Abstract: A sound conversion efficiency is improved, and a sound quality is improved. Included are an oscillating element that is expanded and contracted in response to a drive signal, two oscillating bodies that are positioned on opposite sides across the oscillating elements, have end faces arranged respectively in contact with both ends of the oscillating element in an expanding and contracting direction, and are oscillated by expansion and contraction of the oscillating element, and an urging spring that urges the two oscillating bodies and press the end faces against both the ends, respectively. Thus, the oscillating element is expanded and contracted, and the oscillating bodies are oscillated with the end faces of the oscillating bodies urged by the urging spring being in contact with both the ends of the oscillating element in the expanding and contracting direction of the oscillating element. As a result, the sound conversion efficiency can be improved, and the sound quality can be improved.

Abstract: An image display unit according to an embodiment of the present technology includes an image display device, a primary shaft portion, a holding portion, a first acting portion, and a second acting portion. The primary shaft portion extends in a direction. The holding portion holds the image display device, and is connected to the primary shaft portion to be movable in parallel with the direction in which the primary shaft portion extends. The first acting portion is capable of moving the holding portion in a first direction extending in parallel with the direction in which the primary shaft portion extends. The second acting portion is capable of moving the holding portion in a second direction that is opposite to the first direction extending in parallel with the direction in which the primary shaft portion extends.

Abstract: Generation of a secondary sound source is inhibited, and a sound quality is improved. Included are a support fixed to a mount base, a speaker unit including a portion to be fixed, and a base casing holding the speaker unit, and the speaker unit is fixed to the support and the base casing with the portion to be fixed being sandwiched between the support and the base casing. With this configuration, the speaker unit will be held stably, a great oscillation from a diaphragm of the speaker unit is less transmitted to the parts other than the diaphragm of the speaker unit, to the member holding the speaker unit, or the like. Generation of a secondary sound source is inhibited, and a sound quality can be improved.
