Description

Technical Field

[0001] This utility model relates to the field of Bluetooth headset technology, and in particular to a clip-on Bluetooth headset. Background Technology

[0002] The clip-on earphones feature a clip-on design that securely holds the earlobe, preventing them from easily falling off. Compared to traditional ear-hook earphones, they are smaller, making them easier to store and carry. The clip-on design also provides better stability, preventing them from falling off even during vigorous activity. Furthermore, the increasing demand from consumers for comfort, stability, and sound quality in Bluetooth earphones has driven innovation in earphone design.

[0003] Chinese Patent Publication No. CN119233146A discloses an ear-clip Bluetooth headset, including a first clamping part and a second clamping part. The first clamping part contains a main board, and a clamping space is formed between the second clamping part and the first clamping part. The second clamping part is rotatably connected to the first clamping part via a rotating assembly. The clamping space is adjusted by relative rotation between the second and first clamping parts. An antenna circuit and an antenna feed point connected to the antenna circuit are arranged on the main board. The rotating assembly is electrically connected to the antenna circuit through the antenna feed point. Therefore, the ear-clip Bluetooth headset has the following problems:

[0004] The earphone shell and antenna are easily affected by external factors, which can interfere with the transmission of electrical signals from the speaker in the earphone and the electrical signals in the electronic components.

[0005] The limited internal space of Bluetooth headsets means that the sound-producing device inside the headset does not have enough space to produce sound and is easily affected by surrounding components. Utility Model Content

[0006] Therefore, this utility model provides an ear-clamping Bluetooth headset to overcome the problems in the prior art where the earphone shell and antenna easily interfere with electrical signals, and the sound-emitting device does not have enough space to emit sound.

[0007] To achieve the above objectives, this utility model provides a clip-on Bluetooth headset, comprising:

[0008] The ear cap is spherical, and the spherical outer shell of the ear cap is composed of a first front shell and a first rear shell connected together. The internal components of the ear cap include a main board, electrical components, a rubber base and a battery.

[0009] The earplug is spherical, and the spherical outer shell of the earplug is composed of a second front shell and a second rear shell connected together. The internal components of the earplug include a sub-plate, connecting threads, a connecting plate, a sound-generating device, and a support device.

[0010] A connecting antenna is disposed between the ear cap and the earplug. The connecting antenna has an arc-shaped structure and a sound guide groove is provided inside the connecting antenna. A sound guide tube is fixedly connected inside the sound guide groove. A first connecting block is provided on one side of the connecting antenna and a second connecting block is provided on the other side of the connecting antenna.

[0011] The first connecting block has an integrally formed limiting installation disc below it, and the second connecting block has an integrally formed supporting connecting base plate below it.

[0012] The connector includes a first connector and a second connector. The first connector is connected to the first connector block, and the second connector is connected to the second connector block. The connector is provided with a connecting groove for engaging and fixing the first connector block and the second connector block.

[0013] Furthermore, the first front housing is connected to the first connecting seat, and the first rear housing is connected to the first connecting block;

[0014] The second front housing is located below the second rear housing and is snapped into the second rear housing. The second rear housing and the second connecting seat are connected to the second connecting block.

[0015] Furthermore, the top of the motherboard is connected to the first connector, one side of the motherboard is connected to the first connector, some electrical components and the rubber seat, and the other side of the motherboard is connected to the limiting mounting disc and other electrical components.

[0016] Furthermore, the supporting connecting base plate is attached to the lower part of the second connecting seat, and includes two protruding limiting posts and a hollow connecting post with internal threads.

[0017] The connecting thread secures the sub-plate to the bottom of the second connecting seat by screwing it into the connecting post through a round hole passing through the sub-plate.

[0018] Furthermore, the sub-plate is connected to the connecting plate, and the connecting plate has a U-shaped structure and is located below the sub-plate.

[0019] Furthermore, the sound-generating device is located in the middle of the connecting plate, and it is connected to the sub-plate through the connecting plate;

[0020] The support device is located at the bottom of the connecting plate and is connected to the second front housing.

[0021] Furthermore, the limiting mounting disc is connected to the motherboard through four through posts that pass through the motherboard, and the limiting mounting disc is also provided with elastic clips for fixing the battery;

[0022] Two elastic clamping plates are arranged on both sides of the battery. The battery is connected to the main board through the elastic clamping plates and is fixed on one side of the limit mounting disc by elastic clamping blocks.

[0023] Further, a positioning groove is provided at the bottom of the limit mounting disc, and the positioning groove can limit the relative position of the limit mounting disc relative to the main board.

[0024] Further, the rubber seat is arranged on the side of the main board close to the first front housing.

[0025] Further, a sound hole is provided at the bottom of the second front housing.

[0026] Compared with the prior art, the beneficial effects of the present utility model are as follows: for the antenna connection structure, the sound guide tube is arranged inside the connecting antenna, and multiple connection points are provided, which can prevent interference with the electrical signals of the generating device in the input earplug and increase the stability of the signal transmission between the ear cap and the earplug.

[0027] Further, the rubber seat can reduce the vibration degree generated when the first front housing is contacted by an external force, and avoid interfering with the transmission process of electrical signals in the electrical components by the first front housing.

[0028] Further, the device isolates the main board and electrical components from the battery by setting the limit mounting disc. The main board and the battery are fixed by the elastic clamping blocks and through columns arranged on the limit mounting disc, which increases the stability and firmness of the components inside the ear cap. The elastic clamping blocks of the battery tightly combine the main board, the limit mounting disc and the battery, reduce the gap between the three to thereby reduce the occupied internal volume, increase the contact distance between the ear cap housing and the internal components, and further increase the stability of the components inside the ear cap.

[0029] Further, during the process of screwing the connecting thread through the round hole of the auxiliary board and screwing it with the connecting column, the auxiliary board can be positioned and fixed relative to the connecting column of the second connecting seat through the limit column, reducing the assembly difficulty between the internal components of the earphone. And the stability of the connection between the auxiliary board and the support connecting bottom plate is increased by the screwed connecting thread and connecting column, thereby tightly and firmly combining the internal components of the earplug with the connecting antenna.

[0030] Further, the connecting plate is approximately in the shape of a reversed "J". The connecting plate is connected to the generating device and the internal components at the middle and bottom of the connecting plate respectively, which can adopt a smaller volume of the connecting structure while ensuring the connection stability, and maximize the cavity volume of the internal cavity structure of the earplug on the premise of a smaller earplug volume, increase the bass quality and sound loudness of the sound generating device, and improve the user experience when using the Bluetooth earphone.

[0031] Furthermore, the sound-generating device is the core component of audio output, and its sound quality directly affects the user's listening experience. By placing the sound-generating device in the middle of the connecting plate, the cavity volume around the sound-generating device is increased, the contact area between the various components in the earphone and the sound-generating device is reduced, and the amount of medium that can transmit vibrations to the area around the sound-generating device after being affected by external conditions is reduced, thereby avoiding interference of vibrations with the output sound quality of the sound-generating device.

[0042] This utility model provides a clip-on Bluetooth headset, comprising:

[0043] A connecting antenna 3 is used to connect the ear cap 1 and the earplug 2. The connecting antenna 3 has an arc-shaped structure. A sound guide groove 35 is opened inside the connecting antenna 3. A sound guide tube 36 is fixedly connected inside the sound guide groove 35. A first connecting block 31 is provided on one side of the connecting antenna 3, and a second connecting block 32 is provided on the other side of the connecting antenna 3.

[0044] The first connecting block 31 has an integrally formed limit mounting disc 33 below it, the second connecting block 32 has a connecting hole, and the second connecting block 32 has an integrally formed support connecting base plate 34 below it.

[0045] Specifically, the antenna connection structure, with the sound guide tube 36 set inside the connecting antenna 3 and multiple connection points, can eliminate interference with the electrical signal of the device in the input earplug 2 and increase the stability of signal transmission between the ear cap 1 and the earplug 2.

[0046] The connecting seat includes a first connecting seat 41 and a second connecting seat 42. The first connecting seat 41 is connected to the first connecting block 31, and the second connecting seat 42 is connected to the second connecting block 32. The connecting seat is provided with a connecting groove for snapping and fixing the first connecting block 31 and the second connecting block 32.

[0047] The bottom of the limiting mounting disc 33 is provided with a positioning groove 332, which can limit the relative position of the limiting mounting disc 33 relative to the motherboard 14.

[0048] The supporting connecting base plate 34 is attached to the lower part of the second connecting seat 42, and includes two protruding limiting posts 321 and a hollow connecting post 341 with internal threads.

[0049] Ear cap 1 is spherical. The spherical outer shell of ear cap 1 is composed of a first front shell 11 and a first rear shell 12 connected together. The first front shell 11 is connected to the first connecting seat 41, and the first rear shell 12 is connected to the first connecting block 31.

[0050] Earplug 2 is spherical. The spherical outer shell of the earplug 2 is composed of a second front shell 21 and a second rear shell 22 connected together. The second front shell 21 is located below the second rear shell 22 and is snapped into the second rear shell 22. The second rear shell 22 is connected to the second connecting seat 42 and the second connecting block 32.

[0051] The bottom of the second front housing 21 is provided with a speaker hole 23;

[0052] In this embodiment, the ear cap 1 is larger than the earplug 2. When the user wears the Bluetooth headset, the earplug 2 is placed inside the auricle, the ear cap 1 is placed outside the auricle, and the connecting antenna 3 is clamped on the edge of the auricle.

[0053] The internal components of the ear cap 1 include a main board 14, electrical components, a rubber base 15, and a battery 13. The main board 14 is made of PCB material.

[0054] The top of the main board 14 is connected to the first connector 41. One side of the main board 14 is connected to the first connector 41, some electrical components and the rubber seat 15. The other side of the main board 14 is connected to the limiting mounting disc 33 and other electrical components.

[0055] The rubber seat 15 is disposed on the side of the main board 14 near the first front housing 11;

[0056] Specifically, the rubber seat 15 can reduce the degree of vibration when the first front housing 11 is contacted by an external force, and prevent the first front housing 11 from interfering with the transmission process of electrical signals in electrical components.

[0057] The limiting mounting disc 33 is connected to the main board 14 through four through posts 333 that pass through the main board 14. The limiting mounting disc 33 is also provided with an elastic locking block 331 for fixing the battery 13.

[0058] Two elastic clamping plates 131 are provided on both sides of the battery 13. The battery 13 is connected to the main board 14 through the elastic clamping plates 131 and is fixed to one side of the limiting mounting disk 33 by the elastic clamping block 331.

[0059] Specifically, this device isolates the main board 14 and electrical components from the battery 13 by setting a limiting mounting disc 33. The main board 14 and battery 13 are fixed by the elastic locking block 331 and the through post 333 set on the limiting mounting disc 33, which increases the stability and firmness of the internal components of the ear cap 1. The elastic locking block 331 of the battery 13 tightly combines the main board 14, the limiting mounting disc 33 and the battery 13 together, reducing the gap between the three and thus reducing the internal volume occupied, increasing the contact distance between the ear cap 1 shell and the internal components, and further increasing the stability of the internal components of the ear cap 1.

[0060] The internal components of the earplug 2 include a sub-plate 24, a connecting thread 25, a connecting plate 26, a sound-generating device 27, and a support device 28. The connecting thread 25 fixes the sub-plate 24 to the bottom of the second connecting seat 42 by screwing it to the connecting post 341 through a round hole passing through the sub-plate 24.

[0061] Specifically, during the process of screwing the connecting thread 25 through the round hole of the sub-plate 24 and the connecting post 341, the sub-plate 24 can be positioned and fixed relative to the connecting post 341 of the second connecting seat 42 by the limiting post 321, which reduces the assembly difficulty between the internal components of the earphone. Furthermore, the connection between the sub-plate 24 and the supporting connecting base plate 34 is increased by screwing the connecting thread 25 and the connecting post 341, thereby tightly and firmly combining the internal components of the earbud 2 with the connecting antenna 3.

[0062] The sub-board 24 is made of PCB material and is connected to the connecting board 26.

[0063] The connecting plate 26 has a U-shaped structure and is located below the sub-plate 24. It is used to connect the internal components of the earplug 2 to the sub-plate 24.

[0064] Specifically, the connecting plate 26 is approximately in the shape of the Chinese character 'ji'. It is connected to the generating device and the internal components at the middle part and the bottom part of the connecting plate 26 respectively. On the basis of ensuring the connection stability, it can adopt a smaller volume of the connecting structure, and retain the cavity volume of the internal cavity structure of the earplug 2 to the greatest extent under the premise that the volume of the earplug 2 is small, increasing the bass quality and sound loudness of the sound generating device 27, and improving the user experience when using the Bluetooth headset.

[0065] The sound generating device 27 is located in the middle part of the connecting plate 26, and is connected to the auxiliary plate 24 through the connecting plate 26, and is used for converting an electrical signal into sound for output.

[0066] The supporting device 28 is located at the bottom of the connecting plate 26 and is connected to the second front housing 21, and plays a supporting role for the connecting plate 26.

[0067] Specifically, at the same time, the sound generating device 27 is the core component of audio output, and its sound quality performance directly affects the user's auditory experience. By arranging the sound generating device 27 in the middle part of the connecting plate 26, the cavity volume around the generating device is increased, the contact area between each component in the earplug 2 and the sound generating device 27 is reduced, and the number of media that can transmit vibration to the periphery of the generating device after being affected by external conditions is reduced, thereby avoiding the interference of vibration on the output sound quality of the sound generating device 27.

[0068] During the working process, when the user wears the Bluetooth headset, the earplug 2 is placed inside the auricle, the ear cap 1 is placed outside the auricle, and the connecting antenna 3 is clamped on the edge of the auricle; during the working process, the battery 13 in the ear cap 1 provides power for the Bluetooth headset, the Bluetooth headset receives an electrical signal through the electrical components in the ear cap 1, and transmits the electrical signal to the earplug 2 of the Bluetooth headset through the sound guiding tube 36 arranged in the internal sound guiding groove 35 of the connecting antenna 3. The electrical signal in the earplug 2 is converted into sound for output through the sound generating device, and the output sound is transmitted to the user's ear through the sound emitting hole 23.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.

[0070] The above are only the preferred embodiments of the present invention and are not used to limit the present invention; for those skilled in the art, the present invention can have various changes and modifications.
