  • Publication number: 20230189988
    Abstract: An anti-vibration device for sound equipment having a stress frame with an adjustable shape to form a complimentary shape to the sound equipment so that vibration is optimized by setting the adjustable shape. The anti-vibration device can be used in a rack with other anti-vibration devices or between sound equipment and a support platform. The anti-vibration device may also be used on top of the sound equipment while supporting a variable weight.

  • Publication number: 20200268151
    Abstract: An anti-vibration device for sound equipment includes an elastic stress frame, the elastic stress frame including a stress deformation portion and a plurality of support portions, the support portions protruding toward one side with respect to the stress deformation portion. The anti-vibration device prevents most resonance from intruding into the sound equipment, the elastic stress frame and the laminate plate for supporting the sound equipment, and the sound equipment can work stably without being influenced by sound waves and resonance, so as to achieve its own due performance, naturally reducing the distortion rate of outputted sound.

  • Publication number: 20170202332
    Abstract: A curling iron that winds a lock of hair about a barrel includes a body that surrounds the barrel and forms a hair-receiving space accessed through an opening in the body. The opening includes a circumferential portion extending about a distal end of the barrel, and a slot extending axially from the circumferential portion toward a proximal end of the barrel. The slot portion is disposed at a longitudinal end of the curling iron for receiving a lock of hair that is elongated parallel to the slot portion and pushed in crosswise. A resilient finger mounted to the body projects and normally closes the slot portion and holds the lock of hair in the hair-receiving space. A gating coupling connects the barrel to the body and provides relative movement between the barrel and the body, between open and closed position, for inserting and releasing a lock of hair.

  • Patent number: 9521890
    Abstract: A hair styling iron includes a handle to which a barrel is mounted, a heating element in the barrel, a rotary drive including a motor that rotates the barrel, a control circuit including a timer, and a momentary drive switch which is user actuable and connected to the control circuit for control of the motor. Actuation of the drive switch must be maintained to operate the rotary drive. The control circuit monitors at least one change of state of the drive switch to determine a starting time, and actuates an alarm after an elapsed time measured from the starting time. The elapsed time is calculated by the control circuit in direct proportion to an angle of rotation of the barrel relative to the handle that occurs between a first actuation of the drive switch and release of the drive switch immediately following the first actuation of the drive switch.

  • Patent number: 9237787
    Abstract: A hair styling iron has a handle to which a heated barrel is mounted and a motor for moving the barrel. The iron includes a drive switch which is user actuable and connected to the control circuit for controlling operation of the motor. The control circuit includes a timer and monitors at least one change of state of the user-actuable drive switch to determine a starting time, and actuates an alarm, or another response, such as a reversal of the motor to unwind the hair, after an elapsed time measured from the starting time. The elapsed time may be user-selected or calculated automatically depending upon the length of hair wound onto the barrel, with compensation for barrel temperature.

  • Publication number: 20070169369
    Abstract: The present invention relates to a hair drier with a 3-Dimensional control interface, comprising a housing, a control button, a power supply, a heating element and a control circuit. An electrical connection is set among the power supply, the heating element and the control circuit. The control button has a 3-D control interface and can control each functional element of the hair drier separately or synchronously. This hair drier is single-key controlled and various functions of the hair drier can be realized by easily changing the angle of the button to a different direction, or moving the button towards different directions. This hair drier is simple in structure, easy to operate and convenient to use.
