Publication number: 20170214306Abstract: The present invention makes thinness or widthwise compactness possible, while exhibiting the advantages of obtaining stable vibrations and excellent impact strength, just as in a linear vibration motor equipped with a fixed shaft. A linear vibration motor equipped with: a needle equipped with a magnet and a spindle part; a frame for slidably supporting the needle in one axial direction; a coil for driving the magnet in the one axial direction, and affixed to the frame; and an elastic member for imparting an elastic force to the needle in opposition to the driving force imparted on the magnet. Therein, the needle is equipped with a pair of shaft parts which project in opposite directions in the one axial direction, and the frame is equipped with bearings for slidably supporting the pair of shaft parts.Type: ApplicationFiled: July 27, 2015Publication date: July 27, 2017Applicant: Nidec Copal CorporationInventor: Yoshinori KATADA

Patent number: 9621015Abstract: A linear vibration actuator for which the positional accuracy of coils in the casing can be easily increased. A linear vibration actuator (1) in which a magnet (13) and a weight (15) are fixed. The magnet (13) and the shaft (20) form a magnetic circuit within a casing (2) causing reciprocating motion of the weight (15) and magnet (13), via a coil (24) within a casing (2). The linear actuator (1) includes a shaft (20) provided within the casing (2) and made from a magnetic material. A coil (24) is supported by the shaft (20) includes first and second coil parts (22, 23) arranged parallel to an axial line L and wound in opposing directions. A ring-like magnet (13) surrounds the coil (24) and the shaft (20). A weight is fixed to the magnet. A plate spring (17) biases the magnet (13) and the weight (15) along the shaft (20).Type: GrantFiled: February 14, 2014Date of Patent: April 11, 2017Assignee: NIDEC COPAL CORPORATIONInventors: Yoshinori Katada, Hirohiko Sonoki, Daisuke Higashi, Risa Matsumura, Sayaka Ueno, Honami Nakazawa, Yoshihide Tonogai

Publication number: 20140175955Abstract: A compact motor which avoids peeling and cracking of the circuit board wiring pattern upon bending the printed circuit board. A projecting part (13), projecting toward the bottom side of the bracket (5), is provided on the back surface (5c) of the bracket (5) of a compact motor. A board insertion groove (S) is formed between the projecting part (13) and the back surface (5c). The flexible printed circuit board (10), inserted inside the board insertion groove (S), abuts the projecting part (13) and is bent facing the back. When the printed circuit board (10) is inserted into the board insertion groove (S) and bent, the printed circuit board (10) is in a state abutting the curved part (13a) of the projecting part (13), so the curved part (13a) of the projecting part (13) regulates bending and, by doing this, stabilizes bending of the flexible printed circuit board (10).Type: ApplicationFiled: December 18, 2013Publication date: June 26, 2014Applicant: NIDEC COPAL CORPORATIONInventor: Yoshinori KATADA
