Abstract

The present disclosure provides a smart speaker, which comprises a first inner casing, a second inner casing, a first housing, a second housing, and a first director group. The first inner casing comprises at least one first speaking unit. The second inner casing is disposed on the first inner casing and comprises at least one second speaking unit and at least one active antenna module. The first housing surrounds and covers the first inner casing, and the second housing surrounds and covers the second inner casing. The first director group is disposed at one side of the second housing facing the second inner casing, and the position of the first director group corresponds to at least one active antenna module.

First claim

What is claimed is:

1. A smart speaker, comprising:
a first inner casing comprising at least one first speaking unit;
a second inner casing disposed on the first inner casing, the second inner casing comprising at least one second speaking unit and at least one active antenna module;
a first housing surrounding and covering the first inner casing;
a second housing surrounding and covering the second inner casing; and
a first director group disposed at one side of the second housing facing the second inner casing, a position of the first director group corresponding to the at least one active antenna module.

2. The smart speaker according to claim 1 , wherein the at least one active antenna module comprises a first active antenna located in a central area of the second inner casing.

3. The smart speaker according to claim 2 , wherein the first director group is located in an electromagnetic field generated by the first active antenna.

4. The smart speaker according to claim 3 , wherein the first director group comprises a first director and a second director; the first director and the second director are oppositely disposed.

5. The smart speaker according to claim 2 , wherein the at least one active antenna module further comprises a second active antenna, a third active antenna, and a fourth active antenna disposed around the first active antenna.

6. The smart speaker according to claim 5 , wherein the second active antenna, the third active antenna, and the fourth active antenna are located between the first active antenna and the at least one second speaking unit.

7. The smart speaker according to claim 1 comprising a second director group comprising a third director and a fourth director, the third director and the fourth director being oppositely disposed.

8. The smart speaker according to claim 7 , wherein the first director group and the second director group are metal director groups generating an induced electric current in an electromagnetic field generated by the at least one active antenna module.

9. The smart speaker according to claim 8 , wherein the first director and the second director are arc-shaped directors; the second housing comprises a center of circle; a first distance exists between a side edge of the arc-shaped director away from the center of circle and the center of circle; the side edge of the arc-shaped director away from the center of circle has a first length.

10. The smart speaker according to claim 7 , wherein the third director and the fourth director are located on a side edge of the second housing and are away from the at least one second speaking unit.
