[0047] As Figures 1 to 9As shown, the present application provides an audio mechanism 30, comprising a main body 31 and a sound production device 32, the main body 31 comprises two first side walls 311 arranged oppositely, two second side walls 312 connected between the two first side walls 311 and arranged oppositely, the main body 31 is provided with a receiving cavity 313, a sound outlet hole 3133 and a sound leakage hole 3134; the sound production device 32 is arranged in the receiving cavity 313 by a bearing bracket 33, the sound production device 32, the bearing bracket 33, the first side wall 311 and the second side wall 312 cooperate to divide the receiving cavity 313 into a front cavity 3131 and a rear cavity 3132 which are independent of each other; wherein the sound outlet hole 3133 is arranged to make the front cavity 3131 communicate with the outside, and the sound leakage hole 3134 is arranged to make the rear cavity 3132 communicate with the outside.

[0048] When assembling the sound production device 32 into the main body 31, the sound production device 32 can be assembled with the bearing bracket 33 first, and then the sound production device 32 and the bearing bracket 33 are assembled into the main body 31 as a whole structure, so that the audio mechanism can be quickly installed in the main body 31, thereby improving the assembly efficiency of the audio mechanism, and reducing the dependence on the internal structure of the main body 31, facilitating the installation of the audio mechanism into different smart glasses products.

[0049] In this embodiment, as shown in Figures 1 to 8 The cross-sectional profile of the main body 31 is not strictly limited; for example, the cross-sectional profile of the main body 31 is rectangular, elliptical or irregular shape. The two first side walls 311 are respectively a bottom wall 3111 and a top wall 3112; the two second side walls 312 are respectively an inner side wall 3121 and an outer side wall 3122. Regardless of the shape of the cross-section of the main body 31, it can always be defined that the side facing the user's ear is the bottom wall 3111, the side away from the user's ear is the top wall 3112, the side facing the user's head is the inner side wall 3121, and the side away from the user's head is the outer side wall 3122.

[0050] In this embodiment, as shown in Figure 2 and Figures 6 to 8 The main body 31 is provided with a first barrier wall 315 and a second barrier wall 316 along the length direction, the first barrier wall 315, the second barrier wall 316 and the first side wall 311 and the second side wall 312 of the main body 31 enclose the closed receiving cavity 313, and the bearing bracket 33 is arranged in the receiving cavity 313.

[0051] In this embodiment, as shown in Figures 1 to 2As shown, the main body 31 comprises a front shell 301 and a rear cover 302; the rear cover 302 is located on the side of the main body 31 close to the user's head relative to the shell. The rear cover 302 comprises an inner side wall 3121; the front shell 301 comprises a top wall 3112, a bottom wall 3111 and an outer side wall 3122. The side of the front shell 301 facing the rear cover 302 is a mounting space with an open side, and the rear cover 302 covers and seals the open side of the front shell 301 and forms a containing cavity 313 with the front shell 301. The front shell 301 and the rear cover 302 can be sealed and connected by buckling, gluing, welding, screws, etc. to improve the overall waterproofness of the audio mechanism 30.

[0052] In this embodiment, as shown in the figure, Figures 1 to 2 The main body 31 is located on the user's ear, and the main body 31 can be divided into two sections. Specifically, the main body 31 comprises a connecting section 303 and an arc-shaped section 304; the connecting section 303 is generally in a strip-shaped structure and is located in front of the user's ear; the arc-shaped section 304 is located above the user's ear.

[0053] In this embodiment, as shown in the figure, Figures 2 to 7 When the carrying bracket 33 and the sound emitting device 32 are located in the main body 31, the front cavity 3131 and the rear cavity 3132 are not communicated. The front cavity 3131 and the rear cavity 3132 are respectively arranged on both sides of the main body 31 in the width direction (i.e. the direction from the outer side wall 3122 to the inner side wall 3121). The front cavity 3131 is located on the side close to the outer side wall 3122, and the rear cavity 3132 is located on the side close to the inner side wall 3121. Of course, in other embodiments, the front cavity 3131 can also be located on the side close to the inner side wall 3121, and the rear cavity 3132 can also be located on the side close to the outer side wall 3122.

[0054] In this embodiment, as shown in the figure, Figures 2 to 7 The sound outlet hole 3133 and the sound leakage hole 3134 are located on opposite sides of the main body 31; the first sound wave emitted by the front cavity 3131 enters the human ear through the sound outlet hole 3133 and is heard by the user, and the second sound wave emitted by the rear cavity 3132 is radiated to the outside through the sound leakage hole 3134, and the phase of the first sound wave and the second sound wave in the outside is opposite to cancel each other out, which can reduce the sound leakage and improve the sound effect. Specifically, the sound outlet hole 3133 is opened on the bottom wall 3111 and is close to the user's ear position, which reduces the distance between the sound outlet hole and the ear, facilitates the sound flowing out of the sound outlet hole to be directly transmitted to the ear, ensures the transmission of the sound, so that the user can clearly hear the sound emitted by the front cavity 3131; the sound leakage hole 3134 is opened on the top wall 3112.

[0055] In this embodiment, as shown in the figure, Figures 2 to 7As shown, the sound outlet hole 3133 is in a long strip structure, and is integrated at the joint between the end of the connecting section 303 and the start of the arc section 304. The sound outlet hole 3133 extends longitudinally along the length direction of the main body 31, and spans the transition area between the connecting section 303 and the arc section 304, so as to ensure sound transmission while optimizing wearing comfort and concealment. Of course, in other embodiments, the sound outlet hole 3133 can be located in the arc section 304 and adjacent to the connecting section 303. When the user wears the audio mechanism 30, the sound outlet hole 3133 is arranged towards the ear canal so that the user can clearly hear the sound from the sound outlet hole 3133. The sound leakage hole 3134 is in a long strip structure. The sound leakage hole 3134 can be located in the connecting section 303 and adjacent to the arc section 304. The dustproof net 314 is arranged in the sound outlet hole 3133 and the sound leakage hole 3134, so as to prevent dust from entering the accommodating cavity 313.

[0056] In this embodiment, as shown in the drawings, Figures 2 to 7 The sound amplification channel 3135 is arranged between the front cavity 3131 and the sound outlet hole 3133, and the volume of the sound amplification channel 3135 gradually increases from the front cavity 3131 to the sound outlet hole 3133, so as to amplify the sound and improve the listening experience of the user. The inner wall of the sound amplification channel 3135 is treated to be smooth, so as to reduce the loss of sound in the propagation process. In order to form the sound amplification channel 3135, in one embodiment, the part of the carrying support 33 gradually moves away from the inner wall of the main body 31 from the front cavity 3131 to the sound outlet hole 3133, so as to form the sound amplification channel 3135 between the carrying support 33 and the inner wall of the main body 31.

[0057] In this embodiment, as shown in the drawings, Figures 2 to 7 The sound generating device 32 can be a loudspeaker. The sound generating device 32 is located in the connecting section 303 and adjacent to the arc section 304, so as to shorten the distance between the sound generating device 32 and the ear of the user and reduce the sound loss. The sound generating device 32 can be vertically installed in the main body 31, that is, the plane where the diaphragm of the sound generating device 32 is located is opposite to the inner side wall 3121 and the outer side wall 3122 of the main body 31. The sound generating side of the sound generating device 32 faces the front cavity 3131, so as to ensure that the sound of the sound generating device 32 is transmitted out through the sound outlet hole 3133.

[0058] In this embodiment, as shown in the drawings, Figures 2 to 8 The carrying support 33 has a mounting area 331 and a communication hole 332. The sound generating device 32 is mounted in the mounting area 331. The communication hole 332 penetrates the carrying support 33, so that the sound generating device 32 communicates with the front cavity 3131 through the communication hole 332, that is, the sound generating device 32 is located in the rear cavity 3132. The sound generated by the sound generating device 32 can be smoothly transmitted to the front cavity 3131 through the communication hole 332, and then transmitted to the outside through the sound outlet hole 3133.

[0059] In the embodiment, as shown in Figures 2 to 8 the bearing bracket 33 is recessed towards one side of the rear cavity 3132 to form a mounting area 331; at least part of the sound production device 32 is mounted in the mounting area 331. The sound production device 32 can be fixed with the bearing bracket 33 by means of adhesion, so as to be able to strengthen the connection strength of the sound production device 32 and the bearing bracket 33. The communication hole 332 is located at the bottom of the mounting area 331, so that one side of the sound production device 32 towards the front cavity 3131 is exposed, so as to be able to ensure that the sound of the sound production device 32 is smoothly transmitted to the front cavity 3131 through the communication hole 332.

[0060] In the embodiment, as shown in Figures 2 to 8 the bearing bracket 33 is bonded between the first side wall 311 and the second side wall 312, so as to be able to strengthen the connection strength of the bearing bracket 33 and the main body 31. When the sound production device 32 is mounted in the mounting area 331, the sound production device 32, the bearing bracket 33, the first side wall 311 and the second side wall 312 jointly enclose the front cavity 3131 or the rear cavity 3132.

[0061] In the embodiment, as shown in Figures 8 to 9 the first side wall 311 and the second side wall 312 of the main body 31 are provided with a protrusion 35, and the bearing bracket 33 can be bonded with the protrusion 35. The protrusion 35 can support the bearing bracket 33 and help to further fix the position of the bearing bracket 33, thereby improving the stability of the audio mechanism 30 as a whole. When the bearing bracket 33 is installed in place, the protrusion 35 can support and limit the bearing bracket 33, preventing the bearing bracket 33 from shaking in the main body 31, thereby ensuring the stability and reliability of the audio mechanism 30. Specifically, the inner wall of the outer side wall 3122 of the main body 31 is provided with protrusions 35 arranged continuously or at intervals along the bearing bracket 33, and the bearing bracket 33 can abut against and be bonded with the protrusions 35.

[0062] In the embodiment, as shown in Figures 2 to 8 the audio mechanism 30 further comprises a clamping structure 34 to stabilize the bonding of the bearing bracket 33 relative to the main body 31. When the bearing bracket 33 is assembled into the main body 31, the bearing bracket 33 is clamped and fixed to the main body 31 by the clamping structure 34, and then is adhesively fixed. This not only simplifies the assembly process of the bearing bracket 33, but also greatly improves the stability and durability of the overall structure, avoids the problem of loose parts caused by long-term use or external environmental factors, and ensures the continuous stability and reliability of audio output. The number of clamping structures 34 can be 1 set, 2 sets, 3 sets, 4 sets or more than 4 sets; multiple clamping structures 34 are arranged at intervals along the circumference of the bearing bracket 33.

[0063] In the embodiment, as shown inFigures 2 to 8 As shown, the clamping structure 34 comprises a clamping tongue 341 and a clamping portion 342; the clamping tongue 341 is installed on one of the main body 31 and the bearing support 33; the clamping portion 342 is arranged on the other one of the main body 31 and the bearing support 33; the clamping tongue 341 cooperates with the clamping portion 342 to mount the bearing support 33 on the main body 31. The clamping tongue 341 cooperates with the clamping portion 342 to achieve a stable connection between the bearing support 33 and the main body 31. The clamping portion 342 and the protrusion 35 form a mounting gap; after the clamping tongue 341 passes the clamping portion 342, it is located in the mounting gap and abuts against the side of the clamping portion 342 facing the protrusion 35.

[0064] In order to facilitate the clamping tongue 341 to pass the clamping portion 342, in one of the embodiments, as shown in Figures 2 to 8 The clamping tongue 341 is installed on the main body 31 or the bearing support 33 through an elastic arm 343, so that the clamping tongue 341 can be elastically deformed to facilitate the passing of the clamping portion 342. The clamping tongue 341 can be elastically deformed to conveniently pass the clamping portion 342 during installation, and after installation, the clamping tongue 341 returns to its original shape and tightly cooperates with the clamping portion 342 to prevent the bearing support 33 from loosening. The elastic arm 343 can be a component with elasticity itself, or a component that can be deformed under stress.

[0065] In the embodiment, as shown in Figures 2 to 8 The clamping tongue 341 is installed on the bearing support 33 through the elastic arm 343; and the clamping portion 342 protrudes outwardly from the inner wall of the main body 31. The clamping portion 342 is integrally arranged on the inner wall of the main body 31 to enhance the structural strength between the clamping portion 342 and the main body 31, and to reduce the processing difficulty of the clamping portion 342 and the main body 31. The clamping tongue 341 is integrally arranged on the bearing support 33 to enhance the structural strength between the clamping tongue 341 and the bearing support 33, and to reduce the processing difficulty of the clamping tongue 341 and the bearing support 33.

[0066] In the embodiment, as shown in Figures 8 to 9 One of the main body 31 and the bearing support 33 has a positioning groove 36, and the other one has a positioning protrusion 37 matched with the positioning groove 36. Through the cooperation of the positioning groove 36 and the positioning protrusion 37, the installation position of the bearing support 33 in the main body 31 can be ensured to be accurate, deviation during installation can be avoided, and the performance stability of the audio mechanism 30 can be ensured.
