Smart wearable device
View Patent ↗The present invention provides a smart wearable device includes a glass frame and two temples. Each temple includes a shelf, a cover plate, and a speaker. The speaker includes a first and a second sounding surface. The shelf includes an upper wall, a lower wall, and an outer wall. The upper wall has a first sound hole, the lower wall has a second sound hole, the outer wall has a third sound hole. The speaker has an inner cavity communicated with the first sound hole. The first sounding surface is communicated with the second sound hole. The second sounding surface is communicated with the third sound hole. Two front cavities of the smart wearable device of present invention are independent of each other, and each has an independent sound hole, so that the two cavities can independently produce sound, the back cavity plays a role in preventing sound leakage.
1 . A smart wearable device, comprising:
a glass frame; and
a pair of temples extending backward from both sides of the glass frame, each temple comprising:
a shelf, the shelf comprising:
an upper wall, the upper wall provided with a first sound hole;
a lower wall opposite to the upper wall, the lower wall provided with a second sound hole; and
an outer wall connecting the upper wall and lower wall, the outer wall provided with a third sound hole;
a cover plate covered with the shelf to form a receiving space, the cover plate arranged opposite to the outer wall; and
a speaker received in the receiving space, the speaker having an inner cavity communicated with the first sound hole, the speaker comprising a first sounding surface and a second sounding surface opposite to the first sounding surface, the first sounding surface communicated with the second sound hole, and the second sounding surface communicated with the third sound hole;
wherein the smart wearable device further comprises a first bracket supporting the speaker in the receiving space, one end of the first bracket fixed with the upper wall of the shelf, and the other end of the first bracket fixed with the lower wall of the shelf, a first front cavity formed between the first bracket and the first sounding surface of the speaker, the first front cavity guiding a sound emitted by the first sounding surface out of the second sound hole.
2 . The smart wearable device as described in claim 1 , wherein the smart wearable device further comprises a second bracket supporting the speaker in the receiving space, a second front cavity formed by the second bracket, the second sounding surface of the speaker, and the outer wall of the shelf, the second front cavity guiding a sound emitted by the second sounding surface out of the third sound hole.
3 . The smart wearable device as described in claim 2 , wherein the first bracket, the second bracket and the shelf form a back cavity communicated with the inner cavity of the speaker, the back cavity arranged around the speaker, and the back cavity guiding a sound from the inner cavity out of the first sound hole.
4 . The smart wearable device as described in claim 2 , wherein the second bracket is an annular structure, a second foam disposed between the second bracket and the shelf surrounding the third sound hole.
5 . The smart wearable device as described in claim 4 , wherein the second foam is fixed to the shelf or/and the second bracket by gluing.
6 . The smart wearable device as described in claim 3 , wherein a third foam is disposed between the first bracket and the shelf surrounding the first sound hole, and between the second bracket and the shelf surrounding the first sound hole.
7 . The smart wearable device as described in claim 6 , wherein the third foam is fixed to the shelf, or/and the first bracket, or/and the second bracket by gluing.
8 . The smart wearable device as described in claim 1 , wherein the first bracket comprises a main body and an extension body extending from the main body, the extension body having a shape corresponding to the second sound hole, a first foam disposed between the extension body and the shelf surrounding the second sound hole.
9 . The smart wearable device as described in claim 8 , wherein the first foam is fixed to the shelf or/and the first bracket by gluing.
10 . The smart wearable device as described in claim 1 , wherein the smart wearable device further comprises a plurality of meshes correspondingly attached to the first sound hole, the second sound hole, and the third sound hole.
