[0025] As Figure 1As shown, the embodiment of the present application provides a loudspeaker assembly 100 and smart glasses (not shown in the figure), which can be AR glasses or VR glasses. The smart glasses include a lens (not shown in the figure), a frame (not shown in the figure), and a temple (not shown in the figure). The lens is arranged in the frame, and the lens can be a waveguide lens. The temple is connected to the frame. The smart glasses can also include an optical machine (not shown in the figure), which is arranged in the frame and used to emit a light beam to the lens to form an image on the lens and propagate to the eyes of a user, thereby realizing a display function. The temple includes the loudspeaker assembly 100 and a shell 200. The loudspeaker assembly 100 is assembled on the shell 200. Specifically, the number of the shell 200 is two. One of the two shells 200 is an upper shell, and the other is a lower shell. The upper shell and the lower shell are assembled and connected to form a containing space for accommodating electronic devices. The loudspeaker assembly 100 is assembled in the containing space.
[0026] Further, as shown in Figure 2 and Figure 3 The shell 200 is provided with a sound outlet hole 300. The loudspeaker assembly 100 includes a loudspeaker 10 and a loudspeaker support 20. The loudspeaker support 20 is used to fixedly assemble the loudspeaker 10 on the shell 200, for example, on the upper shell or the lower shell. The loudspeaker 10 and the loudspeaker support 20 are assembled and connected to form a first sound cavity 30. The loudspeaker support 20 and the shell 200 are assembled and connected to form a second sound cavity 40. The second sound cavity 40 is in communication with the sound outlet hole 300. The loudspeaker support 20 is provided with an opening 50. The opening 50 is used to communicate the first sound cavity 30 and the second sound cavity 40. The sound emitted by the loudspeaker 10 is transmitted out through the first sound cavity 30, the opening 50, the second sound cavity 40, and the sound outlet hole 300 in sequence. For the first sound cavity 30, from the side far away from the opening 50 to the side close to the opening 50, in the direction perpendicular to the plane where the bottom surface of the loudspeaker 10 is located, which can be understood as the thickness direction of the loudspeaker 10 (as shown by x in Figure 2 The vertical distance between the bottom surface of the loudspeaker 10 and the assembly surface of the loudspeaker support 20 corresponding to the bottom surface gradually increases from the side far away from the opening 50 to the side close to the opening 50. Therefore, from the side far away from the opening 50 to the side close to the opening 50, the size of the first sound cavity 30 in the thickness direction of the loudspeaker 10 gradually increases, so as to increase the radiation angle of the first sound cavity 30, so that the first sound cavity 30 plays a role in amplifying sound, and also enables the sound to be more widely diffused in the first sound cavity 30, thereby improving the sound propagation effect of the loudspeaker assembly 100.
[0027] Meanwhile, the end of the second sound cavity 40 close to the opening 50, for the second sound cavity 40, from the side close to the opening 50 to the side far away from the opening 50, in the direction perpendicular to the plane where the surface of the shell 200 is located, which can be understood as the thickness direction of the loudspeaker 10 (as shown by x in Figure 2As shown in x), the vertical distance between the bottom surface of the speaker bracket 20 and the inner surface of the housing 200 that is fitted thereto gradually increases, so that from the side near the opening 50 to the side away from the opening 50, the size of the second sound cavity 40 in the thickness direction of the speaker 10 gradually increases, so as to increase the radiation angle of the second sound cavity 40, so that the second sound cavity 40 can amplify the sound and also make the sound diffuse more widely in the second sound cavity 40, thereby improving the sound propagation effect of the speaker assembly 100.
[0028] Moreover, the above-mentioned arrangement of the first acoustic cavity 30 and the second acoustic cavity 40 can reduce the resistance to sound propagation in the first acoustic cavity 30 and the second acoustic cavity 40 respectively, thereby reducing the phenomenon of sound energy being reflected back to the diaphragm, and also reducing the sound distortion and interference caused by strong local reflections.
[0029] like Figure 2 As shown, in one specific embodiment, the diaphragm of the loudspeaker 10 is positioned directly opposite the first acoustic cavity 30, so that when the loudspeaker 10 receives an electrical signal and causes the diaphragm to vibrate, the sound emitted by the loudspeaker 10 can enter the first acoustic cavity 30.
[0030] like Figure 2 and Figure 4 As shown, in some embodiments, the speaker bracket 20 includes a bottom wall 21 and a side wall 22 surrounding the outer periphery of the bottom wall 21. The bottom wall 21 is assembled and connected to the housing 200. Specifically, the bottom surface of the bottom wall 21 has a protrusion (not shown) for tightly fitting the housing 200. The protrusion is located on the side of the opening 50 away from the second sound cavity 40, so that the opening 50 is spaced apart from the housing 200. The side wall 22 and the bottom wall 21 form an installation space (not shown). The speaker 10 is tightly fitted and installed in the installation space to fix the speaker 10. Furthermore, the bottom wall 21 is provided with a groove 23. The opening 50 is provided on the bottom wall of the groove 23. The area of the groove 23 outside the opening 50 and the speaker 10 form a first sound cavity 30, so that the first sound cavity 30 is connected to the second sound cavity 40 through the opening 50.
[0031] like Figure 2 and Figure 4 As shown, in some embodiments, in the first acoustic cavity 30, from the side away from the opening 50 to the side adjacent to the opening 50, in a direction perpendicular to the plane of the bottom surface of the speaker 10 (e.g. Figure 2 On the surface of the bottom wall 21 (as shown in x), the upper surface of the bottom wall 21 (as shown in x) Figure 2 The vertical distance between the plane where 21a) is located and the bottom surface 24 of the groove 23 gradually increases, thereby increasing the radiation angle of the first sound cavity 30 and enabling the first sound cavity 30 to amplify the sound.
[0032] like Figure 2 and Figure 4As shown, in some embodiments, the upper surface of the bottom wall 21 (e.g.) Figure 2 The distance between the plane containing 21a) shown and the bottom surface 24 of the groove is h, where 0.6mm≤h≤1.2mm, thus there is a vertical distance between the upper surface of the bottom wall 21 and the bottom surface 24 of the groove 23.
[0033] like Figure 2 and Figure 4 As shown, in some embodiments, the upper surface of the bottom wall 21 (e.g.) Figure 2 The angle between the plane where 21a) is located and the bottom surface 24 of the groove is α, where 20°≤α≤60°, so that the bottom surface 24 of the groove 23 is inclined relative to the plane where the upper surface of the bottom wall 21 is located, thereby gradually increasing the vertical distance between the plane where the upper surface of the bottom wall 21 is located and the bottom surface 24 of the groove 23.
[0034] like Figure 2 As shown, in a specific embodiment, the opening 50 has a side 51 connected to the bottom surface 24 of the groove, and the angle between the plane containing the upper surface of the bottom wall 21 and the side 51 is θ, 20°≤θ≤90°, preferably 20°≤θ≤60°, which facilitates sound propagation.
[0035] like Figure 2 and Figure 4 As shown, in some embodiments, the speaker bracket 20 further includes a surrounding wall 25, which is connected to the side of the side wall 22 away from the speaker 10. The end of the surrounding wall 25 away from the side wall 22 is assembled and connected to the housing 200. The side wall 22, the surrounding wall 25 and the housing 200 form a second sound cavity 40.
[0036] like Figure 2 As shown, in some embodiments, the portion of the enclosure 25 adjacent to the opening 50 is formed by the housing 200 to create a first portion 41 of the second acoustic cavity 40, and the portion of the enclosure 25 away from the opening 50 is formed by the housing 200 to create a second portion 42 of the second acoustic cavity 40. Specifically, the portion of the enclosure 25 adjacent to the opening 50 and the portion of the enclosure 25 away from the opening 50 are integrally formed and connected. For the first portion 41 of the second acoustic cavity 40, from the side adjacent to the opening 50 to the side away from the opening 50, in the direction perpendicular to the plane of the inner surface of the housing 200 (e.g., ... Figure 2 As shown in x), the vertical distance between the inner surface of the housing 200 and its corresponding enclosure 25 gradually increases, thereby increasing the radiation angle of the first part 41 and enabling the first part 41 to amplify the sound.
[0037] Combination Figure 2 In one specific embodiment, the second part 42 of the second acoustic cavity 40 is connected to the rear cavity (not shown), and the second part 42 of the second acoustic cavity 40 can guide the airflow to flow and circulate in the rear cavity in an orderly manner.
[0038] Combination Figure 2 In some embodiments, the angle between the plane containing the bottom surface of the enclosure 25 and the inner surface of the housing 200 is β, where 20°≤β≤85°, so that the bottom surface of the enclosure 25 is inclined relative to the inner surface of the housing 200, and the vertical distance between the bottom surface of the enclosure 25 and the corresponding inner surface of the housing 200 gradually increases, which enables the sound to diffuse more widely.
[0039] like Figure 3 As shown, in some embodiments, the sound outlet 300 is funnel-shaped, which can improve the diffusion angle.
[0040] like Figure 3 As shown, in a specific embodiment, the sound outlet 300 includes a first opening 301 and an annular inclined surface 302 communicating with the first opening 301. The annular inclined surface 302 is arranged around the periphery of the first opening 301 to form a funnel-shaped second opening (not shown). The shape design of the second opening can improve the diffusion angle of the sound outlet 300.
[0041] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the content of this application's specification and drawings under the concept of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
