[0046] The embodiments of the present application disclose an interface speaker structure.

[0047] Please refer to Figure 1 , an embodiment of an interface speaker structure provided in the embodiments of the present application includes:

[0048] An interface component 1 and a speaker component 2.

[0049] The interface component 1 includes a USB hole 12 and a USB female socket 11. The USB female socket 11 is a socket of a USB connector, which can be specifically divided into a USB Type-A female socket, a USB Type-B female socket, a Micro USB female socket 11, a Mini USB female socket 11, and a USB Type-C female socket. In the present application, it is preferably designed as a USB Type-C female socket. Those skilled in the art can make changes according to actual needs without limitation.

[0050] The insertion end of the USB female socket 11 extends into the USB hole 12, and a clearance hole 13 is formed between the insertion end and the USB hole 12. Specifically, the size of the USB hole 12 is larger than that of the insertion end of the USB female socket 11, and an annular clearance hole 13 is formed between the insertion end of the USB female socket 11. Of course, it can also be several clearance holes 13 (non - continuous annular clearance holes 13), and there is no specific limit.

[0051] The speaker assembly 2 includes a transmission channel 21, a sound inlet hole 22, and a speaker 23.

[0052] The sounding end of the speaker 23 communicates with the sound inlet hole 22, and the sound inlet hole 22 communicates with the clearance hole 13 through the transmission channel 21.

[0053] The interface speaker structure designed in this application has the following beneficial effects:

[0054] 1. Innovatively, the clearance hole 13 formed between the USB female socket 11 and the USB hole 12 is used as the speaker hole, completely abandoning the traditional method of separately designing speaker holes on the outer shell. Through this ingenious design, the USB hole 12 not only retains its original charging function but also is additionally endowed with the function of emitting sound, thus realizing dual purposes. This design not only effectively reduces the manufacturing cost of the charging box but also greatly simplifies the structural complexity of the product, making the product more concise and efficient.

[0055] 2. The bottom of the traditional charging box is provided with a plurality of speaker holes and limiting grooves arranged in a porous manner. In order to fit and seal with the dustproof net 27, the size of the limiting groove is the same as that of the dustproof net 27, and the speaker hole at the bottom of the limiting groove is in direct contact with the outside, which increases the risk that external dust and liquid enter the inside of the charging box through the speaker hole, resulting in performance degradation. To solve this problem, in the design of this application, the transmission channel 21 is carefully constructed to ensure that the contact path between the speaker 23 and the external environment is extended. This design, combined with the clearance hole 13 in the USB hole 12, significantly improves the dustproof and waterproof performance of the charging box. Through such improvement, the charging box can better resist the invasion of the external environment, thereby effectively extending the service life of the product and ensuring that users can enjoy a more lasting use experience.

[0056] The above is the first embodiment of an interface speaker structure provided by this application. The following is the second embodiment of an interface speaker structure provided by this application. For details, please refer to Figure 1 。

[0057] Based on the solution of the first embodiment above:

[0058] Further, a positioning flange 26 for the speaker 23 to be snapped into is provided on the outer ring of the sound inlet hole 22; there is a support surface between the inner wall of the positioning flange 26 and the inner wall of the sound inlet hole 22, which is used to support the speaker 23 snapped into the positioning flange 26. This design makes the installation of the speaker 23 more stable and not easy to loosen, ensuring the stability and durability of the sound effect. At the same time, the setting of the positioning flange 26 and the support surface also simplifies the installation process of the speaker 23 and improves the production efficiency.

[0059] Further, a sealing structure 25 arranged around the sound inlet hole 22 is provided between the speaker 23 and the support surface. This design further enhances the sealing performance of the speaker 23, effectively preventing dust and moisture from seeping in through the gap between the speaker 23 and the support surface, thereby further improving the dust and water resistance of the charging case. At the same time, the use of the sealing structure 25 also improves the acoustic performance of the speaker 23, ensuring clear and pure sound quality.

[0060] The sealing structure 25 can be realized by ultrasonic welding, dispensing, silicone, back glue, etc., and there is no specific limitation.

[0061] Further, a dust-proof net 27 is covered on the sound-emitting end of the speaker 23.

[0062] The setting of the dust-proof net 27 can effectively block external dust and impurities from entering the inside of the speaker 23, protect the speaker 23 from damage, and at the same time ensure clear and pure sound quality. In addition, the design of the dust-proof net 27 is also easy to disassemble and clean, facilitating users' daily maintenance and prolonging the service life of the product.

[0063] Further, at least part of the channel section of the transmission channel 21 is in a meandering and zigzag shape.

[0064] This design not only increases the path length of sound transmission, improves the dust and water resistance effect, but also enables the sound to be better diffused and buffered during transmission, thereby improving the expressiveness of the sound quality. At the same time, the meandering and zigzag channel section also increases the damping of the sound during transmission, reduces sound reflection and resonance, and further improves the purity and clarity of the sound quality.

[0065] Further, a plurality of partition plates 24 are provided in the transmission channel 21; the plurality of partition plates 24 are arranged at intervals in sequence and are staggered up and down to form a meandering and zigzag channel section. The up-and-down staggered design of the partition plates 24 can not only form the required meandering and zigzag channel section, but also increase the rigidity of the transmission channel 21 and improve the overall structural stability.

[0066] The audio transmission process of the interface sound amplification structure designed in this application is as follows:

[0067] Speaker 23 -> Dust-proof net 27 -> Transmission channel 21 -> Gap hole 13.

[0068] As Figure 1 and Figure 2 shown, the present application also discloses a charging case, including a charging case body and an interface speaker structure; the interface speaker structure is arranged at the bottom inside the lower case 3 of the charging case body.

[0069] The charging case body is a conventional structural design, including an upper case, a lower case 3 hinged to the upper case. An upper inner lining is arranged in the upper case, and a lower inner lining 31, a main board 32, etc. are arranged in the lower case 3, which will not be elaborated herein.

[0070] Further, a main side surround 33 is provided at the bottom inside the lower case 3, and a cover plate 34 is hermetically installed on the top of the main side surround 33; a transmission channel 21 of the interface speaker structure is formed between the cover plate 34 and the main side surround 33. The cover plate 34 and the main side surround 33 can be hermetically connected by ultrasonic welding, dispensing, silica gel, back glue, etc., and no specific limitation is made.

[0071] The USB hole 12 of the interface speaker structure is opened at the bottom of the lower case 3 at a position inside the main side surround 33; the sound inlet hole 22 of the interface speaker structure is opened on the cover plate 34.

[0072] The cover plate 34 is also provided with an avoidance hole 35; a partial structure of the main board 32 fixed in the lower inner lining 31 of the lower case 3 extends into the transmission channel 21 through the avoidance hole 35 and is connected to the USB female socket 11 of the interface speaker structure; the part of the main board 32 passing through the avoidance hole 35 and the avoidance hole 35 can be hermetically connected by ultrasonic welding, dispensing, silica gel, back glue, etc., and no specific limitation is made.

[0073] The speaker 23 of the interface speaker structure is fixed on the cover plate 34 (specifically, it can be hermetically fixed on the cover plate 34 by ultrasonic welding, dispensing, silica gel, back glue, etc.) and is communicatively connected to the main board 32.

[0074] Through the above structural design, the integration degree of the interface speaker structure and the charging case body is higher, and the overall structure is more compact, which not only meets the user's demand for the thin and light charging case, but also ensures the high-quality output of the sound effect.

[0075] Further, the avoidance hole 35 and the USB hole 12 are arranged opposite to the main board 32, which is conducive to the part connected to the main board 32 extending into the transmission channel 21.

[0076] A positioning side surround 14 is provided on the outer ring of the USB hole 12 at the bottom inside the lower case 3; a positioning cavity for accommodating the USB female socket 11 is formed between the positioning side surround 14 and the cover plate 34; a communication port 15 is provided on the positioning side surround 14.

[0077] The design of the positioning cavity provides a stable installation space for the USB female socket 11, ensuring the accuracy and stability of the USB female socket 11 during installation. The setting of the communication port 15 facilitates the smooth transmission of sound from the communication port 15 through the gap hole 13.

[0078] This application also discloses a headphone device, including a headphone body and a charging case; a headphone receiving slot is provided in the charging case for receiving the headphone body and charging the headphone body.

[0079] The above provides a detailed introduction to an interface sound amplification structure, a charging case and a headphone device provided by this application. For those of ordinary skill in the art, according to the idea of the embodiments of this application, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to this application.
