[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Referring to Figures 1-6 , the present invention provides a smart wearable device 100 suitable for gesture recognition or mode adjustment. The smart wearable device 100 includes a frame 101 and a pair of temples 102 extending rearward from both sides of the frame 101. Lenses can be mounted on the frame 101. The pair of temples 102 have identical structures and are axially symmetrical.

[0024] The temple 102 includes a frame 1 having a receiving space 10, a speaker unit 2 received in the receiving space 10, a microphone unit 3, a first bracket 4 and a second bracket 5 supporting the speaker unit 2 in the receiving space 10, foam 6 and a breathable isolation member 7.

[0025] The frame 1 includes an upper wall 11, a lower wall 12 opposite the upper wall 11, and an outer wall 13 and an inner wall 14 connecting the upper and lower walls 11 and 12. The outer wall 13 is located away from the ear, and the inner wall 14 is located closer to the ear. The upper wall 11 is provided with an air vent 111, the lower wall 12 is provided with a main sound outlet 121, and the outer wall 13 is provided with an auxiliary sound outlet 131 and a microphone sound hole 132 located near the auxiliary sound outlet 131. The frame 1 can be a split or integrated structure.

[0026] The speaker unit 2 includes a first sound-emitting surface 21 and a second sound-emitting surface 22 disposed opposite the first sound-emitting surface 21. The speaker unit 2 has an inner cavity 20, and the air vent 111 is connected to the inner cavity 20 of the speaker unit 2. The inner cavity 20 is the space formed between the first sound-emitting surface 21 and the second sound-emitting surface 22 of the speaker unit 2. The main sound outlet 121 is connected to the first sound-emitting surface 21 of the speaker unit 2, and the auxiliary sound outlet 131 is connected to the second sound-emitting surface 22 of the speaker unit 2.

[0027] Specifically, the speaker unit 2 is a speaker monomer, the first sound-emitting surface 21 is arranged on one side of the speaker monomer, and the second sound-emitting surface 22 is arranged on the other side of the speaker monomer. In this case, the smart wearable device 100 only has one double-sided sound-emitting speaker monomer, and the speaker monomer also has only one inner cavity 20. In another embodiment, the speaker unit 2 includes a first speaker monomer and a second speaker monomer, the first sound-emitting surface 21 is arranged on the first speaker monomer, and the second sound-emitting surface 22 is arranged on the second speaker monomer. In this case, the smart wearable device 100 has two sound-emitting speaker monomers, and the inner cavities of the two speaker monomers are connected to each other. The first sound-emitting surface 21 and the second sound-emitting surface 22 can emit sound in normal working mode. In other working modes, the second sound-emitting surface 22 can emit ultrasonic signals and emit them through the auxiliary sound outlet 131.

[0028] The microphone sound unit 3 is disposed within the frame 1 and is connected to the microphone sound hole 132. The ultrasonic signal emitted through the auxiliary sound hole 131 is reflected by an obstacle and then reaches the microphone unit 3 through the microphone sound hole 132, thereby realizing the function of gesture recognition. Alternatively, the process can identify the distance between the user and other people in the surrounding environment as a reference condition for mode adjustment. Specifically, if the distance between the user and other people is determined to be relatively far, the high-pitched mode can be activated. If the distance between the user and other people is determined to be relatively close, the silent mode or the bass mode can be activated. Therefore, the smart wearable device 100 of the present invention realizes the diversity of functions.

[0029] One end of the first bracket 4 is fixed to the upper wall 11 of the frame 1, and the other end is fixed to the lower wall 12 of the frame 1. A first front cavity 40 is formed between the first bracket 4 and the first sound-emitting surface 21 of the speaker unit 2. The first front cavity 40 guides the sound emitted by the first sound-emitting surface 21 to the main sound outlet 121. The first bracket 4 includes a main body 41 and an extension 42 extending from the main body 41 to form a shape corresponding to the main sound outlet 121. The foam 6 is provided between the extension 42 and the frame 1 surrounding the main sound outlet 121. The foam 6 has an annular structure and can be fixed to the frame 1 and the first bracket 4 by glue.

[0030] A second front cavity 50 is formed between the second bracket 5, the second sound-emitting surface 22 of the speaker unit 2, and the outer wall 13 of the frame 1. The second front cavity 50 directs the sound emitted from the second sound-emitting surface 22 toward the secondary sound outlet 131. The second bracket 5 is annular in structure. Foam can also be placed between the second bracket 5 and the frame 1 surrounding the secondary sound outlet 131. The foam can also be secured to the frame 1 and the second bracket 5 using glue.

[0031] The first bracket 4 , the second bracket 5 and the frame 1 form a rear cavity 201 connected to the inner cavity 20 of the speaker unit 2 . The rear cavity 201 is an annular structure and is arranged around the speaker unit 2 . The rear cavity 201 is connected to the air vent 111 on the frame 1 .

[0032] The breathable spacer 7 is attached to the air vent 111, and / or the main sound outlet 121, and / or the auxiliary sound outlet 131, and / or the microphone sound hole 132. The breathable spacer 7 can prevent dust or moisture from entering the receiving space 10 in the temple 102.

[0033] Compared with related technologies, the smart wearable device provided by the present invention includes a frame and a pair of temples extending backward from both sides of the frame, the temples including a frame having a receiving space, a speaker unit and a microphone unit received in the receiving space, the speaker unit including a first sound-emitting surface and a second sound-emitting surface disposed opposite the first sound-emitting surface, the frame including an upper wall, a lower wall opposite the upper wall, and an outer wall connecting the upper and lower walls, the lower wall being provided with a main sound-emitting hole, the outer wall being provided with a secondary sound-emitting hole, the main sound-emitting hole being connected to the first sound-emitting surface of the speaker unit, the secondary sound-emitting hole being connected to the second sound-emitting surface of the speaker unit, the outer wall of the frame being provided with a microphone hole near the secondary sound-emitting hole, the microphone hole being connected to the microphone unit, and the ultrasonic signal emitted by the secondary sound-emitting hole being reflected from the microphone hole to reach the microphone unit.
