  • Linear vibration motor
    Patent number: 10559994
    Abstract: A linear vibration motor for fixing a ring-shaped coil provided within the linear vibration motor using a simpler structure. A linear vibration motor in which an upper casing and a bracket are configured to have an integrated shape and fixed to the inside or upper side of the coil to form magnetism, thereby facilitating fabrication due to a simple structure, preventing a reduction of a vibration power through a small space, and minimizing a rise of a material cost. Accordingly, the coil within the internal space of the casing is stably fixed by providing a structure for fixing the coil through the simple process of the bracket itself. Furthermore, since parts forming the vibration motor and the linear vibration motor are integrated, an assembly process is simplified, performance is satisfied by realizing a reduced production cost, and a working process and price competitiveness is secured.

  • METHOD OF IMPLEMENTING BUTTON CLICK USING CONTROL OF INPUT SIGNAL
    Publication number: 20190065005
    Abstract: A technology for implementing a finer button click of a device including an LRA by reducing the falling time of an LRA after a click is implemented by controlling an input signal applied to the LRA depending on an operating characteristic of the LRA. A user's operational convenience can be improved by omitting a real button positioned in the front part of a mobile phone, and more smooth display watching and manipulation are made possible by increasing the size of a display. Furthermore, the button click of a device including an LRA can be realistically implemented by controlling only the frequency of an input signal without adding a separate device or a control circuit to the LRA.

    Abstract: A linear vibration generating device installed inside a cellular phone, a vibration bell or the like to generate vibration. Right after the power applied to the ‘circuit (a circuit generating and controlling vibration)’, which is one of elements constituting the linear vibration generating device, is turned off, the ‘circuit’ is configured as a short circuit. In addition, the linear vibration generating device can be easily manufactured since an additional space inside the linear vibration generating device is not required, and there is an outstanding effect of promptly removing residual vibration by increasing the amount of vibration damping after the vibration operation of the vibration generating device including a permanent magnet is finished.
