摘要： A material for improving the sound pressure level at the bass reproduction limit of the present invention is composed of an activated carbon having a cumulative pore volume of 0.4 ml/g or more for the pores each having a radius of 50 angstroms or less. Preferably, this activated carbon has a cumulative pore volume of 0.1 ml/g or less for the pores each having a radius of 7 angstroms or less. In particular, when a sound pressure level improving material in which the activated carbon has a cumulative pore volume of 0.5 ml/g or more for the pores each having a radius of 18 angstroms or less is installed in a cabinet of a loudspeaker device, the material alleviates pressure fluctuations of a gas within the cabinet caused by vibration of a loudspeaker, and thus a very good bass reproduction effect is attained. Moreover, in the case where a sound pressure level improving material in which the activated carbon has a cumulative pore volume of 0.4 ml/g or more for the pores each having a radius of 18 to 50 angstroms is installed in the cabinet, a loudspeaker device having a good bass reproduction effect even in an atmosphere of high humidity is obtained.

摘要： A loudspeaker unit (2) of a loudspeaker system (1) is fitted to a cabinet (4). An absorbent (3) is disposed in a hollow chamber (R) inside the cabinet (4) and absorbs a gas inside the hollow chamber (R). A phase inverting mechanism (8) inverts the phase by resonating with a sound of a specific frequency radiated from the loudspeaker unit (2) into the hollow chamber (R) and radiates this sound to outside. The watertight means of the phase inverting mechanism (8) prevents invasion of moisture into inside the hollow chamber (R) from outside the cabinet (4) through the phase inverting mechanism (8).

摘要： A vibration device includes a support system member that supports a diaphragm to allow vibration, a tubular voice coil bobbin attached to the diaphragm, and a magnet disposed on at least one of inner and outer circumferential surface sides of the bobbin. The magnet is polarized in a vibration direction of the diaphragm, and forms a magnetic gap on a side that faces the bobbin. A voice coil is attached to the bobbin and disposed within the magnetic gap, and vibrates the diaphragm and the bobbin in response to a driving force generated when an electrical signal is inputted into the voice coil. A magnetic material member is attached to the bobbin, disposed in a balancing position within the magnetic gap, and, when vibrating with the bobbin, subjected to a magnetic attractive force in a direction away from the balancing position.
