  • Patent number: 11108002
    Abstract: When visible light (light having wavelength of 380 nm or more and 780 nm or less) is transmitted through a first light transmitting region (TR1) (a first light emitting portion (160a)), a second light transmitting region (TR2) (a second light emitting portion (160b)) and a third light transmitting region (TR3) (a first light transmitting portion (162)), more specifically, when light from a D65 light source is transmitted through the first light transmitting region (TR1), the second light transmitting region (TR2) and the third light transmitting region (TR3), both of a color difference between the first light transmitting region (TR1) and the third light transmitting region (TR3) and a color difference between the second light transmitting region (TR2) and the third light transmitting region (TR3) are both, for example, 0.4 or more and 6.5 or less in CIELAB.

  • Patent number: 11076233
    Abstract: Provided is a sound generation device wherein noise can be reduced in accordance with a predetermined frequency band. An elastic member (8) is provided to obtain a sound pressure characteristic having a sub-peak at a predetermined frequency on the lower side than a lowest resonance frequency, and a phase characteristic such that a change rate of phase difference is lowered around the predetermined frequency. When the phase characteristic is calculated by simulation or actually measured in advance and an input signal is controlled such that the generated sound has an opposite phase to the noise, the generated sound can be made less prone to deviate from the opposite phase to the noise even if a time difference is caused between noise sound collection and sound generation at around the predetermined frequency, with the result that the noise can be effectively reduced.

  • Patent number: 10779076
    Abstract: A damper and a speaker apparatus includes the damper, which suppresses damage to an oscillatory system from an excessive input signal, enabling an efficiency increase of the speaker apparatus. As a damper has a planar surface, undue deformation of the oscillatory system due to an excessive input signal is suppressed, and damage to the oscillatory system can be suppressed. Furthermore, since the deformation of a corrugation portion by a normal input signal is hardly prevented, a reduction in sound pressure of the speaker apparatus with respect to an input signal is suppressed, enabling an increase in efficiency. Furthermore, the planar surface is extended at a height in a thickness direction different from that of an attachment portion. Thus, rising portions are deformed when a voice coil bobbin is oscillated, enabling suppression of rupture of the damper in the vicinity of a boundary between the planar surface and the attachment portion.
