Abstract
A touchsensing device for localizing mechanical impacts on a tactile plate, with at least one acoustic transducer mounted on the tactile plate by means of an acoustic isolator, such that the acoustic transducer and the tactile plate are in direct contact with each other and the acoustic transducer is acoustically shielded by the acoustic isolator. Thus, acoustic waves can be detected with little distortions and the reliability of the touch sensing device can be improved. Also, a touch sensing device having a tactile plate and a sensor module having at least one acoustic transducer and a fastener to fix the sensor module to the tactile plate, wherein the fastener is a sticky tape, in particular a double sided sticky tape.
