  • Publication number: 20190260278
    Abstract: A mobile apparatus has a linear actuator configured to generate vibration and sound, and further includes: a display panel; a frame; and a linear actuator arranged on the frame and configured to vibrate at 50 to 300 Hz to generate a vibration signal or to vibrate at 50 to 20000 Hz to generate a sound signal. The frame encompasses a case for defining the external appearance with the display and an inner bracket on which electronic parts are to be arranged. As compared with a linear actuator that excites a display panel to generate only sound, the linear actuator that performs the vibration function should provide a strong vibration power, which may damage the display panel. This is the reason why the linear actuator is arranged on the frame, not on the display panel.
