  • Publication number: 20230277926
    Abstract: Provided is a force feedback apparatus, including a rotation shaft, a force feedback module fixed to the rotation shaft, and a trigger movably connected to the rotation shaft. The force feedback module includes a housing fixed to the rotation shaft and having a first opening and a force feedback assembly received in the housing. The force feedback assembly includes a sliding block, an ejector pin, a first driving element, a second driving element, and a transmission portion fixed to the sliding block and extending through the first opening to abut against the trigger. The first driving element interacts with the second driving element to drive the ejector pin to drive the transmission portion to move to realize force feedback on the trigger. The force feedback apparatus requires no additional transmission structure and directly provides force feedback for the trigger in a timely manner, thereby reducing the assembly difficulty.

  • Patent number: 11703904
    Abstract: Provided is a force feedback apparatus, including a housing, a rotation shaft fixed to the housing, a trigger movably connected to the rotation shaft and movable relative to the housing, and a force feedback assembly. The force feedback assembly includes a driving magnet fixed to a side of the trigger toward the housing, an iron core fixed to the housing and arranged opposite to the driving magnet, and a driving coil wound around the iron core. The driving coil is energized to interact with the driving magnet to generate force feedback on the trigger. The force feedback apparatus requires no additional transmission structure and directly provides force feedback through interaction between two driving elements, thereby realizing timely force feedback on the trigger and reducing the assembly difficulty while simplifying the structure. In addition, forces in two directions can be directly generated on the trigger by changing a driving current.

  • Patent number: 11698655
    Abstract: The present disclosure discloses a force feedback device including a supporting bracket, a trigger hinged to the supporting bracket through a rotating shaft, a transmission shaft connected to the trigger, a driving assembly for providing an acting force to the trigger through the transmission shaft, and a reset member. A direction of the acting force is opposite to a direction of pulling the trigger. The driving assembly includes a magnetic circuit system and a coil fixed to the transmission shaft and generating an electromagnetic induction force with the magnetic circuit system. The electromagnetic induction force is transmitted to the trigger through the transmission shaft for forming the acting force. A handle using the force feedback device is also disclosed. The force feedback device and the handle disclosed by the present disclosure enable users to obtain richer game experiences according to different game scenarios.

  • Publication number: 20230201878
    Abstract: The present invention discloses electronic equipment with a vibration function, including a carrier and a vibration module configured for providing a vibration sense; the vibration module includes a housing having a receiving space and provided with an opening in at least one end; a vibration unit received in the receiving space and directly providing a vibration sense to a user; and an elastic member; the elastic member elastically connects the vibration unit to the housing, so as to elastically suspend the vibration unit in the receiving space. According to the electronic equipment of the present invention, in both cases where a surface of the carrier is a flexible material and the carrier is relatively heavy, local vibration can be provided through the independent vibration unit, so as to directly feedback vibration actually generated by the vibration unit to the user, thus improving the experience of the user.

  • Publication number: 20230094938
    Abstract: A touch feedback device and an electronic device are provided. The touch feedback device includes a touch panel; a linear vibration motor arranged on the touch panel and being able to drive the touch panel to vibrate; a mounting member; and a mounting base. The mounting member includes at least one fixing part and a body that is elastic. The touch panel is fixed to the body, and the at least one fixing part is configured to fix the body to the mounting base, in such a manner the touch panel is limited to vibrate along any direction in a horizontal direction. The natural frequency of the touch feedback device can be effectively regulated, and the linear vibration motor at any position on the touch panel does not have much effect on the vibration distribution of the touch panel, thereby improving the vibration touch of the touch feedback device.
