Abstract: In an embodiment, an electroacoustic converter has an enclosure, piezoelectric sounding body, electromagnetic sounding body, passage, and wiring members. The piezoelectric sounding body includes a first vibration plate supported directly or indirectly on the enclosure, and a piezoelectric element placed at least on one side of the first vibration plate. The piezoelectric sounding body divides the interior of the enclosure into a first space and a second space. The electromagnetic sounding body has a second vibration plate and is placed in the first space. The passage is provided at the piezoelectric sounding body or around the piezoelectric sounding body, to connect the first space and second space. The wiring members are electrically connected to the piezoelectric element and led out toward the electromagnetic sounding body, from the piezoelectric element, through the first space or second space.

Abstract: [Object]
To provide a display device and an electronic device each capable of implementing both a force feedback function and a tactile function and having high strength.
[Solving Means]
A display device according to the present invention includes a display panel, a touch panel, a spacer, a tactile panel, and a piezoelectric actuator. The touch panel is placed on the display panel and has a first principal surface on the display panel side and a second principal surface on the side opposite to the first principal surface. The tactile panel is placed on the spacer and has a third principal surface facing the second principal surface with a gap between the third and second principal surfaces and a fourth principal surface on the side opposite to the third principal surface. The piezoelectric actuator is placed on the third principal surface and causes vibration. When a first thickness is defined as the thickness from the second principal surface to the fourth principal surface and a second thickness is defined as the thickness from the second principal surface to the third principal surface, the first thickness is 0.5 to 1.5 mm, is equal to or larger than the thickness obtained by adding 0.3 mm to the second thickness, and is equal to or smaller than the thickness obtained by adding 1 mm to the second thickness.-
