Disclosed are sound output equipment that exhibits high efficiency while having a slim structure and a display device including the same.

Sound output equipment and display device

Disclosed is a method of manufacturing a solid oxide fuel cell using a calendering process. The method includes preparing a stack including an anode support layer (ASL) and an anode functional layer (AFL), calendering the stack to obtain an anode, stacking an electrolyte layer on the anode to obtain an assembly, calendering the assembly to obtain an electrolyte substrate, sintering the electrolyte substrate, and forming a cathode on the electrolyte layer of the electrolyte substrate.

Method of manufacturing solid oxide fuel cell using calendaring process

A display device is disclosed. The display device comprises: a display panel having a lower side; a speaker, positioned in the rear of the display panel and adjacent to the lower side of the display panel, for providing sound from the lower side of the display panel downward; and a reflector for reflecting the sound provided by the speaker forward, wherein the reflector covers the lower side of the display panel, extends along the lower side of the display panel, has an inner surface facing the speaker, and has a stepped shape which protrudes from the inner surface and extends along the lower side of the display panel.

Display device

The present disclosure relates to a display device comprising a display panel which outputs an image on a front surface thereof and is bendable, an exciter positioned on a rear surface of the display panel, for generating sound by vibrating the display panel, a vibration transmitting unit positioned between the exciter and the display panel, for transmitting vibrations of the exciter to the display panel, a control unit for controlling the display panel and the exciter, and a frame to which the display panel is fixed. As the display device uses the bendable display panel, such that the display panel itself can vibrate to output sound, the display device has an advantage in that there is no need to have a separate sound output device.

A display device is disclosed. An object of the present disclosure is to match reproduction frequency bands of sounds output from a plurality of speakers. Another object of the present disclosure is to match magnitudes of sounds output from a plurality of speakers. According to at least one aspect of the present disclosure, the present disclosure can match reproduction frequency bands of sounds output from a plurality of speakers. According to at least one aspect of the present disclosure, the present disclosure can match magnitudes of sounds output from a plurality of speakers.
