Abstract: A damper device that suppresses arc discharge between electrodes generated by bubbles in an electro-rheological fluid, includes an inner tube housed in an outer tube forming an outer shell of a damper device. An electrode tube is arranged between the outer tube and the inner tube. An electro-rheological fluid is sealed in the outer tube. The inner tube and the electrode tube constitute a cathode and an anode, respectively, and apply a voltage to the electro-rheological fluid located between the inner tube and the electrode tube. An insulating layer is provided on a surface of the electrode tube on a side facing the inner tube or on a surface of the inner tube on a side facing the electrode tube. When a maximum voltage applied to the electro-rheological fluid is Vmax (V), a thickness t (m) of the insulating layer is set to satisfy Formula (1).

Abstract: A vibration isolator includes a first conical disc spring member having a first end and a second end. A first-end spacer in contact with the first spring member first end, and a second-end spacer in contact with the first spring member second end. A second conical disc spring member has a first end and a second end. The second spring member first end is in contact with the first-end spacer. Another second-end spacer is in contact with the second spring member second end. A flexible housing of the isolator defines an interior. The housing is in contact with and extends between the second-end spacer and the other second-end spacer so that the first-end spacer and the first and second spring members are received in the housing interior.

Abstract: A linear vibration motor comprises: a motor housing, a stator, a vibrator, and at least two sets of elastic support assemblies for suspending the vibrator in the motor housing and for supporting the vibrator and providing an elastic restoring force. The elastic support assemblies are located between the inner wall of the motor housing and the vibrator, each set of the elastic support assemblies comprising at least two elastic supports. The elastic support comprises a first connection point fixedly connected to the vibrator and a second connection point fixedly connected to the inner wall of the motor housing. The second connection point is coupled to a side wall of the motor housing parallel to the vibration direction of the vibrator. The first connection point and the second connection point of the elastic support are located at the same side of the central axis of the vibrator parallel to the vibration direction of the transducer. The structure of the linear vibration motor is simplified, the vibration support assemblies have better vibration effect, and give the user a good experience.
