Abstract: Embodiments of the present invention provide an antenna apparatus. The antenna apparatus includes multiple antennas, a switching unit, a grounding layer, connecting lines and a dielectric substrate. The antennas are configured to transmit and receive electromagnetic waves. The connecting lines are configured to connect the switching unit and the antennas. The switching unit is configured to selectively feed signals to the antennas through the connecting lines. The grounding layer serves as a reference of zero potential, and by setting the shape or size of the grounding layer and the distance from the grounding layer to the antennas, the grounding layer is further configured to restrain a transmitting direction of the electromagnetic waves transmitted by the antennas. The dielectric substrate is configured to allow the grounding layer to be printed thereon, and the dielectric substrate is further configured to allow the antennas, the switching unit and the connecting lines.

Abstract: A voice control method includes establishing, by a terminal, a communication connection to a wearable device, performing, by the terminal, identity authentication on a voicing user based on a first voiceprint recognition result of a first voice component in voice information and a second voiceprint recognition result of a second voice component in the voice information when the voicing user enters the voice information to the wearable device, where the first voice component is collected by a first voice sensor of the wearable device, and the second voice component is collected by a second voice sensor of the wearable device, and executing, by the terminal, an operation instruction corresponding to the voice information when a result of the identity authentication indicates that the voicing user is an authorized user.
