Description

Technical Field

[0001] This invention relates to the field of headphone technology, and in particular to a headphone with replaceable battery and light-emitting module. Background Technology

[0002] Headphones are a common electronic device in daily life. They can be categorized by usage method into over-ear, in-ear, and earbud types. Over-ear headphones are widely popular due to their wider soundstage and lower risk of hearing damage from prolonged use. They can also be used as a fashion accessory. Over-ear headphones typically include wired and wireless models. Wireless headphones require rechargeable batteries, which are usually fixed inside the headphone's casing and difficult to replace. Furthermore, some existing over-ear headphones feature illuminated patterns on their casing, but these patterns are also not replaceable.

[0003] With the advancement of technology, some replaceable battery headphones have gradually emerged in the existing technology. These headphones usually have a battery cavity and a cover on the headphone housing. The battery is housed inside the battery cavity, and the cover is placed outside the battery compartment. When the battery needs to be replaced, the cover is opened to replace the battery. However, such replaceable battery headphones also have the following technical problems: (1) Only the battery can be replaced, but the battery module with a protective shell cannot be replaced. In the existing technology, rechargeable batteries are usually soft-pack aluminum shell batteries. These soft-pack aluminum shell batteries are easily deformed and damaged when they are hit or scratched by external objects. Replaceable battery headphones usually have more than two rechargeable batteries. For the spare battery that is not installed in the housing, since there is no protective shell outside the battery, it is easy to be deformed and damaged by external objects when it is hit or scratched; (2) When there is a light-emitting pattern on the headphone housing, such replaceable battery headphones cannot replace the light-emitting component with the pattern at the same time as replacing the battery. Summary of the Invention

[0004] The technical problem this invention aims to solve is to address the shortcomings of the prior art by providing a headset with a replaceable battery and light-emitting module. This headset allows for simultaneous replacement of both the battery and the patterned light-emitting component. The spare battery and light-emitting module are protected by the battery casing, preventing direct impact or scratches that could cause deformation or damage. The battery and light-emitting module are replaced by screwing into or out of the recessed cavity of the main body casing, allowing for quick and convenient replacement by ordinary users. The main body module of the headset and the battery and light-emitting module are electrically connected via a first and a second ejector pin assembly, ensuring good power supply stability for the battery and light-emitting module.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a replaceable battery and light-emitting module headset, comprising a first earphone part, a second earphone part, and a headband part, wherein both ends of the headband part are respectively connected to the first earphone part and the second earphone part, the first earphone part includes a main body module and a battery and a light-emitting module, the main body module includes a main body shell, and a speaker, a PCBA circuit board, and a first ejector pin assembly are installed inside the main body shell, the PCBA circuit board is electrically connected to the speaker and the first ejector pin assembly respectively, the main body shell has an inwardly recessed cavity, the cavity has an internal thread, and one end of the first ejector pin assembly extends into the cavity. Within the battery, the PCBA circuit board is electrically connected to the speaker and the first ejector pin assembly. The battery and light-emitting module include a battery housing with external threads. The battery housing can be screwed into or out of the recess. Inside the battery housing, a battery, a light-emitting element, and a second ejector pin assembly are installed. The battery and the light-emitting element are electrically connected to the second ejector pin assembly. One end of the second ejector pin assembly extends to one side of the battery housing. When the battery housing is screwed into the recess, the second ejector pin assembly and the first ejector pin assembly abut against each other. The other side of the battery housing has a light-transmitting pattern, and the light emitted by the light-emitting element can be directed toward the light-transmitting pattern.

[0006] The beneficial effects of the technical solution of the present invention are: (1) The present invention divides the first earphone into two modules: the main body module and the battery and light-emitting module. The main body module and the battery and light-emitting module can be combined or separated from each other. By replacing the battery and light-emitting module, the purpose of replacing the battery can be achieved. Moreover, the battery, light-emitting component and light-transmitting pattern are all integrated into the battery and light-emitting module. When replacing the battery and light-emitting module, the battery, light-emitting component and light-transmitting pattern can be replaced at the same time. When packaging the present invention's over-ear headphones, each over-ear headphone is equipped with at least two batteries and light-emitting modules. Different batteries and light-emitting modules have different light-transmitting patterns. For example, the light-transmitting pattern of one battery and light-emitting module is an animal cartoon pattern, and the light-transmitting pattern of the other battery and light-emitting module is a circular light-transmitting pattern, a star and moon light-transmitting pattern or a trademark light-transmitting pattern, etc. (2) Since the battery and light-emitting module of the present invention are provided with a battery shell, and the battery and light-emitting component are respectively installed inside the battery shell, the battery and light-emitting module can be protected by the battery shell, avoiding the problem of the battery being deformed and damaged by direct collision or scratch of external objects. (3) Since the main body shell of the present invention has an inwardly recessed cavity with an internal thread inside the cavity and an external thread on the battery shell, the battery shell can be screwed into the cavity or screwed out from the cavity to separate. Therefore, the battery and light-emitting module of the headset of the present invention can be replaced by screwing into or out of the cavity of the main body shell, so that ordinary users can replace them quickly and conveniently. (4) The main body module, the battery and the light-emitting module of the present invention can be electrically connected through the first pin assembly and the second pin assembly. The PCBA circuit board inside the main body module and the battery inside the battery and the light-emitting module can be electrically connected through the first pin assembly and the second pin assembly, ensuring that the battery and the light-emitting module have good power supply stability.

[0007] In the above technical solution, the main body shell includes a first shell, a second shell, and a recessed cavity. The first shell and the second shell are connected and overlap each other to form a first inner cavity. One side of the second shell has a mounting hole. The outer end of the recessed cavity is fixedly installed in the mounting hole, and the inner end of the recessed cavity extends into the first inner cavity. The recessed cavity is located within the recessed cavity. This structure makes the main body shell easier to injection mold and assemble, and provides good stability.

[0008] In the above technical solution, the cavity is a circular cavity, one end of the first ejector pin assembly is connected to the bottom of the cavity body, and the cavity body has the internal thread on its side. This invention uses a circular cavity, which facilitates the rotation of the battery casing within the cavity. By connecting one end of the first ejector pin assembly to the bottom of the cavity body, this invention allows the first and second ejector pin assemblies to achieve electrical connection after the battery casing is screwed into the cavity, and to separate when the battery casing is screwed out.

[0009] In the above technical solution, the headband is connected to one end of the first housing. One side of the first housing is provided with a speaker mounting slot and a circuit board mounting slot. The speaker is mounted within the speaker mounting slot, which has multiple speaker sound outlet holes. The PCBA circuit board is mounted within the circuit board mounting slot. Further, the outer side of the first housing is provided with control buttons, a USB Type-C port, and a microphone hole that mate with the PCBA circuit board. The first earphone also includes an earcup assembly, which is connected to the other side of the first housing. The sound emitted by the speaker can enter the earcup assembly through the speaker sound outlet holes.

[0010] In the above technical solution, the battery casing includes a screw-in housing and a cover. The screw-in housing and the cover are connected and overlap each other, forming a second inner cavity. The battery, the light-emitting element, and the second ejector assembly are installed within the second inner cavity. The shape of the screw-in housing is adapted to the shape of the cavity. One end of the second ejector assembly is connected to the bottom of the screw-in housing. The outer side wall of the screw-in housing is provided with the external thread, and the cover is provided with the light-transmitting pattern. This structure of the battery casing allows the screw-in housing to be better screwed into or out of the cavity of the main casing, while the cover is always exposed, allowing the light-transmitting pattern on the cover to be directly observed by the consumer, resulting in a better visual effect.

[0011] In the above technical solution, the outer side of the cover transitions naturally with the outer side of the main shell. This structure ensures that the main shell and the battery shell have visual integrity after being combined, and that the outer sides of the main shell and the battery shell appear seamlessly integrated, resulting in a good visual effect.

[0012] In the above technical solution, the first earpiece is equipped with at least two batteries and a light-emitting module. This facilitates battery replacement and the ability to change different light-transmitting patterns. Attached Figure Description

[0019] The structural and working principles of the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] like Figures 1-6 As shown, the present invention provides a headphone with replaceable battery and light-emitting module, including a first earphone part 100, a second earphone part 200, and a headband part 300. Both ends of the headband part 300 are connected to the first earphone part 100 and the second earphone part 200, respectively. The first earphone part 100 includes a main body module 1 and a battery and light-emitting module 2. The main body module 1 includes a main body shell 11. A speaker 12, a PCBA circuit board 13, and a first ejector pin assembly 14 are installed inside the main body shell 11. The PCBA circuit board 13 is electrically connected to the speaker 12 and the first ejector pin assembly 14, respectively. The main body shell 11 has an inwardly recessed cavity 114, and an internal thread 115 is provided within the cavity 114. One end of the first ejector pin assembly 14 extends into the cavity 114. The BA circuit board 13 is electrically connected to the speaker 12 and the first ejector assembly 14. The battery and light-emitting module 2 includes a battery housing 21 with external threads 213. The battery housing 21 can be screwed into or out of the recess 114. A battery 22, a light-emitting element 23, and a second ejector assembly 24 are installed inside the battery housing 21. The battery 22 and the light-emitting element 23 are electrically connected to the second ejector assembly 24. One end of the second ejector assembly 24 extends towards one side of the battery housing 21. When the battery housing 21 is screwed into the recess 114, the second ejector assembly 24 and the first ejector assembly 14 abut against each other. The other side of the battery housing 21 has a light-transmitting pattern 214, and the light emitted by the light-emitting element 23 can be directed towards the light-transmitting pattern 214. In this embodiment, the first ejector assembly 1 includes four spring ejectors, and the second ejector assembly 24 includes four copper pillars. The main body shell 11 is marked with a first "△" symbol, and the battery shell 21 is marked with a first "△" symbol. When the battery shell 21 is screwed into the recess 114, the second "△" symbol points to the first "△" symbol.

[0021] This invention divides the first earphone unit 100 into two modules: a main body module 1 and a battery and light-emitting module 2. The main body module 1 and the battery and light-emitting module 2 can be combined or separated. By replacing the battery and light-emitting module 2, the purpose of replacing the battery 22 can be achieved. The battery 22, the light-emitting element 23, and the light-transmitting pattern 214 are all integrated into the battery and light-emitting module 2. When replacing the battery and light-emitting module 2, the battery 22, the light-emitting element 23, and the light-transmitting pattern 214 can be replaced simultaneously. When packaging the headphones of this invention, each headphone is equipped with at least two batteries and light-emitting modules 2. Different batteries and light-emitting modules 2 have different light-transmitting patterns 214. For example, the light-transmitting pattern 214 of one battery and light-emitting module 2 is an animal cartoon graphic, while the light-transmitting pattern 214 of the other battery and light-emitting module 2 is a circular light-transmitting pattern 214, a star and moon light-transmitting pattern 214, or a trademark light-transmitting pattern 214, etc. When the light emitted by the light-emitting element 23 shines on the light-transmitting pattern 214, the light-transmitting pattern 214 will light up. The battery and light-emitting module 2 of the present invention are protected by the battery casing 21, preventing the battery 22 from being deformed or damaged by direct impact or scratches from external objects. The battery and light-emitting module 2 of the present invention can be replaced by screwing into or out of the cavity 114 of the main body casing 11, which allows ordinary users to replace them quickly and conveniently. The main body module 1 and the battery and light-emitting module 2 of the present invention can be electrically connected through the first ejector pin assembly 14 and the second ejector pin assembly 24. The PCBA circuit board 13 inside the main body module 1 and the battery 22 inside the battery and light-emitting module 2 can be electrically connected through the first ejector pin assembly 14 and the second ejector pin assembly 24, ensuring that the battery and light-emitting module 2 have good power supply stability.

[0022] like Figures 1-4 As shown, the main body shell 11 includes a first shell 111, a second shell 112, and a cavity 113. The first shell 111 and the second shell 112 are connected to each other and form a first inner cavity 116. One side of the second shell 112 has a mounting hole 1121. The outer end of the cavity 113 is fixedly installed in the mounting hole 1121, and the inner end of the cavity 113 extends into the first inner cavity 116. The cavity 114 is located within the cavity 113. The first shell 111, the second shell 112, and the cavity 113 are separately injection molded and then assembled together. This structure makes the injection molding and assembly of the main body shell 11 easier and provides good stability.

[0023] like Figures 1-4As shown, the cavity 114 is a circular cavity. One end of the first ejector assembly 14 is connected to the bottom of the cavity body 113. The cavity body 113 has the internal thread 115 on its side. The present invention uses a circular cavity 114 to facilitate the rotation of the battery casing 21 within the cavity 114. By connecting one end of the first ejector assembly 14 to the bottom of the cavity body 113, the present invention enables the first ejector assembly 14 and the second ejector assembly 24 to achieve electrical connection after the battery casing 21 is screwed into the cavity 114, and to separate from each other when the battery casing 21 is screwed out.

[0024] like Figures 1-4 As shown, the headband 300 is connected to one end of the first housing 111. One side of the first housing 111 has a speaker mounting slot 1111 and a circuit board mounting slot 1112. The speaker 12 is mounted within the speaker mounting slot 1111, which has multiple speaker sound outlet holes 1113. The PCBA circuit board 13 is mounted within the circuit board mounting slot 1112. Further, the outer side of the first housing 111 has control buttons 1114, a USB Type-C port 115, and a microphone hole 1116 that cooperate with the PCBA circuit board 13. The first earphone part 100 also includes an earcup assembly 13, which is connected to the other side of the first housing 111. The sound emitted by the speaker 12 can enter the earcup assembly 13 through the speaker sound outlet holes 1113.

[0025] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the battery casing 21 includes a screw-in housing 211 and a cover 212. The screw-in housing 211 and the cover 212 are connected to each other and form a second inner cavity 215. The battery 22, the light-emitting element 23, and the second ejector assembly 24 are installed within the second inner cavity 215. The shape of the screw-in housing 211 is adapted to the shape of the cavity 114. One end of the second ejector assembly 24 is connected to the bottom of the screw-in housing 211. The outer side wall of the screw-in housing 211 is provided with the external thread 213, and the cover 212 is provided with the light-transmitting pattern 214. This structure of the battery casing 21 allows the screw-in housing 211 to be better screwed into or out of the cavity 114 of the main casing 11, while the cover 212 is always exposed, allowing the light-transmitting pattern 214 on the cover 212 to be directly observed by the consumer, resulting in a better visual effect.

[0026] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the outer side of the cover 212 transitions naturally with the outer side of the main shell 11. This structure ensures that the main shell 11 and the battery shell 21 have visual integrity after being combined, and that the outer sides of the main shell 11 and the battery shell 21 appear seamlessly integrated, resulting in a good visual effect.

[0027] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the first earphone part 100 is equipped with at least two batteries and light-emitting modules 2, which facilitates the replacement of batteries 22 and different light-transmitting patterns 214. Each battery and light-emitting module 2 adopts a different pattern of light-transmitting pattern 214, such as animal cartoon pattern, circular light-transmitting pattern 214, star and moon light-transmitting pattern 214 or trademark light-transmitting pattern 214, etc.
