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.
Claims9
A speaker with drive mechanism comprising:
- a speaker support movably supporting a speaker enclosure;
- a memory for storing a first position of said speaker enclosure;
- means for receiving a signal indicating a speaker moving instruction;
- a driving mechanism for moving said speaker enclosure vertically to a second position;
- and
- said second position being related to said first position by a characteristic of said signal.
A speaker with drive mechanism comprising:
- a speaker support movably supporting a speaker enclosure;
- means for detecting a first position of said speaker enclosure relative to said speaker support;
- means for storing said first position;
- means for receiving a signal commanding speaker movement;
- said signal having a characteristic;
- a drive mechanism for moving said speaker enclosure vertically to a second position relative to said first position;
- and
- said second position being related to said first position by said stored characteristic.
A speaker system comprising:
- at least first and second speaker enclosures;
- a first speaker driver for driving said first speaker enclosure;
- vertically
- a second speaker driver for driving said second speaker enclosure;
- vertically
- a first control means for independently driving said first and second speaker enclosures to independent first and second positions;
- and
- a control means for conjointly driving said at least first and second speaker enclosures relative to said first and second positions, whereby said at least first and second speaker enclosures are moved together to positions which are relatively identical to their relative positions before operation of said second control means.
