Title: Speaker device
Inventor: OOYABA TAKASHI
IPC: H04R9/04
Filed: 1981-06-30
Abstract: PURPOSE:To prevent the compression of a dynamic range through the compressed linearity, by splitting a conductor arranged in a magnetic gap into two conductors so that the conductors can generate a driving force in adverse direction with each other. CONSTITUTION:A conductor arranged in a magnetic gap of a magnetic circuit is split into two conductors 1 and 1'. With the conductor of a voice coil, the conductors 1 and 1' are separately wound on a coil bobbin. On the other hand, transistors 2 and 2' are biased and constant DC currents IDC and I'DC flows to the conductors 1 and 1' without no signal application to the bases. When an audio signal or a signal with inverted phase is applied to the base, the currents IDC and I'DC are modulated with the signal, resulting that a correct superimposing the audio current with inversed phase on the currents IDC and I'DC respectively is applied to the conductors 1 and 1'. Thus, the total current is constant as 2IDC and the heat generation for the whole device is made constant, preventing change of resistance value.

IPC: F04D17/08
Filed: 1992-04-21
Abstract: PURPOSE:To prevent the lowering of strength-rigidity of each disk even if formed extremely thin and prevent the generation of deformation and chattering vibration by disposing numerous blade bodies in each clearance between the respective disks forming a multilayer disk fan in such a way as to be shifted by the fixed distance in the virtual circumferential direction in each clearance. CONSTITUTION:With the rotation of a multilayer disk fan F, air is sucked from the inlet port 20 of a fan case 5, and flows into the fan F from the fan inlet F1 of disks 1 on the front side plate 5a side so as to form thin air layers (a) between the disks 1, 1. The thin air layers (a) move toward the outer periphery of the disks 1 by centrifugal force, and simultaneously flow out in the tangential direction from the outer periphery with the movement thereof accelerated further effectively by numerous blade bodies K provided at the disks 1 so as to be blasted from an exhaust port through a duct. At this time, each disk 1 is sufficiently supported by the blade bodies K bonded to the positions shifted by the fixed distance in the virtual circumferential direction in each clearance (d). The strength and rigidity of the disk 1 formed extremely thin are thereby improved remarkably so as to suppress the generation of deformation and chattering vibration.
