the vibration end 12 at the bottom and the control end 13 at the top. The bone conduction speaker 3 is connected to the vibration end 12, and the button part 6 is connected to the control end 13.

[0060] Therefore, the vibrating end 12 fits against the skull during use, while the control end 13 is located at the end of the housing 1 away from the skull, so that when the user presses the button part 6, the skull can provide support for the housing 1, making the pressing more stable.

[0061] In addition, this embodiment also includes a charging connector 7, which can be of type-c, lightning, etc. The charging connector 7 is fixed in the first assembly cavity 11 by adhesive bonding or snap-fit, and the charging connector 7 and the circuit board 4 are electrically connected by pin soldering. In addition, the housing 1 is provided with a plug-in opening 14, and the two ends of the plug-in opening 14 are through-hole to connect the first assembly cavity 11 and the outside of the housing 1.

[0062] Therefore, the user can charge the power supply battery 2 by inserting the charging cable into the plug-in opening 14 from the outside of the housing 1 and connecting the charging cable and the charging connector 7.

[0063] The control end 13 and the housing 1 are integrally formed, and the vibration end 12 is in the shape of a cover so that the first assembly cavity 11 can be opened when the vibration end 12 and the housing 1 are not assembled, so that the various parts that need to be assembled in the first assembly cavity 11 can be assembled. Then the vibration end 12 and the housing 1 are fixed by means of interference fit, glue bonding or other methods.

[0064] Specifically, the charging connector 7 has a plug cavity 71 on the side facing the plug opening 14, and a connecting piece 72 is provided in the plug cavity 71. The connecting part 511 is arranged in a ring shape. The connecting part 511 and the charging connector 7 cooperate to insert the connecting part 511 into the plug cavity 71 and to insert the connecting piece 72 into the inner circumference of the connecting part 511.

[0065] Preferably, one end of the ear hook 51 is integrally formed with a connecting part 511, which is used to detachably engage with the charging connector 7.

[0066] Therefore, 1. When the ear hook 51 and the housing 1 need to be assembled and used, the connecting part 511 is inserted into the outside of the housing 1 through the insertion opening 14 and cooperates with the charging connector 7; 2. By using the charging connector 7 as the carrier for assembling the ear hook 51 onto the housing 1, the housing 1 does not need to be equipped with a separate assembly structure, thus simplifying the structure of the housing 1; 3. The connecting part 511 also seals the insertion opening 14 and the charging connector 7 to provide dustproof and waterproof functions; 4. When the ear hook 51 needs to be assembled and used, it is not charged due to the sealing of the charging connector 7, and when the power supply battery 2 needs to be charged, the ear hook 51 is disassembled to expose the charging connector 7.

[0067] Preferably, the connector 5 is made of silicone material through one-piece injection molding. The soft silicone makes it more comfortable to wear and more completely seals the plug opening 14 and the charging port. One-piece injection molding makes production more convenient.

[0068] In other embodiments, connector 5 may also be made of gel, TPE / TPV, or TR90, or connector 5 may be made of elastic metal with silicone / TPE overmolding.

[0069] Specifically, the bone conduction loudspeaker 3 includes a housing 31, a vibrating plate 32, a voice coil structure 33, and a magnetic structure 34. The bottom of the housing 31 and the vibrating end 12 are glued together. A second assembly cavity 311 is provided inside the housing 31. The voice coil structure 33 is disposed in the second assembly cavity 311 and is fixedly disposed to the housing 31 by means of glue. The fixing part of the vibrating plate 32 is fixedly disposed to the housing 31 by means of glue, and the vibrating plate 32 is located in the second assembly cavity 311. The magnetic structure 34 is disposed in the second assembly cavity 311 and is fixedly disposed to the vibrating part of the vibrating plate 32 by means of glue.

[0070] Therefore, an audio signal is passed through the voice coil structure 33 so that the voice coil structure 33 acts on the solid magnetic structure 34 to realize the vibration of the vibrating plate 32, thereby transmitting the vibration to drive the vibration of the outer shell 31 and realizing vibration output.

[0071] Common solid magnetic structures 34 employ magnets or a combination of magnets and magnetic sheets.

[0072] The voice coil structure 33 is typically made of wire and is cylindrical, allowing the solid magnet structure 34 to be partially inserted into the inner circumference of the voice coil structure 33.

[0073] In other embodiments, an assembly structure may be separately provided on the housing 1, so that the ear hook 51 and the assembly structure can be detachably connected by means of sleeve, plug-in, snap-fit, etc.

[0074] Example 2:

[0075] like Figure 7 As shown, this utility model also discloses a bone conduction generator with a detachable connector 5. Its main structure is the same as that of Embodiment 1. The difference is that the connector 5 does not use an ear hook 51. Instead, the connector 5 uses a peelable adhesive piece 52. Specifically, the peelable adhesive piece 52 is a gel double-sided patch or a silicone double-sided patch.

[0076] Therefore, 1. When it is necessary to configure the connector 5 on the housing 1, one side of the peelable adhesive 52 is attached to the outer surface of the vibrating end 12, and the other side of the peelable adhesive 52 can be attached to the human skull or other sound receivers that can receive sound transmission and playback. The operation of the speaker drives the housing 1 and the peelable adhesive 52 to vibrate, which in turn vibrates the skull. The skull directly transmits sound waves to the inner ear to complete bone conduction vibration; 2. Since the peelable adhesive 52 is sheet-shaped and attached to the vibrating end 12, the volume of the combined bone conduction generator is basically equal to the volume of the housing 1, thus making the overall volume smaller. In addition, the structure inside the housing 1 will not be affected by the peelable adhesive 52. The peelable adhesive 52 is not removed after being attached to the housing 1 if the adhesive is strong enough. However, if the adhesive is not strong enough due to repeated removal and wearing, the peelable adhesive 52 should be removed from the housing 1 and replaced.

[0077] Example 3:

[0078] like Figure 8 As shown, this utility model also discloses a bone conduction generator with a detachable connector 5. Its main structure is the same as that of Embodiment 1, except that the connector 5 does not use an ear hook 51. Instead, the housing 1 is provided with a mating part 8 that can be detachably engaged with the connector 5. The connector 5 and the mating part 8 are combined to form a connecting assembly 9. Specifically, the connecting assembly 9 uses Velcro, magnetic tape, wearable nails, snap fasteners, fabric buckles, or magnetic buckles. The mating part 8 can be assembled to the housing 1 using a non-detachable method such as strong glue, or it can be assembled to the housing 1 using a detachable method such as double-sided tape. Similarly, the connector 5 can be assembled to the sound receiver using a non-detachable method such as strong glue. The sound receiver can be a pillow, sofa, or other suitable object. Alternatively, it can be assembled to the sound receiver using a detachable method such as adhesive with weaker bonding strength. The sound receiver can be a suitable object or a human body.

[0079] Therefore, by setting the connector 5 on the sound receiver and the mating part 8 on the shell 1, when it is necessary to assemble the shell 1 onto the sound receiver, the assembly is carried out by means of Velcro, magnetic attraction, snap-fit, etc., through the mating part 8 and the connector 5. The skull can contact the shell 1 or the sound receiver to receive vibration, and the skull directly transmits sound waves to the inner ear to complete bone conduction vibration.

[0080] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
