An object of the invention is to solve a problem that a cable exposed to an outside of a sound-emitting unit is tangled in fingers. In order to achieve the object, a headphone (1) includes: a sound-emitting unit (2) housing a speaker (48) having a diaphragm (49); and a cable unit (43) configured to transmit an electric signal to the speaker. The cable unit detachable from the sound-emitting unit is inserted in the sound-emitting unit from a bottom of the sound-emitting unit, disposed at an axially outer side than the diaphragm in a sound radiation direction of the diaphragm within the sound-emitting unit, and pulled from a top of the sound-emitting unit to an outside of the sound-emitting unit.


The merging support device is loaded on a movable body and acquires a current position of the movable body. The merging support device presents the recommended merging area when the movable body is on the merging lane. The recommended merging area is an area on the main lane where merging is recommended, and is preferably an area of a predetermined distance from an ending position of the merging lane.

A mirror device has a plurality of organic EL elements and a plurality of metal mirror surface portions that are divided by banks made of a light-transmissive dielectric material and aligned on a substrate. Each of the organic EL elements has an organic layer that is formed between a light-transmissive electrode and a reflection electrode and contains a light-emitting layer. Each of the metal mirror surface portions and each of the organic EL elements or each group of the metal mirror surface portions and each group of the organic EL elements are alternately disposed.


A breath sound analyzing apparatus is provided with: a first dividing device configured to divide a spectrum of breath sounds, on the basis of a plurality of reference spectra, which are standards for classifying the breath sounds; a second dividing device configured to divide at least one portion of the spectrum divided by the first dividing device, on the basis of a predetermined time-series characteristic; and an outputting device configured to output information regarding ratio of each of divided spectra included in the breath sounds, on the basis of the divided spectra by said first dividing device and said second dividing device. According to the breath sound analyzing apparatus, a plurality of sound types included in the breath sounds can be preferably divided.

A composite speaker device capable of restraining a disturbance in sound radiation characteristics caused by propagation of a sound from a tweeter unit to a woofer unit is provided. A composite speaker device (1) includes a first speaker unit (10,16) having a first diaphragm (11,16a), a second speaker unit (20,26) which is installed in a sound radiation direction (D1) of the first diaphragm (11,16a) and has a second diaphragm (20,26a) with a diameter smaller than that of the first diaphragm (11,16a), and a sound absorbing material (30,35,36,51,61) attached to the surface of the first diaphragm (11,16a) in the sound radiation direction (D1) so as to surround the second diaphragm (21,26a).


The disclosure discloses isolated polynucleotides and polypeptides, and recombinant DNA constructs useful for conferring improved tolerance in plants to insect pests; compositions (such as plants or seeds) comprising these recombinant DNA constructs; and methods utilizing these recombinant DNA constructs. The recombinant DNA constructs comprise a polynucleotide operably linked to a promoter that is functional in a plant, wherein said polynucleotides encode insect tolerance polypeptides.

A substrate (100) is a light-transmitting substrate. A light-emitting unit (140) includes a first electrode (110), an organic layer (120), and a second electrode (130). In addition, a light-emitting device (10) includes a first region (102), a second region (104), and a third region (106). The first region (102) is a region overlapping a second electrode (130). In a case where the second electrode (130) has light shielding characteristics, the first region (102) is a region through which light does not pass. The second region (104) is a region including an insulating film (150) among regions between a plurality of light-emitting units (140). The third region (106) is a region which does not include the insulating film (150) among the regions between a plurality of light-emitting units (140). A width of the second region (104) is smaller than a width of the third region (106).
