Electro-optical device and electronic apparatus
View Patent ↗An electro-optical device includes an electro-optical panel, a sound-production frame that is disposed on a rear surface of the electro-optical panel and that constitutes a sound-production space, together with the electro-optical panel, and a sound-production vibrating body that is fixed directly to the sound-production frame in the sound-production space.
1. An electro-optical device comprising:
an electro-optical panel including a rear surface;
a sound-production frame that is disposed at the rear surface of the electro-optical panel, the sound-production frame defining at least part of a sound-production space located between the sound-production frame and the rear surface of the electro-optical panel; and
a sound-production vibrating body that is fixed directly to the sound-production frame at a position within the sound-production space so as to divide the sound-production space into two different open spaces;
wherein the sound-production frame includes:
a fixing inner surface portion to which the sound-production vibrating body is fixed; and
an opposing inner surface portion that faces a vibration side of the sound-production vibrating body separated by a space. the opposing inner surface portion being formed with a protrusion. and the fixing inner surface portion including an upper surface of the protrusion.
2. The electro-optical device according to claim 1 , wherein the sound-production vibrating body is disposed so as to overlap the electro-optical panel in plan view.
3. The electro-optical device according to claim 1 , wherein the sound-production vibrating body is a piezoelectric vibrating body including a vibrating plate and a piezoelectric body stacked on each other.
4. The electro-optical device according to claim 1 , further comprising a panel-holding frame that holds the electro-optical panel, the sound-production frame being a separate member from and being fixed to the panel-holding frame.
5. The electro-optical device according to claim 4 , further comprising a support member that is interposed between the panel-holding frame and the sound-production frame and that defines the sound-production space with the sound-production frame.
6. The electro-optical device according to claim 1 , wherein the opposing inner surface portion includes an air inlet.
7. An electronic apparatus comprising: the electro-optical device according to claim 1 ; and a control unit that controls the electro-optical device.
