The invention claimed is:1. A method of operating a first hardware element in a system comprising one or more servers and one or more second hardware elements, the method comprising:detecting voice or sound using a microphone in the first hardware element;connecting the first hardware element to the one or more servers via wireless communication, each server including a memory storing functional information indicating a capability of each of a plurality of hardware elements located remotely from the server;transmitting, from the first hardware element, data based on the detected voice or sound to identify a function capable of being performed by linking the first hardware element and the one or more second hardware elements;receiving, at the first hardware element, an instruction signal generated based on the identified linkage operation; andperforming, based on the received instruction signal, the identified function with the first hardware element and the one or more second hardware elements, the one or more second hardware elements including output circuitry.2. The method according to claim 1, further comprising:outputting audio information.3. The method according to claim 2, wherein outputting the audio information includes using the first hardware element to operate as a speaker, a headphone or an earphone.4. The method according to claim 3, wherein outputting the audio information includes outputting a sound effect or an alert.5. The method according to claim 3, wherein one or more second hardware elements is configured to perform a lamp function, the method further comprising controlling the lamp function based on the transmitted data.6. The method according to claim 2, wherein outputting the audio information includes outputting a sound effect or an alert.7. The method according to claim 1, wherein one or more second hardware elements is configured to perform a lamp function, the method further comprising controlling the lamp function based on the transmitted data.8. The method according to claim 1, wherein the wireless communication is one of Bluetooth, WiFi, and a mobile communication network.9. A first hardware element used in a system comprising one or more servers, and one or more second hardware elements, the first hardware element comprising:a microphone to detect voice or sound; andcircuitry configured toconnect to the one or more servers via wireless communication, each server including a memory storing functional information indicating a capability of each of a plurality of hardware elements located remotely from the server,transmit data based on the detected voice or sound to identify a function capable of being performed by linking the first hardware element and the one or more second hardware elements,receive an instruction signal generated based on the identified function, andperform, based on the received instruction signal, the identified function with the first hardware element and the one or more second hardware elements, the one or more second hardware elements including output circuitry.10. The first hardware element according to claim 9, wherein the circuitry is further configured to output audio information.11. The first hardware element according to claim 10, wherein the first hardware element is configured to operate as a speaker, a headphone or an earphone.12. The first hardware element according to claim 11, wherein the audio information includes a sound effect or an alert.13. The first hardware element according to claim 11, wherein one or more second hardware elements is configured to perform a lamp function.14. The first hardware element according to claim 10, wherein the audio information includes a sound effect or an alert.15. The first hardware element according to claim 9, wherein one or more second hardware elements is configured to perform a lamp function.16. The first hardware element according to claim 9, wherein the wireless communication is one of Bluetooth, WiFi, and a mobile communication network.
