Speaker device and related acoustic deflecting module

A speaker device having a resonance chamber with adjustable volume, the speaker device comprising:

• a speaker chamber adapted to generate and output an audio signal outwardly;
• and
• an acoustic deflecting module disposed adjacent to the speaker chamber, an outer surface of the acoustic deflecting module being adapted to change a transmission direction of the audio signal, and an inner volume of the acoustic deflecting module being used as the resonance chamber with the adjustable volume, the acoustic deflecting module comprising:
• a base;
• a cover assembled with the base for providing an inner space;
• a plate being a solid structure disposed inside the cover in a shiftable manner, an edge of the plate slidably abutting against an inner wall of the cover to divide the inner space into the resonance chamber and an accommodating chamber;
• and
• a driving mechanism disposed inside the accommodating chamber and assembled with the plate, and adapted to shift the plate relative to the cover for adjusting the volume of the resonance chamber.
