Claim 10

A hand microphone according to claim 6 in which said counterelectrode is mounted on the housing on the side opposite the direction of the sound source whereby it will be readily contacted by the palm of the operator''s hand.

Claim 11

A hand microphone according to claim 6 in which said counterelectrode comprises at least two portions mounted on the surface of said housing, said portions being mechanically separated but electrically interconnected.

Claim 12

A hand microphone according to claim 6 in which said control electrodes are positioned on said housing so as to be readily accessible to the fingers of the operator''s hand when holding the microphone.

Claim 13

A hand microphone according to claim 6 in which said control electrodes are positioned with respect to the fingers of the operator''s hand holding the microphone.
