[0030] An embodiment of the utility model provides a sound guide device for audio glasses, wherein the temples of the audio glasses have a sound-emitting portion, and the audio glasses are, for example, augmented reality (AR) glasses. In some other embodiments, the audio glasses may also be virtual reality (VR) glasses, Bluetooth audio glasses, and other head-mounted display devices that can emit sound and have a glasses-like appearance.
[0031] Figure 1 It is a three-dimensional schematic diagram of wearing the sound guide device of the utility model. Figure 2 , Figure 3 , Figure 4 and Figure 5 They are respectively a three-dimensional schematic diagram, a front view schematic diagram, a side view schematic diagram and a cross-sectional schematic diagram of the first embodiment of the sound guide device of the utility model.
[0032] The sound guide device includes: a temple connector 100 and a sound guide 200. The temple connector 100 is used for detachably connecting with the temple 300. The sound guide 200 is cross-arranged with the temple connector 100, and the sound guide 200 includes a sound guide channel 210 and a sound outlet hole 220. When the sound guide 200 and the temple connector 100 are connected to the temple, the sound guide channel 210 is connected with the sound-emitting part, and the sound outlet hole 220 is arranged on the side wall of the sound guide 200, and the sound guide channel connects the sound outlet hole with the sound-emitting part. By adopting a structure combining the temple connector 100 and the sound guide 200, and the cross-arrangement of the sound guide 200 and the temple connector 100, this structure can effectively utilize the space of the temple 300, so that the sound guide 200 can be compactly installed on the temple 300 without occupying additional space. It allows users to have a better hearing experience when using audio glasses, avoids the embarrassment of being overheard by others when users make calls or play audio through audio glasses, and protects the privacy of users. At the same time, it allows users to better use audio glasses to obtain audio information in various environments, and will not be unable to hear the sound of audio glasses clearly due to excessive external noise.
[0033] In some embodiments, the temple connector and the sound guide are integrally formed silicone parts. The silicone parts can increase the friction of the sound guide parts. When the user uses it, the silicone parts can increase the fit between the user's face and the sound guide parts, thereby achieving an anti-slip effect. The above implementation improves the wearing experience of audio glasses, enhances the stability when worn, and is less likely to slip or fall.
[0034] In some embodiments, the temple connector 100 is a tubular connector, and the temple connector 100 can be mounted on the temple 300. The temple connector 100 is a tubular connector, and can be mounted on the temple 300. This simple structure makes the installation and use of the sound guide device more convenient and reliable. At the same time, the simple structure also helps to reduce the weight and volume of the device, and improves the comfort and portability of the audio glasses.
[0035] In some embodiments, the sound hole 220 is located at the end of the sound guide 200 away from the temple connector 100, and the sound hole 220 is a mesh structure. The sound hole 220 is located at the end of the sound guide 200 away from the temple connector 100. By setting the sound hole 220 at the end, the reflection and interference of the sound inside the sound guide 200 can be reduced, and the sound propagation effect can be improved. The sound hole 220 adopts a mesh structure, which can effectively avoid the occurrence of occlusion, so that the sound can be freely propagated to the surrounding environment without being hindered or weakened. The mesh structure can ensure the permeability and uniformity of the sound hole 220, and improve the effect and quality of audio transmission.
[0036] In some embodiments, the cross-sectional shape of the sound guide channel 210 is circular or elliptical. A circular or elliptical pipe can conduct sound waves more evenly, and due to its symmetry, the propagation of sound waves in the pipe is less affected by directional changes. This structure is conducive to maintaining the clarity and stability of the sound. The circular or elliptical sound guide channel 210 reduces the edges and corners inside the pipe, thereby reducing the reflection and interference of the sound inside the pipe.
[0037] In some embodiments, the cross-sectional dimensions of the sound guide channel 210 gradually increase or decrease in the direction away from the temple connector 100. The structure of the above embodiment can be applied to the focuser or diffuser of sound waves. The sound guide channel 210 whose cross-sectional dimensions gradually increase in the direction away from the temple connector 100 helps to diffuse the sound, while the sound guide channel 210 whose cross-sectional dimensions gradually decrease in the direction away from the temple connector 100 helps to concentrate and enhance the sound, especially at specific frequencies, which can be used to optimize certain characteristics of the sound, such as improving the clarity of speech. By adjusting the cross-sectional dimensions of the sound guide channel 210, specific characteristics of the sound can be optimized, such as improving the clarity of speech or the sound quality of music. Contracting the sound guide channel 210 at a specific frequency can enhance the sound of that frequency, while expanding the sound guide channel 210 at other frequencies can ensure uniform distribution of the sound, thereby optimizing and enhancing the sound. This allows audio glasses to adjust the sound according to different environments and usage scenarios, enhancing its adaptability and flexibility.
[0038] In some embodiments, the sound guide channel 210 extends in a spiral shape to increase the propagation distance of the sound wave in the pipe. By adjusting the details of the spiral, such as the width, length and number of turns, the quality of the sound, including its pitch, loudness and clarity, can be finely adjusted. The spirally extended sound guide channel 210 helps to optimize specific characteristics of the sound, such as enhancing low-frequency response, improving high-frequency clarity or adjusting the balance of the sound.
[0039] Figure 6 The cross-sectional structure diagram of the second embodiment of the sound guide device of the utility model is shown in FIG. Part of the structure of the second embodiment is the same as that of the first embodiment, and the differences between the two will be described below, and the similarities will not be described in detail.
[0040] In the second embodiment, at least part of the inner wall surface of the sound guide channel 210 is an uneven surface 230. The absorption and scattering characteristics of the sound can be adjusted according to the size and distribution of the uneven surface 230, thereby affecting the clarity and sound quality of the sound. The inner wall of the uneven surface 230 can cause the sound waves to scatter at different angles and directions, thereby increasing the distribution and uniformity of the sound in the surrounding environment. This helps to avoid the concentration and localization of the sound, and improves the naturalness and surround feeling of the sound. By increasing the number and depth of the uneven surface 230, the absorption surface area of the inner wall of the sound guide channel 210 can be increased, thereby enhancing the absorption effect of the sound. This can reduce the reflection and echo of the sound during the sound propagation of the sound guide channel 210, and improve the purity and realism of the sound. By adjusting the distribution and shape of the uneven surface 230, the scattering direction and angle of the sound wave can be affected. Adding an uneven surface 230 at a specific position of the sound guide channel 210 can cause the sound waves to scatter at different angles and directions, thereby increasing the distribution and uniformity of the sound in the surrounding environment.
[0041] Figure 7 The third embodiment of the present invention is a schematic diagram of the cross-sectional structure of the sound guide device. Part of the structure of the third embodiment is the same as that of the first embodiment, and the differences between the two will be described below, and the similarities will not be described in detail.
[0042] In some embodiments, at least part of the inner wall surface of the sound guide channel 210 is provided with a sound absorbing material 240. For example, a material with high sound absorption performance is wrapped or embedded in the sound guide channel 210 to reduce internal reflections and resonances, thereby improving the sound conduction quality. By using the sound absorbing material 240, the energy generated by the resonance can be effectively absorbed, the impact of the resonance effect on the sound can be reduced, and the balance and stability of the sound can be maintained. The sound absorbing material can be a porous sound absorbing material or a resonant sound absorbing material. Reducing internal reflections and resonances can improve the conduction quality of the sound in the sound guide channel 210. The sound will not be excessively disturbed and distorted during the propagation of the sound in the channel, maintaining the accuracy and clarity of the original sound, thereby improving the auditory performance of the audio and the user experience. The structure of the sound absorbing material 240 inside the sound guide channel 210 can reduce the obviousness and sharpness of the sound, making the auditory experience more comfortable.
[0043] Figure 8 1 is a schematic diagram of the structure of the fourth embodiment of the sound guide device of the present invention. Part of the structure of the fourth embodiment is the same as that of the first embodiment, and the differences between the two will be described below, and the similarities will not be described in detail.
[0044] In some embodiments, the sound guide 200 includes at least two pipe segments 250 that are sequentially sleeved along its own extension direction, and the adjacent pipe segments 250 are slidably connected, so that the extended length of the sound guide 200 can be adjusted. The deformable or adjustable length pipe segment 250 allows the user to adjust the length of the sound guide 200 as needed, and sound guides of different lengths can be adapted to the faces of different users, thereby improving the user's wearing experience.
[0045] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
