Abstract

User convenience is reduced if vibration of a power receiver is inhibited when the power receiver is receiving power through a cable or when the power transmitting region is large and vibration of the power receiver does not cause the power receiver to deviate from a power transmitting region of a power transmitter. It is desired to selectively inhibit the vibration of the power receiver during power reception, depending on the power reception status. The power receiver includes a vibrating unit, and includes a power receiving unit configured to receive power, an identifying unit configured to identify a power reception technique used in the power receiving unit when the power receiving unit receives the power, and an inhibiting unit configured to inhibit the vibrating unit from vibrating in accordance with the identification by the identifying unit.

Claims

1. A power receiver including a vibrating unit, the power receiver comprising:

a power receiving unit configured to receive power;

an identifying unit configured to identify a power reception technique used in the power receiving unit when the power receiving unit receives the power; and

an inhibiting unit configured to inhibit the vibrating unit from vibrating in accordance with the identification by the identifying unit.

2. The power receiver according to claim 1, wherein the power reception technique is a technique of receiving power with a wire or a technique of receiving power wirelessly.

3. The power receiver according to claim 2, wherein the technique of receiving power wirelessly is a technique of receiving power using electromagnetic induction or a technique of receiving power using magnetic resonance.

4. The power receiver according to claim 1,

wherein the inhibiting unit does not inhibit the vibrating unit from vibrating when the technique of receiving power using magnetic resonance is used and

wherein the inhibiting unit inhibits the vibrating unit from vibrating when the technique of receiving power using electromagnetic induction is used.

5. The power receiver according to claim 1, wherein, when the power receiving unit receives the power using electromagnetic induction, the inhibiting unit inhibits the vibrating unit from vibrating depending on a positional relationship between a power transmitting region of a power transmitter and the power receiving unit.

6. The power receiver according to claim 1, further comprising a speaker that outputs sound,

wherein, when the power receiver outputs the sound using the speaker, the inhibiting unit inhibits the vibrating unit from vibrating.

7. The power receiver according to claim 1, further comprising a determining unit configured to determine efficiency in power reception of the power receiving unit,

wherein the inhibiting unit inhibits the vibrating unit from vibrating when the efficiency is less than a predetermined value.

8. The power receiver according to claim 1, wherein, when the power reception by the power receiving unit is completed, the inhibiting unit removes the inhibition of the vibration of the vibrating unit.

9. The power receiver according to claim 1, further comprising a notifying unit that provides a user with notification using sound or indication instead of the vibration by the vibrating unit when the inhibiting unit inhibits the vibrating unit from vibrating.

13. A program for causing a computer to function as the power receiver according to claim 1.

10. A power receiver including a vibrating unit, the power receiver comprising:

a power receiving unit configured to wirelessly receive power;

an inhibiting unit configured to inhibit the vibrating unit from vibrating when the power receiving unit receives the power; and

a notifying unit configured to, when the inhibiting unit inhibits the vibrating unit from vibrating, notify a user that the vibrating unit is inhibited from vibrating.

11. A method of controlling a power receiver including a vibrating unit, the method comprising:

an identifying step of identifying a power reception technique when power is received from a power transmitter; and

an inhibiting step of inhibiting the vibrating unit from vibrating in accordance with the identification.

12. A method of controlling a power receiver including a vibrating unit, the method comprising:

an inhibiting step of inhibiting the vibrating unit from vibrating when power is wirelessly received; and

a notifying step of, when the vibrating unit is inhibited from vibrating, notifying a user that the vibrating unit is inhibited from vibrating.
