Abstract

The present disclosure provides eyeglasses including: an eyeglass rim; an eyeglass temple, the eyeglass temple comprising a control circuit or a battery; a rotating shaft, the rotating shaft being configured to connect the eyeglass rim and the eyeglass temple, so that the eyeglass rim and the eyeglass temple are relatively rotated around the rotating shaft, and the rotating shaft being disposed with a rotating shaft wiring channel along an axial direction; and a speaker, the speaker comprising an earphone core, the speaker being connected to the eyeglass temple, the control circuit or battery in the eyeglass temple driving the earphone core to vibrate through the connection wire, wherein the earphone core vibrates to generate a driving force to drive a housing panel of the speaker to vibrate, and a straight line of the driving force being not parallel to a normal line of the housing panel.

First claim

What is claimed is:

1. A pair of eyeglasses, wherein the eyeglasses include:
an eyeglass rim;
an eyeglass temple;

a speaker, the speaker comprising a core housing and an earphone core, the speaker being connected to the eyeglass temple;
a first microphone and a second microphone disposed in the eyeglass temple; and
a first sound inlet and a second sound inlet disposed on the eyeglass temple, wherein the first microphone and the second microphone collect external sound through the first sound inlet and the second sound inlet, respectively, wherein
the shaft includes a first shaft;
two ends of the first shaft are respectively connected to the eyeglass rim and the eyeglass temple;
the shaft is disposed with a shaft wiring channel disposed along an axial direction of the first shaft; and
the shaft wiring channel communicates with an outside through a first wiring port disposed on an end surface of the first shaft and a second wiring port disposed on a side wall of the first shaft,
the first shaft is fixedly connected to the eyeglass temple that is disposed near the second wiring port, and rotatably connected to the eyeglass rim that is disposed near the first wiring port, wherein
the eyeglasses further include a connection wire, the connection wire extending to the eyeglass rim and the eyeglass temple through the first wiring port and the second wiring port, respectively.

2. The eyeglasses of claim 1 , further comprising:
a spectacle lens disposed with a vent hole.

3. The eyeglasses of claim 1 , wherein the shaft further comprises a second shaft that is coaxial with and spaced from the first shaft;
the eyeglass rim includes a first lug, and the eyeglass temple includes a second lug and a third lug disposed at intervals;
end portions of the first shaft and the second shaft close to each other are connected to the first lug, end portions of the first shaft and the second shaft away from each other are connected to the second lug and the third lug, respectively, so as to keep the first lug between the second lug and the third lug.

4. The eyeglasses of claim 3 , wherein
the first wiring port is disposed on an end surface of the first shaft close to the second shaft;
the second wiring port is disposed on a side wall of the first shaft close to the second lug; and
the first shaft is rotatably connected to the first lug and fixedly connected to the second lug.

5. The eyeglasses of claim 4 , wherein
the first lug and the second lug are coaxially disposed with a first accommodating hole and a second accommodating hole; and
sizes of the first accommodating hole and the second accommodating hole are disposed to allow the first shaft to be inserted into the first accommodating hole from outside of the eyeglass temple via the second accommodating hole and allow the first shaft in an interference fit with the second accommodating hole and in a clearance fit with the first accommodating hole.

6. The eyeglasses of claim 4 , wherein
the first lug and the third lug are coaxially disposed with a third accommodating hole and a fourth accommodating hole; and
sizes of the third accommodating hole and the fourth accommodating hole are disposed to allow the second shaft to be inserted into the third accommodating hole from outside of the eyeglass temple via the fourth accommodating hole and allow the second shaft in an interference fit with the third accommodating hole and in a clearance fit with the fourth accommodating hole, or allow the second shaft in a clearance fit with the third accommodating hole and in an interference fit with the fourth accommodating hole.

7. The eyeglasses of claim 6 , wherein
the second shaft is a solid shaft;
a diameter of the second shaft is less than a diameter of the first shaft;
in a wearing state, the second shaft is located at an upper side of the eyeglass temple, and the first shaft is located at a lower side of the eyeglass temple; and
a connection between the end surface of the first shaft for disposing the first wiring port and a surface of an inner wall of the first shaft for defining the shaft wiring channel is an arc shape.

8. The eyeglasses of claim 1 , wherein the first microphone and the second microphone are disposed at different positions of a circuit board.

9. The eyeglasses of claim 8 , wherein the circuit board at least comprises a number of first pads and a number of second pads;
at least one of the number of first pads is electrically connected to an audio signal wire of a control circuit, the at least one first pad is electrically connected to at least one of the number of second pads via a first flexible lead on the circuit board, and the at least one second pad is electrically connected to the earphone core via an external wire; and
at least another one of the number of first pads is electrically connected to an auxiliary signal wire of the control circuit, and the at least another one first pad is electrically connected to at least one of the first microphone and the second microphone via a second flexible lead on the circuit board.

10. The eyeglasses of claim 9 , wherein
the circuit board includes at least a main circuit board, a first branch circuit board, and a second branch circuit board;
the first branch circuit board is connected to the main circuit board, away from the main circuit board, and extend along one end of the main circuit board;
the second branch circuit board is connected to the main circuit board, away from the main circuit board, extends along the other end of the main circuit board, and is spaced apart from the first branch circuit board;
the first microphone is disposed on the first branch circuit board; and
the second microphone is disposed on the second branch circuit board.

11. The eyeglasses of claim 10 , wherein
the number of first pads are disposed on the main circuit board;
the at least one second pad is disposed on the first branch circuit board; and
other second pads of the number of second pads are disposed on the second branch circuit board.

12. The eyeglasses of claim 10 , wherein the first branch circuit board extends in a same direction as the main circuit board, and the second branch circuit board extends perpendicular to the main circuit board.

13. The eyeglasses of claim 9 , wherein the earphone core includes:
