Patent ID: 8385575

Claim:
A reflex enclosure, comprising: an enclosure body; constituted by a first shell body and a second shell body, said first shell body being disposed with one first sound outlet, and said second shell body being disposed with at least one second sound outlet; a loudspeaker, coupled to a position of said first shell body adjacent to said first sound outlet; at least one waveguide portion constituted by a first waveguide element and a second waveguide element, said first waveguide element being constituted by a first bottom wall and a first surrounding wall, one end of said first surrounding wall being coupled to said first bottom wall, said second waveguide element being constituted by a second bottom wall and a second surrounding wall, one end of said second surrounding wall being coupled to said second bottom wall; said second bottom wall being disposed with an opening and a through hole communicating with an inside of said second surrounding wall, a diameter of said second surrounding wall being smaller than said first surrounding wall, said first surrounding wall being disposed at a periphery of said second surrounding wall, another end of said first surrounding wall not contacting with said second bottom wall, another end of said second surrounding wall not contacting with said first bottom wall; and at least one vibration unit, coupled to said second bottom wall shielding said opening and positioned adjacent to said second sound outlet, said second bottom wall being coupled to said second shell and positioned adjacent to said second sound outlet; wherein, a hermetically sealed sound room is formed inside said enclosure body by coupling said loudspeaker, said waveguide portion and said vibration unit respectively to said enclosure body; when said loudspeaker generates a forward sound wave and a rearward sound wave, said forward sound wave propagates to an outside of said first shell body through said first sound outlet, and said rearward sound wave propagates in said sound room; from an outside of said first surrounding wall, said rearward sound wave is guided 360 degrees (in all directions) to bypass said first surrounding wall and said second surrounding wall, propagate to an inside of said second surrounding wall, and pass through said through hole to push said vibration unit to generate vibration to generate a corresponding sound wave, and said corresponding sound wave finally propagate to an outside of said second shell body through said second sound outlet.
