[0023] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0024] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0026] Reference Figures 1-6 As shown, according to one embodiment of this application, an external module 1 is provided. The external module 1 is applied to a head-mounted device. The external module 1 includes a housing 10 and a speaker module 13. The housing 10 has a receiving space. The speaker module 13 is disposed in the receiving space and located at the end of the housing 10. For example, the external module 1 also includes a camera module 12, which is disposed at one end of the housing 10 and the speaker module 13 is disposed at the other end of the housing 10. The speaker module 13 includes a speaker housing 131 and a speaker unit 132. The speaker unit 132 is disposed inside the speaker housing 131. The speaker housing 131 has a connecting boss 1301, which is used to snap-fit ​​with the outer shell 10.

[0027] In the external module 1 provided in this application embodiment, by providing a housing 10 with accommodating space and housing a speaker module 13 located at the end therein, components such as the speaker module can be independently externalized from the head-mounted device body. This arrangement avoids directly integrating audio devices onto the head-mounted device body, thereby effectively solving the problem of poor audio quality caused by the space limitations of the head-mounted device body, and helping to improve the sound quality performance of the speaker module and the overall performance of the head-mounted device.

[0028] The speaker module 13 includes a speaker housing 131 and a speaker unit 132. The speaker housing 131 has a connecting boss 1301 for snap-fit ​​connection with the outer shell 10. The snap-fit ​​connection facilitates the installation and disassembly of the speaker module 13. It provides a tool-free, easy-to-assemble and disassemble, and securely connected assembly method, which ensures the stability of the speaker module 13 during use and is beneficial for subsequent upgrades and maintenance.

[0029] The external module 1 provided in this application embodiment facilitates upgrades and maintenance; for example, if the speaker unit 132 is damaged or the user needs to upgrade the sound quality, there is no need to replace the entire head-mounted device, only the external module or the speaker module therein needs to be replaced, thereby greatly reducing maintenance costs.

[0030] Furthermore, the external module 1 provided in this application embodiment can provide a flexible wearing solution; for example, the external module can be designed to be clipped to the collar, hung on the chest, or worn in other ways, thereby decoupling the acoustic system from the head-mounted device body, reducing the weight of the head-mounted device body, and improving wearing comfort.

[0031] In addition, the external module 1 also includes a connection component 11, which is disposed outside the receiving space and detachably connected to the housing 10. The connection component 11 is configured to be connected to the device body of the head-mounted device; that is, the external module 1 is specifically detachably connected to the device body of the head-mounted device through the connection component 11.

[0032] Reference Figures 2-3 As shown, in one embodiment, the speaker housing 131 has a sound outlet 1310 at a position corresponding to the connecting boss 1301.

[0033] In this specific example, a sound hole 1310 is opened at the position of the connecting boss 1301 on the speaker housing 131, so that the sound can be transmitted more smoothly from the speaker unit 132, which helps to optimize the sound propagation path, improve the sound output effect, and further improve the sound quality performance.

[0034] In other words, by placing the sound outlet 1310 directly at the connecting boss 1301, the sound can be transmitted from the speaker unit 132 in the most direct and lossless manner, reducing the loss and distortion of sound energy in the complex cavity and ensuring sound quality.

[0035] Reference Figures 2-4 As shown, in one embodiment, the speaker housing 131 includes a front shell 1311, a rear shell 1312, and a middle shell 1313. The front shell 1311 and the rear shell 1312 are respectively connected to the middle shell 1313. The front shell 1311 and the middle shell 1313 enclose a front acoustic cavity 1302, and the rear shell 1312 and the middle shell 1313 enclose a rear acoustic cavity 1303. The speaker unit 132 is disposed in the rear acoustic cavity 1303.

[0036] In this specific example, the speaker housing 131 is divided into a front housing 1311, a rear housing 1312, and a middle housing 1313, forming a front acoustic cavity 1302 and a rear acoustic cavity 1303. The speaker unit 132 is then placed in the rear acoustic cavity 1303. This structural arrangement allows for optimization of the frequency response of the sound by rationally designing the volume and shape of the front acoustic cavity 1302 and the rear acoustic cavity 1303, thereby improving the sound quality and timbre and providing a better audio experience. Simultaneously, this split structure facilitates the installation and maintenance of the speaker unit 132.

[0037] Reference Figures 2-4 As shown, in one embodiment, the connecting boss 1301 is formed on the front housing 1311.

[0038] In this specific example, the connecting boss 1301 is formed on the front shell 1311, which makes the positional relationship between the connecting boss 1301 and the sound outlet 1310 more reasonable, so that the sound can be propagated from the sound outlet 1310 through the area near the connecting boss 1301, further optimizing the sound propagation path and helping to improve the output efficiency and quality of the sound.

[0039] Reference Figures 2-4 As shown, in one embodiment, the rear shell 1312 has a sound vent 1300 that communicates with the rear acoustic cavity 1303.

[0040] In this specific example, a vent 1300 is provided in the rear housing 1312, communicating with the rear acoustic cavity 1303. This balances the air pressure inside and outside the rear acoustic cavity 1303, releases pressure within the cavity, and prevents pressure changes from affecting the vibration of the speaker unit 132. This ensures the normal operation of the speaker unit 132 and improves sound stability and quality. Simultaneously, the vent 1300 also provides some heat dissipation, helping to reduce the temperature of the speaker module during operation.

[0041] Reference Figure 4 As shown, in one embodiment, the number of sound vents 1300 is two, and the two sound vents 1300 are arranged opposite to each other.

[0042] In this specific example, setting two opposing vent holes 1300 can more evenly balance the air pressure inside and outside the rear acoustic cavity 1303, further optimize the working environment of the speaker module, reduce sound distortion caused by air pressure imbalance, and improve sound quality and stability.

[0043] Reference Figure 4 As shown, in one embodiment, the length of one of the sound vents 1300 is greater than the length of the other sound vent 1300.

[0044] In this specific example, the length of one of the sound vents 1300 is greater than that of the other sound vent 1300. This asymmetrical design allows for more precise adjustment of the frequency response of the sound by adjusting the parameters of the two sound vents, further optimizing the sound quality and meeting the personalized needs of different users for sound effects.

[0045] Reference Figure 4 As shown, in one embodiment, the speaker module 13 further includes a mesh 133, which is connected to the outer side wall of the rear shell 1312 and covers the sound leakage hole 1300.

[0046] In this specific example, a mesh 133 is connected to the outer wall of the rear shell 1312 of the speaker module and covers the sound vent 1300. The mesh 133 can play a role in dustproofing and waterproofing, preventing dust, water vapor and other substances from entering the rear sound cavity 1303, protecting the speaker unit 132 from damage, and extending the service life of the speaker module. At the same time, the mesh 133 can also filter and modify the sound to a certain extent, improving the sound quality.

[0047] Reference Figure 1 , Figure 5 , Figure 6 As shown, in one embodiment, the outer casing 10 includes a housing 1001 and a base plate 1002. The housing 1001 has an opening extending from an end to a side. The base plate 1002 is engaged with the housing 1001 and covers the opening. The housing 1001 and the base plate 1002 together form the receiving space. The connecting boss 1301 is snapped into the base plate 1002. The base plate 1002 has a sound outlet hole 1000, which is connected to the sound outlet hole 1310.

[0048] In this specific example, the outer casing 10 is a split structure comprising a housing 1001 and a base plate 1002, with the housing 1001 and base plate 1002 engaging. This structural design facilitates the assembly and disassembly of the outer casing 10, and makes it convenient to install and maintain the components within the housing space of the outer casing 10. The connecting boss 1301 engages with the base plate 1002, and the base plate 1002 has a sound outlet 1000 that communicates with the sound outlet 1310 of the speaker module 13, ensuring that sound can be smoothly transmitted from the speaker module 13 to the outside, thus guaranteeing the sound output effect.

[0049] According to another embodiment of this application, refer to Figure 7 As shown, a head-mounted device is provided, which includes an external module 1 as described above; it also includes a device body 2, and the external module 1 and the device body 2 are detachably connected.

[0050] The head-mounted device provided in this application embodiment, by including the aforementioned external module 1, can solve problems such as poor audio quality, short battery life, and difficulties in upgrading and maintenance caused by integrated design, thereby improving the overall performance and user experience of the head-mounted device and making it more competitive in the market. For example, this head-mounted device is a pair of smart glasses.
