ABSTRACT:
An improved acoustic transport member for use in a keyboard having key operated strikers individually actuatable for inducing acoustic energy in the form of sound waves which propagate through the member from selected inducing positions therealong. A first portion of the member is fabricated in the form of a series of tabs to provide discrete impact positions for generating sound waves in response to impact actuation of related strikers. A second portion integrally connected with the first portion links all of the tabs and functions as a sound corridor for receiving and transporting all sound waves generated as a result of the selected striker impacting its related tab. An aperture is provided through the tabs. A peripheral rim of the aperture provides sound reflecting boundaries that define sound passages on the tabs for directing the sound waves in different directions in communicating the sound waves from the tabs into the corridor. As a result of the sound waves passing through the passages, distinct wave separation is accomplished. A top portion of the peripheral rim is located along the base of the corridor for reflecting the traveling waves in a manner substantially preventing the waves from entering into areas of passing tabs, thus confining the propagating sound waves within the corridor portion of the member. By controlling the sound waves through the passages and substantially trapping the propagating sound waves within the corridor, dispersion of the sound waves is effectively minimized.
