摘要： An apparatus including a touch sensitive screen having a face adapted to receive a user's hand-writing via a hand-held stylus. The screen includes means exciting the screen to vibrate so as to transmit the vibration to the stylus to simulate the sensation of a writing implement writing on paper as the stylus is moved over the face of the screen. The apparatus may include means for period modulating the electrical signal applied to the exciting means and means for amplitude modulating the electrical signal. The apparatus may include means for sensing the velocity of movement of the stylus over the screen face and means for modulating the vibration according to the sensed velocity.

摘要： The invention relates to a method of making an actuator comprising a plurality of force elements and an actuator made according to the method. The method comprises providing a coupler for coupling force from the force elements to a load; calculating a transfer function for each force element wherein the transfer functions allow the force provided to the load to be predicted; determining an error functional which is indicative of any undesired dips in the predicted force; calculating the parameters of the force elements which minimize the error functional, and coupling force elements having the calculated parameters to the coupler to make the actuator.

摘要： Methods, systems, and apparatus, including computer programs encoded on computer storage media, for changing a distributed mode loudspeaker's fundamental frequency. One of the systems includes a distributed mode loudspeaker comprising an actuator that includes: a supported portion, and a cantilevered portion having a length, a first fundamental frequency, and adapted to create a force to cause vibration of a load to generate sound waves using the first fundamental frequency; a support element connected to the supported portion of the actuator and adapted to adjust, based on a change to a shape of the support element, a size of the length of the cantilevered portion to change the first fundamental frequency to a second fundamental frequency with which the load will generate sound waves; and a frequency selection module that provides a signal to the support element to cause the support element to change shape.

摘要： A system includes a device chassis with a back panel and a haptic conduction interface. An acoustic radiating panel, attached to the chassis, and the back panel define a space. A moving magnet actuator is positioned in the space and mechanically coupled to the acoustic radiating panel, the moving magnet actuator including an element having a thickness smaller than a first dimension of the space, the moving magnet actuator being configured to vibrate the element during operating. An electronic control module coupled to the moving magnet actuator is programmed to activate the moving magnet actuator with a haptic signal that displaces the element in the first direction an amount sufficient to cause the element to contact the haptic conduction interface, the haptic signal having an amplitude and frequency sufficient to generate a haptic response in the device chassis.
