The present disclosure is to provide a wireless sound device capable of effectively receiving a command that meets a user's intention without an error despite a user input unit having a limited size, and a method for controlling the same. For example, a wireless sound device includes a wireless communication unit for wireless communication with an external device, a touch sensor for sensing a touch input of a user in a touch standby mode, a force sensor for sensing a force based on the touch input, a sound output unit for outputting an audio signal received from the external device, and a controller that controls a touch mode of the wireless sound device to be switched to a touch accepting mode or a touch ignoring mode in response to the touch input, and, when a touch validity of the touch input is positive, the controller controls the touch mode to be switched to a touch accepting mode or a touch ignoring mode based on a force validity of the touch input.

An electronic device can include a housing defining an aperture and a display positioned in the aperture. The display and the housing can define an internal volume in which a speaker assembly is positioned. The speaker assembly can include a speaker module and a speaker enclosure in fluid communication, with the speaker enclosure at least partially defining a speaker volume.

Aspects of the present disclosure relates to user interface systems and methods for use in head-worn computing systems.

A display apparatus is disclosed, which includes a display panel including a first area and a second area, a first rear cover disposed below a rear surface of the display panel, a first sound generating module arranged in the first area to adjoining the display panel, and a second sound generating module arranged in the second area to be spaced apart from the display panel, wherein the first rear cover includes a first rear cover port hole formed to overlap the second sound generating module, the second sound generating module includes an enclosure disposed below a rear surface of the first rear cover and coupled with the first rear cover, and a second sound generating unit mounted in the enclosure, and the enclosure includes an enclosure port hole overlapped with the first rear cover port hole.

An electronic device is provided. The electronic device includes frame constituting at least a part of the side exterior of the electronic device, an internal mechanical element disposed inside the frame, multiple frame holes formed through the frame at a predetermined interval in an identical shape, an air channel comprising a first hole, at least a part of which is formed through the internal mechanical element in a first direction so as to be connected to at least one of the multiple frame holes, and a second hole formed through the internal mechanical element in a direction perpendicular to the first direction so as to be connected to the first hole, an air vent disposed in the second hole of the air channel, and a speaker channel connected to remaining holes of the multiple frame holes and connected to a speaker module.

Wearable devices may include a housing including a first surface facing a first direction and having a speaker nozzle part, and a second surface facing a second direction opposite to the first direction and having at least one microphone hole. A speaker and a microphone are disposed in the housing, the microphone configured to collect an acoustic signal. A partition wall is positioned between the speaker and the microphone. A first space is defined between the speaker and the partition wall, a first path is provided for connecting the speaker and the speaker nozzle part, and a second path, separated from the first space by the partition wall, connects the microphone and the first path.

A display device includes a display panel, and a heat-dissipating member disposed on the display panel and including a conductive metal.
