ELECTRONIC VIBRATIONAL DISPLAY

摘要

An electronic vibrational display unit comprises a casing (2) which supports six separately-energisable vibrational transducers (9). Each transducer (9) is associated with a respective display element (3) mounted in the casing (2). Each of the display elements (3) comprises a sender (3b) arranged to vibrate with the respective transducer (9) and a surround (3a) having an exposed surface large enough to accommodate a fingertip. The exposed surface of each surround (3a) has an aperture (3c) through which the tip of the associated sender (3b) is accessible to the fingertip. The arrangement is such as to enable a user to contact the exposed tip of each of the senders (3b) with a fingertip whilst resting that fingertip on the respective surround (3a). The display elements (3) are mounted in the casing (2) in such a manner that substantially the entire vibrational energy of a given transducer (9) is prevented from being transmitted via the casing to any other display element.
