The third foam pad 63 is secured to the frame 1, the first bracket 4, and the second bracket 5 by adhesive dispensing.

[0034] The third foam 63 is also an annular structure. The back cavity 203 is isolated from the first front cavity 201 and the second front cavity 202. Due to the third foam 62, the first front cavity 201, the second front cavity 202 and the back cavity 203 are better sealed.

[0035] The smart wearable device 100 further includes a breathable spacer 7 attached to the first sound outlet 111, the second sound outlet 121, and the third sound outlet 131. The breathable spacer 7 can prevent dust or moisture from entering the receiving space 10 in the temple 102.

[0036] Compared with the related art, 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 include a frame, a cover plate covering the frame to form a receiving space, and a speaker unit accommodated in the receiving space, the speaker unit includes a first sound-emitting surface and a second sound-emitting surface opposite to the first sound-emitting surface, the frame includes an upper wall, a lower wall opposite to the upper wall, and an outer wall connecting the upper wall and the lower wall, the cover plate is arranged opposite to the outer wall, the upper wall is provided with a first sound outlet hole, the lower wall is provided with a second sound outlet hole, and the outer wall is provided with a third sound outlet hole, the first sound outlet hole is connected to the inner cavity of the speaker unit, the second sound outlet hole is connected to the first sound outlet surface of the speaker unit, and the third sound outlet hole is connected to the second sound outlet surface of the speaker unit. The two front cavities of the smart wearable device of the present invention are independent of each other and each has an independent sound outlet, so that the two front cavities can emit sound independently. The rear cavity plays a role in preventing sound leakage. The sound cavity led out of the rear cavity offsets the sound cavity led out of the two front cavities, so that when the smart wearable device is in use, other people will not hear the sound emitted by the smart wearable device, and the privacy is high.
