3. The wireless listening device according to claim 1 , wherein the panel portion is substantially circular, elliptical, or polygonal.
4. The wireless listening device according to claim 1 , wherein the top cover further comprises at least one lug portion, which is arranged at an outer periphery of the central bumped portion and forms a groove opened toward the interior of the wireless listening device.
5. The wireless listening device according to claim 4 , wherein in the plane where the panel portion is located, a maximum distance L between an outer contour of an orthographic projection of the lug portion and a center of the minimum circumscribed circle is in a range of 8 mm to 12 mm.
6. The wireless listening device according to claim 1 , further comprising:
a first microphone comprising a first sound pickup hole; and
a second microphone comprising a second sound pickup hole,
wherein the manipulation device is substantially in a flat plate shape, and the charging device comprises a charging pin,
wherein in a plane perpendicular to the manipulation device, an orthographic projection of the manipulation device partially overlaps an orthographic projection of the charging pin,
wherein in a plane where the manipulation device is located, an outer contour of the orthographic projections of the manipulation device and the charging pin has a minimum circumscribed circle, and a connecting line between an orthographic projection of the first sound pickup hole and a center of the minimum circumscribed circle forms an included angle α in a range of 100° to 140° with a connecting line between an orthographic projection of the second sound pickup hole and the center of the minimum circumscribed circle.
7. The wireless listening device according to claim 6 , wherein a diameter d of the minimum circumscribed circle of the outer contour of the orthographic projections of the manipulation device and the charging pin is 5 mm to 6 mm.
8. The wireless listening device according to claim 6 , wherein in the plane where the manipulation device is located, the minimum circumscribed circle of the orthographic projection of the charging pin at least partially overlaps the manipulation device.
9. The wireless listening device according to claim 6 , further comprising a magnet, wherein in the plane perpendicular to the manipulation device, orthographic projections of the first microphone, the second microphone, and the magnet at least partially overlap.
10. The wireless listening device according to claim 6 , further comprising a mainboard which comprises a planar section extending substantially parallel to the manipulation device, and the first microphone and the second microphone are both fixed in the planar section.
11. The wireless listening device according to claim 1 , wherein the antenna is configured as a metal circuit formed on a sidewall of the accommodating groove or configured as a metal sheet extending along the sidewall of the accommodating groove.
12. The wireless listening device according to claim 1 , wherein the cover plate is further configured with a joint portion, which is connected to an end of the raised portion opposite to the panel portion and at least partially extends toward the housing in a plane parallel to the panel portion.
