20110266892 | VIBRATION GENERATING DEVICE - A vibration generating device includes a coil wound around an outer peripheral surface of a core, a vibrator vibrating due to a magnetic field generated by the coil, a magnetic field forming unit having a pair of magnets oppositely disposed at both surfaces of the vibrator so that the same polarities face each other or one magnet disposed at one side surface of the vibrator, and an elastic support member for supporting the vibrator so that the vibrator is capable of freely vibrating, wherein a vibrating direction of the vibrator is set to be parallel to a fixed surface of the device, by means of a magnetic flux generated by the magnetic field forming unit. | 11-03-2011 |
20120153748 | VIBRATION GENERATOR - An elastic support member that supports a vibrator includes a first elastic deformation portion and a second elastic deformation portion that are integrally formed from a leaf spring material. When the first elastic deformation portion bending-deforms in an X direction, the vibrator vibrates in the X direction. When the second elastic deformation portion bending-deforms in a Z direction, the vibrator vibrates in the Z direction. The elastic modulus of the second elastic deformation portion is higher than the elastic modulus of the first elastic deformation portion. A magnetic core and a coil are provided in the vibrator, and a magnet is provided on the case side. Driving signals of different frequencies are applied to the coil, and the vibrator resonates at a low vibration frequency in the X direction that is a first direction and resonates at a high vibration frequency in the Z direction that is a second direction. | 06-21-2012 |
20130061736 | VIBRATION GENERATOR - From analog music information in which the sounds of a plurality of musical instruments are mixed, sound data corresponding to the register of the reproduced sound of a bass guitar and sound data corresponding to the register of the reproduced sound of a drum are extracted using a band-pass filter. A drive pulse with a low frequency is generated within the periods of data sections in which the former sound data reaches a predetermined level or higher, and a drive pulse with a high frequency is generated within the periods of data sections in which the latter sound data reaches a predetermined level or higher. A vibrating body in a vibration mechanism unit is resonated by two drive pulses with frequencies, thereby causing vibration according to the reproduced sound of music. | 03-14-2013 |
20130069619 | INPUT DETECTION DEVICE - When a first driving signal is applied from a waveform output unit, detection current with a high frequency than a natural frequency of a vibrator is applied to a coil of a vibration generation unit. When the current fluctuates, induction power due to a counter-electromotive force is inducted to a external casing of the vibration generation unit. The induction power is changed in an input unit, and when a level of an output due to the change thereof greatly fluctuates, a second driving signal is output from the waveform output unit, and logical sum of the first driving signal and the second driving signal is applied to a driving circuit. At this time, a vibration current flows to the coil, and the vibrator vibrates by the natural frequency. | 03-21-2013 |
20130201127 | INPUT DEVICE - On a lower case serving as a supporting base, a movable unit is supported to be able to vibrate in an X direction, with a first elastic member interposed therebetween. In the movable unit, a panel assembly is supported on a movable base to be able to vibrate in a Z direction, with a second elastic member interposed therebetween. A vibration generator is mounted on the panel assembly and supported by a third elastic member on the movable base. When the vibration generator generates vibration in the X direction, the entire movable unit vibrates in the X direction. When the vibration generator generates vibration in the Z direction, the panel assembly vibrates in the Z direction. When the panel assembly is pressed with a finger, the force of the pressing operation can be detected by a second detector which is a force sensor. | 08-08-2013 |
