Abstract
Description
Technical Field
[0001] This invention relates to the field of headphone technology, and in particular to a clip-on headphone with replaceable batteries. Background Technology
[0002] With the booming development of the smart wearable industry, the variety of headphones is becoming increasingly rich, and users' demand for products that can be worn more conveniently and comfortably for extended periods is also growing stronger. Clip-on headphones are fixed to the ears by clamping them in place, allowing for long-term wear and providing good comfort.
[0003] Commercially available clip-on headphones typically consist of a clip-on unit, an in-ear unit, and a bridge. The bridge connects the clip-on and in-ear units. When worn, the clip-on and in-ear units are clamped together to the user's ear, with the in-ear unit facing the ear canal. The in-ear unit contains a speaker, and its housing has a sound outlet; the sound from the speaker is output through this outlet and then transmitted to the ear canal. The clip-on unit faces the back of the ear and usually includes a housing containing a battery and a PCBA circuit board. However, the housing of the clip-on unit in commercially available clip-on headphones is not removable, and neither is the battery inside. When the battery fails, it cannot be replaced, rendering the entire clip-on headphone unusable.
[0004] With technological advancements, technologies have gradually emerged that allow for the disassembly of the clip-on earphone housing. By disassembling the clip-on earphone housing, the battery inside can be replaced. However, the clip-on earphone housing in existing technologies has a relatively complex housing connection structure and battery mounting structure. These structures often feature complex snap-fit or screw connections. Disassembly requires specialized tools to separate the connection structure of the clip-on earphone housing and then the battery mounting structure before the battery can be removed and replaced. The battery replacement process is complex and often requires professional personnel to operate, making it difficult for ordinary users to perform. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to address the shortcomings of the prior art by providing an ear-clip earphone with a replaceable battery. This ear-clip earphone divides the clamping unit into two modules: a main body module and a battery module. The main body module and the battery module can be magnetically attached to each other or separated. Ordinary users can quickly and conveniently separate the main body module and the battery module, and replace the battery by replacing the battery module. When the main body module and the battery module are magnetically attached, the PCBA circuit board inside the main body module and the battery inside the battery module can be electrically connected through a first charging pin and a second charging pin, ensuring good power supply stability for the battery module.
[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: a replaceable battery ear clip earphone, comprising a clamping unit, an in-ear unit, and a bridge. The clamping unit includes a main body module and a battery module. The bridge connects the main body module of the clamping unit and the in-ear unit. The main body module includes a main body shell, a main body inner shell, a PCBA circuit board, a first charging pin, and a first magnet. The main body shell and the main body inner shell are mutually capped and connected, forming a first inner cavity. The PCBA circuit board is installed within the first inner cavity and is electrically connected to the first charging pin. One end of the first charging pin is mounted on the main body inner shell. The first magnet is installed on the inner side of the main body inner shell; the battery module includes a battery outer shell, a battery inner shell, a battery, a second charging pin, and a second magnet. The battery outer shell and the battery inner shell are connected to each other and form a second inner cavity. The battery is installed inside the second inner cavity. The PCBA circuit board is electrically connected to the second charging pin. One end of the second charging pin is installed on the battery inner shell. The second magnet is installed on the inner side of the main body inner shell. The main body inner shell and the battery inner shell can be attached to each other or separated from each other. When the main body inner shell and the battery inner shell are attached to each other, the first charging pin and the second charging pin are in abutting contact, and the first magnet and the second magnet are magnetically attracted to each other.
[0007] The beneficial effects of this invention are as follows: The clamping unit is divided into two modules: a main body module and a battery module. Under the magnetic attraction of the first and second magnets, the inner shell of the main body and the inner shell of the battery can adhere to each other, thus magnetically attaching the main body module and the battery module. When the user applies a pulling force to separate the main body module and the battery module, the magnetic attraction of the first and second magnets is overcome, allowing the main body module and the battery module to separate. Therefore, ordinary users can quickly and easily separate the main body module and the battery module, and replace the battery by replacing the battery module. In the packaging of this invention's ear-clip headphones, each ear-clip headphone is equipped with two battery modules, one of which serves as a spare. The battery module of this invention's ear-clip headphones only contains the battery module, associated wires, and a second charging pin. Replacing the battery module will not affect the functionality of the ear-clip headphones. When the main body module and the battery module are magnetically attached, the PCBA circuit board inside the main body module and the battery inside the battery module can be electrically connected through the first and second charging pins, ensuring good power supply stability for the battery module.
[0008] In the above technical solution, the outer surface of the main body shell is curved, and the outer surface of the battery shell is curved. When the main body inner shell and the battery inner shell are fitted together, the main body shell and the battery shell are aligned, and the outer surfaces of the main body shell and the battery shell transition naturally. This structure ensures that the main body shell and the battery shell have visual integrity after being aligned, ensuring that the outer surfaces of the main body shell and the battery shell appear seamless, and ensuring that the main body module and the battery module form a complete clamping unit when they are fitted together, resulting in a good visual effect.
[0009] In the above technical solution, there are two of each of the first and second charging pins. The first charging pin is a spring pin, and the second charging pin is a copper post. A wire connects the second charging pin to the battery. When the main module and the battery module are attached to each other, the first and second charging pins can make elastic contact with each other, ensuring good contact and excellent conductivity.
[0010] In the above technical solution, the inner shell of the main body has an inwardly recessed cavity in the middle, and the inner shell of the battery has an outwardly protruding protrusion in the middle. One end of the battery is installed inside the protrusion. The outer shape of the protrusion matches the inner shape of the cavity. When the inner shell of the main body and the inner shell of the battery are in contact with each other, the protrusion is inserted into the cavity. This structure has the following advantages: Firstly, when the protrusion is inserted into the cavity, it can make the inner shell of the main body and the inner shell of the battery form a plug-in positioning function, ensuring a stable connection and preventing the inner shell of the main body and the inner shell of the battery from shifting. Secondly, the space inside the protrusion can be used to install one end of the battery, which can increase the accommodating space of the second inner cavity, thereby increasing the size and capacity of the battery.
[0011] In the above technical solution, a first magnet groove is provided on the side of the bottom of the concave cavity near the first inner cavity, and the first magnet is installed in the first magnet groove; a second magnet groove is provided on the inner side of the top of the protrusion, and the second magnet is installed in the second magnet groove. The positions of the first magnet groove and the second magnet groove can ensure that the first magnet and the second magnet are firmly attracted to each other. When the protrusion is inserted into the concave cavity, the top of the protrusion and the bottom of the concave cavity can be attracted to each other, and the attraction is stable.
[0012] In the above technical solution, the main module further includes a third charging pin. One end of the third charging pin is electrically connected to the PCBA circuit board, and the other end of the third charging pin is mounted on the main body shell. There are two third charging pins, which enable the clip-on earphones to achieve electrical connection with the external charging case.
[0013] In the above technical solution, the main module further includes a microphone and a silicone cavity. The microphone is installed inside the silicone cavity, which has a sound passage hole. The main outer shell has a sound inlet hole. The microphone is electrically connected to the PCBA circuit board. The silicone cavity is installed inside the main outer shell, and the position of the sound passage hole in the silicone cavity corresponds to the position of the sound inlet hole in the main outer shell. Preferably, a microphone mesh is installed inside the sound inlet hole of the main outer shell, and a sponge is provided at the sound passage hole of the silicone cavity. This invention installs the microphone inside the silicone cavity, wraps the microphone, and provides sponge, allowing the microphone to be supported by soft silicone and suspended, completely filtering out noise and avoiding feedback problems caused by noise.
[0014] In the above technical solution, a speaker is installed inside the in-ear unit, and one end of the in-ear unit has a speaker sound outlet. The shape of the in-ear unit is adapted to the concha of the human ear. When wearing clip-on headphones, the speaker sound outlet can extend into the external auditory canal. When wearing clip-on headphones with replaceable batteries, the in-ear unit can be placed inside the concha of the human ear, and the speaker sound outlet can directly extend into the external auditory canal, significantly improving the sound pickup effect.
[0015] In the above technical solution, the bridge portion includes a silicone body, one end of which is connected to a first connecting plug, and the other end of which is connected to a second connecting plug. A metal wire and an electrical wire are installed inside the silicone body; one end of the metal wire is connected to the first connecting plug, and the other end is connected to the second connecting plug. The in-ear unit portion has a first connecting hole, and the main body shell of the main module has a second connecting hole. One end of the first connecting plug is inserted into the first connecting hole, and one end of the second connecting plug is inserted into the second connecting hole. One end of the electrical wire passes through the first connecting plug and is electrically connected to the speaker, and the other end of the electrical wire passes through the second connecting plug and is electrically connected to the PCBA circuit board. This invention can improve the flexibility of the outer side of the bridge portion through the silicone body and improve the clamping elasticity of the bridge portion through the metal wire.

[0025] The structural and working principles of the present invention will be further described in detail below with reference to the accompanying drawings.
[0026] like Figures 1-9 As shown, the present invention provides a replaceable battery ear clip-on earphone, including a clamping unit 1, an in-ear unit 3, and a bridge 4. The clamping unit 1 includes a main body module 10 and a battery module 20. The bridge 4 connects the main body module 10 and the in-ear unit 3 of the clamping unit 1. The main body module 10 includes a main body shell 11, a main body inner shell 12, a PCBA circuit board 13, a first charging pin 14, and a first magnet 15. The main body shell 11 and the main body inner shell 12 are mutually capped and connected, forming a first inner cavity 16. The PCBA circuit board 13 is installed within the first inner cavity 16 and is electrically connected to the first charging pin 14. One end of the first charging pin 14 is installed on the main body inner shell 12, and the first magnet 15 is installed on... The battery module 20 includes a battery outer shell 21, a battery inner shell 22, a battery 23, a second charging pin 24, and a second magnet 25. The battery outer shell 21 and the battery inner shell 22 are connected to each other and form a second inner cavity 26. The battery 23 is installed inside the second inner cavity 26 and is electrically connected to the second charging pin 24. One end of the second charging pin 24 is installed on the battery inner shell 22. The second magnet 25 is installed on the inner side of the main body inner shell 12. The main body inner shell 12 and the battery inner shell 22 can be attached to each other or separated from each other. When the main body inner shell 12 and the battery inner shell 22 are attached to each other, the first charging pin 14 and the second charging pin 24 abut against each other, and the first magnet 15 and the second magnet 25 are magnetically attracted to each other.
[0027] This invention divides the clamping unit 1 into two modules: a main body module 10 and a battery module 20. Under the magnetic attraction of the first magnet 15 and the second magnet 25, the inner shell 12 of the main body and the inner shell 22 of the battery can be attached to each other, thereby allowing the main body module 10 and the battery module 20 to be magnetically attached to each other. When the user applies a pulling force to separate the main body module 10 and the battery module 20, the magnetic attraction of the first magnet 15 and the second magnet 25 can be overcome, allowing the main body module 10 and the battery module 20 to be separated. Thus, ordinary users can quickly and easily separate the main body module 10 and the battery module 20, and replace the battery 23 by replacing the battery module 20. When packaging the ear clip earphone of this invention, each ear clip earphone is equipped with two battery modules 20, one of which is a spare battery module 20. The battery module 20 of the ear clip earphone of this invention only contains the battery module 20 and the associated wires and the second charging pin 24. After the user replaces the battery module 20, it will not affect the function of the ear clip earphone. When the main module 10 and the battery module 20 are magnetically attached to each other, the PCBA circuit board 13 inside the main module 10 and the battery 23 inside the battery module 20 can be electrically connected through the first charging pin 14 and the second charging pin 24, ensuring that the battery module 20 has good power supply stability.
[0028] like Figures 1-7 As shown, the outer surface of the main body shell 11 is curved, and the outer surface of the battery shell 21 is curved. When the main body inner shell 12 and the battery inner shell 22 are fitted together, the main body shell 11 and the battery shell 21 are aligned, and the outer surfaces of the main body shell 11 and the battery shell 21 transition naturally. This structure ensures that the main body shell 11 and the battery shell 21 have visual integrity after being aligned, ensuring that the outer surfaces of the main body shell 11 and the battery shell 21 appear seamless, and ensuring that the main body module 10 and the battery module 20 form a complete clamping unit 1 when they are fitted together, resulting in a good visual effect.
[0029] like Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, there are two of each of the first charging pin 14 and the second charging pin 24. The first charging pin 14 is a spring pin, and the second charging pin 24 is a copper post. A wire 27 connects the second charging pin 24 to the battery 23. When the main module 10 and the battery module 20 are in contact with each other, the first charging pin 14 and the second charging pin 24 can make elastic contact with each other, ensuring good contact and excellent conductivity.
[0030] like Figure 2 , Figure 4 and Figure 7 As shown, the inner shell 12 of the main body has an inwardly recessed cavity 121 in the middle, and the inner shell 22 of the battery has an outwardly protruding protrusion 221 in the middle. One end of the battery 23 is installed inside the protrusion 221. The protrusion 221 has a protrusion cavity for installing the battery 23, and the protrusion cavity is connected to the second inner cavity 26. The outer shape of the protrusion 221 matches the inner shape of the cavity 121. When the inner shell 12 of the main body and the inner shell 22 of the battery are in contact with each other, the protrusion 221 is inserted into the cavity 121. This structure has the following advantages: on the one hand, when the protrusion 221 is inserted into the cavity 121, it can make the inner shell 12 of the main body and the inner shell 22 form a plug-in positioning function, and the connection is stable, avoiding the problem of misalignment between the inner shell 12 of the main body and the inner shell 22 of the battery; on the other hand, the space inside the protrusion 221 can be used to install one end of the battery 23, which can increase the accommodating space of the second inner cavity 26, thereby increasing the size and capacity of the battery 23.
[0031] like Figure 6 As shown, a first magnet groove 122 is provided on the side of the bottom of the cavity 121 near the first inner cavity 16, and the first magnet 15 is installed in the first magnet groove 122; a second magnet groove 222 is provided on the inner side of the top of the protrusion 221, and the second magnet 25 is installed in the second magnet groove 222. The positions of the first magnet groove 122 and the second magnet groove 222 ensure that the first magnet 15 and the second magnet 25 are firmly attracted to each other. When the protrusion 221 is inserted into the cavity 121, the top of the protrusion 221 can be attracted to the bottom of the cavity 121, and the attraction is stable.
[0032] like Figure 1 and Figure 5 As shown, the main module 10 also includes a third charging pin 17. One end of the third charging pin 17 is electrically connected to the PCBA circuit board 13, and the other end of the third charging pin 17 is mounted on the main housing 11. There are two third charging pins 17, and the two third charging pins 17 enable the ear clip-on earphones to achieve electrical connection with the external charging case.
[0033] like Figures 1-7As shown, the main module 10 also includes a microphone 18 and a silicone cavity 181. The microphone 18 is installed inside the silicone cavity 181, which has a sound passage hole 182. The main housing 11 has a sound inlet hole 111. The microphone 18 is electrically connected to the PCBA circuit board 13. The silicone cavity 181 is installed inside the main housing 11, and the position of the sound passage hole 182 of the silicone cavity 181 corresponds to the position of the sound inlet hole 111 of the main housing 11. Preferably, a microphone mesh 112 is installed inside the sound inlet hole 111 of the main housing 11, and a sponge 113 is provided at the sound passage hole 182 of the silicone cavity 181. This invention installs the microphone 18 inside the silicone cavity 181, encloses the microphone 18, and provides the sponge 113, allowing the microphone 18 to be supported by soft silicone and suspended, completely filtering out noise and avoiding feedback problems caused by noise.
[0034] like Figures 1-3 As shown, a speaker (not shown) is installed inside the in-ear unit 3. One end of the in-ear unit 3 has a speaker outlet 31. The shape of the in-ear unit 3 is adapted to the concha of the human ear. When wearing clip-on headphones, the speaker outlet 31 can extend into the external auditory canal. When wearing clip-on headphones with replaceable batteries 23, the in-ear unit 3 can be placed inside the concha of the human ear, and the speaker outlet can directly extend into the external auditory canal, significantly improving the sound pickup effect.
[0035] like Figure 3 As shown, the bridge portion 4 includes a silicone body 41, one end of which is connected to a first connector 42, and the other end of which is connected to a second connector 43; a metal wire 44 and an electrical wire 45 are installed inside the silicone body 41, one end of the metal wire 44 is connected to the first connector 42, and the other end of the metal wire 44 is connected to the second connector 43; as shown... Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the in-ear unit 3 is provided with a first connection hole 32, and the main body shell 11 of the main body module 10 is provided with a second connection hole 19. One end of the first connection plug 42 is inserted into the first connection hole 32, and one end of the second connection plug 43 is inserted into the second connection hole 19. One end of the wire 45 passes through the first connection plug 42 and is electrically connected to the speaker, and the other end of the wire 45 passes through the second connection plug 43 and is electrically connected to the PCBA circuit board 13.
