Loudspeaker device and audio output apparatus having the same

An audio output apparatus comprising:

• one or more loudspeaker devices;
• and
• an audio processor configured to process an audio signal to make a sound from the loudspeaker device,
• at least one of the one or more loudspeaker devices comprising
• a frame comprising a bottom portion having a curved surface along a first direction and a pair of lateral portions provided at lateral sides of the bottom portion;
• a plurality of magnets curved along the curved surface of the bottom portion and arranged to be spaced apart from each other;
• a diaphragm supported by the pair of lateral portions, the diaphragm being curved along the curved surface of the bottom portion, and spaced apart from top surfaces of the plurality of magnets;
• and
• a coil provided on the diaphragm at positions corresponding to spaces between the plurality of magnets, the coil being configured to drive the diaphragm to vibrate in a direction perpendicular to the surface of the diaphragm by a magnetic field formed by the plurality of magnets as the audio signal processed by the audio processor is electrically applied,
• wherein the bottom portion is bent outward in the middle toward the direction of outputting a sound and the diaphragm, the coil and the plurality of magnets are bent such that curvatures thereof correspond to one another.
