  • Publication number: 20200352454
    Abstract: An electronic valve with: a yoke including an end plate portion and a side plate portion; a pole piece; a solenoid coil; and a diaphragm made of a plate-shaped magnetic material. The pole piece has an opening at one end portion and a first fluid inlet/outlet communicating with the opening at the other end portion. A biasing unit biases the diaphragm in a direction away from one end portion of the pole piece in a manner of moving the diaphragm translationally in one direction. In a non-operating time, the electronic valve comes into an open state where the opening is open. In an operating time, the diaphragm approaches the one end portion of the pole piece against the biasing force of the biasing unit by a magnetic force generated by the solenoid coil, and the electronic valve can come into a closed state where the opening is closed.

  • Patent number: 8155344
    Abstract: A vehicle speaker including a panel, a giant magnetostrictive vibrator, and a vibration transmission pad. The panel is used as a diaphragm for producing high-frequency sound and forms part of a vehicle. The giant magnetostrictive vibrator is used as a vibration exciter for the panel and includes a vibration output shaft that vibrates in accordance with a signal for producing high-frequency sound. The vibration transmission pad is fixed to the panel and connected to the vibration output shaft in a manner enabling vibration transmission. The vibration transmission pad vibrates the panel when the vibration output shaft vibrates.
