Abstract
A speaker with drive mechanism includes a plurality of speakers which can be moved individually or moved simultaneously without variations in positioning. The speaker with drive mechanism includes a memory, a memory for storing a current position of the speaker. When remote control signals indicating a speaker moving instruction are received, the received remote control signals are counted and the current position stored in the memory is updated. The result moves the commanded speaker to an updated address. Remote control signals indicating a relative speaker moving instruction may also be used to update the address in the memory.
