摘要： 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.

摘要： A light-emitting unit (140) is formed on one surface (101) of a substrate (100). Further, the light-emitting unit (140) includes a first electrode (110), an organic layer (120), and a second electrode (130). A covering member (180) covers the light-emitting unit (140). An integrated circuit (300) is arranged on the one surface (101) of the substrate (100). In addition, the integrated circuit (300) is electrically connected to at least one of the first electrode (110) and the second electrode (130). A protective member (400) is located in a region (105) between the covering member (180) and the integrated circuit (300). Further, the protective member (400) is provided so as to expose the entirety of a first surface (301) of the integrated circuit (300) on a side opposite to the substrate (100).

摘要： 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. This reduces conspicuousness of both of the first light transmitting region (TR1) and the second light transmitting region (TR2). Furthermore, it is possible to identify the first light transmitting region (TR1), the second light transmitting region (TR2), and the third light transmitting region (TR3)

An insulating layer (150) is formed over the substrate (100) and the first electrode (110) and includes an opening (152) overlapping the first electrode (110). An organic layer (120) is located within at least the opening (152). A light-transmitting second electrode (130) is formed over the organic layer (120). An intermediate layer (200) is formed in at least a portion of a region of a lateral side of the first electrode (110) overlapping the first electrode (110). A refractive index of the intermediate layer (200) is between a refractive index of the substrate (100) and a refractive index of the first electrode (110).

摘要： An acoustic conversion device for an active noise control is provided. The acoustic conversion device can effectively suppress or remove noise by controlling variation in a lowest resonance frequency. A volume of a closed space is smaller than an equivalent compliance air volume of a speaker unit. Therefore, motion of a vibration plate, an edge and a damper is suppressed, it is possible to restrain the edge and the damper from being deteriorated with time, variation in lowest resonance frequency can be suppressed, phase of emitted sound can be less prone to be deviated from opposite phase of noise, and it is possible to effectively suppress or remove noise.
