Abstract

The present disclosure relates to an in-ear wearable device and a panel assembly thereof. The panel assembly of the in-ear wearable device includes a panel, a mainboard, a manipulation device, a charging device, a battery, an antenna device, a sound pickup device, a speaker assembly, and a wireless communication module. In a plane perpendicular to the panel or the manipulation device, an orthographic projection of the manipulation device partially overlaps an orthographic projection of the charging device; in a plane where the panel or the manipulation device is located, minimum circumscribed circles of the orthographic projections of the manipulation device and the charging device at least partially overlap each other.

Claims (32)

1. A panel assembly of an in-ear wearable device, comprising a panel, a mainboard, a manipulation device, a charging device, a battery, an antenna device, a sound pickup device, a speaker assembly, and a wireless communication module, wherein:

the manipulation device is a touchpad that can be manipulated from above the panel, and the charging device is a device that can charge the in-ear wearable device from above the panel;

in a plane perpendicular to the panel or the manipulation device, an orthographic projection of the manipulation device partially overlaps an orthographic projection of the charging device;

in a plane where the panel or the manipulation device is located, a minimum circumscribed circle of the orthographic projection of the manipulation device at least partially overlaps a minimum circumscribed circle of the orthographic projection of the charging device; and

the charging device comprises a plurality of charging pins extending into an opening of the panel through the manipulation device, and a minimum distance from the plurality of charging pins to an outer contour of the manipulation device is within 2 mm.

2. The panel assembly according to claim 1 , wherein an overlap ratio R of the minimum circumscribed circle of the orthographic projection of the manipulation device and the minimum circumscribed circle of the orthographic projection of the charging device is:

R

=

S

0

max

(

S

1

,

S

2

)

and the overlap ratio R is 70% to 100%,

wherein S 1 represents an area of the minimum circumscribed circle of the orthographic projection of the manipulation device, S 2 represents an area of the minimum circumscribed circle of the orthographic projection of the charging device, S 0 represents an overlap area of the two minimum circumscribed circles, and max (S 1 , S 2 ) represents a larger value of S 1 and S 2 .

3. The panel assembly according to claim 1 , wherein upper ends of the plurality of charging pins are all flush with an upper surface of the panel, or the upper ends of the plurality of charging pins are all lower than the upper surface of the panel, or the upper end of at least one of the plurality of charging pins is flush with the upper surface of the panel and the upper ends of other charging pins are lower than the upper surface of the panel.

4. The panel assembly according to claim 1 , wherein the manipulation device is substantially circular or elliptical, and the minimum circumscribed circle of the manipulation device has a diameter of 5 to 8 mm.

5. The panel assembly according to claim 1 , further comprising a magnet, and the orthographic projections of the manipulation device and the charging device on a cross section of the magnet are located in the cross section.

6. The panel assembly according to claim 1 , wherein when a user wears the in-ear wearable device, a projection of the panel in a direction of the user's ear is located within a contour of the ear.

7. An in-ear wearable device, comprising the panel assembly according to claim 1 and a housing.

8. The in-ear wearable device according to claim 7 , wherein in a plane where the panel or the manipulation device is located, an orthographic projection of the housing covers all or most areas of orthographic projections of the panel, the manipulation device, the charging device, the battery, the antenna device and the sound pickup device,

wherein an orthographic projection of the housing covers most areas of orthographic projections of the panel, the manipulation device, the charging device, the battery, the antenna device and the sound pickup device means that, in a plane where the panel or the manipulation device is located, 85% or more of an area defined by outer contours of the orthographic projections of the panel, the manipulation device, the charging device, the battery, the antenna device, and the sound pickup device is located within the orthographic projection of the housing.

9. The in-ear wearable device according to claim 7 , wherein:

the housing is a customized housing formed based on a shape and a size of a user's ear, comprising a first protruding portion and a second protruding portion; when the user wears the in-ear wearable device, the first protruding portion is located in an auricular concha cavity of the user or the auricular concha cavity and an external acoustic meatus of the user, and the second protruding portion is located in a cymba conchae of the user; and/or

the in-ear wearable device comprises at least one of an in-ear detection sensor, a body temperature sensor, a blood pressure sensor, a blood oxygen sensor, a heart rate sensor, and a blood glucose sensor.

10. The panel assembly according to claim 1 , wherein the manipulation device is substantially circular or elliptical, and the minimum circumscribed circle of the manipulation device has a diameter of 5 to 6 mm.
