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.

Speaker with drive mechanism

A disk player has a magazine for storing disks and a disk transport mechanism transporting a selected disk between a playback position outside the magazine and a store position located entirely within the magazine. The carriages are stacked upon each other and pivotally supported within the magazine. The carriages are extracted from the stack by lifting a front end of a carriage above a selected carriage. A transport mechanism moves carriages between the magazine, the playback position and an eject position. A disk sensor senses the presence of a disk in the transport mechanism before the carriage is reinstalled in the magazine and a memory updated to indicate that the selected carriage is occupied by a disk. If an extra disk is inadvertently placed on the selected carriage, after the transport mechanism reinstalls the selected carriage, the sensor indicates that a disk remains on the transport mechanism. The transport mechanism then brings the extra disk to the eject position before moving the magazine to prevent the extra disk from being damaged by the movement of the magazine.
