1. A wireless earset, comprising:
a housing;
a first antenna disposed in a first position in the housing;
a second antenna disposed in a second position in the housing, wherein there is an interval between the first position and the second position, and the first antenna and the second antenna are configured to generate different radiation patterns;
a switching circuit disposed in the housing and selectively electrically connected to the first antenna or the second antenna; and
a control circuit disposed in the housing and electrically connected to the switching circuit, the first antenna, and the second antenna, wherein the control circuit is configured to output a first radio frequency signal and control the switching circuit to switch alternatively to electrically connect the first antenna and the second antenna, so that the first antenna and the second antenna transmit the first radio frequency signal at different times, and the control circuit is configured to obtain and determine a received signal strength of the first antenna and the second antenna after the switching circuit electrically connects the first antenna and the second antenna respectively, and control the switching circuit to electrically connect the first antenna or the second antenna, which has a greater received signal strength, to receive a second radio frequency signal;
wherein the control circuit is configured to control the switching circuit to ground the second antenna when controlling the switching circuit to be electrically connected to the first antenna to increase an area of a ground plate corresponding to the first antenna by incorporating the second antenna into the ground plate; or the control circuit is configured to control the switching circuit to ground the first antenna when controlling the switching circuit to be electrically connected to the second antenna to increase an area of a ground plate corresponding to the second antenna by incorporating the first antenna into the ground plate.
