Abstract

A mobile device and a power supply device are provided in which a first part of a connector detachably connects an electrical device to the mobile device, a second part of the connector matches the first part, and a converter generates electrical energy by converting energy of a mechanical movement into electrical energy, where the electrical energy is generated by relative mechanical movement occurring between first and second parts of the connector when the first and second parts are connected.

Claims

1. A mobile device comprising:

a first part of a connector for detachably connecting an electrical device to the mobile device, the electrical device comprising a second part of the connector, the second part matching the first part, and

a converter adapted to generate electrical energy by converting energy of a mechanical movement into electrical energy, the converter being integrated into the first part of the connector such that the generated electrical energy is generated by relative mechanical movement occurring between the first part and the second part when the first part and the second part are connected.

2. The mobile device according to claim 1, wherein the electrical device comprises a charger for charging the mobile device.

3. The mobile device according to claim 1, wherein the mobile device comprises a battery powered device selected from the group comprising a mobile device, mobile phone, a personal digital assistant, a mobile navigation system, and a mobile computer.

4. A power supply device, comprising:

a power converter for adapting electrical energy from an electrical power supply to electrical requirements of an electrical device,

a switch adapted to couple the power converter to the electrical power supply,

a first part of a connector for detachably connecting the power supply device to the electrical device, the electrical device comprising a second part of the connector matching to the first part,

a converter adapted to generate electrical energy by converting energy of a mechanical movement into electrical energy, the converter being integrated into the connector such that the generated electrical energy is generated by relative mechanical movement occurring between the first part and the second part when the first part and the second part are connected, and

a control circuit coupled to the switch and the converter, wherein the control circuit is adapted to supply the generated electrical energy from the converter to the switch to provide an electrical coupling of the power converter to the electrical power supply.

5. The power supply device according to claim 4, wherein the power supply device comprises a charger for charging the electrical device.

6. The power supply device according to claim 4, wherein the converter is integrated in the first part of the connector.

7. The power supply device according to claim 4, wherein the converter is integrated in the second part of the connector.
