Description

Technical Field

[0001] This utility model relates to the field of external speaker headphone technology, and in particular to a speaker structure for an external speaker headphone. Background Technology

[0002] Headphones are a common audio playback device with wide applications and a large user base. Existing headphones can only receive audio signals and produce sound through internal speakers, meaning they can only play audio internally. While this can meet the audio listening needs of listeners, it cannot play audio externally or share audio across different areas, making their usage relatively limited.

[0003] The existing patent (CN 206533504U) discloses an earphone with a rotating external speaker structure, including a headband, a base plate fixing bracket, a base plate, an external speaker module, and an internal earphone module. The headband is arched and made of elastic material. Two internal earphone modules are respectively hinged to both ends of the headband and face each other. Two base plate fixing brackets are symmetrically installed inside the headband. Each base plate fixing bracket has a base plate installed on it. The base plate protrudes from the headband and has several contact points. The base plate also has a locking groove with a clearance opening for locking. This device can function as both internal and external speakers. The external speaker module is detachable, allowing for easy removal when not in use, facilitating general wear. It also features LED lights that illuminate and flash in sync with the music, enhancing the overall atmosphere during playback and allowing for quick switching between private and shared music enjoyment. However, in practical use, the speaker structure is difficult to adjust at different angles and is not easily protected from dust. Therefore, we have developed a new speaker structure for external headphones. Utility Model Content

[0004] The main objective of this invention is to provide a speaker structure for an external headphone, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figure 1-5 This utility model provides a technical solution:

[0027] A speaker structure for an external speaker headphone includes a fixed frame 1. Fixed blocks 2 are fixedly connected to the upper left and upper right sides of the outer surface of the fixed frame 1. Speaker components 3 are inserted and connected to the ends of the two fixed blocks 2 that do not contact the fixed frame 1. Earmuffs 4 are fixedly connected to the lower left and lower right sides of the fixed frame 1. A flexible rubber pad 5 is fixedly connected to the inner frame wall of the fixed frame 1.

[0028] In this embodiment, the speaker assembly 3 includes a support frame 31, a protective cover 32 is inserted and connected to the front end of the support frame 31, a flexible support rod 33 is fixedly connected to the left side of the outer surface of the support frame 31, a retaining frame 34 is fixedly connected to the inner frame wall of the support frame 31, a speaker body 35 is inserted and connected to the inner frame wall of the retaining frame 34, and the flexible support rod 33 is threadedly connected to the fixing block 2; the flexible support rod 33 includes a rod body 331, an insert rod 332 is fixedly connected to the right end of the rod body 331, a connector 333 is fixedly connected to the left end of the rod body 331, and the connector 333 is threadedly connected to the fixing block 2; the insert rod 332 is inserted and connected to the support frame 31.

[0029] The above scheme involves inserting the speaker body 35 into the frame 34 to position the speaker body 35, inserting the rod 332 on the flexible support rod 33 into the support frame 31, and inserting the connector 333 into the fixing block 2 to fix the speaker assembly 3 and the fixing frame 1 together. The rod 331 can support the support frame 31. The rod 331 is made of flexible and bendable material, which facilitates the angle rotation of the support frame 31, thereby facilitating the angle adjustment of the speaker body 35.

[0030] In this embodiment, the protective cover 32 includes a connecting screw tube 321, a dustproof net 322 is inserted and connected to the front end of the connecting screw tube 321, an outer dustproof cover 323 is inserted and connected to the front end of the dustproof net 322, the connecting screw tube 321 is inserted and connected to the support frame 31, and the connecting screw tube 321 is sleeved with the speaker body 35.

[0031] The above solution involves threading the connecting screw 321 to the support frame 31 to position the protective cover 32, and connecting the connecting screw 321 to the speaker body 35. The dustproof net 322 and the outer dustproof cover 323 work together to protect the speaker body 35 from dust during use.

[0032] It should be noted that this utility model is a speaker structure for an external speaker headphone. During use, the speaker body 35 is inserted and connected to the frame 34. The frame 34 provides a precise positioning space for the speaker body 35, allowing it to be accurately installed in a specific position, ensuring its stability during operation and preventing sound output from being affected by positional misalignment. The connecting screw tube 321 is threadedly connected to the support frame 31. By rotating the connecting screw tube 321, the threads gradually tighten it onto the support frame 31, thus determining the position of the protective cover 32. Simultaneously, the connecting screw tube 321 and the speaker... The speaker body 35 is fitted with a protective structure around it. The protective cover 32 not only prevents external objects from directly impacting the speaker body 35, but also provides a foundation for subsequent dustproof design. The dustproof mesh 322 and the outer dust cover 323 work together to protect the speaker body 35 from dust during use. The dustproof mesh 322 typically has fine mesh openings to block smaller dust particles from entering the speaker. The outer dust cover 323 further enhances the dustproof effect, blocking larger dust particles and debris from contacting the dustproof mesh 322 or directly entering the speaker body 35. This dual dustproof design significantly improves dust protection. The improved cleanliness of the speaker's working environment ensures stable performance of the speaker body 35 and extends its service life. The flexible support rod 332 is inserted and connected to the support frame 31, providing support to the frame. Simultaneously, the connector 333 is inserted and connected to the fixing block 2, firmly fixing the speaker assembly 3 to the fixing frame 1. This connection method allows the entire speaker structure to be stably installed in the corresponding position on the headphones. The rod 331 is made of a flexible, bendable material, which is crucial for adjusting the angle of the speaker body 35. When the angle of the speaker body 35 needs to be adjusted, the user can manually bend the rod 331. Due to the flexibility of the rod 331, it can bend freely within a certain range, thereby driving the support frame 31 to rotate. As the support frame 31 rotates, the angle of the speaker body 35 connected to the support frame 31 also changes. This design allows users to flexibly adjust the angle of the speaker according to their own usage habits and actual needs to obtain better sound reception. In summary, the speaker structure of this external headphone, through reasonable positioning, protection, connection, and angle adjustment design, ensures stable speaker operation and a good user experience.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
