An electronic device includes a display, a bracket for supporting at least a part of the display, and an acoustic actuator. The acoustic actuator is arranged under the display and includes a vibrating portion for transferring waves to the display and a fixed portion of which at least a part is fixed by the bracket. and the electronic device further includes at least one recess structure of which at least a part is arranged to be spaced from the acoustic actuator. The recess structure is formed to have an acoustic impedance that differs from the acoustic impedance of the bracket which is adjacent to the recess structure.

Electronic device including acoustic actuator

An electronic device comprises a speaker module which includes a speaker unit and a first speaker housing that is coupled to the speaker unit in a first direction. The first speaker housing accommodates the speaker unit, and is arranged in the inner space of the electronic device. An opening for radiating sound allows the inner space of the electronic device to communicate with the outside, and an acoustic passage connects the opening for radiating sound and a portion from which a sound is radiated by the speaker unit of the speaker module. The speaker module can further include an airtight member for sealing a gap between the speaker module and the acoustic passage so that the sound radiated from the speaker unit is transmitted to the acoustic passage.

Speaker module and electronic device including speaker module

In various embodiments, an electronic device includes: a diaphragm, a speaker module including a speaker configured to output a sound through a vibration of the diaphragm, and a housing accommodating the diaphragm and the speaker module therein and including a first space provided in a first direction from the speaker module and a second space provided in a second direction opposite the first direction. The electronic device further includes an air adsorption member comprising an air adsorbing material disposed in the first space and having a volume ratio of 90% or less of the first space, the air adsorption member configured to reduce air resistance to the diaphragm disposed above the speaker module without limiting the vibration of the diaphragm.

Electronic device including air adsorption member and speaker module

In various embodiments, a speaker module includes: an air adsorption member, and an electronic device includes the speaker module. The speaker module may include a yoke defining one surface of the speaker module, a magnet attached to the yoke through a first surface of the magnet, a plate attached to a second surface of the magnet, a frame providing a lateral surface of the speaker module and combined with the yoke at a first end of the frame, a voice coil disposed to be spaced apart from the magnet, and a diaphragm combined with the voice coil at an inner surface of the diaphragm. At least one of the yoke, the magnet, the plate, and the frame may include at least a portion of an air adsorption member comprising an air adsorption material configured to adsorb air in the speaker module based on the diaphragm vibrating.

An electronic device is provided. The electronic device includes a multi-channel speaker system, and an electronic device according to an embodiment of the disclosure includes a housing, a display which is attached to the housing to be seen from the outside, an actuator which is attached to a back surface of the display to vibrate the display and to generate a sound of a first frequency band, a hole which is formed on one side surface of the housing, and a speaker which is positioned on a region adjacent to the hole to generate a sound of a second frequency band different from the first frequency band through the hole. The actuator includes a first actuator which is attached to a certain region of the back surface of the display to vibrate the display, and a second actuator which is attached to a back surface of the display spaced apart from the first actuator by a designated distance to vibrate the display.

Electronic device including multi-channel speaker system

An electronic device is provided. The electronic device includes a housing including a first plate disposed to face a first direction, a second plate disposed to face a second direction opposite to the first direction, and a side member enclosing at least part of a space between the first and second plates and having at least one speaker hole constructed thereon, and a speaker device disposed between the first and second plates to emit a sound through the speaker hole. The speaker device may include: a speaker unit including a yoke disposed to a first face facing the first direction and a diaphragm disposed to a second face facing the second direction, wherein the diaphragm is disposed to face the second direction, and is disposed to face at least part of the second plate, an enclosure shaped to enclose at least part of the speaker unit and disposed between the first and second plates, an acoustic duct constructed between the enclosure and the second plate and extending towards the at least one speaker hole, and a ferromagnetic material disposed between the first plate and the yoke.

Electronic device having speaker

A mobile communication device is provided. The mobile communication device includes a display, a supporting member disposed under the display and having a hole, and a vibration actuator attached to the supporting member, where the vibration actuator does not overlap the hole when seen substantially perpendicular to the display, and where at least a portion of a region surrounding the hole of the supporting member is vibrated by vibration generated from the vibration actuator, whereby a sound signal having a predetermined frequency to be used for voice communication is generated.

Electronic device including a display panel speaker

An electronic device having a speaker device. The electronic device may include a housing, a speaker device disposed inside the housing, and a sound generation circuit electrically connected to the speaker device. The speaker device may include a sound generation plate movable in a first direction, and a sound reflection construction facing the sound generation plate to form a space between the sound generation plate and the sound reflection construction. The sound generation plate includes a first surface disposed substantially at a center of the sound generation plate, the first surface having a convex shape when viewed from inside the space, and the sound reflection construction includes a second surface substantially aligned with the first surface along an axis of the housing, the second surface having a concave shape when viewed from inside the space.

Speaker device for improving sound quality in high frequency band

A headset includes a first speaker; a second speaker; a connector connecting the first speaker and the second speaker; and a switch configured to generate different electrical signals according to states in which the first speaker and the second speaker move close to and away from each other, wherein the electrical signals are used to selectively control an output of contents that is being output from the headset.

Automatically controllable sound accessory

A slim electronic device is provided. The slim electronic device includes a substrate having an opening formed therein, and an audio component accommodated in the opening of the substrate without overlapping the substrate and disposed such that the top and bottom thereof are substantially parallel to the top and bottom of the substrate.
