Foot-Operated Sound Mixer

摘要

The present invention provides a foot-operated sound mixer, which, for example, allows a musical performer to adjust personal monitor mix by foot without using hands engaged in playing a musical instrument. The sound mixer of this invention has a housing that has at least one opening. The sound mixer of this invention also comprises an assembly of foot-controlled elements of a user interface comprising scroll wheel assembly and keys that are provided within the housing. The scroll wheel assembly includes a rotatable member positioned within the opening of the housing. The rotatable member is rotatable about an axis that extends within the housing and is laterally movable within the opening relative to the housing. The scroll wheel assembly also includes a movement sensing system that determines when the rotatable member is moved laterally relative to the housing. The keys of said assembly of foot-controlled elements of a user interface are positioned perpendicularly to the scroll wheel rotation axis and at such distance on both sides from the rotatable member so that human foot, when put on the rotatable member, reaches and can activate the keys by tip or toe while the middle part of the foot still touches and remains control of the rotatable member. In present embodiment of the invention said rotatable member is for adjustment of volume level of an audio channel in a monitor mix. In present embodiment of the invention said keys are for audio channel selection.
