Claims7
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.
