Abstract: Sound producing apparatus in the form of a pair of speakers each having a clamp affixed thereto. The clamp in each case defines a pair of relatively moveable opposed jaws which may be opened to attach the speaker to the periphery of the monitor of a laptop/notebook type computer. The clamp is affixed to the housing of the speaker by an additional clamp in a manner which permits the speaker to be vertically adjusted after being attached to the monitor. The clamps are formed as an integral unit which includes a base member having first and second slide members slidably attached to oppositely disposed outwardly facing planar surfaces of the base member with a spring urging each of the slides into a clamped or holding position.
