Abstract: A speaker includes: a diaphragm having a dome shape; a tubular member having the diaphragm disposed inside, and having an inner diameter increasing toward a front; and a phase plug. The phase plug includes: a front surface, a rear surface facing a central portion on a front surface of the diaphragm at a constant interval in parallel, and a side surface connecting the front surface and the rear surface. A front surface of the phase plug is larger than a rear surface of the phase plug as viewed in a front-rear direction of a speaker. At least a part of a side surface of the phase plug has an inclined surface extending outward while extending forward, faces an inner circumferential surface of the tubular member and a front surface of the diaphragm, and directs a sound wave generated from the diaphragm toward an inner circumferential surface of the tubular member.

Abstract: A loudspeaker includes a diaphragm, a voice coil body, and a magnetic circuit. The diaphragm has a first side, which is the surface of a recess defined by a thin part and a thick part formed around the thin part. The voice coil body includes a bobbin and a voice coil. The bobbin has a first end connected to the thin part on the first side of the diaphragm and a second end opposite to the first end. The magnetic circuit has an inner part, an outer part, and a magnetic gap. Part of the magnetic circuit including the first side of the inner part is located from the second end of the bobbin into the bobbin, and the first side of the inner part and the first side of the outer part are located in the recess so that the voice coil is located in the magnetic gap.

Abstract: A loudspeaker includes a frame, a diaphragm, an edge connecting portion, a magnetic circuit having a magnetic gap, and a voice coil body. The edge connecting portion connects an outer peripheral end portion of the diaphragm and the frame to each other. The diaphragm is disposed inside of the frame. The diaphragm has a planer diaphragm and a reinforcing diaphragm. Both a front surface and a rear surface of the planer diaphragm are flat. The reinforcing diaphragm includes a thick portion and a recessed portion, and is joined to the planer diaphragm. The reinforcing diaphragm is made of resin. The thick portion is formed on an outer periphery of the reinforcing diaphragm. The recessed portion is formed at a center side of the reinforcing diaphragm.

Abstract: A method is provided for causing a processor included in a speaker system to execute operations. The operations include acquiring, using a measurement microphone, reflected sound information regarding an effect of sounds that are played back by a plurality of speakers having predetermined directivity and that are reflected off an object, where the plurality of speakers are included in the speaker system. The operations also include calculating correction coefficients used to correct acoustic characteristics of the plurality of speakers on the basis of the acquired reflected sound information. The operations further include correcting the acoustic characteristics of the plurality of speakers using the calculated correction coefficients.

Abstract: A speaker device for reproducing an audio signal includes a first speaker including a first diaphragm and a first magnetic circuit that drives the first diaphragm, where the first diaphragm reproduces an audio signal including a predetermined frequency range, a second speaker including a second diaphragm and a second magnetic circuit that drives the second diaphragm, where the second diaphragm reproduces an audio signal including a frequency range substantially the same as the predetermined frequency range, and at least one cabinet having the first speaker and the second speaker mounted therein so that radiation directions of sounds are opposite to each other. At least part of a space formed between the first speaker and the second speaker communicates with the outside of the cabinet. When the speaker device reproduces the audio signal, the first diaphragm and the second diaphragm vibrate in opposite directions.
