Title:
SPEAKER DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/099300
Kind Code:
A1
Abstract:
A speaker device (1), wherein a speaker unit (2) is fitted to a cabinet (4). An adsorbent (3) is disposed in a hollow space (R) inside the cabinet (4) to physically adsorb a gas in the hollow chamber (R). A phase inverting mechanism (8) inverts phase by resonating with a sound of a specific frequency radiated from the speaker unit (2) into the hollow chamber (R), and radiates that sound to the outside. The watertight means of the phase inverting mechanism (8) prevents moisture from invading from the outside of the cabinet (4) into the hollow chamber (R) through the phase inverting mechanism (8).
